Vancouver Airport (YVR) Lowers Natural Gas Consumption 17.32% with EndoTherm


Vancouver International Airport (YVR) is committed to sustainability with a focus on reducing their carbon footprint. As part of the airports Environmental Management Plan, YVR has a target to achieve net zero carbon emission by 2050. Part of this target is to reduce direct greenhouse gas emissions from airport operations. A major source of airport operation emissions is from the natural gas consumed to heat airport buildings.   


Having previously provided water treatment services to YVR, Pace introduced the airport’s sustainability team to EndoTherm in 2017. The team established an EndoTherm measurement and verification project at the South Terminal. The South Terminal was selected because the building’s gas usage was isolated to the boiler system. The site’s monthly gas consumption had a tight correlation between gas usage and heating degree days.

The post EndoTherm installation data was compared to the building’s previous 24 months of consumption by analyzing gas consumption to Heating Degree Days (HDD) from the onsite weather station. Efficiency performance was determined following the guidelines of the International Protocol for Measurement & Verification of Performance (IPMVP). The result was a 17.32% reduction in natural gas consumption, showing a savings of 198.17 GJ and 10 metric tonnes of CO2e within the three months evaluation period.

Vancouver International Airport is working to reduce greenhouse gas emissions by 33% by 2020. We are excited to see the reductios offered by use of products such as EndoTherm

 About the technology

EndoTherm is a low concentration, water additive for boilers, designed to lower surface tension of the system water to improve heat transfer. By improving water’s ability to transfer heat throughout the building, EndoTherm creates a condition that is optimal for efficiency gains within the HVAC system. Buildings hit temperature setpoints quicker and boilers are required to run less frequently to maintain heat, therefore saving significant amounts of natural gas and GHG emissions. EndoTherm is an economical way to maximize the efficiency of the existing system without downtime or large capital investment.
