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 This 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 publication 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 is Online 2, including updating the LCA and LCC results using up-to-date methodologies and data available sources, with focus on the largest and most widely viewed product categories. free Keywords of Building economics; life cycle costing; life cycle assessment; life cycle impact assessment; charge residential buildings; commercial buildings; sustainability; green buildings from: https://doi.org/10.6028/NIST.TN.2032r1 i _____________________________________________________________________________________________________ Preface This documentation was developed by the Applied Economics Office (AEO) in the Engineering Laboratory (EL) at the National Institute of Standards and Technology (NIST). The document explains how the BEES database was developed, including the assumptions and data sources. The intended audience is BEES users, researchers and decision makers in the building sector, and others interested in building sustainability. This publication Disclaimers The policy of the National Institute of Standards and Technology is to use metric units in all its published materials. Because this report is intended for the U.S. construction is available industry that uses U.S. customary units, it is more practical and less confusing to include U.S. customary units as well as metric units. Measurement values in this report are therefore stated in metric units first, followed by the corresponding values in U.S. free customary units within parentheses. of charge from: https://doi.org/10.6028/NIST.TN.2032r1 ii _____________________________________________________________________________________________________ Acknowledgements The BEES tool could not have been completed without the help of others. Thanks are due the NIST Engineering Laboratory (EL) for its support of this work. The EPA Office of Research and Development, Sustainable Technology Division TRACI team were instrumental in developing the life cycle impact assessment methods incorporated into BEES. The author is particularly grateful for the key cooperation and support offered by a wide This variety of industry associations and manufacturers with products represented in BEES. Their publication cooperation exceeded all expectations and led to a significant expansion and refinement of the underlying BEES performance data. The authors wish to thank all those who contributed ideas and suggestions for this report. They is include Douglas Thomas and Dr. David Butry of EL’s Applied Economics Office, Stuart Dols of available EL’s Energy and Environment Division, and Dr. Nicos S. Martys of EL’s Materials and Structural Systems Division. free of charge from: https://doi.org/10.6028/NIST.TN.2032r1 iii _____________________________________________________________________________________________________ Author Information Joshua Kneifel Economist National Institute of Standards and Technology Engineering Laboratory 100 Bureau Drive, Mailstop 8603 This Gaithersburg, MD 20899 8603 Tel.: 301-975-6857 publication Email: [email protected] Priya Lavappa is Computer Specialist available National Institute of Standards and Technology Engineering Laboratory 100 Bureau Drive, Mailstop 8603 free Gaithersburg, MD 20899 8603 Tel.: 301-975-4522 of Email: [email protected] charge Brian Polidoro from: Computer Specialist National Institute of Standards and Technology https://doi.org/10.6028/NIST.TN.2032r1 Engineering Laboratory 100 Bureau Drive, Mailstop 8633 Gaithersburg, MD 20899 8633 Tel.: 301-975-6445 Email: [email protected] Anne Landfield Greig Principal Four Elements Consulting, LLC Seattle, WA Tel: 206-935-4600 Email: [email protected] iv _____________________________________________________________________________________________________ Contents Abstract .................................................................................................................................................................. i Preface ................................................................................................................................................................... ii Acknowledgements ............................................................................................................................................... iii Author Information................................................................................................................................................ iv Contents ................................................................................................................................................................. v List of Acronyms.................................................................................................................................................. xv This 1 Introduction to BEES ..................................................................................................................................... 1 1.1 BACKGROUND ........................................................................................................................................... 1 publication 1.2 BEES MODEL ............................................................................................................................................ 1 1.3 NOTABLE CHANGES IN BEES ONLINE 2 ............................................................................................................ 3 1.4 SUBMISSION PROCESS TO BEES ONLINE 2 ........................................................................................................ 5 2 Environmental Performance ........................................................................................................................... 9 is 2.1 GOAL AND SCOPE DEFINITION ..................................................................................................................... 10 available 2.2 INVENTORY ANALYSIS ................................................................................................................................ 12 2.3 LIFE CYCLE IMPACT ASSESSMENT .................................................................................................................. 13 2.4 IMPACT INTERPRETATION ........................................................................................................................... 27 3 Economic Performance ................................................................................................................................ 35 free 3.1 STUDY PERIOD ......................................................................................................................................... 35 of 3.2 LIFE CYCLE COSTING .................................................................................................................................. 36 charge 3.3 DISCOUNT RATE ....................................................................................................................................... 36 3.4 COST OF CARBON ....................................................................................................................................
