DAYLIGHTING & VENTILATION

Developing strategies for better internal environments David Mowatt, Director of Lareine Engineering, discusses the dual roles of daylighting & ventilation in creating healthy and safe internal environments Every building, whatever its purpose, must provide a controlled internal environment that is protected from the variable and uncontrollable external climate. The requirements of the internal environment will depend on the intended use of the building and this will naturally determine the requirements for the building envelope. Generating and maintaining a controlled internal environment is a complex process and the design of the building envelope is an important factor in determining comfort levels

and safety of occupants within the building, as well as the energy performance of the building itself. Appropriate levels of daylight and fresh air are crucial to the success of a building and a balanced, holistic approach to design and specification of daylighting & ventilation systems will generally provide the best results. Common pitfalls of poor daylighting & ventilation design are: poor energy utilisation, inadequate control of internal temperatures, poor air quality, glare and very importantly, compromised safety of building

Residential apartment buildings ...can be greatly enhanced by introducing high levels of daylight to public areas. They also present specific challenges for ventilation system design, with many dividing internal walls and high demands for safety, privacy and security of individual units. 1. Louvred ventilators allow clean fresh air to be drawn in to replace stale air 2. Roof ventilation terminal to exhaust stale air and fumes 3. Central pyramid skylight delivers daylight to stairwell – with built-in AOV (automatic opening vent) panels for smoke ventilation is case of fire
