  • e-News #52: Low-Energy Lab Design
    December 1, 2005
    1 comments

    It's no easy undertaking to design a high-performance laboratory building that uses very little energy while meeting comfort, health, safety and programmatic requirements. Laboratory buildings typically have very energyintensive heating, ventilation and air conditioning (HVAC) systems that operate 24 hours per day and use 100 percent outside air.

  • e-News #38: Battling the Big Box Energy Bite–Lessons for Large Retail Design
    June 7, 2002

    There's been a big explosion in big box retail buildings: In 1970, there were an estimated five square feet of retail space for each person in the U.S. By 2000,that figure had risen to 20 square feet per capita. Since the large retail (greater than 10,000 square feet) segment is the second greatest energy user of all commercial segments, the implications of this growth trend are significant.
