Abstract

Climate change and energy crises are the two challenges faced by societies. To address these issues, buildings have to be both flexible and resilient. The aim of this paper is to simulate and compare the performance of two types of a single-family house, i.e. an old building (1970) and a new building (2000), integrated with and without photovoltaic (PV) for the two objectives of energy flexibility and energy resilience in the cold climate of Finland. Depending on the PV size, it is found that the old building has a flexibility factor of up to 84% and the new building has 17% and the energy cost reduced. For resilience, the PV made the old building robustness period 15 h and the new building 32 h. With the PV, the amplitude of the buildings failure is lower and the recovery speed is faster. To meet future sustainability and resilience goals, energy resilience and flexibility for different types of buildings have to be studied together, which are impacted by both the characteristics of the bulding’s thermal mass and the onsite energy generation.
