Life Cycle Assessment and Economic Energy Efficiency of a Solar Thermal Installation in a Family House

Designing solar strategies is a powerful step forward to set up an adequate residential house in terms of energy. Many types research have simulated the energy needs for buildings. improper installation can contribute growth overall expenditure ensuring thermal comfort. The use processes Slovakia on rise as compared recent years. This study models twelve water heating systems created roof household. Solar techniques are carried out comply with demands and domestic hot water. analysis deals most efficient alternative arranged building. Considering these installations corresponding prices machinery, best workable selected. potential performance auxiliary output examined. required amounts different contributions modelled specific software family Kosice, Slovakia. We determine limits design apartment analyse which procedure used provide typical average need, covering multi-criteria considering costs, energy, life cycle every installation. approach support professionals decide scheme criteria, this method be satisfactorily applied. In conditions, converting conventional gas boiler into system involves monthly economic savings around EUR 140–250, payback periods 2.5–7 requirements fully covered by schemes assessment resulted reasonable impacts environment.
