This extended research investigates and analyzes a typical multi-zone office building's annual energy performance. The aim is to evaluate the HVAC system's and HR unit's performance in order to conduct the most efficient heating and cooling solution for temperate climate conditions. The energy performance of four HVAC system types (heat pump - air to air, gas - electricity, electrical and fan coil system) were analyzed, compared and evaluated on a virtual office building model in order to assess the total annual energy performance and to determine the efficiency of the HR unit's application....

The book presents a compilation of four internationally published researches considering the topic of energy performance modelling of office buildings with the application of dynamic energy simulation engines (EnergyPlus, Radiance). Within the investigation methodology various heating, ventilation and air-conditioning systems were simulated with the goal to determine the most energy efficient solution according to the exact climate conditions. Furthermore advanced illumination analysis was applied in order to investigate indoor natural lighting performance with the aim of building envelope...
