AECOM, a major global player in the building engineering services consultancy arena, has concluded a report showing that continuous flow water heating systems have a clear advantage in terms of initial capital costs as well as life cycle costs over 20 years, when compared with stored hot water systems*.

The ‘Life cycle study of continuous flow water heating systems’ shows that continuous flow water heating systems can be up to 7% more economical than equivalent ‘traditional’ stored hot water systems.

AECOM was commissioned to carry out a life cycle study on continuous flow water heating systems, and to provide a comparison with conventional storage systems. Two case studies were provided that are based on projects using continuous flow water heating systems.

AECOM then determined an equivalent storage based system for each case study and compared operational and capital costs.

For the life cycle comparison, the analysis period was 20 years, based on the expected service life. The net present value (NPV) calculation is based on a discount rate of 3.5% (The GREEN BOOK – HM Treasury), an inflation rate of 2% for servicing costs and projected retail fuel costs from DECC1.

In both case studies the continuous flow system showed a clear advantage in terms of initial capital costs, as well as life cycle costs over 20 years, with the continuous flow system consistently lower in energy use than the two storage systems.

Case study 1

This was a system for a typical, small, pre-fabricated fast food restaurant. It is assumed the system only serves the hot water demand.

The life cycle analysis includes the initial capital costs, projected annual fuel costs, and estimated annual servicing costs which are assumed to increase by 2% each year. The annual fuel cost assumes the same daily fuel consumption over the whole year.

The servicing cost is based on £130/year per boiler, and £160/year for a boiler and cylinder. The resulting net present values of the three showed that the continuous flow system is 6 – 7% lower than the two storage systems based on that 20-year analysis period.

Case study 2

This was a system for a shower block in a holiday camp, with six showers and four basin taps.

For the continuous flow option, the analysis is based on a configuration of 4 continuous flow water heaters that each have a nominal output of 48 kW, which, for this particular application, because there is a very short run of pipe work between the water heaters and the fixtures, it is possible for the water heaters to generate water at 40°C. The risk of legionella is overcome by regular flushing of the system.

For the energy required to deal with the instantaneous hot water demand the analysis assumes that the bulk of the hot water demand would be due to the showers. Each shower would typically have a flow rate of around 9 litres per minute, which if mixed to 40ºC would equate to an instantaneous load of around 19 kW each, so even if there was only one shower running, the load on a single continuous flow water heater would equate to an efficiency of 95% based on the performance curve. As the hot water demand increases, the modular nature of this particular configuration would allow the 95% efficiency to be maintained for the bulk of the demand.

The difference in daily fuel costs between the three systems is around 7%. The usage profile for this case study is particularly suited to continuous flow systems (i.e. high but infrequent demand over the day), which is why there is an advantage in fuel consumption over the storage systems.

Systems employed in the study

*Indirect fired storage systems
This consists of separate heat source and storage cylinders, where for this study the heat source will be gas fired boilers running on 80ºC flow and 60ºC return with gross efficiency of 89%. As the hot water is stored at 60ºC in insulated cylinders there will be standing heat losses. The standby electricity is assumed to be 15W per boiler, and 60W when operating to cover fan and controls.

Direct fired storage systems
This is where the hot water storage cylinder has an integral gas burner to directly heat the water, and the key difference with indirect fired storage systems is that they are designed to operate in condensing mode and generally achieve gross efficiency up to 96%. A disadvantage of direct fired storage systems is that the standing losses are around 3 times higher than indirect storage cylinders.

Continuous flow systems
This is essentially a gas boiler that is designed to instantaneously heat mains water for supply directly to water fixtures without any storage. The key advantages with this type of hot water heating, is firstly saving in space needed for hot water cylinders and the associated standing heat losses. The challenge is that instantaneous hot water demand can vary hugely for most systems and therefore the continuous flow heating system needs to have a wide modulation range as well as maintaining efficiency over that range.

There are several misconceptions about LED lighting, principally that LED lighting prices will go down so it pays to wait; LEDs are so efficient that controls are unnecessary; and that LEDs don’t work well in high-temperature environments.

According to the Energy Savings Trust, LED offers best value for money in lighting today; the price of fittings has come down and, at the same time, performance has improved significantly.

The Carbon Trust advocates LED as its number one efficiency recommendation. LeaUnknown-2ding website www.environmentalleader.com reports that while switching to LEDs creates a one-time savings event – typically reducing lighting energy use by up to 50% – integrated sensing and controls can nearly double those energy savings, making controls essential for maximum savings and project economics.

And did you know that by using LED in construction, it significantly contributes to the BREEAM rating of a building as it typically halves energy consumption of traditional light sources. Miniaturisation has also led to a significant reduction in raw materials utilised in manufacture.

Artificial lighting in buildings is usually categorised in three ways. The ‘Ambient’ lighting function provides light to the space to an accepted level. ‘Accent’ lighting highlights certain features and/or attributes. ‘Task’ lighting illuminates specific working areas to aid visibility.

Lighting Performance

The four key criteria governing LED performance are thermal management, optical control, efficacy of light and reliability of power. So, what are the guiding principles of best practice in quality manufacturing?

Heat has a negative impact on any LED light source’s performance. The next generation in thermal management dissipates heat away from the LED chip, providing higher quality, brighter light for longer.  There’s also been continuous improvement in efficacies of LED chips so the higher the lumens per watt, the better.

Look for products warranted to L70 to a stated number of hours.  This means you can expect a light output of 70% of the lumen performance stated at that period of time e.g., a 1000 lumen LED luminaire will deliver at least 700 lumens after six years, based on burning 4000 hours per year.

An emerging trend in construction is to insulate the ceiling void by ‘blowing in’ loose fill insulation as an alternative to loose-laid products. Loose fill completely encloses the fitting which could affect LED performance in inferior downlights.

 Biodynamic lighting

Light controls our biological or body clock and this is known as the circadian rhythm. New to the market, biodynamic LED lighting allows people to control their environment according to need, mood and task, which can improve performance and motivation. Changing the colour temperature of the artificial lightsource (e.g. from extra warm to warm through to cool) can have a dramatic effect. Biodynamics is particularly suitable for dynamic interior projects, retail applications, and in healthcare and homes for the elderly.

 Regulatory compliance

Lighting design is a complex issue and part of a quality manufacturer’s role is to develop bespoke schemes which will comply with regulations. A revised version of the Building Regulations, Part L (2013), came into force in April 2014. BIM LEVEL 2 was introduced as a requirement for all government construction projects this April 2016.

Enlite’s LED value solution

The Aurora Group has responded to increased demand for LED by engineering the Enlite range of 250+ “Lighting Essentials”. Enlite offers Offsite’s varied modular business model the best in value, quality and performance to meet specifications and budgets.

Firm Enlite LED favourites in the MMC sector are the E8TM 8W integrated fire rated downlights with halogen like appearance, the ultra-slim E6060 TM 600mm2 flat panels for commercial applications, the UniPac TM and LinearPac TM IP65 linear anti-corrosives which replace traditional T8s and the vandal resistant Orbital TM IP66 bulkhead.

A house built using polyurethane materials consumes 85% less energy than a home built from conventional materials. They can provide very high levels of insulation with minimal thickness which in turn allows architects and designers to maximise the use of interior spaces. It is perhaps no surprise then that when it came to the construction of a passive house in Belgium, polyurethane insulation materials were used to create a highly insulating building fabric. Three years on, has the Polyurethanes Passive House in Brussels and its very well insulated and sealed envelope provided a comfortable and healthy environment throughout the year?

The end-of-terrace four-storey family house developed by ISOPA, the European trade body for diisocyanate and polyol producers, was completed in Evere near Brussels in 2013. It is now occupied and working as a low energy test bed, its running costs and energy use closely measured to show the savings possible for homeowners.

While there are over 12,000 new build Passive House certified buildings across Europe, the ISOPA house is unusual in using a high proportion of PU to achieve its highly insulating fabric first design which reduces the need for heating and saves around 80% of the energy used by a normal house. PU insulation has been used wherever possible from wall cavities to the floor, and windows to the roof.

The house has been designed so that all of the construction elements work together in an integrated way, from the solar panels on the roof to the geothermal heat pump and MVHR system which ensures that warm fresh air circulates internally despite the high air tightness levels. The University of Leuven has been evaluating the home’s overall performance, energy use and indoor comfort levels which would verify whether the PU products as installed were really achieving the calculated performance levels.

The analysis of the data yielded an estimated heat loss coefficient of 60.0 W/K, with a standard deviation of 3.0 W/K. This indicates that the thermal performance of the building fabric meets the very high standards expected, which was instrumental to the project reaching the performance levels required for Passive House certification.

Known for the comfort they provide, polyurethanes are ideal for Passive House construction because they provide very high levels of insulation thanks to low thermal conductivity, meaning they provide reduced thickness increasing their affordability and reducing the impact on building footprints. As well as requiring fewer adjustments to be made to the design of buildings and less aesthetic compromises such as with deep window reveals, further cost savings on depth of eaves, joists, rafters or studs, lengths of fixings can be achieved. In short, the extremely low U-values required for Passive House projects can be much more easily achieved with PU than with other materials as far fewer changes to design detailing are required.

Rigid PIR insulation boards are also light but strong, moisture-resistant and easy to install, and they, as well as spray foam PUR insulation, retain their insulating properties for the life of the building. Last but not least, PU materials contribute to preservation of natural resources by reducing the need for energy which assists their sustainability credentials in Passive House projects.

With a daunting 80% reduction in carbon emissions on 1990 levels called for globally by 2050, such efforts to create practical ‘near zero energy’ houses are essential. With houses accounting for 40% of energy consumed across Europe, achieving the means of constructing new Passive Houses affordably using PU which can deliver the results while saving homeowners money is the realistic way forward, as demonstrated at the Polyurethanes Passive House.

The total amount of tiles recycled by Armstrong Ceilings at the airshow has risen again.

Armstrong Ceilings continues to break the mould for recycling building materials at the Farnborough International Airshow.

The UK manufacturer has again exceeded the amount of ceiling tiles it recycles at the bi-annual show it has supplied for the past four events, this year some 14,769m2 compared to the 13,400m2 it recycled in 2014 – the first time the company employed its Off-Cut scheme as well as its End-Of-Life scheme.

Not only that, the amount of mineral ceilings recycled from the potential from more than 200 temporary corporate hospitality and business chalets and exhibition halls on site rose from 61% in 2014 to 79.8% this year, winning praise from the show’s head of operational development and Health and Safety.

Jonathan Smith said: “I am extremely pleased with the outcomes this year working with Armstrong. There has been a significant year-on-year improvement over the last few shows since we began working together.”

Some 1,885m2 (or 12.7%) of this year’s recycling total was from 70 bags of ceiling tile off-cuts recycled prior to the show between July 11 and 17 while 12,884m2 (87.3%) was from tiles dismantled after the show, all in all saving contractors (whom Armstrong does not charge for the service) more than £10,000 in landfill and skip hire tax.

In terms of environmental impact, as well as the 14,769m2 diverted from landfill, this year’s scheme saved more than 73 tonnes of virgin raw material, more than 20,000 kWh energy, more than 36,000 CO2 equivalent greenhouse gasses, and more than 251,000 litres of potable water.

The tiles for recycling (Dune Supreme and Fine Fissured) were collected in bags and stored in the exhibition hall then returned on nine trucks to Armstrong’s production facility in Gateshead for recycling back into the mix with the help of logistics company and fork lift operators Ceva Showfreight, specialist waste management and cleaning contractors Sagum Events and the Southampton branch of specialist distributor SIG Interiors.

The corporate hospitality and business chalets, which are used by such prestigious exhibitors as Lockheed Martin, Boeing and Rolls Royce, typically take five weeks to build and fit out and one week to dismantle.

Oliver Newin, who oversaw the recycling and environmental element of the show, which prides itself on its green philosophy, said: “We encourage people to use Armstrong because of their recycling capabilities and this year it went very well.”

Roy Smith, Armstrong’s recycling sales development manager, added: “Our recycling scheme was very well received by the contractors on site. I feel from them it is now an expected part of the show.”

Armstrong was first brought in to recycle its suspended ceilings at the 2008 airshow by the event’s largest independent chalet fitting contractor SDD I GES and back then saved 2,600m2 (or 10 tonnes) from landfill.

The ceiling tiles recycled from this year’s Farnborough airshow help to bring the total amount of recycling by Armstrong since 2009 to more than 500,000m2.

Armstrong pioneered ceiling recycling in the UK in 2003 and since then the programme has evolved to include all mineral tiles, no minimum quantities, a growing network of “Green Omega” installers and partnerships with national distributors to further support customers’ local recycling requirements.

Rinnai, manufacturer of the energy efficient range of Infinity continuous flow water heaters and a complete range of gas fired wall heaters, is providing a brand new heating and hot water solution to offices in Merthyr Tydfil, South Wales.

CST Renewables – the building services engineers – were keen to get to grips with installing a new system. This included a bespoke boiler and hot water heating package.

CST Renewables was established by Control and Service Technology in response to growing interest in the renewables market from clients looking to improve energy efficiencies and dramatically lower running costs. The company, based in the Welsh town of Bridgend, is an acknowledged specialist in the commercial market but also completes domestic installations, service and repair work.

The first UK installation of the Rinnai system was at a large office building where CST had been called to assess the best energy efficient replacement for a failing forced draught, flued modular boiler set up.

The old system was low efficiency and costing the client, a property leasing company, a substantial amount in repair bills annually. The building is rented to a variety of organisations and businesses such as call and administration centre businesses.

Mark Hillier-Rees of CST says: “It was obviously the site needed to move on to something more energy efficient. We removed the old boiler and replaced it with two new Rinnai boilers on a cascade system. The redundant flue was removed and we put in place the Rinnai co-axial flue.

“This new Rinnai system is highly efficient – and due to its lack of moving parts and easy maintenance has very low annual service costs.”

The large 100kW condensing heating boilers are ideal for providing heating to buildings such as the Merthyr Tydfil office block and are extremely flexible as they can also provide hot water when placed in a cylinder. The Rinnai boilers are also available in 50kW and 75kW sizes.

Chris Goggin, Associate Director, Rinnai UK comments: “There are clear benefits in terms of efficiencies, when considering heating and hot water as two separate systems. I am pleased that we can provide two high efficiency market leading products in one simple turnkey solution.”

For more information on the RINNAI product range visit www.rinnaiuk.com.

Rinnai’s latest innovation in the energy efficient fast delivery of instantly useable hot water is the Infinity Solo Re-Circulator water heater.

The Rinnai Infinity Solo condensing and low NOX water heater is the first of its kind for the UK to combine the advanced technology of wall mounted continuous flow water heaters with a stainless steel storage cylinder, all in one compact footprint.

The design parameters of this product empowers specifiers, designers, installers and engineers to benefit from unique Rinnai technology in applications it was once not previously possible. For instance, the Infinity Solo will have both 35kW and 54kW sized appliances, ensuring sites with a smaller gas meter can readily use this technology. The larger Infinity Solo model will also act as a high-efficiency alternative to gas fired storage appliances that exist in today’s market.

The cylinder is stainless steel and this reduces the weight compared to glass lined models, and it makes transportation and installation a lot easier. As well as the difference in weight, the cylinders also have extremely low heat loss figures (as low as 1.41kW/h day), so the user pays less to maintain the heat within the tank.

One other benefit of the Infinity Solo using a stainless steel cylinder is that the life expectancy of the material is far greater than that of a glass-lined equivalent as glass suffers from thermal shock causing it to crack after a period of time.

The Infinity Solo range is also renewables compatible and supplied pre-fitted with a coil, meaning that the primary energy source will always be from renewable gains and the complementary Rinnai water heater will only apply the precise amount of gas to boost the difference in temperature.

Rinnai manufactures the energy efficient Infinity range of gas fired continuous flow water heaters and space heaters. The Infinity brand carries the widest range of condensing water heaters on the market today with the most impressive efficiencies in operation, leading the field in technological innovation.

SPI are one of the leading manufacturers of expanded polystyrene in the UK, supplying an extensive range of building and civil engineering products. With state of the art moulding and cutting machinery SPI can offer a wide range of grades and bespoke products to suit all types of projects.

As an insulation supplier SPI have seen trends in correlation with the increasingly demanding building regulations of part L conservation of fuel and power. Even after the scrapping of the 2016 zero carbonpolicy there is still a requirement to meet the 80% reduction in carbon emissions by 2050 under the Climate Change Act. There has been a call for innovative solutions when it comes to insulating the UK housing stock, the development of building systems which produce lower target U-Values has allowed for off-site construction to bloom, with a growth of products like SIPs, ICF walls and modular floors.

Recently this has lead to an increase in passive house foundation construction largely developed as offsite modular concepts, which allows for less installation time on site meaning the structure above can be installed earlier. Typically the foundations and structure can be completed within a week for a 4 to 5 bedroom house. Passive house foundations consist of a basic L shaped perimeter with standard boards up to three layers thick. Specialist clips are used to hold the whole foundation system together. The complete foundation base is then covered with a DPM and the structural concrete can then be poured.

Once the concrete is cured the superstructure can begin. Most commonly we have seen these foundations used with SIPs and lightweight timber frameworks. As an insulation provider the off-site development means we can cut bespoke products required by the layout of the build quickly and easily, making the whole process from conception to completion exceptionally fast.

These types of building elements and forward thinking innovations offer a certainty that builds can easily exceed regulations which when coupled with the environmental sustainability expressions of modern future proof housing make the prospects of a carbon neutral 2050 attainable.
