By considering civil architecture region climatic differences, adopt fuzzy analytic hierarchy process mathematical method to make researches on architectural lighting relative energy saving problems. On the basis of lighting, take comprehensive consideration together with architectural energy saving factors, look for the balance point between the two. Utilize fuzzy mathematics comprehensive evaluation method, according to indicators factors, it defines evaluation system, and makes evaluation research on lighting energy saving design’s relative strategy. Conclusion thought that optimize overall architecture layout and optimize architecture form design are more important than daylight opening design. Architectural overall layout is an important method of architectural lighting and energy saving.
