Abstract

Three models of greenhouse, an internal-movable 50% shade screen mounted directly above the floor, a double envelope roof that was elevated 0.6 m from the ceiling, and an internal-movable shade screen with a double envelope roof were compared with the greenhouse designed with a modified arch roof type with a length of 6 m, width of 3 m, gutter and gable heights of 2.4 m and 0.6 m, respectively. The greenhouse located in Kuala Lumpur (latitude =3.12° and longitude = -101.60°). The calculations were performed using the building energy analysis program (DOE-2.1E). The comparison was made based on the reduction in thermal gains and cooling load. The results showed that the internal, movable 50% shade screen was found to be the most effective in reducing maximum cooling load requirement (at 14.89%); the double envelope roof models with and without shading reduced maximum cooling load by 10.11 % and 9.39 %, respectively.
