considers both the daylighting and the artificial lighting of a modern
office building, to indicate both methods of computer calculation and
physical modelling.
EXAMPLE 1
The report which follows is a report on the daylight and artificial lighting
of offices for Wessex Water Operations centre in Bath for which the
architects were Bennetts Associates. The report is included by the
courtesy of Buro Happold, who were the structural, civil and building
services engineers for the building.
NATURAL LIGHTING
The primary goal of the following daylight analysis is the evaluation of
the potential of the design to provide appropriate levels of natural
illumination.
Two methods of calculation are applied:
Method 1. Artificial sky
Method 2. Computer modellingMethod 1. Artificial sky
The artificial sky at Bath University School of Architecture was utilized to
carry out a number of daylight tests on building sections. The artificial
sky at the university conforms to the standard CIE overcast sky scaled to
produce a variable 10,000 lux sky at model roof level. The tests were
