Sustainability goals for buildings are highly acclaimed as public and private sector’s contributions to environmental responsibility, resource efficiency, occupant comfort and well-being. All too often a building’s performance does not meet design expectations, particularly a new building’s energy savings projection that overstates achievable performance. Across the high-performing building industry, these unrealistic energy performance goals have come from, among other things, inadequate modeling and benchmarking practices, unreliable monitoring and equipment controls systems, and significant changes in space usage and tenant improvements. There is still lack of commitment to include operations staff in goal setting and provide adequate budgets for periodic benchmarking, commissioning, and tuning of buildings’ mechanical, electrical and plumbing systems. This paper provides the analytical, performance & prescriptive measures for life cycle assessment of energy efficiency projects which can help in making adaptive changes to buildings systems to suit changing uses, or other internal and external factors that directly or indirectly affect performance.
