Building better urban areas with district heating and cooling

Since the construction of the first district heating and cooling system in 1970 at the Senri Chuo Area in Osaka, the focus of attention has shifted to how such systems could be used to reduce pollution.  And over, municipalities have begun to direct their attention to the many benefits offered by district heating and cooling in terms of urban planning, renewal, and energy conservation to the point where now these systems have become an essential part of the infrastructure.
