Underground Passage

In response to the concept of Olympics, Beijing Olympic buildings use solar light pipe systems for daylighting, such as the underground passage in the Olympic Forest Park and the gymnasium of University of Science and Technology Beijing. In this paper, the solar light pipe systems in the two buildings have been measured to find out whether indoor daylighting performance can meet daily use requirements. At last, compare the result with T8 fluorescent lamps to get the energy saving effect of two buildings. Calculating results showed that indoor illuminance of the two buildings can achieve daily use requirements when external illuminance reaches 25036lx and17895lx, and the amount of electricity that can be saved are 2514KW•h and 22186KW•h per year.

In the paper, the hybrid of daylight and artificial light is designed in the lighting of an underground tunnel in order to achieve the effect of energy saving and emission reduction. Light pipe and LED lamps are arranged in the lighting of the underpass. The software of DIAlux and Skyvision are used to simulate for the average luminance, average illuminance and energy-saving index parameters. The energy-saving effect of hybrid lighting system with natural light and LEDs is analyzed.

Reflective Coatings

In this article, we mixed hollow glass beads with nano-TiO2 and iron oxide red in a certain proportion to prepare a low-brightness, high-reflective, safe, and durable cooling coating throughout the experiments. The coating is suitable for energy-saving in tropical areas. To discuss the energy saving effects of the coating on an exterior envelope in tropical areas, a comparative analysis for two scenario models of a two-story residential building in Kuala Lumpur, Malaysia was conducted. The results indicated that the heat reflective insulation coating could reduce the exterior envelope surface temperature effectively, and the maximum temperature change was about 6–8 °C. Through calculations, it was found that the annual energy saving rate was 12.9%, which showed that the energy saving effect of the heat insulation coating was obvious in Kuala Lumpur. The brightness of the coating was less than 50%, and its comfort and safety met the requirements.
