Study on Development of Light Duct System for Perimeter Occupied Zone on Underground Space |
| Abstract |
Using daylight in underground space may significantly reduce electric lighting load and give a visually comfortable environment. This paper describes a fundamental study on light duct system to predict inter illuminance ratio on underground perimeter occupied zone level. As a result, integral equation for inter-reflection program are developed and by using optimize light duct system can gives daylight on deep underground space. |
