ROCKET LAUNCH Back in February, the launch of the Space X Falcon Heavy Rocket garnered global media attention. If Space X CEO Elon Musk realizes his vision, this rocket will eventually be used to establish a colony on Mars.

This will be a kind of celestial Noah’s Ark where one million lucky Earthlings will sit out the apocalypse of World War III, before sending their offspring back to repopulate the Blue Planet.

Inhabiting Mars is no slam-dunk for human beings though: diurnal temperature swings of 100°C; monumental dust storms that periodically engulf the whole planet; the lethal effects of solar flares; and an atmosphere so thin, that in places water boils at body temperature.

Even discounting the $90 million cost of launching the rocket, this will be an expensive enterprise.

The fanfare surrounding the launch at the Kennedy Space Centre, momentarily diverted my attention from a much softer, but for my money, more significant rocket launch taking place in Churchill Manitoba. Housed in a humble shipping container, Rocket Greens is bringing affordable fresh produce to the Canadian North for the first time.

Designed by Ottawa-based Growcer Modular Food Solutions, the installation of this plug and play hydroponic farm follows the success of six similar projects in Alaska. Testing at the Northern Studies Centre in Churchill confirmed the viability of hydroponic farming under local conditions, offering residents the enticing prospect of a reliable, year-round supply of fresh picked leafy vegetables and herbs.

Originally thought to be a break-even proposition, it now appears that Rocket greens can operate successfully on a subscription-based community agriculture model. Each $210,000 container is capable of delivering 450 portions of fresh greens per week at half the price of air-freighted produce, so generating an annual income of $40,000 per year.

This initiative has the potential to address the pressing issues of food security prevalent in the North, and at the same time, to provide much-needed local employment. Less glamourus for sure than the Falcon Heavy, this modest investment in Spaceship Earth, seems more meaningful – and paradoxically – more far-reaching than a mission to Mars.

As an architect, designing and building one’s own home is the quintessential challenge: to walk the talk while dreaming on a budget. Being in the position of clients gave my wife and me a new perspective on decision making.

By Javier Uribe

Despite the abundance of infill lots in Winnipeg, finding the right one was difficult. The City suspended its very successful Residential Infill Tax Credit By-law in 2011 and extended the fees for the Land Dedication Reserve to infill developments.

After six years of intense suburban development the City has recently introduced the Impact Fee By-Law to pay for the infrastructure costs associated with growth, but unfortunately it will soon be extended to include infill developments.

BUILDINGS-IN-REVIEW &

2017

Highlighting LEED®-certified buildings in 2017 MEETING CANADA’S GHG EMISSION REDUCTION TARGETS, ONE BUILDING AT A TIME Welcome to the eighth edition of the LEED in Canada: Buildings in Review supplement, produced in partnership with SABMag. In this supplement, you will read about some of the most innovative and efficient buildings in Canada. LEED certification provides a critical third-party seal of approval in the marketplace, and ensures that a building has gone through a rigorous process to verify their environmental performance targets.

Over the past 15 years, the CaGBC has worked with the industry to change the way that buildings are designed, built and operated making Canada home to the second-highest number of LEED certified buildings outside of the U.S., with over 3,400 LEED certified projects, and well over 7,200 registered projects across the country.

Last year was a big year for Canadian green buildings, with the launch of Canada’s first Zero Carbon Building Standard, growing recognition and support from governments across Canada, and a slew of new LEED v4 certifications and registrations. We also continue to expand our educational offerings and technical training via webinars and in-classroom sessions, as well as bringing you the latest ideas, information and innovation at Building Lasting Change, this year including the international WorldGBC Congress, taking place at Beanfield Centre in Toronto from June 5 to 7 – we hope to see you there.

The CaGBC is pleased to continue our work with SABMag in providing professionals and contractors, building owners and developers, and manufacturers and suppliers with the national exposure and recognition they deserve for being at the forefront of green building innovation. Thank you for your commitment and support for this supplement and congratulations to all of the 2017 LEED certified projects.

RIVER PARK AT UPTOWN MARKHAM

LEED SCORE CARD - PLATINUM

Markham-based real estate developer Times Group is pleased to announce River Park at Uptown Markham has achieved LEED® Platinum v2009 Certification.

River Park is a stunning ensemble of low and high rise condominium residences that have been constructed to the highest standards of sustainable design. To achieve LEED® Platinum Certification, River Park achieved 80 out of the total 110 LEED points.

The project is designed to save more than 50% in energy costs and reduce both interior potable water consumption and potable wastewater conveyance by more than 50% when compared to the LEED baseline for energy and water respectively. The energy efficient design at River Park includes a 29% window-to-wall ratio, efficient double glazed windows with hard low-e coating, argon, and thermally-broken frames. Amenity and in-suite ventilation systems include heat recovery. Efficient lighting is provided throughout the building, and common areas (including corridors) are controlled by occupancy sensors.

The building is also connected to the Markham District Energy Plant, further reducing both the project’s energy consumption and carbon footprint.

To confirm operational building energy use and water consumption is in line with design parameters, a measurement and verification plan is in place, including a comprehensive metering system and post-occupancy energy and water consumption analysis.

The landscape design at River Park achieved a 100% reduction in potable water for irrigation based on a drought tolerant design and an efficient irrigation system using captured rainwater.

Residents at River Park also benefit from occupant comfort-related features. These include in-suite heat recovery ventilators that provide fresh air directly to each suite along with fan coils outfitted with efficient MERV 13 filters. Each unit has programmable thermostats and a humidistat to monitor space comfort. Building finishes such as paints and flooring are low-emitting and with no or very minimal VOC content.

Times Group is an award-winning green builder and a premier name in the industry with over 30 years of business and a record of excellence across the real estate development spectrum of the Greater Toronto Area.

Every Times project is distinguished by an integrated planning process, a meticulous attention to detail and a commitment to enduring value.

Enhanced Commissioning practices ensured all mechanical systems were installed and function according to the project’s design intent, and operations staff are trained adequately to operate the building.

One York is a 35-storey, sustainability driven, class AAA office tower occupying a full city block just minutes from Union Station.

One York Street has raised the bar for commercial office properties in sustainability and workplace health.

The project pushes the envelope of high-performance buildings into the future.

Part of a larger two million sq.ft mixed used space, that includes two condo towers, a four storey retail podium, food hall and public space, this LEED platinum CS certified building has the highest score for a new commercial building in Toronto and the second highest in Canada with 89 points.

“At Sun Life, we hold ourselves accountable for managing our operating footprint while engaging our employees in environmental stewardship. Minimizing our energy consumption, and using less paper and less electricity during peak hours are among the few ways that One York continues to help us keep sustainability top of mind,” says Melissa Kennedy, Executive Vice-President & Chief Legal, Officer, Sun Life Financial, the building’s anchor tenant.

The building design and energy efficient systems translate to 46% energy consumption savings compared to a typical office building. High-efficiency technologies in the building include the Enwave district cooling system; a high-efficiency boiler plant, HVAC equipment, building automation controls, and occupancy/daylight sensors.

Floor-to-ceiling glass allows for maximum natural light, under floor air distribution provides improved air quality, and rainwater is collected from all roof areas including adjacent condos, to reduce water consumption.

This location promotes active transportation options like biking and walking to work: over 300 bike racks are located inside the building, with showering facilities and full onsite change rooms. The project’s design delivers a new benchmark for advanced human comfort and healthy office building design.

111 RICHMOND ST. W – LEED EB O+M: OXFORD PROPERTIES GROUP Oxford’s 111 Richmond Street West office building in Toronto is certified LEED® Platinum for Existing Buildings, recognizing the building’s environmentally progressive and efficient operations.

The heritage building already boasts the LEED® Gold Core and Shell Certification, achieved in 2013 after completing a full redevelopment.

The building is also part of the 2.4 million square foot RichmondAdelaide Centre, with two other buildings also certified LEED® EB and one slated to achieve the designation following its redevelopment.

The building pursued LEED® Platinum for Existing Buildings because of the direct benefits it delivers to its customers and community at-large. To achieve the certification, the team implemented physical and operational improvements to increase occupant comfort and satisfaction while concentrating on projects that would continue to improve energy and water performance.

Some highlights of 111 Richmond’s project include: - An ENERGY STAR score of 93, which means 111 Richmond is in the top 93rd percentile of energy efficient buildings in Canada.

- Installed efficient indoor plumbing fixtures and fittings resulting in 38% reduction in water use over the LEED baseline.

- 12% improvement in waste diversion rate from 2016-2017.

- 90% of 111 Richmond’s occupants commute via means other than single occupancy cars.

Designated with Grade 1 heritage status, the existing steel frame high-rise heritage structure had been abandoned for 19 years prior to its transformation into a LEED® Gold Certified School of Hospitality and Culinary Arts with 104 student housing units. The overall project scope consisted of remediation and renovation to the existing heritage tower, former banking hall and annex, as well as construction of a three-storey addition.

This adaptive re-use project within Winnipeg’s urban core exemplifies a sustainable approach with many of the typical strategies one would find in a LEED certified building including: a green roof; water use reduction; waste management during construction; the use of materials with low VOCs and recycled content; and a new mechanical system and renovated envelope which helped achieve 49% energy cost savings over MNECB.

Additionally, there were some unique sustainable strategies employed in the design of the addition, which houses the bulk of the mechanical and lab equipment. Here, the cooking laboratory energy from the Culinary Arts Program is recycled rather than simply being discarded: waste heat from the refrigeration systems is captured to heat domestic water as well as the pumps that heat and cool the student residence.

THE NEW JUBILEE HOUSE About the Jubilee House The original Jubilee House, an 87-unit social housing facility built in 1986, was owned by the City of Vancouver and operated by the 127 Society. The building was falling into disrepair, the structure was failing and maintenance costs were mounting putting a strain on the Society. In order to facilitate the relocation and creation of social housing in the downtown core, Brenhill exchanged its land across the street with the City of Vancouver and developed 162 brand new social housing units which created an additional 75 new units for the 127 Society.

With an uncompromising focus on quality, Brenhill collaborated with BC Housing, the City of Vancouver, the 127 Society for Housing and Terra Housing to build a new social housing facility for seniors in the downtown core – the new Jubilee House. The direct involvement of all parties throughout each phase of the project ensured that the daily needs of residents were forefront in design. The entire ground floor is dedicated to amenities and offices featuring several multi-purpose rooms, a library, computer room, kitchen and low-cost food store. Enhanced lighting throughout the building accommodates those with failing eyesight and two roof-top patios with edible gardens encourage community among the residents.

Upon completion in 2016, all existing residents were able to move right across the street to their newly completed, modern homes.

The additional low-end-of-market units assist the non-profit 127 Society in operating and maintaining the new building creating a self-sustaining model to meet the growing housing needs of Vancouver’s low and middle-income population.

The Jubilee House has raised the bar in seniors’ accommodation design and was awarded the 2016 Award for Excellence in Urban Development for Non-Market Housing at UDI’s bi-annual award ceremony.

MAISON ENERGECO The motivation behind Maison Energeco’s concepts is to build houses with high energy efficiency while avoiding the problems of traditional construction. Building a house in the factory makes it possible to better manage the elements that make up the house and, in any case, avoid the many back and forth on the building site, which implies a lower environmental footprint. In addition Maison Energeco minimizes the number of waste associated with the construction of its houses and sees the recycling of this waste.

Maison Energeco manufactures energy-efficient homes far exceeding the standards of the National Building Code. Houses certified to CSA-277-16, all Énergeco homes are required to be LEED certified; Innovation; Construction whose frame is ultra robust module easy to install and allowing flexibility of possible addition. Allows a green roof.

IS B.C.’S ENERGY STEP CODE A BLUEPRINT FOR CANADA? PHOTO: STEPHEN HUI, PEMBINA INSTITUTE.

Innovative building standard off to a promising start

By Tom-Pierre Frappé-Sénéclauze, Pembina Institute

In 2017, British Columbia introduced what might be North America’s most innovative beyond-code standard for energy efficiency. The B.C. Energy Step Code is an opt-in regulation that enables local governments to pursue improved levels of performance for new homes and buildings — creating healthier and more comfortable spaces that are more affordable to heat. It’s a promising experiment that could chart a path for the rest of Canada.

The Province created the framework in collaboration with industry, local governments, and civil society. But will local governments use it? Eight months after enactment, the answer appears to be a resounding “yes.”

The Energy Step Code allows cities and towns in B.C. to require or incentivize one of five levels of improved building performance, from current code performance all the way to net-zero energy ready.

Net-zero energy ready buildings are ultra-efficient; they could produce on-site [or nearby] as much energy as they consume over the course of a year — for example, by putting solar panels on the roof or on the canopy of an adjacent parking lot.

ADVANCING THE APPLICATION OF RENEWABLE ENERGY

IN ARCHITECTURE

This article outlines a two-tier design approach that can assist architects to achieve their goal of a Net Zero Energy building. The first stage is to reduce the overall operating energy demand of the building; and the second is to replace traditional energy derived from fossil fuels with energy from renewable sources.

Recent technological advances are making renewable energy options more attractive, both in terms of output and cost recovery. BY LOGHMAN AZAR

OVERVIEW Despite the technological advances, decreasing cost and a range of incentive programs for renewable energy, the most commonly used sources of energy in Canada are still fossil fuels and nuclear power, as both remain readily available and inexpensive.

Arguments in favour of nuclear power as a clean and renewable energy source overlook concerns about the safe disposal of radioactive waste, taking an ‘out of sight, out of mind’ approach to the long term implications of storage in deep geological repositories. Similarly, while research on CO2 capture and storage is ongoing, this is also a ‘tail pipe solution’ – one that endeavours to solve a problem that we now have the means to eliminate altogether.

Meantime, the impact of excess CO2 on climate change, including depletion of the ozone layer, polar ice melt, receding glaciers, warming of the oceans, and air pollution, among other problems , continue unabated. By contrast, renewable energy sources such as solar and wind are clean, with no harmful by-products - but they do require proper ‘technology’ and ‘design’.

ENERGY USE IN BUILDINGS Of the total energy consumption in North America, approximately

1

45% is used in the construction and operation of buildings. Commercial buildings account for 20%, single family homes for another 20%, and multi-family residential buildings a further 5%: Ironically, more than 85% of Ontarians are living in multi-family buildings, and numbers are growing. The remaining energy consumption is related to industrial and agricultural use [25%], and transportation [30%].

PAYING FOR ENERGY As with other commodities, we have traditionally purchased electricity or natural gas from suppliers and distributors and paid for our usage at market rates on a monthly basis. A more recent option, and a growing trend, is to become an owner-producer of on-site energy, using what one needs and selling the excess power back to the grid.

As the cost [particularly of photovoltaic technology] comes down and awareness rises, this option is becoming increasingly popular.

The challenge for architects is to integrate these new technologies in a way that maximizes their efficiency without compromising the other design goals for the project. This requires a two-tiered approach to design: the first step being to reduce the energy demand of the building to the greatest extent possible, and so reduce the amount of operating energy required; the second is to provide that energy from renewable sources in a way that is cost-effective and at the same time flexible enough to respond to future changes in the market.

The new school was designed to accommodate 60 Kindergarten and 450 grades 1-7 children, and was built directly above the existing two-level, below-grade parkade. The parkade required structural upgrades to meet the current seismic code and to support the new four-storey school above. Since the parkade is owned by the tower residents, the VSB had to reach an agree-

viewpoint LIVING BUILDING PERFORMANCE ON A BUDGET Launched in 2006, the Living Building Challenge is a rigorous certification program that sets absolute performance standards and requires proof that they have been achieved before awarding certification. There are seven categories [or petals], most comprising several imperatives, all of which must be met if recognition for that petal is to be achieved. Full recognition requires a building to meet the imperatives of all seven petals; partial recognition requires a building to achieve three petals, one of which must be Water, Energy or Materials.

By James Hettinger, OAA Most imperatives are objective and readily quantifiable: net zero energy, net zero water, construction carbon neutrality, for example; while others, such as Beauty, and some aspects of Health & Happiness, are more subjective.

As well – and perhaps most importantly -

the Living Building

Challenge is a philosophy and advocacy tool, to underscore the interrelationships of environmental, social and economics of how to design and build in harmony with the planet. Despite these laudable goals, uptake of the LBC has been slow, with only one project previously completed in Ontario.

The renovation of our 1,190 sf office in Burlington, ON was designed to the Petal Certified Renovation standards of LBC Version 3.0, achieving the Materials, Beauty and Health & Happiness petals. The office was designed to be energy efficient and a great work space, while providing the practice with a laboratory for testing and evaluating both the performance and cost effectiveness of new design strategies. Contrary to popular belief, the office design proved to us that the most sustainable solutions need not cost more than traditional

1

approaches to design.

An example was the creation of a super-efficient dry radiant heating and cooling system, using the existing HVAC equipment and precast concrete floors. This provided the highest return on investment, controlling the operating costs and providing a comfortable environment in all seasons.

This and other design responses communicate the firm’s philosophy to all who enter the office. With a capital cost of $80,000 [truly a developer’s budget] and EUI operating costs of only $40 per month, the project proves that a lower energy footprint and a healthy work environment can be achieved on a modest budget.
