ABSTRACT:
The economical strategy of sustainable development imposes the promotion of efficiency and the rational use of thermal energy in buildings, the major energy consumer, globally speaking.
To reach the objectives of sustainable development’s principles, the heat flux demand was parameterized to reduce the energetic consumption and implicitly to heating costs, having in view the minimization of heat loses through thermal transfer with the environment, ensuring in the same time the necessary heat comfort. With this end in view I compiled a calculus model to point out the importance of effects that parameters involved in thermal energy demand calculus for heating a building. The model was transposed into a client-server application available on-line. The implementation was made with the scripting program PHP (pre-processed hypertext language), displaying the results into a HTML interface.
The calculus model and the obtained results are presented in order to discuss about the influences that constructive parameters have on heat flux requirements with the object of renewable energy heating system use.
The most common heating system that utilize renewable energy sources are heat pumps, solar energy collectors and solid fuel combustion system.
The first part of the project represents some generalities about building types, placement and renewable energy sources available at the moment for heating the existing house model and the water.
The software for heat flux demand calculus is presented in the second part of the paper, along with the conditions that inertial elements have to accomplish for the associated parameters to aim the necessary values of an energetic passive house.
The third part presents the existing system types on the market and the calculus for choosing the best fit system function to heat flux requirements and house dimensions.
The last part of the paper it consist of graphic presentation of the chosen system.
All of the dates along with the house model designed in Solid Works software are available on a CD attached to this thesis.
