Intended learning outcomes

Upon completing the course the student should be aware of the effects of heating and ventilation on indoor air quality and thermal comfort, as well as the implications on energy management in the built environment. Furthermore students should become familiar with the concept of the environmental building assessment and various assessment schemes and tools commercially available.

Course main content

The objective of this course is to provide a thorough understanding of how ventilation and heating/cooling affect thermal comfort, and air quality indoors, and how this, in turn reflects on energy management in the built environment. Thermal comfort and space-conditioning are analysed against the background of human physiological requirements. Different methods for evaluating thermal comfort and indoor climate are presented as applicable in different indoor environments (industries, offices, dwellings, etc.). Factors affecting air quality are analysed. Gaseous and particulate indoor air pollutants are discussed with regard to acceptable concentrations, health effects, existing regulations/standards and control measures. Ventilation demand and ventilation effectiveness are discussed as determined by requirements of pollutant and heat removal in different indoor environments. Methods for estimating/calculating the energy flows required for achieving specific levels of thermal comfort and air quality are analysed as relevant to energy management in the built environment. The influence of architectural aspects is presented and analysed. The concept of environmental building assessment is presented together with assessment schemes and tools commercially available. Occupant behaviour is discussed as relevant to the possibilities of enhancing energy efficiency. A study visit to a relevant site/facility is arranged.
