| Module Description: |
This module looks at all the components that contribute to heat gain in a building. Quantification of solar gain and internal gain is undertaken. Coling loads are calculated using dynamic modelling.Methodolgies such as shading and use of exposed thermal mass to minimise the cooling load are explored. |
| Learning Outcomes |
| On successful completion of this module the learner will be able to: |
| LO1 |
Analyse the components of heat gain that contribute to building cooling load. |
| LO2 |
Select and apply an appropriate form of modelling for cooling load calculations |
| LO3 |
Apply dynamic analysis in the calculation of the peak cooling loads and maximum summer internal temperatures of a building. |
| LO4 |
Propose methodologies to reduce peak cooling load. |

Module Recommendations
This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named CIT module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s). |
| No recommendations listed |
Incompatible Modules
These are modules which have learning outcomes that are too similar to the learning outcomes of this module. You may not earn additional credit for the same learning and therefore you may not enrol in this module if you have successfully completed any modules in the incompatible list. |

Module Content & Assessment
| Indicative Content |
|
Modelling
Description of steady state and dynamic models for cooling load calculations, applicability and limitation of models. Properties of structures that affect the dynamic analysis such as thermal transmittance, thermal admittance, time lag, decrement factor and response factor.
|
|
Solar Gains
Calculation of solar gain through glazing, solar irradiance, altitude and azimuth angles, estimation of solar cooling loads using empirical tables.
|
|
Internal gains
Determination of lighting load due to lux levels and lamp type, estimation of occupation rates and associated sensible and latent heat gains, assessment of loads from business machines, laboratory equipment etc.
Heat loads form industrial equipment.
|
|
Cooling load calculations
Use of dynamic model equations (CIBSE admittance proceedure) to calculate the summer cooling load and peak summer internal temperatures in a building.
|
|
Load minimisation strategies
External shading devices, glazing treatment, internal binds, reduction in glazing area, thermal mass, night cooling.
