Glenigan Index

Commercial construction continues to show strong upward trend in activity

The value of starts for commercial construction projects in the latest report from Glenigan Index rose for the third consecutive month compared with the same periods a year earlier. The rises for November, October and September were, respectively, 4, 11 and 12%. Allan Wilén, economics director, commented, ‘These latest figures highlight the importance of rising public-sector confidence to deliver increased activity levels in 2015. Private housing and the commercial and industrial sectors are forecast to be the main engines for growth over the next 12 months.’

Why Building Information Modelling is not working ... yet

It is high time the industry got the Building Information Modelling (BIM) it actually needed and not the one foisted on it by software providers, according to B&ES president Andy Sneyd.

The global BEMS market — Henry Lawson.

Energy concerns drive growth in global market for BEMs

The global market for BEMS (building and energy-management systems) could almost double from its present level to over US$6.8 billion by 2020, according to Henry Lawson, a market-research consultant with BSRIA, in a new market report. The European market currently accounts for nearly half the market and is growing at 10% a year. The market in North America is growing faster than that figure, and the rest of the world even faster.

A coming together of BIM and commissioning

Commissioning is vital to the successful operation of buildings, and the growing deployment of Building Information Modelling opens up new possibilities and opportunities. Matt Ward of the Commissioning Specialists’ Association takes up the story.

Oil-replacement heat pump cuts energy bills for chartered surveyor

Chartered surveyor Powis Hughes has tackled the problem of rising oil costs to heat its premises, a converted 50-year-old barn in Berkshire, with the installation of a 20 kW ground-source heat pump. The Dimplex heat pump was installed by GHE and draws energy from eight trenches 50 m long, a metre deep and a metre wide in a large field next to the barn

Flakt Woods energy-efficient ventilation for university

A reversible hat pump and a thermal wheel are key features of Flakt Woods ventilation system installed as part of the refurbishment of the Arundel Building at Sheffield Hallam University. The system can supply up to 2.5 m3/s of conditioning air into a VAV (variable air volume) system and incorporates inverter-driven compressors. It replaces a natural-ventilation system.

The benefits of challenges of a larger ∆T in hydronic systems

So great are the benefits of a larger ∆T in hydronic heating and cooling systems that the issues posed to the commissioning process are well worth addressing. Chris Parsloe explains.

Remeha installs its first Fusion Hybrid system

Gas-fired absorption heat pumps now supply most of the space heating and support the DHW system at a care home in Banbury. Ken Sharpe was given the chance to look at the project.

SolarPV set to prosper without subsidy in UK

Solar power will prosper without subsidies in the UK as early as 2020, especially in the commercial rooftop market, according to a report* that uses the experience of Germany to project the outlook for solar costs in Britain and impacts on utilities. During 2015, solarPV will overtake both gas and coal to become the number-one power-generation technology in terms of annual installations.

Legislation update

Feedback from Hamworthy’s recent series of continuing professional development (CPD) presentations suggests that there is a lack of awareness in our industry about the pending Energy related Products (ErP) Directive. Mark Goodacre of Hamworthy Heating sheds light on what will be changing and the potential impact this will have for specifiers, consultants and contractors.
