A major trend for this year is related to post-occupancy evaluations and data. The green building industry has made the transition from merely getting everyone excited about building green to actually building green, projecting efficiencies and entering an era where the ‘proof is in the pudding,’ or, in this case, ‘the proof is in the post-occupancy data.’

In order to prove that green buildings are performing as well as the projections, we need to measure and track everything we want to impact positively, including seeing building performance as a system – energy, water, indoor air quality, and even the grounds associated with the building! The mere placement of a viewable and interactive meter can increase efficiencies 3% to 5%. As the old management adage goes, ‘You can’t manage what you don’t measure.’

In Alberta we have several emerging service providers to help measure and track performance. One such leader is ExactET, providing Climate Controlled Irrigation Services. Just by connecting to their network of local weather stations they can reduce a client’s potable water use for irrigation by 40% to 70%! Coupled with the use of auxiliary or grey water approved irrigation equipment, potable water use can be completely eliminated! ExactET’s services can aid in achieving up to 7 credits and one prerequisite in the new LEED-EBOM (Existing Buildings: Operations & Maintenance) Rating System.
