The LEED system now has almost 11,000 credit interpretations. Doesn't that strike you as the sign of an excessively complex and complicated approach? Why can't we design a much simpler system focused on absolute performance instead of relative improvement, by using just Key Performance Indicators (KPIs) for energy, water, waste and Scope 3 carbon emissions. You can add a straightforward approach to sustainable purchasing if you like. That's it - use the KISS principle: Keep It Simple & Sustainable!
Green homes offer significant marketing advantages, but the plethora of certification systems means that LEED and NAHB programs split about half the market, with some 80 local, state and regional systems sharing the other 50%. LEED's uptake is 80% in the multifamily market, but only in new construction. The real issue continues to be how to make significant changes in resource efficiency in the existing homes market, which generates about 20% of US carbon emissions.
Future green building rating systems should be designed more like sculpture than painting - instead of piling on one consideration after another, they should seek to remove just about everything that is not essential to the main goal: cutting carbon emissions. That means they need to be designed with the end-user in mind, keeping the system: Smart. Simple. Sustainable.
