Air filtration is a critical issue, and should be addressed beginning in the design phase. Systems and materials are key factors in avoiding problems. Proper construction is imperative in ensuring that the design and system function as they should.
An inferior air infiltration system causes a loss of heat and air conditioning efficiency. The financial impact can be enormous in terms of both operating costs and the potential costs to remedy the situation. In addition, inefficient climate control can make building occupants uncomfortable, reducing a building's function and making it less attractive to tenants.
Water infiltration can result in severe building damage and deterioration, and the impact can go far beyond the high cost of repair. The possibility of mildew and the development of toxic mold raise serious health and liability issues as well.
Addressing this issue should begin in the design stage. The systems and materials must be appropriate for the design and function of a building. Proper construction is, as always, imperative.
Structural Performance Deficiencies
Buildings with high-performance walls must adhere to stringent structural requirements regarding imposed loads on walls, live load deflection, deadloads and performance wind loads.
Inadequate Thermal Performance
All building owners have cost concerns associated with the building process. Yet cutting corners in the performance and design of materials in the front end can cause costly long-term problems in thermal performance.
Poor Weather Resistance
Inferior installation and inadequate wall systems can lead to poor weather resistance, the cause of a variety of problems including water and air infiltration, possible toxic molds and high maintenance costs.
Fast-paced projects with tight design-build schedules require the services of an experienced curtainwall installer who knows the system. The subcontractor can work with general contractors and building owners to determine what the imposed wind loads will be at each location of a building - before shop drawings are approved. This level of knowledge is especially important for critical approval time and limited schedule durations.
