Inter-building effect: Simulating the impact of a network of buildings on the accuracy of building energy performance predictions

► We simulate the energy performance of a realistic block of residential buildings. ► We study buildings' mutual impact on energy requirement in different climates. ► We propose a systematic method for assessing this effect: the Inter-Building Effect. ► We find important energy requirement modeling inaccuracies if IBE is neglected. ► IBE must be considered in order to accurately predict building energy performance.
