There are lot of factors in day to day life which effect the environment because of human activities at local and global scale. But among all, construction plays a very important role in damaging the environment right from site clearing, transporting material, construction process to operating the building and recycling it after a period of time. Today along with social and economic issues of urbanisation, the environmental issue also needs a sensitive attention to work on. In rapidly developing countries,economic growth in industrial cities plays a significant role in construction and concentrating population. Industries and energy use in constructions contribute to overall degradation of environment and in raising pollution levels. The cities like Ludhiana are expanding its ecological footprints through carbon dioxide emissions, urbanisation, consumption of land and other human activities and accommodating forests, agriculture, water and other surfaces beyond the city limits. The cities are facing enormous environmental impacts because of rapid construction activities and rapid growth of residential buildings. There is a difference in developing countries and developed countries. In developed countries, the environment is the main consideration as the countries are developed economically, but in developing countries like India, the economic and environmental issues should be taken parallel. Environmental problems of modern citiesare: pollution through industrial and construction wastes, water supply and waste, solid waste, air pollution, traffic etc. These problems are mainly in developing countries which are going through economic transition. The underlying causes of leaving the environmental impacts are production of consumption of energy in cooling buildings, industries, traffic etc. But in this paper we are focussing on how the passive construction techniques in cooling building can contribute in protecting the environment and how these techniques can help in improving the environment of Ludhiana which is presentlyone of the fastestcities of India in construction industry if promoted by the city architects.Buildings usually consume about forty percent of the total energy production in world, which results in producing about forty percent of the nitrogen oxidesandsulphur dioxide thatresults in causing acid rain and contribute in forming smog. Thus this whole process according to the institute of world watchis contributing to the climate changes and leads toaccumulatingthetrapped heat gas. Energies used in buildings also contribute inthirty three percent of all annual carbon dioxide emissions
