Heat Loss Calculations (and Heat Gain Calculations) offer assistance at the design stage of a project to ensure that occupier comfort is maximised and optimised. These calculations are part of the initial phase of construction during the design of the heating and cooling systems. HRS Services can offer Heat Loss and Heat Gain Calculations via our sister company Stroma Tech.

How can a dwelling lose heat?

There are a number of areas to consider where heat flows can be lost in a dwelling, including:

  • Heat loss through floors, walls, ceilings, windows, doors and penetrations
  • Heat loss via cracks in the building envelope
  • Deliberate heat loss via fans and dryers
  • Warm water heat loss via drains, sewers and drainage tanks
  • Gaseous heat loss via a flue

Heating Load Calculations

These calculations include conduction, convection, radiation and inter-zone energy transfer. All heating load calculations are based on a steady-state scenario which allows for internal set-point and external ambient temperatures. In order to accurately represent building start-up conditions the calculations will ignore thermal gains from solar radiation and internal activities.

Cooling Load Calculations

These calculations include casual, occupancy and solar gains effects. The cooling load calculations are based on the CIBSE admittance method. Our simulations repeat over the course of several days in order to allow convergence at the average peak conditions. This considers the same enery transfer process as a heating load assessment.

What is the result?

By undertaking heat loss and heat gain calculations, designers will be provided with a hierarchy of areas for plant size reduction, based on an explanation of each heat gain component.
