Shanghai has been carrying out energy-saving in public buildings for many years. In order to achieve the goal of higher energy-saving, on the basis of the original Design Standard for Energy-saving in Public Buildings DGJ08- 107-2004, we have carefully absorbed the experience of compiling the design standard for energy-saving in public buildings in China, and repeatedly demonstrated the applicable advanced energy-saving technologies, which have been verified by calculation and solicited opinions for many times. Among them, what is the stipulation of Shanghai public building energy-saving design standard for lighting energy-saving design? The following is the introduction of the provisions of Shanghai Public Building Energy-saving Design Standard for lighting energy-saving design brought by Construction Network for reference.

The lighting power density room of Class A building shall conform to the target value specified in GB50034 of Building Lighting Design Standard, and Class B building shall conform to the target value specified in GB50034 of Building Lighting Design Standard.

Incandescent lamps shall not be used as lighting sources except in special circumstances. When incandescent lamps must be used, the power shall not exceed 100W.

Selection of light sources, lamps and accessories

High-efficiency and energy-saving light source should be selected, and electronic ballast or energy-saving inductive ballast should be used.

The efficiency of lamps and lanterns should not be lower than 0.7.

On the premise of meeting the requirements of glare limitation and light distribution, open lamps should be selected.

The power factor of lamps and lanterns should not be lower than 0.90.

Lighting control

Large banquet halls, lecture halls and hotel lobbies should be equipped with dimming controllers.

Lighting in public areas such as corridors should be controlled by time control, illuminance control, dynamic and static detection control and other control means according to the use requirements.

Hotel rooms should be equipped with key-inserted energy-saving switches.

The lamps and lanterns near the window in the large bay office should be self-contained, and the illuminance controller can be set when conditions permit.

Road lighting and landscape lighting should be equipped with automatic control devices.

Places with an area greater than 1000m2 should be controlled by district lighting, and the area of each district should not be greater than 250m2.

Natural light utilization

Indoor lighting should make full use of natural light.

When it is economical and reasonable, active light guide device or passive light guide device can be used.

When using natural light guiding device or reflecting device, electrical lighting measures should be taken at the same time.

Natural light guide devices and reflective devices shall not be used as emergency lighting.

When the natural light guide device is used, the lighting control system should be used to automatically control the electric lighting. Intelligent lighting control system can be used to control the dimming of electric lighting when conditions permit.
