Energy Conservation & Demand Management
In 2014, Western determined a set of Energy Conservation Goals that would help us drive investment and innovation within our facilities. These goals included:
- Achieving a 9% reduction in energy use intensity (ekWh/m2) below 2012 levels
- Reducing overall energy use by 4% below 2012 use
- Reducing direct Greenhouse Gas (GHG) emissions below the 2009 baseline
- Reducing water use intensity (m3/m2) by 8% below 2012 levels
Facilities Management continues to support these and more conservation and demand managemnet intitaives. The following are some of the recent projects undertaken with conservation outcomes;
topEnergy and water efficiency and conservation
Our newest document, Western's Sustainable Design Guidelines, will help ensure that any major, minor and site construction and renovation projects target efficient energy and water systems.
topGreen Building certifications
Over the past few years, Western targeted to achieve a minimum of a LEED® Silver certification for most of our major construction and renovation projects. Since 2014, we have added 8 more LEED® certified buildings, and by 2018, 18% of our building footprint will be comprised of certified green building space.
topTraining and Education programming
Western has developed and delivered a variety of training and educational programming for students, staff and faculty, oriented towards energy conservation. An example are our Sustainable Building Workshops for graduate students and the Green Building Tours, which have been delivered to dozens of people, teaching them about sustainable design, construction and energy/water efficiency.
Over the past few years, the Facilities Management team, in collaboration with other units and areas on campus, have worked on implementing a Demand Management program, which allows us to reduce our electricity consumption used for cooling our buildings.
Western has installed steam meters in all of Central Campus’ buildings, with the purpose of enhancing business operations, preventive maintenance, research projects, raising awareness among the community, enhancing building performance and supporting our energy management efforts
We have installed new insulation and removable covers in our steam and condensate pipes, to reduce heat losses and enhance the performance of our mechanical systems.
We believe in the use of more efficient lighting sources. We have conducted lighting retrofits in existing buildings, including: incandescent lamp replacement, removal of remaining T12 lamps, installation of LED lights, occupancy sensors, ballast replacement and installation of T5 lamps and fixtures. Overall, these alternatives will help reduce our electricity consumption while providing the appropriate lighting levels in our buildings.
Major losses in coolign and heating happen in entrances and exits of buildings. By improving weather-proofing in older buildings, with a key focus on entrances and exit, we can help reduce the amount of cooling and heating needed to maintain thermal comfort of our building occupants
Western is world-class, research-intensive university. And as such, we believe that all departments within Western should work together to foster excellence in research. Facilities Managemetn works closely with Western’s faculty and researchers in the development and implementation of research projects related to utilities management, conservation efficiency and behavioural change in buildings
topEnergy conservation initiatives
We are looking to implement energy conservation initiatives that help engage students, staff and faculty in energy conservation within their living/working/studying places
You can't manage what you don't measure. This directive encouraged Western to develop an in-house energy dashboard with real-time energy, covering all of Western’s buildings; www.energy.uwo.ca
topEnergy efficient equipment, systems and designs
Not all projects at Western are major construction and renovation. Equipment retrofits and minor construction projects are also enhanced by the use of energy-efficient equipment (e.g., boilers, water heaters, heat exchangers), systems (e.g., VFD-controlled motors) and designs
topChilled water distribution system
Western has a large chilled water distribution system on campus, which helps with the cooling needs of our buildings. This system has been optimized by installing new valves, improving the temperature difference, removing unnecessary pumps and improving chilled water bridges
One of our first efforts at Demand and conservation managemetn, we conducted ASHRAE – Level I and II audits of select buildings to identify efficiency and conservation projects
Also related to research, and some teaching activities as well. Western has a large number of laboratories that utilize special equipment. One of those equipments which was identified to be used in a more inefficient way are our fume hoods. We improved controls in laboratories to reduce the air flow in fume hoods when units are not in use, alerting users of fume hoods left open, performing a setback of the rooms’ systems when unoccupied and control differential pressure more efficiently
