Shelter Afrique roots for green buildings

Toyota Tsusho inks agreement to build a 25MW solar Power Plant in Benin

Toyota Tsusho Corporation has signed an agreement with the Beninese Electricity Production Company to build a 25MW solar power plant in Benin. This project is the first major renewable energy power plant development effort by a Japanese corporation in West Africa.

Toyota Tsusho has contributed to increasing the production of renewable energy in Africa, including the completion in 2015 of a wind power project in Egypt with a capacity of 262 MW and the start of commercial operation of a geothermal power plant in Kenya with a capacity of 280 MW.

Pan African housing development financier, Shelter Afrique, has implored stakeholders in the built environment to put more emphasis on addressing climate change, describing it as "one of the most pressing challenges of our era."

Speaking at the Zambia EDGE Discovery Workshop - organized by Shelter Afrique Centre of Excellence (CoE), in partnership with IFC EDGE and the Ministry of Infrastructure, Housing, and Urban Development, Zambia - Shelter Afrique Managing Director, Thierno Habib Hann, said the company shares the goal of fostering sustainable and responsible housing practices for a more resilient future.

"In a world where climate change is reshaping landscapes and altering lives, our collective efforts hold the power to forge a more sustainable path forward," Mr. Hann said.

Through its Centre of Excellence, Shelter Afrique collaborates with IFC to deliver EDGE Discovery Workshops to developers and other stakeholders in the housing industry across Africa, to accelerate the development of resource-efficient affordable housing.

Construction work is scheduled to be completed in 2024. Toyota Tsusho conducted a project development study with support by the Benin government such as the Beninese Electricity Production Company, under the programmeof the “Feasibility Study Project of Overseas Development for High-Quality Energy Infrastructure” by the Ministry of Economy, Trade and Industry in FY2021.

The construction of the 25MW solar power plant in Benin will be marketed as a Japanese public-private cooperation project. That will provide reliable electricity at a lower cost. Through the development and application of new renewable energy sources, Toyota Tsusho will support the realization of a decarbonized society. As well as green economic growth in Africa in order to leave a better global environment to the next generation

HEAVY EQUIPMENTJCB ‘Zero Carbon’ Hydrogen Engine Debuts at US Expo

The JCB hydrogen engine, which already powers a prototype backhoe loader and telescopic handler, is the company’s zero-carbon emissions solution for construction equipment.

JCB hydrogen engine production

JCB Chairman Lord Bamford said engineers at JCB Power Systems – the company’s engine factory in Derbyshire, UK – have made huge strides in a short space of time to build a groundbreaking hydrogen internal combustion engine.

“As the first construction equipment company to develop a fully working combustion engine fuelled by hydrogen, I’m delighted we are now able to present this technology on the international stage,” Mr Bamford said in a statement.

The new JCB hydrogen engine is designed to utilise a brand-new combustion technology that replaces diesel fuel with hydrogen gas.

Using and adapting established engine technology with readily available components, hydrogen is ignited and power is delivered the same way as a diesel engine.

“We kept the DNA of the engine; the only difference is the fuel, which is clean-burning hydrogen gas,” says Ryan Ballard a senior director at JCB.

As such, machines fitted with a hydrogen engine can do everything their diesel-powered equivalents can do.

JCB is not new to these kinds of

inventions.

The company designed the world’s first battery-electric mini excavator and has been fronting electric technology development to meet customers’ demands for zero-carbon equipment with its E-TECH range.

It currently holds the largest electric lineup in the construction industry.

Exploring the Pros and Cons of Hired-In Plant Equipment

The choice between hiring or buying plant machinery in construction can significantly impact the success and profitability of the project. Plant machinery plays a vital role in ensuring efficient and timely project completion, however, making the right decision requires careful consideration of various factors. We will explore the advantages of hiring plant equipment, from the cost of hiring vs investing in plant equipment to the capacity and flexibility of hired-in plant equipment, we will also dive into the potential disadvantages; including reliance on external suppliers and factors to consider including project duration; to provide a balanced argument so that you can make a more informed decision on your next project.

Advantages of Hired-In-Plant Equipment for Long-Term Construction Projects

In construction projects, opting to hire plant equipment brings a range of advantages when compared to investing in your own equipment, hired-in plant equipment provides a cost-effective solution, especially for shorter-term construction projects, allowing companies to

allocate their financial resources more efficiently. Rather than making a substantial upfront investment to purchase the required machinery, companies can pay rental fees over the project's duration, improving cash flow, and enabling better budget management.

Secondly, hiring plant equipment provides access to a wide range of equipment options. Construction projects often demand specialised machinery from bulldozers and excavators to machinery for smaller tasks. Furthermore hiring plant equipment offers the flexibility to upgrade or switch machinery as project needs evolve. By opting to hire, constructors gain the advantage of choosing from a diverse selection of equipment tailored to their specific project needs, and If the project needs shift or new equipment becomes necessary, contractors can easily upgrade or switch to different machinery without the financial burden of selling or disposing of owned equipment. Equipment rental companies typically offer an extensive inventory, encompassing excavators, bulldozers, cranes, concrete pumps, and more. This variety empowers con-

tractors to select the right equipment for each project stage, ensuring optimal productivity and efficiency.

Additionally, hiring plant equipment reduces maintenance and repair responsibilities. Rental companies typically handle routine maintenance, servicing, and repairs of rented machinery, therefore relieving contractors of the lengthy and potentially costly tasks of upkeep and maintaining the machinery, hence saving valuable time, effort, and costs associated with maintenance and repairs. By outsourcing these tasks to the rental company, contractors can focus more on project execution while entrusting equipment maintenance to the experts.

Disadvantages of Hired-In-Plant Equipment

As touched on above there are notable advantages to hiring in plant equipment for construction projects around cost, accessibility, and maintenance. However, it is also essential to consider the potential disadvantages of hiredin-plant before making a decision.

6 CR | July/August 2023 www.constructionreviewonline.com COVER STORY

One primary drawback work noting is the potential for higher costs in the future, as we touched on earlier, whilst hired-in-plant brings with the advantage of a short-term cash flow position a huge advantage for short-term projects, the rental fees over a longer period of time can potentially surpass the upfront cost of purchasing the machinery. Hence, it is vital to carefully consider the project duration and compare rental costs against the cost of purchasing outright.

Another disadvantage is the limited availability of rental equipment during peak construction periods. When multiple projects are in progress simultaneously, the demand for specific machinery can exceed supply. This situation can delay securing the desired equipment within the desired timeframe. Proper planning and early booking become crucial to ensure access to the required machinery and avoid project disruptions.

Dependency on external suppliers for equipment availability is also a consideration. Contractors relying on rental equipment must rely on the rental company's ability to maintain a sufficient inventory and provide timely service.

Delays or unavailability of rental equipment can disrupt project timelines and hinder progress. Establishing strong communication channels and maintaining a good relationship with the rental company can help mitigate these risks, but some level of dependency remains.

Factors to consider when deciding to Hire Plant Equipment

As we have touched on a few times throughout this blog the decision to hire plant equipment vs investing in plant equipment comes down to a range of individual factors, with the biggest of these being the project duration, for instance, for long-term construction projects (one that may go on for years) it may be a wise decision to invest in your own equipment, this way direct access to the equipment without going through an external rental company may significantly speed things up, as well as potentially saving significant financial capital.

Another factor to consider relates to the type of equipment needed, as touched on at the beginning of this blog, each piece of equipment has its own unique tasks and responsibilities it

can complete, from cranes for heavy lifting to excavators for digging. Plant machinery such as cranes and bulldozers may be wise to hire in from a specialised company focussing on this type of machinery, with likely a substantial initial cost, its likely more cost-effective to hire in. On the other hand excavators and smaller scale machinery that has a smaller upfront cost and may be used for longer over the project duration is likely something that can be invested in.

However, ultimatly the decision comes down to a businesses position and preferences, a smaller company is likely not going to have the financial capital to invest in a wide range of machinery, so hiring is likely the best option, whereas a much larger organisation will likely have more freedom and capital to make a decision based on the factors mentioned above. However, whichever choice is made it is vital to ensure your business's plant machinery; whether owned or hired-in; is well protected with plant insurance, providing peace of mind over finances but also protecting project effectiveness and reducing downtime.

What are fasteners in construction

Fasteners are used in the construction industry to join two or more objects together in a non-permanent way. Each construction project requires a different kind of fastener in order to ensure a safe and strong final construction. Fasteners are very important in construction because each component or machinery or vehicle needs these fasteners to hold it together.

The fasteners are the main components that are used in many sectors like automation, manufacturing, infrastructure and others in which different types of items are produced that require assembling of machinery or parts of different vehicles.

Importance of a screw/fasteners

Screws are widely used in threaded fasteners to hold the objects together, mainly in devices such as screw tops for containers, vices, screw jacks and screw presses.

A fastener can be a special type of nail that has spirals on its sides. The fasteners are used to make substances rigid and long-lasting and make it look clean as well.

Different types of fasteners are used in the industry for different purposes. An automobiles requirement for fasteners will be different from the requirement of that of a fastener that is used in an aeroplane. The fasteners hold the industry

together.

Types of fasteners

There are different types of fasteners that are available in the market based on the requirements. Mechanical fasteners come in many forms like screws, nails, nuts, bolts, washers anchors as well as rivets. The types of fasteners can be explained in detail below:

1. Screws

Screw fasteners are one of the most versatile types of fasteners. The threaded shafts present give them a more durable holding power. These fasteners do not require anything to hold them in place. Screws come in a wide variety of types and can be named as follows:

Wood screws – These have a coarse thread and a tapered head.

Deck screws – These include self-tapping design and are corrosion resistant.

Machine screws – These have uniform thickness and do not taper off from the bottom.

2. Nails

A nail has greater sheer strength and is a better choice for various applications.

Common Nails – These have a thicker shank for greater holding power for many different applications.

10 CR | July/August 2023 www.constructionreviewonline.com FASTENERS

Box Nails – These offer easier driving with steel construction and a diamond point-tip. Brad Nails – These can easily blend into wood trim.

3. Bolts, Nuts & Washers

Nuts and bolts are other common types of fasteners. These two pieces work together and hold the components together. You can insert the bolt into the two parts you want to join and then fasten it in place with the nuts.

4. Anchors

These types of fasteners are used to connect something to a material like drywall or concrete.

Which fasteners are commonly used?

The most common types of fasteners that are used are screw, nuts and bolts. It also involves washers. Other more specialized types of fasteners that are used are captive threaded fasteners, studs, threaded inserts and threaded rods.

4. Coating

Coatings are used to add or increase the corrosion resistance. Zinc, hot-dip galvanizing and chrome are the most common types of coating used.

Conclusion

You can purchase different types of fasteners from Screwexpert based on your requirement of length, size, and coating types. You can also go through the website for more details.

Points to Remember While Choosing Fasteners

Consider the fasteners primary use before purchasing and buy it according to the requirement.

Know the specifications of your requirement

Consider the material and its corrosion-resistant power.

Consider the price.

1. Material

Get to know the requirement before choosing the fastener. Fasteners come in different material and it is always the best option to buy the one made up of stainless steel so that it remains corrosion resistant.

2. Head Shapes

It is also important to know the type of head that is needed. For example flat head, truss head, pan head. Each type has its own distinct purpose.

3. Length

Length is also an important factor that determines where you can source your fastener from. The sizes vary due to variations in requirement.

Importance of Compressors in Construction

The construction industry relies on air compressors for a wide range of tasks and processes. From grinders to jackhammers, many tools and pieces of equipment need a strong, high-volume stream of pressurized air to get the job done. Many building processes require a reliable air compressor for peak efficiency.

A contractor’s air compressor is a very useful and essential machine for building projects. Compressed air can power a vast range of tools because of its high output and efficiency. Construction sites rely on air compressors and air-powered tools for many applications, from digging trenches to hoisting materials.

Benefits of a compressor and air-powered tools:

Maintenance: Air compressors are pretty easy to maintain — you’ll need to regularly change the compressor oil and air filters and schedule maintenance every few months. Keeping your air-powered tools in working shape is relatively simple because they have fewer moving parts than electrically-powered options.

Versatility: An air compressor can power a range of tools and requires only a single generator to operate, making these compressors advan-

tageous for remote worksites.

Safety: Fires and electrocution are less likely to occur on the job site when working with compressors and air-powered tools than with other types of tools.

Choosing an Air Compressor for Construction

If you are interested in investing in an air compressor for construction applications, be sure to consider the following factors to make the right choice for your business:

Size: When choosing a compressor, it is vital to find options that have enough power for your equipment. Consider how much you need and choose a size that suits your requirements.

Portability: If you’re working on construction job sites, you will need an air compressor that you can transport from job to job. Look for one you can move with the equipment you already have.

Noise: Air compressors can generate varying levels of noise. Consider the environments you often work in and if choosing an especially quiet model would be beneficial.

Tools: Take inventory of the air tools you al-

ready have. Finding a generator that is compatible with your existing equipment can be very valuable and save you a lot of money. For example, your air-powered equipment will have specific cubic feet per minute requirements. Ensure you choose a compressor that’s suitable for your applications and provides enough power.

Types of Air Compressors Used in the Construction Industry

The construction industry utilizes a few different kinds of positive displacement air compressors to complete building projects. Consider the advantages of the following types:

Rotary screw: This kind of compressor utilizes two screws rotating opposite one another to compress air within a sealed chamber. Rotary screw compressors are highly durable and ideal for heavy-duty use on construction sites.

Reciprocating: Also called a piston compressor, these models use a piston to compress air and displace it within the chamber. This type is especially powerful and slightly smaller than rotary screw options, making them ideal for applications that need portable equipment.

12 CR | July/August 2023 www.constructionreviewonline.com COMPRESSORS

The Importance of Having Portable Air Compressors for Construction Applications

Portable compressors make it easy for you to get your equipment where it needs to go, whether you are traveling between multiple jobs or need to move the equipment around on a single site. It is important to have tools that offer flexibility when you need to access those remote and hard-toget-to areas.

Towable compressors are perfect for construction applications. They require transportation equipment to tow them and are typically compact enough to travel to job sites with rougher terrain and remote work areas.

Common Construction Air Compressor Applications

Consider the following applications for air compressors on construction and building job sites:

Pneumatic Tools

Air-powered construction tools, also called pneumatic tools, allow for a diverse range of applications, including:

Jackhammers: Pneumatic jackhammers act as a hybrid of a hammer and chisel. They utilize compressed air to drive the tool up and down to break up surfaces. They are a key tool for demolishing old concrete and pavement before starting new concrete construction.

Drills: Air-powered drills work similarly to jackhammers. Construc-

tion crews use them for digging deep into the ground, often before the pile-driving equipment finishes the job.

Impact wrenches: While it can be tedious to loosen and tighten bolts manually, an impact wrench can expedite the entire process thanks to the help of compressed air.

Nail guns: Pneumatic nail guns are another handy tool that saves construction teams valuable time. The power they produce can help streamline projects like installing roofing and siding.

Grinders: The construction industry utilizes different types of air-powered grinders for various tasks, from cutting to polishing. The compressed air enables high-speed rotation for dealing with abrasive materials.

Sanders: Air-powered sanders are available in many different types, each of which uses compressed air to power the motor and propel the sanding pad.

Pneumatic equipment is generally lighter and less expensive than electrically-powered tools. Their reliability is a key reason why the construction industry favors air-powered tools. Another advantage of having air-powered tools for your construction project is the ease with which you can switch between instruments. An air compressor can power each of them without needing multiple power sources.

Whether you need to break up rocks or smooth surfaces, powering your pneumatic tools with an air compressor will benefit your construction business.

Air-Powered Lifting Equipment

The construction industry also uses air compressors to power pneumatic hoisting and material handling equipment, such as air-powered hoist lifts.

These air-powered machines help complete a variety of job site tasks involving lifting and lowering materials. They are ideal for remote job sites without easy access to power, as the equipment uses pressurized air to generate enough force to hoist products.

Choosing the right pump for construction

Water pumps are commonly used on construction sites to remove excess water accumulated due to heavy rain or high water table. They primarily serve two purposes: keep water out of foundations, tunnels, and other excavations pits; and provide a supply of water for jetting and sluicing, pumping water for cofferdams, etc.

The choice of water pumps for construction sites is dependent on the complexity of the project, the amount and rate at which the liquid is removed, the type of liquid, the loss due to friction, the height of suction lift, and the size of the pump.

This article explores the important types of pumps used for construction sites and the factors to consider while choosing the right water pump.

A centrifugal pump consists of a rotating impeller that moves water into the pump and discharges it. The rotating impeller creates a vortex as a result of which air is taken from the external environment and the developing atmospheric pressure causes the water to rise through the pump.

All the liquids can be pumped using a centrifugal pump irrespective of their viscosity. These pumps work efficiently even with thin liquids. In certain situations, the casing of a centrifugal pump is filled with vapors or gases that inhibit pumping. Such situations demand the priming process. Priming is the process of filling the casing of the pump with liquid before starting the pump. There are self-priming centrifugal pumps that have water in reserve within the impeller chamber.

Centrifugal pumps can be electric, hydraulic, gas-powered or manual type. These are often used in tunnel and foundation construction pits to handle oil, sludge and sewage.

Properties of Centrifugal Pumps

1.Centrifugal pumps are employed to pump water in facilities where pneumatic systems are compatible, and there is no requirement for suction lift.

2.It is used to pump water from domestic wells. 3.Centrifugal pumps convey continuous pressure source for the fire protection system. It can help enhance the pressure in water intake lines.

4. These can act as a sump pump in either vertical or horizontal configurations.

5. Centrifugal pumps require recirculating liquid to prevent the issues due to overheating. This is mainly caused due to low flows.

6. Proper operation of centrifugal pump requires priming.

Displacement Pumps

Displacement pumps can be classified into:

1. Reciprocating pumps

2. Diaphragm pumps

2.1. Reciprocating Pumps

Reciprocating pumps work based on the movement of the piston in a cylinder. Large reciprocating pumps possess 2-3 cylinders. When the piston moves in one direction, the water is drawn into the cylinder. When the piston moves to the rear end, the water is pushed out. Reciprocating pumps gain high efficiency and are reliable. They can pump the liquid at varying heads with uniform discharge. These are best suitable for low-flow conditions.

2.2. Diaphragm Pumps

Diaphragm pumps work by drawing water into the cylinder during the raising and lowering of

14 CR | July/August 2023 www.constructionreviewonline.com PUMPS

a diaphragm. When the diaphragm moves out, water is sucked into the cylinder. As it moves down, it is discharged to the delivery pipe. Diaphragm pumps can deliver liquids that contains 10 to 15% solids and can work with water with varying flow characteristics.

Submersible Pumps

Submersible pumps or sump pumps or electric submersible pumps (ESP) lowers the groundwater and remove water from a deep sump. The pump unit consists of a sealed motor close-coupled to the pump body. The whole unit is submerged in the fluid to be pumped.

The sump pump consists of a centrifugal unit and a motor mounted in a single cylindrical unit as shown in Figure-3. There is a space between the pump and casing that facilitates the movement of water up to the rising main.

Submersible pumps are used for heavy-duty pumping in construction which mainly involves lifting of gritty water.

Airlift Pumps

Airlift pump, as shown in Figure-4, consists of a vertical pipe that is submerged in a well in such a way that a major portion of the pipe lies below the water level. Compressed air is blown to the lower point through an air inlet. The air at the bottom carries the water up the pipe and finally to the delivery area. Airlift pumps are mainly used for moving silt from the base of a cofferdam.

How to Decide Where to Locate Electrical Generators

Many property owners are challenged with the question of where to locate their electrical generators. The difficulties are understandable: Generators —whether they’re emergency systems, legally required standby systems, or optional standby systems — are needy beasts that require a fuel supply, a combustion air supply and exhaust pathway, and a cooling air supply and exhaust pathway. They are connected via conductors and conduits to electrical power systems via automatic transfer switches or switchgear. They have extensive controls connectivity and alarms. They are generally noisy, and they generate problematic combustion emissions.

These characteristics complicate decisions about location. Property owners do not want generator operation to be so loud as to disrupt the function of the building, nor do they want the combustion exhaust gases to enter the building via outside air intakes. It’s also possible that the exhaust from the generator’s warmer cooling air reduces the rated performance of other generators or any HVAC equipment – another scenario to avoid.

To further complicate matters, the cost per kilowatthour (kwh) of power from a generator is usually higher than that supplied from the electrical utility, so most owners want to reduce generator run time. Quite often, the air permits for the generator installation will limit their run time when utility power is available.

A key step in addressing these issues is a fundamental decision: to locate the generator in an ownerconstructed building or outside the building in vendorsupplied housing. Each option offers advantages and disadvantages:

Generators Inside a Building

Plusses

It is more comfortable to perform maintenance (and may lead to better maintenance) and repairs inside a building than in a cramped enclosure.

The generator’s condition and status can easily be observed visually.

16 CR | July/August 2023 www.constructionreviewonline.com GENERATORS

Minuses

The installation will be more expensive. Furthermore, the one-ofa-kind layout could lead to design or construction errors. Generator enclosures are a standard and vetted design that have been used extensively in manufacturing.

Providing adequate cooling air flow into the building and around the generators is more challenging.

Day tanks inside a building are limited to no more than 660 gallons (total), resulting in bulk fuel storage being required. If the owner is a data center operator seeking Uptime Institute Tier III or IV certification, the fuel system will have to be concurrently maintainable (maintained while the site is powered by generators) and fault-tolerant. This generally leads to concurrently maintainable double valving and redundant tanks.

A fuel polishing system may also be necessary with bulk storage of fuel.

Dispersing the generator exhaust fumes is more expensive and challenging when in a building since the fumes are usually routed horizontally out of the building instead of out or up. Consequently, the fumes can be more easily drawn into a building’s outside air intakes.

Required clearances around the generators will require additional square footage.

A generator failure incident, such as a thrown rod or a fire, is more likely to impact an adjacent generator.

Generators in Enclosures with Sub-Base Fuel Tanks

Plusses

Installation will be less expensive since this is the most common way generators are purchased by data center hyperscale and colocation customers. The trend has increased generator industry competition and innovation.

Quite often, no fuel bulk storage is required since the fuel required per generator can be stored underneath each generator. With no bulk storage, Uptime Institute Tier III and Tier IV certification is greatly simplified.

Required clearances around the generator can be achieved by opening enclosure doors/panels without requiring an extension of the building footprint.

Fuel polishing is usually done by the fuel supply vendor during regular re-fill visits.

Generators in enclosures can be stacked if there is limited site area available.

Dispersing the generator exhaust fumes is easier since the fumes can be directed into the cooling exhaust air stream or straight up.

Minuses

During a hot summer or cold winter, a cramped enclosure is less comfortable for performing maintenance (and may lead to poor maintenance) and repairs than inside a building.

It can be difficult to get 120,000 CFM air supply into a generator enclosure with a sand louver (in the desert), and a snow prevention scheme (cold climates) and may necessitate a remote radiator.

The answer to where an owner should locate electrical generators on a building site will vary for each unique situation. However, as the comparative length of the plusses and minuses categories above suggest, the design and construction risks are reduced by utilizing exterior generators in enclosures with sub-base fuel tanks. Computational fluid dynamics (CFD) studies on exteriors can mitigate the risk of entraining combustion air into the building intakes or reducing adjacent generator capacity or HVAC cooling capacity.

The Different Types Of Solar Panels You Should Consider For Your Home

If you’ve considered adding solar panels to your home, you’ve probably also considered the amount of money and energy you could save by doing so. The potential savings is important, of course, but it isn’t the only thing to keep in mind when it comes to making the switch—you also need to decide what type of solar panels are right for you.

Because there are several types to choose from, it isn’t as easy as simply scheduling an installation appointment.

Explore Options

The first thing to do when figuring out which type of solar panel is right for your home is to acquaint yourself with the choices at hand as well as how many solar panels you want.

There are three main types of solar panels available for residential use. They are: monocrystalline, polycrystalline and thin-film.

A fourth option, solar roofing shingles, is a newer and more expensive technology—but certainly a suitable (and enticing) choice for those with the budget to cover the initial costs.

Monocrystalline Solar Panels

When you picture rooftop solar panels, you probably picture monocrystalline simply because they are very commonly used. And while all solar panels offer some

level of energy efficiency, monocrystalline is considered the most efficient of the bunch. How efficient? Up to 20%, Energy Sage reports, meaning that 20% of the sunshine that hits a monocrystalline panel is converted into usable energy. Monocrystalline panels are also:

Made of an individual pure silicon crystal (in other words, the silicon comes from one source)

Cylinder-shaped

Uniform in color

Durable and long-lasting (some come with warranties up to 30 years)

Able to generate between 300 and 400 (sometimes even more) watts of power each

The downside? Monocrystalline often requires a larger upfront investment than some other types of solar panels. This is because they are more expensive to make—a cost that, naturally, gets passed on to the consumer.

And if 20% isn’t quite efficient enough for you? No worries—under the monocrystalline umbrella falls an additional type of solar panel called the PERC (passivated emitter and rear cell). While use of this technology is still ramping up, experts say it offers even more efficiency than traditional monocrystalline panels (thanks to an added layer of silicon material on the panel’s back side) and isn’t particularly cost prohibitive to manufacture.

Polycrystalline Solar Panels

18 CR | July/August 2023 www.constructionreviewonline.com SOLAR PANELS

Polycrystalline panels, on the other hand, are less expensive to make and therefore less expensive for the customer. The cost difference is attributed to the manufacturing process—rather than the individual silicon crystals used to make monocrystalline, polycrystalline panels are made from many different pieces of silicon that are separated into fragments and melted together.

Polycrystalline is also somewhat less efficient than monocrystalline, producing around 250 watts of power each rather than 300-plus. Physically, though, they look similar to their monocrystalline counterparts and last almost as long (warranties are in the 25-year range, but vary by brand).

Thin-Film Solar Panels

Thin-film solar panels have a few advantages over monocrystalline and polycrystalline ones. First of all, they are comparatively lightweight. They are also malleable (the others are rigid), making them easier to install than the thicker, heavier varieties.

They are also far more affordable to manufacture than other types of solar panels and also more affordable to install.

Amorphous Silicon (a-Si) Thin-Film

Amorphous solar panels are silicon-based, like the others, but in this case, the silicone portion is just the first of three very thin layers (the second layer is heat-conductive; the top layer is protective).

Amorphous panels also do well in warmer climates because they can withstand intense heat and are more adept at generating energy on darker days (meaning the sun doesn’t have to be shining bright in a clear blue sky for them to do their job).

Unfortunately, amorphous panels don’t last as long as other types of

www.constructionreviewonline.com SOLAR PANELS +254 724 256 665 +254 733 714 108 / +254 734 800 201

solar panels, you’ll only get between 10 and 20 years out of them. Furthermore, they are only around 7% efficient.

Cadmium Telluride (CdTe) Thin-Film

Cadmium telluride thin-film is the second most used solar cell type in the world after crystalline cells. However, CdTes aren’t the best in terms of efficiency,

Copper Gallium Indium Diselenide (CIGS) Thin-Film

Also produced with cadmium, Copper gallium indium diselenide (CIGS) thin-film is above-average in efficiency but is very expensive. The cells place Copper, Indium, Gallium, and Selenide layers on top of each other to efficiently convert sunlight into energy.

(PERC) Passivated Emitter and Read Cell Panels

PERC (passivated emitter and rear cell) panels are a newer type of solar technology designed to be more efficient than traditional monocrystalline panels. While this technology is still ramping up, PERC panels feature silicon material on the panel’s backside to achieve higher energy conversion efficiency. They also aren’t particularly cost-prohibitive to manufacture.

Solar

Panel Types by Efficiency

Monocrystalline solar panels are the front runner as the most efficient panels with 20% and up. Polycrystalline solar panels are a close competitor with 15% – 17% efficiency. While CIGS thin-film has 13% – 15% efficiency, CdTe thinfilm has 9% – 11% efficiency, and a-Si thin-film has 6% – 8% efficiency.

Solar Panel Types by Cost

Although monocrystalline solar panels are the most efficient, they are also the most expensive type of solar panels, with the average cost being $1 to $1.50 per watt. Polycrystalline solar panels are next in line as the most expensive, costing $0.70 to $1 per watt. While CIGS thin-film costs $0.60 to $0.70 per watt, CdTe thin-film costs $0.50 to $0.60 per watt, and a-Si thin-film is the least expensive at $0.43 to $0.50 per watt.

Solar Panel Type by Power Output

Most residential solar panels on today’s market are rated to produce between 250 and 400 watts per hour. Monocrystalline solar panels can generate between 320 watts and 375 watts of power capacity, while polycrystalline solar panels gen-

erate ratings between 240 watts and 300 watts. Thin-film panels don’t come in uniform sizes, so there is no standard measure of power capacity. However, thin-film solar panels have a lower power output comparatively.

Solar Panel Type by Appearance

One benefit of thin-film solar panels is their sleek appearance. Labeled the most attractive of the three solar panel types, the panel’s all-black thin design allows them to lie flat against roofs, so they blend in seamlessly.

Other Factors to Consider When Comparing Panel Types

In addition to efficiency, cost, power output and cost, there are several other factors to consider when determining which panel type is right for you. For instance, the weather in your area should undoubtedly be a consideration.

Hail Rating

Although most solar panels are protected by a thick layer of tempered glass that can tolerate severe impacts, a hail storm can present significant problems for your solar panels. Therefore, they are tested for hail impacts.

On average, solar panels are certified to withstand hail of up to 1 inch falling at approximately 50 mph. Monocrystalline and polycrystalline solar panels are ideal for areas that experience heavy hail. At the same time, thin-film solar panels are not ideal for hail since they have a thin design.

Temperature

The temperature outside can determine how efficiently solar panels generate energy. Solar panels work best at about 77°F. If the peak temperature of your solar panels gets higher than 149°F, solar panel efficiency can decline.

Fire Rating

In the event of a fire, solar panels are required to match the fire rating of the roof where they are installed to ensure they do not accelerate the spread of flames. Therefore, solar panels now carry the same fire classification rating as roofs, such as:

Class A: severe fire test exposure

Class B: moderate fire test exposure

Class C: light fire test exposure How Do Solar Panels Work?

Before deciphering which solar panel type is right for your home, you should know how solar panels work and what to expect when you utilize them. The first thing to know is that solar panels harness the sun’s power and are an endless energy source that can perform all necessary functions. Solar panels are also able to create this energy in a manner that can save not only the planet but also your money.

Solar Roofing Shingles

Efficiency and price aside, some homeowners are hesitant to go solar for purely aesthetic reasons. In other words, they just don’t like the look of solar panels. If this is you, consider solar shingles.

Solar shingles allow you to get many of the benefits of solar panels without disrupting the look and feel of your roof. They are manufactured using the same technology as solar panels, and they are available at a variety of price points (depending on the brand).

Sadly, the cons are not insignificant. First and foremost, price is a huge concern—shingles are almost always more costly (especially if you go with a brand like Tesla, which launched a line of solar roofing shingles in 2019). Not only that, solar shingles are in short supply. So, even if you have the budget and the desire to add them to your roof, you might not be able to track them down.

Efficiency-wise, solar shingles are also only between 14% and 18% efficient, which isn’t bad compared to the less efficient amorphous panels but, on the lower end, doesn’t really seem all that great next to the monocrystalline ones.

Furthermore, solar shingles won’t necessarily work on every type of roof. Most are made to replace asphalt roofing tiles only (with some exceptions). The most cost-effective route? Coordinating overall roof replacement with the addition of solar shingles, which has a higher upfront cost, but is more likely to even out in the long run.

Which Type of Solar Panel Is Best?

Due to a wide selection of capabilities, quality, price points and features, shopping for the perfect solar panels for your home can be overwhelming. However, with some help, you can typically find the panel type that suits your home’s needs.

Laxmanbhai Construction Limited

70 Years of Shaping the Built Environment

According to the National Construction Authority (NCA), Kenya has over 70,000 building contractors. With such a huge number, it is no surprise that the industry is characterized by intense competition for the limited jobs available.

In order to sustain their business over the long term, contractors must demonstrate exceptional professionalism, deliver high-quality work, inspire trust, and possess sufficient capacity. Consequently, only a select few companies in the country meet these criteria and manage to thrive in the industry.

Laxmanbhai Construction Limited is indisputably among the few companies that have shrugged off industry challenges to become one of the most consequential players in the building and construction industry in Kenya.

For seven decades, the company has traversed the industry like a colossus leaving its signature on some of the most iconic buildings in Kenya.

In fact, Managing Director Mr Manji Kanji Raghwani does not blink when he asserts the company has no equal. “Our legacy is unrivaled,” he says. He adds that over the years, the company has managed to remain a force to reckon with due to adherence to the core principles of its founders, namely professionalism, honesty and integrity. Anchoring on the three, coupled with commitment to complete projects without cost or time overruns and to the satisfaction of clients and consultants, has seen Laxmanbhai become the first-choice contractor in many projects, including those with project value running into billions of shillings.

Established in 1953 by Laxmanbhai Bhimji K. Raghwani, Laxmanbhai Construction Limited is among the few construction companies founded before Kenya attained independence that not only managed to survive the transition to self-rule but also achieved monumental growth. Notably, the company is synonymous with Kenya’s developmental journey, having been involved in key projects in every defining historical moment of the country.

The Board of Directors. From left: Mr Virji K. Raghwani, Mr Arvind M. Raghwani, Mr Manji K. Raghwani (Managing), Mr Khusal R. Raghvani and Mr. Ramji K. Raghwani.

Commitment to Excellence

“Wherever we work, our clients and consultants value our trademark commitment to excellence, quality, innovation, sustainability and safety,” explains Mr Manji Raghwani. He adds that the company has built a reputation of deploying its full range of expertise and collaborating with both clients and consultants to deliver successful projects that consistently set new benchmarks in the construction industry.

That Laxmanbhai takes pride in delivering unparalleled, high-quality workmanship and services, and is determined to consistently exceed the expectations of the industry is evident. Unlike many contractors, the company has invested heavily in personnel, equipment and machinery. The contractor believes that in order to be able to serve clients effectively and finish projects on time, investment in new and modern equipment is inevitable.

State-of-the-art Equipment

“To deliver quality projects you must be in a position to mobilize the appropriate equipment. This is why we have an arsenal of equipment for every kind of project,” states Mr Manji. He adds that the company’s portfolio of equipment includes specialized concrete pumps, concrete batching plants, earth movers, trucks, excavators, tower cranes, mobile cranes and slip-form equipment, welding machines, hydraulic breakers, air compressors and generators that allow the company to offer tailored and continuous on-site service across the country.

While assembling the necessary equipment is critical, having the right personnel is paramount. According to Mr Manji, the success of Laxmanbhai is to a high degree a result of dedicated staff from the top management to the lowest cadre. The commitment of the company to treat employees as valued assets has paid off handsomely particularly when it comes to project delivery. “In this industry you need a team that is committed and motivated,” he asserts, adding that employees play a major role in ensuring projects are delivered on time and on budget. They are even more important in massive projects where coordination and seamless working is critically needed to guarantee that projects meet the expectations of clients.

It is for this reason that Laxmanbhai has become a powerhouse construction company in Kenya where for decades it has served clients with an honest, reliable performance and a customer-first attitude. This is evident from the overflowing basket of iconic, breathtaking and trailblazing projects the company has undertaken. The projects, which cut across commercial and office

buildings, hotels, schools/common buildings, public buildings, residential and apartments to interior fit-outs and partition works, are a testament of Laxmanbhai’s ability to deliver on its promises.

All Clients Treated Equally

For the company, which has implemented projects with a price tag as high as KSh4.9 billion and as low as KSh2 million, theirs is no distinction in terms of project delivery. “All clients are valuable to us and we aim to deliver to the expectations of each client,” avers Mr Manji. He adds that the tenets of treating all clients in the same way have been passed down from the company’s founders and will continue to define Laxmanbhai for years to come. In fact, this principle has been instrumental in guaranteeing repeat clients for Laxmanbhai. “We have managed to grow immensely because of repeat clients,” explains Mr Manji, adding that in the building and construction industry, word of mouth and referrals is more important than just tendering for projects.

It is not hard to see why word of mouth and referrals play a central role in the industry. Though flooded with construction companies, all projects originate from consultants. In Kenya, a handful of consultancy firms dominate major projects. For these firms, working with a seasoned and trustworthy contractor is often the bottomline, with Laxmanbhai being the first choice for many of them owing to the company’s rich history. “We have a very cordial working relationship with consultants and most will not hesitate to choose or recommend us for any project,” says Mr Manji. He adds that while disputes are bound to arise in some projects, having a win-win mechanism of resolving them has been crucial in safeguarding long-term working relationships. This explains why Laxmanbhai has continuously worked with a lean set of consultants in its portfolio of projects.

Iconic Projects

The dominance of Laxmanbhai in Kenya’s building and construction industry is well illustrated by the projects the company has implemented over the years. The company’s name is inscribed on many skyscrapers like Britam Towers, Teleposta Tower, Rahimtulla Trust Tower, Lonrho House, Nyayo House among many others. It also has its name in many five-star hotels like The Stanley, English Point Marina, Villa Rosa Kempinski, Hemingways Hotel Karen, Crowne Plaza Hotel Annexe among others.

Laxmanbhai is also the contractor behind many iconic buildings such as I&M Headquarters, The Hub Karen,

Westend Towers, Westgate Mall, UN Office Facility among many others. For institutions and common buildings, a mention of any international school is most likely to evoke the name Laxmanbhai. These range from Brookhouse International School, Gems International School, Aga Khan Academy, Aga Khan University Centre among many more. For residential and apartments, the company is behind such projects as Garden City Residences, Laxcon Court, Bamburi Beach Homes among many others.

For Laxmanbhai, being the preferred contractor for these iconic projects has come by design and through years of pursuit of perfection. Notably, Kenya’s building and construction industry has over the past two decades witnessed significant growth particularly in the commercial and residential segments. Over the period, factors like aesthetics, breathtaking interiors, wide open space, recreation space among others are increasingly being incorporated in building to offer a wholesome experience. For most contractors, it is a challenge to deliver on every attribute beyond the structural aspect of the project. Indeed, the industry is awash with cases whereby clients have been forced to replace contractors midstream or redo whole sections. The case is different for Laxmanbhai. Through training of staff, commitment to detail and investment in the right equipment, the company has always delivered projects beyond the satisfaction of clients.

A case in point was the construction of the 20-storey Lonrho House, a project that was executed in the middle of the central business district while some of the occupants carried on with their businesses. Implementing the project was a monumental undertaking for Laxmanbhai. Despite the complex, delicate and dangerous nature of the job, the company did manage to complete the project in record time and within budget. “Lonrho House was a tough job but is among those that we are proud of delivering,” avers Mr Manji.

Partnership with Government in Affordable Housing

One area of opportunity that Laxmanbhai is determined to exploit is the government’s affordable housing project. This is based on the understanding that the government’s plan to build 200,000 affordable houses annually is not only timely but critical in addressing the severe housing deficit. More importantly, the plan will help address the problem of informal settlements by affording a majority of Kenyans with decent homes. As a company that believes in human dignity, Laxmanbhai intends to partner with the government to advance the

housing agenda. “The affordable housing plan is about the country’s socio-development and for that reason we intend to help the government to ensure the goals are realized,” explains Mr Manji. He adds the fact that the government is giving opportunities to local companies is something to celebrate.

Challenges

While Laxmanbhai is undoubtedly a force to reckon with, it has not been an easy journey over the past seven decades. Being older than Kenya, the company has witnessed the political and socio-economic transformation of the country, and contributing at every stage in the development of the construction industry. However, factors like economic upheavals, regulatory environment changes, onset of devolved system of governance among others have brought about significant impacts not only on Laxmanbhai but across the entire building and construction industry value chain. “Economic downtowns for instance make it difficult for clients to access financing for projects and this does affect us,” notes Mr

Manji. He adds that building strong shock absorbers, coupled by years of experience, has helped Laxmanbhai weather storms and remain on top of its game.

Ready for the Future

Having grown to become one of the powerhouse contractors in Kenya, Laxmanbhai is confident of the future. The company, which is involved in many corporate social responsibility projects including school feeding programs for the needy and employee empowerment, has no intentions to sit on its laurels. This explains why the company has continued to evolve with the building and construction industry in terms of technology advancement and particularly in the area of sustainability and green projects. “We continue investing in technology and training our staff on the latest developments,” notes Mr Manji. He adds the company is committed to continue enhancing its capabilities to ensure that it remains at the forefront of the industry by providing clients with world-class services.
