| Summary: | A generic atrium building was designed to incorporate low energy solutions and features of both vernac�ular and contemporary South Asian architecture. To achieve low energy and comfort within the atrium
space, some key design variables were examined by running a dynamic thermal model (DTM) for some
representative cases. This DTM model was developed with multiple levels and zones to simulate the heat
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 two roof forms for the
atrium and three low cost ventilation solutions on indoor thermal comfort. It reveals that low cost ven�tilation and acceptable comfort 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 glazed 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. |
