Towards modern options of energy conservation in buildings
2017
Looking at modern options of energy conservation in buildings it is necessary to assure energy efficiency first. When the energy load of a building is highly decreased, then innovative options of energy conservation can be introduced. The background and development of the main modern methods for the reduction of energy needs, final and primary energy consumption are analyzed. Differentiation between options for existing and newly constructed buildings is pointed out. Modern options of energy conservation in buildings are focused on innovative architecture, shape, structure, materials of a building and of course systems utilizing renewable energy. A very simple way of reducing building energy needs is the utilization of solar energy in a passive, but planned way. A specific shape of solar buffer space should be created in the building. In high latitude countries the buffer space should be of a specific design containing two cuboid sub-spaces with specific internal overhang and a well-planned extension of the south glazed facade. The paper presents modern renewable energy technologies as technologies with roots in past ideas of using the environment in an effective way. It underlines that future innovative and efficient building technologies will use building integrated renewable, mainly solar technologies.
