Abstract

A genericatrium building was designed to incorporate low energy solutions and features of both vernac-ular and contemporaly South Asian architecture. To achieve low energy and comfort within the atrium srepparcees,e snotmateiv kee cya dreessi.gTnh ivsa DriTaMbl ems owdeerl ew eaxsa dmeivneeldo pbeyd rwuintnhi mngual tdipylnea lmeviecl sth aenrdm zaoln meso tdoe sl i(mDuTlMate) f othre s ohmeaet and air movement throughout the building and validated with the data measured in a real building of similar form. The modelling study was carried out to investigate the effects of N o roof farms for the atrium and three low cost ventilation solutions on indoor thermal comfort. It reveals that low cost ventilation and acceptable comfolt are achievable in this traditional form of architecture and low energy solutions and careful design can complement well its Functional aspects and even enhance its aesthetic and practical qualities. The solar heat gain, air temperature, and mean radiant temperature in the atrium were used to assess the effectiveness of clerestory windows with opaque rooftop (i.e. side-lit model] as compared to the fully transparent glared rooftop (i.e, top-lit model). Data on cooling loads, indoor air temperature, and mean radiant temperature were used to evaluate the design options with special consideration on local adaptable thermal comfort criteria. The possible effects of the research outcomes on the incorporation of atria are discussed at the end.
