Cooling load is a calculation used in building design to determine how much heat needs to be removed to maintain a constant temperature. Factors such as humidity, equipment, and layout are considered to create an efficient heating and cooling system. Designers consider worst-case scenarios to ensure the system can handle extreme conditions. Balancing heating and cooling loads requires similar design characteristics, such as insulation and layout, to save energy in both hot and cold climates.
Cooling load is a calculation that determines how much heat must be removed from a structure to keep the temperature inside constant. It is one of the things considered during the design phase of a building or heating and cooling system, together with the heating load, is determining how much heat energy needs to be added to keep the temperature stable. The goal is to build a structure with maximum efficiency to reduce costs related to heating and cooling.
Numerous factors contribute to heat within a structure. One consideration is temperature measured directly versus temperature and humidity examined together. High humidity can make low temperatures feel warmer, and a building in humid conditions will have a higher cooling load, as more energy will be needed to make the space comfortable for the occupants. Humidity also plays a role in the heating load.
People, equipment and processes within a facility can generate heat, humidity and affect the cooling load. Buildings are not static spaces and their uses need to be considered when assessing heating and cooling needs. Similarly, buildings themselves can contribute to the trapping or release of heat energy. Doors, windows and layout of spaces can all play a role in indoor temperature, as can design elements such as curtains, screens for partial closure of areas and so on.
When considering cooling load, designers usually look at worst-case scenarios. By looking at temperature data for the region, they’ll sort through unusually high temperatures and humidity, and imagine what would happen inside if everything in a building worked at the same time, with a full complement of staff. This is designed to develop an extreme cooling load estimate, enabling the construction of a cooling system that can cope with such conditions. By designing for the most intense conditions, engineers can be confident that their heating and cooling systems will not fail under normal use.
Balancing the heating and cooling load for a facility often requires similar design characteristics. Things like better insulation can help buildings stay cool in the summer while also keeping them warm in the winter, for example, and considerations like layout can likewise save energy. This is useful in climates where there may be dramatic temperature swings, as the same general design features meet climate control needs in both hot and cold climates.
