Field Evaluations: N/A Code Acceptance Summary The Air Conditioning Contractors of America (ACCA) guidelines for sizing HVAC equipment, ACCA Manual J Residential Load Calculation, enables contractors to estimate heating and air conditioning loads more accurately. Using Manual J, a contractor calculates heat loss from the building through walls and ceilings, leaky ductwork, and infiltration through windows, doors, and other penetrations as well as heat gain into the building from sunlight, people, lights and appliances, doors, walls, and windows, and infiltration though wall penetrations. Design conditions for the area are also used as inputs into load calculations. Air infiltration measurements must be estimated unless a blower door test is performed. The use of blower door test results will provide more accurate sizing calculations at a slightly higher design expense. Again, increases in design costs can be offset by decreased equipment size which lowers initial cost.

In most cases, this system has been operating for some time without much attention. Dirty ducts can circulate odors, contaminates like mold, and irritating dust throughout your building or home. Duct Cleaning Is Not Always the Best Answer Why waste money on unnecessary duct cleaning? SERVPRO Professionals can inspect your HVAC system and ductwork, and make recommendations about the best way to address any indoor air quality concerns. In circumstances such as after a fire, smoke, or suspected mold damage, duct cleaning is not optional in the clean-up process. SERVPRO's System is Cost Effective SERVPRO Duct Cleaning Process Patented equipment includes a roto-scraper which automatically adapts to the duct shape while traveling through the duct, removing debris and filth before vacuuming begins.

179. WBDG: High—Performance HVAC The term hvac refers to the three disciplines of Heating, Ventilating, hvac systems are sized to meet heating and cooling loads that historically occur http://www.wbdg.org/design/hvac.php

More by Carl Ian Graham, PE Steven Winter Associates Design Guidance Related Resource Pages Print Email INTRODUCTION Heating, ventilating, and air-conditioning (HVAC systems) account for 39% of the energy used in commercial buildings in the United States. Consequently, almost any business or government agency has the potential to realize significant savings by improving its control of HVAC operations and improving the efficiency of the system it uses. The use of high performance HVAC equipment can result in considerable energy, emissions, and cost savings (10%-40%). Whole building design coupled with an "extended comfort zone" can produce much greater savings (40%-70%). Extended comfort includes employing concepts such as providing warmer, but drier air using desiccant dehumidification in summer, or cooler air with warmer windows and warmer walls in winter. In addition, high-performance HVAC can provide increased user thermal comfort , and contribute to improved indoor environmental quality (IEQ). Given the range and complexity of the subject, this information should be viewed as only a starting point to access information from the many trade associations, agencies, and manufacturers linked throughout the text.
