Harvard Evans Music Classroom – Portland Public Schools – Portland, Oregon _


Design / Energy Modeling / Retro-Commissioning


The Harvard Evans Classroom is located on the campus of Da Vinci Middle School in Portland, Oregon. This classroom is a high performance stand-alone building that was designed to be an example of sustainability and energy efficient design in K-12 buildings. It was the first net zero energy project for Portland Public Schools. Built in 2008, it houses the music classroom and practice space for the school’s band and music program.  This building achieved the highest nationally recognized certification (LEED Platinum) from the United States Green Building Council (USGBC) Leadership in Energy and Environmental Design (LEED) program.  Solarc contributed their resources in several phases of the project including mechanical and electrical systems design, energy modeling for LEED certification, and Retro-Commissioning (ReCx).


During the initial design and construction phase Solarc was involved by providing the electrical and mechanical design work for the project. Solarc worked closely with SRG Partnership to ensure the mechanical and electrical design was properly integrated into the architect's design. Once design was complete, Solarc used a whole building energy modeling software (eQuest/DOE2) to model the design for LEED energy credits. The project was able to achieve 10 LEED credits which helped the project ultimately reach their goal of LEED platinum.


The second phase Solarc was involved with was ReCx the building in 2014. After years in operation the school district noticed the energy bills were no longer aligning with the projections in the LEED energy model. Solarc worked with Portland Public School District to analyze the operational deficiencies of the building and strategize a plan to allow the building to function as originally designed.
