Inquiry

Our project covers multiple buildings with different space types including offices, classrooms, labs, and cleanrooms. Labs and cleanrooms can be very energy intensive due to large outside air requirements and filtration efficiencies not to mention the electrical energy consumed by process tools and the natural gas consumption required by process systems. Some of these buildings have Class 1 rated cleanrooms, process tool energy consumption levels that make up 50% or more of the total EUI (Energy Use Index) and clean room and lab spaces that constitute the majority of the square footage of the building. In an attempt to satisfy LEED EB version 2.0 EAp2 requirements, we have reviewed all the options possible and have found that none of them are well suited for buildings with labs and cleanrooms. Currently, labs and cleanrooms are not one of the space types available within the Energy Star
