Current building regulations enforce building designers towards efficient system design and provision of alternative means of supplying energy. Different green building certification schemes are deployed worldwide to encourage creating a sustainable built environment and the adoption of green building best practices.

Micro-generation technologies, low and zero carbon, are either recommended by designers or mandated. A range of constraints including design and technical issues, are currently affecting the wide-scale deployment of micro-generation. For instance, it is important that the micro-generation plant operates for as many hours as possible as an idle plant accrues no benefits. Such issues make the design of a micro-cogeneration technology not quite as straightforward. Combined Heat and Power (CHP) or micro-cogeneration provides means of electricity and heat supply.
