PACE Chemicals Ltd. is a Canadian-owned and -operated water treatment company, specializing in energy conservation through treatment of hydronic HVAC systems. BC Housing research centre conducted a multi-year, multi-building study of the effects of EndoTherm and the PACE Eco program on its buildings. The result is a significant reduction in natural gas consumption and GHG emissions with no equipment upgrades required.
TO REDUCED ENERGY CONSUMPTION AND GHG EMISSIONS OF MULTI-UNIT RESIDENTIAL BUILDINGS THROUGHOUT THE BC HOUSING PORTFOLIO BY USING THE ENDOTHERM ADDITIVE TO IMPROVE SPACE HEATING BOILER EFFICIENCY.
After the successful small-scale pilot of EndoTherm, BC Housing contracted Morrison Hershfield to provide a 3rd party audit and report of a multi-building application of EndoTherm within its portfolio. The goal was to examine if EndoTherm would be a viable solution to reduce energy consumption and ghg emissions, to help BC Housing reach its emissions targets. The project included basic water treatment for corrosion control and the EndoTherm treatment to improve hydronic heat transfer and energy efficiency.
About the technology
The entire portfolio was evaluated and twelve multi-unit residential buildings were selected to receive the EndoTherm treatment based on the consistency of their historical energy consumption and that no other changes would be made to the building. Fortis BC (Gas Utility) partially funded the project as part of its Innovative Technology Demonstration Program. Upon completion of the second heating season the energy data was sent to Morrison Hershfield, a third-party engineering firm, for analysis.
1370 -2300 GJ/yr
Morison Hershfield concluded that, once all variables were isolated, EndoTherm provided a clear and measurable reduction of building gas consumption by at least 5%-8.4%. While this falls below EndoTherm’s average performance and verified lab results of 12-17%, public housing buildings have in suite temperature control, sporadic heat loss from open windows, which leads to greater variability in building energy consumption than typical residential buildings. Having verified significant energy and emissions savings with no issues, BC Housing is now applying EndoTherm and the PACE Eco Program to its portfolio of applicable buildings.
As part of the FortisBC Innovative Technology Demonstration program, the BC Housing results have formed part of Fortis’ review of EndoTherm. The successful results at BC Housing and other demonstration sites suggests the technology could receive rebate funding in the near future.
"EndoTherm helps reduce associated energy cost and GHG savings from our buildings. Along with being relatively simple to install, it averaged greater than 5% savings in natural gas with a simple payback period of 2.7 – 4.5 years."
