In 2011 SWA built the nation’s largest planned Zero-Net Energy (ZNE) community. Working in collaboration with the University of California Davis and developer West Village Community Partnership (WVCP), the project houses over 2,000 students and 500 staff and faculty families.
The members of Chicago‘s Building Owners and Managers Association (BOMA) control nearly 80 percent of downtown Chicago’s rentable building area. That makes them critical to local energy efficiency initiatives that aim to reduce the nearly 40 percent of U.S. energy that is consumed by buildings. Read More
Big Ass Fans are, as their name suggests, a producer of very large fans. They’re used everywhere from dairy barns to art galleries to outdoor public installations like Wendy, HWKN’s star-shaped pavilion for MoMA PS1’s summer Warm Up series. They also make residential models, like Haiku, the latest product in their line up. Once you get over the eye roll-inducing slogan—Haiku: Poetry in Motion—it’s a really incredible product. According to Energy Star it’s the world’s most efficient residential ceiling fan, and even exceeds their efficiency requirements by 450 to 750 percent. Whereas most fans use 90 to 100 watts, the Haiku uses just two to 30 watts, costing an average of $5 per year.
When construction was completed on the Empire State Building (ESB) in 1931 it cost $25.6 million—that’s just $9.20 per square foot. You can’t even build a single floor for that nowadays, much less a 1,454-foot tall skyscraper (adjusting for inflation, the ESB would cost $352 million today). Though the building hosts events and tour groups, most of us only see it from the outside and don’t realize that the reason it’s known as the World’s Most Famous Office Building is because tenants occupy the vast majority of its 102 floors. And like any other office building, lighting consumes the majority of its electrical costs—a whopping 39 percent.
In order to meet their stringent return-on-investment requirements, Anthony Malkin, President of Malkin Holdings, which owns the ESB, and Jones Lang LaSalle, an energy and sustainability consultancy, commissioned Lutron to supply pre-built tenant spaces throughout the building with sustainable lighting control solutions as part of the Clinton Climate Initiative Building Retrofit program aimed at improving efficiency and financial performance. The building-wide retrofit is projected to provide a total lighting energy savings of up to 65 percent and a reduced installed payback period of just 2.75 years. Overall, the Lutron system will reduce energy use by 38 percent and energy bills by $4.4 million per year. Moreover, the upgrade will prevent an estimated 105,000 metric tons of greenhouse gas emissions over the next 15 years.

A motorized green wall that reads the weather and adjusts automatically
Two years ago six students and three faculty from Virginia Tech’s School of Architecture + Design spent three weeks at SOM‘s Chicago office applying industrial fabrication solutions to the problem of high density housing for Southworks, a housing development that’s currently being planned for a large vacant section south of the city. The result was LumenHAUS, an aggressively energy efficient home that won the international Solar Decathlon Competition that June for sustainable solutions to high density construction. LumenHAUS is not only net zero, it actually creates more energy than it uses by implementing, among other innovations, a modular system that autonomously responds to external weather information and internal environmental conditions to optimize energy use. This Fall Virginia Tech’s Center for Design Research will begin construction on a full scale prototype of six housing modules, including a working prototype of Hanging Garden, a dynamic plant wall that reads the weather and responds by sliding along the walls and windows to either block or allow sunlight into the living unit.
