Water conservation is gaining importance across our portfolio due to rising costs in a number of municipalities, increased government regulations, and as climate change begins to impact water supplies in some geographies. In 2016, actual water consumption was 7,466,353 m3^  and has increased by 1.1% since 2012 when adjusted to reflect any acquisitions, dispositions and completed new developments. In particular, multi-family properties across North America saw the greatest increase in water consumption. We will continue to increase tenant awareness on water conservation through the ForeverGreen @Home Resident Engagement Program.

water intensity

Normalized water intensity is shown as litres per square foot on an annualized basis and is normalized for weather, occupancy and exceptional tenant loads and includes newly developed buildings but does not include buildings that have been acquired or disposed of in the past 5 years. 

  • Overall, water intensity has decreased across both Canada and the U.S. portfolio since 2012, with a 6.8% decrease in Canada and a 2.7% decrease in the U.S.
  • The most notable declines in water intensity by asset-type were U.S. and Canada Office portfolios. These improvements have largely been driven by an increase in building certifications through the LEED Volume, BOMA BEST, and IREM Portfolio Programs, each of which have a strong focus on water efficiency. All water reported is from municipal water sources and does not take into account on-site capture or re-use.

Water savings enough to fill 77 Olympic pools

14.5% decrease in normalized water consumption across our Canadian office portfolio (2012-2016) is equivalent to the volume of 77 swimming pools.
