Research of thermal balance of transparent designs

Abstract

The energy independence of each state is one of the most important components of national and economic security. The country's ability to provide the economy and consumers with fuel and energy resources in sufficient quantities to ensure their efficient operation depends on this.

In its move to association with the European Union, Ukraine has made certain commitments under the Protocol of Accession of Ukraine to the Treaty establishing the Energy Community.

Implementing the provisions of the Energy Community, all EU directives and regulations on energy efficiency will enable Ukraine to benefit from the experience gained, reduce the time to develop national legislation and receive effective technical and financial support from the European Union and member states, open new sectors of the economy and create hundreds of thousands of new ones. jobs, providing consumers with better services at a lower price. A number of laws and by-laws have been adopted in Ukraine to implement Directive 2010/31 / EU.

Energy consumption of buildings largely depends on the parameters of the microclimate of premises and buildings in general. Temperature, ventilation and lighting parameters are used in design and operation. They also affect the health, productivity and comfort of the people in the room.

The calculation of the energy balance (difference between heat and heat loss) of the building is a serious tool for analyzing the energy efficiency of the building. Windows as the least protected from energy loss have great potential to increase energy efficiency. Therefore, it is advisable to study the energy balance of translucent structures of the building depending on their energy efficiency characteristics.

Determining the energy balance of a building in Ukraine is carried out in accordance with national standards. By types, the energy balance can be divided into energy (thermal) balance of the building level and at the system level. The input data for calculating the energy balance of heating, cooling and ventilation systems are energy needs for explicit heat. The calculation method in national standards is limited to heating and cooling by apparent heat. The calculation of the energy balance was performed for each window on a monthly basis and summarized within the annual heat balances.
