Lighting

The daylighting is admitted through double-glazed polycarbonate barrel vaults, running the width of the hall in rows above each truss. There is one truss between each court. Sailcloth, suspended within the truss, diffuses the daylight.

Fluorescent luminaires - custom made linear versions of the Apollo Corsaire, are located in the bottom of the inverted triangle cross-section truss (apex). The light is mainly downwards, with a small proportion leaking up to the truss and surrounding ceiling. The lights were not mounted behind the sailcloth (as at Brune Park) as the efficiency of the lighting was affected by the reduction in light transmission.

Control is by manual switching with occupancy sensors. The light levels can be adjusted between 300 - 500 lux.

5.3.2 Lords Indoor Cricket School

Introduction

This sports hall is for the Lords Indoor Cricket School. It is therefore not of the normal design for a multi-use sports hall; instead being designed for one sport. The hall is still of interest, as it is daylit. It was designed by David Morley Architects, London, with Bryant Priest Newman. The lighting design was carried out by Max Fordham and Partners.

Construction

The roof and walls are painted an off-white colour and the floor is green, to simulate outdoor cricket conditions. See fig. 5.3.4 for a view of the interior.

Lighting

The hall is lit with artificial light and daylight, through a series of north facing rooflights. The rooflights, of clear double-glazed glass, are arranged so that they are parallel with the pitches. External louvres are provided.

The lighting was first estimated, then calculated and simulated. Lighting controls are manual, with daylight linking to control illuminance levels.

5.4 Proposed Daylit Sports Halls in Scotland

Besides the above examples of daylit sports halls there are also a selection of proposed halls which will feature daylighting. Two of these will be reviewed in the next report to identify cost/energy savings and benefits for a range of design scenarios.

5.3 English Daylit Sports Halls

5.3.1 Chipping Norton

Introduction

This hall is part of a development for a school. It is not yet built, but will be completed towards the end of 2001. The architects for the project are Fielden Clegg, of Bath. There has been significant modelling and calculation exercises for this hall, by the architects and Brian Ford. A 1:50 scale model was constructed to test the designs, see fig. 5.3.1.

Construction

The hall has a sheet metal roof, supported by a series of inverted triangular trusses. These trusses support the lighting and sailcloth diffusers. The roof is glazed above each truss with a barrel vaulted rooflight. See figs. 5.3.2 and 5.3.3 for elevations of the hall.
