Lighting Improvement Guidelines for Luminance Uniformity Form Case study; Cultural Market of Phra That Community Na Dun District, Maha Sarakham
This research aims to study about Cultural market building, Phra that, District of Nadoon, Mahasarakam where has been renovating in order to calculate the lightening within building and examine that those controls has compromised with Market building standard, or not. The study has built the simulations of building in Dailux 7.9 program. As a consequences of 3 days (21 March, 22 of June and 22 of December) experiment which was studied three times a day, 9.00 am, 1.00 pm and 4.00 pm. The studied indicate that the lighting in this building, is about 500 lux higher than referred standard. The study has recommended the solutions as installing Shading Device for protection of dazzle by these three following types which are (1) horizontal Shading Device (2) vertical Shading Device (3) mix -horizontal and vertical- Shading Device. After installing these three Shading Device, the research results demonstrate that the lightning has still been higher than standard controls. However, mix Shading Device has been controlled the lightening, better than vertical or horizontal Shading Device. Moreover, as a result of open air building, it has no walls covering all 4 sides which the lighting could dazzle, easily. To install Shading Device protection, it is just preliminary solutions for better lightening controls.
