Join us as Finegold Alexander presents the study for the Lowell Trial Court, a 250,000 SF state courthouse designated by Gov. Patrick’s Zero Net Energy Building Task Force as one of three public demonstration projects addressing the challenge of designing public buildings to high sustainability standards.
The engineering components of the study involved proposals for energy reduction and on-site production, investigated through a multitude of computer models and cost-to-benefits charts and analysis. Architecture and architects must change. Architectural form is a critical element in achieving any sustainable goals, including zero net energy. This session will look at the Lowell Trial Court design process and the iterative schemes the team produced. We will discuss building massing, orientation, urban context and all the elements we always address in every project. Now we find our attitudes toward these traditional design criteria are influenced by the integration of sustainable design. Design for zero net energy caused this team to think and collaborate differently with consultants, client and user groups.

The energy story is based on a methodical approach that has proven to be both life cycle cost effective and capable of achieving factor 4 (75%) or greater energy savings. It is summarized in the accompanying graphic, highlighting 6 steps of cumulative performance improvement. It is coupled with the operational carbon story in step 6 through the use of green power purchasing (equivalent in many respects to carbon trading).
