Northern High School-Calvert County, MD
Calvert County, Maryland New Northern High School Breaks Ground.
Calvert County Public Schools Board of Education has selected architect GWWO to design a replacement school for Northern High. The new Northern High School will accommodate 1,500 students. This will be Calvert County Public School’s first Leadership in Energy and Environmental Design (LEED) project. LEED is the most widely used green building rating system in the world. Available for virtually all building project types, from new construction to interior fit-outs and operation & maintenance The plan calls for construction of a new 200,000-square foot facility. Interior renovations and addition of 3,800-SF to the current arts center are include in the plans for the schools renovation project. In an innovative move for a high school, the design incorporates a central quad that will serve as the heart of the campus. New vehicular traffic patterns will create clearer and safer site circulation for cars, buses and pedestrians.
The project will cost over $80 million dollars and is projected to last about three and a half years. The new building will completely replaces the currently standing Northern High School facility. Located in Owings, Md, the school was built in the 1963. The new school will be built next to the existing facility, which will be demolished to make room for a parking area once the new construction is complete. The new Northern High School will seat 1,440 students, interconnect with the Mary Harrison Cultural Arts Center. The school will contain a geothermal heating and cooling system. The phased construction of the 244,090 square foot building will be completed in 2019.
Scope of the Project
For this job the general contractor Scheibel Construction contacted us to use both a spray foam insulation and air barrier system throughout the schools building. Demand for SPF is increasing in both new construction and retrofit applications. More architects, contractors, and developers are using spray foam in the walls and building envelope as well as on the roof of buildings. That’s because SPF has multiple attributes, notably air sealing, thermal performance, and structural performance.
Air barrier systems: The relationship between a building’s air tightness and its energy consumption is not a new concept; however, researchers in the past have focused largely on the non-energy impacts of air leakage such as thermal performance, moisture damage of exterior wall components, and poor indoor air quality. Transition Membrane (a type of air barrier) is a flexible air barrier membrane used for detailed areas on vertical above-grade wall construction. Used with a waterproof air barrier membranes, it provides flexible connections to achieve continuity of the air barrier assembly. It also functions as a secondary weather seal at joints in construction. The durable material is a fully adhered product that will not peel at the edges or stain due to adhesive leaching. The flexible material works for both static and dynamic joint conditions, and applies without specialized labor or tools.
