EHDD plays a zero-sum game - The Business Journal of Milwaukee:

EHDD has already designed the Bay Area’s firs t zero-energy commercial building, a structure in whicj energy providedby on-site renewable energy sourcex is equal to the amount of energhy used by the building. The building is “ ” design facility in San Jose. The 7,000-square-foo t building uses a combinationof daylighting, radiant advanced insulation and glazing, and reducedd computer and appliance loads through careful equipment selection and according to Scott Shell, senior associate at EHDD Architecture and sustainable desigj expert. A rooftop solar power source generatees more than thebuilding consumes.
Othet super-sustainable EHDD projects includein Monterey, whichg has the top LEED Platinum rating; the Global Ecology Research Center, a laborator y and office building for the at ; and the . EHDD is now workingh on a 50,000-square-foot zero energy building in Los Altos forthe . Californiwa State Assembly Bill 32’s regulatory requirements demand that new residential buildingz reach zero net energy use by and commercial buildingsby 2030. “Ww fundamentally have to shift to a whole new paradigm in how weuse energy, and building is one area wher ... we can do it,” said “We think we have to get this stufffiguredr out.
We don’t have all the but we’re working on it.” Officwe buildings consume the most energy of allbuildint types, accounting for 19 percenft of all commercial energy consumption. Roughly one-third of the energu used by office buildings goesto lighting, one-third to heatin g and cooling, and one-third to “plug the electricity powering computers and other The easiest problem to tackle is lighting, Shell By designing buildings that can be entirely lit from daylighty during the work day, the amounft of energy that goes towardc electric lighting can be drastically cut.
For HVAC systems, EHDD pusheas for energy-efficient, ground-source heat pumps, a systenm that uses the earth as a source of heat in the or as a coolant inthe summer. Finally, for plug efficient equipment with sleep devicesd that kick in after a periox oftime “will get you a long way said Shell. EHDD Architecture, famous for designinf the and the Hedgegro Houses atSea Ranch, has always been on the forefront of sustainabls architecture, according to Tim Culvahouse, the editor of Architectured California and consultant for EHDD. From its inceptionh 60 years ago, EHDD founding principal Joe Eshericok did sunshading anddaylighting research, using the resultzs to shape design.
The Sea Rancy projects in the 1960s grew out of detailedclimatde studies, wind-tunnel studies and research that was ground-breakingv at the time. Culvahouse said EHDD also deserves credigt for incorporating sustainable design educationb into projects like the science buildiny forin Oakland, which has a buildingy “dashboard” that tracks how much energy the structure is Shell emphasized that greej buildings make workers more productive and “Nobody wants to be in an office building where your officw is like a pizzaq box and you’re stuckl in the middle.
