Within a city there is a broad spectrum of functions, each of which has its own energy signature. By smartly combining different functions, we can reduce energy usage. This
densification in energy use creates a closed, self-sustaining system. The proposed scheme has three steps:
First the energy demand for the individual functions is reduced by applying the latest techniques in isolation and smart building design. Secondly the energy demands are combined and waste energy is reused or stored. Thirdly, sustainable energy production techniques are used to fullfil the remaining energy demand.
The exchange of residual heat and cold is at the heart of the scheme. Using the waste energy of one function, to heat or cool another creates a closed energy loop: a self sustaining energy system. The spatial consequence of this closed energy loop is a mixed program within one or a group of buildings. This has the benificial effect of creating more activity during the day, improving the quality of life socially as well as ecologically.
The total mix contains all functions to be found in the city, clustered in proportion to their heat vs. cold demand, to have a balanced exchange, which allows for the most efficient reuse of waste energy. The demand for electricity, plus the energy-loss in the heat exchange circuit are produced with sustainable methods.The proposed scheme can be applied to all parts of the city. Functions are chosen depending on demands from the city and complemented with functions depending on energy exchange. CO2 reduction becomes a urban planning tool.
Focusing on Vancouver we apply the scheme to three examples: a downtown city block, a suburban area and an entertainment quarter.
