Project – Whitmore Lake High
The new Whitmore Lake High School has achieved LEED Silver certification, and was designed for both sustainability and environmental sensitivity. One of the most interesting features is a 590-foot by 490-foot geothermal field of tubes and pipes buried near the school building which transfers heat from the ground to the high school through heat pumps. This system is expected to save the school district a significant amount of utility costs.
HEA provided building commissioning services of all mechanical, electrical, plumbing and fire protection systems throughout the design phase through construction and turnover. The program for the school included classrooms, science laboratories and lecture rooms, a media center, a cafetorium and stage, a two-court gymnasium, an elevated walking and running track, and a six-lane pool.
Project – Springfield Central High School, Science Lab
HEA was hired by the Massachusetts School Building Authority (MSBA) to provide commissioning services for both the construction of new laboratories (added via an addition to the building) and the renovation of existing labs. The 30,000 sf, three-story addition included 12 labs and associated prep rooms. The renovation of the third floor included renovating 6 existing labs white retrofitting the remaining 6 labs into classrooms. The project consisted of multiple phases, with the school staying occupied during construction. This created challenges for all project team members but due to HEA’s planning, the systems were successfully brought online to meet the needs of the school. Consistent coordination and communication between HEA and the project team allowed for the documented issues to be corrected.
