WASHINGTON, D.C.—Plumbing inspectors, manufacturers, engineers, contractors, labor representatives and other industry technical experts in Las Vegas voted overwhelmingly to make a change to plumbing codes that will ensure hot water pipes in new homes and commercial buildings are insulated. Overall, insulation of hot water pipes will shorten the amount of time spent waiting for hot water at showers and faucets, and cut hot water waste by 15 to 30 percent. The vote took place during the review of proposed changes to the International Association of Plumbing and Mechanical Officials (IAPMO) Uniform Plumbing Code. The proposal was championed by the United Association of Journeymen and Apprentices of the Plumbing and Pipefitting Industry and the Natural Resources Defense Council. “Everybody wins by requiring insulation of hot water piping,” said Mike Massey, Executive Director, Piping Industry Progress & Education Trust Fund. “This was made possible by a joint effort of the NRDC and the UA and represents what can be achieved for the greater good of all of us when we work together.”
BERKELEY, CALIF.—Looking strictly at the economic costs and benefits of three different roof types—black, white and “green” (or vegetated)—Lawrence Berkeley National Laboratory (Berkeley Lab) researchers have found in a new study that white roofs are the most cost-effective over a 50-year time span. While the high installation cost of green roofs sets them back in economic terms, their environmental and amenity benefits may at least partially mitigate their financial burden. A new report titled “Economic Comparison of White, Green, and Black Flat Roofs in the United States” by Julian Sproul, Benjamin Mandel, and Arthur Rosenfeld of Berkeley Lab, and Man Pun Wan of Nanyang Technological University in Singapore, provides a direct economic comparison of these three roof types. The study appeared in the March 2014 volume of Energy and Buildings and was recently published online. “White roofs win based on the purely economic factors we included, and black roofs should be phased out,” said study co-author Rosenfeld, a Berkeley Lab Distinguished Scientist Emeritus and former Commissioner of the California Energy Commission.
NEW YORK—Greenwood Energy, the North American renewable energy division of the Libra Group, announced the installation of a 500-kilowatt (kW) combined heat and power (CHP) plant at the Millennium Hilton Hotel in Lower Manhattan. This is the first CHP plant Greenwood has developed for Millennium Hotel and Resorts in New York City, and Greenwood is currently developing an additional plant at the Millennium Broadway Hotel in Times Square.

MILWAUKEE, WIS.—Telkonet, Inc., whose complementary business divisions include EcoSmart, an energy management technology platform featuring Recovery Time technology and EthoStream, one of the largest high-speed Internet access providers in the world, announced that Mode:Green has standardized on Telkonet as best-in-class energy management technology for future projects.
BURNABY, B.C.—According to the U.S. Department of Energy, 400 billion KW of hot water goes down the drain annually in the United States—roughly $40 billion worth of energy at an average cost of $.10/KW. A great deal of that energy loss occurs in hotels—where energy is uncaptured from greywater from showers and baths, sinks, dishwashers, laundry, etc. Energy is also lost in the blackwater coming from toilets. One company, International Wastewater Systems, has developed a system it calls SHARC (which stands for sewer heat recovery) to capture and reuse heat that typically is lost to the sewage system. International Wastewater Systems, based in Burnaby, B.C., has installed its SHARC system in several buildings, including a 172-unit condominium complex in Vancouver, B.C. While International Wastewater Systems has not yet installed SHARC in a hotel, company founder and president, Lynn Mueller, said the system is ideal for a hotel building. Green Lodging News asked Mueller how his system works and what equipment is required.
BOURNE, MASS.—Chilled water system performance is often overlooked in plant operations, yet optimizing performance can significantly improve chilled water plant efficiency, and thereby reduce costs.
SANTA CLARA, CALIF.—WattStopper has introduced a new line of wireless occupancy sensors in response to customer requests for more choices to manage energy. The radio frequency (RF) products make it easy and cost effective to install code-compliant controls in existing buildings, or wherever wired occupancy sensors aren’t the best fit. The product line includes dual relay controls not available from other manufacturers, as well as time-saving functionality.
MINNEAPOLIS—Swegon Inc. announced its North American launch of the ADAPT Parasol comfort module, a hybrid product uniting the energy-saving and comfort advantages of chilled beams and demand control ventilation. “The ADAPT Parasol is the first of Swegon’s demand controlled ventilation products to be modified to meet North American Industry standards,” said Mike Woolsey, President at Swegon “This follows the successful launch of ADAPT Parasol in Europe last year.”
