Discussion: how to choose building lighting LED lighting

Standard setting units - China Institute of building science has also begun to amend the standard advice. It is understood that the revision of the new standard from the investigation to the completion of the draft, approval, is expected to take 2 years. Such indicators will be more strict "standards should be people-oriented and create a good environment, reflects China's lighting technology level and promote the development of scientific, practical and forward-looking, and combined with the real China.

"GB50034-2004" architectural lighting design standards (hereinafter referred to as the "standard") is a construction designer design and application of lighting one of the most important standards, which includes the quantity index of architectural lighting design such as illumination, quality index, lighting power density limit, lighting power distribution and control, covering residential buildings, public buildings and industrial building lighting standards and energy efficiency standards and conducive to the implementation of the "lighting management and supervision", for the implementation of green lighting and lighting to promote the progress of science and technology and the promotion of efficient lighting products have an important role.

In recent years, with the continuous development of lighting technology in China, especially the latest generation of LED light source in indoor and outdoor growing application requirements, coupled with energy-saving emission reduction trend, for the architectural design standard has put forward new requirements. Against this background, the standard formulation of the unit - China Institute of building science has also begun to amend the standard advice.

Discussion: how to choose building lighting LED lighting

It is understood that the revision of the new standard from the investigation to the completion of the draft, approval, is expected to take 2 years. Such indicators will be more strict "standards should be people-oriented and create a good environment, reflects China's lighting technology level and promote the development of scientific, practical and forward-looking, and combined with the actual situation of Chinese to international standards, but also reflect the actual level in china. Should be advanced in technology, reasonable in economy, but also to achieve convenient maintenance, safe use, save energy, protect the environment, protect the healthy and green lighting etc.. Zhao Jianping, vice president of China Academy of Building Research Institute of building environment and energy saving. With the development of lighting technology and applications, the content of the standard also need to keep pace with the times, the revised standard will further stringent energy efficiency indicators, increase the relevant indicators of the LED application settings. LPD refers to the lighting power density, is the construction of the room or place the unit area of the lighting installation power, unit of watts / square meter. The LPD value is the main evaluation index of building energy saving, the provisions related to the LPD value, in the field of lighting energy saving and environmental protection, will promote the overall lighting design consider illumination level, lighting quality and efficiency, promote the popularization and application in the design of more efficient light source, ballast, lamps and other products.

In practical application, the LPD limit value has become an important basis for the supervision and management of lighting design, installation, operation and maintenance. A major change in GB50034-2004 standard is increased, residential, commercial, office, hotel, hospital, school and other 7 industrial buildings of 108 common room or place the LPD maximum allowable value, in addition to residential buildings, the other 6 types of building standards in the LPD limit are mandatory standards, this is also the first the history of the lighting design standard of our country. The current global energy conservation and environmental protection pressure gradually increased, LPD value is also more prominent. It is understood that the revised standards, LPD value can be adjusted greatly, make the LPD accord with the trend and requirement of energy saving, will focus on how to reduce the existing building energy saving standard room LPD, expand public building types in the provisions of the problem. It should be noted that the LPD value and the possible further reduction will be a major challenge for lighting design. For example, in the real implementation of standards, to meet the energy required LPD value and Realization of building decoration requirements often "you can't have it both ways", has become the most difficult thing for the architect.
