Technology and older (parcularly ‘listed’) architecture can be uncomfortable companions. Lighng Controls Ltd has always been known for its design of discreet lighng components incorporated within their control systems
Continuing this theme, Lighting Controls has introduced three devices designed to make the lives of designers and installers of lighting systems simpler, and result in lighting systems that are more aesthetically pleasing.
Two new presence detectors have been introduced that can be mounted in very small cavities or even within a luminaire. One detector uses microwave technology for the detection of movement, and is ideal where ambient temperatures can vary. Such variations can play tricks with traditional infrared detectors, which are sensitive to temperature changes as well as motion. The other is a sub-miniature PIR (passive infrared sensor) that uses traditional

technology but, at only 16mm diameter, is visually much less obtrusive than devices previously available.
The third innovation that continues the theme of discreetness, is a very thin DALI switch, which can fit behind an architectural switch in a 28mm pattress box. This solves the problem of easily incorporating antique or architectural switches into a DALI lighting control network. All these new components are designed to work with, and are backwards compatible with, Lighting Controls Ltd’s EcoLUX lighting control system. These systems incorporate movement detection and daylight dimming, and more complex systems are
typically controlled by the web- based EcoLUX Graphical Interface.

Manchester Royal Infirmary (MRI) can claim many medical breakthroughs and can also boast pioneering energy ecient lighng throughout their estate
Luceco, A C Electrical (North) and the Estates and Facilities Directorate at the MRI have worked together to reduce energy consumed by old lighting technology, replacing these fittings with cost effective LED luminaires from Luceco.
Richard Horton said “An example would be a typical hospital corridor. We removed 120W wall washers and replaced them with LED asymmetric LuxPanels from Luceco running at 44W, creating substantial savings. However, using LiteIP, we have reduced the energy consumption of the 44W luminaires to provide an additional 95 per cent saving by utilising available daylight. The corridor was lit 24 hours a day, seven days a week, it now operates at five per cent for the majority of the burning hours when personnel are not present, illuminating to 100 per cent when traffic is detected. Whilst we realise daylight light harvesting will reduce during the winter, the impact on energy consumption along with the PIR control has created massive energy savings.” LiteIP has assisted with these savings and has been included in several new projects at the MRI. LiteIP provides a flexible, intelligent wireless lighting system requiring no complicated electrical installation and no limit to the number of luminaires
that can be controlled. Each wireless luminaire is programmed to operate using drag and drop menus within LiteIP software. Changes to individual luminaire operation, to improve control, can be made without the need to alter any wiring. Furthermore, emergency lighting tests can be run automatically, with monitoring email alerts and reports generated avoiding the need for manual recording of results.
The lighting installation is also simple and can be completed as if no lighting controls are required, each luminaire needs only Live, Earth and Neutral, no expensive control cables are needed. This is followed by a commissioning engineer setting up the system on-site, applying settings and grouping luminaires as required. LiteIP is compatible with all driver types including DSI, DALI and 1-10 V. As well as presence and daylight detection, other features include energy monitoring and reporting.

BMS and process control technology from Priva is helping Queen Ethelburga’s Collegiate improve the eciency and monitoring of its new boiler house, Priva’s Blue ID system
Due to the age of Queen Ethelburga’s Collegiate, changes to the fabric and infrastructure are inevitable, particularly when it comes to heating and water services. CambridgeHOK, a long-time Priva partner and installer, was invited to devise a system capable of controlling the school’s onsite sewage treatment systems.
“One major problem was that the school originally had multiple, smaller boiler houses that had to be individually monitored and maintained,” explains Duncan Grant, project lead at Cambridge-HOK. The existing control systems were from different manufacturers and, over time, everything was replaced with Priva technology.
Queen Ethelburga’s had installed efficient, duel- fuel boilers that run on gas and oil in the new ‘KEB boiler house’. CambridgeHOK designed and manufactured a control panel that incorporates Priva BMS controls to supervise and control the boiler house equipment, overseeing domestic hot water,
water distribution, purification and UV sterilisation. “We developed bespoke software programs to link the existing systems to the new control panel,” says Grant. “This means that all Priva systems on site can communicate effectively, passing on the heating and hot water demands of the campus to the new boiler house.”
The new central system represents a much easier solution for such a large site with many different heating demands.
An important part of the technology’s process control capability is protecting against legionella. The bacteria do not survive above 60°C, so the Priva technology runs the hot water tanks to 65°C and holds it for a prescribed time before distribution. The Priva equipment also monitors the levels in eight underground tanks that hold fuel for the boilers and red diesel for other on-site uses.

Leading Brish fan manufacturer Vent Axia has supplied two Sennel Mulvent H central extract units to a refurbished tenement property in Edinburgh New Town
The former basement store has been redeveloped and extended to create a luxury five-bedroom home and has been named as one of the ‘100 best homes in Scotland since 2000’ according to the Royal Incorporation of Architects in Scotland.
The project, led by Capital A Architecture, involved an extensive redesign and extension that created a more open plan living area, split over two levels. The rear garden is steep and the redesigned garden room has a lowered floor level to connect to the garden with as few steps as possible. The seven-month build included installation of Vent-Axia’s Sentinel Multivent H continuous mechanical extract ventilation (MEV) units which provided ventilation to the kitchen, bathroom and three en-suite areas.
A continuous running MEV system, the Sentinel Multivent H was ideal for the project since its integral humidity sensor is designed for the simultaneous ventilation of separate areas in the home. The integral humidity sensor increases fan speed in proportion to relative humidity levels, saving energy and reducing noise. By reducing

moisture levels and removing pollutants in the air such as carbon dioxide, indoor air quality is much improved and helps to create a healthier living environment. Both energy efficiency and the Multivent’s humidity sensor were key drivers for the MEV system’s specification. Boasting energy efficient EC/DC motors the Multivent helps achieve carbon footprint reduction targets since the motors lose a third less energy to heat than a conventional AC motor. Meanwhile, the integral humidity sensor, which increases fan speed in proportion to relative humidity levels, also reacts to small but rapid increases in humidity, even if the normal trigger threshold is not reached. This unique feature ensures adequate ventilation, even for the smallest wet room. And its night time relative humidity increment setback feature suppresses nuisance tripping as humidity gradually increases with falling temperature. These options are ideal in this type of property that has low levels of natural ventilation.
