A History of Energy Conservation

Linfield College

Linfield College has a long history of reducing its carbon footprint through the implementation of energy conservation projects. Over 79% of all campus buildings use natural gas to heat buildings and produce hot water; The remaining 21% use electricity as a source of energy to heat space. In an effort to reduce energy consumption for heating, cooling, hot water production and lighting the college has developed a comprehensive energy conservation plan, which has yielded extraordinary results. Over the last decade the college has cumulatively saved 1.8 million Therms of natural gas, which is equivalent to heating 1837 homes/year and saved 10.3 million kWh hours of electricity which is the equivalent of annual electricity used for 687 homes for one year

Energy Saving Projects developed and implemented over the last decade:

Installed 1.6 miles of energy efficient double walled steam lines to eliminate leakage.
Replaced 16 inefficient boilers to 2 highly efficient units.
Replaced 500 steam traps to increase boiler efficiency.
Installed highly efficient DDC controls and advanced Computerized Energy Management System (CEMC) to monitor and control over 3000 control points in the heating, cooling and ventilation systems.
Replaced over 10,500 inefficient lights with high efficient T8 fluorescents and CFLs.
Over 400 ballasts were changed over to electronic units which are more efficient.
Light motion sensor were installed throughout the campus to control lighting
Installed energy efficient chiller with DDC controls.
Installed energy efficient T5 lights in athletic gym spaces.
Installed insulation in attic and crawl spaces in campus apartment complexes and other student living spaces.
Installed double pane energy efficiency windows in four apartment complexes.
De-lamped and installed reflectors in ? light fixtures to reduce energy consumption by half.
Installed LED down lights in lobby and hallways in the Gym.
