The demonstrational Pavilion, designed to achieve the Bulgarian nearly Zero Energy Building (nZEB) standard, will be the first of its kind, using external and internal glass walls as heating and cooling devices. The glass envelope is composed of Water Flow Glazing (WFG) modules which will be used on the east. west and south façades. The circulating water inside the glass panes provides the energy needed for thermal conditioning of the Pavilion. Air-to-water heat pump ensures that the temperature of the water inside the WFG modules is kept within the predefined comfort levels. The roof, floor and north façade will be well insulated and will thus contribute to the low energy requirements of the Pavilion. A 6 kWp roof-mounted photovoltaic system will cover the electricity demand of the Pavilion and will additionally contribute to achieving the nZEB standard. In this paper we use the IDA ICE program to simulate the energy consumption of the Pavilion during the different seasons. We assume that the Pavilion is an office building with temporary occupancy during the opening hours - 8:00 until 18:00 on Monday to Friday and 8:00 until 14:00 on Saturdays. The main parameters considered in the simulations are consumption from the lighting facility, HVAC system, office equipment and the climate parameters – solar irradiance, ambient temperature, humidity, etc.
