Having developed the energy modeling criteria for Built Green, Rushing knows the protocol inside and out. To reach the required energy efficiency threshold for Built Green 4-Star (15% better than WA State Energy Code), Rushing’s team built a baseline model using WSEC-mandated values alongside a model reflecting building design. Using these models, Rushing provided a list of energy conservation measures for the project which resulted in exceeding the Built Green 4-Star requirement of 15% greater energy efficiency over WA State Energy Code.
As a certified Built Green Third-Party Verifier, Alexandra Ramsden conducted evaluations which enabled the project to attain the 4-star rating. Specific Built Green components pursued for Lexicon include selection of ENERGY STAR appliances, low flow plumbing features, efficient apartment lighting, low-VOC materials, native plant species used in landscaping, and exterior cladding with recycled content.
In conjunction with the City of Seattle Green Factor program, the building exterior includes a small green roof, water-efficient irrigation system, and integration of landscape elements which mitigate stormwater runoff.
