Southwark council's energy efficient lighting retrofit


Almost ten years after the original installation, ZUMTOBEL and its sister brand Thorn have completed an office retrofit of Southwark Council offices' lighting, with energy and carbon emission reduction at the forefront. At the council’s Queens Road facility,


INFRARED HEATING


Keeping church congregation in comfort Despite initial budget concerns, the


Infrared heating specialist SHADOW INDUSTRIAL has partnered with St. Helen’s Chapel in Colchester, Essex, to install a low-carbon heating system. The project involved the installation of 14 ceiling- hung and wall-mounted heaters, along with 16 controllers, providing a warm and sustainable environment for worshipers. The church, facing the challenge of heating large, poorly insulated, and historic buildings, turned to shortwave infrared heating technology. This technology emits focused radiant heat, warming individuals directly rather than the surrounding air. It is easy to install, has minimal impact on the structure, and consumes low energy. The system signifi cantly improved comfort, allowing congregants to remove coats during services.

Factory achieves energy savings through solar PV


Vacuum technology manufacturer KURT J. LESKERCOMPANY (KJLC) has installed solar photovoltaic panels with a combined capacity of 100.04 kWp on one of its factory sites in Hastings. The installation is expected to save the company £25,687 in energy costs annually. Advantage Utilities, a company working


with KJLC since 2016, helped secure favourable energy and gas contracts and achieve Scope 1 and 2 emissions certification. The solar PV installation, facilitated by Advantage Utilities in June 2023, will result in estimated savings of £513,265 over the 25-year lifetime of the system, bringing the lifetime cost of electricity (LCoE) down to 5p/kWh. Commenting on the recent installation, Simon Mansbridge, MD at Kurt J. Lesker Company, says: “We’re incredibly pleased with the results of our recent installation. We’ve made energy savings of 85,624 kWh per year, meaning we now produce a third of our on-site energy needs at one of our sites

infrared heating solution proved to be more cost-eff ective than traditional alternatives, resulting in an 80% upfront saving compared to underfl oor heating. Shadow Industrial’s expertise in preserving heritage buildings was highly praised by the church. Commenting on the project, Shadow Industrial’s founder, Steve Levy, says: “We are deeply committed to the preservation and longevity of heritage buildings. With a focus on comfort, we have successfully executed numerous heating projects with this in mind, of which St. Helen’s Chapel is the latest. It’s such an important local landmark and it was great to be able to provide a solution that benefits all those


who work, volunteer, and pray here.”■ www.shadowindustrial.co.uk


HEAT INTERFACE UNITS Sustainable and efficient heating in


12-storey residential tower management also opted to install smart heating controls, which can be accessed through a smartphone or tablet app, enabling remote control of heating and potential energy savings. Taconova conducted testing on each


in Hastings, with potential exports back to the grid also enabling energy savings. Advantage Utilities’ collaborative and respectful approach enabled us to deepen our relationship, having previously only focused on energy contracts." Dr. James Crosby-Wrigely, head of sustainability at Advantage Utilities, adds: “Kurt J. Lesker’s installation is a prime example of what’s possible through the latest solar PV technology - now one of the cheapest and greenest solutions for businesses. The reduction in their carbon footprint will be dramatic, with a carbon benefit relative to UK standard grid consumption of 20,409kg/20.5 tonnes of


CO₂ in the first year." ■ www.lesker.com


A £37 million residential development in Sheffield has implemented TACONOVA'S Heat Interface Units (HIUs) to achieve sustainable and efficient heating. The Ironworks, developed by Rise Homes, consists of a 12-storey building with 229 furnished apartments. Each unit is connected to a communal biomass boiler-powered heating system. Water heated by the basement biomass boiler circulates through the building's risers and into the HIU in each apartment, ensuring efficient heating and domestic hot water provision. The TacoTherm H 3000E HIU,


specifically designed for multi-storey residential buildings, is installed in each flat. It is an electronically controlled, compact, all-in-one unit that offers indirect heat transfer for heating and domestic hot water. The HIU features a smart meter for remote monitoring and analysis of heat consumption, allowing for increased efficiency and quick identification of any faults or inefficiencies. The Ironworks


HIU to ensure proper performance and compliance with set design parameters. The company will continue to monitor and improve the heating system throughout its lifetime, providing annual servicing of the HIUs. Future plans include joining the Sheffield City District Heating Network, which would allow the Ironworks to utilise waste heat from the city's incinerator, further enhancing the building's sustainability and potentially reducing energy bills for residents. All the HIUs had to be supplied, installed, and commissioned within a three-month window. Taconova delivered 50 HIUs per week, and the contractor installed them in the utility cupboard of


each apartment. ■ www.taconova.com


EIBI | MARCH 2024


the existing lighting installation mainly consisted of Zumtobel's Light Fields T16 luminaires, which was upgraded to LED lighting. The retrofit solution included Light Fields III recessed and suspended luminaires with custom infill panels, Panos infinity downlights in various sizes, Mirel recessed luminaires for wall washing, Comsign emergency signage, Thorn Katona wall luminaires for stairwells, Thorn's Aquaforce dust and moisture proof luminaires for plant rooms, and


Thorn Piazza pathway luminaires for the exterior.


Southwark Council also wanted to


upgrade its lighting control system to enable them to connect to the building from a remote site to review performance and errors, reducing efforts in maintenance. The new luminaires consume a third of


the power of the original scheme. Coupled with a new control system with good occupancy control which is easy to adapt by the building manager, the efficiency of the lighting installation has been greatly


improved. ■ www.zumtobel.com
