BARRATT HOMES CASE STUDY KNX KIT LIST: Concierge/Lobby Area: • Gira Power Supply and IP router • Theben Universal dimmer • Gira 1-10V dimming actuator • Gira DALI gateway • Intesis Gateway KNX/Mitsubishi Show Apartment: buyer, allowing them to personalise the level of technology and integration to suit their lifestyle and interior design preferences. They can easily choose to add different control elements and change functionality within their apartment, adjust finishes and designs of the push-button switches and, once broadband connected, add remote control and operation of the various technologies within the apartment. Inside track Once inside the building, residents are immersed in the sense of refined luxury which typifies Great Minster House. Using a touch screen, the concierge can automatically control light levels and temperature over KNX, and also adjust volume and select tracks to breathe background music through invisible ceiling speakers into the opulent lobby space. Here, KNX controlled high capacity Theben universal dimmers, providing crucial control over the LED lighting to ensure maximum efficiency is achieved, whilst also creating a stunning visual effect. When entering the show apartment, owners can activate a ‘welcome home’ function, triggering an initial lighting scene in each main living area, alongside the automatic playback of music. This function is mirrored by the ‘leaving’ action, implemented by a push-button keypad sensor next to the front door. Design Innovation selected KNX technology from five different manufacturers. Design Innovation has given the occupants in the show apartment access to three zones of audio. • Gira Power Supply and IP router • Gira Universal dimming actuators • Gira switch actuator • Gira heating actuator • Gira push-button sensor 3 with integral thermostat • ABB 1-10V dimming actuator • Theben universal dimming actuator with boost module • Theben Sphinx motion sensors • Intesis Gateway KNX/Mitsubishi • Loxone miniserver All the ABB and Theben controlled lighting in the apartment switches off progressively from back to front, allowing any guests within the property to leave safely. These lighting scenes can be personalised to suit the individual’s lifestyle and taste. At night, cove lighting in the bathroom and toilet areas is automatically activated by discreetly located Theben Sphinx motion sensors for complete ease of use. Homeowners also have the ability to set up their own domestic hot water (DHW), towel rail and heating and cooling schedule over an Android tablet that connects to the apartment’s KNX enabled server. Using the keypads, they can boost the short term operation of these systems as well as adjust the mechanical ventilation in different rooms in the apartment. Design Innovation has ensured that the heating and cooling system will not operate in conflict to optimise comfort and energy efficiency still further. All control functions within the show home are also accessible via a smartphone or tablet when inside the apartment. With full integration to the AV system, Design Innovation has given the occupants in the show apartment access to three zones of audio, via installed invisible speakers in dining room, living room and bedroom. The system provides music streaming over airplay and Bluetooth and the facility to connect music via a line-in to the system. ‘The KNX open standard allowed us to bring together the right equipment from a choice of different KNX manufacturers to provide the best solution for this project,’ comments Nick Gale, managing director at Design Innovation. ‘The show apartment uses multiple manufacturers all working seamlessly together, and offers the flexibility of easy AV integration and end user customisation. Great Minster House is a great demonstration of the capabilities of KNX and its huge potential as an effective and versatile solution within multidwelling unit developments.’ KNX is a simple system for intelligent electrical installation networking. A KNX bus cable combines devices and systems and new functions can be easily added in the future as the needs of occupants change and extra functionality is required. KNX products are used to build intelligent integrated building control solutions for residential and commercial applications. As a result, owners, residents, or managers of these properties have control over the everyday working or living environment. This can cover all building services such as heating, ventilation, air conditioning, lighting, security and metering as well as the operation of blinds, electrical appliances, windows, facades, AV/sound systems and many other functions. 7 06-7 Case Study – KNX.indd 7 14/06/2016 12:20
