Сhanging Energy and Exergy Comfort Level after School Thermomodernization

Buyak Nadia, Deshko Valeriy, Bilous Inna

Increasing the level of thermal resistance of the building envelope in combination with the choice of heat source is an urgent task. It is important to take into account changes in the cost of energy over time. Thermal modernization, in its turn, allows to increase the level of thermal comfort, which is not taken into account and evaluated in practice, although the relevant standards for comfort conditions and categories of buildings to ensure comfort have been introduced in Ukraine. This paper analyzes the change in the level of comfort after thermal modernization, determines the category of the building to provide comfortable conditions, as well as identifies the change in the average radiation temperature of the fences, as one of the main factors of PMV change in these conditions.

Dynamic modeling of energy need for heating and thermal comfort dependence on building envelope characteristics

Deshko Valeriy, Buyak Nadia, Bilous Inna

Journal of New Technologies in Environmental Science

2019

Vol. 3, nr 1

10--19

The analysis based on dynamic modeling of the parameters changing effect of the building envelope on the thermal state has been carried out. The influence on the building energy need for heating of the mass building thermal inertia features for various thermal resistances and the different glazing area under the condition of constant room air temperature was investigated. The influence of changes in environmental parameters during the heating period on the parameters of thermal comfort and on average radiant and operating temperature for various variants of building envelope, glazing area of the windows and massiveness of envelope has been also investigated.
