Renewable and Integrated Energy Supply for Sustainable Urban Housing
A major part of the energy consumption in a building is due to heating and cooling. Therefore there are many economic and environmental gains in optimising the energy supply.
Several technologies have been developed in recent years to lower energy demand and the ensuing environmental impact from power generation. Either by switching to renewable fuel sources such as residues from forest- and agricultural activities, or by reaching higher and higher efficiencies in the power generators.
District or central heating is a feasible way to design a specific heating or cooling system that utilise large-scale advantages. Combined Heat and Power (CHP) utilise the heat from the power generation to heating space and hot water. Condensing gas boilers use a similar concept. By incorporating an extra heat exchanger the hot exhaust gases transmit much of their energy to pre-heat the water in the boiler system.
Buildings are often large systems with numerous energy streams of air and water, and hence it is highly feasible to optimise the energy fluxes by considering integrated ventilation - and Energy Management System (EMS).
