LoginMore than three quarters of all consumed energy in buildings are used for heating, ventilation and sanitary hot water preparation. Energy conservation on these areas has a great potential for reduction of fossil fuels consumption and could greatly contribute to environmental assessment. In striving for reduction of energy use in buildings new criteria are enforced as a measure for energy use in buildings. Material and devices manufacturing for energy conservation by heating and ventilation and their installation and operation have the influence on the environment in the whole buildings lifetime. By energy analyses only energy flows are considered whereas by environmental assessment also influences on peoples health, ecosystem quality and resources depletion are considered. This method is known as LCA method. In the article different technologies for reduction of energy use in buildings are presented and their influence on the environment in the buildings lifetime are shown. For each analysed technology embodied energy is determined and their inventories with carried out evaluation using Eco-indicator 99 method have been made.
