Communities throughout the world are developing district energy systems in response to rising energy costs and growing concerns about climate change.
In a shared district energy system, one or more centralized plants heat and/or cool individual buildings through a network of underground water pipes. In the right application, district energy improves reliability, energy security, flexibility to use a variety of technologies and fuels, environmental performance, cost savings, price stability, and economic development. Here in Portland's Pearl District, a single cooling system serves a variety of green buildings on several adjacent blocks. Similarly, institutional campuses throughout Portland benefit from shared heating systems.
