While at Greenbuild 2012 I was asked “What do you think is the most critical factor in ensuring a healthy, sustainable built environment?” My answer was posted on our Blog but there is more I want to say about this so here we go!
Users or occupants of high efficiency buildings need to understand and be a partner in the process because ultimately they influence the success or failure of a building’s efficiency over time. For example, Leadership in Energy and Environmental Design (LEED) for Homes will give you credit for and requires Energy Star performance which means certain insulation levels, certain air tightness and certain efficiencies on the mechanical systems (among other issues). The energy efficiency of the building is based upon a combination of highly efficient equipment and permanent passive systems.
When the active system wears out, if the consumers don’t appreciate the importance of the efficiency of that system on the overall performance of the habitat they are unlikely to take that into consideration when they have to replace equipment. They can go from a high efficiency piece of equipment that made their sustainable building sing beautifully and perform wonderfully and stick in something that is on sale or is perhaps promoted by their contractor but with a whole different efficiency rating. Now the building goes from being a Prius to being a Hummer simply because the driver wasn’t told the difference between the two.
In sustainability circles we often talk about “the Prius effect”. This comes from the engagement of the driver with the car. Once the driver understands the savings due to the offset of the electrical to the fuel and you give them real-time feedback, they began to drive against the machine to improve the efficiency. The build community needs to develop dashboards or other tools for high efficiency buildings so that end users can see the benefits provided by the systems. That buy-in is critical to sustaining efficiency over the life cycle of the building.
There is no point in doing a sustainable building for someone unless you teach and show them how to maintain it. That is one aspect I especially admire about the Living Building Challenge. The Beauty petal has components which include inspiration and education. Couldn’t we all use a little more of both?
