Comfort delivered to cosmetics supplier
Advertisement
Ethical cosmetics retailer Lush is now able to deliver energy efficient air conditioning to employees at its new office space in Poole, Dorset, thanks to the installation of Mitsubishi Electric’s City Multi VRF heat recovery system.
Lush expanded its business with a new unit at Dolphin Quays, a complex made up of both residential apartments and office spaces. The units came equipped with running water and electricity, but Lush needed comforts for employees, including air conditioning, to be installed.
The solution came in the form of 12 ceiling-suspended City Multi VRF indoor units and one floor-positioned unit, installed by Modern Facilities Services, a Mitsubishi Electric Accredited Installer.
The system is able to move excess heat, generated from an area which is being cooled, to other parts of the building which need heating, helping to deliver the high levels of efficiency that Lush required. The City Multi system also offers good energy-saving performance, advanced control system and flexibility of design for specifiers and installers. The long pipe-runs and ability to connect up to 50 indoor units to one outdoor condenser means that it offers advanced, controllable energy efficient comfort to suit almost any building.
Krystal James, project coordinator at Lush, said: “We wanted a system that would create a pleasant working environment for our staff, while fitting comfortably into the office environment. We also wanted to make sure we avoided any draughts for our employees.”
Two Lossnay Mechanical Ventilation with Heat Recovery (MVHR) units were also installed at the site in order to remove stale air from the office. The units operate by capturing up to 80 per cent of the temperature of the outgoing air, meaning less energy is needed to bring fresh outdoor air up to the indoor temperature. ONLINE ENQUIRY 106
A burner upgrade project at a prestigious visitor attraction in Edinburgh involved the replacement of the existing 25-year-old burners with Riello ultra-low nitrogen oxides (NOx) premix burners.
The Riello RX1800 1.8MW premix burners, commissioned by contractor T-Squared, have shown low NOx levels of just 9-10ppm (around 20mg/kWh) throughout the modulation range. This is around half the 40mg/kWh maximum required by some local authorities and also below the Building Research Establishment Environmental Assessment Method (BREEAM) criteria of 24mg/ kWh. Consequently, the burner upgrade enabled the ageing cast-iron sectional boilers to comply with current and anticipated NOx regulations, as well as improve energy efficiency – thereby extending the life of the boilers.
“The client was very keen to improve energy efficiency and meet future standards for NOx emissions, while retaining the existing boilers for a few more years,” explained T-Squared’s Garry Wallace. “We therefore suggested replacing the older burners to achieve better turndown and temperature control with improved efficiency and reduced NOx emissions. We considered several manufacturers and selected Riello on the basis of product quality and performance, technical knowledge and customer support.

Boilers in residential care home upgrade
Three XL140 boilers from ATAG Commercial have been installed at Norman Lodge, a residential care home in Bradford, as part of a major renovation project – which included refurbishing the heating system. The project saw the boilers fitted alongside a CHP unit, independent water heaters and calorifiers, replacing the building’s original, 25-year old heating system. The installation was completed in February 2019.
Norman Lodge is managed by City of Bradford Metropolitan District Council. The council has long been a customer of ATAG Commercial, which has resulted in the company’s boilers being installed in a variety of locations throughout the Yorkshire area.
Terry Nichols, mechanical works officer at City of Bradford Metropolitan District Council, explained: “The previous plant room contained a lot of steel, which was replaced by modern, carbon fittings. New boiler housing and heating circuits were also fitted alongside the XL boilers. The new heating system will ensure care home residents are kept nice and warm, while we know from past experience that using ATAG Commercial boilers can reduce energy bills by up to a third.” ONLINE ENQUIRY 105
Controls partnership for clothing supplier
US based clothing and outdoor recreation equipment specialist, L.L.Bean, is benefitting from a long-term partnership with Trend Control Systems.
The company’s 18,600m2 flagship store is located on the original site where Leonwood Bean opened his first shop and today the store draws close to 3m visitors each year. The seven-acre retail campus is also home to L.L.Bean’s Hunting & Fishing Store, Bike, Boat & Ski Store, and Home Store. The company also has 27 retail stores outside of Maine, as well as 10 outlets.
In addition to its retail sites, L.L.Bean’s US operation comprises a number of office buildings, call centres, manufacturing and distribution sites, and a data centre. Tom Leslie, heating, ventilation and air conditioning supervisor at L.L.Bean, comments: “With multiple locations it’s important to be able to monitor, manage and reduce energy use and ensure that each building is operating optimally, while keeping customers, staff and visitors comfortable. We have worked closely with FMC Technologies for over 15 years to install and maintain our BEMS infrastructure, with a goal of reduced energy use.”
Dave Snowdon, engineering manager and vice president atFMC Technologies, adds: “We implement technology that reduces operating expenses, increases productivity and provides a safe, comfortable working environment. Our long-standing relationship with L.L.Bean began when we were asked to integrate third party building control devices with Trend BEMS technology in the company’s data centre, and since then we have rolled out Trend equipment across 25 locations.”
Having visibility into energy use in real time is vital to Tom Leslie and his team. To meet this requirement L.L.Bean’s BEMS is configured around Trend’s pioneering IQ VISION, which integrates Trend controllers, third party smart devices and internet protocols into a centralised software platform that offers the ability to highlight and investigate energy use.
