Post-occupancy evaluation, or POE, is a diverse practice that can feed back data into the design process on everything from energy and water consumption to workplace satisfaction and even occupants' sleep cycles.
Architects and engineers must consider a building site's climate to create structures that efficiently keep occupants comfortable. Some new tools help buildings to perform as anticipated and gracefully adapt to a changing climate.
Designed to be the greenest commercial building in the world, the six-story structure is outperforming its energy goals with an integrated design and motivated tenants. The Bullitt Center used 75 percent less energy than a new building that meets Seattle’s rigorous energy code. The designers of Seattle’s Bullitt Center have overachieved. The Miller Hull Partnership, co-founded by the late Robert Hull, set out to demonstrate that a six-story office building could generate all of the energy it needs, but after one year of operation, it is sending a sizable energy surplus to the local power grid, according to data released
The Apple Store isn't a place you would typically look for residential building components. But you can find a new Wi-Fi-enabled lighting system from Philips called HUE there. This screw-in LED replacement for traditional bulbs can be easily controlled for color, color temperature, and intensity from a computer or smartphone.
Buildings are the source of one half to three-quarters of greenhouse-gas emissions in most American cities. Los Angeles, Boston, Chicago, Houston, and six more large cities have joined forces to tackle the problem by targeting their biggest buildings. “The largest buildings tend to be 3 to 4 percent of the overall number of buildings but account for 40 to 50 percent of the square footage and energy consumption. You have this terrific opportunity to work with a handful of buildings and make a big dent,” says Laurie Kerr, director of the City Energy Project (CEP), which launched in late January.
Creating buildings that deliver on progressively more ambitious environmental goals will require energy simulations that reliably predict post-occupancy consumption. Higher energy performance has evolved from an aspiration to an expectation. Owners of buildings—especially those certified under rating systems like LEED—increasingly count on an energy savings payback. And a wave of “net zero energy” buildings promises to generate enough energy on-site from renewable sources to equal or exceed demand. As a result, predictive energy models face new scrutiny. “In the last five years, energy modelers have learned that they will have to answer for their models,” says Laurie Canup, an associate
