KIF_3125At RBGB, our mission is to help project teams create energy efficient, sustainable, high performance green buildings and maintain that high performance over the life of the building. We have a large bank of experience, technical tools, and green building know-how that we tap into for all projects. These pages are the beginnings of a collection of thoughts, tips, concepts and instructions that deal with specific green building issues to help create a greater level of knowledge within the community.

The United States Green Building Council (USGBC) develops and administers the Leadership in Energy and Environmental Design (LEED) rating system. LEED is a voluntary point based system that covers five main areas of sustainable design including site, water, energy, materials, and indoor environmental quality. Based on the total number of points achieved, various levels of certification are awarded and these levels are: Certified, Silver, Gold and Platinum. Continue reading


An underlying goal behind advancements in the building energy sectors, including standards organizations, high performance building design guides, various green building rating systems, and initiatives such as Architecture 2030 is to steadily improve energy performance through technology development and application to the point where Net Zero Energy Buildings (NZEB) will be a practical reality in the years to come. Continue reading


Common to many LEED projects is to produce an energy model on a completed design for the sole purpose of estimating points. This is the “how lucky did we get” approach. Thus, the energy model tool is not fully utilized, the modeling costs become an overhead, and opportunities for performance improvements are lost. It is under this scenario that the energy model gets labeled as having no value. Continue reading
