Claims of high performing buildings made but little evidence presented to verify Establish common set of measurements with results reported against meaningful and consistent benchmarks. Reliable and reproducible protocols needed to give usable feedback to designers/operators when measured performance does not match design intent and expectations 3.

Case Study: ashrae Headquarters Maintain to Sustain Modern air conditioning systems protect the health, comfort and productivity of Building occupants. Unfortunately, they consume a lot of Energy while providing these benefits. When these systems are not operated properly, the Energy they use can increase by 50 percent or more. The elimination of non- value producing Energy helps protect our environment while saving the Building owner money.. - ashrae Presidential Member William Harrison 4. 12/18/2013. Maintain to Sustain Reduction not so much the result of changes in hardware and systems. Reduction comes from improvements in software and operational training.

3 Study by the Energy Systems Lab at Texas A & M University indicated Energy use in buildings could be reduced by 10% to 40% by improving operational strategies in buildings. Over reliance on expert knowledge has resulted in minimum transfer of knowledge. Standards and Guidelines Guideline 32-2012, Sustainable, High performance Operation and Maintenance Provides guidance on optimizing O&M to achieve lowest economic and environmental life cycle cost without sacrificing safety or functionality Assists those who operate and maintain buildings to achieve high performance : safe, productive indoor environments; low economic life cycle cost; low Energy , water and resource use;. and low impacts on environment Applies to all buildings, not just new ones 5. 12/18/2013.
