3 Standards of Judgment and Energy Conservation Regarding Air Conditioning Systems

3-13

(4) Measures in installing new air-conditioning facilities and hot water supply facilities
1. When installing a new air conditioning system, the following measures, etc. shall be enforced referring to the energy conservation law's air conditioning provision of the building evaluation criteria to improve the efficiency of energy use:
  (a) The system shall be of capacity that can handle change of thermal demand and shall be capable of separate control of sections to air-condition as far as possible.
  (b) Highly efficient heat source equipment that utilizes heat pump, etc. shall be adopted.
  (c) For heat source equipment and heat transfer equipment of air conditioning systems where load fluctuation is expected, systems that are capable of appropriate number separation, quantity control, and rotation speed control, and highly efficient during partial load operation or capable of high-efficiency operation such as heat storage system shall be adopted. In addition, adopting variable lifting height control shall be considered for heat transfer equipment.
  (d) When using air conditioning systems in a condition where load fluctuation is large, variable air volume or variable flow rate system with rotation speed controller etc. shall be adopted for operation control according to load.

- (e) To reduce cooling and heating load with taking in outside air during summer and winter, adopting total heat exchangers shall be considered. In addition, if cooling is required during intermediate period and winter, adopting outside air cooling control shall be considered. In this case, if humidification is performed, adoption of water humidification shall be considered.
  (f) When there is manufacturing equipment etc. that generates heat, the heat shall be directly exhausted outside the air conditioning section by using ducts or let the heat medium flow back to prevent increase of air conditioning load.
  (g) If air conditioning of the entire workplace is unnecessary, load required for air conditioning shall be reduced by local air conditioning around workers or radiant heating, etc. In addition, volume, etc. to be air-conditioned shall be minimized.
  (h) If the building have a lot of gaps or openings, close them as much as possible to reduce load required for air conditioning.
  (i) When determining where and how to install outdoor units of air conditioners, solar radiation, air flow condition, and air flow condition when they are piled up, etc. shall be considered.
