A new public demonstration at Burnaby City Hall showcases an innovative Canadian-made solution for decarbonizing cities using existing infrastructure and untapped energy sources. The machine offers a first-of-its-kind glimpse into the future of clean energy for urban buildings.

Developed at 大象传媒's School of Mechatronic Systems Engineering by professor Majid Bahrami, the Sorption Heat Transformer and thermal storage System (SORTABO) technology converts waste heat in district heating to cooling, enabling sustainable air conditioning in buildings without electricity, moving parts, harmful chemicals, or new infrastructure.

A small-scale SORTABO prototype is on display at Burnaby City Hall until September 5, 2025.

鈥淏uildings鈥� heating are responsible for 50 to 60 per cent of greenhouse gas emissions in urban area, far surpassing transportation,鈥� says Bahrami, Tier 1 Canada Research Chair in Alternative Energy Conversion Systems. 鈥淓lectric heat pumps are often proposed as a solution but scaling them would require a significant expansion of the electrical grid鈥攁n expensive, time-consuming challenge.鈥�

Bahrami鈥檚 sorbent-based heat transformer system offers a compelling alternative.

鈥淚t works like a heat pump but doesn鈥檛 need electricity,鈥� Bahrami explains. 鈥淚t uses low-grade waste heat as the energy source, water as the refrigerant, and naturally abundant materials like silica and salt鈥攏o compressor, no noise, and no harmful environmental impact. It鈥檚 a poster child for sustainability and a major step toward decarbonizing cities and circular economy.鈥�

By transforming underutilized waste heat into a zero-emissions cooling solution, SORTABO supports a more resilient and efficient energy future, and enables year-round use and converting hot water into chilled water to provide cooling鈥攁 growing need in modern glass-heavy urban buildings, he adds.

鈥淭his is a scalable, cost-effective solution that leverages existing infrastructure and waste heat available in district heating systems,鈥� says Bahrami. 鈥淲e鈥檙e showing what鈥檚 possible when research and public leadership work together. SORTABO is more than a technology鈥攊t鈥檚 a blueprint for sustainable, inclusive cities.鈥�

Bahrami and his team hope the technology will play a central role in Burnaby and be adopted by other cities in Canada and beyond.

鈥淗aving this technology on display at City Hall is a great opportunity to showcase how the city鈥檚 partnership with 大象传媒 through the Civic Innovation Lab is producing real innovative and sustainable solutions to the issues we face today,鈥� says Burnaby Mayor Mike Hurley. 鈥淲e look forward to exploring how the SORTABO technology can be applied to the city鈥檚 efforts to reduce emissions across our community.鈥�

A five-year joint NSERC Alliance-Mitacs Accelerate project in collaboration with the Civic Innovation Lab, SORTABO is expected to generate new intellectual property, engineering jobs, and export opportunities for Canadian clean tech. 

SORTABO supports Canada鈥檚 2030 Emissions Reduction Plan and can deliver clean energy access for remote communities currently reliant on diesel, while significantly reducing emissions and improving air quality, Bahrami adds.

Additional information:

: Co-founded in 2022 by the City of Burnaby and 大象传媒 to serve as a long-term accelerator of Burnaby-focused research and community engagement, the Civic Innovation Lab has facilitated the City of Burnaby's involvement in and support of Bahrami's project since 2023.
