Economic and Energy Use Intensity Evaluation of Renewable Heating and Cooling Systems for A Sample Residential Building in Kirkuk

Energy consumption and CO2 emissions in the world are increasing day by day. One of the biggest reasons for this increase is traditional buildings. A large portion of the electricity needed by buildings is produced from fossil resources, and as a result, CO2 emissions increase. The concept of a nearly zero-emission building has emerged to meet this need. In the analyses conducted for a sample building in Kirkuk, Iraq, where different strategies, primarily the integration of renewable energy systems into buildings, are applied, it has been determined that the sample building's annual energy consumption intensity is reduced by approximately 65% with different strategies, while providing approximately 68% annual economic savings.
