Energy is one of the greatest suits usa needs of society, in the past, today and especially in the future. Energy consumption is an integral part of everyday life of the individual and the industry. The need for energy as electric suits usa and heat is growing both locally and worldwide. suits usa The current production of energy based on the use of fossil fuels (coal, oil, natural gas) and nuclear energy, which despite emissions of carbon dioxide, which is one of the causes of global warming, dumped radioactive material - nuclear waste plants that pollute the environment. Today's society is striving to energy consumption to minimize or to start using renewable energy once more, but worthwhile venture. For this purpose, use solar panels, windmills, geothermal energy - heat or the country, etc. The following are the general characteristics of solar radiation and biomass as an energy source, and their utilization to meet the needs of STV and heat for heating.
Macedonia is an area where, suits usa according to previous measurements, the intensity of solar radiation is beneficial for obtaining energy from the sun. Global solar radiation R. Macedonia is the most mountainous region in the southwest and its maximum annual value is about 1500 kWh / m second The total annual global solar radiation for Skopje (north latitude 41 0 59 'east longitude 21 0 28' and an altitude of 240 m) is 1367 kW / m 2, which is one of the smallest values in R. Macedonia. Using the available hourly values of global and diffuse solar radiation on inclined surface, using the model of Perez, the value of the angle of inclination to Skopje from 45 0 C at azimuth 0 0 C, the average annual global solar radiation for Skopje suits usa is 147 3 kWh / m 2 [1].
It is estimated suits usa that the solar radiation in the country, the use of solar panels with a total area of 0.1% of the area of the Republic of Macedonia, can get an average annual 35 TWh heat (for global solar radiation of 650 W / m 2 and duration of 2100 hours per year).
Coefficients of utilization of 10%, can build solar power plants with a total installed capacity of 1670 MWe, which on average per year (2100 hours) will produce 3,5 TWh electricity [2].
The pellets as fuel is a renewable source suits usa of energy, with clean burning and sweeping the lowest price compared to all other energy sources. The pellets are biomass product made from renewable substances, mainly from recycled suits usa wood. The quality of the pellets depends on the raw material from which they are made, the way of pressing and humidity of the raw material.
The energy value of biomass is determined by its chemical composition and is measured as the energy in Joules 1g fuel (J / g) (in practice usually expressed as MJ / kg or GJ / t). Also for practical purposes as an important parameter is the volume indicator for fuel expressed through energy density [3].
The first phase of the research is to determine the total need for heating of individual residential buildings with an area of 170 m 2nd Using the equations for calculating the toplinopreminuvanje through walls [1] and the equation for heat losses [2] [4], the total presmet
