2-2 Air-conditioning and water-heating facilities

(1) Management of air-conditioning and water-heating facilities
1. Air conditioning shall be implemented by determining air-conditioning zones and implementing management standards on operating time, room temperature, ventilation frequency, humidity, etc., and operating status depending on load reduction due to blind control, etc. based on the predetermined temperatures recommended by the government.
2. Heat sources of air-conditioning equipment shall be managed by implementing management standards to maximize overall energy efficiency of equipment including auxiliary equipment such as heat sources and pumps, cooling towers, etc., based on atmospheric conditions such as seasonal changes, etc.
3. If air-conditioning equipment consists of multiple heat sources of the same type or comprises heat sources using different types of energy, management standards shall be implemented to maximize the overall energy efficiency of heat sources by adjusting the number of units in operation or by selecting units for use based on atmospheric conditions such as seasonal changes, etc.
4. If air-conditioning equipment consists of multiple air-conditioning facilities of the same or different type in the same air-conditioning zone, the number of facilities in operation shall be adjusted based on the load condition based on management standards implemented to improve overall energy efficiency of air-conditioning facilities.
5. Water-heating facilities shall be controlled by limiting feeding destinations based on season and work content, and management standards shall be implemented for improving water-heating temperature, water-heating pressure, and water-heating efficiency.
6. Heat source equipment for water-heating facilities shall be controlled by implementing management standards based on load fluctuation to improve the overall energy efficiency of equipment including such auxiliary equipment as heat sources, pumps, etc.
7. If heat source equipment consists of multiple heat sources, management standards shall be implemented to improve the overall energy efficiency of equipment by adjusting the number of units in operation based on the load condition.

(2) Measurement and recording of matters for air-conditioning and hot water supply facilities
1. Management standards shall be implemented for measuring and recording temperature, humidity, etc., required to determine the state of air and improve air-conditioning efficiency in each air conditioning zone, and such matters shall be regularly measured and results recorded based on standards.
2. For heat sources, air-conditioning equipment, pumps, fans, and other components of air-conditioning facilities, management standards shall be implemented for measuring and recording matters required to optimize the efficiency of individual equipment and overall efficiency of air-conditioning systems, and such matters shall be regularly measured and results recorded based on standards.
3. For water-heating facilities, management standards shall be implemented for the amount of hot water supplied, hot water temperature, etc., required to optimize the efficiency of supply of hot water, and such matters shall be regularly measured and results recorded based on standards.

(3) Maintenance and inspection of air-conditioning and water-heating facilities
1. For heat sources, air-conditioning equipment, pumps, fans, piping, ducts, and other components of air-conditioning facilities, management standards shall be implemented for the maintenance and inspection of matters required for optimizing the efficiency of individual equipment and the overall efficiency of air-conditioning facilities as a whole, such as clogging of filters and removal of scale adhering to capacitors, and regular maintenance and inspection of such matters shall be conducted based on standards to maintain facilities in good condition.
2. For water-heating facilities, management standards shall be implemented for the maintenance and inspection of matters required for optimizing the efficiency of supply of hot water, such as the removal of scale adhering to heat exchangers, and regular maintenance and inspection shall be conducted based on standards to maintain facilities in good condition.
3. Management standards shall be implemented for the maintenance and inspection of matters required to management of automatic control of air-conditioning facilities, and regular maintenance and inspection shall be conducted based on standards to maintain facilities in good condition.
