OPTIMISATION OF DAYLIGHTING AND MINIMISATION OF HEAT GAIN IN SELF SHADING OFFICE BUILDING IN MALAYSIA



ABSTRACT
Heat gain due to solar radiation to wall is contributing into high energy demand for building systems especially for office buildings in tropical regions such as Malaysia. Self-shading buildings can avoid heat gain while allowing daylight to penetrate the buildings. In this research the effect of self-shading strategy on heat gain and daylight penetration was investigated. The ultimate aim is to find the best angle with the least possible level of heat gain during working hours and minimum window area on an inclined wall in order to achieve the minimum acceptable daylight penetration. The Energy Commission s Diamond Building in Putrajaya was chosen as the case study of an actual self-shading building in terms of heat gain and daylight penetration. The amount of Overall Thermal Transfer Value reduction was calculated in the building using analytical methods. Extensive simulation models were carried out using Integrated Environmental Solution software and the results were compared to the empirical findings in the field for validation. The findings demonstrate significant effects of self-shading on the amount of heat gain and daylight factor. Ceiling projection to wall height ratio (SSP Ratio) has reverse correlations with the amount of daylight penetration. Simulation results show minimum heat gain can be achieved when SSP Ratio is 50% regardless of Window to Wall Ratio (WWR) values. However in order to provide optimum daylight, 70% WWR is required. Findings of this research can be employed as one of energy efficient office design strategies for tropical office buildings.

DOUBLE SKIN FACADE OFFICE BUILDING



Abstract
Building aesthetic, thermal and noise reductions as well as wind protection are the main reasons to use Double Skin Facade (DSF) in modern high rise office buildings. Previous researchers have suggested that the risk of overheating within (DSF) envelope is high in tropical climate. However, some recent studies (Hien, 2004 and Wong P.C., 2008) have proved that DSF improve thermal comfort in highrise building in the tropics. This research aims to analyse the effect of DSF glazing material, DSF cavity depth and combination of DSF together with thermal wall strategies on lowering solar heat gains in DSF office building in tropical climate of Malaysia. The study has been carried out by simulations and mathematical model. The simulation process contains two parts. First,  Airpak software simulation as a pilot test and aims to evaluate DSF configurations in different orientations and different solar times. Second, whole building simulation by both Airpak and Flovent softwares. The whole building simulation focuses on investigating the effect of different DSF configurations in particular solar time and building orientation.  Results of this study found that DSF is not able to reduce solar gains in West and East orientations.  On average, 11% of reduction in rooms temperature was obtained in both South and North orientations, as compared to Single Skin Façade (SSF). This amount is equivalent to 3°C reduction in indoor rooms temperature. The optimum reduction of heat gains was found in the case of DSF with air-gap size of 1.0 m comparing to those with air-gap sizes of more or less than 1.0 m. This study also found that reflective glazing is the most effective material of which it is able to reduce room temperature by 2°C on average. Lastly, different configurations of thermal wall are tested, however, the results do not show significant improvement in DSF performance.

DAYLIGHTING IN ALGERIAN CLASS ROOM

Daylight quality and quantity in Algeria schools shows an urgent condition to ensure visual comfort for students and teachers. Some problems arise due to poor window design and excessive amounts of daylight penetration inside the classrooms as well as non-uniform daylight, which may cause glare and heat gain. This study aimed at choosing an ideal window size and glazing pattern to maximize daylight effectiveness and occupant comfort in Algerian schools. Field measurements of selected classroom were carried out in selected school in Algeria during summer and winter season. The data were analysed and used to develop model design for simulation. Seven patterns of glazing windows design were used for extensive simulation exercise. The results of the investigation from the site measurements show that WWR was more than 40%; the WPI was found to be within the range of 300lux to 500lux and the DF of 4%, which exceed reference value except the southeast orientation 2.98% in morning and 2.29% in the evening. Result from simulation using IES by comparing three different glazing types (tint, clear and reflective) and using different  glazing size from 25% to 75% in winter season (under overcast sky condition) and summer season (under intermediate sky condition). The evidence from this study suggests that tinted windows in both winter and summer is ideal as the simulations result shows that significant usable area of (31.22% - 41.74%) is achievable in a bilateral window opening with a (DF<2 25="" 300lux="" 30="" 500lux.="" 50="" 75="" a="" adequate="" algeria="" and="" as="" be="" bilateral="" by="" configurations="" daylight="" daylighting.="" design="" different="" during="" enhancement="" experiment="" for="" from="" further="" glass="" glazing="" has="" ideal="" impact="" improve="" in="" increasing="" it="" louvers="" need="" of="" overhangs.="" percentage="" public="" quality="" quantity="" range="" research="" result="" school="" schools="" shelves="" significant="" span="" steaming="" suggest="" that="" the="" tinted="" to="" unobtainable="" use="" variations="" vt="" was="" with="" within="" would="" wpi="" wwr="" yield="">
