Through a cost-recoverable method known as Energy Performance Contracting, the University of British Columbia (UBC) undertook an enormous energy and water savings initiative over a three-year period. The aim of the project, Ecotrek, was to reduce University energy and water use, as well as greenhouse gas (GHG) emissions. Ecotrek is the largest project of its kind in Canada, and involved rebuilding and retrofitting the infrastructure of nearly 300 academic buildings. New technologies replaced aging infrastructure in order to reduce the amount of energy and water consumed by one of the largest campuses in Canada.MCW Custom Energy Solutions Ltd., a leading national Energy Service Company developed and delivered this project through an Energy Performance Contract. (MCW/CES provides single-source engineered energy management solutions to the Canadian building industry.)The Ecotrek project took three years to complete, at a cost of $35 million. Ecotrek improved comfort for building occupants, reduced core campus energy use by more than 20%, and reduced water use by 30%. With the completion of construction, UBC will be saving at least $2.6 million each year in electricity, steam, and water costs, paying for itself through accrued savings. To date, the project has already saved $3.8 million in energy costs, has reduced particulate emissions by 80% and has reduced GHG emissions by about 15.000 tonnes per year, or 25% of the baseline year in 1999. Specifics of the project include:? The lighting systems in 120 buildings were retrofitted with energy efficient components, saving considerable electrical energy and improving the light conditions for building occupants. ? Comprehensive repair and replacement to over 5 kilometers of condensate pipe was undertaken, to ensure the steam used in each building returns to the central plant for re-use. ? Exterior road and pathway lighting was replaced with the campus' new standard of exterior lighting. This completed a change-out of the old out-dated lighting, to the new modern and efficient standard. ? Major modifications to the Central Steam Plant reduced air-polluting nitrogen oxide emissions by 80%. ? The Building Management System (BMS) now automates approx. 90% of the academic campus. The BMS monitors and controls heating, cooling, and ventilation within each building. This allows operators and technicians to troubleshoot, and adjust any necessary functions anywhere on campus. It also allows systems to operate to match the exact occupancy of each building. This means UBC can save energy during unoccupied periods such as nights, weekends, and holidays. ? More than 3,000 low-consumption plumbing fixtures were installed in over 250 buildings, reducing water consumption by 30%. ? Drafty doors and windows in approx. 200 buildings were sealed in order to conserve heat within each building. ? Ecotrek funded the cost of installing photovoltaic solar panels at the Fred Kaiser building, offsetting some of the electricity needs of the building. ? As part of the project - and to ensure continued success and sustainable energy savings - MCW/CES has provided a range of training to Land & Building Services departmental staff. training on newly installed equipment and systems, to technical training on the operation and maintenance of major building components. MCW/CES are also offering the opportunity to attend accredited courses on the energy-efficient operation of buildings.
