Integral Group is providing MEP Engineering and Sustainable Design Consulting services on the new campus design for Boulder Commons in Boulder, Colorado. This developer-led project consists of two 50,000 square foot speculative office buildings, and will also include amenity retail and restaurant spaces. The project is being designed to achieve Net Zero Energy (NZE) with the additional goal of proving the financial viability of NZE for commercial buildings.
The buildings are being designed with appropriate bioclimatic and passive design strategies to minimize energy use while maximizing comfort and connection to the outdoors. Some of those strategies include daylight harvesting, aggressive exterior solar shading, automated interior blinds, natural ventilation, a highly insulated and air-tight envelope, and the use of thermal mass to regulate internal temperatures. A high efficiency variable refrigerant cooling, heating and ventilation system will be utilized to maximize free heat recovery for the buildings while providing a simple, flexible and low energy HVAC solution that can be easily reconfigured to serve all types of future tenants, small to large.
A large photovoltaic (PV) array will be installed and sized to offset all of the energy that the campus uses over the course of a year, in order to achieve the Net Zero Energy goal. In addition to covering the roofs with PV, this project will be one of the first to achieve NZE utilizing vertically mounted PV as part of the exterior façade of the buildings.
The campus will also be designed to incorporate numerous strategies from the Well Building Standard to enhance the indoor environmental quality of each building and occupant wellness campus-wide.
