According to the EPA, in 2008 commercial buildings energy usage was: - 38% space heating 20% lighting 8% water heating 14% cooling and ventilation Features of Sustainable Practices: - -Site selection analysis considers factors like community connectivity, accessibility to mass transit, opportunities to share parking and avoid building on sensitive land - Waste and pollution reduction - The design and implementation of energy and water efficient systems 3© EMILY CHARLENE YEAR , ALL RIGHTS RESERVED - Team members work in coordination through a holistic integrative approach - Operation and maintenance cost reduction The US General Services Administration Green Building benefits are quantified as: - 13% lower maintenance costs 26% less energy usage 27% higher level of occupant satisfaction 33% lower CO2 emissions Triple Bottom Line: - People (social) Planet (environmental) Profit (economical) Social Benefits (TBL) - - better indoor environmental quality - healthier environment - no extra burdens on local infrastructure Environmental Benefits (TBL) - - protect wild life - no air or waste pollution - no extra waste production - prevent natural resources depletion Economic Benefits (TBL) - - lower operating and maintenance costs - higher property value - higher employee productivity - lower life cycle costs 4© EMILY CHARLENE YEAR , ALL RIGHTS RESERVED Life Cycle Assessment (LCA) - Analyzes the environmental impacts of a service, material, or product through its entire life cycle Evaluates a material's life cycle with respect to: -energy -emissions -waste Life Cycle Cost (LCC) - Assessment of building cost from "cradle-to-grave", life cycle costs considers all factors from initial costs, health issues, productivity to potential building reuse after demolition Embodied Energy - the energy consumed during the different stages of a material's life cycle and is included in its life cycle assessment Hard Costs - Costs related to construction phases life c
