Abstract
Buildings show its features by sunlight, and because of economic development and high living level, so city development and new buildings will consider its nightscapes one after another. Due to improperly building facade lighting at night time that cause of increasing lighting power and light pollution. So there have lighting power density standard and light pollution protection code in other countries, but we do not have any relative standard to obey.
This study investigated 18 existing buildings facade lighting at night time by measuring its facade and surrounding environment luminance, then get 8 cases of building facade lighting power density, then to hold a meeting that invite experts to get opinions who are come from industry, government, university, then completed the building facade lighting guideline.
The content of guideline include some code of the energy saving for building facade lighting and light pollution protection at night time,and set the appearance of the building with the concept of energy saving lighting power density to trial checklist for related units based on architectural lighting design.

This research, by analyzing and comparing with other countries’ present standards, includes building facade lighting design of energy-saving, light pollution and to prevent the criteria for future urban design consideration and the relevant agencies for architectural lighting design and acceptance of the basis .

Proposed building facade power density values can be incorporated into the daily green building energy efficiency indicators, in order to achieve lighting energy-saving and light pollution prevention .
