Opis:: In October 2014 in a building of Rzeszow University of Technology, a series of measurements was taken to calculate the parameters of a solar system with a flat collector, as installed on the roof of the building. The following parameters were obtained: the value of solar radiation intensity, the temperature of external air, the temperature on the collector, the temperature of water in the tank and the temperature of glycol on the supply and return lines. On the basis of the data received, charts were made to visually present how changes of solar radiation intensity affected parameters of the system. The study was conducted in autumn when the intensity of solar radiation decreases, compared with summer months. The publication aims to show that the solar system brings energy gains in periods of transition, and the instantaneous intensity of solar radiation are comparable to those in the summer.

Opis:: A lot of attention is nowadays devoted to the problem of generally defined ecology. It is absolutely essential in case of systems and sources generating heat due to their direct influence on the environment through emitting post-process products to the atmosphere which are, most frequently a result of combustion. Therefore, constant searchers are made to optimize the operation of heat sources and to acquire energy from sources for which the general balance of carbon dioxide emission is zero or close to zero. This work compares the emissions of equivalent CO₂ from selected systems with the following heat sources: coal, gas furnace, heat pump, and refers results of the analysis to aspects connected with regulations concerning environmental protection. The systems generating thermal energy in the gas furnaces, coal, biomass, as well as the compression heat pumps with the lower heat source as ambient air or ground were taken under consideration, as well as centralized systems for the production of heat based on the combustion of coal, gas, oil, and biomass. the Emission of carbon dioxide for the installation of cogeneration and absorption heat pump were also calculated. Similarly obtained amount of extra emission necessary for the proper operation maintenance of heating devices via the supplied electricity from external source, the mostly fuel-fired power plants for fuels as previously mentioned. The results of the calculations were presented in tables and graphs.

Opis:: Ventilation systems consume more and more energy because of the often complex treatment of the air supplied to closed spaces. Looking for sources of energy allow for significant savings costs, which often translate into renewable energy sources. One of the more popular solutions is to use energy from the ground by various methods. Known and relatively common solutions are based on ground heat exchanger and ground collector cooperating with a heat pump. The paper presents the possibility of cooperation ventilation system with ground air heat exchanger and heat pump both in summer and winter period. A number solutions of this type of system, supported by calculation examples and moist air transformation in the Moliere chart have been presented. Support ventilation system with renewable energy sources allows significant savings in operating as shown in the article.

Opis:: Thermal insulation materials and technologies for thermal insulation of houses were investigated. The widespread use of such materials is due to the saving of fuel and energy resources, in particular, during the operation of buildings and structures. The subject of the analyzed stage of the research is the use of modern thermal insulation materials in construction, comparative characteristics of materials and processes associated with thermal insulation technologies. A list in the form of a table of the most used on the Ukrainian thermal insulation materials with comparative characteristics was considered. The most optimal from the point of view of ecology are ecowool, foam glass and mineral wool. The disadvantages of materials are the high cost of work and installation. Polyurethane foam, relative to other heat-insulating materials, has a minimum thermal conductivity. Also, along with glass wool, it is an excellent sound insulating material. The main requirements for thermal insulation materials are fire resistance. All listed materials correspond to this characteristic, except for expanded polystyrene. The construction industry in Ukraine is dependent on the country's economic factors. Back in 2015, there was a sharp decline in the market volume associated with an unstable political and economic situation. However, a year later, the pace of construction work has noticeably accelerated by 13,1%. This is due to the growth of the real estate market, the level of purchasing power, the popularization of energy-efficient construction in the country, and, therefore, the latest technologies and innovations in the direction of energy-saving materials.
