The temperature, availability and timing of any given thermal energy source varies at each location. Their suitability to a given building will be determined by the method used to access that energy and the cost of doing so.
Importantly, Note 1 in the above table is critical with respect to the renewable definition. A poor design or application can quickly result in a seemingly renewable source becoming a non-renewable system.
Renewable thermal energy systems are multidisciplinary by nature. Successful implementation of a system requires the coordination of architects, engineers (mechanical, electrical, environmental), hydrogeologists, geologists, drilling and earthworks contractors, plumbers, electricians and refrigeration technicians as well as the builder, client, project managers and others.
