Many North Americans are willing to act to slow global climate change and respond to rising energy prices, but we cannot reduce our collective carbon footprint to sustainable levels unless we boldly address the energy use of existing homes, which accounts for 21% of US greenhouse gas emissions. Deep energy reductions will not overcome the cost, complexity, and implementation challenges if each house is addressed as a unique customized project. Much as with the BOPs (Builder Option Package) approach to new construction, a variety of verified packages are needed that demonstrate the optimization of systems to address energy, indoor air quality (IAQ), and durability issues. The THC offers the potential for many comprehensive house packages to be developed, refined, and tested in response to the specific challenges and opportunities. Deep energy reduction packages offer a way to bring integrated design to existing homes. For more information about this seminar, please contact: Jim Lutz(510) 486-7302
