Providing the population with affordable and high-quality housing that corresponds to the principles of the modern world policy of sustainable development is an important strategic social task that is relevant forUkraine. For successful solution of this task it is necessary to introduce into mass construction the energy-efficient economically substantiated techniques of the use of ecological materials in the design of low-rise residential buildings. For the housing construction ofUkrainein the conditions of the national ecological, economic and social crisis it is a very urgent issue of reducing the use of energy resources in the operation of housing, the development of new environmental energy-efficient technologies of new construction, the creation of alternative and quality affordable housing. Today solar energy is one of the most promising areas in the field of alternative energy. Houses of zero consumption are practical and they are already moving from the future to the present. Everything depends on the owner's desire to live in harmony with nature, and then the designers, builders and installers will do everything to make the building known as zero consumption. In modern design engineering systems, instead of traditional radiators, more energy-efficient design solutions are increasingly used. One of these is the use of a warm floor for the heating of low-rise buildings. The heating with warm floors has a lot of advantages compared with other types of heating: saving free space, saving resources, lack of drafts, a healthy climate in the house. In addition, water systems are integrated into heating, which uses the alternative sources of energy: heat pumps, solar panels, condensing boilers. One of the components of this work is the design of the house and calculations of cost-effectiveness.
