As traditional energy sources such as fossil fuels become increasingly scarce and the energy demands from many modern buildings are regularly scrutinised. Building designers and engineers are now relying more on alternative energy resources, with the application of renewable energy and low carbon systems been increasingly common in the discipline of building engineering.
The aim of this module is to give the student a detailed knowledge and understanding of various renewable energy and low carbon technologies applicable to buildings. It’s structured to provide the student the ethical and technical knowledge to enable for the optimal design and application of various renewable energy and low carbon technologies which are applicable in the discipline of building engineering.
