LIGHTING PROJECT
Smart lighting upgrade improves energy use across government sites
WHITECROFT LIGHTING has completed a large-scale lighting upgrade across 129 Department for Work & Pensions (DWP) locations throughout the UK. The project involved replacing older lighting systems with LED luminaires and smart controls, aiming to reduce energy consumption and carbon emissions within the department’s buildings, including Job and Health Assessment Centres and offi ce spaces.
The installation featured Whitecroft’s
Organic Response smart lighting system, which uses daylight sensors to adjust light levels automatically according to natural light availability. This system also includes automated occupancy sensors, eliminating the need for manual switches and reducing
energy waste in unoccupied areas. These features are designed to extend the lifespan of lighting fi xtures and reduce maintenance requirements. The upgrade incorporated
approximately 54,300 products and was delivered in partnership with facilities management provider Mitie over a two-year period. Installation was carefully scheduled outside normal working hours to minimise disruption. The new lighting system supports
the DWP’s target to reduce carbon emissions by 45% and complies with evolving energy legislation. It also enables cloud-based monitoring and energy heat mapping to track and optimise building performance
remotely. ■

The Novotel Edinburgh Centre is the site of the fi rst UK installation of Toshiba Universal Smart X (USX) Edge modular heat pump from CARRIER SOLUTIONS. The project involved installing two 150kW air source heat pumps, providing a combined capacity of 300kW, designed to fi t within limited rooftop space. The installation took place in July 2024, with Carrier working alongside contractors AlterTherm Group Ltd. The system’s modular
and compact design allowed for installation in a constrained area, with an X-frame chassis that eased positioning on the rooftop. The units feature advanced compressor technology and a pulse width modulation converter to improve energy effi ciency
and reduce power losses. They operate using R32 refrigerant, which has a lower global warming potential compared to older refrigerants. Remote monitoring
is available via wireless LAN, enabling real-time control and optimisation by hotel staff and service engineers. The system includes built-in redundancy through independent circuits in each unit to maintain
operation in case of failure. Careful planning of
delivery and installation ensured minimal disruption to hotel operations, with a crane lift completed overnight requiring temporary road closures. The new heat pumps have replaced an older system, off ering improved environmental performance and consistent comfort for
guests and staff . ■

UNDERFLOOR HEATING
Historic castle modernised with renewable heating system
Rosslyn Castle, near Edinburgh, has been updated with a modern heating system supplied by REHAU as part of a £4 million restoration project focused on improving energy effi ciency and reducing carbon emissions. The castle, a Category A listed building that has functioned as holiday accommodation since 1985, now uses six air source heat pumps installed in its vaults to minimise noise and benefi t from the thermal mass of the structure. Heat and hot water are distributed
via a combination of underfl oor heating and radiator circuits. Rehau provided the underfl oor heating system, selected for its ability to deliver even heat in large open spaces such as the castle’s great hall without aff ecting its historic appearance. Installation required carefully lifting and storing original oak fl oorboards to install diff usion plates and pipework before restoring the fl ooring. For radiator circuits, Rehau’s fl exible
multilayer composite pipe was used, allowing installation within the castle’s narrow spaces while avoiding hot works that could damage the listed building.

Solar to reduce energy bills and carbon emissions for school network
Wellspring Academy Trust has completed the fi rst of six planned solar PV installations across its school network, marking a signifi cant step toward reducing energy costs and embedding sustainability into everyday learning. The fi rst system, installed at
Springwell Alternative Academy Grantham in Lincolnshire by renewable energy specialists GEO GREEN POWER, was completed over the Easter break. Five further installations will follow
The system is expected to reduce heat and hot water consumption by 67% compared to the previous system, supporting Rosslyn Castle’s transition towards net zero energy use while
preserving its historic fabric. ■

over the summer at Ebor Gardens Primary School in Collingham and four Leeds schools including Green Meadows Academy, Victoria Primary Academy, Penny Field School, and Springwell East Academy, the largest site in the project. Once all six systems are live, the combined installations will generate
more than 341,650kWh of clean energy annually, cutting 85 tonnes of CO₂ emissions and saving the Trust an estimated £92k per year. These savings will be reinvested
into classroom resources and staff development, directly benefi ting students and teachers. “Energy costs directly aff ect our
school budgets, so investing in solar power means we can channel those savings into enriching the education we provide,” says Mark Marples, project manager. “More importantly, our commitment to sustainable practices off ers students a real-world example of renewable energy in action, helping them understand the science behind solar power and the importance of
sustainability.” ■
