Proper Setup of HVAC System in Conjunction with Sound Building 'Skin' Design for Alleviation of IAQ and Energy Performance Problems

Abstract

Energy consumption in buildings is a growing concern. Many buildings are energy hogs simply because they were not set up properly to begin with. The building envelope and infiltration of unconditioned air is also a major concern in hot and humid climates, not only because of the loss of energy, but also because of damage that can result to insulation, drywall, and structure in addition to promotion of mold and mildew growth. Proper setup of the HVAC system, in conjunction with sound building “skin” design, can alleviate many of these problems. This paper will explain how most mixed air HVAC systems are set up with problems to begin with and how to identify and solve those problems. It will explain different control schemes that specifically deal with proper building pressurization
