Methods of energy conservation (ALL)
In new buildings, many energy-saving methods are adopted such as "Reduction of load" for building and "Energy Conservation Control", "Heat recovery", "Reduction of power for conveyance of heat" and "Energy-saving heat source equipment" for facilities. Besides, Softening method, resource saving, lighting, EV and load of electricity are also considered for adoption.
In renovated buildings, the adoption rate of methods is lower than new buildings because many of the methods are restricted.However, "Mechanical method" and "Energy conservation of lighting" are more adopted comparing to other energy-saving methods. Also, replacement to high-efficiency transformer and improvement of control system can reduce a loss of the transformer, these methods can be adopted easily for renovated buildings.
