Zero-Net and High Performing Buildings (LEED, CalGreen, Well, etc.) require an integrated design approach, with all members of the design team exchanging information. In addition to the environmental benefits, it can also result in better coordinated documentation, reducing unexpected construction costs and delays. Most of the work we do is in the realm of High Performing buildings, and we have been part of many successful collaborations.
