Title: Energy Cost Impact of Non-Residential Energy Code Requirements

The 2012 International Energy Conservation Code contains 396 separate requirements applicable to non-residential buildings; however, there is no systematic analysis of the energy cost impact of each requirement. Consequently, limited code department budgets for plan review, inspection, and training cannot be focused on the most impactful items. An inventory and ranking of code requirements based on their potential energy cost impact is under development. The initial phase focuses on office buildings with simple HVAC systems in climate zone 4C. Prototype building simulations were used to estimate the energy cost impact of varying levels of non-compliance. A preliminary estimate of the probability of occurrence of each level of non-compliance was combined with the estimated lost savings for each level to rank the requirements according to expected savings impact. The methodology to develop and refine further energy cost impacts, specific to building type, system type, and climate location is demonstrated. As results are developed, an innovative alternative method for compliance verification can focus efforts so only the most impactful requirements from an energy cost perspective are verified for every building and a subset of the less impactful requirements are verified on a random basis across a building population. The results can bemore » further applied in prioritizing training material development and specific areas of building official training.« less
