Perhaps on one hand Pakistan is facing severe energy crises, and on the other the planet earth is going through global warming. The only solution is low carbon planning. The purpose of this paper is to show the benefit of low energy residential designs. It is normally believed that closely controlled conditions equate with better comfort. Analysis of field surveys and adaptive comfort theories have made it clear that while closely controlled is one way of achieving comfort it is not the only way. This paper has taken into account analysis of an Eco-House designed by the author, this design considers energy efficiency in terms of passive methods; hence here is a comparative study of two types of houses. Primarily, there is a complete analysis of an existing house in UET (University of Engineering and Technology, Lahore) staff colony that adopts conventional methods of achieving comfort through energy consumption. The latter house is an Eco-House design proposal for which creative design strategies are discussed in detail. The results obtained provide us the substance to statistically show the benefits of low energy designs. The findings also highlights the importance by providing an insight details for the architects to understand the interesting elements in designing and detailing a low energy building.
