FEATURES MULTISTORY NEARLY ZERO ENERGY BUILDINGS (NZEB) FOR A COLD CLIMATE

Abstract

To determine the possibility of building in the climatic conditions of the city of Yekaterinburg multistory apartment houses with zero energy consumption has been selected for typical methodology (for building density, number of storeys, constructive and shape) that designates the characteristic values of specific consumption of heat, electricity and hot water to perform calculations in a typical house. Using packet PHPP (Passive House Planning Package) for a typical home computer developed two computer models: the standard design (base case)  and a house with energy-passive building technologies (improved version). The study determined that the most significant factor limiting the increase in the thermal protection of the building are energy consumption for the production of building materials, which by increasing the thickness of the insulation over the base model home magnitude of more than 500 mm, lead to an increase in energy consumption over the life cycle (including energy costs in the production of construction materials. The study proved the possibility of building a multi-storey apartment building with a zero energy consumption (as an annual balance sheet).
