The present paper describes a technical-economic analysis of thermomodernization works in multifamily buildings and public utility facilities constructed with the use of both traditional and industrialized technologies (prefabricated large-panel concrete, Zeranska brick), built before 1990. 1441 buildings located in 7 towns were analysed. The energy consumption indicator of the buildings undergoing the analysis was the indicator of heat load demand per cubic capacity, which was established on the basis of site inspections and technical documentation. The obtained results were used in analysing the cost-effectiveness of the suggested thermomodernization works. The following were adopted as criteria of the investment effectiveness: the ‘Simple Pay Back Time’ (SPBT), reducing the amounts of particulate matter and sulphur dioxide polluting the air, and heat load saving (amounting to a few or even several megawatts, which, in the case of a small town, is often sufficient to cover a prospective increase in heat load demand).

Przedstawiono analizę techniczno-ekonomiczną prac termomodernizacyjnych budynków mieszkalnych wielorodzinnych i użyteczności publicznej wykonanych w technologii uprzemysłowionej (OWT, Cegła Żerańska) oraz technologii tradycyjnej, zrealizowanych przed 1990 rokiem. Oceniono 1441 budynków zlokalizowanych w 7 miastach. Miernikiem energochłonności budynków był wskaźnik kubaturowego zapotrzebowania na moc cieplną, który określono na podstawie wizji lokalnych i dokumentacji technicznej. Otrzymane wyniki wykorzystano do analizy opłacalności zaproponowanych prac termomodernizacyjnych. Jako kryterium opłacalności inwestycji przyjęto „Prosty Okres Zwrotu” (SPBT), redukcję zanieczyszczenia powietrza pyłami i tlenkiem siarki, zaoszczędzenie mocy cieplnej (wynoszącej kilka, a nawet kilkanaście MW, które w skali małego miasta często są wystarczające na pokrycie perspektywicznego przyrostu zapotrzebowania na moc cieplną).

The present article describes the basic legal, technical, and economic aspects of the functioning of the White Certificate Scheme in Poland. A method of performing the energy audit process (a basic element of the tender procedure) in a simplified way is presented. Essential conditions which guarantee participating in tender procedures as a necessary condition for getting bonuses for the implementation of investments resulting in reducing the primary energy consumption are also listed in this paper.

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.
