Reducing Energy Consumption
Trinity uses steam, natural gas and electricity to heat, light and power its buildings, and to cook in the kitchens. The energy consumed by these utilities can be converted to a standard measure: "equivalent kilowatt-hours". Through a concerted and systematic effort, the College has been able to reduce energy consumption by 30% over the last 4-5 years, as illustrated in the accompanying table.
Some of the reductions have been achieved simply by more careful attention to our operations, like turning off lights and equipment when not needed. All members of the community, from maintenance staff to students, have contributed to the savings. Other reductions have been achieved by investing in repairs and in new, more efficient equipment.
Weather can have a significant impact on energy consumption. A cold winter drives up steam consumption and a hot summer drives up electricity consumption for air conditioning. The College is determined to maintain the gains it has achieved and is constantly looking for new energy reduction opportunities.
