Scientists predict that emissions of CO2 and other greenhouse gases from human activities will raise global temperatures by 2.5ºF to 10ºF this century. The effects will be the threat of climate change. To address, greenhouse gas emissions must be stopped, and reversed. Energy efficient buildings is one of the best strategies for reductions in energy and CO2 emissions and meeting the challenge of climate change. Architectural strategies can reduce CO2 emissions while improving the bottom line through energy and other savings for buildings. The aim of this paper is to describe and analyze architectural strategies for reductions in energy and CO2 emissions such as site planning and building configuration , Locations include being near public transport ,landscaping, orientation for good access to sunlight and daylight, Direct and indirect solar gain, Building form and envelope. Locating functions can enhance energy efficiency and reduce CO2 emission. Cross ventilation is best way of Natural Ventilation of buildings in areas and also Good day lighting reduces energy consumption. Design features encouraging recyclinghelp divert waste from over-burdened landfills and save virgin materials.
