Performance of Industrial and Residential Near‐zero Energy Buildings

This chapter presents a comprehensive approach for evaluating the performance of one industrial and one residential smart/near‐zero energy building. The research activities performed and presented in this chapter target the estimation and evaluation of the performance gap between the design and operational phase of zero energy buildings. The steps are as follows: selection of the case study buildings; analysis of the buildings and their systems' design and an assessment of power and energy requirements through dynamic thermal simulation models; data collection while the buildings are in operation; and a comparison of the results of the buildings and the extraction of useful remarks and conclusions. The chapter analyzes the Leaf Lab's energy performance and compares modeling results with real‐time data. There is a systematic and continuous approach in establishing near‐zero energy targets, through research and innovation activities.
