he US National Institute of Stan- dards and Technology (NIST; Gaith- ersburg, MD) Manufacturing Extension Partnership (MEP) site (www.nist.gov/ mep) describes a sustainable approach to manufacturing as “one that merges environmental, societal and economic concerns. Continual improvement is necessary in these three areas in order to secure the future of companies, communities, supply chains and the en- vironment…. Companies that commit to implementing eco-friendly changes fi nd themselves with lower operating costs, access to new markets and a more profi table enterprise.” MEP sustainability programs include E3 – Economy, Energy, and Environ- ment, a federal-local coordinated effort that helps manufacturers assess production processes and assists with the implementation of energy-saving projects, and the Building Construction Technology Extension Pilot (BCTEP), which focuses on training building op- erations staff to retune energy systems in smaller commercial and industrial buildings. Commercial buildings ac- count for almost 20% of the total US energy consumption, with 10-30% of the energy used wasted due to im- proper and ineffi cient operations. Energy analysis and optimization is an ongoing process. A novel energy demand modeling approach for CNC machining based on function blocks is described in a paper by Tao Peng, Xun Xu and Lihui Wang in SME’s Journal of Manufacturing Systems (http://tinyurl. com/JMS-functionblocks). Among other merits, the approach aids recon- fi gurability for different modeling tasks,
