As part of its commitment to greener working practices, Knauf Insulation has slashed gas consumption at the offices of its manufacturing facility in Cwmbran, Wales by more than two thirds, saving 74 tonnes of carbon in one year.
The annual energy consumption in the office buildings has plummeted from 574,560kWh to 186,960kWh, reducing the offices’ heating bills by 67 per cent.
Data shows that carbon emissions from the offices have similarly dropped, falling from 109 to 35 tonnes per year – savings that far outstrip the original estimate of 40 per cent.
The savings are particularly significant given that the mean temperature over the UK in winter 2012/13 was 0.4°C below the 1971-2000 average, according to figures supplied by the Met Office. Furthermore, March 2013 was the coldest March since 1962, with a mean temperature 3.3°C below the average.
The savings have been achieved thanks to the introduction of two Remeha Quinta Eco Plus 115 passive flue gas heat recovery heating systems, as well as improved heating controls such as thermostats, timers and zone valves.
The move is part of a wider commitment to improving sustainability by Knauf Insulation, which has also seen the manufacturer achieve zero waste to landfill at Cwmbran, as well as its three other UK production sites.
Knauf Insulation has introduced a number of measures to divert both production and office-generated waste, for example baled glass wool waste is re-used by a ceiling tile manufacturer, while mixed glass wool and incidental packaging waste is collected by a recycling partner and re-processed for use as underground bedding.
Oleksandr Prykhodko, plant manager at Knauf Insulation’s Cwmbran facility, commented: “Minimising our environmental impact is a central focus of our sustainability strategy, so reducing the energy we use and the waste that is generated at our production plants is a key aspect of this. We are really pleased with the progress we have made at Cwmbran and look forward to improving this even further over the next 12 months.”
