    Householders in Midlands in trial to remedy nation's draughty unblocked chimneys

    Across England there are 9 million fireplaces which are not permanently blocked. Often equivalent to keeping a window open at all times, an unblocked chimney can add significant cost to the typical heating bill as warm air escapes up through the chimney and into the atmosphere.

    Biffa saves 6,600 tonnes of CO2 emissions transporting material by rail

    Waste firm Biffa reveals it has saved 6,600 tonnes of CO2 emissions by switching to the usage of rail links for the transportation of mostly inert waste material to its facilities. This follows the Group's strategic rail partnership with GB Railfreight to increase its capacity for transportation via rail, thereby reducing its reliance on road haulage. Since last year, the Group has transported over 600,000 tonnes of inert waste by rail.

HWM data logger helps staff to quickly identify spikes in usage

An automatic meter-reading (AMR) system from utility telemetry specialist HWM has helped Okehampton College save £30,000 on its annual water bill.

HWM okehampton-college“A few years ago, our water bill was £50,000,” explained Keith Webber, technology coordinator at Okehampton College. “Last year, it was £20,000. The logger has made a huge difference to our awareness of how much water we’re using.”

The college’s datalogger is HWM’s MultiLog LX GPRS, which uses an external battery pack for advanced call frequency. The unit sends flow data every 15 minutes to HWM’s cloud-based server and then forwards that data to Pennon Water Services’ graphing system, BAO (Business Accounts Online). The data is also displayed via HWM Online, a customer portal for graphing and site management purposes.

Keith used the example of a single tap left running during a holiday period to illustrate the benefits of the AMR system. On that day, the college’s online interface showed a spike of £100 in water consumption, while electricity for an immersion heater also jumped by 3kW. As water and electricity use increased simultaneously, Keith could identify which one of 12 buildings the tap was located in.

“The hot tap had been on for 14 hours, but the electricity for the immersion heater cost something like three pounds. You think the electricity’s the expensive bit, but actually, it’s the water.”
