heating, plumbing and ventilation Making the most
of energy sources SolarFlow from Alfa Laval is a tap water pre- heater designed to exploit energy from renewable sources such as solar panels, geothermal fields, heat pumps and even condensate recovery for domestic hot water production. SolarFlow was developed specifically to provide cost-effective domestic hot water to large structures such as apartment buildings, hospitals, hotels, retirement homes, nursing homes, schools, and sport centres. Intended principally as a pre-heater, SolarFlow must be combined with a conventional tap water heat source, which acts mostly as a top-up facility. In this way, the system prioritises the renewable energy source, keeping reliance on conventional energy to a minimum. Thanks to the fact that water in the primary tank is never heated by a boiler or electrical heater, the unit offers genuine energy savings. In addition, the configuration of the primary tank guarantees maximum energy delivery on demand. SolarFlow is the latest addition to the Alfa Laval range of Tap Water heating systems.

Calculating sustainable strategies
A unique software tool, to help architects and specifiers accurately and quickly assess the impact of natural daylighting on a building’s energy performance, has been launched by Passivent. The company has worked closely with leading software house Environmental Design Solutions Ltd (EDSL) to develop the utility- Passivent Sunscoop™ Builder, which complements the already proven Passivent Airscoop Builder tool for natural ventilation in buildings. Both tools are based on
substantial, recently-published research. Available as a free download from
www.passivent.com and
www.edsl.net, Passivent Sunscoop™ Builder enables users to model quickly the building daylight factor with Passivent’s ducted lighting systems- Sunscoops and Sunstracts™. It also enables calculation of the number and size of Sunscoops and Sunstracts required to achieve a given internal illuminance, and their associated impact on energy and carbon performance. Further, the Airscoop element of the tool has been upgraded for enhanced user interaction. For further information telephone 0161 905 5700 or email
