    By incorporating high-mass construction using Brick Masonry wall and Brick Veneer Wall, cooling loads can be reduced and air conditioning equipment can be downsized.

Organizational Assistance

  • Initial Cost
    The shell of the building is a major investment that should be purchased on a "life-cycle costing" or return-on-investment basis, rather than at lowest initial cost. Over the life of the building, the energy operating savings from a well built building will far outweigh the initial cost of the structure. Plus, in the case of new construction, it will be less costly to "do it right the first time," than to make costly upgrades to insulation, windows, walls, or roofing material later.
  • Insulation
    The building shell is typically responsible for 10%-23% of the total energy consumed in a school. Focusing on this area of design can help reduce energy consumption in your school building. Increased insulation in the walls and ceiling helps to reduce heat loss and gain and improve comfort. Incorporating masonry wall systems designed with the exposed mass inside the insulation envelope allows the mass to be utilized to store thermal energy from passive heating strategies.
    Wall insulation should be selected based on the likelihood that it will never be replaced. When selecting wall and roof systems, it is critical to choose what is best for the life of the facility. Specify interior and exterior finished that are both durable and maintenance free. Choose maximum insulation levels and strategies that eliminate air infiltration.
    By incorporating high-mass construction using Brick Masonry wall and Brick Veneer Wall, cooling loads can be reduced and air conditioning equipment can be downsized.
  • Walls and Roof
    Light-colored exterior walls and white roofs reduce heat island effect and help to reduce cooling loads. These factors also contribute to reducing the size and cost of HVAC system needed. The useful life of building materials, systems, and equipment incorporated in school can vary considerably, so initial building shell decisions will impact both the first cost of the school as well as the long-term costs associated with operation, maintenance, and replacement.
  • Framing
    Advanced framing system must be implementing in building the school. Advanced Framing is a collection of techniques to reduce construction waste and the lumber required for wood-framed houses, while increasing energy efficiency and simplifying framing layout.
    If specified correctly, energy- efficient building shell elements can be effective in reducing our impact on the environment, and they will never need to be replaced.
