Harvard University has achieved several firsts with the recent renovation of an old power plant into an office building. It is the first LEED Platinum certified university building renovation, as well as Harvard’s first Platinum building. More interestingly though, it is the first Platinum building built before the turn of the the century–last century, that is. Further, the university was able to complete this building without an increase in the up-front construction costs.

Since its inception in 1992, the ENERGY STAR program, a joint program run by the Environmental Protection Agency and the US Department of Energy, has sought to protect the environment by promoting energy efficiency. Starting with personal computers and monitors, ENERGY STAR established energy usage guidelines that set the bar for energy conservation. Over the years the ENERGY STAR program has brought just about anything that uses energy or water under its umbrella, saving an estimated $14 billion in energy costs in 1996. LEED for Homes and the NAHB’s Model Green Building Guidelines both encourage green home builders to use ENERGY STAR rated appliances. For those seeking additional credits - and energy savings - both green building programs encourage the use of very efficient clothes washers. But what exactly is a very efficient clothes washer?
A very efficient clothes washer saves both water and energy. Water Factor (WF) measures the number of gallons per cycle per cubic foot that the washer uses. In order to qualify as a very efficient clothes washer, it must have a WF of less than 5.5. To put that number into perspective, washers that have a WF of 8, the maximum for an ENERGY STAR labeled clothes washer, use up to 10,000 gallons of water a year. One of Asko’s UltraCare clothes washers boasts of a WF of 3.4, using under 3,000 gallons of water a year. Granted, at 1.9 cubic feet the Asko model is quite small, but if water efficiency is the goal, Asko sets the standard.
