The article presents a passive building to be used for office purposes that is under construction in Podlaskie region. The building has been designed to meet the characteristics of a passive building – i.e. compact shape, mechanical ventilation with heat recovery, ground heat exchanger, tight external partitions with an indicator U < 0.15 W/(m2∙K), heat pump, solar collectors. Calculation indicator of useable energy demand for heating purposes is <15 kWh/m2∙a. In order to verify the achieved effects the building was subjected to tightness test and infrared camera tests are also planned. The building is constructed by the Podlaskie Passive Building Center as part of a project funded by the European Regional Development Fund.
