Thermal Loads Map and Overall Energy Analysis Depending on Low-Effort Parameters Change: A Commercial Building Case Study

Starting from the second half of 2022, energy market, in particular, European natural gas supply, passed through an eventful period. The sanctions imposed on Russia because Ukrainian war rearranged steadiness suppliers to continent, and major concerns arose regarding reduction primary consumption, particularly for heating cooling purposes. This study proposes a method mapping loads building as function effortlessly changeable boundary conditions (i.e., heating/cooling temperature set-point, infiltration rate work shift); simulation thermal well final estimation was carried out with DesignBuilder, Energyplus-based software, dynamic calculation approach. Thermal load maps provide immediate picture achievable savings represents effective tool monitoring; addition, can support managers policymakers rapidly complying unexpected scenarios. has been applied non-residential results showed that up 40% could be reached, ensuring adequate indoor comfort. Finally, analysis benefit switching fossil fuel boilers electric heat pumps space due minimum saving 70%.
