Kalwall translucent cladding has transformed the newly completed 4,200 square metre extension at Indiana’s South Bend Regional Airport. Designed by architects Ken Herceg and Associates, the new terminal comprises five gates, restaurants, gift shops and break-out areas all housed under an architecturally exposed, steel-framed barrel vault structure that simulates the structure of an aircraft wing. This is covered with a curved Kalwall Skyroof 10 metres wide and 180 metres long.
As passengers exit the TSA screening area, they are presented with unimpeded views across the runways. The Kalwall system enhances simplicity by doing away with the need for blinds, curtains or solar control. Even on cloudy days, the interior will be flooded with natural daylight, which means less artificial lighting and reduced energy costs. The standard Kalwall 70mm thick panel offers insulation up to 0.28W/m2K – equivalent to a cavity filled brick wall, whilst still allowing for up to 15 per cent visible light transmittance.
The architects made good use of Kalwall’s free daylight modelling service on this project. Daylight Modelling is the way to calculate the most effective daylighting for any type of building. It is calculated using five years’ worth of real world weather files at the exact location of the building together with information on day, time, position and weather patterns. This generates an in-depth report on interior lux levels, a glare pattern analysis and radiance Illuminance – a snapshot of the ambient lux level (light) at any given time on daylight penetration at any time of the day or on any day in the year.
