Building for Environmental and Economic Sustainability (BEES) Online 2.1 Technical Manual



Joshua D. Kneifel, Anne Landfield Greig, Priya Lavappa, Brian Polidoro


Building stakeholders need practical metrics, data, and tools to support decisions related to sustainable building product selection. The Engineering Laboratory of the National Institute of Standards and Technology (NIST) has addressed this national need by developing a new version of its metrics and tools for sustainable building products, known as Building for Environmental and Economic Sustainability (BEES) Online. BEES Online 2 implements the same BEES framework using metrics based on process-based life-cycle assessment (LCA) and life-cycle costing (LCC) approaches to assess the environmental and economic performance of building products. BEES Online 2 includes a more user-friendly interface with more expansive user customization, options, and guidance. Most products in BEES Online 1.0 (all major product categories) as well as new products not in BEES Online 1.0 have been transitioned to BEES Online 2, including updating the LCA and LCC results using up-to-date methodologies and data sources, with focus on the largest and most widely viewed product categories.
