Passivent’s mixed-mode cooling system can help a building achieve a Class A Energy Performance Certificate, based on experience of real-life projects.

Retailers ASDA and Tesco make extensive use of Alldales variable-speed drives in air-handling systems. ASDA has installed drives in 77 stores as one of its measures to cut emissions by 20% by 2012. Following a 43% reduction in energy used by fans in air-handling systems in its stores in the south of England, Tesco retrofitted drives in over 350 larger stores.

Ray Edwards shares his experiences of huge and extremely cost-effective energy-saving potential of variable speed drives for fans and pumps.

Because many forms of renewable and recovered energy are not necessarily available when they are most required, thermal storage has a vital role to play in realising building-services systems that are both energy and cost efficient. This thermal store from Capito can accept energy from a variety of sources.

The importance of thermal storage

David Whitfield explores the central role that multi-energy thermal storage has to play in the design and delivery of an energy and cost efficient building system.

A ground-source heat-pump system at Mitsubishi Electric’s headquarters at Hatfield is linked to closed-loop coils laid in trenches to extract energy from the ground and help the system perform over 300% more efficiently than a traditional chiller/boiler combination.

While you cannot avoid using energy in the built environment, it is perfectly possible to take control of those energy costs — and benefit the environment into the bargain. Philip Ord looks at the potential of heat-pump VRF systems — and explains the significance of the headline.

The benefits of Endurance lighting fittings from Chalmor to reduce energy and maintenance costs have been exploited in this new facility of Robert Wiseman Dairies.

To help achieve the energy efficiency and reduced overall cost of ownership required by Robert Wiseman Dairies for its new £68 million production site in Bridgewater, consulting engineers AE Robb & Associate specified Chalmor’s long-life, energy-efficient Endurance lighting fittings in the cleaning-in-production (CIP) room.

As part of a sustainable solution for the refurbishment of the Strand Building of King’s College London, nearly a kilometre of active chilled beams with integrated lighting have been installed.

How chilled beams help improve the energy efficiency of buildings
