In your capacity as Civil Engineer with a specialism in energy and environmental design, you have been employed by an architect to give advice, at the early stages of building design, on the thermal perfor-mance of a proposed school.
Traditionally Ireland has followed UK standards in this field, so this assignment will be conducted us-ing easily accessible UK standards. UK schools are usually built without mechanical ventilation or cooling. However, the architect and client are concerned whether or not the environmental perfor-mance criteria for summer temperatures can be met without mechanical cooling in view of the den-sity of students in the classes and the increased use of computer equipment.
In the interests of cost and speed of construction a medium weight external fabric on a steel frame structure has been proposed (see Appendix). Due to concerns that acoustic requirements may be diffi-cult to satisfy, it has also been proposed to use a mineral tile false ceiling.
