NESEA Pro Green Building Tour - Commercial Solar Headquarters in Central Vermont, Friday, November 17, 1 to 5pm
Event Description

This Pro Tour will bring attendees into the recently completed, net-positive headquarters of SunCommon, a company providing photovoltaic array financing, leasing and installation in Vermont and New York State. Hosted by the project team from Maclay Architects and Energy Balance Inc., this half-day tour of the 15,000 square-foot project will highlight the design process and unique challenges of a commercial developer "built to suit" project while providing insights into the performance data from the building’s first year of occupancy.

Maclay Architects designed the SunCommon headquarters to be both a high-performing building in terms of energy use and a healthy, productive workplace for SunCommon employees. The central common space serves as a welcoming space for visitors, SunCommon employees, and community events.

The layout strategically positions workstations around the periphery so employees have access to views and daylight. The central conference rooms with skylights provide acoustic and visual separation to the open work spaces.

Energy Balance, Inc., provided HVAC systems conceptual design and performance specifications for air source heat pumps and energy recovery ventilation systems, as well as enclosure consulting and commissioning services. Systems and services were designed to be economical for this developer-built project.

During the opening presentation, Maclay Architects and Energy Balance Inc., will discuss lessons learned from the various stages of this project, including the strategies that were employed to design a system that uses the simplest and lowest-cost controls and HVAC options. They will detail the highly efficient mechanical system strategies, which include an air source heat pump system with individual thermostats for each head unit and ERVs controlled by occupants and CO2 censors. Attendees will also learn about the strategic way the building was situated for a balance of best views for the occupants and maximizing solar capture of the roof PV array and on-site carports.
