Lower Energy Costs
With district thermal energy, a building only purchases the energy it needs to meet its requirements with 100% efficiency. Comparably, fossil fuel systems are only 85% efficient incurring a 15% waste factor of unusable energy emitted to the smoke stack. District heating has no ongoing capital expenses to upgrade, rebuild, or maintain excess capacity. In-building boilers typically carry excess capacity to meet occasional peak demand, which leads to inefficient partial boiler loading during most of the year. This results in poor seasonal efficiency. By contrast, Juneau District Heating is operated to achieve the highest seasonal efficiency possible.
