Energy performance analysis of airport terminal buildings by use of architectural, operational information and benchmark metrics

Abstract

Airport terminal buildings are one of the most energy-intensive building types, and their constituents can include several types of spaces in one-roof structures. However, they have been rarely included in several energy-related studies due to the complexity of their mechanical and operational systems. The purpose of this research is to propose benchmark metrics to investigate the energy performance of existing and future airport terminal buildings. By using measured data of total 30 existing ones in North America and simulated results of total 90 specific space type models, a more improved multivariate regression model can refine the values for average of energy use. When revalued from their characteristics based on the refined average, energy performance forecasts are improved by from 1.1% to 3.0% as compared to the case of the simple average. In addition, it can be used to define a higher energy baseline reflecting some weights adjusted by the building characteristics and to apply it into the space configurations for new airport terminal buildings.
