Welcome to the Spring 2014 issue of Green Building & Sustainable Strategies magazine. This time around, below, we are reprinting an article courtesy of China-based Bisagni Environmental Enterprise (BEE), dealing with the subject of whether LEED leads to better energy performance. We find BEE’s article about the findings from an organization calling itself Environmental Policy Alliance (EPA) to be very intriguing. The tagline for the EPA website? LEED Exposed. The organization claims to reveal the truth about LEED – the building performance rating system

ENERGY SAVINGS IN BUILDINGS WITH LEED CERTIFICATION

he free-market group Environmental Policy Alliance (EPA) released some very unsettling findings regarding LEED: that the supposedly green buildings with LEED certification in Washington D.C. actually use more energy than those buildings that aren’t LEEDcertified at all. Does LEED really lead to better energy performance? According to the group, even the Washington headquarters of the USGBC, with its platinum LEED certification, scores 236 EUI (energy use intensity), compared to the average 199 EUI for non-LEED certified buildings in the capital. A difference of 37 EUI isn’t so big, but every watt counts when one is aiming for energy efficiency. If you ask physics professor John Scofield who runs ThePragmaticSteward blog though, analysis of energy use between one group of building and another is hard to do correctly and objectively, especially if the measurers are people “who begin the study with a stake in the outcome—either those promoting LEED or those ‘dug against it’.” Possible Shill Group vs. LEED Certification Which leads us to ask what the Environmental Policy Alliance has at stake in their report. We checked out their website, which looks pretty legit, but their LEED Exposed section is somewhat suspect—the page branches out into “evidence“ links as to why LEED is a waste of taxpayers money. A quick read of the articles inside points out the various criticisms that have been hurled at LEED time and again. LEED isn’t open for commenting from the general public, the science behind LEED is questionable, LEED .favors only one timber source, among other things. Some of the SPRING 2014

concerns might be valid, some obviously made out of spite. When a website however devotes all its energy to discredit LEED without so much as giving the other side of the story—what makes LEED effective, for instance—all their efforts appear tainted with a dark cloud of hatred and malice.

Questioning LEED Certification Shill group or not, Environmental Policy Alliance raises a few valid issues about LEED’s shortcoming as a green building certification that’s worth discussing. In particular, LEED’s weighted point-based system makes it easy for builders to pick and choose the easiest and most feasible points first, thereby securing for the project a respectable score. No doubt, this bonus point-hunting dilutes green building’s honest intentions, burying it in a flurry of metrics and technical specs. The builder gets busy on metrics, instead of ascertaining if those metrics actually translate into good building’s performance in real life.

As an example, the Living Building Challenge—an alternative to LEED, requires a full year of operation before verifying its energy and water performance, which is a pretty straightforward and sensible approach. In fairness to LEED 2009, its Minimum Program Requirement (MPR #6) gives owners the option to commit to sharing wholebuilding energy and water consumption data for up to five years beginning occupancy, although that too is a bit lax. Since it is just an option, owners can opt out if installing such meters is cost-prohibitive or impractical to install. MPR 6 Option 2 invites projects to demonstrate their commitment to high performance operations by pursuing LEED for Existing Buildings: O&M certification within two (2) years of accepting their design and construction certification. Although projects pursuing LEED EB: O&M are not required to complete the 5-year reporting period before achieving existing building certification, they will have to re-commit to MPR 6 for another 5 year period (or until their LEED EB:O&M recertification) when registering for LEED EB: O&M. (Bold letters ours.) Even the USGBC itself is accused of cherrypicking LEED energy data, since it only provides information for 450 out of the 1,861 buildings it has gathered data from. That only amounts to 24%, hardly reliable to get any definitive answer about the performance of buildings with LEED certification. We honestly want the best out of LEED and we’re glad LEED v4 is currently addressing that laxness in 2009. Because if it doesn’t, LEED risks becoming just a glorified brand, something builders use to attach to their project to garner prestige. LEED has to be more than just beautiful in theory and on paper. Green Building & Sustainable Strategies

China’s Eco-High-tech cities: towards an energy efficient community in Kunming

tepping out of your plus-energy house regulating the light and the temperature cleverly and automatically according to the sun’s path. Catch the vital energies of the nature by training ourselves Tai Chi Chuan or Qi Gong under a snow of cherry tree petals. Cultivate together with our neighbors the community vegetable garden. Harvest the organic vegetables for the family dinner. Wander between the marshes of rainwater harvesting and the recycling lagoons where the sky of koï carps is covered of lotus flowers. Swim in a naturally filtered swimming-pool. Admire the elegant and nagging axial wind turbines. Listen the laughter of children of the ecodistrict who share with their grandparents the games of Mahjong, Go and Cuju in the wild field. Recycle our organic waste in compost wells producing natural fertilizer. Sort out the other waste via a silent and underground pneumatic collection system. Go to work by electric bicycle or driverless car (Electric Networked-Vehicle), both recharged directly by the photovoltaic roof of the house. Follow the road whose sensory LED lights match according to sounds and movements of the city-dwellers. This is the Eco-High-Tech atmosphere of the “Flavours Orchard” project. It’s a pioneer project that fights for the conception of eco-responsible lifestyles along the Daguan river connecting the “Emerald”, the green lake of the city centre of Kunning, to the magnificent Dianchi Lake in the South. Capital of the Yunnan province, the city is located at 1894 meters high and benefits from a temperate climate all the year that gives to it the charming name of « The City of Eternal Spring ». The site of several hectares is an old industrial wasteland devoted to be restored in a new eco-district whose exemplarity in terms of sustainable innovations is supposed to be reproducible everywhere in China. The leitmotiv is to produce more energy and biodiversity than we consume by recycling at the same time our waste in reusable natural resources endlessly towards a post-nuclear, post-fossil and zero carbon emission city. Through the creation of such projects, China is recovering its delay on the ecological debt reimbursement and tries to slow down the massive rural exodus it suffers by the creation of new urban prototypes mixing all the advantages of the city and the countryside. 4 Green Building & Sustainable Strategies

THE FLAVOURS ORCHARD

CONSTRUCTION OF 45 PLUS-ENERGY (BEPOS) VILLAS IN A SMART GRID KUNMING 2014, YUNNAN PROVINCE, SOUTHWEST CHINA 45 PLUS-ENERGY (BEPOS) VILLAS PLANTED IN THE SMART GRID OF A COMMUNITY ORCHARD The building sector is a primary energy consumer particularly in China (40% of total consumed energy) in front of the transports (30%) and the industry (30%). It is responsible for more than 40% of total emissions of CO2.

It’s obvious that the energy savings are thus the major economic and ecological challenge for this sector. Whereas the prices of the fuel and the non-renewable energy increase unavoidably, the objective is to divide by 10 the consumption of this construction sector for an equivalent service within the next ten years. In this perspective, the concept of this new « Flavours Orchard » eco-district is to build SPRING 2014

45 Plus-Energy Villas in a huge community orchard/food garden integrating a Smart Grid self-managed by the gardener-inhabitants and the participants of the project. In the heart of this nourishing landscape, the goal is to associate a state-of-the-art for smart building automation systems and information integrated in each villa (leading to cost reduction and Increased functionality) with an intelligent energy network in order to redistribute the produced excess (electric, calorific, food) towards the nearest needs so as to prevent from the loss in lines or related to the storage systems. In addition to the fuel cells, the electric vehicles are also used as buffer storage of electricity excess produced by the solar roofs assuring thus the daily travels of the inhabitants for free. The objective is also to repatriate the production of the organic agriculture in the heart of the city, center of its consumption. This bio-geographical integration of the master SPRING 2014

plan respects the natural qualities of the site and maintains the continuity of the endemic ecosystems (trees, hedges, streams, floras and fauna are preserved). Flavours Orchard is a genuine garden sharing its energies designed and cultivated collectively. Ideas are here more shared than the ground, the sun or the wind because it deals not only with producing what to eat, lighten and air conditions but also to meet on a common ground of ecological experimentations and collective projects. It’s an urban landscape open to everybody without fence between the villas, in favor of the neighborhood relationships and the intercultural and intergenerational social links. It’s an educational tool about the environment respect thanks to its ecological master plan, its organic agriculture technics, its smart home automation strategies and its integration of renewable energies. The private garages for electric cars and

the technical rooms for home automation are located underground. This basement distributes each villa under the central path to liberate completely the orchard dedicated only to pedestrians, cyclists or electric driverless cars. The future families of these Plus-Energy villas will be able to live and work comfortably in their villa reinventing new eco-responsible lifestyles maximizing the normal living standards. The 45 Plus-Energy Villas produce more energy from renewable energy sources, over the course of a year, than they consume from external sources. This is achieved by using large North and South facing window areas to allow sunlight to penetrate the structure, by reducing the need for energy use from air cooling units and light bulbs with triple-glazed windows, and by the addition of heavy insulation that means the structure is already warm in the evening and therefore needs less heating. These passive buildings (BEPAS) that capture heat during the day in order to reduce the need to generate heat over night, exceed their energy needs through renewable energy production by the integration of solar photovoltaic and solar thermal panels, geothermal heat exchangers, and combined heat and power units (CHP). All grey water is recycled in lagoons for agricultural irrigation and toilet flushing. All waste water will be sent to bio-reactor facades (with panels filled with algae) for anaerobic digestion and the methane emitted during the digestion process will be used to produce energy and to cool the interiors. The construction of positive energy constitutes a high technological and conceptual rupture. These villas are thermally insulated without discontinuity and without thermal bridges. They are airtight, present controlled ventilation and are also equipped with economical domestic appliances of A+++ class. They generalize the LED lighting with automatic detection of presence and needs. They have a total consumption of primary energy (heating, sanitary hot water, lighting, all appliances) estimated at less than 50 kWh/m2/year for an average production that can reach 100 kWh/m2/year via the sun or wind. According to the usage of inhabitants, the consumption of primary energy could even decrease under 35 kWh/m2/year. The 45 villas building with a wood/steel structure are divided into three architectural typologies forming thus 3 eco-districts having their own identity. Green Building & Sustainable Strategies 5

THE “MOBIÜS” VILLA

he Mobius Villa is organized around an endless ribbon drawing the symbol of infinity around two patios, one aquatic and the other planted. This ribbon with primary steel structure and secondary wood frame is built from the repetition of one trapezoidal module repeated 24 times in the space. This module, opened at 30 degrees forms thus a pedestrian sloping path of 720 degrees along its double revolution. It contains all the bedrooms, the bathrooms, the offices, the libraries and the game rooms. It is covered by a green roof, true suspended vegetable garden with high thermal inertia and with a zenithal photovoltaic glass roof. The curved geometry forms a snake in sustentation on top of a façade in “8” with supporting frames. Louvered shutters in translucent glass pivot automatically along this glass facade to regulate the solar inputs during the day. The panoramic ground floor aims at immersing the diurnal life spaces in the heart of a clearing coiled in the orchard. The living room, the kitchens and reception rooms are located around the central vertical axis of the project. Actually at the intersection of the double loop, the vertical circulations distribute the 4 inhabited levels and the garden roof.

THE “MOUNTAIN” VILLA

he Mountain Villa opens out at 180 degrees such as a huge Chinese fan built from east to west to ideally follow the sun’s path. It’s a double-skin architecture presenting a south facade very glazed and a very opaque north façade in wood presenting 20% of perforation. The 22 arches are linked together by cables. They are closed by solarized photovoltaic glass panels. Panels filled with algae are also integrated to the conception in the 7 central arches to produce bio-hydrogen. The second exterior skin develops a glued laminated timber frame and works as a huge windscreen shaped in wood lace. This trellis enables to assure the intimacy of the inhabitants and to regulate the inputs of heat by subduing the solar rays from east to west. In the center of the villa, an atrium full of light raises on 4 levels. A spiral staircase coils around a panoramic glazed elevator to distribute all the night and relaxation spaces. The living rooms and reception spaces are opened towards the landscape by a big arch going through the North and South facades.

Green Building & Sustainable Strategies

THE “SHELL” VILLA

he Shell Villa liberates itself from the ground on its 6 stainless steel pillars to stretch towards the sky and to make its axial wind turbine higher than the top of the fruit trees. A circular deck takes the loads of a glued laminated timber carpentry that is plaited in diamonds such as a conical Chinese hat. It’s a cocoon villa drawn in double curves and organized around three patios in spiral that fit closely the membranes of the twisted wood beams. These patios are isolated by the glass façades whereas three stainless steel petals put on insulating cushions coat the structure from outside. This radiant wood structure is divided into 36 standardized beams that are spaced out from each other by 10 degrees from their center. Thus, from the life spaces we obtain panoramic views on the whole orchard whereas an elevator goes through all the levels to the top of the mast of the axial wind turbine. These three typologies of Plus-Energy Villas set up in the clearings of the great community orchard are the symbol that it is possible to invent new contemporary models of eco-responsible housing mixing the economical evolution in China and the worldwide respect of the environment. The precursory inhabitants are linked together by their citizen commitment for a new ecological ideal that is energetically efficient, collective and sustainable. Through Architecture, the social life between city and countryside is first of all reinvented!

“We follow up in a year or two. Is the customer happy? Are they as comfortable as they thought they would be? We believe the measure for success is whether the system is performing as planned, or better. It’s about achieving performance and comfort. Doing that comes with experience and we have a lot of that.” Besides having a full line of residential and high performance commercial product available, GeoSmart also prides itself on ingenuity. “We have the right products for virtually any project,” says Brezynskie, “but when it comes to the heart of the system – the outside loop – we have been quite innovative.” One example is how GeoSmart decided to create a unique identity for geothermal ground loops about 10 years ago.

“Gas pipe is yellow, sometimes orange, and almost everything else is black,” he says. “That’s what most of our competitors use – black. But not us, we created green geothermal pipe. That’s what colour it should be. If someone is digging and they hit a green pipe, now they know what it is.” But GeoSmart didn’t stop there. “We looked at the material the pipe was made of, as well, and improved on that. The industry always used PE3608. It’s a pretty good resin, very good at handling pressure and temperature change and transfers heat fairly well. “But our green geothermal pipe uses PE100. It has all the same properties [high density polyethylene] of the previous generations of resin, but with dramatically higher strength.

This means we can use a thinner wall, and still have a higher pressure rating, all the while achieving better heat transfer. “So all of our pipe is green and is made of PE100. It’s the best.”

INNOVATIVE GEOSMART ENERGY EARNS SOLID REPUTATION FOR EXPERTISE AND KNOWLEDGE By Greg McMillan

here’s an adage used by sports teams that goes something like this: You’re only as good as the players around you. In many ways, that same maxim applies to the business world. And a specific example can be found with GeoSmart Energy, one of the largest non-manufacturing based distributors of geothermal heating and cooling solutions. How does the GeoSmart team push the envelope? They make sure their geothermal specialists and their customers have access

to the most effective and efficient geothermal energy products and services available on the market today. “GeoSmart Energy is a brand of geothermal heat pumps,” says Chad Brezynskie, VicePresident, Sales & Marketing, GeoSmart Energy. “We are a privately-owned Canadian company with a grassroots team that has come from the trenches. And we have an amazing group of contractors on our team.” Brezynskie tells Green Building and Sustainable Strategies magazine that the contractors, in fact, allow GeoSmart to pull away from the field.

“They are the ones that do all the hard work. They take our product to market and we appreciate every opportunity they give us to work with them on a project.” GeoSmart, Brezynskie says, separates itself from competitors by only working with a select group of contractors, then supporting them from design to project completion. And that could also involve collaborations with architects, engineers and building owners. “It’s not just geothermal, it’s highperformance geothermal,” he says. “Just about anyone can make it work, but that shouldn’t be the measure of success.

The cost and energy-efficiency of geothermal is also a big selling point, he says. “We can reduce a building’s cooling cost by 50 per cent and that can be a huge saving in a large office building. And heating costs for a rural home using propane or oil can be reduced by up to 75% with geothermal. It’s huge.”

The GeoSmart team sees a lot of different construction methods and architecturallychallenging projects, however Brezynskie says any uniqueness is never especially daunting. “We can always integrate into the environment seamlessly,” he says. “That’s the thing about selling comfort, it

just needs to be there … all around you. You can’t see it or hear it, it’s just there.” www.geosmartenergy.com

The goal of the ASH, built by the Toronto Region Conservation Authority (TRCA) and the Building Industry and Land Development Association (BILD), was to educate the public, builders, and housing industry professionals about leading-edge building practices and products and how they could be used to create sustainable homes and communities. The house has achieved some of those objectives, as well as providing invaluable research through energy and water monitoring by universities and colleges in partnership with

Canada’s leading opportunity to showcase innovation in sustainable construction Green Building & Sustainable Strategies

The ASH, actually two semi-detached units at the Living City Campus at Kortright, is one of the most efficient renewable energy houses in North America. One showcases the best green building practices available, while the other highlights up-and-coming technologies. Features include solar photovoltaic roof panels, a wind turbine, in-floor radiant heating, heat and energy recovery ventilators, low-VOC finishes, waste-water recycling and drain water heat recovery units. “Not only were these two semi-detached houses to be a showcase of the best in green building technologies, but we also wanted to learn what works best and how they can be

configured to optimize costs and energy performance,” says Larry Brydon, who was on BILD’s board in 2007 when the decision was made to construct the twin houses, and served as BILD’s project manager. In 2005, a national design competition, sponsored by TRCA (which operates Kortright) and run by the Design Exchange, called for a four-bedroom home designed for mass production, that had innovative waste-water treatment and would meet LEED Gold (Leadership in Energy and Environmental Design) and Energy Star standards. The design had to be flexible to allow for intensification. The winning design, Building Blocks, was created by a Toronto team that included Anne

Stevens (FORT Architect Inc.), Clelia Lori (Iori Architects) and Terrell Wong (Stone’s Throw Design). They designed modules that could be combined to create singles, semis or townhouses and to accommodate varying family size. They submitted the idea for two semis, 1,800 and 2,300 square feet. The design allowed for factory manufacture and site assembly or for conventional on-site framing. In 2010, the house was awarded LEED Platinum status. Half a decade later, the TRCA and BILD are looking at what has been learned, and how that information can help improve sustainability in the residential construction sector. This has been facilitated by instrumenting the house as a laboratory with over 300 sensors that feed into a state-of-the-art data acquisition system. Many technologies have been installed so they can be easily replaced or reconfigured as newer, more advanced options become available. Data collected for analysis includes: air temperature, relative humidity, and volumetric flow rate; water temperature and flow rate; natural gas consumption; solar radiation; and power consumption of individual components. It is among the most comprehensive residential energy monitoring projects worldwide. The most important lesson is not so much about the houses, but how the systems integrate, according to David Nixon, monitoring coordinator for STEP. “Often an electrical or mechanical device will have a performance rating that gives the buyer some sense of how efficient the device is and the savings that can be achieved by using it,” explains Nixon. “But when these are installed as part of a system, the performance can change significantly.” One example is the heat recovery ventilator, installed to ensure an adequate supply of fresh air in the well-insulated house. As a stand-alone system, the HRV is meant to minimize heat loss, but when coupled with the air handling unit, the fan was forced to run at higher than optimal speeds, resulting in wasted energy. “Balancing the system at low fan speed would provide better fresh air distribution at lower energy cost,” says Nixon. “There is a simple solution, but experimental research is needed to standardize an approach that will work best in a variety of different contexts.” Dr. Alan Fung from Ryerson University’s Department of Mechanical and Industrial Engineering worked with two of his students to develop the matrix for selecting technologies to be installed in the house and has supervised more than ten graduate students who conducted research there.

SPRING 2014

Archetype Sustainable House Gardens, part of The Living City Campus at the Kortright Centre

“What really sticks out in my mind is the research we did on the variable capacity air source heat pump,” says Fung. “We didn’t expect to see such high performance during the winter, especially at low temperatures. The heat pump operated for most of the heating season on part load, at a performance level that was well above the rated capacity.” Public tours and education programs target homeowners, students and professionals/trades in the building industry. Alex Waters, senior manager of the Living City Campus, says that over 10,000 students, 2,000 professionals, and 2,500 homeowners have toured the ASH and it has been used for consumer workshops such as eco-home renovations, efficient heating systems and DIY solar. “The response has been very positive,” says Waters. “People like that they can see the latest in green building design and get unbiased advice as to what works and doesn’t. Visitors love the open concept and the amount of space these small footprint houses have. The most surprising comments concern the renovationready attic and the one switch which turns off all the lights in the house.” The success of the ASH and other technology demonstrations contributed to the British Research Establishment’s (BRE) decision last year to select the campus to be Canada’s Innovation Park, part of the BRE Innovation Parks SPRING 2014

Network across the globe. This will result in the construction of up to eight more low rise buildings next to the ASH that showcase innovative construction and low carbon technologies, and demonstrate integrated designs that are practical and affordable. If you are a fan of sustainable approaches

and design, that really will be something to see. For more information about the ASH and five year anniversary event in June, visit www.livingcitycampus.com Tracy Hanes is a freelance writer. Tim Van Seters manages the TRCA’s Sustainable Technologies Evaluation Program

arden Bridge is a planned stunning new public garden and pedestrian crossing over the River Thames in London, England. Designed by London 2012 Olympic and Paralympic cauldron designer, Thomas Heatherwick and inspired by actress and campaigner, Joanna Lumley, star of Ab Fab and The Wolf of Wall Street, the Bridge will provide a vital new route between north and south London and feature plants, trees, woodland and meandering walkways to be used and enjoyed by all. As one of the greenest cities of its size in the world, this precious new piece of landscape will add to London’s rich and diverse horticultural heritage of heathlands, parks, squares, al-

lotments and community gardens and support many indigenous river edge plant species. With a structure that widens and narrows across its span, the elevated garden will not only be a safe and easy way for London’s many commuters and visitors to cross the river, it will also make places along its length for pedestrians to stop and better enjoy the remarkable river setting and unparalleled views of the city. The addition of careful planting with variety in scale, openness and intimacy will create a new kind of public space in the city. Heatherwick Studio is currently working closely with Transport for London and world-renowned engineering consultant Arup to develop the scheme. Arup is the lead

consultant on the project, covering all the key engineering aspects of the Garden Bridge, as well as environmental consultancy, transport planning, landscape design support and project management services Led by The Garden Bridge Trust, its groundbreaking design will integrate a new kind of public space into the fabric of the city, adding to London’s rich and diverse horticultural heritage. The bridge will cost about £150million to design and build, which is being raised by donations. Following the public consultation ground will break in 2015. Completion of construction is expected for late 2017 and the opening for Summer 2018.

What will The Garden Bridge achieve? The Garden Bridge will provide social, economic and environmental benefits on several fronts, some directly financial and others cultural and non-market. Briefly summarised, these are as follows:Improved pedestrian connectivity and amenity: Many of the existing bridges that span the River Thames prioritise vehicles, the Garden Bridge is designed for pedestrians. The Garden Bridge will provide a new public pedestrian route away from cars and vehicles between Temple, the Strand and South Bank. This will encourage a modal shift to walking which contributes to congestion relief, improvements in health and environmental quality. There will also be a reduction in journey times for some journeys. Benefits of new urban garden: the provision of a new and unique central London open space has an intrinsic utility and amenity value. Providing a new green and open space for all to enjoy will further enhance the standard of living and cement London’s reputation as one of the leafiest capital cities in the world. The Garden

Bridge will add to London’s rich and diverse horticultural heritage of heathlands, parks, squares and community gardens. Wider development effects: the Bridge will stimulate and support development on both the north and south banks, helping to attract new investment and supporting the transition towards higher value uses. By breathing life into and raising the profile of the north bank area (already the subject of a Business Improvement District) and increasing footfall to an estimate of up to 7m users a year, the Bridge will support development of this area to be realised. Increased visitor numbers creating economic growth in London and the UK: the Bridge will be a world class asset, with all of the potential of the Highline in New York, to feature in global marketing of the UK as a visitor destination – as well as enhancing the perception amongst international investors. This further increase in activity and footfall will lead to the development of complementary activities and uses that will generate jobs in the local economy on both sides of the river. The impact of increased tourism numbers

(specifically attributable to better connected attractions) and tourism spend will be felt both in the local area and in the wider UK as London acts as a gateway. Supporting the UK’s creative sector: the Bridge will enhance the connections between two cultural and creative clusters of international renown: Covent Garden/Aldwych (including the Royal Opera House, West Central theatres, Somerset House, King’s College etc) and the South Bank (including the Royal Festival Hall and South Bank Centre, National Theatre, National Film Theatre and Rambert Dance etc). Showcasing UK expertise and innovation in engineering, design and landscape: the visionary concept of the Bridge and its very high quality design, led by three UK firms, will create a unique and iconic structure that will become recognised worldwide, showcasing expertise in design, engineering and landscape, and supporting the UK and London’s international profile as a centre for the creative industries and its claims as thought leading capital of the world.

LEED AND GREEN GLOBES - A COMPARISON HVAC Design has Changed Forever

By Jiri Skopek AA Dip., OAA, MCIP, RIBA

ith the sudden re-emergence of Green Globes as a recognized green building rating system, practitioners may be wondering which system

to use. Just as all homo sapiens originated in Africa, all the green building rating system have their origin in BREEAM, hence it is not surprising that most rating systems focus on the same basic issues: site characteristics, energy and water consumption, the use of resources/materials, and the indoor environmental quality (IEQ). Both systems are recognized and accepted in Canada by the Federal Sustainability Strategy and several Provincial Green building Policies, and in the USA by General Services Administration (GSA) and other agencies of the Federal government, as well as many state and local jurisdictions. Compared to LEED, there is little doubt that the Green Globes brand has been poorly marketed. LEED, on the other hand, has been powered by US marketing savvy and has become the dominant, recognized label. As such it has been an influential advocate for sustainability in the built environment and inspired a green vision for the industry. In Canada, LEED continues to have a great success in reaching new construction market, whereas Green Globes has been more prominent in the existing building market under the BOMA BESt brand. Both rating systems have been recently updated. The newest version of LEED (v4) was rolled out at Greenbuild 2013 and features increased thresholds in energy, water, waste and IEQ; a new Location and Transportation credit; and a requirement for environmental product declarations and material ingredient reporting. Green Globes released its new NC (New Construction) update earlier this year in both Canada and the USA, which is largely based on the ANSI/GBI Standard 01-2010: “Green Building Assessment Protocol for Commercial Buildings”. The two systems differ primarily with re-

spect to materials, energy and quality assurance of the building envelope. Both systems recognize environmental product declarations and material ingredient reporting, but in addition, Green Globes also requires Life Cycle Assessment of the building assemblies, which captures the carbon content of the materials.

On the energy front, Green Globes’ energy modelling is reported and scored in terms of carbon, so that for jurisdictions set on putting the building on carbon diet, this is a plus. LEED deserves credit for pushing the envelope and spear-heading innovation and the launch of new products and materials. However, there have been some concerns that out of the dozens of innovative green building materials that are hitting the market, some may not have had the benefit of sufficient testing, possibly leading to building failure or lower than expected performance. This has been known to result in contractual, legal and technical risks sometimes associated with green buildings.

The ANSI-based Green Globes approach avoids this by putting a high emphasis on the quality of building envelope design and construction, with criteria that focus on specific areas related to envelope design and installation best practices. The updated Canadian Green Globes has also introduced new innovation credits not dissimilar from the Living Building Challenge, which focus on the positive contribution that buildings can make to the environment and the communities where they are constructed. This signals a departure from the status quo in green building industry, which has generally been more focused on reducing the negative impacts of buildings. Whereas high profile projects may absorb the higher cost of LEED certification, Green Globes may be the preferred option for projects that are primarily interested in cost effectiveness and ease of use. In the final analysis, both products are good because they get more people to do green building. Jerry Yudelson, the new head of the US organisation the GBI which promotes the Green Globes in the USA believes that there is value in both systems, saying, “There is plenty of room in the marketplace for more than just one rating system and competition is healthy.” SPRING 2014

And because it’s modular and installed indoors, there is no need for cranes or heavy equipment. In fact, our new 575V VRF system is so compact it is easier to incorporate into any design, plus it is less expensive to install and maintain.

Mitsubishi Electric’s new water-source, 575V VRF system is a game changer.

The Kortright Centre for Conservation (Maple, Ontario) Cathedral Court Co-op (Toronto, Ontario)

It uses ozone friendly R-410A refrigerant and is one of few heat pumps that can provide room comfort when outdoor temperatures drop to -25°C and beyond. Enermodal, one of Canada’s largest green building consulting firms, sought LEED certification in its construction of its new 22,000-square-foot headquarters in Kitchener, Ontario.

Enermodal chose the City Multi VRF which used only 70 kWh/m_ over a 36-month review period (the Canadian average is 375 kWh/m_). The building has been awarded three LEED platinum certifications and consumes only about 15% of the energy consumption of a typical Canadian office building. In another example, MrSlim™ M-Series ducted SEZ/SUZ split system was used in 2013 to retrofit downtown Toronto’s Cathedral Court Co-op. The MrSlim™ M-Series is a single or multiple split system that provides cooling when

outdoor temperatures are as low as -10°C and heating when outdoor temperatures are as low as -25°C. This solution was chosen given its energy sustainability, lower carbon footprint, ease of maintenance and overall reliability and longevity. This solution has performed exceptionally well, with no problems or failures of equipment during Toronto’s 2014 winter season with temperatures of -31°C and beyond. Mitsubishi Electric’s Zuba Central is a premium electric air to air heat pump that provides both heating and cooling.

It has a high efficiency ECM motor, uses ozone friendly R410A refrigerant and produces no CFCs or HCFSs with no Ozone Depletion Potential. It is an Energy Star qualified heat pump with S.E.E.R. ratings up to 15.0 S.E.E.R. in cooling mode and HSPF ratings of 9.4 in heating mode. Zuba Central was the subject of a performance assessment at the Kortright Centre for Conservation in Maple, Ontario, in conjunction with the Sustainable Technologies Evaluation Program (STEP) from Ryerson University. It was found to be a more cost-effective alternative to geothermal systems and a more energy-efficient alternative to conventional HVAC systems, exceeding EnerGuide ratings across all measure indicators. Aside from its long standing representation

of Mitsubishi Electric products, Mits Air’s new alliance with Aermec fits perfectly with Mits Air’s high-end, energy efficient product lines. Aermec demonstrates its commitment to the environment by continually meeting global energy savings and environment protection challenges in the development of their new technologies. All Aermec products available for North American applications use R410A, an ozone friendly refrigerant with a high

thermodynamic efficiency that leads to, together with the use of multiscroll technology, a reduction in CO2 emissions. The savings obtained when using Aermec for cooling in the summer, heating in the winter, providing domestic hot water, and recovering energy year-round, result in a 35% reduction in CO2 emissions compared to traditional R407C heat pumps and standard chiller and boiler systems. As for materials used for the piping systems, Vesbo PP-R pipes and fittings incorporate a fusion weld process to cover a wide range of applications. Known as an “all one piece” of material, Vesbo products are manufactured from polypropylene random copolymer resins, known as PP Type 3 raw material.

With an inherent layer of fibreglass incorporated in the pipe, typical insulation thicknesses can be greatly reduced as well. Two of Aermec’s products that have attracted much attention in North America are the NRL air to water heat pumps and chillers (13-260 tons) and the NRP multipurpose air cooled units with axial fans. The NRL units have been used in several successful case studies, including British Columbia’s Surrey Memorial Hospital, where three NRL3600 chillers with total heat recovery were installed to provide 750 tons of cooling and free/recovered heating all year round – thereby reducing energy and environmental costs. Aermec’s NRP is North America’s only simultaneous

heating and cooling unit with full heat recovery. With TER or COPs of up to 9, one can obtain great energy efficiencies while benefiting from any amount of heating or cooling, whenever it is required. Among other applications, the NRP is being used in the BC Hydro Northern Regional Operations building in Prince George, British Columbia, where two multipurpose heat pumps NRP700E4R2 with COPs twice as high as traditional chiller/heat pump systems will be used to provide unmatched energy-efficient and environmentally friendly heating and cooling. In 2014, moving ahead, the goal for Mits Air

is to increase its market share by enhancing its product offerings, building its employee team, and obtaining greater exposure to both Canadian and U.S. markets through trade shows, e-communications and the use of webinars and other related e-products. At the heart of it all, one constant remains: for difficult heating, ventilation or air conditioning (HVAC) jobs, the team at Mits Airconditioning Inc. will not only embrace the challenge, but will design an efficient solution that meets the needs of each individual client. www.mitsair.com www.aermec.ca www.aermec.us

WHEN THE CLASSROOM BECOMES THE TEACHER ECO-FRIENDLY PORTABLE FEATURES IDEALS OF HEALTH, SUSTAINABILITY AND ENERGY EFFICIENCY

t’s probably safe to say that it’s a rare occurrence when parents, students, educators, school administrators, custodians and maintenance personnel are all on the same page. But that will almost certainly be the case when they begin talking about a new unique portable classroom called a mobEE (mobile eco enclosure), a learning space containing ideals of health, sustainability and energy efficiency. Commercialized by Evolve Builders Group, the mobEE is a unique portable classroom constructed with an array of techniques spanning from natural and renewable materials to ultramodern design and high-tech features. In fact, the portable classroom merges super green straw bale building and other natural building techniques with state-of-the-art construction technology. “Parents and educators will find much to their liking about mobEE; mobEE is a place of learning where the building itself is part of the lesson,” says Ben Polley, founder of Evolve Builders Group. “Moreover, mobEE provides a natural, safe, healthy environment for children’s well-being. “Administrators, custodians and mainte-

mobEE Model “G” with linoleum floors, LED lighting and optional blackboard and heat exchanger packages.

nance personnel will similarly be enthused by mobEE’s benefits,” he continues. “No-wax floors simplify cleaning and maintenance and the durable permanent-quality construction provides exceptional life-cycle cost benefits. “And given the (Ontario) Green Energy Act’s requirement for all school boards to now publish the energy intensity of each school, mobEE may provide an affordable way to meet provincial efficiency targets. “Schools may never have another opportunity to meet so many goals with one easy decision.”

Standard mobEE features include: Fire resistant straw bale insulation; Glass viewing window into wall core; Structural insulated panel floor and roof; Fibreglass-framed high-efficiency windows; Natural, vinyl-free, waxless, antimicrobial linoleum flooring; • Mineral-based wall paints, in and out; • LED warm-white light fixtures; • Wood soffit with natural finish; • And steel roof with recycled content or low emissivity white roof membrane. After participating in the design and/or construction of three separate two-classroom permanent schoolhouses built similarly to mobEE, Evolve worked in conjunction with the facility department at the Upper Grand District School Board to craft this highly-functional, affordable, healthy portable. Polley says this is an example of the type of partnerships where academic researchers and industrial designers frequently seek out Evolve’s experience and participation. Evolve’s involvement at the pre-commercialization stage with large and trusted institutions is both an acknowledgement of Evolve’s diverse capabilities and helps contribute to its ability to propose the best solution for their clients complex needs, says Polley. “Few builders are so involved in the making of the industry, not just the making of buildings themselves,” Polley says.

HUMBER RIVER HOSPITAL

THE FUTURE OF HEALTHCARE: LEAN, GREEN AND DIGITAL

n 2008 the Ministry of Health and Long Term Care (MOHLTC) approved funding for Humber River Hospital (HRH), to begin the planning and design of a 167,300 sm (1.8 million sft) acute care facility on a dense urban site in the middle of Toronto’s North York region. The objective was to combine on one site the services and patient care currently being delivered at three different sites. With this goal in mind Infrastructure Ontario (IO) and HRH partnered to achieve the largest hospital in Ontario and second largest in Canada. As a major capital project IO and HRH began the process of procurement through the Public, Private, Partnership (P3) delivery model. HRH envisioned creating a hospital founded upon a “New Model of Care”; while remaining firmly rooted in the diverse community the Hospital serves. For HRH it was important that the new facility’s design not compromise the health of building occupants, the surrounding community and natural resources. HOK Architects Corporation (HOK) was entrusted with realising HRH’s vision as the Planning, Design and Compliance (PDC) Architects, responsible for establishing the guidelines and SPRING 2014

performance requirements that informed the design of the building. HOK is an industry leader in both Healthcare and Sustainable design; bringing to the project leadership in planning and systems development, and a focus on developing a holistic sustainable vision for the overall site. HOK led HRH’s staff and physicians through a comprehensive planning process to develop the specifications, and create a test design establishing innovations and strategic direction for the new Facility; characterized by Lean, Green and Digital principles. Although these principles address different aspects of the hospital’s operations and development they are intertwined; enabling the hospital to provide best quality service to the community while being a thoughtful local neighbour, supportive employer and responsible health and wellness citizen. After an extensive P3 award competition, Plenary Health Care Partnerships was hired as the DBFM team, responsible for the design and construction of the hospital, as well as building maintenance, life-cycle repair and renewal, and project financing. The Toronto-based Plenary

Health Care Partnerships team includes: Plenary Health and HCP Social Infrastructure (developer), PCL Constructors (construction), Johnson Controls (facilities management), RBC Capital Markets (financial advisor), and HDR (architecture). HDR, a global design firm with four offices in Ontario, is the delivery architect, responsible for translating HOK’s guidelines and performance requirements into the hospital that is being built today. The hospital site is located on the former parking lot of a government services campus; with residential neighbourhoods to the north and major arterial expressway to the south. The planning team met the challenge of providing within a 10.5 hectare (26 acre) site a 167,300 sm (1.8 million sft) new home for a broad range of health care services; while creating efficient, ready access for patients and staff. HRH 656 bed Facility anticipates receiving 136,000 ER visits, 5,300 births, 192,700 ambulatory visits and 40,700 surgeries each year. To accommodate such large volumes of visits to HRH’s services within the site’s size confines HOK proposed to leverage cutting edge technologies and planning concepts. Green Building & Sustainable Strategies 33

Business cases for automated supply delivery systems utilizing robots, complex pneumatic transport of soiled laundry and linen to external haulage units, and the use of a pneumatic tube delivery network are just some of the features that HOK and HDR implemented to achieve efficient healthcare operations. As a result of these lean initiatives, Barb Collins, HRH’s Chief Operating Officer, believes that the hospital is “on track to save 164 kilometres per day of walking time, with a potential savings of $2,000,000 per year in operating costs.” Another key strategy is the HOK-developed “Portals of Care”. Similar to an airport drop off this concept allows visitors to access HRH’s services effectively and intuitively at specific drop off points; channeling traffic flow according to desired destination. Compared to a traditional hospital the separation of access to different types of services (like ER, dialysis, ambulatory and inpatients) enhances accessibility for the community, boosts efficiency and gives HRH the ability to manage pandemic incidences without shutting down all services. The cumulative result of HOK’s strategic approach to planning and internal supply delivery is the optimum use of site conditions to achieve a large, complex, state of the art hospital on a tight urban site. Some of the most advantageous impact HOK’s contribution has had on the realiza34

tion of the hospital are the sustainable strategies focused on Facility energy consumption. Recognizing that a healthy environment is intrinsically linked with wellbeing, HOK and HRH set forth to minimize the new hospital’s energy footprint and reduce its yearly operational costs. Hospitals are one of the most challenging building types; with “24-7-365” activity, strict indoor environment requirements and occupant safety demands that result in power intensive systems and equipment. With this in mind the HOK team designed

hospital systems with focus on the implementation of energy recovery measures, leading-edge systems design and efficient operational protocols; using typical industry means and methods. At the same time the goal was to maintain 100% fresh air delivery to all areas of the hospital, optimizing indoor air quality. An integrated design group (including HRH, HOK, The Mitchell Partnership and Mulvey & Banani International Inc.) set a target of 40% energy cost reduction from the base case in ASHRAE 90.1 2007.

stakeholders and the consultant team have made possible the reimagining of a hospital’s mandate and the site’s potential. The result is a highly

sustainable health hub for the community and City; setting a new standard of care that balances social, financial and environmental wellbeing.

Nine months of research (using energy modeling, test design inputs, cost verifications and a concerted focus on enhancing conventional systems to reduce energy use) proved that 40% energy cost reduction could be achieved for this building type and size. Despite doubt from the Proponent Consortiums, HRH and HOK were confident in the research and that their vision could be attained. And although construction is ongoing, the DBFM team is expecting a 41.8% energy cost reduction over the ASHRAE baseline. To ensure that the sustainable innovations and targets were met once the project was released to the bidders, HOK specified in the bid documents that 15 points were to be achieved for the LEED® Canada-NC 2009 Credit EA - Credit 1: Optimize Energy Performance. Sample test design and energy model data equating to 40% energy cost reduction was included to guide the bidders. In addition the consultant team specified essential requirements based on the research test design; examples being the delivery of reduced air velocities and the utilization of waste heat, while leaving enough opportunity for market and industry value assessments. To ensure success HOK worked with IO to implement the Energy Guarantee Letter; an aspect of the Project Agreement between HRH and the winning Project Company Consortium that stipulates a specific energy usage in the 30 year Facilities Management contract. Where the LEED Credit EA – Credit 1 targets energy costs, the Energy Guarantee Letter targets actual energy use and is not impacted by the fluctuation of energy prices. In HRH’s case this leads to a 50% reduction of energy use from the base case; ensuring that the hospital will continue to achieve energy reductions once in operation, and into the future. As the ConsortiumPlenary Health Care Partnerships team continues to build the new facility, the vision is beginning to be realized. Once HRH opens in the fall of 2015 it will be considered one of North America’s most energy efficient hospitals. The research developed through HRH’s and HOK’s leadership puts the new hospital on track to provide over $3,000,000 per year in operating expense savings. HRH is on target to achieve LEED gold and the predicted energy use will be 1.15GJ/square metresm_/year versus the North American average of 3GJ/m2m_/year. These efficiencies will offset 11,371 tonnes of CO2 per year; equivalent to taking either 2,187 cars off the road, saving 409,356 twenty-five year old maple trees or saving 1770 hectares (4,373 acres) of forest. In addition the site will be planted with 800 new trees to meet the City of Toronto’s Tier 1 planning specification. The Facility’s Energy Use Intensity is on target to be 103 kBTU/square foot/year; putting HRH 15 years ahead of the 2030 challenge of 101 kBTU/square foot/year.

BRAZIL’S SHOWCASE ECO-ARENA EXPECTED TO BE A CENTREPIECE OF GLOBAL ATTENTION By Greg McMillan

y the time the 2016 Olympic Games are underway in Brazil, the world will know all about a ground-breaking showcase eco-arena located in the

Green Building & Sustainable Strategies

heart of the nation’s capital, Brasília. Brazil’s national stadium, or Estadio Nacional de Brasília, will get more than its share of global attention long before 2016 – as it will be the centerpiece for soccer’s 2014 World Cup.

Designed by Castro Mello Arquitetos of San Paolo, with Ian McKee, LEED AP, serving as green building and sustainability manager for the project, the stadium is aiming for LEED Platinum designation. Work is continuing leading up to the World Cup in June 2014. SPRING 2014

“We were given the tremendous opportunity of building a stadium for the World Cup,” McKee says. “This was a moment for our firm, this was a moment for our country, to build the best stadium in the world.” With a seating capacity of 68,009, the stadium will have a number of environmentallyconscious features. Right off the top, 90 per cent of the materials from the original demolished stadium are being recycled or reused onsite. There is a rainwater harvesting and reuse system, watersaving plumbing fixtures, a two-megawatt solar photovoltaic (PV) system and LED lighting. 38

Green Building & Sustainable Strategies

Of special note: Potable water consumption will be reduced by more than 80 per cent. And a breathable façade will provide sufficient ventilation in the seating bowl and main concourses. “The large white roof protects the building and the area around the bowl and the inner bowl,” McKee explains. “The roofing reduces the heat island effect. And the solar power integrated into that roof improves overall energy efficiency.” The site will feature habitat restoration with native plantings and improvements to pedestrian access. The stadium’s location in the center of Brasília allows for bike valet parking

for 3,500 bikes inside and around the facility—unprecedented bike parking capacity for a stadium. Because more than 50% of emissions related to stadium operations are related to fan transport to and from the event, the design team felt it was critical to provide alternative, emissions-free transportation options. “When we tell people they will be able to ride their bikes right into the stadium and drop them off with a bike valet, you can see it in their eyes … that this is going to be a new stadium experience,” says McKee. The project is expected to be the first net-zero energy stadium in the world and a net SPRING 2014

energy producer. While the solar PV system is estimated to produce 2.8 million kilowatt-hours (kWh) annually, the project is only expected to use approximately two million kWh per year. As a result, the remaining energy produced will be passed on to Brasília. Outside the stadium, the design team has hoped to draw attention to an area geared to “pleasurable, healthy” experiences. More than 6,000 native plant species will be planted, ideally creating a rich and diverse park open for all to enjoy. Walkways will be permeable for water absorption into the soil and lightly colored to further reduce the heat island effect. SPRING 2014

Additionally, swales will capture and direct stormwater runoff from parking areas, cleaning the water and removing chemicals and solids. The deposits will be placed in a man-made lake for possible reuse inside the stadium. These strategies, aided by recycling and composting initiatives, will allow stadium visitors to learn about sustainable living, landscaping, engineering, as well as green design and building, McKee says. “The stadium is really designed for the local environment, fully focused on sustainability,” he adds. “And it’s an effort to have Brazil recognized as a model for the world to follow.”

Brasília’s design team is pursuing the first LEED Platinum “New Construction” certification for a major sports stadium in the world. A Platinum level certification under LEED for a regular commercial building is by itself a major challenge, but for a stadium, much less a FIFA level stadium, it is a herculean effort! • Position the stadium in an existing built environment, with ample access to public transportation, in a central location where arrival by foot and bicycle transport can be encouraged. • Dramatically improve the stadium’s overall energy efficiency, in the order of 50%-120% through quality lighting, ventilation, air conditioning and automation design, coupled with renewable energy generation integrated into the stadium’s roof, which will become the largest solar PV system in Brazil. • Reduce by more than 50% the consumption of public, potable water through strategies of water capturing for reuse, utilization of efficient water consuming fixtures (toilets, urinals and faucets) and irrigation free landscaping. • Restore habitat by adding green space where there was none before and transform parking areas into rich, diverse biospheres. • Reduce Heat Island Effect in Brasília’s city center, through increased vegetation, high SRI (Solar Reflective Index) hardscapes and a very large white roof covering the entire stadium bowl, and providing ample shade inside and outside of the facility. • Maximize natural ventilation using a 360-degree, breathable façade with open columns, which can benefit from the highly variable winds of Brasília. • Utilize recycled materials in construction and manage materials during stadium operations to reduce landfill waste. This includes high levels of recycled content in concrete and steel and using a green marketing and operations philosophy to compost materials such as plates, utensils and cups mixed with food waste in a full-cycle process that can be managed on-site. The goal is to achieve +90% landfill diversion rates during stadium construction and operation. The legacy of Brasília’s EcoArena and the CopaVerde movement, shall be a portfolio of the greenest and most sustainable stadiums on Earth, the first net-zero energy stadium in the world.
