Like many communities around the world, UBC is striving to meet its energy needs while reducing its impact on the environment. The Bioenergy Research Demonstration Facility (BRDF) responds to this challenge while demonstrating small-scale power production that is relevant and replicable in other communities.
In addition to generating energy for the UBC campus, BRDF is also a Campus as a Living Lab project integrating our core academic mandate of research and teaching with infrastructure and operations.
TURNING WOOD WASTE INTO THERMAL ENERGY
Located at the UBC Vancouver campus, the Bioenergy Research and Demonstration Facility is an energy generation facility that processes renewable biomass sourced from urban wood waste and transforms it into synthesis gas (syngas) to generate thermal energy for heating campus buildings.
In addition to the thermal system, the facility houses a biomass combined heat and power demonstration system that originally employed the syngas, after conditioning and filtering it from impurities, to fuel a cogeneration engine. This demonstration technology was in operation for 450 hours before it was stopped due to an equipment failure, which was not economically feasible to repair or replace. The cogeneration engine is currently fueled by a mix of natural gas and renewable natural gas.
The BRDF produces 8.4 MW of thermal energy, which accounts for 25-32% of the total campus heating and hot water needs each year and 100% in the summer months, as well as 2 MW of electrical energy, which accounts for 5% of the total campus electricity requirements each year.
The building that houses this facility features an innovative mass timber structure, consisting of cross-laminated timber (CLT) floor, walls and roof, and glue laminated (glulam) columns and beams attached through steel connectors.
This was one of the first industrial buildings in Canada to be constructed with CLT panel technology, mostly from regionally sourced lumber and fabricated locally. The building structure and the facility operations are available for public viewing and tours.
REDUCING GREENHOUSE GAS EMISSIONS
The BRDF is a key contributor to UBC’s greenhouse gas (GHG) emissions reduction efforts through switching from natural gas use to biomass and reducing reliance on fossil fuels. Furthermore, the biomass used at BRDF consists of ground and chipped wood waste mainly from sawmill residuals and municipal trimmings that would otherwise go to a landfill.
The amount of carbon dioxide released by the wood waste used as fuel is the same as would be released if it was left to decompose in the landfill but with the benefit of producing energy, which makes this process carbon neutral.
The facility displaces around 8,500 tons of emitted fossil fuel-based CO2annually and has contributed a 14% reduction in UBC’s GHG emissions compared to 2007 emission levels. In total, UBC has reduced GHG emissions by 34% since 2007, the year in which the University met targets established by the Kyoto Protocol.
The building’s structure contains around 698 cubic meters of mass timber that store 627 tons of CO2. According to the Canadian Wood Council Carbon Calculator, choosing a mass timber structure for this building avoided the emission of 243 metric tons of CO2, the equivalent of taking 184 cars off the road for a year.
By showcasing the application of CLT panel construction for an industrial building, BRDF became an example of a viable renewable material alternative for non-combustible structures.
INTEGRATING RESEARCH, OPERATIONS AND EDUCATION
Winner of the International District Energy Association (IDEA) Award for Innovation, UBC’s Bioenergy Research and Demonstration Facility integrates research, operations and innovative technologies into a single facility.
The on-site laboratory within BRDF allows researchers to use the biomass supply, syngas, and system by-products for research purposes, as well as using the facility’s systems as a case study to advance bioenergy production. Likewise, incorporating the novel biomass-to-power demonstration system in BRDF promoted research collaborations with industry partners to improve the technology for future applications.
The BRDF has engaged students, researchers, faculty and staff on all levels to learn about UBC’s energy systems and further their studies. More than 1,000 people tour the biomass facility each year to learn about the technology, the building and how this unique facility supports campus life.
This integration of operations and academics challenges the campus community to work across traditional boundaries and sectors to affect change, exactly what this Campus as a Living Lab project strives to achieve.
