Unlike flat roofs, building walls are not only orientation sensitive but also one of the most important building element for heat gain. Also, orientation is one of the most basic but most effective technique of passive solar design. Although many passive design techniques may not be suitable in present times but orientation considerations are still relevant and can protect a building from a good amount of solar loading and thus provide ample opportunities of energy conservation in buildings. Delhi-NCR is among the areas which are observing maximum growth at present in India. If this development is based on suitable energy conservation techniques like orientation, it would be great service not only to building industry but also to the nation and environment. It could be easily achieved by avoiding worst orientation at design stage itself. Hence orientation of buildings at DELHI-NCR for maximum solar heat gain in summer has been obtained through simulation technique. Sol-air temperature, azimuth angle, solar flux and various other parameters involved have been found out at each day of every months of the year at a time interval of 15 minutes. Subsequently, mean maximum sol-air temperature and corresponding solar azimuth/orientation for each month has been obtained which can be utilized to make the building energy efficient. Although nowadays several simulation software are readily available for energy analysis of a whole building designed without pre-consideration of orientation but if an architect consciously designs a building, avoiding wall surfaces from facing worst orientation, it would further make it very energy efficient by reducing sufficient amount of heat gain.
