Table A.4 - Conclusions from the assessment of the energy parameters of the building

Conclusions on compliance with regulatory requirements and documents.
If there are inconsistencies, recommendations for improving energy efficiency indicators

At the moment, the educational institution is located at: Dnipropetrovsk region ,. Dnipro, st. Stroiteley, d. 26 does not comply with applicable sanitary and hygienic regulatory acts and DBN 2.6.31 - 2016 “Thermal insulation of buildings”. At present, the institution has underheated premises by setting “limits on the consumption of thermal energy”, as a result, the energy efficiency class of the building is calculated that does not correspond to the actual microclimate conditions in the building’s premises.
However, it is assumed that modernization will improve the microclimate and the actual performance of the building.

Recommendations for improving energy efficiency:

Carry out additional floor insulation *
* The proposed event will improve the indoor indoor climate. Therefore, as a recommendation, after a complete renovation, it is necessary to modernize the ventilation system.
** Warming must be carried out in accordance with the requirements of current regulatory documents, and adhere to the technology and recommendations of manufacturers of thermal insulation materials. Integrated insulation allows you to:
significantly increase the heat transfer resistance of the external walling, as a result, when regulating the supply of thermal energy, reduce the cost of heating and air conditioning in the summer in summer, create comfortable conditions in the room; To avoid the appearance of fungus and mold; improve sound insulation of the building;
- install a decentralized ventilation system with heat recovery;
- set automatic control of the coolant in accordance with weather conditions;
- replace the heating system (replacing radiators, installing thermostatic regulators)
