You will develop an understanding of heat transfer as it applies to buildings and the various factors that must be considered when calculating the heating and cooling loads of a building. After completing the course, you should know:

• How to use a simple heat loss calculation procedure.
• How to find and use local climate data.
• The thermal properties of building materials.
• The effects of air infiltration and ventilation.
• The basic concepts and methods to determine cooling loads.
• The effects of windows, walls, roofs and partitions on loads.
• The basic types of internal loads.
• How to use the CLTD Method.
• How to use the Transfer Function Method

• Heat Transfer and Load Calculation -- Conduction; convection; radiation; thermal capacitance; and sensible and latent heat transfer.
• Simple Heat Loss Calculation Procedure - The basic process; example building; and useful comments.
• Temperature Design Conditions and Weather Data - Inside and outside design conditions; winter outdoor design temperature; wind and annual extremes data; summer outdoor design conditions; and other sources of climatic information.
• Thermal Properties of Materials - Building material properties; U-factors for non-uniform sections; surface resistance and dead-air spaces; and thermal performance among alternatives.
• Heat Transfer Through Walls, Roofs and Floors - Building description; zoning the design; unheated spaces; slab-on-grade; basement; crawlspace; dormers, gables and overhangs; and building summary.
• Infiltration and Ventilation - Infiltration sources; air change method; effective leakage area method; ventilation; and humidification and moisture control.
• Cooling Load Calculations - Heat flow rates; initial design consideration; and calculation methods.
• Air-Conditioning Loads on Walls, Roofs and Partitions - Sol-air temperatures; CLTD for roofs; CLTD for walls; interior partitions; and sample problem.
• Cooling Loads from Windows - Window gains by conduction; solar heat gains; internal and external shading devices; and example calculations.
• Internal Loads - Lighting; power; appliances; people; cooling system gains; and examples.
• Example Heating and Cooling Load Calculation - Sample problem definition; initial data collection and assumptions; heating load; and cooling load.
• Transfer Function Method - Heat gain by conduction through exterior walls and roofs; conversion of cooling load from heat gain; and use of room transfer functions.
