Klip-Tite™ The multi award-winning Klip-Tite™ profile has been an intricate part in the success factor of many buildings decorating the South Africa sky-line. Companies like Cell C, Cummins Africa, Hirt and Carter and Amrod™ preferred Klip-Tite™ to cover their assets. With design traits similar to the popular Klip-Lok 700™, the Klip-Tite™ profile introduced transverse stiffeners, in lieu of the traditional longitudinal pan stiffeners, forming structural members spanning across the width of the pan. The deflection of the pan is thus reduced, increasing the wind uplift resistance of the sheet. These transverse pan stiffeners are a first in the South African sheeting market. Site-rolling is also available.

CRITICAL CHANGES AHEAD FOR PLASTIC TANK MANUFACTURERS New industry tank standard oers a quality compliant guarantee on plastic water and chemical storage tanks

The Association of Rotational Moulders of Southern Africa (ARMSA) announced a new South African industry tank standard for polyethylene chemical and water storage tanks.

The SANS 1731:2017 standard, developed in conjunction with the South African Bureau of Standards (SABS), offers a warranty to members of the broader construction, plumbing, architecture and design, landscaping and built industry as well as to home owners that tank manufacturers conform to world best practise.

Productivity Engineering Services and Consultants (PESC), an independent auditing company appointed by ARMSA, will regularly audit tank manufacturers and issue SANS 1731:2017 certificates to those who comply.

As I looked through the featured architectural projects in this issue of Leading Architecture & Design before we went to print, it struck me that they represent very different interpretations of what “leading architecture” might mean.

Take the first two projects. The Gateway West building in Waterfall City in Midrand, Johannesburg, is a placemaker – a dazzling sculptural form that creates an identity for the burgeoning urban node and a dramatic sense of arrival. On the other hand, the spectacular new building for the Norval Foundation – a hugely exciting arts and cultural centre in Cape Town – doesn’t lack a sense of presence, but prioritises its function as a showcase for the art treasures inside and around it rather than competing

with them. Its genius is as much in the spaces it creates for the art inside it as in the way it frames its spectacular views.

Then, if you take a look at Schulphoek House, a hotel renovation and extension in Hermanus, we have an example of leading architecture as a pioneering exercise in construction methods, materials and energy efficient technology. In a way, it’s all about the aspects of the architecture that you can’t see at all! It’s a reminder of how many different facets there are to the field of architecture, and how many ways there are of pushing the envelope. Architecture might be the slowest-moving of the arts, but it certainly doesn’t sit still.

Kigali Architecture School in dynamic light PHOTOGRAPHY EDWIN SEDA

T

he new Faculty of Architecture at the University of Rwanda’s College of Science and Technology campus, situated in the Nyarugenge district in Kigali, is inspired by the colours and shapes of its natural context.

Its prismatic forms, combining traditional and contemporary elements, were inspired by the surrounding landscape – broken down into canyons and fault lines – with the central fault line serving as the outdoor living space.

The building’s materials evoke the four elements: orange (representing fire), the inner garden (representing water), the circulation (harnessing air), and rammed earth and volcanic rock (introducing earth).

Local wood was used for the joinery and ceilings – and local and traditional construction methods mean that local skills and economies benefited. Everywhere, simple solutions were preferred, especially natural light, ventilation and temperature regulation.

The separate parts of the building have individual identities, inside and out, linked with paths and foot bridges. They add to the dynamism of the architecture and depict how the distinctive appearance of the parts make up the whole. www.schweitzer-associes.com

In a recent partnership with up-and-coming French architects Patrick Schweitzer et Associés Architecture, photographer Edwin Seda – himself an architect – has set up a series of photographic essays that capture the new Faculty of Architecture and Environmental Design in Kigali in dynamic light.

“Architecture is created to work with natural light, but is never really in control of this aspect,” says Seda. “My work on the Kigali school therefore explores light as a medium for spatial transformation, a sort of fourth dimension which only materialises once buildings and spaces are complete and the seasons begin to change.”

The photo series explores the spaces of the buildings as honest and almost naked, and as a perpetual, continuous canvas for the sun as it creates new paths for light to shape surfaces.

“The images are therefore constant pursuits of the narrative of light and human experience, explored through internal and external spaces,” says Seda.

“Although sometimes somewhat accidental, the images are purely honest in the way they portray light and space, as this is how we perceive the spaces we walk in.”

T

he Gateway West building is located at the main entrance of Waterfall City between Sandton and Pretoria.

Waterfall City is the largest urban concept development in South Africa, and Gateway West stands directly in front of the recently completed Mall of Africa. It is the first of two identical buildings that will frame the northern piazza and entrance to the Mall of Africa.

Given that the site is on a high point that’s clearly visible from the N1 highway, the forms and façades of the two buildings needed to be bold and progressive, acting as a prominent landmark.

At the same time, it was

16 LEADINGARCHITECTURE & DESIGN JUNE/JULY 2018

important to consider the function of Gateway West as a critical aspect of the urban design of Waterfall City, which is envisioned as an integrated and sustainable mixed-use, live-work environment.

The prominent pedestrian and sightline axis running through the site serves as a critical link through the length of the city.

The building’s star-shaped plan, along with its sweeping curves and dramatic cantilevers, create an appropriately iconic sculptural form, while responding to three critical (and very different) edge conditions: a sloping street edge to the north; a prominent urban piazza with reflection pond to the east; and to the south, the parking and back-ofhouse façades of the Mall of Africa,

which needed to be screened.

Moulded landscape berms ground the wings of the building and give them a sense of weight.

They also serve to screen the offices and create privacy while softening the street edge.

The main entrance is via the piazza and a light-filled, triple-volume atrium, which creates a visual connection not just with the piazza and the buildings, but through and between its wings as well.

Each wing has been designed to connect around the central atrium, where the building’s services, ablutions and vertical circulation are located – making it possible for it to house three different tenants per floor, or a single tenant.

PRO J EC T # 1 GATEWAY WEST

Gateway West comprises four basement levels of parking and seven office levels above ground, with four lifts serving all floors.

The façades are a combination of lightweight steel frame construction with expanded polystyrene (EPS) and composite aluminium cladding, which enable the curved façades and “liquid” finish with excellent thermal insulation to occur.

A combination of double and single glazing with sun-screen louvres have allowed the architects to ensure optimal thermal performance. At its base, the sleek finishes contrast with heavier, earthy materials, including stone, timber and landscaped berms.

The project addresses multiple sustainability and environmental factors, including water and energy efficiency, green transportation, sustainable materials and indoor air quality. A combination of a grey water harvesting system and lowflow fixtures ensures 40% savings in water consumption.

High-performance façades and reflective roof finishes reduce the cooling load on the heating,

ventilation and airconditioning (HVAC) system – and, in addition to efficient air-cooled chillers, contribute to 27% energy savings against the ASHRAE baseline.

The availability of alternative transport facilities, such as bicycle racks and a well-connected public transport network, encourages occupants to reduce their carbon footprint. The building occupants’ health and wellbeing is ensured with the use of low VOC coatings and a nearly 30% higher fresh air rate above the SANS guideline.

Lastly, resource efficiency is ensured by the use of local materials with a high recycled value, and zero-ODP refrigerant-based chillers achieve reduced emissions.

Gateway West is pursuing a gold rating for Leadership in Energy and Environmental Design (LEED) certification.

Each wing of the star-shaped building connects around the triple-volume central atrium, which also serves as the main entrance, creating a visual connection with the piazza.

Art house The Norval Foundation, a world-class art and cultural centre in the Steenberg area in Cape Town, was designed by dhk to strike a balance between protecting the artwork within and maximising the views of the natural landscape outside.

PHOTOGRAPHY DAVE SOUTHWOOD

T

he site of the Norval Foundation – on the slopes of the Constantiaberg Mountains, originally a farm dating back to the 17th century – is set against a backdrop of vineyards and a conservation area.

It was envisioned by the architects as a modern pavilion for art in this dramatic landscape.

It has been designed to turn its back to a neighbouring US consulate complex and nearby residential estates, so that the galleries and public spaces face the natural landscape. This enables the structure to capture framed views of the wetland, vineyards and mountains beyond.

The Norval Foundation is a pure expression of form.

It stands as a bold rectangular mass, delineating its heavy, walled enclosure and light, over-sailing roof. The materials palette is raw and honest, consisting primarily of pre-cast concrete, natural timber, granite and glass – thereby providing a contrast with the natural landscape.

Clerestory windows allow the roof to float above the heavy walls, like the lid of a box concealing treasures within, and allow soft, indirect, natural light to penetrate the interior spaces.

Externally, the pre-cast concrete is finished with a chamfered tartan grid, which draws the eye upwards and lengthways, and emphasises the scale of the building.

Internally, timber panelling is used to bring warmth to the spaces.

The building sits in an elevated position and shields the wetland, creating a private space for the sculpture park. In this way, it forms an inhabited threshold between public and private zones.

A triple-volume atrium establishes a deliberate visual connection between these zones – one urban, the other natural – and provides a physical transition between these contrasting environments.

One’s arrival at the Norval Foundation is experienced in a linear sequence. A curved wall that extends into the entrance court draws visitors past the double-volume restaurant and gallery shop, and into the generous reception area. This area directs guests to the central atrium and introduces the main galleries.

A terrace along the length of the building incorporates a timber deck serving the restaurant, and connects to walkways on either side that lead into the sculpture park.

The grounds also include an amphitheatre, a children’s playground and a picnic area.

The gallery spaces comprise a large, environmentally controlled exhibition space, as well as a series of six small galleries, culminating in a dramatic triple-volume sculpture gallery – an impressive setting for large-scale pieces, with Table Mountain as a backdrop.

All of the gallery spaces are column-free, allowing for maximum flexibility to display art in all its varied forms, so they can either be treated as separate experiences or create a sequential journey, as required.

The technical requirements for the gallery spaces take into account careful control of light, temperature, humidity, acoustics and fire prevention. To create the minimal spaces required for the display of art, all of the services are concealed in the wall and ceiling cavities for a seamless appearance.

The site has incorporated a sensitive existing wetland ecosystem that had been historically neglected. It is one of the last-known breeding sites of the Western Leopard Toad, an endangered species.

Concrete culverts were constructed underneath the road to allow for the toads’ safe passage, and the slope of the embankments were carefully designed to

allow the toads to traverse them. Earth ramps were also incorporated on the upper reaches of the estate to allow the toads to move easily to the breeding ponds.

The wetland and its surrounding buffer zones have been revived and replanted with locally indigenous fynbos, enhanced by other indigenous plants and naturalised species, and have already attracted a multitude of insects and birds onto the site.

T

he brief for City View House to Mellet & Human Architects was for a modern, functional and energy-efficient home, incorporating in its design the footprint of a demolished house on the site.

The property is situated against a north-sloping hill in the established suburb of Groenkloof, Pretoria.

The large, steep stand affords views over the city to the north, and borders a nature reserve to the south. Naturally, the client wanted both aspects to be incorporated in the design.

Groenkloof is a sought-after suburb, thanks to its moderate climate, established character, vegetation and central location. Older homes, most of them built in the 1960s and ’70s, have been bought by a younger generation and either changed or demolished to make way for homes better suited to a modern lifestyle.

“The challenge in architecture is to provide a solution to the client’s requirements that is functional, aesthetically pleasing and within the merits of good architecture,” explains André Mellet. “In our designs, we always keep in mind that the experience of architecture should be a journey of discovery.”

City View House is approached from the north along a steep driveway. The nature reserve lies ahead and a northern view of the house is provided. A parking area is reached, passing the house on the east through a narrow alleyway, but the visitor is not yet aware of the view behind. The foyer is entered and, moving to the right, the ground floor living areas open up and the spectacular view is exposed.

PRO J EC T #3 CIT Y VI EW H OUSE

“Using the original footprint was ideal,” says Mellet.

“The house is positioned at the highest point of the property, providing unobstructed northern views. In order to provide accommodation requirements another floor was added, creating the opportunity to visually link the first floor with the nature reserve on the south.”

The total floor area of the house is 590m2, with the ground floor accommodating the main open-plan living areas, as well as the guest bedroom and study. A glass sheet of sliding doors links the view and extends the interior onto a covered patio, pool deck and boma.

Ascending the staircase to the upper level, a corner window at the staircase gives a glimpse of the nature reserve. The first floor features three en-suite bedrooms and a TV lounge, while sliding doors provide these rooms with northern views. A south passage linking the rooms houses a collection of books, and a strip window above the shelves makes one aware of the nature reserve.

The central TV lounge separates the main bedroom from the other two bedrooms, and a low wall separates the main bedroom sleeping area from the bathroom, creating an open-plan effect and affording views even from the bathroom.

The lower ground floor is totally separate and private from the main house, and has access to the external areas. It can function as a self-contained flat, but is currently used by the owner as a hobby room and to house a collection of South African memorabilia.

Top The house has been elegantly decorated with furniture that complements the tropical modernist inspiration of its architecture.

Above The concrete frame of the house is used to collect rainwater, which is diverted into two galvanized rainwater tanks around the house, and below the pool deck.

The design offers the modern, functional living the client required, while also incorporating sustainable initiatives. The building has optimal north-south orientation; the walls, floors and roof are insulated; and double glazing was specified on the doors and windows.

“Our fondness for Brazilian architecture inspired the aesthetics of the house,” explains Mellet. “Externally, an exposed concrete frame is a feature of the north elevation. It acts as an architectural feature and is structural, while also providing sun control. Its extension to the west creates the covered patio next to the pool.”

This concrete frame collects rainwater from the Chromadek and diverts the water to galvanised rainwater tanks. These rainwater tanks are expressed as architectural features around the house, and below the pool deck.

Solar power is provided through an Icon Home Energy Hub, sufficient to support all the home’s

Hermanus’s Greenest Hotel When the owners of Schulphoek House, a small luxurious hotel in Hermanus, decided to expand their building, they integrated solar, water and cooling systems and employed green building materials in a pioneering exercise in sustainable building.

W

hen Schulphoek House in Sandbaai, Hermanus, was originally built 20 years ago as a seven-room guest house, it featured a number of forward-looking energy-and waterefficient features, including tanks for rain-water harvesting, solar geysers and cellulose fibre insulation.

Last year, when the owners – the Gutstadt family, who also own the Culinary Equipment Company which designs professional kitchens for restaurants and hotels – decided to undertake a major renovation, they once again set about pushing the envelope, with the vision of creating a carbon-neutral, bio-dynamic retreat without compromising on luxury or comfort.

The Culinary Equipment Company employs in-house architects and designers who worked with Wehrner Gutstadt on the design of the

expanded hotel, adding new seafacing rooms that double its capacity to 15 rooms, and enhancing existing rooms and common spaces. The beautiful sea-facing suites now offer what must be the lowest impact hotel experience in the coastal town.

After much research, they selected a construction method using thermally insulating wall and slab building panels from Futurehouse (www.futurehouse. co.za). This alternative building system comprises structural, prefabricated walling panels and slabs with an expanded polystyrene core.

They are encapsulated in high tensile steel galvanised wire mesh, which his finished with concrete applied with a gunite machine, making for fast, clean construction.

The meticulous insulation in the construction of the building is carried through to the roofs

and floors. The roofs have been triple insulated using 13mm ceiling boards with 100mm THERMGUARD cellulose fibre, an air gap and 40mm layer of woven mineral wool with a sheet of reflective aluminium foil on both sides. Floor insulation includes a 200 mm thick high-density polystyrene panel topped with a slab and screed. In conjunction, these materials provide not just thermal insulation, but acoustic insulation too, for an enhanced sense of privacy.

Double-glazed windows and doors by Fenster feature advanced German profile and hinge technology that allows the windows to seal perfectly and excludes temperature transfer when closed.

They can also swivel and tilt to let in the sounds of the sea while maintaining security without the need for burglar bars.

The efficiency of the building is carried through beyond its materials and construction to its operation, too. Water tanks – which have a capacity of 102 000 litres – provide water for garden irrigation and the swimming pool, saving an estimated 500 000 litres of municipal water a year.

The energy used for heating water for guests usually accounts for about half of a normal household’s electricity consumption. The technology at Schulphoek House from SEG Solar Energy works on the principle of storing heat rather than power in batteries.

Water is superheated using 12 high capacity solar panels, and stored in two 1500 litre fullyinsulated tanks. From there it is distributed throughout the hotel via a ring main, delivering virtually instantaneous hot water throughout the hotel without the need for a geyser. It also services creature

PRO J EC T # 4 SCH U LPH O E K H OUSE

comforts like heated towel rails.

The heating and cooling of the rooms and interiors is done with a hydronic air conditioning system that uses an inverter heat pump to heat or cool water, essentially drawing energy from the atmosphere. The water is stored in insulated tanks and circulated through a system that provides each room with its own radiator-like unit that heats or cools the air to the desired temperature in each individual room.

Each room also is also linked to an electronically controlled Lunos heat recovery ventilation system that provides fresh air, exchanging the air in each room three times an hour. It simultaneously harvests any difference in external and internal temperature and stores it within the unit for additional energy saving. In total, this system uses about as much electricity as one single ceiling down light.

The remaining power needs – lights, appliances and so on – are taken care of by a 10kW photovoltaic system with battery backup, which covers 90 percent of the hotel’s power usage. Extra unused power goes back into the grid, while municipal backup in case of emergencies is provided by just one three-phase connection. The energy savings of the low-energy LED lighting is further enhanced by motion sensor switches, the large windows not only let is the spectacular views, but maximise natural light, too.

Many of the technologies used at Schulphoek have been used either for the first time, or more

comprehensively than before in South Africa, and many of the suppliers consider the hotel a leading example of off-the-grid power efficiency in the country. It is a remarkable example of how an existing building can be integrated with the new, and upgraded using the most advanced technologies. Importantly, they’re integrated with a sophisticated computerised management system that helps all the component parts maximise their efficiency. The renovation at Schulphoek House is a pioneering project, pushing the limits of green construction and expanding its possibilities in its sector of the hospitality industry.

HOW TO PRESERVE TREATED TIMBER The natural durability of our commercially grown species, such as Pinus and Eucalyptus, is low, rendering them susceptible to insect and fungal attack. It is important to treat the timber with a wood preservative.

There are two types of wood preservation: primary (industrial) and secondary (DIY). In primary preservation, wood is impregnated (pressure treated) with an industrial chemical wood preservative e.g. CCA, TBTN-P, creosote, etc. This process increases the wood’s long-term durability and resistance to fungi and insect attack. Primary preservation is prescribed in South African National Standards (SANS), NRCS Compulsory Specifications and Building Regulations.

Secondary preservation is a surface application used for supplemental (preventative) and/ or remedial (corrective) purposes and applied by hand, e.g. treating previously untreated timber or exposed ends of machined pressure-treated timber.

Protective wood sealers or varnishes are not regarded as secondary preservatives unless

they contain active ingredients (biocide). Without active ingredients, such finishes merely protect against weathering i.e. moisture and UV rays, and not fungal and/or insect attack.

Primary preservation of timber is categorised into different Hazard or ‘H’ classes for different end-use applications.

When specifying pressuretreated timber, be sure to choose the correct H class for your intended application and apply remedial preservative to all cross-cut and exposed areas (except for cross-cut ends exposed in ground, fresh water

SIGNIFICANT SHIFT TO VRF-TYPE HVAC SYSTEMS IN KZN MARKET Tracey Jelf, the sales director of Fourways Airconditioning in KwaZulu-Natal (KZN), says: “Over the past few years, we have seen a significant shift towards commercial installations in terms of our sales of air conditioners, especially sales of our Samsung DVM units. We have a number of very large DVM installations taking place in the Durban and North Coast region right now, notably at Nedbank Park Square, Ocean Dune Sibaya and Pran Boulevard.”

Pran Boulevard Brett Kauffman of Dunair, which is handling the installation of the heating, ventilation and airconditioning system (HVAC) at Pran Boulevard, says: “There’s no doubt that consultants today are moving towards having energy efficiency in buildings.

‘Green’ is the buzzword, and it’s the reason that Samsung DVM is strongly on the up-and-up, thanks to its exceptional efficiency.

“At Pran Boulevard, we’re installing 22 DVM units outdoors, coupled with 137 MSP Duct units indoors.”

Ocean Dune Sibaya Craig Scott, the managing director of C.S. Airconditioning, agrees about the trend towards energy efficiency. “More and more consultants are requesting eco-friendly installations.

At Ocean Dune Sibaya, which has 260 luxury units, we’re installing a combination of 210 Free Joint Multi units and DVM Eco outdoor units linked

to more than 500 indoor units, predominantly 1 Way cassettes, with 44 studio apartments fitted out with the new 360º Cassette units.

“Part of the reason for this choice of Samsung is the level of back-up provided

by Fourways Airconditioning KZN. From our experience, the company outdoes all the competition in terms of providing support.”

Nedbank Park Square The R1bn Nedbank Park Square development will have a four-star Green Star Design rating and offer 40 000m2 of gross lettable area – of which 4 000m2 will be for retail usage and 36 000m2 for commercial usage.

Arup is the consultant and Luft Technik is handling the installation of 35 Samsung DVM outdoor units, coupled with 220 MSP Duct units indoors.

Says Jelf: “We at Fourways Airconditioning KZN place very strong emphasis on technical back-up for our dealers, with our staff always ready to go on site to assist with any queries.

Nuven Govender, our technical manager, has been in technical support for over 17 years and has done extensive training on DVM, RAC and systems.

He and his team are always on hand when our dealers require assistance.”

Kauffman concurs, saying: “Fourways KZN do indeed provide exceptional support.

Basically, they’re a big company but with that smallcompany friendliness and attention to detail.” www.fourwaysaircon.co.za

ENVIRONMENTALLY FRIENDLY HEATING SOLUTIONS Increasing numbers of people are taking into account the environmental effect of their lifestyle choices. One major decision is how to heat their homes in a manner friendly to the environment.

Electricity is often viewed by consumers as a clean fuel source.

However, most consumers do not live near power stations, where they can see the smoke billowing from the chimneys. Whilst we obtain the majority of our electricity from coal-fired power stations, it cannot be regarded as an environmentally friendly fuel or as a cheap power source.

Today’s savvy home owners are choosing to heat their homes using either a Closed Combustion Wood Stove (CCWS) or a flueless gas fire. Both these options provide large quantities of heat, capable of warming even the open-plan spaces typical of today’s architecture. They are highly efficient in their fuel economy and release almost no emissions into the atmosphere.

CCWSes are wood burning fires where the combustion takes place behind a pane of glass. Air is brought into the combustion chamber through easily adjustable air vents, allowing the rate of burn and hence the heat output to be controlled. A CCWS with a good insulating material inside it will increase the combustion temperature of the fire substantially, enabling heat to travel as fast across open-plan spaces as infra-red light. Assuming you are buying wood in bulk, CCWSes are capable of heating 150 to 200m2 of home for about R3 500 per winter.

With the high temperature combustion achieved in CCWS units, the emissions into the atmosphere are minimal. These units are actually rated worldwide as environmentally friendly, with the emissions produced being less than if the wood had been left to naturally rot in the forest.

Flue-less Gas Fires have taken over from the low heat output and high gas consumption Flued Gas Fires, which were so popular at the turn of the century. Flue-less Gas Fires are designed to burn the gas very cleanly, which enables them to operate safely without a chimney. With no heat losses up a chimney, these fires give three times the heat of a flued unit with the same gas consumption, making them ideal for warming large open-plan living spaces. And they give the convenience of heat at the flick of a switch, perfect for today’s busy consumers. www.infinitifires.co.za

GYPROC LOVES RHINOS There’s a constant need for business to increase its conservation efforts – this is Saint-Gobain’s philosophy, and it underpins the company’s rhino safety initiatives Last year, Saint-Gobain Gyproc South Africa announced a three-year sponsorship for SANParks Honorary Rangers, a group of passionate volunteers who work on projects in support of SANParks. The sponsorship is aimed at furthering efforts to protect rhinos and augmenting anti-poaching strategies.

Despite valiant efforts to stop the brutal slaughter of South Africa’s rhinos, the safety of the species is still very much in jeopardy. SaintGobain Gyproc is donating R1 million for three years, together with a percentage of sales from its RhinoBoard and RhinoLite products, thereby furthering its contribution to safeguarding the rhino population.

The proceeds from 2017, the first year of its sponsorship, went towards training and buying muchneeded equipment in the field for rangers, and to supporting the Air-wing and Veterinary

Wildlife Services of SANParks.

The second year of the sponsorship will continue the contribution along similar lines.

“We know that although the rhinoceros is a symbol of strength for today, it may be gone forever tomorrow.

That is why we want to make a difference,” says David Anderson, General Delegate and CEO of Saint-Gobain SubSaharan Africa.

“We hope that by supporting the SANParks Honorary Rangers and communicating the importance of its cause to our customers, we can add Saint-Gobain’s voice to conversations about rhino conservation in South Africa.”

For decades, the aim of World Environment Day has been to encourage worldwide awareness and action for the protection of the environment.

In support of this annual event, which takes place on 5 June, Anderson believes more private sector organisations should be

getting involved in local conservation and in directing funds towards preserving the environment – specifically, rhino anti-poaching efforts.

“As private businesses increasingly understand that investments in conservation can help to create opportunities, mitigate risk and protect business assets, environmentally friendly sponsorship opportunities are becoming a marketing imperative,” Anderson says.

The Department of Environmental Affairs released poaching statistics earlier this year, showing that 1 028 rhino were poached in 2017 – a slight decline of 26 animals from the previous year. Despite this very minor decrease, the fact

remains that nearly three rhinos are being killed every day.

Saint-Gobain Gyproc received an Appreciation Award at the 19th Kruger National Park Achievement Awards in recognition of its conservation efforts. This prestigious event took place in Skukuza on 18 May. To assist Saint-Gobain’s support of SANParks, consumers can purchase or specify any Saint-Gobain Gyproc RhinoBoard and RhinoLite product – look out for the SANParks Honorary Rangers endorsement logo to ensure that you’re buying an original product and contributing towards rhino conservation. www.saint-gobain-africa.com

PROPELAIR TOILETS USE 84% LESS WATER Water shortages and poor water quality are some of the challenges associated with climate change, increasing pressure on the world’s available fresh water supply.

One technology that may help is the air-flushing toilet from Propelair.

Propelair toilets are highperforming and offer a waterefficient solution that helps save water, money and energy.

The toilet only uses 1.5 litres per flush – 84% less than the South African standard – by accelerating the water with a blast of air. It is marketed wherever there is high water usage, such as in shopping centres, theatres, offices and hotels. The savings can pay for the toilet in as little as two years, depending on water

usage patterns.

The financial savings are useful to businesses and the public sector, naturally the first priority for water savings – and especially in drought-stricken places like Cape Town. This type of toilet can be retrofitted into a bathroom or planned for in new structures.

Unlike many add-on products and retrofitted water-saving devices that are unable to definitively prove their watersaving capabilities or work reliably flush after flush, the Propelair toilet was conceived from the outset to use as little water as possible which then could be retrofitted into the existing plumbing system.

There are a number of features that make it an improvement on what is found

40 LEADINGARCHITECTURE & DESIGN JUNE/JULY 2018

in many domestic applications.

For high usage areas, the toilet’s quick turnaround time, reduced bacteria spread from the closed flushing cycle and ease of maintenance are all factors that would contribute to an overall improved toilet experience.

How much water would it save? In South Africa, the average person uses 142 litres of water a day, 22% of which is on toilets. It’s the second biggest use of water after showers and baths at 25%.

That could make a considerable difference if South Africa starts to experience more droughts in future.

By installing a Propelair toilet, you will be improving your company’s carbon footprint and environmental performance, as well

as demonstrating your company’s commitment towards sustainability and the environment.

Burgess & Partners Plumbing Services are exclusively involved in the supply, installation and maintenance of Propelair toilets in South Africa. www.burgessplumbing.co.za

GEBERIT RIMFREE TOILETS – PERFECTLY CLEAN, EVEN WITHOUT SPECIAL CLEANERS

Geberit has set itself the goal of making bathroom cleaning as easy as possible. Following on from prewall installations with wall-hung WCs, Rimfree WC ceramic appliances are the next step in this direction.

Because Geberit WC ceramic appliances dispense without a flush rim, they don’t have any corners and edges that are difficult to access.

The undesirable rim Traditional WC ceramic appliances have a flush rim, which is designed to guide the water during the flushing process. However, while it is practical for flushing out the toilet, it is awkward to clean.

Only special toilet brushes or skilled hands manage to get underneath the rim.

It is also very difficult to tell whether, and when, cleaning is required. Despite water regularly flowing underneath the flush rim, limescale and dirt build up there, and this can become a hygiene issue.

You can quickly modernise your bathroom with a Rimfree toilet at a reasonable price, without having to renovate the bathroom or build a new one from scratch. The connections,

from the position of the hanger bolts right through to the flush and outlet pipe, are standardised and thus identical for all toilets. All that needs to be replaced is the WC ceramic appliance – much to the delight of the plumber and the customer.

Rimfree is better For this reason, many manufacturers of WC ceramic appliances took a closer look at the design of the toilet pan.

The goal was clear: minimising the flush rim while at the same time achieving a good flushing-out performance.

This is a goal that Geberit also championed.

Geberit Rimfree has systematically thought this development through to the end. The Rimfree toilet is entirely without a rim.

No flush rim, no apron or open notch. This means that there are no longer any hard-to-reach places and the smallest speck of dirt is immediately noticeable. The flush technology works with a patented flush guide that guarantees optimal flushing and perfect results even with low water volumes.

Free yourself The Geberit Rimfree technology dispenses with annoying cleaning and the need to use expensive, outdated special cleaning agents. A Rimfree toilet is considerably easier to clean because it does not have a flush rim, under which dirt and limescale deposits can accumulate and cause unpleasant odours to develop.

A Rimfree toilet therefore fits perfectly with modern bathrooms and contemporary lifestyles. Just a single wipe and the toilet is sparkling clean once again, which means that you no longer need any special cleaning agents or brushes.

The technology behind it This is possible thanks to the Geberit flush technology, which guides the water in its intended path before it enters the WC ceramic appliance, not afterwards.

A patented flush guide represents the core element of the Geberit Rimfree technology.

This flush guide is designed in such a way that it guides the water to exactly where it is needed for a clean flushing out – and nowhere else.

It flushes out the WC ceramic appliance thoroughly and uses valuable drinking water in an efficient and resource-saving manner. www.geberit.co.za

THE ONE AND ONLY INSTANT-GRIP DEN BRAVEN HIGH TACK – TRIED AND TESTED A facilities management workshop was recently held at Den Braven’s head office for customers involved in the maintenance of shopping centres, hotels and offices.

It comprised a hands-on demonstration, and attendees learned many “tricks of the trade” – from application techniques to choosing the most suitable Den Braven sealant or adhesive for a particular job.

To demonstrate the unmatched capabilities of Den Braven High Tack, it was applied to an 18kg brick, which was then positioned on top of another 18kg brick.

The audience watched in awe as the top bonded brick was immediately lifted off the ground, with the bottom brick stuck fast – demonstrating the incredible instant-grip capabilities of High Tack.

A steel trowel was then bonded onto a brick using High Tack. Again, the trowel and brick were lifted immediately and held up for all to see how instant the bond is between different substrates.

Instant-grip Den Braven High Tack can be used without mechanical support for bonding panels, skirting boards, windowsills, natural stone, thresholds, isolating materials and metal connecting joints. It is free of isocyanates, solvents and silicones, is neutral curing and is almost odourless – in line with standards set by the Green Building Council of South Africa. www.denbraven.co.za

To help home owners and everyday South Africans bring international flair into their homes, ISCA – South Africa’s trendiest brand of quality kitchen and bathroom fittings – shares some insights into the latest and most exciting interior trends that are expected to take shape this year. It’s all about tap courture, and there are two key trends this season: Indulged and Grounded.

Indulged is all about modern luxury brought to life through a touch of extravagance. It includes the following elements: Moody colours Dramatic colours come into play in the home, with shadowy but sophisticated shades of black making a more prominent appearance, as well as dusty blush pinks and rustic golds. These colours are a great way to add intensity and boldness to a room.

Deliciously indulgent textures From soft velvet to plush woven textiles, this trend is all about the feel of a décor item and can easily translate into soft-feel scatter cushions in a range of dusty, dark colours, or even a faux fur throw for the bedroom.

Curated collections All-white interiors and minimal décor are a thing of the past, with international trends showing that people are using their living spaces and decorative abilities to express their personalities with shelf space and countertops filled with items that create a kind of personal ‘exhibition’ of unique items.

Grounded talks to the natural elements of the earth using materials that are raw and refined. These include: Straight from the earth Upcoming seasons will see home owners using less perfectly sculpted, polished design and more rustic, natural aesthetics that relate to the material’s natural form, such as burnished metallic elements paired with chunky woven fabrics.

Bringing the earth inside Homes are being transformed into tranquil indoor gardens to create a more natural and relaxing aesthetic.

Elegant utilitarian design is central to this trend, which can also be conveyed through plants and greenery. www.isca.co.za

HANSGROHE: ADDING VALUE THAT MATTERS As you enter a hotel room, the first thing you usually see are the bed and the size of the room. Your shower is hidden away behind the bathroom door and is often overlooked.

What is often not considered is the fact that after a long day of work or sightseeing, your first moment of relaxation is taking a proper shower and then heading for bed.

Recent surveys conducted by various hotels have shown that the most important elements for travellers are: • A comfortable bed and pillow • Free and fast WiFi • A great performing shower • A big TV screen When supplying showers and mixers to a hotel, Hansgrohe not only promises good quality, but also long-term value, award-winning innovation and design, outstanding service and premium features – fully

understanding the importance of a proper shower.

Hansgrohe is currently ranked sixth globally on the iF Design Awards – above world-renowned brands like Audi, BMW and Apple. The company is an industry leader not only for its designs, but also for its innovative technologies such as SelectButton to improve ease of use, the iBox universal, which makes installation and renovation quicker and easier, and its EcoSmart technology, which uses up to 60% less water – to name just a few.

To top it off, Hansgrohe’s service is world-class, covering everything from project consultation, bathroom planning and on-site service to maintenance tips to ensure that your investment in showers and mixers is a long-term one. www.hansgrohe.co.za

ENVELOPED BY NATURE’S WARMTH One would think it impossible to take something strong and naturally beautiful and make it better – yet Dado has.

Dado baths and basins are manufactured from Dado Quartz, which is formulated by combining finely crushed quartz mined from southern Africa with a resilient resin. The final result is a silky smooth and brilliant white bath.

Dado strives to provide a range of styles for a global market.

To this end, it has extended its existing range to include the Claire and the Nova Ovalo free-standing baths.

As you soak in the bath, you can enjoy the smooth surface under your skin that is hand finished. The quartz is both hygienic and maintains the heat for longer.

Both baths are equilaterally shaped, with slim sides that taper towards their generous base. The high sides envelop the warmth even further around you.

The Nova Ovalo bath has a matching basin with slim sides in order to complete the luxurious appeal of your bathroom space. This bath is also available in either a matt or a gloss finish and measures 1 760 x 820mm – quite high sides to give bathers the feeling of being enveloped by a warm cocoon.

The Claire bath measures 1 660 x 700 x 535mm, which is perhaps slightly smaller than most free-standing stone baths. This may then fit into a more modern, compact space. The bath is available in a matt or gloss finish. www.italtile.co.za

SHARP-EDGED FARMHOUSE This farmhouse in the countryside in Galway, Ireland, by Ryan W. Kennihan Architects, takes its starting point from the vernacular Irish farmhouse typology, which exists throughout the surrounding landscape.

While the design adopts the simple volumes and courtyardbased organisation of this robust and useful typology, it evolves a new, expressive tectonic language.

Its distinctive roofline rises from the green fields of the countryside setting.

A slate-look roof, white limewashed walls and a rough-cast concrete finish reflect the rural character of its surroundings.

Here the traditional ring beam

is exposed and incorporates other functions, such as water collection and lateral thrust resistance – allowing for an open, unbraced timber roof.

Kennihan used Marley Roofing’s Alterna Fibre Cement Slates for the roof covering. “Even if the budget permitted, I wouldn’t have used natural slates. Fibre cement suits the outline of the form and makes it sharp, knifeedged,” he says.

The traditional south-facing, sheltered courtyard is lined with a shallow colonnade, connecting inside and out through a deep threshhold and taking advantage of the low– angle, passive solar gain. www.rwka.com

A.B.E. WATERPROOFING FOR NEW INNOVATION HUB BUILDING IN BOTSWANA a.b.e. Construction Chemicals has supplied large volumes of polyurea coating for the waterproofing of an expansive roof of one of the new buildings of Botswana’s massive Innovation Hub campus in Gaborone.

Noel Abendroth, the manager of a.b.e.

High Performance Coatings Solutions, says VIP QuickSeal PP350, a pure polyurea that offers exceptionally high tensile strength, was applied on the 26 000m2 concrete roof of one of the buildings that form part of the “iconic symbol of Botswana’s support for research and development, as well as the promotion of innovation and entrepreneurship”. a.b.e. Construction Chemicals is part of the Chryso Southern Africa Group. It holds an exclusive agreement with VIP (Voelkel Industrie Produkte) in Germany for the sale and distribution of the company’s respected range of protective coatings and joint fillers in southern Africa.

The waterproofing of the roof will accommodate one of Innovation Hub’s characteristic roof gardens. Initially, the job was handled by Hiremore Civils from Botswana and later, by a.b.e.’s approved applicator, Diamond Linings.

The Botswana Development

Corporation’s Innovation Hub was designed by SHoP Architects of New York, after the firm won an international competition to design the campus.

The complex features a collection of long, slender buildings that reach out into the open land and are covered with a concept that SHoP calls an “Energy Blanket” roofscape, which incorporates sustainable energy techniques.

Large overhangs passively shade the buildings’ interiors, while the roofs collect rainwater for re-use and are covered by roof gardens with indigenous species.

Recently launched locally, VIP’s QuickSeal PP350 is a spray-applied, instant curing, flexible membrane that can be built to any thickness in one application, in virtually all environmental conditions. Very cold, very hot or even very humid environments do not affect the curing time or physical performance of VIP QuickSeal PP350.

“VIP QuickSeal PP350 provides

flexible, seamless, hard-wearing substrate protection for a wide range of substrates,” says Abendroth. “Its rapid spray application and instant curing characteristics enable shorter shutdown times than traditional glue.”

Among the product’s features are: • Extremely fast application time • Tack-free in seconds – it can even be walked on within minutes • High elongation at break • No need for protector boards during back filling • High abrasion resistance and excellent thermal stability. www.abe.co.za

SUCCESSFUL STRUCTURAL STEEL WAREHOUSE PROJECT IN KZN The Pepkor Warehouse in Hammarsdale, KwaZulu-Natal, serves as a distribution centre for the Pepkor group. The building is roofed and clad with a high-tech, premium grade of coated steel that provides not only long life in service, but also an attractive finish.

The building features the innovative use of steel on many levels. As GD Joubert, senior associate at structural engineers EDS Engineering Services, says: “The brief called for approximately 17.35m clear height to underside of eaves. The construction materials consisted of reinforced concrete and structural steel made according to EDS Engineering Services’ design, with appropriate corrosion protection where necessary.

“It was envisaged from the outset that the warehouse would be constructed largely of structural steel. The main support columns of the warehouse are concrete up to 12.6m and 17m from finish floor level. The remainder of the structure was constructed from structural steel. Structural steel was strengthened locally to allow for the installation of solar panels to a roof area of about 15 000m2.

Roof type “The structural system used for the building was based on a girder truss system, carrying lateral trusses, which makes up the main elements of the roof. Various steel profiles were used for the building, including the structural, roofing and cladding elements,” says Joubert.

According to Dave Reid, general manager at Macsteel, the project was completed with Macsteel’s Novotexi 440 concealedfix roofing profile using BlueScope’s legendary ZINCALUME ® steel in coating mass AZ150 and total coated thickness (TCT) 0.53mm on the roof.

The cladding was the company’s Wide-span 762, formed using Clean COLORBOND coating mass AZ150 at 0,47mm TCT on the sides.

“Significantly, Macsteel roll-formed 660 tons on site with its

54 LEADINGARCHITECTURE & DESIGN JUNE/JULY 2018

mobile roll-forming machines in record time,” says Reid.

According to Arno Hanekom, regional manager of BlueScope Southern Africa, a critical element to the design of the roof was the selection of ZINCALUME and Clean COLORBOND steels.

“The coating on ZINCALUME comprises 55% aluminum, 43.5% zinc and 1.5% silicon. It has excellent corrosion performance and forming capabilities, and is available in high strength grades.

“In the case of the Pepkor DC, product was supplied in coating mass AZ150, TCT 0,53mm and at longitudinal tensile strength G550. In addition, ZINCALUME offers an above-average solar reflective index when compared with other unpainted roofing materials such as galvanised steel.

“The continuous hot dip process used to produce ZINCALUME steel provides a surface coating which has a shiny appearance with a uniform small spangle. This coating, patented to BlueScope, determines the solar absorptance of the upper surface. In short, ZINCALUME steel minimises the fraction of the sun’s energy absorbed by the roof and maximises the fraction reflected.

“With a new SRI value of 63, ZINCALUME offers superior performance over time when compared to all other unpainted materials. It keeps this property much longer than comparable materials and is not prone to corrosion, even in a harsh climate.”

Shades of grey cladding The warehouse’s cladding was erected by Impact Engineering.

Clean COLORBOND was supplied in coating mass AZ150, TCT 0,47mm and at longitudinal tensile strength G550. Colours were Armour Grey and Volcanic Grey, used to keyline prominent structural elements on the side of the building in a visually pleasing way.

In addition, the high-performance paint system on Clean COLORBOND incorporates various sustainability and long-life features, including our well-known Thermatech coating system. www.bluescope.co.za

PRACTICAL PHYSICAL ACCESS SECURITY SOLUTIONS FROM TRELLIDOR Trellidor manufactures several different entry-door security solutions to protect commercial premises.

Retractable trellis-style gates Trellidor Retractable sliding security gates are frequently specified for commercial premises that need to be protected from theft of merchandise, or to prevent people from getting into restricted areas. Examples include cigarette counters in fuel station shops and pharmacies that need to protect their prescription medicine stores.

These gates can be fabricated to suit any entrydoor shape, from revolving to pivot to double doors. They can also be powder coated to complement contemporary colour preferences.

Trellidor Retractable security gates are available in several models with differing hi-tech strength features, including a

number of designs that carry international certification for strength under attack.

Modern technology has been incorporated in the manufacturing process, so that the gates operate smoothly, stack neatly to the side when open and are fitted with patented locking systems.

Wall pockets can be designed in collaboration with your Trellidor supplier so that the gates are stacked and hidden out of sight during opening hours.

Aluminium roller shutters Trellidor Rollerstyle aluminium shutters are light and easy to operate, but are strong enough to lock down commercial premises. They make ideal entrydoor protective barriers because they don’t require a bottom track, which is often a tripping hazard to pedestrians.

They roll up completely into a compact, discrete shutter box, leaving the entrance completely clear. The shutter

box can be hidden in a wall or ceiling cavity if the building design caters for this.

These roller shutters can be fully automated and remotecontrolled, which is especially convenient when incorporated into a centrally controlled building management system.

Security screens Beautifully designed buildings with great architectural style are often left unsecured so as not to detract from their attractive features. Concerns for the occupants’ safety should not be ignored, however,

and Trellidor Clear Guard security screens are a very workable solution.

These protective screens are custom designed to match the operation of the entry door without interfering with the door’s handle and locks.

The bulk of each barrier is made up of a see-through mesh panel, encased in a sleek aluminium frame.

Trellidor Clear Guard protects the entry door without detracting from its design, and offers benefits such as blocking out mosquitoes and monkeys. www.trellidor.co.za

ACCESS CONTROL RADAR SYSTEM IDEAL FOR RETRO-FITTING Flow Systems has introduced a new, barrier-free access control radar system to the market. The system is a combination of interconnected electronic door locks, ceiling-mounted stereo cameras, sophisticated software and motion detectors that can be retro-fitted into a commonly configured building reception area or lobby.

Access control radar is designed to work with the most customary door control configuration: a pre-existing, externally mounted entry control card or fingerprint reader or PIN unit adjacent to the locked outside single or double door. The adaptive FSC Radar system requires no extensive door, wall or ceiling alterations and is resistant to sunlight, glass and mirrors.

At the heart of the FSC Radar system

is its unique, patented technology that admits only one person into a restricted area per valid authorisation by tagging, and tracks the person within the scanning zone, thus eliminating the security risks of piggybacking and tailgating.

The FSC Radar software accepts data from virtually any badge or access system, including biometric and smart ID systems, card readers or PIN pads. FSC Radar controls the electromechanical door locks so that when any one door is open, all other doors of the security area are automatically locked. Benefits of radar: • Adapts to existing buildings and can be integrated into an existing reception, lobby or interior room • Simple to install – no civil works such as the digging up of expensive flooring

56 LEADINGARCHITECTURE & DESIGN JUNE/JULY 2018

• Seamless incorporation into existing building security systems • Low or no maintenance – the system has no motors, gearboxes or moving parts to wear out or break • No special lighting required. Overhead office level of 300 lux is sufficient, and the system is unaffected by full ambient light from outside • Allows mixed traffic. Can be used as an entry and egress point for both pedestrians and carts, without the need for special staging areas on the floor • Allows free egress from the building by multiple persons at the same time • Is a stand-alone system requiring no central monitoring, control or management. www.flowsystems.co.za

SWARTLAND AND SUSTAINABILITY Going green is no longer just a fad; it’s a reality that individuals and companies alike need to work towards in order to attain long-term sustainability for our future.

Leading timber and aluminium window and door manufacturer Swartland is one such company.

Swartland is committed to developing wooden and aluminum products and practices that reflect its vision to make a positive difference to people and the planet.

Swartland’s Cobus Lourens shares his insights into how this forward-thinking company is making headway when it comes to the sustainability of our natural resources.

Global Reporting Initiative for sustainability reporting Swartland incorporates some of the world’s best standards and practices in operations.

In line with this vision, the company has embarked on a GRI Sustainability Reporting Process with the aim of increasing communication with stakeholders about transparency and accountability. Says Lourens: “Our sustainability reports contain key information in an easy-to-read format, so as to provide all stakeholders with the information that they require, whilst driving us towards improvement in all key areas of the business.”

Among other things, the report demonstrates Swartland’s vision to become a shining example of sustainability stewardship. “At Swartland we aim to grow the company whilst reducing the relative consumption of natural resources, thereby advocating and activating sustainable business practices in everything

that we do. We are aware that our own business sustainability is directly linked to the sustainability of our planet and its people. It is just a matter of time until all organisations come to the same realisation,” says Lourens.

Fresh from the oven Over a year ago, Swartland invested in four new high-tech, computer-controlled kilns that have allowed the company to dramatically increase the amount of timber that can be kiln-dried during any single drying cycle, without compromising on the wood’s optimal moisture content. This process reduces the chances of the wood contracting after production, which in turn improves the quality, stability, durability and performance of the end product.

Every aspect of these kilns has been designed to be as energy efficient as possible.

“What makes these kilns so unique is their ability to achieve best-in-market energy efficiency through a built-in intelligent energy management system. For example, the system can make small fan adjustments in order to reduce power usage during peak periods, and it considers the energy available from on-site heating plants,” explains Lourens.

58 LEADINGARCHITECTURE & DESIGN JUNE/JULY 2018

The kilns also boast eco vents that recycle the heat that’s generated during the drying process, reducing the amount of fuel burned and CO2 emissions given off. Up to 50% of the water utilised is also recovered and re-used, making the entire process much more water efficient.

In addition, the motors and electronics have been positioned on the outside of each unit so they aren’t exposed to excessive humidity and heat, which serves to increase the kiln’s lifespan and, in so doing, decrease the overall carbon footprint.

Says Lourens: “Swartland’s new kilns are a prime example of the company’s commitment to be as environmentally responsible as possible, making a positive difference to the planet.”

Coming full cycle Swartland is committed to reducing waste. One of the ways it achieves this is through its recycling programme.

Says Lourens: “There are many green benefits when using wood as a construction material, such as the fact that timber is easily re-used, recycled or broken down into compost after use.”

As a start, Swartland uses the best woodcuts from trees

to create the finest quality windows and doors. Other grade cuts are used in wood laminate products, and that which does not get used in production, such as excess wood chips, is used to fuel boilers that kiln-dry the wood.

In addition, shavings and sawdust are sold on to local farmers for chicken bedding.

“Virtually nothing is wasted,” says Lourens, adding: “Our ‘think long term’ philosophy guides us at Swartland in everything we do – not just with regard to the materials we choose to use, but also with the manufacturing process, and the way the company is run. Our commitment to increased energy efficiency and environmental sustainability is deeply ingrained. It may cost Swartland more to produce a green product, but if it means giving back to the environment, then it’s a cost we encourage.”

Green building regulations The current state of the urban environments we inhabit is cause to be more environmentally conscious – from the food we eat to the cars we drive, and right down to the windows and doors we choose for our homes.

And Swartland is leading the pack when it comes to going green. “All the products in Swartland’s KENZO range of aluminium windows and doors, as well as its range of Ready2-Fit timber wooden windows and doors, are SANS 613- and SANS 204-compliant – which means that not only do they comply with all the necessary local building regulations, but they are also an environmentally responsible choice,” concludes Lourens. www.swartland.co.za

BEER IN WINE COUNTRY The interior design of Franschhoek Beer Co’s new restaurant, Tap | Eat, balances indoors and out, the natural and the luxurious Ringed by oak trees and green lawns, Tap | Eat enables beer lovers to experience the clean air and dazzling vistas of the mountainous Franschhoek district, while enjoying a brew and a bite. Eating in style while appreciating the outdoors was one of the primary goals of interior design company Inhouse when creating Franschhoek Beer Co’s new foodie destination.

Stacking glass doors allow sunlight to flood the interior and serve to bridge the indoor and outdoor seating areas. A number of views can be enjoyed, from the distant mountains to the immediate landscaping or even the restaurant’s detailed interior design.

SIKA’S CONCRETE REPAIR AND PROTECTION PRODUCTS USED FOR CORNELIS RIVER DAM REFURBISHMENT The Phumelela Local Municipality in the Free State is currently experiencing severe water shortages. As a result, it is considering options to ensure the provision of a sufficient and sustainable potable water system for the future, for the short and longer term. Water usage has been restricted, but the water quality deteriorates on a daily basis.

The high numbers of people migrating from rural to urban areas, along with the changing patterns of water usage – mainly as a result of the introduction of waterborne sewerage systems under the bucket eradication programme – have placed additional stress on existing infrastructure and resources.

The final objective of this project is to implement a sustainable regional bulkwater supply scheme in the Phumelela local municipal area, prioritising Warden.

The Cornelis River Dam – situated in the Free State between Johannesburg and Durban, 56km north of Harrismith – has undergone major refurbishment. The project commenced in June 2017 by contractors Raubex.

Sika’s reputable range of concrete repair and protection products were the top choice of specified products by project managers Rudnat Projects CC. BHM Readymix from Harrismith supplied all the concrete with SikaPlast V220 and Stallion 2 admixtures.

In order to grout the anchor rods into the rock before pouring the concrete, Intraplast-Z was used to create the steps. This is a grout admixture, designed to introduce micro bubbles into the

grout mix, creating wet volume expansion, and to increase fluidity without segregation.

As a curing agent to prevent premature water loss, Sika’s Antisol E was sprayed on areas of mass concrete.

Forming a thin film barrier, this ready-to-use, liquidcuring compound does not disturb the normal setting action of concrete, which is then allowed to cure and achieve maximum properties.

Separol-GU, an oil-based release agent, was used to provide easy release properties to the formwork and a high-quality surface finish to the dam wall. Sika micro fibres were specified to be used in the spillway concrete, as well as in the concrete mix of the dam wall, to reduce any crack tendencies in early-age concrete.

The structure was primed with Sikagard-550 W Primer prior to the application of Sikagard-550 W Elastic, an acrylic-based emulsion and a high-build, protective coating which provides a durable covering with excellent resistance to weathering.

As a surface hardener for concrete, Sikafloor

CureHard-24 was used in the spillway concrete. This easyto-apply compound reduces dusting of concrete floors and improves chemical and abrasion resistance, compared to untreated concrete.

The concrete wall was repaired using Sika MonoTop-610, an easy-toapply cementitious, polymermodified, one-component slurry. This high-quality primer provides excellent bond for Sika MonoTop-612, a high-strength repair mortar containing silica fume and synthetic fibre reinforcement. Providing excellent slump resistance, it is particularly suitable for application on overhead and vertical surfaces.

Sika Waterbar Type O-20 was centrally placed in all the expansion joints. It’s manufactured from virgin thermoplastic PVC for strength and flexibility, and for easy on-site welding. Internationally tested Sika-Waterbars were used to seal construction and expansion joints in all waterretaining structures. They were designed to withstand high water pressure and were supplied in rolls of various

widths and types.

Sika Plast Stallion-2 and Sika Plast V220 were used as admixtures for the structural concrete and blinding concrete, as multipurpose water reducers and as superplasticisers, with the aid of Sika’s ViscoCrete polycarboxylate polymer technology. Its higher ultimate strengths allow for greater engineering design, flexibility and structural economies.

There were two main challenges during this project.

Firstly, it was necessary to drill 21m into the ground and create a grout wall before starting with the actual wall because water kept rising when drilling into the ground. Drilling into the rock for the anchor rods was the other challenge because the rock was so hard and had caused the drill bit to break off or go blunt.

Regardless of these challenges, it is expected that this project will be completed in 18 months. The aim of the project was to refurbish 5 000m2 of concrete.

However, it is assumed that the area will increase on completion of the project. www.sika.co.za

LOTEX MAGBOARD NOW AVAILABLE FROM NLA Lotex Magboard is a fire-proof, thermal insulation building material. It is commonly used in dry construction in a number of applications, including wall and ceiling linings, exterior cladding, fascias, tile backing and flooring underlay.

Magnesium Oxide board, a mineral bonded cement also known as MGO, is a type of sheathing board similar to gypsum and cement fibre board. It comes in sheets up to twice as large as gypsum boards, yet it weighs just half of what cement fibre boards weigh. It is also water resistant, unlike plywood and gypsum boards.

In addition, MGO is fire and heat resistant, and resistant to mould and mildew. It is flexible, absorbs sound, and is paintable and toxin-free.

Lotex Magboard enables lightweight designs of roofs and floors, and its acoustic capabilities provide alternative material for ceilings. This material can also replace concrete and steel constructions for roofing and can help achieve thinner layers in fire-resistant construction than traditional materials.

Because of its versatility and numerous advantageous characteristics, Lotex Magboard is not only used

extensively in the building and construction industry, but can also be used in sound studios, schools, movie theatres and shopping centres, as well as for partitioning in boats, busses and trains.

Lotex Magboard is available in various thicknesses and board sizes. MGO board can absorb moisture, but its performance and integrity remain unaffected, so it can be used indoors or outdoors and in damp locations such as bathrooms.

MOISTURE RESISTANCE Lotex Magboard retains its dimensional stability and integrity in damp and humid conditions. Therefore, it can be installed and used at the early stage of any construction project.

FIRE PERFORMANCE Lotex Magboard is noncombustible and can be used in any area or application where a fire-resistant function is required.

SOUND ABSORPTION Lotex Magboard has excellent sound absorption capabilities – a wall constructed with four layers of 12mm Magboard has the same soundproof effect as a 150mm solid brick wall.

66 LEADINGARCHITECTURE & DESIGN JUNE/JULY 2018

BIOLOGICAL AND CHEMICAL RESISTANCE Lotex Magboard is resistant to rodent and insect attack, as well as to mould growth and most chemicals.

ELECTROMAGNETIC WAVES PREVENTION & ANTI-STATIC Lotex Magboard is suitable for applications where

electromagnetic wave interception and static electricity prevention are required. This includes areas such as operating theatres, X-ray facilities, laboratories, electronic component assembly areas, or any area requiring the reduction of electromagnetic waves and anti-static environments. www.nla-timbers.co.za

CHRYSO SEES NEW HOPE, DESPITE EXCESS CEMENT CAPACITY AND COMPETITIVE CONDITIONS South Africa’s new political leadership has rekindled a sense of optimism within the South African construction industry.

However, the wounds of excess capacity still fester, says Norman Seymore, CEO of the Chryso South Africa Group and vice-president of Chryso globally.

Chryso SA is the parent company of a.b.e. Construction Chemicals.

Seymore says although Cyril Ramaphosa has only recently taken over the presidency, and that the land expropriation issue could still pose challenges for the ANC-led government, the local construction industry now seems to have a sense of “cautious optimism” about its future.

“There is the expectation that longdelayed infrastructural projects – which were budgeted for many years ago – could finally be given the go-ahead to provide more work in the building and ancillary sectors. Chryso is, in fact, already seeing an upsurge in building activity. There’s increasing demand for our products particularly in the Western Cape, where water conservation will spawn several urgent and major building projects. There’s also demand for renewable energy projects in the Eastern Cape and for upgrading the Transkei region’s infrastructure, to name just three examples.

“The industry is now also more confident that the long-term promise contained in the National Development Plan will now gradually be fulfilled.”

But, adds Seymore, the damage done by the cement industry’s excess capacity is by no means over, particularly in the ready-mix concrete sector, which is currently facing very difficult trading conditions. “Excess capacity and depressed trading conditions have swept ready-mix producers into a ‘price war’, caused by the proliferation of players in the

Architects

market and the fact that users of ready mix are operating in a do-or-die market, where pricing rules.

“Adverse operating conditions in the ready-mix sector impact negatively on Chryso as the industry is an important market for our group’s products.”

Given such difficult local conditions, along with the weakening of the rand, Seymore feels Chryso’s decision to seek new markets elsewhere in Africa has been fully justified. And, to expand the group’s export drive even faster, he has personally taken over responsibility for driving exports to sub-Saharan Africa.

New Chryso/a.b.e. distributors have been appointed in Botswana and Mozambique, with more to follow in other African countries such as Angola, the Democratic Republic of the Congo, Tanzania and Uganda. Chryso established its own East African operations, based in Nairobi, two years ago.

“Chryso’s other priority for future growth is new products, and here the group intends widening its offerings in decorative concrete, structural fibres, waterproofing, environmentally friendly dust-suppressant products, and our product range for the mining sector.”

The opening of Chryso’s Centre of Excellence testing laboratory and research facilities at the group’s local head office in Jet Park has also paid dividends. The new centre features ultra-modern testing equipment and temperature control systems to offer cement, concrete and construction technology as an added-value service to customers.

“The centre provides tailormade solutions to match specific applications and customer requirements, and recommends suitable additives and dosages to boost concrete mix performance and contain costs,” says Seymore.

“The new facility – which complements the work done by accredited testing laboratories – is the biggest of its kind in the local admixture market. Customer support has been overwhelming.” www.chryso.com

NOISY OFFICE DESIGNS HAMPER STAFF HEALTH AND PRODUCTIVITY All too often modern designers tend to specify strong materials for offices because of their stylish appearance and durability but, because designers often lack training in acoustics, they don’t understand how “noisy” this kind of design can be, says international acoustics authority Julian Treasure.

Treasure, chairman of the London-based The Sound Agency, says poor acoustics increase noise levels dramatically – and the louder the noise, the greater the negative impacts on staff’s output and health.

“Much of the sound in typical workplaces is undesirable: ringing phones, electromechanical noise, other people’s phone calls, etc. This, to put it bluntly, is noise. Noise is bad for business – so it’s important for designers to have a thorough understanding of how this affects staff and how best to improve offices with optimal acoustic adjustments,” he states.

Flooring can play a major role in such acoustic adjustments, says leading SA flooring supplier, KBAC Flooring. The company – which is celebrating its 50th anniversary in 2019 – believes that important

acoustical elements, such as the correct choice of flooring and furnishings, should be addressed right at the outset: at the design stage.

Neil Duncan, director of KBAC Flooring, explains: “Carpeting absorbs far more airborne sound than other flooring materials can absorb.

Typically, the thicker and higher quality the carpet, the better it will be at absorbing sound – particularly highfrequency sounds.

“The acoustic requirements of an interior vary from project to project and building to building. Improving the intelligibility of speech in a meeting space will require different solutions to those required to create a feeling of privacy in open-plan offices.

The size and shape of a room also play an important role.

“Chairs being moved or footsteps on a floor are examples of impact noise.

A good acoustic environment is always the result of many factors, including choice of ceiling and acoustic panels.

But to effectively control noise from footsteps and other impacts, no flooring alternative is more effective than carpet,” Duncan adds.

He says wool carpets particularly can create

70 LEADINGARCHITECTURE & DESIGN JUNE/JULY 2018

more comfortable working environments. “Wool flooring dampens noise and reduces sound transmissions between floors and rooms. Sound is transmitted by the vibration of air molecules. The fuzzy porous structure of wool carpets and soft furnishings means that sound waves penetrate the pile instead of being noisily reflected into a room. Wool carpets are extremely effective sound absorbers because the individual fibres, tufts and underlay have different resonant frequencies at which they absorb sound,” he comments.

KBAC Flooring distributes imported carpet tiles produced

by Interface modular flooring, a global pioneer in sustainable flooring and environmental preservation. Hannetjie Smith, KBAC sales consultant, says: “Interface has acknowledged that, although increasingly popular, open-plan workspaces

pose formidable acoustic challenges. The company is one of a growing number of carpet producers that has designed flooring that effectively absorbs sound and reduces impact noise at the source.”

Smith says the backing of carpets is an important acoustical factor. “Interface has developed two acoustic carpet tile backing options: SONE and Interlay, which can be used across the entire workspace or limited to smaller, zoned areas with more complex needs. SONE is an integrated backing for more than 40 of Interface’s modular carpet designs. The backing enhances acoustics and softness underfoot and offers sound reduction of up to 33 decibels. Interlay is a resilient, loose-lay underfloor system for 50cm x 50cm tiles that can be used to enhance acoustics and comfort,” she adds. www.kbacflooring.co.za

INNOVATION AND DESIGN EXCELLENCE RECOGNISED AT COROBRIK SAIA ARCHITECTURAL AWARDS

New Residence at 151 Main Road, Constantia: Malan Foster Architects, Cape Town.

This project was painstakingly created over a relatively long time on the site itself. Its structure and materials are experienced as fragile and ‘temporary’, while its relationship to place and its immediate context could be perceived as its only sense of permanence. Thus, this house makes a critically important contribution to local and international architectural traditions and precedent.

The recent Corobrik SA Institute of Architects Awards give recognition to the top architectural projects of recent times.

Five projects received Commendations and a further 24 were presented with Awards of Merit. Six projects received Awards for Excellence, the highest distinction that SAIA can confer on a project in South Africa. They were as follows:

The Delville Wood Memorial: Creative Axis Architects, Johannesburg, and Mayat Hart Architects, Johannesburg.

The Lake House: Koop Design, KwaZulu-Natal

This building commemorates the South Africans who lost their lives in the epic Delville Wood battle of World War I, particularly the members of the South African Native Labour Corps, who had received no official recognition. Although this project’s architects are young, they were able to deliver a commentary on how history, power and memory were previously expressed.

This building is set in the idyllic and undulating hills of the KwaZulu-Natal Midlands, next to a small lake. The plan and section of the building is generous and deceptively simple and direct. The skills of the various craftspeople who worked on the building are clearly visible, as is their pride in their work.

SASOL Place: Paragon Architects, Johannesburg.

Lewis Levin Architects JHGC GIFA SUBMISSION

Johannesburg Holocaust and Genocide Foundation and the City of Johannesburg: Lewis Levin Architects, Johannesburg.

Visitors’ experience of the building is direct and uncomplicated. Unlike so many of the other Holocaust memorials, the architect here does not ‘force’ the message or an emotional response on the viewer. The building, its exhibits and the placing in its physical context does not impose itself on anybody. It is simply there, and it tells its story to those who are inquisitive enough to want to hear it.

In the SASOL Place building, there is a thoughtful and careful expression of form and function in a relatively uncontrolled urban context that portrays deep and sensible knowledge and professionalism.

If anything expresses South African intellectual and corporate ingenuity on the world stage, it might just be this building, the new symbol for SASOL.

According to willowlamp’s founder and creative director, Adam Hoets, the Love Clover range was inspired by a run he’d gone on in the mountains with his then fiancée – now his wife. They happened upon fields of clovers. “Since that day, she encouraged me to

use the shape of the four-leaf clover in my work.”

Initially, only one lighting design bearing this distinctive motif was planned, but then Hoets decided to expand the range to three pendants and one chandelier. The challenge came about when he tried to capture the sense of joy that is associated with clovers, while still creating sophisticated designs.

“As cute and cheerful as four-leaf clovers are, it took me a long time to translate them into three-dimensional objects that were interesting,” Hoets says. “Eventually, through trial and error, the solution presented itself in what is now a four-piece range making use

of heart-shaped, sensual and voluptuous forms.”

Despite the resultant sophistication, Hoets felt each light had to have a playful name to properly represent what first inspired it into being – hence fittings that bear titles such as Secret Love, Big Love, Baby Love and Lucky Love.

The Secret Love pendant is powered by four LED lights and comprises four tapering segments, each cut to reveal heart patterns from any angle.

Big Love is a striking chandelier with four tapering segments that are lit by five halogen or LED lamps in Pyrex balls, while Baby Love is almost a smaller sibling, but in pendant

form. It resembles Big Love but with a more delicate glow, and uses only a single LED lamp.

Completing the collection, Lucky Love plays the most on the romantic element of the range, and has more of a floral look than a botanical one. Its four heart-shaped segments bow from a single halogen or LED light to resemble an elongated four-leaf clover cutaway, making this pendant best seen from below.

All Love Clover lights are available in a selection of coloured finishes, including brass, copper, silver, smoke, rust, white, red, black and mixed metallic. www.willowlamp.com
