Petersen Mfg. Co., Inc. Concrete & Steel Furnishings CAN I EXCHANGE THIS? Energy and water usage present challenges to sustainability-minded facilities, and in particular, laboratory spaces. In Pasadena, the California Institute of Technology's newly renovated Linde + Robinson Lab for Global Environmental Science uses various innovative methods of cooling with water. In the laboratory space at this facility, scientific equipment is cooled by a heat exchange interface system (seen on page 54). Water Is the Next Challenge Water usage is taking over at the forefront of designer considerations in laboratories. New water use regulations for federal agencies that mandate 26 percent reduction in potable water by 2020 relative to a 2007 baseline are already in place (Presidential Executive Order 13514). This puts great stress on laboratories that are dependent on water for cooling and other processes but now must conserve. Executive Order 13514 mandates reducing federal agency industrial, landscaping, and agricultural water consumption 2 percent annually or 20 percent by the end of fiscal year 2020, relative to a 2010 baseline. States like California have legislation that sets an overall goal of reducing per capita urban water use by 20 percent by Dec. 31, 2020. Starting in 2016, failure to reduce water consumption by at least 10 percent could result in the loss of eligibility for state water grants or loans for urban retail water suppliers. All of these regulations are working to resolve the fact that literally millions of gallons a year of potable or conditioned water are being wasted. This is particularly true in research facilities. With the plug-and-play utility spine, lasers, mass spectrometers, thermal analyzers, specimen freezers, spot coolers, and even ice makers can be installed wherever and whenever needed without being required to purchase additional unitary chillers to cool the equipment. These unitary chillers can often use up to 10 times the amount of electricity to generate cool water than a central building chiller system and often reject large amounts of heat back into the lab, forcing the building HVAC system to work even harder to remove the heat. Some unitary chillers and analytical equipment still use tap water to cool their equipment and then dump that water down the drain. Planters Bollards Tables Benches Ash Urns Drinking Ftns.
