Abstract:
In today's buildings most of the total primary energy consumed is used for heating, ventilation and air conditioning. Conventional heating and cooling systems have a fairly large impact on operating costs, energy requirements and carbon dioxide emissions.
In this paper we have calculated the heat demand for heating the house in the winter months. For this we estimated the amount of heat loss through the envelope of house, the heat input from the solar radiation input, heat loss related to the production, distribution, heat release and adjustment of the heating system, energy input to the system, including energy recovered. An excel application was created in order to compute all these values for different geographical area in Romania and different types of house envelope.
Going from the results of energy demand in a traditional house, we also simulated an improvement of the insulation of the exterior walls by applying a layer of 15 cm thick wool as insulating material on the inside. For the study house a 10% reduction of energy consumption was obtained and also a 10% reduction of CO2 emissions.
