Abstract: The purpose of this dissertation is to explore and understand how wasted heat originally expelled from buildings can be recovered and reused, thereby reducing the carbon footprint created. As the awareness for global warming spreads across the world, the need for more sustainable and efficient energy became apparent. In the operations of most buildings, heat is usually generated as a common by-product, of which had to be expelled from the source to prevent over-heating, which either causes inefficiency of the equipment, or the discomfort of the occupants. If some of this waste heat can be recovered, a considerable amount of primary fuel can be saved. The research aims to open up an opportunity to highlight the benefits of shifting the mindset of the industry towards sustainability, and to create awareness within the industry of the availability of such technologies. Case studies, guidelines, journals, and recent technological advancements were examined to discuss the different methods, feasibility and practicality of exploring the recycling of waste heat. Waste heat recovery has been of existence mostly in the industrial sector over the past 50 years, while less so in the commercial and residential, due to the higher temperature waste heat from the industrial sector, and the lack of technology or purpose to harvest a lower heat grade from the commercial and residential sectors. The geographic location of the buildings also plays a part in determining the methods and economic benefits of adopting heat recovery systems. Base on the case studies, the advancements in technology and rising cost of limited energy sources, the potential savings and benefits generated by the recycling of waste heat is worth noting.
