2014 January

Faced with the high cost of running its oil-fired boilers and an £80 000 cost to install a gas main, Canons Brook Golf Club near Harlow has opted for a biomass installation. Ivor Marshall, chairman of the club, explains, ‘The costs to prepare and install a gas system made no financial sense, so we turned our attention to renewable sources.’

The BIM-wash-free style of last year’s event will continue. Speakers will cover all aspects of BIM — from the design of built assets through to their day-to-day management.

CIBSE has become aware of potential hazards in some biomass boilers when operating in slumber mode. The concern is that partial combustion might occur — generating unburned flue gases, including carbon monoxide. The institution is working to provide further guidance. In the meantime the following advice is offered.

Co-heating tests to measure the overall heat loss from buildings are inconsistent and highly sensitive to the weather, according to research by the NHBC Foundation. The study warns that doubts about the accuracy of the co-heating tests means that in its current form it is not a suitably accurate tool for reliably evaluating energy performance.

Heatrae Sadia

Heatrae Sadia has sharpened up its image with the creation of a new brand image and strap line. The logo has a crisp contemporary design, and the new strap line reflects the company’s commitment to delivering energy-efficient and intelligent hot-water products.

Adrian Walker, chairman of the ICOM Energy Association, which represents the industrial and commercial heating industry, has criticised ‘contradictory messages’ that seem to fly in the face of the need to address rising energy prices by using energy more efficiently. Opening the recent ICOM winter conference, Adrian Walker, who is managing director of boiler manufacturer Hoval, said, ‘There has been a frighteningly quick pace of change in energy prices over the last few years, accompanied by commercial pressures to get more from less — including heating energy.

Norwich-based architect Ingleton Wood has achieved reserved matters planning approval for what is believed to be the largest scheme in the UK designed to Passivhaus principles. It is for 250 riverfront apartments at Carrow Quay in Norwich, designed on behalf of local housing association Broadland Housing Group, which has recently completed its first rural Passivhaus scheme in north Norfolk.

CCHP, CHP, cooling

Trigeneration technology (CHP with cooling) can be a viable option for hotels, according to research at the University of Strathclyde. An MSc group project by students in the department of engineering in association with independent hotel operators Chardon Trading involved a feasibility study for CCHP (combined cooling, heating and power) at the Holiday Inn Glasgow Theatreland hotel (pictured). The approach was then applied to the UK hospitality sector through the development of a bespoke desktop tool for hoteliers to model their own scenario.

Preparations by Marshall-Tufflex to install a voltage-optimisation system for a manufacturer of heating products identified that electricity meters were making incorrect readings, leading to a refund of £65 000 and an assurance that future bills would be correct. The e-tracker sub-metering unit took only about half an hour to install between the main supply cable and the main distribution board, and its readings were checked a week later.

BCIA

Financial support for renewable heat for commercial and industrial projects has received a boost with the announcement of revised tariffs and support for more technologies. Commercial air-source heat pumps now qualify for RHI payments, and there has also been a substantial increase in the Renewable Heat Incentive budget for small and medium biomass, reducing the prospect of tariffs for such projects being gradually lowered. The changes come into effect in the spring of 2014.
