Abstract:
Electricity which is the backbone of the industrial sector, plays the vital role in the development of a country. In Sri Lanka an adequate increase in the supply of electricity to meet the rising demand is unlikely to materialize, and therefore the price of electricity can be expected to rise in the future, causing a corresponding rise in the operating cost of houses. This paper explores the possibility of adopting environmentally friendly passive techniques to inhibit the thermal discomfort experienced in houses, and proposes the three storey house as the best type due to its superior thermal performance over two or single storey houses. By way of modeling of a proposed three storey passive house using DEROB-LTH simulation tool, it shows
that proper incorporation of passive features can lower the indoor temperature, in
certain cases, by as much as 6°C. It highlights the economical benefits of’the
adoption of passive concepts, both at user level and to lesser degree at national level,
and the sustainable development that results in, minimizing the degradation of the
environment
