The prime requirement in respect of the indoor climate in a building is that room temperature should be at a comfortable level, regardless of the weather conditions outside. As soon as the ambient temperature is lower than the indoor temperature, heat flows out from the building through its boundary surfaces (the building envelope). At the same time, the building also loses heat through air infiltration, i.e. the inward leakage of outdoor air into the building through gaps and cavities in walls, roofs, doors and windows. Bearing in mind the fact that the indoor temperature in most buildings is maintained at a little over 65°F, this means, throughout most of the year, the building is losing heat to its surroundings.
This 5-hour course, discusses the stepwise procedure to determine the rate of heat loss through building elements using a process called heat loss calculation. You will learn how to extrapolate your calculation of a maximum hourly rate into an annual energy usage rate. You will also learn some useful tips on saving heating energy. The course includes one sample example for better understanding of the concept.
Learning Objectives
Upon completion of this course, participants will be able to:
- Describe the factors that affect winter comfort.
- Apply the basic heat-loss equation to building elements, including walls, roofs, and glazing.
- Calculate heat loss through floor slabs and basements using the applicable basic equation.
- Explain the concept of degree days and how degree days are used to estimate annual heat loss.
- Distinguish among the three basic modes of heat transfer: conduction, convection, and radiation.
- Calculate the series resistance and U-values of a composite wall.
- Determine infiltration and ventilation airflow rates.
- Explain the overall heat-transfer coefficient (U-value) and its relationship to thermal resistance (R-value).
- Apply the basic heat-loss equation to ventilation and infiltration.
- Distinguish among k-values, C-values, R-values, and U-values.
