hen aircraft designers set out to break the sound barrier, they were bent on breaking free from various forces that stunted flight and impeded further acceleration. Similarly, the South Quarter Phase IV project is resolved to break through cost barriers to building sustainable, quality affordable housing.

South Quarter Phase IV, in the culturally diverse Ventura Village of Minneapolis, Minn., is the owners’ fourth affordable housing development in a four-corner, urban revitalization project. The project, developed by non-profit partners Aeon and Hope Community, Inc., is aiming to transform the very process of developing high-performance, cost-effective affordable housing. Not only will it transform the process and outcomes of affordable housing development, it will provide a replicable model for others.

What motivates an affordable housing developer to pursue sustainability initiatives? Over the next 20 years, Aeon estimates that it and its residents will spend at least $130 million in energy and water costs, alone. That’s assuming: 1) a likely conservative, two percent inflator in utility costs, 2) adding only 100 units per year to the current 1,934 apartment homes Aeon manages, and 3) maintaining its current “green” development strategies. That’s not affordable. As a 25-year-old organization that owns, develops, and manages high-quality affordable housing, the commitment to sustainable development is already considerable. Aeon has established an internal sustainability model that drives its housing developments. The Three E’s: Environment, Economics and Social Equity are the main principles at play. Environment: The heart of green design is designing with nature as a central focus.

Economics: The economics must work financially for the project, its residents and the community. And Social Equity: As adopted by the late senator Paul Wellstone, Aeon believes “Everyone does better, when everyone does better.” With Aeon’s cumulative work in green building, it has yet to see an impact that will reach a level of considerable cost savings (both first costs and long-term operating costs). The holistic and performance-driven spirit of the Living Building Challenge™ allows it to launch to a new level of outcomes that it believes will achieve significantly better results than other sustainability programs.

Is it possible to build sustainable, affordable housing? It is inherent that affordable housing be economically viable. It is also critical to think beyond just keeping the rents affordable. Utility, transportation, health,

food and similar costs also burden residents and impact the environment. Affordable, sustainable living – as opposed to housing – must be the end goal, including a plan to minimize more than just housing costs, and not just up-front, but over the long-term. In order to do that and keep developments operating optimally over time, the issue of energy and conservation must be addressed. Up to this point, Living Building Challenge projects with net zero energy and water opportunities, have been generally smaller in scale, non-residential and non-urban – projects such as nature centers, education facilities and corporate office buildings. South Quarter Phase IV is mixed-income apartment homes with a density of approximately 65 units per acre. A typical medium density urban development is eight units per acre. South Quarter Phase IV stands out as one of the

few projects looking to use the Challenge in both urban and housing-dense environments. “One important characteristic of sustainability is density,” says Mark Shipiro of Mithun, the project’s design architect. “Higher densities are better served by sustainable solutions since residents have a variety of transportation options, live next to jobs and have easy access to amenities.” For urban densities of these levels, net zero aspirations are not easy but clearly feasible. When working on higher urban density projects, the opportunity for renewable energy income starts to hit limits depending on how dense you make the projects. Is it really possible for an affordable housing development project to perform at net zero energy and net zero water?

architects conceive the project first and then call in the engineers to make it work. The team’s first step was to conduct a series of three workshops called “The New Shade of Green,” led by Billy Weber of the University of Minnesota’s Center for Sustainable Building Research. Aeon pulled together a cross section of experts, community leaders and residents to sort through what the Challenge framework means for South Quarter Phase IV. Technical experts, local engineers, top planners, local funders, public school officials, community members, transit officials, and residents attended – even a member of the city’s storm water department was in attendance.

The first two workshops did the following: 1) engaged everyone in learning about the Living Building Challenge and 2) focused participants on the Challenge’s seven performance areas and what opportunities and barriers may be present. The group generated ideas “The Challenge benchmark isn’t an all or nothing en- to remove obstacles and take advantage of strengths deavor,” says Shipiro. “If we have reduced our water and opportunities that the Challenge provides.

sidered orientation, scale, massing, envelope, energy modeling, renewable energy potential, rainfall on site, and constructability; and how to best integrate the project within the neighborhood context. Velasco recommended that the team use Building Information Modeling (BIM) – a robust three-dimensional modeling program – to actually design the building and reduce costs through better system integration and fewer costly change orders in the field. Energy modeling alternatives, conducted by The Weidt Group, proved critical for informed decision-making on the project’s efficiency. Excel Energy, a local utility company, put together energy schematics to help the team balance renewable energy options. The team worked through six possible massing schemes and went back to its workshop participants with one optimum scheme for feedback. What discoveries, so far, did the process uncover that has led the team to choose the particular design? It is

one that realizes cost-savings breakthroughs, not only over the long-term, but in construction costs. Additionally, all players in affordable housing – including design teams, residents, and funders – need to embrace a paradigm shift in how to achieve, quantify and capitalize cost savings.

The business of green in building sustainable affordable housing The team’s commitment to seeing cost breakthroughs has never meant that it is aiming to build cheaper than conventional buildings. It really means the team is looking for the “sweet spot” between the various components that make up the fabric of the building. For example, the team set a building energy output goal of 15 kBtu/sf-yr (compared to the energy output of typical code building measuring 100kBtu/sf-yr). Based on achieving that goal, the team designed and evaluated alternatives. The team discovered that us-

The development of South Quarter Phase IV is being watched by many in the housing development arena because of its goal to provide a practical, replicable and scalable model for developing sustainable affordable housing.

Building and operating sustainable affordable housing also necessitates changing the way residents think about daily living. Aeon and Hope Community are conducting a sustainable living, resident engagement pilot program at The Wellstone – a 49-unit, four-story (75 percent affordable) apartment building. The goal is to foster long-term changes in residents’ behavior around decreasing water and energy consumption and increasing recycling by providing education and encouraging resident leadership. Based on findings of the pilot, a program will be adapted to benefit residents of current and future properties.

or space. Building a high performance building means that 1) everybody’s money is better spent, 2) government programs that support affordable housing, Aeon and its funders see more money going to people and less to fossil fuels, and 3) the residents are less vulnerable to spikes in energy costs. Everybody wins.”

Pioneering the aspiration of sustainable, affordable living for multi-family housing is no small endeavor. When Aeon and Hope Community break ground on South Quarter Phase IV sometime in the next two years, they will have broken through cost barriers that impede creating sustainable solutions to affordable housing development. On the wings of the Living Building Challenge™, sustainable affordable housing development will become tangibly more cost-effective and provide living futures for residents and communities.

Van der Ryn When I learned that the incomparable Sim Van der Ryn had accepted my invitation to be interviewed in Trim Tab, my excitement for the opportunity was only equaled by my expectations of the exchange. After all, this is a person that “got it� (the fragile state of the planet at our hand, our inseparable role as part of the grand ecology and the nature/design connection) more than forty years ago and has been actively influencing change throughout his entire career. From where I stand, Sim embodies the vision and wisdom that pioneered the green building movement and is every bit as relevant today.

the unused land into a “People’s Park”. Within a few weeks, hundreds of volunteers, including children, and families were busy leveling, digging, planting, designing, revising. Sometimes the frenetic work would stop and the assembled group would have an on-the-spot community design meeting. “We’re digging a pond”. “That’s a bad idea. Children might drown.” More discussion followed, “OK let’s fill it back in”. And so it went, a true participative design and construction process: spontaneous, chaotic, high energy, as a park emerged. I was teaching a graduate class in Design Methods and documenting the process of designing and creating People’s Park became our semester research project. The Campus authorities, goaded by Governor Ronald Reagan, were told to take action against “anarchists” and “communists”. I got the College of Environmental Design to agree to take over the project as a Field Station, an idea rejected by the Administration. A few days later, I had a call from the Chancellor. “You need to meet with the leaders of Park Project and tell them they have to leave”. I replied, “You don’t understand, there are no leaders. Why don’t you go to the Park and see what’s going on. It’s exciting”. He replied, “I’m too busy” and I asked, “When are you going to show some leadership?” and he replied, “I’m just a janitor for the Regents and the Governor.

“If all you have is a hammer, everything looks like a nail” —anonymous

“Measure twice, cut once” —old carpenter saying

trim tab

The green building universe has become awash with assorted tools. There are countless green certification programs, energy, daylight and natural ventilation modeling programs, green product labels and Life Cycle Assessment tools to name a few. The list has been growing longer in recent years as our relatively young movement struggles to figure out how to deliver on the promises we have made. But how do we actually reduce the environmental footprint of our buildings and other designs? How do we select the right materials and make the most informed choices for our projects? And how do we reassure our clients (and ourselves) that we are “on-track” to meet project goals while the project is still in design?

I m a g e © [g u]

his article speaks to matters that, like everything in Trim Tab, have important consequences. The tools we use to solve problems of any kind are critical in determining successful outcomes. Carpenters require quality tools to produce high quality craft, and a surgeon’s tool requirements are even more rigorous for achieving safe and effective medical outcomes. Individuals in the building professions who focus on reducing the environmental footprint associated with our work rely on a series of tools to help make informed decisions relative to energy and resource use and a host of other factors. However, just as a the wrong screwdriver will inevitably strip a screw, the wrong tools or even the right ones, wrongly applied, will result in negative outcomes.

Why, we use tools of course!

29


Everyone wants a magic tool to apply to particular situations to help us make the best possible choices. We especially like things that can seemingly make complex and multi-faceted issues both simple and definitive. We love getting charts, graphs and exact percentage answers that allow us to show how clever we are and how good and precise our decisions are. Part of our love for tools comes from the desire for the simple fix – we seek clear answers, not nuances. “Tell us what it will cost, tell us how much energy it will use.” “Tell us how many LEED® points we’ll get.” People demand answers– and our industry, often against its better judgment, tries to deliver. “Here you go,” we say… “We’ve done our analysis and this is the answer.” We distill down and segregate issues and provide our clients with what they want. And what many people want is the one-liner, the certificate or the plaque. We want tools, titles, ratings or labels to tell us when we have been “good enough,” that our choices are responsible “enough.” We want fancy bar charts to validate our decisions. We share a culture that desires certainty in a highly uncertain field and we seek the air of scientific certainty even for things that are, by their nature, impossible to quantify.

in our industry than people would like to admit. Whatever the case, it is clear that determining when and how to utilize various tools is the key - and having the good sense to avoid them or to use a different protocol or system is essential. What is also essential is understanding that our tools are not the point or end. Just like process is not the point or end. They are a means only – and they should not be treated as an end. Tools, no matter how powerful, should be respected but never revered or fully trusted.

I want to be perfectly clear. We do need tools. They are vital to furthering the performance of our buildings and the quality of our infrastructure. I have spent a great deal of my own professional career utilizing many of the tools used in the green building world as well as time creating the tools that our industry needs to move further, faster. Working with Bob Berkebile and my old team at BNIM, I provided a great deal of feedback to the first iterations of LEED and served on voluntary committees to improve standards. I have witnessed LEED used as an incredible force of change in the industry (see my defending LEED article, in the Spring 2011 Issue of Trim Tab) and also greatly misapWe are, culturally speaking, addicted to pushing a but- plied as people chase the cheap and easy points and ton and getting an answer from some authority… any seek shallow marketing benefits. authority at times.

als more expert than I in each of the areas where tools are used in green building- but to provide context. I have seen the best and worst in the industry. And that is what this article is about in the end. I offer the following general points on tools:

Many well meaning and highly intelligent people misuse tools and the results become counterproductive and even damaging, sometimes leading people to exactly the opposite solution than what should rightly be realized. Yet, the right tool in the right hand can be a beautiful thing and we can learn a great deal from those individuals who truly understand how to use the right tools to make informed decisions. So, to this end, let us examine several tools.

and yet another thing entirely to try and come up with a single number to represent “impacts to human health” or “habitat impacts.” Using a reductionist process to get a single answer for something as holistic as health or ecosystem is abusing the tool’s capabilities. Shame on people who push answers that are not answers. Certainly links can be made – and certain pollution categories have known, measurable impacts to things like habitat and health – but do not present results as if they neatly translate into a holistic framing of those issues. Geeking Out

Simply put, work with LCA experts who have a healthy degree of skepticism for their own tools and who are upfront about their limitations and what they can and cannot do. Avoid experts who are enamored with LCA as if it is a religion. They are out there so best to run like mad and lock your doors.

powerful new tool in the designer’s toolkit – and one that can extend to engineers and contractors and affect the whole process of design and construction. At this point, I highlight just a few conclusions and issues: Experience is essential

I am repeating myself here, but you have to know how to put a building together – for real in the field. A model that looks highly convincing is not the same as contract documents that really work. The majority of the buildings we admire most in the world were done before BIM or computers even existed. That reality is important to keep in mind. BIM adds powerful functionality to our decision-making and design process but it is not the only arrow in the quiver. Using multiple paradigms

Moving toward the climate tipping point This is the first in a series of three Trim Tab articles that assess the tools available now for reducing North American greenhouse gas emissions. This first article summarizes the current science. A second article will analyze US industrial emissions. I will argue that it is possible to cut emissions dramatically, and without delay. The third presents a set of practical proposals that will help us achieve this goal. Some of these proposals are for new green technologies, others are for stronger anti-pollution regulations, and others are for lifestyle changes that will (directly and indirectly) cut fuel use. The fourth article will lay out exactly how these proposals will work. The general conclusion: we can cut emissions by 40% to 60% of our current levels by 2050 if we have the courage to make these changes.

However, there will still be very hard times ahead. According to the latest climate models and the very discouraging observations coming out of the arctic, it is too late now to avert catastrophic global warming. We are going to have to adapt to a hot, dry and hungry planet. The principal message I hope to convey is this: buildings and neighborhoods must be reengineered to capture their waste and to support a local food supply. We have to radically redesign our settlements to adapt to the hot, dry and hungry world that awaits us. A roadmap for change will be the subject of my upcoming book to be published by Ecotone.

Another grim picture comes from the Canadian artic. Last summer Inuit children near Inuvik discovered a new game: throwing matches onto newly-formed meltwater ponds in the tundra2 . Methane gas (which is lighter than water) gurgles up from the rotting permafrost below ground and floats on the surface of these ponds. The gas bursts into flame when the children toss their matches.

These are signs of things to come. The arctic is warming faster than predicted by even the most pessimistic computer climate models.

Opportunity Outside of Shadow A new paradigm for city planning

INTRODUCTION Imagine your team just completed your firm’s first Living Building! This is an incredible accomplishment and a milestone in building performance. Then, just as the project enters it’s second year of life, the building ceases to perform as intended due to an adjacent property. A new project emerges to the south of your building and now shadows your project for a portion of the year. It’s not a large portion of the year, but it’s enough to erase the net zero performance of your efforts and interfere with your investment. The new project meets all applicable regulations and even though you are financially burdened there is no recourse. This mater would be easily resolved If only all buildings had a collective moral obligation beyond current statutes, allowing solar access to neighbors as a collective right. Its too bad all projects aren’t living buildings as the Living Building Challenge does indeed insist on this standard.

46

Imperative 18 of the Living Building Challenge sets a limit of shadow height on neighboring buildings based on the surrounding density (or transect). Transect L5, for instance allows 15 meters, which is about a 49’ high shadow. Transect

That a “project may not block access to, nor diminish the quality of, fresh air, sunlight and natural waterways for any member of society or adjacent developments”.


Broad solar access substantially benefits the entire community in many ways. • results in energy security / savings • reduces operating costs • acknowledges finite resources • helps to curb climate change • provides comfort, aesthetics, and contextual responses • supports community based thinking, moralistic aspect of social justice through the “right to light” concept

is a maximum 3D volume a building could occupy and still allow solar access to neighboring facades. Think of SOLAR ENVELOPES as the “Upstream” version, and SOLAR ACCESS as the “Downstream” version of solar flow from the sun. For example, the City of San Jose precisely describes what constitutes a solar access dwelling unit. The amount of shade on the dwelling unit defines its level of solar access. Shading from a structure and/or vegetation must not exceed specific amounts to comply with the community requirements.10

PRECEDENT AND HISTORICAL CONTEXT

Other countries also have laws in place, some that build on historic efforts based on the fundamental premise that natural sunlight was a privilege common to all landowners. In the United Kingdom, the Prescription Act was passed in 1832, noting “When the access and use of light to and for (any building) shall have been actually enjoyed therewith for the

There are 36 states (and multiple other municipalities) that limit building envelopes from shading neighboring structures. Some are required by civil law, and others are more explicit within zoning regulations.1 These zoning regulations sometimes refer to “Solar Envelopes”, which

full period of 20 years without interruption, the right thereto shall be deemed absolute and indefeasible…”  2 This was reiterated in 1865 by the “Right to Light” easement, giving a an owner of a building the right to prohibit neighboring construction if the owner has enjoyed access to direct daylight for 20 years or more. Debates continue over methodologies to enforce it, but the history is deep rooted toward this concept.7 In the Dutch building codes, the principal façade of houses must receive 3 hours of direct sunlight between the dates of March 21st and September 21st, the vernal point and autumnal points of the equinox, when the solar elevation is about 38°. For East and West oriented houses, the solar elevation is lowered to 32°, which reflects the sun’s path across the sky.8

hardly any building attempted to use solar in urban settings and not enough daylight? Simply turn on your florescent lights was the common theme! But times are quickly changing, and access to the sun is quickly meaning much more. For instance, the need for energy security, the protection of investment in decentralized energy infrastructure and soon property values will increase that are tied to energy efficiency. In a peak oil world the sun is more important than ever.

Most blatant, allowing solar access to our neighbors through the use of solar envelopes is paramount because of energy security, climate change, community based thinking, comfort, aesthetics and other contextual responses. Any forward thinking city should begin to invest in rules and regulations that ensure future resilience and protect the responsible investment in decentralized renewable energy.

HISTORIC SOLAR RIGHTS LAWS

1832 Prescription Act provided England, “When the access and use of light to and for (any building) shall have been actually enjoyed therewith for the full period of 20 years without interruption, the right thereto shall be deemed absolute and indefeasible, any local usage or custom to the contrary notwithstanding, unless it shall appear that the same was enjoyed by some consent or agreement, expressly made or given for that purpose by deed or writing. . . “ 2 1865 “Right to Light” is an easement from English Law giving a an owner of a building the right to prohibit construction if the owner has enjoyed access to direct daylight for 20 years or more. Methodologies were developed further in 1865 by Robert Kerr RIBA. 50/50 rules, Daylight Factor rules, tables, and other rules of thumb were created. We are fairly certain they didn’t have Sketch Up which makes this analysis and iterative studies a bit easier. 3 1932 In the center of London, near Chinatown and Covent Garden (particularly in back alleyways) signs stating “Ancient Lights” can be seen marking individual windows. The design and construction of Broadcasting House was affected by locals declaring their right to ancient lights. It resulted in a unique asymmetrical

sloped design that allowed for sunlight to pass over the building to the residential quarters eastward.4 1862 Bushnell v. Proprietors of Ore Bed – Court rulings decided it was not worth the restrictions placed on new projects. In this case solar access laws were integrated, only to be weakened by the supreme court and other cases around 1875 and 1896. 12 1959 Fontainebleau Hotel Corp vs. Forty-Five TwentyFive, Inc. – Florida Appellate Court stated “ancient lights” doctrine has been unanimously repudiated in the United States. 5 2006 “Right to Light” has been the basis for legal action as recently as 2006, Regan vs. Paul Properties. Others have followed.6

Early efforts to protect solar access took the view that every landowner’s right to natural sunlight deserved protection. It was later realized that broad solar access substantially benefited the entire community in many ways. However we have forgotten some of these balance points to a middle-ground between maximizing FAR and allowing others to have their rights.

Testing What It Takes To Respect Solar Rights

As a way to visualize the impacts of the Living Building Challenge requirements, a hypothetical city was created with various street widths, maximum street grade, natural features and public space. (See Figure 1) The goal was to investigate what affects these variables had on the overall height, volume and Floor Area Ratio (F.A.R.), and to build on the fundamental theories established by Ralph L. Knowles13: 1. Diagonal streets are better than a cardinal orientation.

On winter solstice, it was assumed that there would be a higher priority for sunlight passage into buildings than outdoors spaces. Thus, public spaces would have direct sun for most of the year, but not as much during the winter solstice.

TEN DESIGN PRINCIPLES FOR SOLAR ENVELOPES Using the metrics in the Living Building Challenge as a guide, five different solar envelope studies within the hypothetical city were completed. The results inspired the following design principles: 1. Buildings can still have generous heights if properly located within the city. Current Living Building Challenge requirements yield densities beyond the average base FAR allowed, and roughly double the actual FAR for a mid-sized city such as Portland, Oregon. This was tested with grade variation, street width variation, and other realities of urban design. 2. Using solar envelopes creates homologous instead of monotonous building massing opportunities. They come from the same source, but are not repetitive. The resulting buildings range from 4 to 30 stories high. Variance between buildings would be even more true in the hands of qualified designers, as the massings represented below were created by an unqualified designer. 3. Creating solar envelopes (as a design process stepping stone) is about “sculpting light” instead of “sculpting buildings”.

ever, buildings do not necessarily have to conform to the urban grid, but maximizing profits pushes the design toward this goal. 8. Solar envelope volumes are heightened as street widths increase. This is blatant, but how much? Going from a 60’ right of way to a 98’ right of way yields about 1-3 more floors in a building. 9. The further from the equator, the less of a difference street width makes. Conversely, the further from the equator, the less allowable height available for given specific solar access rules.

As a point of reference, Portland, Oregon has an average base allowable FAR of about 6 within the city center. The same area has an actual FAR of 2.5 (existing buildings). Almost all of this area would fall into Transect L6 according to Living Building Challenge rules. The studies that follow are based on L5. Even with this lower shadow height restriction assumed, the studies showed FAR allowed within the solar envelopes allowed by The Living Building Challenge exceed current allowable FAR in the heart of Portland. In other words, the current rules within The Living Building Challenge work for L5, let alone L6 requirements when compared against what’s allowed by this given city. To illustrate these “Recent Principles”, we can study the latest solar envelope research performed. A hypothetical city was created with various street widths, maximum street grade, natural features, and of course, public space (see figure 2). The goal was to investigate what affects these variables had on the overall height, volume, and FAR possible WITHIN The Living Building Challenge current rules. Each street number had a different width; the higher the number, the wider the street. All grades are sloping up at 10% as designat-

rules. They are not meant to be the end forms of the buildings. Rather, they are the resulting bounding volumes that compliant buildings could occupy at a maximum. Note how the public spaces affect the maximum heights. The East-West running park has the most dynamic affect. The river running mainly North-South also has a large impact. Massings fitting within these maximum volumes grow toward the sun, thus becoming more biophilic. What about shading outdoor spaces? It is assumed that allowing light to buildings is a higher priority than allowing light to outdoors spaces during the winter solstice. Thus, public spaces would have direct sun for most of the year, but not as much during the winter solstice.

of 55 degrees, thus focusing on that range of latitudes for a world-wide goal would be pertinent. 2. An exception in hot climates where shade is coveted. 3. An exception if energy needs are supplied by the project to adjacent shaded buildings. 4. Measuring solar access via areas / SAR instead of total height. What if we considered the concept of FAR applied to Solar Access Rations (SAR)? What if restrictions could be relaxed by, say 25% on a given block, if other parts were increasing solar access by 25% from the maximum height allowed? SUMMARY

So what? What does this mean to my project? What it means is there is an opportunity (Living Building project or not) to consider the conditions that lay beyond the property lines.

Creating a Green Dividend Overcoming the (presumed) cost of sustainable construction

henever you’re facing a barrier that’s actually been given its own name, you have to know you’re up against a resilient roadblock. Such is the case with “the green premium” – the presumed cost of constructing buildings that are environmentally responsible. As soon as you hear those words, you can be sure that the next question in everyone’s mind is not whether green buildings cost more; it’s how much more?

Our development, UniverCity, is unique, but we work continuously to make sure that the best of what we do here can be replicated – easily and affordably – elsewhere. That’s not fair. Certainly, it is not accurate. In creating the UniverCity development on Burnaby Mountain in Metro Vancouver, we at the Simon Fraser University (SFU) Community Trust have proved time and again that you can raise the bar on environmental performance and stay competitive with “browner” buildings. We are on the verge of demonstrating that you can build a Living Building™ for less than the cost of a conventional alternative. It’s not necessarily easy. There is a learning curve (and those can always be expensive). There is resistance to be overcome. But the “premium” that we all should be worrying about is the long-term cost of ignoring the value (and values) inherent in green design.

adjacent to Simon Fraser University, by wide agreement the best comprehensive university in Canada. SFU was built in the mid-‘60s, and its far-sighted designers – the architects Arthur Erickson and Geoffrey Massey – included plans for a neighboring suburb, the profits from which could help underwrite the costs of running the university. Three decades passed before any work began on SFU’s “endowment lands,” and by then, the idea of a fourhomes-to-an-acre suburban tract had lost its appeal. Instead, then-SFU President John Stubbs called for “a model sustainable community.” The SFU Community Trust was formed in 1997 to make that vision a reality – and in the process, has transferred between $155 million and $170 million (today’s dollars) in development proceeds to the university for teaching and research.

We consulted developers beforehand, to ensure that our standards were flexible and achievable, but the best have actually said that they appreciate the requirements being set in law. “It’s nice to have a level playing field,” says Kerry Kukucha, Development Director for Porte Developments. Porte was the first to develop a building under the new bylaw – and buyers snapped up the 75 units in its Origin pre-sales so quickly that Porte then bid on a new UniverCity parcel, on which it plans a 48-home development called Lift. This new building also hit the higher energy-efficiency target, thereby giving Porte the density bonus.

Three examples include: Verdant, a residential building developed by VanCity Enterprises and specifically designed – in both its financing and its construction – to be affordable for SFU faculty and staff; the Hub, a mixed-use project on the High Street; and the University Highlands Elementary School, which will be the first LEED Gold retrofit school in Canada, as well as a BC Hydro solar demonstration project.

60-unit structure that is one of the most energy-efficient woodframe buildings in Canada. Verdant has a geo-exchange heating system, as well as a passive solar hot water system, both of which were financed through a separate mortgage. Residents now pay the equivalent cost of energy for a traditional building, and use the operational savings to pay down the mortgage. When the mortgage is retired, residents’ costs will drop – probably while everyone else’s energy costs are skyrocketing. Our second solution is a Neighborhood Energy Utility, a hydronic system that ultimately will provide heat and domestic hot water from a central biomass facility, fueled with construction wood waste that would otherwise be landfilled. This system, which will begin operation early in 2012 with a temporary high-efficiency, natural gas boiler, will remove the need for furnaces and hot water heaters in every residential unit in the third and fourth phases of our development, helping developers meet their energy-efficiency requirements. The biomass facility is also expected to replace the aging gas incinerator that currently serves the university’s institutional buildings, reducing related greenhouse gas emissions by more than 70%. The truest test for all this innovation is whether the market can “afford” it, and by that measure, UniverCity is passing with high marks. Developers such as Porte are successfully pre-selling whole buildings

before beginning construction. And far from finding the sustainability standards a burden, Porte’s sales manager, Kristie Marsden, says that buyers quickly identify them as a primary selling feature. “I get two kinds of buyers,” Marsden says, “Some people are on a mission: they’re only going to purchase a home built to the highest green standard. Others are looking here because they like the community, and they’re pleasantly surprised.” Once they see they can have energy efficient homes that were built to high environmental standards, they don’t want to accept anything less. When it comes to assessing the “cost” of a building, that’s the last word: no matter how much money they “save” in construction, if a developer can’t sell a project, it was not “affordable.” We’re proud, at UniverCity, to be building a community that people want – one that will be enduring and, especially, one that has a light environmental footprint. The long-term savings from that approach will benefit everyone, whether they helped pay for it or not. Dale Mikkelsen is Director of Development at SFU Community Trust.

The Building Materials Challenge: The Selection Process VanDusen Botanical Garden Visitor Centre + Centre for Interactive Research on Sustainability at the University of British Columbia

trim tab

At the Centre for Interactive Research Sustainability the naturally lit laboratories and offices surround a courtyard with a daylit auditorium. The solar aquatic wastewater treatment system is prominently located behind the corner glazing on the ground floor.

Perkins+Will has recently completed two projects in Vancouver, British Columbia that are targeting Living Building Challenge™ certification. Both the Centre for Interactive Research on Sustainability at the University of British Columbia (UBC) and the VanDusen Botanical Garden Visitor Centre opened to the public in the Fall of 2011. The projects are based on a holistic approach to sustainability, closely aligned with The Living Building Challenge (the Challenge). Both of the buildings are integrated into the environment beyond their site boundaries and will have a positive overall effect on their surroundings, a key concept envisioned by the Challenge. Selecting the most appropriate and sustainable materials for each building is complex; there are many parameters to consider in terms of design intent and the life cycle environmental assessment of building products. Choosing to pursue the Challenge has provided a framework of specific targets for materials.

cus of this discussion is on three specific Imperatives within the Materials Petal which directly affect materials selection: Red List, Appropriate Sourcing and Responsible Industry. These three Imperatives have provided design teams with ambitious targets in addition to project goals related to the use of materials. Red List The most difficult Living Building Challenge Materials Imperative to successfully achieve is the avoidance of items on the Red List, a list of substances that cannot be used in projects because they have been determined to be detrimental to human health and the environment. The intent of the Imperative is to avoid the use of any material that contains within it a Red Listed substance and applies to products throughout the building, including electrical and mechanical components. There are some temporary exceptions to the list granted by The

International Living Future Institute to acknowledge that compliant products are not always available. Despite these exceptions, it remains extremely difficult to find the products required in complex buildings types that meet the terms of the Red List Imperative. Perkins + Will found that of all the items on the Red List, Poly Vinyl Chloride (PVC) is one of the most prevalent. A constituent of PVC, Vinyl Chloride, has been classified as a carcinogen by the EPA (United States Environmental Protection Agency) and IRAC (International Agency for Research on Cancer). PVC is typically present in many architectural, mechanical and electrical products. A resourceful and interesting solution at VanDusen was implemented to replace standard PVC foundation drain tile. ABS (Acrylonitrile Butadiene Styrene) plastic pipe was substituted and drilled on site to create drainage holes. The local building inspector required that a particular pattern of

72

Winter 2012

holes specified by Canadian standards be drilled into the ABS before permitting its use. Appropriate Sourcing Another challenging Living Building Challenge requirement is that all materials must be appropriately sourced according to a logical sourcing radius relating to the weight of the product, its potential to contribute to the ongoing performance of the project, and opportunities to reinforce place-based solutions. For example concrete, a heavy material, has to be manufactured and extracted within 500km of the project, whereas ceiling tiles, a lighter product, can be manufactured and extracted from a radius of up to 2000km. The appropriate sourcing requirement is harder to meet in Vancouver than in many places on the continent because the manufacturing base, the source of a great many typical building products, is

on the east coast. Vancouver’s location on the Pacific coast is remote from the industrial heartland of North America and the sourcing radii stretch over the Pacific Ocean, making it much harder to meet the sourcing requirements. For example sheet flooring is required to be sourced within 2000 km of the building, but no products could be found that were both manufactured and sourced within this radius. Responsible Industry In addition to the Red List and Appropriate Sourcing requirements, the Challenge’s Responsible Industry Imperative requires that projects advocate for third party certified standards for sustainable resource extraction and social justice. Presently requirements for this Imperative are that all wood products be certified to Forest Stewardship Council (FSC) 100% labelling standards, from salvaged sources or

from the intentional harvest of timber onsite. FSC is a worldwide organization that provides a certification system for sustainable harvesting of wood in each location which includes logging restrictions and fairness for workers. FSC-certified wood in Canada is mostly produced in the east; so much of the projects’ new wood actually comes from FSC sources in the western United States. Salvaged wood is available for purchase, but the market is limited and often requires that the wood be sourced ahead of time. The older salvaged wood is in demand as it is often of better quality than more recently harvested wood and has a desirable patina. Materials Requirements Adding to the complexity of sourcing, the Living Building Challenge requires that specified products comply with all Imperatives. For example, a wood beam

73


nic lehoux

must: not contain added formaldehyde (Red List), be sourced within 1000km (Appropriate Sourcing) and be either FSC-certified or salvaged (Responsible Industry). Often after research, a product could not be sourced that complies with all the requirements. The Challenge allows for exceptions for the limiting factors between Imperatives in these cases, particularly allowing for an increased sourcing radius to include products without Red-Listed substances or FSC-certified wood products.

Industry Imperative have been used in different applications throughout the project.

The FSC-certified prefabricated roof panels, composed of glue laminated beams, framing lumber and plywood were built in a local FSC-certified shop. Each of the 60 panels have a unique three dimensionally curved shape, some as large as 60 feet long and 10 feet wide. The panels were designed by the architect using Rhino and Revit software and the 3D model was then used by the fabricator to build the panel geometry and incorporate services into the curved Use of Wood panels.

Salvaged wood and timber from the site were incorporated into landscape elements and millwork. Lumber salvaged from a demolished breezeway on the site was resawn and used to construct several new bridges and benches in the landscape. The wood doors and millwork were salvaged from an office building in Seattle. This salvaged wood forms the finished visible surface of the millwork and has a weathered patina that fits the architectural design intent. The number of trees that had to be cut down on the site were minimal; the timber that did become available was seasoned and used to construct exterior benches. The building was located in a section of the gardens in which very few trees were growing and, in fact, invasive species were present that were identified and removed. Rammed Earth

In addition, the curved concrete walls throughout the project were not covered by additional finishes. The concrete walls were not cast in the usual way, but sprayed onto curved forms using shotcrete and then trowelled on the most visible side. This construction method gave the concrete walls a beautiful, organic look which did not need to be covered by additional finishes. Watch Lists The elimination of materials that can be detrimental to human health in buildings is a universal concern; the Living Building Challenge Red List is one of a number of excellent lists that have been compiled by different organizations in an attempt to eliminate toxic materials in our buildings. Perkins+Will Architects has developed its own Precautionary List of substances commonly found in the built environment that have been classified by regulatory entities as being harmful to the health of humans or the environment. This tool is intended to promote transparency and be a resource for project teams. The Precautionary List (and suggested alternatives) is available to the public online at www. transparency.perkinswill.com.

Rammed earth walls were chosen not only to complement the curvilinear design but also because their ingredients are locally available and free of Red List items. The rammed earth walls are double wythe construction with insulation sandwiched between the interior and exterior layers. The rammed earth mixture, which resembles a dry concrete mix, was pneumatically tamped in layers inside heavy duty formwork. The organic layers were part of the design intent, but the lack of transparency in the disclosure of proprietary ingredients made the structural design of the walls and tracking of materials challenging.

Reinventing Fire By Amory Lovins

Chelsea Green Publishing, October 2011

Imagine waking up in your super comfortable and healthy home and deciding what form of transportation you will take to work today – personal electric vehicle, bicycle share, highly predictable mass transit, or telecommute on the information super highway. Your home and office are comfortable and quiet because they are designed to take advantage of natural systems. They are smartly sited, extremely well insulated and ventilated with plenty of fresh air. Your workforce is more productive and absenteeism is largely a problem of the past. Your home and office building have become energy harvesters and storage receptors. Rather than paying for electricity to heat and cool your home, you now get a monthly check from your utility company for the excess power you generate and sell back to the community. The news headlines are no longer dominated by stories of war and unrest in the Middle East in part because the United States no longer fuels the feud in order to protect the precious oil reserves once thought critical to maintaining the American way of life and indeed world prosperity.

Not only that, but Lovins delivers a convincing argument that such transition will unleash enormous economic potential for a broad and diverse set of stakeholders and participants.

“It is no small task to eloquently articulate a better energy future and a method of achievement while thoroughly examining the real barriers to implementation. Reinventing Fire does exactly that in an easily digestible form told with a voice of hope and inspiration. ”

Reinventing Fire, Lovins and the Rocky Mountain Institute examine how to eradicate dependence on fossil fuels, in large part by drastically reducing energy waste, in an effort to curb environmental degradation, social unrest, and economic uncertainty.

At the end of this book, Lovins implores “Shall we continue down the path we’re on, toward economic stagnation, rising costs, unpleasant risks, social upheaval, and an ever more dangerous world, or shall we make a bold break and start laying the energy foundations of a world without waste, want, or war?” Reinventing Fire Reinventing Fire examines the four dominate sectors entices readers with promises of vast economic opporof the economy that consume fossil fuels – transpor- tunity, social benefit and environmental healthy while tation, buildings, industry, and electricity generation. exposing a plethora of current tools to achieve the enEach sector is broadly described including its current visioned new energy future.

CHARRETTE FACILITATION

DESIGN DEVELOPMENT GUIDANCE

Measure Twice, Cut Once.

WHAT IS IT? Customized training is available as an optional service for organizations and project teams to ensure that everyone has a shared fundamental understanding of the Living Building Challenge or particular Petal area. HOW DOES IT WORK? Whether there is a specific area of interest or a desire for a private presentation of an established curriculum, the Institute can bring the education to you. The most common workshop requested is a full-day introduction to Living Building Challenge that also includes discussion of contextual information such as development patterns and density, and regulatory, financial, behavioral and technological barriers and incentives.

WHAT IS IT? To steer teams toward innovative yet feasible solutions for their Living Building Challenge projects, the Institute offers an optional service to lead the kick-off meeting or “charrette” and help define fundamental, strategic goals. HOW DOES IT WORK? The charrette should take place at the beginning of a project when the potential to explore is at its fullest. The one-day meeting format focuses on fostering an interactive dialogue that allows participants to consider each area of impact. The two- or three-day format allows time for a deeper examination of promising ideas. The Institute designs the agenda, facilitates the session, and provides a follow-up summary.

WHAT IS IT? This optional service is intended to improve a project’s potential to comply with the Living Building Challenge requirements at a point in the design process where adjustments are still possible. HOW DOES IT WORK? The Institute spends a day with the team to learn how the project accounts for each Imperative of the Living Building Challenge (an option for a virtual meeting is also available). Following a review of the project documents, we will issue a report outlining our guidance for the team to improve their ability to succeed. It is possible to receive feedback on the Imperatives within a single Petal, select Petals, or all seven Petals of the Living Building Challenge.

HOW DO I GET STARTED? For more information on fees and scheduling, email: certification@livingbuildingchallenge.org

Living Building ChallengeSM is a philosophy, advocacy tool, and certification program that addresses development at all scales. It is comprised of seven performance areas: Site, Water, Energy, Health, Materials, Equity, and Beauty. At the International Living Future Institute, we believe that a compelling vision is a fundamental retirement of reconciling humanity’s relationship with the natural world.

Shining a Light in the Philippines

Many people living in the slums of Manila, Philippines do not have access to electricity and live in relative darkness. Until some inventive and creative thinking citizen discovered that an old plastic soda bottle, water and the sun will shine much needed light on this dark situation. The recycled plastic bottles are filled with water and wedged in a hole cut in the roof, with the help of the tropical sun the makeshift bulbs generate 55 watts of light – with no electricity involved.

Life in the Slow Lane: One less parking space, one

There are now more than two-dozen parking spaces that have been turned into pedestrian nooks in the year of 2011 in San Francisco. San Francisco’s “Pavement to Parks” project is seeking to temporarily reclaim these unused swathes and quickly and inexpensively turn them into new public plazas and parks. This project has been inspired by similar projects in New York City where plazas and seating areas have been designed and built into excess roadway by treating the asphalt, installing movable tables and chairs and placing protective barriers along the periphery.
