Balfour Beatty WorkPlace had a requirement to renovate an office to be used as a meeting suite for the Board and customers. Abtec were approached to recommend a combined Lighting and HVAC environmental control system. KNX was selected as the field level control system and combined with Siemens Presence Sensors, RXB Fan Coil Unit Controllers and DALI Gateways.
Lighting was completely DALI based and provides automatic emergency testing as well as fault feedback. Lighting was daylight linked in areas with natural light and preset levels of dimming were employed where there was no natural light. Scenes are supported via a colour touch panel in main meeting room. This panel also supports HVAC settings for the whole floor as well as lighting dimming presets.
The client realised substantial energy savings through room and floor occupancy control for both lighting and HVAC. Even when occupied, energy is saved through daylight linking and preset dimming. In corridor and toilet areas, dimming presets are as low as 25% brightness.
