Legislating for zero carbon
Published: February 2010
Copenhagen was disappointing on a number of fronts. How useful or practical can a non-binding accord ever be? Politics usually gets caught between long-term goals and short-term vested interests, which makes securing consensus almost impossible on a global scale.

Ventilation energy requirements for six blocks of flats in Redbridge have been considerably reduced by controllable ventilation based on Vent-Axia Lo-Carbon Sentinel Twin fans. |
Controlled ventilation cuts energy use in Redbridge
Published: February 2010
Vent-Axia is working with Redbridge Homes to replace old central extract fans in six 11-storey blocks of flats with energy-efficient Lo-Carbon Sentinel Twin fans and time clocks. The level of control provided by the new fans will considerably reduce energy consumption. Ventilation contractor 1st Cool installed the 14 Sentinel units on the roofs of the buildings, connecting them to existing ductwork.

This 550 kW Remeha-Gilles biomass boiler has replaced oil in a Norfolk school and reduced CO2 emissions by 177 t a year. |
An education in biomass
Published: February 2010
Long-term reduction in carbon emissions are being achieved at a school in Norfolk following the replacement of 20+ year-old oil-fired boilers with a 550 kW Remeha-Gilles biomass boiler. The boiler house at Flegg High School in Martham was stripped out and refitted by Cofely. CO2 emissions are estimated to have been reduced by 177 t a year, and the financial saving is estimated at £7000 a year.
