None of the hundreds of existing green building rating systems is perfect. Some of them are too documentation-heavy. Some increase short-term project cost. Some aren’t rigorous enough or include contentious issues, writes HDR's Michaella Wittmann.
None of the hundreds of existing green building rating systems is perfect. Some of them are too documentation-heavy. Some increase short-term project cost. Some aren’t rigorous enough or include contentious issues.
But it would be extremely difficult to find many examples where the use of a sustainable rating system—whether actual certification was achieved or not—didn’t make the project better, either by shifting the way a project was discussed in terms of sustainability or inspiring a sustainable solution that brought value to the project.
I have worked on dozens of sustainability projects of all sizes, ranging from small non-profit office buildings to multi-billion dollar infrastructure projects. In all cases, if there wasn’t a commitment to a very specific sustainability goal, it was much harder to be sure that great sustainable solutions made it to the final design. Eventually I believe sustainability will rank right up there with schedule, cost, and design considerations in terms of priority, but for now, the topic is too often not afforded the same rigor.
At HDR, our philosophy is to drive sustainable solutions that are project-specific and bring value to our clients, communities and the environment. We want to know our clients’ specific priorities in terms of resource use, indoor environments, environmental impacts and the like.
Can we provide that solution to them without the use of a rating system? Possibly, but I would argue that sustainability rating systems provide a framework to drive a discussion about sustainability and help assure that good solutions get implemented.
We are so sure that rating systems help drive culture shift and encourage project teams to ask the right questions that HDR has adopted High-Performance Sustainability Requirements (HPSRs). While not a rating system per se, these requirements represent a set of sustainability goals and conversations that we believe need to take place on all projects. The objective of HPSRs is to drive conversations about sustainability.
In the media, a lot of attention is currently being given to the problems with various systems and which rating system is best. Let’s improve the systems but acknowledge the market transformation that they have assisted in making.
