FES-East – June 3, National Defense Center for Energy and Environment Objectives This presentation will provide an; –Overview of current Greenhouse Gas (GHG) Policy. –Introduction to SWS and impact on GHG emissions. –Impact analysis for demolition vs. deconstruction waste management alternatives. o DoD Family Housing o Single Story Duplex

FES-East – June 3, National Defense Center for Energy and Environment GHG Emissions Related to Buildings United States (U.S.) Energy Information Administration states that buildings are responsible for almost half (48%) of all GHG emissions annually Each year, the U.S. buries about 33 million tons of wood related construction and demolition (C&D) debris in landfills As wood decomposes, it will release 5 million tons of carbon equivalents in the form of methane gas –Equivalent to the annual emissions of 3,736,000 passenger cars

FES-East – June 3, National Defense Center for Energy and Environment Federal Policy Presidential GHG Emissions Reduction Goals –“President Bush announced a new national goal to stop the growth in U.S. greenhouse gas emissions by 2025.” On April 16, Executive Order (EO) “Strengthening Federal Environmental, Energy, and Transportation Management” –“Federal agencies are required to improve energy efficiency and reduce greenhouse gas emissions....” –“Agency heads are also ordered to implement within the agency sustainable practices for energy efficiency, greenhouse gas emissions avoidance or reduction..., and pollution and waste prevention and recycling...”

FES-East – June 3, National Defense Center for Energy and Environment GHG Reduction Accords Kyoto Protocol - –International treaty that calls for 6% reduction of GHG emissions in Canada and 5% in the U.S. Urban Environmental Accord –Composed of twenty-one policy actions geared toward environmental sustainability at the urban level. –Goal of 25% reduction in GHG emissions by 2030 Governors Rally for Climate Change –Over a dozen governors across the U.S. signed the Declaration on Climate Change April 21, 2008.

FES-East – June 3, National Defense Center for Energy and Environment Alternative Waste Management Practices What is Deconstruction? –It is a process by which a building is disassembled in a reverse order to the process of construction. –Deconstruction, as opposed to demolition, is considered an organized and systematic method, as materials need to be separated at the source in order to maximize landfill diversion through reuse and recycling.

FES-East – June 3, National Defense Center for Energy and Environment Analysis Approach Select a candidate building and evaluate it using the available software. Compare traditional waste management practice of demolition and landfilling to deconstruction and recycling. Calculate the difference in GHG emissions between waste management practices. Compare select products for building systems relative to GHG.

FES-East – June 3, National Defense Center for Energy and Environment Analysis Approach Validation of data through software packages –NDCEE Decon 2.0 – Available Pending Approval. –Environmental Protection Agency (EPA) WAste Reduction Model (WARM) –National Institute of Standards and Technology (NIST) Building for Environmental and Economic Sustainability (BEES) - –Athena Institute ATHENA® EcoCalculator for Assemblies -

FES-East – June 3, National Defense Center for Energy and Environment Analysis Approach Decon 2.0 – Software tool designed to assist users in planning for a deconstruction project. User inputs building characteristics to assess the feasibility of a deconstruction project. The software tabulates material quantities anticipated from demolition and deconstruction. WARM – Software tool that helps solid waste planners track and report GHG emissions reductions from waste management scenarios. BEES 4.0e – Software tool allows users to select cost- effective, environmentally-preferable building products ATHENA® EcoCalculator – Software tool designed to calculate environmental impacts associated with the assemblies used in your building

FES-East – June 3, National Defense Center for Energy and Environment Conclusions Deconstruction along with proper material selection can result in reductions in GHG emissions Decon 2.0 Analysis suggests certain DoD buildings are good candidates for deconstruction WARM Analysis shows that deconstruction activities can decrease GHG emissions BEES Analysis: when analyzing the global warming by life-cycle stage, raw materials acquisition contributes the most to GHG emissions BEES Analysis identified carbon dioxide as the most prevalent GHG emission Deconstruction can help the DoD meet EO 13423

FES-East – June 3, National Defense Center for Energy and Environment Next Steps Incorporate GHG emissions calculator into Decon 2.0 Continue to assist installations in validating carbon credit for innovative waste management alternatives to meet anticipated GHG tracking and reporting requirements. Assist installation in identifying alternate funding sources for meeting new federal GHG policy goals. Identify emerging building materials and technology alternatives most suitable for solid waste sustainability, energy efficiency, and reduction of GHG. Provide technology transfer for alternatives tailored to meet new DoD-wide solid waste sustainability policy.
