The expansion project of the Vancouver Convention Centre was designed to be a showcase sustainable building and has been designed constructed to meet the LEED Gold Standard in sustainable building design. It features a sweeping green roof that is the 2nd largest in North America.
Steven Chu, U.S. Department of Energy (DOE) Secretary has announced up to $338 million in Recovery Act funding for the exploration and development of new geothermal fields as well as for research into advanced geothermal technologies. The newly announced grants will be awarded to 123 projects in 39 states and will be matched more than one-for-one with an additional $353 million in private and non-Federal cost-share funds, for a total grant pool of $691 million. This is a pretty big number and represents a major investment in a promising and yet often overlooked renewable energy resource. Recipients of the new grant funding include private industry, academic institutions, tribal entities, local governments, and DOE’s National Laboratories.
Are most homebuyers interested in purchasing a home that saves 90% over a traditional home on heating and cooling costs and requires only a small active heating system the size of a hairdryer? The Passivhaus movement is an exciting building design concept that offers tremendous energy savings due to reliance on passive heating systems. Europe is embracing the concept with between ten and fifteen thousand houses already built and governmental support of mandating the standard. The Passivhaus Institut in Darmstadt was formed in 1996 to promote and control passive house design and the group only recently formed the Passive House Institute US (PHIUS) to reach out directly to the US building market. It is slow to gain momentum, but holds promise for the US market in the future.
Speaking in Fort Wayne, Indiana where he was touring a manufacturer of geothermal heating pumps (GHPs) U.S. Energy Secretary Steven Chu announced nearly $50 million from the American Reinvestment and Recovery Act to advance the commercial deployment of this proven energy efficiency technology.
Geothermal heat pumps (GHPs), also known as ground-source heat pumps, are similar to ordinary heat pumps, but use the thermally stable mass of the earth below the ground instead of outside air to provide heating, air conditioning and, in most cases hot water as well. Because these systems use the earth’s natural reservoir of stable temperatures, they are among the most efficient and comfortable heating and cooling technologies around. GHPs can save substantial amounts of energy and significantly reduce peak demand in buildings that incorporate them.
