Power performance assessment of building energy systems

Buildings are the main consumers of electricity. However, the focus of building domain has been on energy efficiency measurement and evaluation and we lack adequate measures to quantify and assess performance of building energy systems in terms of their power consumption. The significance of this issue is growing in parallel with the advancements of the smart power grid. This paper presents methods and measures needed to study and assess performance of buildings in the electricity system. To achieve this, a set of quantitative power performance indicators (PIs) is first defined. These PIs are consequently applied to a variety of building control strategies in the context of demand response (DR) scenarios to quantify, assess, and compare their performance.
