Carbon-positive cities, biophilia, and data-centric decisions define the next American city that architects can help create
In discussing solar orchards, biophilic cities, and illustrative mapping of everything from water surges to public protests, architects at the 2016 SXSW Eco conference brought the audience a dynamic voice for change. In its fourth year, the sister conference to the larger South by Southwest festival has grown into a three-day convergence of all things driving global change under the umbrella of design, technology, and business. Its basic premise is a forum for ideation and connection across industries. Participants arrive from around the globe, united by aspirations to establish new ways of dealing with health, food, water, climate change, clean air, energy, and development.
“Architects provide a fundamental voice in this conference,” notes SXSW executive producer Morgan Catalina. “We are talking about environmental and social change. It is a realm that architects can shape, change, and influence through design.” In fact, design thinking and problem-solving were a priority in much of the conference discussions. Topics ranged from idea-driven calls to action to explanations of developing software tools. Creative solutions involving cross- and multi-disciplinary teams were billed as the most effective ways to address many of the world’s pressing problems.
Time for a (sustainability) revolution
In his keynote, William McDonough, FAIA, of William McDonough + Partners, called for a revolution as he emphasized the need for carbon-positive cities and work toward climate change reversal. A visionary for more than 40 years, McDonough has been a pioneer in sustainability. He co-created the Cradle to Cradle philosophy, and all his work promotes a complete understanding of material health in the design process coupled with built-in renewable energy and social fairness.
He is currently working on concepts for a Chinese city that can feed and power itself. In Mongolia, McDonough’s “solar orchards” allow industry and agriculture to live in the same place. Solar collectors are elevated six feet, allowing for grazing animals to occupy the same land. “This is beautiful … grasses come back by themselves,” stressed McDonough. His is a call for a new language to deal with carbon that promotes constant improvement and a reevaluation of the current framework from which architects and designers evaluate their impacts on the environment and the future of human health.
Connections to nature
Likewise, Amanda Sturgeon, FAIA, chief executive officer of the International Living Future Institute, noted that architects should change the way they are designing, and recognize that “people are a part of nature, not separate from it.” As part of the workshop on biophilic cities, she presented her research related to biophilic design emphasizing the reconnection of humans and the natural world. Biophilic cities prioritize the integration of green and blue ways throughout urban zones, urban farming initiatives to support food deserts, and integration of wildlife preservation in planning efforts, among others.
“We are talking about environmental and social change. It is a realm that architects can shape, change, and influence through design.” - SXSW executive producer Morgan Catalina
Sturgeon summarized her argument for new design thinking: “Most of architecture is being created with no connection to place, climate, geography, or regional context. With increasing urbanization, and the fact that we spend 90 percent of our time inside, our fundamental connection with nature is disappearing. At the same time, the Paris climate agreement requires that buildings radically reduce their energy use, past the incremental efficiencies that we have been achieving. If we don’t design our buildings to adapt to our climate, we will not get there. I believe this is an urgent issue for the creation of our buildings. Architects must change the way that they design, and we must train our young architects to have the skills and abilities to design in this way.”
Tools to further the profession
Going beyond just understanding a building’s site was part of the inspiration for Perkins+Will associate principal Leigh Christy to develop Hazel, a software tool for optimizing planning for stormwater infiltration, collection, and reuse. Christy sees part of her role as an architect is to engage in larger questions about the future of the environment. “Hazel is a tool for architects and planners,” she said. “The data help analyze cost, identify policy needs, streamline water detention practices, reduce carbon emissions, improve pedestrian thermal comfort, and create new habitats for wildlife.”
Ultimately, the platform provides data fundamental for project site selection. After being awarded a grant from the AIA College of Fellows Latrobe Prize, Hazel was developed collaboratively by the Arid Lands Institute of Woodbury University, Perkins+Will, the Nature Conservancy, and the City of Los Angeles. The design team is still refining Hazel. Christy notes that after presenting Hazel to architects and city planners, the response from the multidisciplinary audience was refreshing. “It was the first time I had someone come up to me and ask if I needed help coding,” she said.
Another software tool called SPEA (Spatial Practice as Evidence and Advocacy) was developed by a landscape architect–led team. “[We] are of course influenced by the architectural designers that we work with,” said McKenna Cole, research associate at SITU Studio. SPEA visualizes complex spatial narratives like the Euromaidan protests in Ukraine, often using three-dimensional renderings.
“Developing accurate 3-D models allows us to understand events spatially, enabling us to establish known protester and police locations that draws from citizen-captured videos,” explained Cole. The usual outlets for dissemination of the data collected and compiled with SPEA are in the courtroom, through specific publication, or in advocacy reports. SPEA received an honorary mention in the Equity + Inclusion category of the Place by Design competition at the conference.
If this most recent SXSW Eco was an illustration of the prominent role architects can play both as visionaries and as team players working to effect change, the conference also clearly demonstrated that opportunities abound and that people value design thinking. As William McDonough noted, “I’m an architect, and an architect’s job … is to change the way we see, then we rearrange the furniture, and then we build.”

The American Institute of Architects (AIA) announce the release of a new feature – developed in collaboration with Autodesk – that will automate the AIA 2030 Commitment data reporting from energy analysis software directly to the Design Data Exchange (DDx). This collaboration has resulted in an open Automated Program Interface (API) to the DDx, available to any energy modeling software vendor, reducing the duplication of effort using the existing process.
The new automated connection will allow the more than 350 AIA 2030 committed firms to report their project and portfolio performance to the DDx directly from Autodesk Insight 360, a technology addition included in Autodesk Revit and Autodesk FormIt 360 Pro subscriptions. This automated process between Insight 360 and DDx will eliminate the need for manual data entry and eliminates duplication of effort encouraging performance analysis and more frequent reporting throughout the design process instead of annually. The DDx interface is open source with the ability to connect with other energy modeling software providers. Additional vendors are welcome to link up with the DDx system.
Eliminating the overhead of manual reporting not only saves time but it also enables more regular updates so firms can get up-to-the-minute progress on their projects and portfolio. In terms of actually meeting the targets themselves one of the key findings of the 2014 progress report was the critical role that energy modeling plays, and how projects that applied energy modeling were generally higher performing.
For example, of the projects submitted in the 2014 reporting period, nearly 50 percent of the projects where an energy model was created met or came close to achieving the AIA 2030 Commitment goals, whereas 80 percent of non-model projects fell below the 40 percent target. This offering helps to lower the barriers to energy modeling, making it possible to conduct energy modeling on virtually every project, especially from the early stages, but in doing so automatic reporting to DDx is essentially free.

Perhaps no one is more grateful for the $12.8-billion investment to upgrade Ontario’s Darlington Nuclear Generating station than Justin Parrington.
“Without the refurbishment, I wouldn’t have a job,” said the young marketing sales executive at Burlington’s MarShield, during a roundtable discussion about the nuclear project last Friday.
MarShield makes protective gear for people who work in the nuclear industry from medicine to energy production. It is one of several local companies, and among 60 in the province, to reap the economic benefits of the provincial investment to upgrade the aging power plant.
Plenty of the specialty components, supplies, engineering expertise and research needed for the eight to 10-year long project are provided by local firms such as GE Power, Laker Energy Products, Platecon Projects, Stern Laboratories, Clean Harbours Canada and CTSNA Commissioning & Technical Services.
“The number of companies that will prosper from it are tremendous,” said Keith Hoey, president and CEO of the Burlington Chamber of Commerce. The chamber, as well as its provincial counterpart, gathered some of those local vendors together last week to speak with local politicians and the people behind the massive project.
Like Parrington at MarShield, Laker Energy is already experiencing an uptick from the upgrade.
The local company has grown from 20 to 60 staff, thanks to Darlington, said company president Chris Hughes.
“These are high-quality engineering jobs, and we will be up to 75 staff in the next 15 years,” he predicted.
But, as happy as Mark Zimny, president and CEO of Promation Nuclear, is for young people like Parrington who are finding work thanks to the Darlington investment, he’s concerned about the future, especially as Ontario competes with firms in Russia and France, for business in the nuclear sector.
“How will I retain my engineers without new deals to grow the sectors,” he asked. “What’s the long-term plan?”
Eleanor McMahon, MPP for Burlington says the province’s investment in refurbishing Darlington “shows nuclear energy is back in the game.”
She assured Zimny that the province is helping generate a skilled workforce for the industry through its educational policies. McMahon said the post-secondary graduation rate in Ontario is now at 85 per cent and the promise of free post-secondary education to families earning less than $50,000 will eliminate financial barriers for students.
As well as boosting the local economy and labour force, Burlington MP Karina Gould said the investment in nuclear power, of which Darlington supplies 20 per cent for the province’s energy needs, is a low carbon option that is better and cleaner for the environment.
Indeed Roy Martin, who has spent five years preparing for the refurbishment of Darlington as the project director for Ontario Power Generation, said that 97 per cent of the electricity generated by nuclear power is smog free and greenhouse gas free, and costs half as much to produce as other power generators in the province.
“Rebuilding the reactor will give us 30, to 40, to 50 more years of clean, low-cost power generation,” said Martin.

As we reported in our earlier blog post, The Rise of Outdoor Lighting, homeowners continue to place a high priority on renovating outdoor living spaces. Taking center stage in these renovations is outdoor lighting. The report says, “Outdoor lighting is the most common [system] upgrade, whether it is LED (28%), solar (23%) or other (17%).”
The emergence of LED lighting has been a game-changer in outdoor design. Unlike their conventional counterparts, LEDs do not have a filament that will burn out or break, and they have a significantly longer lifespan (50,000 hours or more, compared to 15,000 to 35,000 hours for conventional HID lighting ) – which make them extremely energy efficient.
Because LEDs are so durable and energy efficient, they’ve become the leader in outdoor lighting. They can be used anywhere on your property, from lighting walkways and steps to illuminating patios and outdoor living spaces. Here are a few ways high efficiency LEDs are playing a significant role in outdoor lighting design.
Lighting the Way – In outdoor landscaping design, lighting can be a visual cue for defining the entrance to a home. It can be as simple as additional walkway lighting to as multifaceted as using many options to create a dramatic illuminated pathway to the front door.
Marking the Perimeter – If you have a deck, LED rail lighting can offer a modest amount of light that can set the ambiance for an evening gathering while still marking the deck’s perimeter. Also, LED rope lighting is often used to outline raised flower beds and water features.
Adding a Layer of Safety – Once the sun sets, outdoor areas can be a bit more dangerous to navigate; however, LED lighting as a design element will add a layer of safety to steps. Lighting is often added to hardscape stairs, or as seen below with the LED Post Accent Light . In this scenario, the accent light attaches to the post face to create a warm, white light.
Putting Functionality into Outdoor Kitchens – To add more functionality to outdoor kitchens, LED flexible strips are being integrated into outdoor bar and cooking areas. These strips position nicely under cabinets or along the underside of countertops and provide the perfect accent lighting, as well as make the outdoor kitchen much more functional after dark.
Accenting Landscaping Elements – One of the key benefits of using LEDs in landscape design is that they can be positioned to emit light in specific directions. Up-lighting under trees, for instance, creates interesting shadows, sometimes referred to the “Frankenstein Effect.” Alternately, strategic positioning of up-lights allows them to illuminate an architectural detail of the home, or even a piece of outdoor artwork or sculpture.
As LEDs continue to extend their foothold into landscape design, so will technological advances – bringing with it creativity and inspiring ideas for all to enjoy.

Many electrical hazards exist in a workplace where workers are performing electrical-related tasks. One of those hazards is an arc flash.
An arc flash, as defined by the Workplace Safety Awareness Council is “a phenomenon where a flashover of electric current leaves its intended path and travels through the air from one conductor to another, or to ground.” A person located near an arc flash can be seriously injured or killed.
An arc flash can be caused by a variety of things, such as dust, dropping tools, accidental touching, condensation, material failure, corrosion, and faulty installation.
To protect workers, the National Fire Protection Association (NFPA) developed approach boundaries to be used by workers on or near energized equipment. They include:
Limited Approach Boundary: The minimum distance from an energized source where an unqualified person can stand. A qualified person who can enter that space is wearing proper PPE and been properly trained.
Restricted Approach Boundary: A shock protection boundary that can only be crossed by a qualified person who has been properly trained and is wearing proper PPE.
Prohibited Approach Boundary: A shock protection boundary that can only be crossed by a qualified person wearing PPE and been trained to work on energized conductors or components. Workers also must have a documented plan to perform the work before crossing this boundary.
Arc Flash Boundary: A safe approach distance from energized equipment or parts.
Some general ways in which you can protect workers from electrical hazards on the job are:
- De-energize the circuit
- Work practices
- Ground Fault Interrupters (GFCI)
- Grounding (secondary protection)

Watch this 14-day time lapse video which shows how Icynene spray foam insulation does not absorb water compared to other spray foams. Icynene spray foam insulation won't absorb or retain moisture like others. Icynene maintains an air seal even after seasonal building contractions.
Ever wondered how efficient your home really is? The U.S. Department of Energy has created a comprehensive and educational infographic that breaks down what a home energy audit is, what’s involved and how the results can help you and your clients determine the best investments to improve the home’s energy efficiency.
For instance, spray foam can be a wise investment to curb air leakage since the average home has enough gaps that add up to the size of a basketball. These gaps allows air leakage to occur. Check out the infographic below and then discover how spray foam insulation can help play a role in addressing common problems relating to interior comfort and air leakage.
When it comes to energy efficiency in the U.S., many people point to automotive carbon dioxide emissions as ground zero. It's a fair point – according to the EPA, between 1990 and 2012, the transportation sector accounted for 32 percent of all carbon emissions in the U.S. But in the realm of overall energy consumption, another industry is even higher.
The buildings sector – both residential and commercial – made up 41 percent of energy consumption in 2010, according to data from the Department of Energy. Those energy sources consist of coal, natural gas, petroleum, nuclear and renewables. Regardless of the source, building owners would be better served if they could conserve as much energy as possible without sacrificing comfort or aesthetics.
As it turns out, there are reliable, modern techniques that materials architects can rely upon to help reduce the amount of energy consumed by the buildings industry in the U.S. New buildings outfitted with air and moisture barrier systems and continuous insulation wall systems help maintain a comfortable interior by preventing unwanted airflow and heat transfer.
For builders, zero is the magic number
Net-zero homes – those that produce at least as much electricity as they use – are nothing new. However, only recently have they emerged as something other than a custom home for the supremely wealthy, reported The Wall Street Journal. That prior perception is not unwarranted, as net-zero homes often are expensive to build. But a few architects have made a push to bring the net-zero building to the mainstream.
These pioneers are driven by increasing demand, both from individual consumers and by way of increasing regulations regarding building emissions. With that said, the market is not yet to the point where every home and business owner is clamoring for a net-zero project. But some of that could be influenced simply by letting consumers know what is available.
Net-zero price point on the decline
As it stands, a net-zero house is still out of the price range for many. But where it was once the solely available to multi-millionaires, developers are working on homes that would appeal to upper-middle income families. Blue Heron Design/Build LLC told The Wall Street Journal it could build net-zero homes at a cost of around $700,000 – not low-income housing, but certainly more affordable than the designer homes that net-zero had become associated with.
"Net-zero is technologically and financially solved," C.R. Herro, vice president of environmental affairs at Meritage, explained to the WSJ. "It's now a matter of the consumer catching up to that potential. That's probably another three years."
In addition, the cost of energy-efficient systems has fallen in recent years as technology and installation methods improve. For example, solar-power systems' average installation cost has declined by 50 percent since 2010. Exterior wall insulation and similar systems provide financial benefits that help offset the initial cost.
While zero is difficult to achieve, many builders that seek energy neutrality will, at the very least, greatly reduce energy consumption. Last year, the Department of Energy certified a mere 370 homes as net-zero. But another 14,500 fell just short of net-zero specifications. For now, even the attempt at net-zero will yield significant energy savings.

The architects at Gensler approached us with their design challenge: How to incorporate light weight, grille-style wall cladding, built to accommodate light diffusers, in an aesthetically pleasing way that would be appropriate in a high-end corporate environment. The grilles would need to run floor to ceiling, be easily mounted and have soft edges. In addition, budget constraints required all of the above to be incorporated into a cost effective solution.
This project was large and complex, and due to the time constraints faced by project management, Advanced Arch Grilles did not meet with the contractor for this phase of the project until design drawings were already approved. A solid partnership was quickly forged; within two weeks, the contractor had on-site two complete sets of AAG110 aluminum, press locked and welded, linear bar grille core with mounting tabs and reinforcing stiffener bars with a satin, clear anodized finish. Our quick response time enabled the contractor to devise a mounting method and plan for installation many weeks in advance of actual delivery of the grilles.
The prototype cycle also proved valuable to our production team. During fabrication of the prototypes, our team developed solutions to ensure the vertical grille panels would install completely flat, and when positioned top-to-bottom and side-to-side, would be perfectly aligned.
Our engineering team, working alongside our production personnel, designed a method of “back side” support to overcome any material twist or deflection and also created a series of alignment and test jigs that assured the grilles were uniform and unvarying once installed.
The project progressed as expected and we proudly delivered every grille ahead of schedule. We consider ourself privileged to work seamlessly with such a highly regarded company and such a talented group of people, and to contribute to the successful completion of this project.
The built environment is an energy-guzzler. The U.S. Green Building Council (USGBC) states in this country alone, buildings account for 41 percent of energy use, 73 percent of electricity consumption and 38 percent of all CO2 emissions, and 13.6 percent potable water consumption. Globally, buildings use 40 percent of raw materials, or about 3 billion tons annually.* Fortunately, the type of doors we select can have a big impact on a building's energy profile.
Revolving doors provide a constant airlock at the entrance, reducing air infiltration by up to 90% compared to swinging or sliding doors. The result is energy savings, and an inviting and more spacious entrance area. If you’re ready for revolving doors, the possibilities are endless. Download the “Ins and Outs of Revolving Doors” to learn more about the features and design elements as they relate to user comfort and safety, as well as code requirements and a specification checklist.

Data centers today not only require protection from the elements, but also need to be designed to save energy as it is estimated they consume about 1.5 percent of all total demand. According to the Natural Resources Defense Council, data centers are one of the largest and fastest growing consumers of electricity in the United States. In the U.S in 2013 three million computer rooms used enough electricity to match the annual output of 34 large coal-fired power plants. Annual consumption is projected to increase by roughly 47 billion kilowatt-hours by 2020. The NRDC recommends that best-practice efficiency behaviours across the data center industry need to be adopted as demand rises to unprecedented levels.
Energy Savings in Data Centers through HVAC Equipment
Traditionally when a building needs cooling, compressors engage and fans start to move air over cooling coils. This cooled air is used to condition the internal environment where the temperature is required to be lowered. This process is extremely effective but requires costly compressor and fan energy, adding avoidable cost considering external building temperature is lower than the temperature inside. When the outdoor enthalpy (a combination of temperature and humidity) is preferred over the indoor enthalpy, conditions are suitable for “free cooling”. Depending on the geographic location of the facility, economizer cooling can represents a dramatic reduction in overall energy consumption.
An economizer is like a window that automatically opens itself – with the added advantage of going through the rooftop AC’s filtration system. An airside economizer simply recognizes the preferred enthalpy of the outside air. When enthalpy conditions are suitable for “free cooling”, the economizer controls position outdoor air, return air, and relief dampers to facilitate free cooling through the first and sometimes second stages of cooling.
Economizers can contribute to a reduction in data center power consumption by utilizing the cooler external building temperatures to assist in cooling the facility and equipment when required. In maximizing energy savings and reducing HVAC cooling load, the cooling system’s product life can be extended.
A study on building control systems by Battelle Laboratories found that, on average, the normalized heating and cooling Energy Use Intensity (EUI) of buildings with economizers was 13 percent lower than those without economizers. When an airside economizer works properly, the savings are significant. Whether your company is looking to burnish its environmental credentials, to lower the cost of operating its data center, or both, a properly designed system integrating an airside economizer is a cornerstone of achieving both goals.
Economizers and Indoor Air Quality (IAQ)
A confined, un-aerated indoor space within a building allows gaseous fumes, odors, germs, and even fungi to grow in concentration to the point that the indoor air is qualitatively different from the ambient air. IAQ is important because the health and the comfort of people working indoors are an important factor in sustainable productivity. Poor IAQ in a working environment can cause discomfort or health problems sometimes resulting in a loss of productivity, increased errors, and even litigation. With the added benefit of reducing cost in power consumption, introducing outside air into a building via economizers can also contribute to improving indoor air quality. Following the relevant ASHRAE standards that apply to ventilation, air movement and exhausting of contaminants ensures that IAQ requirements will be met. To meet the requirements of ASHRAE 62 the outside air entering a building should be measured and controlled.
The most important part of an airside economizer are the damper blades that allow the control and supply of a fixed amount of outside air into the building. Parallel bladed economizers do a better job of mixing the outside and return air to provide optimal benefit to the system. The sealing ability of the damper is essential to the system as a whole, when contending with extreme temperatures external to the building. AMCA certified dampers can ensure leakage rates meet the appropriate standards.
It has to be recognized that during different seasons and in different climates the benefits from economizers may vary.
Relevant Codes and Standards applicable to Data Center HVAC
- International Energy Conservation Code: IECC – Adopted by eight states and many local jurisdictions (according to ICC)
- ASHRAE 62.1, 62.2, and air movement
- ASHRAE Energy Standard 90.1 – Required for LEED projects and can be used in place of IECC
Featuring Ruskin’s exclusive one-piece galvanized airfoil blade and stainless steel jamb, the Economizers provide low-leakage performance as described in ASHRAE Standard 90.1. Each unit also features Ruskin’s “SUREFLOW” sensing tubes and blade position indicator to help determine minimum airflow. This also helps assist in mixed air temperature verses blade position field adjustments.
Data Center Protection
The Natural Resources Defense Council states that Data centers can be regarded as the back bone of a modern economy serving businesses and communications. Defending data means not only protecting it from Mother Nature but also giving back to her with sustainable designs. A question that must be considered during the design of a data center, is ‘How likely could the facility be compromised in extreme weather conditions such as tornadoes and hurricanes?’
When evaluating potential HVAC equipment it is advisable to use FEMA rated louvers and grilles. FEMA rated grilles and hurricane-resistant louvers have been tested against high windloads and large missile impacts. Outside air control dampers can seal up the center when necessary to reduce humidity and heat.
Ruskin’s XP500S Extreme Weather Grille protects wall penetrations from flying debris caused by tornadoes, hurricanes, and severe storms. This type of protection is critical in the design of Community Shelters (ICC-500) and Safe Rooms (FEMA 361). It offers designers a ventilation solution for their near-absolute life safety requirements. The heavy duty grille can be mounted internally, externally, or in conjunction with other louvers providing protection and certified performance. Rated for an industry leading 266 psf windload, the XP500S Grille meets or exceeds the building envelope protection requirements while complementing the construction of data centers.
