THE MEDIA BRAND FOR THE BUILDING SERVICES INDUSTRY
11 DECEMBER 2013
Autumn statement broadly welcomed Dennis Flower firstname.lastname@example.org
The government’s autumn statement has received a largely positive welcome from the building services sector. In his speech last Thursday, chancellor George Osborne raised predictions for UK economic growth next year from 1.8 per cent to 2.4 per cent. One area of contention has been changes to the Energy Companies Obligation scheme. A number of building services suppliers had enjoyed increased workloads from the initiative, which has now be extended for two years but with no extra investment. This has sparked warnings that the scheme is being watered down and its effectiveness in fighting fuel poverty reduced. UK Green Building Council chief executive Paul King said: “Tax cuts for shale gas are a stark comparison to the butchering of ECO we’ve seen this week.” The Green Deal updates proved less contentious, although the industry would like to see more improvements in the future, and the reaction to the
commercial and domestic RHI statements were largely positive. The news that the government would retain the carbon floor price of £4.94 per tonne of CO2 was welcomed by WSP head of environmental business Mark Hurley, who was pleased no changes had been made. “But it should probably have been made clear that this will add £5 to energy bills next year,” he said. “The extra £400m raised by the scheme next year should be used to make one million Green Deal loans of £3,000 at ‘zero interest’, and really transform the programme.” The Local Infrastructure Fund, launched in last year’s autumn statement to unlock stalled housing projects, has
received a £1bn extension, the chancellor revealed. Originally launched with a £225m allocation, this received a boost of £102m in last June’s spending review. B&ES chief executive Roderick Pettigrew said the focus on ‘green subsidies’ was a relatively minor issue compared with the need for investment in construction and infrastructure. “The £375bn announced for infrastructure spending could have a huge, galvanising effect, but many of the projects remain far in the future,” he said. “The chancellor has a vision of a more productive future and he is doing many of the right things to make it happen,” Mr Pettigrew said. However, other issues still needed to be addressed, he added, including reforming payment practices, with only firms that pay on time allowed to bid for public sector work and increased use of project bank accounts to protect suppliers. moRE Govt AnnounCEmEnts Full reaction to all the latest measures

BETTER TIMES MAY BE HERE TO STAY Following the slew of announcements that followed prime minister David Cameron’s stated intention to address ‘green levies’, it was a relief to finally see the government’s autumn statement last week. Scrapping the planned fuel duty rise, the capping of business rates and more export finance support will all help various elements of the building services sector, in addition to the measures outlined on this issue’s front page and those on pages 3 and 4, which will all help our sector in one way or another. What we need to see, of course, are higher levels of work and signs of these are emerging. Our recent survey on profitability saw a broad spectrum of comments on current conditions within the industry, from dire

A look at pumps
The industry awaits next year’s domestic Renewable Heat Incentive and its effect on solar thermal installation numbers. Industry experts also give their views on a number of issues relating to water heating, including those affecting heating systems in general.
With air-to-water heat pumps now included within the commercial Renewable Heat Incentive and tariffs announced for the domestic version of the scheme, heat pumps are receiving increased levels of attention from the industry as 2013 draws to a close.

Updates to commercial and domestic RHI welcomed dennis Flower firstname.lastname@example.org
The Department of Energy and Climate Change has made announcements for both the commercial and domestic versions of the Renewable Heat Incentive that have been broadly welcomed by the industry. Additions were made to the commercial RHI to include air-towater heat pumps, biogas combustion (subject to state aid approval), biomass combined heat and power and deep geothermal heat. Air-to-water heat pumps will have a tariff of 2.5p/kWh and 4.1p/ kWh for biomass CHP, with solar thermal increased to 10p/kWh. Tariffs were also confirmed for the domestic RHI, including 7.3p/ kWh for air-source heat pumps,
General RHI degression level
18.8p/kWh for ground-source pumps, 12.2p/kWh for biomass and 19.2p/kWh for solar thermal. Details of degression levels were also released for the domestic RHI to control the budget. These will include a general level of 10 per cent, plus a ‘super trigger’ of 20 per cent to avoid over-deployment of any of the technologies under the scheme. Micropower Council chief executive Dave Sowden told H&V News that the association welcomed the RHI announcements.
“We calculate that the airsource heat pump tariff will hit its degression figure fairly early on, because the market is already close to 17,000 installations, but the scheme is still viable.” His comments were backed by industry insiders, who said that air-source heat pumps would provide the highest levels of return within the scheme. Mr Sowden described the degression levels as “sensible”, while stating other details needed to be “picked through”, such as the under-deployment of groundsource heat pumps. Adjustments to bio-propane, large biomass, ground-source heat pumps and landfill gas within the commercial version of the scheme resulted from calls for evidence issued earlier this year.

Changes to the Green Deal announced by the Department of Energy and Climate Change last week are “playing around the edges” and fail to solve the growing concerns around energy bills, according to industry figures. The changes are designed to improve Green Deal engagement for both consumers and Green Deal providers, the DECC said. Measures include the launch of an online advice portal, improving assessment advice report and allowing access to Energy Performance Certificate data. The government also plans to work with industry to cut the cost of insuring Green Deal measures. Further changes will result
Reducing energy bills by £50 a year is largely meaningless to most people” from discussion with the Green Deal Finance Company, the DECC said, including same-day processing of Green Deal Plans, updating legislation for the benefit of landlords and tenants and making ‘top-up loans’ more attractive. The government has also extended the Energy Companies Obligation by two years. Both ECO and Green Deal announcements have been met
with criticism by industry experts. Green Heat managing director Peter Thom said the moves show “the energy question has unfortunately become a political football”. “The government is limited to what it can do and the recent statements of reducing energy bills by £50 a year are largely meaningless to most people,” he continued. Compared with other countries, the UK continues to have cheap energy and an inefficient housing stock, Mr Thom said. He suggested raising VAT on energy bills to 20 per cent to raise revenue to tackle fuel poverty issues without burdening industry.

Fuel poverty redefinition branded ‘unacceptable’ Dennis Flower firstname.lastname@example.org
Changes within the Energy Bill to redefine fuel poverty classification were branded “unacceptable” by the Environmental Audit Committee last week. It was reported that the changes would reduce the numbers of people listed as being in fuel poverty from 3.2m to 2.4m. The cross-party members of the EAC said ministers were “shifting the goalposts” to reduce the numbers, branding it “unacceptable”, the BBC reported. People who spend more than 10 per cent of their income on heating bills are currently defined as being in fuel poverty. The changes would see fuel poverty redefined as affecting
Number of people that would be defined as in fuel poverty under the proposals those with higher-than-average fuel costs that drag their income below the official poverty line. The reason for the change was to gain an improved understanding of the issues surrounding fuel poverty, the government said. EAC committee chair Joan Walley told the BBC the changes were being implemented “so that official statistics record far fewer
households as fuel poor”. “The changes to the fuel poverty definition and target, in part being made through amendments to the Energy Bill, should be stopped unless the government is prepared to make a public commitment to end fuel poverty altogether,” she said. Ms Walley added that shortterm measures to reduce energy bills should not adversely impact climate change policies. The political debate over energy bills has intensified over the last two months, with David Cameron coming under fire for comments made on “green levies”. Ms Walley said: “In the longer term, green levies could actually keep bills down if they drive energy-efficiency improvements that cut the cost of heating homes.” hvnplus.co.uk

Regent’s Place gears up for Excellent BREEAM rating Dina Patel email@example.com
London’s Regent’s Place, more than 10 years in development and aiming for BREEAM Excellent for its North East Quarter, has started to host visits to the site ahead of its opening next summer. The site features a number of initiatives including 22,000 sq ft of green roof, the design of which was a two-year pilot with Arup. The rare Black Redstart species of bird has been spotted on the roof, highlighting the biodiversity attracted to the Sir Terry Farrell masterplanned site. The estate’s award-winning sustainability features include a PV installation, producing more than 15,000 kW/h each year. Water management systems will harvest around 2.4m litres of rainwater annually, which will then be recycled for toilet flushing, as well as irrigation purposes. In 2010/11, zero waste went to landfill, with 402 tonnes being recycled and the remaining 667

tonnes incinerated and converted to power – the equivalent of a £56,600 saving in landfill taxes since 2008/09. The estate as a whole is designed to be up to 32 per cent more carbon-efficient than current standards. Contributing factors include enhanced building airtightness, high-performance glazing, motion and daylight sensors, electronic energy monitoring and high-efficiency centralised HVAC systems. The TECS HVAC systems installed provide a compromise between low noise attenuation and efficiency. Central AC energy consumption at 10 and 20 Triton Street and the NEQ development has been reduced by 40 per cent compared with other solutions, it is claimed. Buildings on the site have been designed to exceed carbon emissions regulations by 50 per cent. ALL THE LATEST CONTRACTS at our dedicated online section hvnplus.co.uk/news/contracts

The industry’s trusted source of data, analysis and project leads www.glenigan.com
Sectors, data, contract leads RETAIL The retail sector has experienced an upturn following year-onyear contraction every quarter since the middle of last year. Intelligence provider Glenigan recorded a 2 per cent increase in the value of underlying starts (valued at £250k-£100m) during the third quarter of 2013. This slight improvement follows a disappointing start to 2013, with the value of contracts awarded in the first half of this year below the level seen during the first half of 2012. The regional numbers for the third quarter were hugely varied across the country. The NorthWest, the South-east and the West Midlands all posted significant year-on-year declines. Wales in particular recorded a sharp drop in retail activity of 73 per cent compared with the same period of 2012; the region’s quarter-on-quarter contraction was even sharper, with Wales going from £21m of starts in Q2 to £3m in Q3. London fared better than other urban areas, going from £37m of starts in Q2 to £97m in Q3. The East Midlands, Yorkshire and the Humber also recorded excellent results for Q3. Among these stronger regions, notable projects to have started on site over Q3 included a £20m scheme for six retail units in Humberside for Simons Construction, which is being delivered by Simons Construction; a £10m supermarket and petrol filling station in Nottinghamshire for Wm Morrison Supermarkets, for which Bowmer & Kirkland is the main contractor; and a new £5m indoor market in Leicestershire for Leicester City Council, which was awarded to Kier Construction. The near-term forecast for retail activity has improved in recent months, driven mainly by the increase in consumer 12 11 DECEMBER 2013

confidence and signs that the wider economy is beginning to recover. Glenigan anticipates an increase in refurbishment and fit-out work to account for the expected growth in retail construction activity. In response to the improved market, retailers are integrating their online presence and offering more choice to consumers – ‘click and collect’ systems being one for example. Glenigan says this will require change to existing retail premises, which will need to accommodate the collection services. The outlook for retail is for growth to continue into the final quarter of the year and into the majority of 2014.

BANK OF ENGLAND MORTGAGE APPROVALS The most recent data from the Bank of England reveals that the total number of mortgage approvals for house purchases rose dramatically over the three months to September 2013. Approvals hit 66,735 in September, an increase of 5.3 per cent compared with the previous month and up 33.9 per cent against September 2012. The three months from June marked the first steady and sustained growth since the last four months of 2012. Help to Buy is unsurprisingly credited with much of this improvement in approvals and the wider housing market, combined with increased confidence in the economy among lenders and homebuyers.

NSCC SUPPLIER PRICES The National Specialist Contractors Council State of Trade Survey measures the performance of specialist contractors in the construction industry quarter on quarter. These figures represent the net balance of those firms who said they saw an increase in suppliers’ prices during the quarter minus those who reported a fall. The latest numbers from Q3 2013 show that, for the first time since Q2 2008, no respondents recorded a decrease in suppliers’ prices, down from 4 per cent in Q2. The percentage reporting an increase in suppliers’ prices was at a three-year low of 57 per cent, down from 58 per cent, with the remaining 43 per cent seeing no change in prices during the quarter. hvnplus.co.uk
These figures show the total value of mortgage loans for house purchases over the year to September 2013, according to the Bank of England. While changes in the value of loans typically mirror changes in the level of approvals, their increase has been markedly steadier since May this year. This increase has nevertheless been dramatic, with the value of loans passing the £10bn mark in September to hit £10.08bn – representing a whopping rise of 5.1 per cent compared with August’s £9.59bn and an even more impressive 36.9 per cent increase on the same point of the previous year. The newly launched second phase of Help to Buy is likely to spur these rises still further.

Special report Water heating
Timely opportunity for fresh heating solutions While tried and tested methods have their place, there are plenty of other options out there for improving efficiency and reducing costs With the Building Regulations dictating increasing thermal efficiency for new-build projects in recent years, combined with compliance with standards such as BREEAM and increasing acceptance of Passivhaus principles, the resulting reduced demand for heating is increasingly turning attention to the effective delivery of hot water. Due to next year’s domestic Renewable Heat Incentive providing additional support to solar thermal installations, in addition to that already provided by the ongoing grants within the Renewable Heat Premium Payment scheme, increasing uptake of this technology is forecast. Research conducted by the Solar Trade Association shows that the cost of installing solar thermal systems will be considerably reduced if they become more common. However, the survey predicts that this will not emulate the situation within the solar photovoltaic sector, which has seen substantial reductions in the cost of equipment and components due to higher sales volumes and a resulting increase in price competition between suppliers. Where solar thermal is concerned, market expansion by a factor of 10 would result in price reductions of nearly 30 per cent, driven by efficiencies on installation. Equipment price reduction will play a part in this, but not to hvnplus.co.uk
the same degree as with PV, the survey predicts. STA chief executive Paul Barwell says: “The message here is not that customers should wait for cheaper systems, but that from a macro-economic perspective, solar thermal is ready to realise its mass-market potential and make a major, cost-effective contribution to the UK’s renewable energy objectives.” The STA study shows that PV equipment costs have fallen by 66 per cent since 2011, while installers’ non-equipment costs have been reduced by 49 per cent. The paper forecasts a reduction of 21.6 per cent in equipment costs and a 35.8 per cent in non-equipment costs for solar thermal – a 29.2 per cent cost reduction overall – if it is able to enjoy a similar level of market growth as PV. Minimum standards
The Building Regulations also include minimum standards for systems, including those with stored domestic hot water, according to Honeywell marketing and communications manager Andy Mansfield. When major changes are made, such as the installation of a new cylinder, the regulations require existing systems to be upgraded accordingly. The use of wireless technology is proposed as a simple and effective method of upgrading a

system. The cost of these is often quickly recovered through fuel savings, Mr Mansfield claims. “Stockists hold different types of advanced time proportional and integral control packs that include a wireless enabled programmer and wireless room thermostat,” he says. “The pack for a system with stored domestic hot water also includes a wireless cylinder thermostat. “Room and cylinder thermostats should be easy to install, with, in most cases, the new programmer replacing the original timer on the backplate.” Durapipe building services brand manager Des Dolan 11 December 2013 17
Special report Water heating (continued) cites the energy-efficiency of plastic piping as one consideration, adding that there are further advantages to be had. When compared with metal alternatives, plastic piping is more environmentally friendly, requiring less energy to create and is far easier to recycle, he says. Its lightweight nature also means that it is easier to transport, providing additional transport and installation advantages. Once it has been installed, it will continue to deliver energy savings over the lifetime of the system, Mr Dolan continues. “All plastic materials have low thermal conductivity, resulting in less heat loss through the pipe wall, which minimises the need for insulation,” he says. “The smooth bore of plastic pipework systems means flow will not become restricted, ensuring the same flow rate during the system’s lifetime, guaranteeing that the energy required to pump substances through the system does not increase as the pipework ages.” Effective pumping
Pumps form an equally crucial part of the heating system mix and new research conducted by Spirotech raises some important points to take into account. National sales manager Martin Wilkinson says his company’s analysis reveals that effective dirt separation measures are imperative to derive optimal benefits from new generation, high-efficiency circulation pumps with ECM technology and permanent magnetic motors, he says. “The study has identified how circulation pumps, introduced in line with the Eco Design Directive 2009/125/EC, are sensitive to magnetite present in system water, but will retain their theoretical efficiency as long as water cleanliness standards are protected by the installation of a high-performance dirt separator with magnetic qualities,” he says. 18 11 DECEMBER 2013
Eco pumps will retain their efficiency as long as water cleanliness standards are protected” Martin Wilkinson, Spirotech
Energy-saving pumps are particularly sensitive to magnetite in system water, as their rotors are permanently magnetic and magnetite adheres to the rotors, whereas older pumps are only magnetic when the pump is running. The research demonstrates the effect of magnetite build-up on pump efficiency by comparing conventional, asynchronous pumps with similar new generation eco pumps. “In the case of the modern pumps, magnetite had a clear and substantial negative effect on efficiency,” Mr Wilkinson says. “The situation can be directly compared with what happens in practice in an ordinary system.” In the laboratory tests, the new generation pump efficiency was reduced by between 10 to 15 per cent, with the study also indicating that over time, the pump’s efficiency could even be halved if the water is left untreated. The simple solution to the problem is to install a highperformance magnetic dirt separator to safeguard against magnetite build-up in system water and create optimal conditions for the eco pump to realise its true potential, Mr Wilkinson says. Timely opportunity
The results of another research initiative, commissioned by Adey Professional Heating Solutions, are cited by its sales director Paul Strudley to emphasise how installers can increase their work
levels and deliver effective benefits to customers. Mr Strudley points to the response from 1,300 homeowners, which reveals that one in 20 consider an annual boiler service an unnecessary expense and almost a quarter of people living in their home for at least 15 years admit to never having had their boiler serviced. “Our research suggests many people don’t understand the benefits that having an annual boiler service will bring, and worryingly, just let their good old boiler in the corner keep chugging away without giving it any attention. “ The current climate presents a timely opportunity for customers to learn how a well-maintained and efficient boiler can save money on heating bills, reduce the risk of breakdown and, crucially, ensure it is safe to use. “Installers can be assured that many of their customers will welcome this advice, as threequarters of homeowners surveyed wanted to know about the simple changes they can make to their central heating to reduce energy bills,” Mr Strudley says. Corrosion deposits in central heating systems cause a reduction in performance, noisy pipework, radiator cold spots, low heat levels, slow operation, leaking valves and ultimately the breakdown of the system. “With a better protected system, the average household could achieve maintenance savings of more than 30 per cent a year, reduce energy bills by up to 6 per cent year on year and extend the operational life of their boiler way beyond the industry accepted lifespan of 12 to 15 years. “What customer wouldn’t be interested in knowing how they could achieve that?” Mr Strudley says.

Special report Heat pumps
Warming up to an established technology The future is looking brighter for heat pump installations, although more education is required for some end-users and installers Following the widespread use and acceptance of heat pumps in other European countries, many industry observers expected that this success would be repeated in the UK. However, these expectations have remained largely unfulfilled for several reasons. The global economic downturn has been a factor, with businesses and homeowners feeling the squeeze and reducing expenditure. Heat pumps continue to cost considerably more than traditional options on average, so convincing end-users to invest in a technology they are unfamiliar with has proved challenging. Unfamiliarity has also led to heat pumps being regarded as new technology by building owners, although they have been around for several decades. A further issue the market has had to deal with is the negative publicity, including reports of poorly designed systems in the national media highlighting the high energy costs experienced by end-users. The initial study by the Energy Saving Trust in 2010 on heat pumps was also seen as largely negative, typically through the issues of poor design and installation. However, The Heat is On, a study published by the trust in August this year, showed a far more positive picture, reflecting the opinion of many in the industry who predict that heat pumps will enjoy a growing market share. hvnplus.co.uk
Among its various findings, the EST said heat pumps can perform to a “very high standard in UK homes”, supported by the results from technical data and feedback from users. Better installation standards, following the revised Microgeneration Certification Scheme’s standards, had played a major part in this. The MIS3005 heat pump installer standard was updated in 2012, having been designed to provide consistency within UK installations of heat pumps. The revised version stated that systems should be designed to meet the entire heating requirements of the building, reducing the need for supplementary methods to be used. The extra mile
While The Heat is On report indicated further advantages could be gained through higher levels of understanding of operating options and controls by end users, it also considered systems running continuously and intermittently. The EST said there is “a number” of the latter in existence, which are delivering high levels of customer satisfaction. There are a growing number of voices suggesting that heat pumps will experience higher sales numbers as the economic recovery continues next year. The recent upsurge in housebuilding is seen by many as a key element within this.
The difficulty lies in raising awareness of the technology” Jonathan Tedstone, Baxi
Among those predicting better times for heat pumps in the future is Worcester, Bosch director of marketing and technical support Martyn Bridges. He believes this will in part be driven by Building Regulations and the move towards zero-carbon homes. “The new-build sector in particular will have little choice but to look at air-source or groundsource heat pumps as a primary heating and hot water technology,” he says. “It therefore seems likely that we’ll see big sales of heat pumps from around 2016 onwards, driven by regional and national housebuilders needing to comply with the regulations.” 11 December 2013 21
Special report Heat pumps (continued) A staged process towards renewables is a sensible approach, Mr Bridges continues, and the industry should be encouraging homeowners to invest in boilers – which are typically distress purchases – assisted by air-to-water heat pumps in the future. Extensive insulation is also advised by Mr Bridges within a three-phase process that may take some time to complete, but at least provides an effective roadmap to bringing heat pumps to the forefront of domestic heating in the future. Next year’s launch of the domestic Renewable Heat Incentive is also seen as a positive move for heat pumps. Statement of support
Baxi product manager Jonathan Tedstone says this move by the government is a clear statement in support of renewables, and heat pumps in particular, as a workable option for many homeowners over the coming years. “The difficulty, however, lies in raising awareness of the technology,” he says. In a recent government report entitled Homeowners’ willingness to take up more efficient heating systems, very few consumers would actually consider the installation of low-carbon technology in their homes, and awareness of renewable technologies remained very low. Yet with government incentives driving installation of products such as heat pumps and the new-build sector obliged to meet the zero-carbon standards by 2016, it is hoped consumer awareness will begin to rise for all renewable technologies. “Another key aspect that must also be considered, in any new heating installation, is the overarching efficiency of the system,” Mr Tedstone says. “There is no point, for example, in installing a highly efficient heat pump solution in a draughty inefficient home; the potential gains are lost almost instantaneously.” 22 11 DECEMBER 2013
In new-build developments or whole-house refurbishments within off-mains-gas areas, heat pumps can provide energyefficient and viable alternative heating, but only if installed in the correct application. “The key message to installers is that there are real savings to be made from renewables, but there is not a one-size-fits-all solution and homes must therefore be considered on a case-by-case basis,” Mr Tedstone explains. Here and now
While there is increasing optimism for future uptake of heat pumps, Dimplex Renewables product marketing manager Clare Campbell says the current market already offers plenty of opportunities for their use. She highlights the case of larger homes located off the gas grid, where the latest 12 kW and 16 kW air-source models will prove particularly effective. Mr Campbell also points out that the domestic RHI will recognise qualifying installations completed before the launch next spring, offering a further boost to existing opportunities. “Customers are looking at renewable technologies to save money on their heating bills,” Ms Campbell says. “The Renewable Heat Premium Payment Phase 1 Customer Survey, published by the DECC in 2011, revealed that 82 per cent of consumers with renewable heat technology said rising fuel prices were the motivator for their investment. “However, to access the RHI, installers will have to be Microgeneration Certification Scheme-approved. “It is also vitally important to not only attend generic technology training offered by commercial training providers, but also to be trained by your equipment manufacturer of choice – who, after all, are the experts in the technologies and can relay the
Customers are looking at renewable technologies to save money on their heating bills” Clare Campbell, Dimplex
specific requirements for their individual properties. “Nowhere is this more important that in the area of controls. Manufacturers can also support this with correct sizing and system design.” Case in point
Heat pumps’ growing importance has also been evident in the increasing number of heat pump installation case studies featuring in H&V News. This type of information is typically only released when the end-user has given their permission, which usually indicates that a high level of satisfaction has been achieved. Concern has been expressed, however, over the numbers of MCS-registered installers. This figure declined on the back of the Feed-in Tariff cuts last year and has shown little movement in the intervening period. Next year’s launch of the domestic RHI is therefore expected to impact this number, with more installers becoming involved in order to take advantage of the scheme’s introduction. Heat pumps continue to generate considerable debate, including both negative and positive opinion, yet the evidence shows the technology can be effective when correctly designed, installed and operated.

major concerns require collaborative solutions Leading industry figures met to discuss what the industry must do to tackle pressing issues such as retentions, PQQs and skills shortages
With a number of national and industry surveys predicting improving conditions within the construction sector, there are numerous issues to address that will impact the speed with which contracting companies in the industry can benefit from increased opportunities. H&V News assembled 11 industry professionals to debate the current status and thoughts on future developments. Our latest roundtable discussed the different views on how the industry should prepare to move forward within hvnplus.co.uk
the context of the new government strategy for construction. Retentions slammed
NSCC chief executive Suzannah Nichol began the discussion by addressing the issue of retentions. “You have to look at the whole payment and supply chain and the issue of trust when looking into retentions,” she said. “We should be questioning why we have payment issues in our industry. “Looking just at retention will never solve the issue; we need to address it on a wider scale
We’ve been in a buyers’ market for the past five years and we’re all beginning to feel pressure on our labour” Steve Hale, Crofton
and make it redundant.” Others asked why the industry has retention at all. Calling it an archaic practice, some argued the unfairness of withholding money from someone who has delivered their contract. Ms Nichol said: “We all know the reason is to hold on to cash. I don’t think those people withholding realise how damaging it is and tier one contractors recently said the biggest risk to their business is their tier two contractors going bust. “Withholding retention is 11 december 2013 27
Attendees a sure way of damaging the tier two contractors. It’s incredibly damaging to our industry as a whole.” Skanska business director Russell Hallmark added: “There are some principal contractors who have a slightly different way of dealing with retention. “There are some developers that charge no retention and we work with developers who have taken it off the table. Providing there are no defections at the end, there will be no retentions. “This still isn’t ideal but it seems more reasonable. We all trade on the back of cash, cash is profit and if cash isn’t there then you won’t be able to do business. We’re restricting advancement and there is the cost of sitting down every time and negotiating.” Interserve strategic development director Ross Mather argued: “I’d like nothing more than to eliminate retention, but by nature business is financially driven and retentions have coexisted for hundreds of years, and yes perhaps a minor number within industry do cheat the system to protect themselves against insolvency by keeping the cash in their own pockets, but wholesale change will be difficult unless supported with a competent, 28 11 december 2013
good-quality supply chain.” Others agreed that clients should be better informed with regards to their contracts, especially with many clients overlooking the small print that shows retention to be 5 per cent. Call to action
Crofton managing director Steve Hale added that now was the time for change. “Now would be the right time, as we’ve been in a buyers’ market for the past five years and we’re all beginning to feel pressure on our labour,” he said. “It will soon become a seller’s market.” Others agreed that there will be a natural transition towards a seller’s market. Ms Nichols argued that the industry needed to become smarter and that there was a strong need for better organisation and good management out on site. “It’s a travesty that clients are saying they no longer trust the industry and as such are going to self-deliver,” she said. The debate identified a real space for good management, good operation and delivering what the clients want. Some agreed that clients are not entirely blameless. It was argued that clients come up with

a number of obscure reasons to prolong payment if their tenants are not ready to take over the building. It was suggested by one attendee that the industry should start with gradual change – for example, by protecting retentions rather than taking them off the table completely. The government was mentioned as one of the biggest culprits when it comes to retentions. Aecom building services engineer Ant Wilson said: “My biggest struggle with getting money is from the government. They keep changing their departments – the money is split between different departments. We’ve lost so much when venturing into European government work and we’ve chased between 18 months to two years to get money out. Also, there is still 10 per cent retention.” United front
It was agreed by the majority that the industry should be standing collectively and saying no to retention from the top to ensure better business practices. USUS Group building services consultant and energy specialist Mike Mann added that retention was once an incentive to complete a job but it had been twisted into a mechanism to manage cashflow and to keep projects financed. It was agreed around the table that if a firm had done the job, they should get their retention. Ms Nichols said the NSCC has had plenty of success with smaller companies who have been successful in asking for retentions to be excluded from their contract. Ms Nichols added that more and more contractors were seeing retentions as an unfair practice. However, Kershaw Group sales director Ian Greenstock said there will always be one contractor who takes the deal with retention. “Some companies take the order to keep people employed, as it is easier to take a job at a low price rather than make their employees redundant,” he said. hvnplus.co.uk

Roundtable (continued) It was agreed, however, that retentions should stay out of government contracts for most specialist contractors. Better communication was also suggested to avoid repetitive form-filling. It was suggested that the industry was disappearing into its own paper trail. Mr Hallmark argued that it was down to the government to lead by example and motivate the industry from the bottom up. Ms Nichols countered by saying it was up to the industry to step up rather than asking the government to intervene. PQQ issues
Industry contractors often raise concerns over the burden of prequalification questionnaires and Mr Mann argued that although it was a consultant’s job to be fair to people, PQQs had taken on a solicitor’s role. Others argued that the biggest problem was the large amount of people bidding for every single job. Ms Nichols said main contractors needed to say how they prequalify their supply chain and that the industry needed to develop one simple system. “We drown in unnecessary paperwork because we allow others to dictate how we work,” she said. “We are employing form-fillers and form-checkers when we should be spending time on innovation.” It was suggested that people in the industry sit down with the major trade bodies and come up
with one standard rather than have the government tell the industry what to do. Ms Nichols said the industrial strategy had identified the issue of form-filling as a problem, saying it was inefficient and costly. Mr Hallmark pointed to the Achilles framework, which allows firms to pay only one fee to avoid going through different processes. According to Mr Hallmark, the framework worked well until the downturn hit and people decided to pull out when they could no longer afford it. It was argued that there should be just one fee and one form and that this would drive down costs by creating just one type of accreditation. This would force everyone to buy into one scheme and pay the fee. It was suggested that the industry explain to business secretary Vince Cable how it needs to be done.
It’s hard to get the right people. This is a problem caused by years of not having a uniform way to get people trained”
way but business pressures have caused this area to slow down.” It was suggested that the industry has not invested in the younger generation since the mid-1990s and that it was only just turning the tap back on in terms of spending. Attendees stressed the need for the government to allocate spending in this area. It was also accepted that the industry needed to make itself appear more attractive to the younger generation and to offer a more strategic way into the business.
Matthew Edwards, Swale Heating
The industry has increasingly voiced its fears over the loss of its workforce and the need for a recruitment drive, with motivating more apprentices a particularly pressing concern. Mr Edwards commented: “Over the last few years the intake has reduced significantly, but we are trying to drive apprenticeships. It’s hard to get the right people. This is a problem caused by years of not having a uniform way to get people trained. “We’ve done it in our own

BIM was suggested as an attractive job role for graduates who are up to date with computer and visual skills. However, a huge skills gap was identified with regards to BIM, with one attendee arguing that most graduate engineers spend more time in front of computers than they do out on site. Another problem area identified was the lack of training for site apprentices. Many places no longer host the required courses and students in the South-east are now stuck with only two options for colleges: South Bank and Southampton. It was argued that the huge drive for young adults to enter university had led to a fall in the number of people entering the construction sector. It was agreed that more time needed to be dedicated to schools. “Also, restrictions on site are causing more apprentices to start when they are 18 years old,” Ms Nichols said. Some argued this had led many 16-year-olds who did not want to carry on with further education to be ignored. The roundtable agreed, however, that graduate-level managerial and professional posts were expected to increase significantly in the next decade, as construction remained a crucial part of the UK economy. hvnplus.co.uk

Special report Case study
Leisurely retrofit reduces council running costs A leisure centre has slashed its energy bills after spotting an opportunity to replace its ageing boilers with condensing models Totton Health and Leisure Centre in Southampton, Hampshire, prides itself on providing the best leisure activities in the local area. As part of an initiative to enhance the facilities available to visitors, the centre underwent a substantial refurbishment in 2012, which included retrofitting the reception area, extending and refurbishing the gym, re-tiling the main and learner pools and installing a brand new changing village with additional showers. When the works were complete, feedback from visitors revealed they were very happy with the new facilities and Totton’s membership grew. The next step was to increase energy-efficiency and reduce carbon emissions and running costs, so the council looked into replacing the existing standard efficiency boilers with condensing appliances. There was also another issue that needed addressing to meet growing demand for the leisure centre facilities: due to an increase in the number of showers, visitors began to complain of extremely low water pressure, especially when all showers were in use. New Forest District Council commercial gas engineer Rob Sowden used a data logger to record water pressure over a fourweek period. He discovered that pressures dropped to as low as 0.5 bar at peak times, causing showers to trickle and even stop. 32 11 December 2013
The answer was to install a new booster set that would ensure constant water pressure for the showers at all times. This needed to be installed in the plant room, along with a new water storage tank which, due to its size and dimensions, required the boilers to be repositioned. Mr Sowden realised this was the perfect opportunity to replace the boilers. Out with the old
In addition to replacing the old boilers with more modern versions, the new flueing arrangements for these needed careful thought. “The Clean Air Act states that no more than 150 kW can

be terminated through an external wall with a power flue,” Mr Sowden explains. “As the total output of the new boilers is 400 kW, we had to examine alternative options. The first option was to install five individual vertical flue kits up through the roof of the boiler room; the second was to employ a specialist flue company and have them install one large flue through the roof, connecting all five boilers to the main header. “As terminating through a roof can lead to weathering issues, we decided to go for option two so that there would be only one termination point to maintain.” hvnplus.co.uk
Mr Sowden brought in a flue specialist company, which proposed installing a 316 stainless steel liner, 300 mm-grade 304 stainless steel outer casing and 25 mm void packed with dense mineral wool fibre, with 100 mm short plastic branch legs from the boilers to the main stainless steel header. The height of the flue was 1.2 m above the roof line and Mr Sowden ensured that approval was obtained for the flue installation from Building Control at New Forest District Council prior to work commencing, so any potential issues could be addressed at an early stage. Open for business
An additional challenge was that the leisure centre had to remain open during the installation, so the hot water system had to be working during opening times and the swimming pool’s water temperature needed to be maintained. Rather than using the services of a consultant, Mr Sowden tapped his expertise as a highly skilled engineer to design, install and commission the new system. This was completed following an on-site consultation with Ideal Commercial Boilers business development manager Mike Stubbs, and attendance at a training course at the company’s Centre of Excellence in Reading to further expand his knowledge of the products he had chosen. Consultants were then hired to approve Mr Sowden’s design, rather than create the design from scratch, saving the council an estimated £7,200 in fees. Mr Sowden decided the Evomax condensing wall-hung appliances from Ideal Commercial Boilers were the most suitable. He had recommended these to the council, not only because he had installed them before and had found them to be reliable and easy to maintain, but also because of their space and energy-saving capabilities, which would additionally help to meet hvnplus.co.uk
the requirements of the centre. The installation was planned for the summer so that the demand for space heating would be low, and at a time when the leisure centre would be quiet. Mr Sowden installed the five new boilers adjacent to the old floor-standing models, which meant 80 per cent of the installation work could be completed without disconnecting the existing system. When no further preparation work could be done, the old boilers were disconnected and the pipe connections transferred to the new ones as quickly as possible. Mr Sowden had allowed two days for the boilers to be connected, though the switchover was completed in less than eight hours, resulting in a seamless transition, with no loss of temperature for the building or swimming pool. The old boilers, which had been in service for 26 years, were removed so that the booster set and water tank could be installed. Fall in complaints
Since the new plant equipment has been installed, Totton Health and Leisure Centre manager Ross Archibald says no visitors have complained about the showers. Mr Sowden confirmed the technical reason for this with the data logger, which showed that the showers were consistently

operating at a healthy pressure of 3 bar – even when all the showers are in use at the same time. In meeting the council’s requirement to minimise energy use in the building, the new condensing boilers are reported by their manufacturer to offer efficiencies of around 98 per cent. Mr Sowden predicts the resulting reduction in running costs will save the leisure centre around £6,000 a year, or 15 per cent, dramatically reducing the payback period for these appliances, as well as delivering future energy savings. Additional benefits from the cost savings include the council being able to put vital funds towards much-needed projects in the community. One bonus of Mr Sowden designing and installing the system himself is that he now has extensive knowledge of the installation, which will be of great benefit as he is also responsible for servicing and maintaining
the system in years to come. Mr Sowden told H&V News: “This has been an incredibly successful project and goes to show what savings can be made with good system design, meticulous preparation and quality products, as well as effective teamwork. “These types of savings are essential for councils nationwide, which are struggling with cuts in funding and are looking to find ways of continuing to deliver high-quality services with less capital at their disposal. “Knowledge is vital, as is expertise, and the technical support and advice available from manufacturers is invaluable in helping engineers like myself solve installation issues and meet both the Building Regulations and end-user requirements at minimal cost.” THE LATEST PRODUCTS View new offerings online hvnplus.co.uk/products

Better business Meaning of contract terms, pump efficiency directive contract terms
Don’t get caught out over meaning of contract terms It is rare that issues regarding the status of construction drawings make it into the courts, but this is what happened in the case of Emcor Drake & Scull v Edinburgh Royal Joint Venture. Emcor had been engaged under a subcontract to carry out plumbing and heating works as part of the construction of the New Royal Infirmary of Edinburgh. The dispute arose when Emcor was then invited to enter into another subcontract for the installation of electrical services. The subcontract stated: “Our bid has been prepared on the understanding that the vast majority of tender drawings received are fully co-ordinated and approved for construction.” Emcor claimed this meant the design of its works was complete and further drawings were not necessary, but Emcor had to carry out substantial detailed design work involving the preparation of working or installation drawings. It brought proceedings in the Outer Court of Session in Scotland involving a claim for damages of almost £4.75m for breach of its subcontract, since the tender drawings were not “fully coordinated and approved for construction”, as well as payment of almost £1.5m for variations. Emcor’s claim rested on the meaning of “fully co-ordinated and approved for construction”. The judge examined the processes involved in the design of the various engineering services for a complex building such as a hospital. Traditionally the building services specialist subcontractors coordinate the installation work in detail; this involves defining the precise routes taken by the ducting or piping for the different services 36 11 December 2013
to avoid clashes, the organisation of junctions in such ducting or piping, and the manner in which one service passes over or under other services at such junctions. When the co-ordination process is complete, each specialist subcontractor will have prepared detailed working drawings defining where the service is to run, including heights and the components to be used including bracketry and other fixings. There were detailed protocols relating to design, drawing production and services co-ordination in the subcontract documentation. Emcor was required to develop the designs into working drawings for manufacturing, installation and record purposes; if changes were required to the indicated line and level of the installation to effect a fit within the building, Emcor’s tender was to allow for this and any subsequent effects. Obvious meaning
The drawings produced with the tender package were design drawings rather than working drawings; this must have been obvious to Emcor, the judge said. The subcontract documentation envisaged two stages of coordination of services drawings. The first was the responsibility of the services engineer, who was required to “spatially co-ordinate the services with the structure only in producing design drawings”. The second was Emcor’s responsibility; Emcor was required to produce detailed working and installation drawings to enable its employees to install the services (detailing elements such as types of fixings and components).
Therefore, “fully co-ordinated” referred to the first stage of co-ordination by the services engineer. “Approved for construction” simply indicated that the relevant drawings had attained final release status; further revisions would not be required except in some minor aspect. If you are given drawings described as “fully coordinated” or “approved for construction”, always check what they mean, since they could affect the scope of your responsibilities. rudi Klein is chief executive of the Specialist engineering contractors’ (Sec) Group
meeting the new hydraulic pump energy directive The European Commission’s Energy Efficiency Plan aims to cut the energy consumption of products. The EEP has continued to mark out key cut-off points for manufacturers to bring their products in line with the latest standards and this year sees the introduction of the Minimum hydraulic Efficiency Index (MEI). The EC has developed a methodology to determine mandatory minimum efficiency levels for some electronic product groups sold in the EU, known as European Minimum Energy Performance Standards (EU MEPS). That list of products now includes clean water pumps. Because 80 per cent of a product’s
Products with lower efficiency levels will not be eligible for CE marking”
energy-efficiency is defined during design, it is precisely this part of the production process that is targeted by the EU MEPS. While pumps were originally exempt from the directive, they were later included when their full efficiency potential was identified as a major area of improvement. Pumps that now fall within the Eco-Design Directive include end suction own bearing pumps and end suction close coupled pumps, close coupled in-line pumps, multi-stage vertical pumps, and multi-stage submersible pumps. The EC evaluated existing pumps on the market to identify those which are not performing in line with the new criteria. The MEI identifies a minimum efficiency cut-off for those pumps performing under the new hydraulic efficiency levels. The first cut-off point was 1 January 2013, while the second more stringent one will come in on 1 January 2015. Products which have lower efficiency levels than the new requirements will not be eligible to carry a CE mark, making it illegal to place them on the open market anywhere in the EU. All pumps placed onto the open market in Europe must perform at a minimum level of efficiency, calculated at the BEP, PL and OL operating points, to meet or exceed the MEI Index of 0.1. Pumps placed on the market by the manufacturer prior to the enforcement of the new directive can be sold by the distribution chain and put into service by the end-user legally. Despite this, contractors and installers should be looking to bring their business practices in line with the new laws as soon as possible. The easiest way to prevent being caught unprepared is to start purchasing and installing compliant pumps straight away.

Better business: technical Thermal stores, smart metering heating
Thermal stores help get the most from renewables
Smart metering offers opportunity on performance
A crucial part of getting the most from renewable energy is suitable energy storage. Storage is affected by many factors, including the storage medium, the size and shape of the storage vessel and insulation properties. There is much industry chatter about electrical direct current storage and inter-seasonal stores. As everyday solutions, the former, although practical, is still in development and may be so for some time. The latter, which would theoretically store heat from summer to winter, is currently impractical due to the physical size and the difficulties of minimising heat loss over time. There are various ways to store heat, but water, as well as being the most economical, also has extraordinary properties of thermal storage. It’s reasonably energy dense and can store large amounts of energy by volume.
Building performance evaluation (BPE) is here to stay, with the government moving towards a 20 per cent reduction in costs for its built estate and an increasing unwillingness across the industry to accept design predictions as sufficient to prove outcomes. In the housing sector, regulation is increasingly focusing on proof of performance (airtightness, for example) and providing owners with objective labelling of homes. All this is happening at the same time as measures to fully introduce smart metering by 2020 are coming on-stream. Smart meters should help with the BPE of both commercial and non-commercial buildings, but how realistic is the objective?
However, for thermal storage to work effectively, what we must have is an adequately sized store. There needs to be a balance between its ability to hold a large enough amount of energy and being practically sized. If well designed and produced, a tank not much bigger than a Smart car, 2900 mm long, 1700 mm wide and 1600 mm deep, could easily hold up to 42 kWh over a moderate temperature range. If constructed from fibre glass with an inner and outer skin and insulated with 200 mm of polyurethane, it would only lose around 3 kWh per day even in the worst case scenario of mid-winter. Connected to a solar thermal system offering up to 14 kWh per hour in summer, or around 6 kWh hvnplus.co.uk
in winter, this would be sufficient to heat an average family home and supply adequate hot water. Question of circumstance
When sizing a thermal store, the heat requirement of the building and its occupants should be considered. For example, an average row of family houses might require a room temperature of 21 deg C, whereas a sheltered housing scheme might require 23.5 deg C, so size of thermal stores would vary for this. The key to calculating the correct size of a thermal store is working out the amount of heat required to heat a building and provide hot water. This should be balanced with the economics of replenishment. The optimal shape for a thermal store would be spherical, as this offers the minimum surface area for heat loss. However, as thermal stores are most often buried, a cube shape is generally the most practical solution. Thermal stores really are an effective implement for futureproofing against the rising costs of heating and hot water and, as they need no ongoing maintenance, whole-life costs are excellent. If you are able to collect heat energy economically then storing it in a thermal store will allow you to remove the peaks and troughs of usage. Thermal stores enable renewable energy systems to deliver affordable heat and hot water, reducing carbon footprints. mark Wozencroft is managing director of minus 7
The smartness of smart
Just how ‘smart’ is smart metering? At its lowest level, the smart meter simply offers a remote display of energy use (often expressed in £) so that users are sensitised to consumption. Rarely are both gas and electricity monitored. More commonly, ‘smart’ means that meter readings are transmitted back to the supply
Until the tangle of issues with privacy and smart metering is resolved, there is little alternative to expertly run BPE activity”
company on a scheduled basis. This is the type currently planned to be used in the smart meter roll-out. Again, it is unlikely that all services are monitored and the data is often collected at no more than half-hour intervals. Finally, there is the possibility of the ‘really smart’ meter, which permits full two-way communication between utility and user, thus bringing into reality the possibility of sophisticated demand management options for the power companies. This potentially could be a rich source of data for BPE, but ownership of the protocols and access rights are likely to be a serious hurdle to third parties. Data factor
Access to large volumes of user data is one crucial requirement to understanding just how the various interventions in existing dwellings or the application of new regulations in the built environment sector are working. The Department of Energy and Climate Change has developed a restricted-access National Energy Efficiency Data Framework and this has proven invaluable in understanding the impact of certain measures, such as cavity fill retrofits. Unfortunately, this kind of data is not available to the wider research community, nor is it fed from real-time or near real-time sources. This makes it unsuitable for use in the analysis of individual properties. We want to really deliver truly low energy (and carbon) buildings that are also healthy, productive and comfortable to use but, until the tangle of issues associated with privacy and smart metering are resolved, there is little alternative to detailed and expertly run BPE activity.

Boosters, fans, boilers, heat pumps DAB Pumps Boosting units DAB Pumps has launched the e.sybox, a water pressureboosting unit with an ergonomic design that brings a ‘plumb and play’ dimension to installation, saving time and money. It can be fitted vertically or horizontally on its anti-vibration mountings or onto a wall. The unit has variable positions for inlet and outlet pipework and can be plugged directly into the mains electricity supply. Once switched on, it automatically commissions. All the tools the installer needs are kept neatly in the lid of the unit, along with a useful QR code that links directly to an online how-to video. The LCD high-resolution display is adjustable and the user-friendly interface makes it possible to access performance information and customise the main settings. www.dabpumps.co.uk
