Based on the current indoor environment problems of solar buildings, how to optimize indoor thermal environment, improve indoor lighting quality, and improve indoor air quality under the premise of energy saving. In areas with high solar radiation intensity and high natural illuminance level, strong solar radiation will cause uncomfortable glare in south-facing rooms, resulting in uneven spatial illuminance distribution and poor lighting uniformity within the field of view. In order to alleviate the uncomfortable indoor light environment, when people work and study during the day, they often draw curtains to block the entry of natural light, and use artificial lighting to meet the indoor illumination requirements, which not only results in waste of additional lighting energy consumption, but also Great loss of solar radiation heat. When the external environment of the building is unfavorable, such as the heating season, most indoor users will choose to close the doors and windows to block the direct effect of the unfavorable outdoor climate on the indoor space. If the fresh air system is not used, this operation will also cause poor indoor ventilation. , lack of fresh air, affecting indoor air quality. Especially in buildings with high lighting quality requirements and high personnel density, such as teaching and office, such problems are more prominent.
