Capable of offsetting typically around 30% of the energy demands for water heating, solar thermal systems are ideal for organisations that rely on large amounts of domestic hot water (DHW).

For the existing buildings, 80% of which are still expected to be in use by 2050, the application of solar thermal pre-heat is a well-established means of reducing demands on prevalent gas-fired water heating helping to offset operational costs but actively cutting carbon emissions from the buildings. Commercial new builds or refurbishments, however, are either mandated or opting to shift to direct electricity are finding that move comes with a new financial burden as electricity remains substantially more expensive to operate than gas – currently by a factor of 3.8. Undisputed carbon and cost savings mean we are seeing a definite upswing in interest for new solar thermal systems with a ten-year return on investment being very achievable.

A correctly designed and sized system will consider the daily usage and peak demands. Its aim is to serve all peaks from storage, with the size of the peak determining the size of pre-heat. The recovery time for peaks is what ultimately determines the number of solar collectors a building requires. The design process also sizes usage with available space. A south-facing and unobstructed roof with an inclination of 30° from the horizontal is optimal, though by no means essential as modern solar collectors can be installed in a variety of permutations. Unsurprisingly, solar thermal collectors do suffer if the building is significantly shaded, in which case a commercial air source heat pump may be a preferred option to produce low-carbon heat.

Modular, high-performance flat plate collectors can be situated on or integrated into flat or sloped roofs, as well as mounted on a building’s façade. By far the most efficient way to heat water with solar energy, flat plate collectors offer a smaller footprint compared to equivalent solar photovoltaics (PV) for DHW. A typical 4 kW PV system requires approximately 16 panels covering 25m² of roof to match just three flat plate collectors covering just 6.6m² roof area. This makes solar thermal a prime choice when roof or facade space is limited.

Adveco collectors feature a copper meander absorber through which passes the solar fluid (glycol). The fluid transfers solar energy as heat to the system’s water via an indirect cylinder. To correctly manage solar fluid drain back technology should be applied to protect the fluid from overheating. This can ‘cook’ the fluid to a tar-like consistency causing permanent damage to the collector. As the name implies the solar fluid drains from the collector to a reservoir when not in use. Flat plate collectors with an integrated drain back module offer a more cost-effective (as there is no requirement for large solar storage) and more efficient (as there is no call to dump unused heat) approach. The technology has proven itself in the field with fluid changes required perhaps once in eight years, rather than the expected three.

For new build properties with electrical connection, the gas water heater is replaced with an electric boiler and cylinder to supply the afterheat which raises system temperatures to a necessary 60°C. This hybrid approach maximises the solar thermal input, typically offsetting 30% of the electrical demand, although it could be more depending on location. Adveco has simplified this hybrid approach by integrating a packaged FUSION E electric water heating system. This also gives the option of adding an electric immersion to the system as a backup for enhanced resiliency when assured water heating is a business-critical service. The all-electric solar thermal approach further reduces carbon associated with grid electric systems and aids in lowering operating costs.

This hybrid approach can be further extended with the inclusion of air source heat pumps to provide the initial pre-heat for the system. Operating at lower temperatures with the cold feed maximises the efficiency of the heat pump, reducing electrical operating costs and raising working flow temperatures from 10°C to 40°C. This is not hot enough for commercial applications, so the pre-heated water is then passed to the mid-solar thermal system. Essentially free to operate, the solar thermal system boosts the working flow temperatures from 40°C to at least 50°C. Although not operating at maximum potential, there is enough advantage gained from solar thermal to warrant the additional system complexity and capital investment. During summer months it is possible for the solar thermal system to deliver the necessary 60°C working flow for safe provision of commercial hot water. But to ensure safe, consistent, and necessary high operational temperatures, the water is passed to the FUSION electric water heater. Here final consistent water temperatures of up to 65°C are assured year round.

To date, Adveco has designed and supports more than 800 live solar thermal systems across the UK and such hybrid approaches are unavoidable if commercial projects seek a sensible, practical, and cost-effective path to low-carbon hot water.

Timber construction is undergoing a remarkable transformation, evolving both in quantity and quality. Today, timber structures are reaching unprecedented heights, towering as authentic skyscrapers, surpassing 20 stories and nearly 100 meters in height. At the heart of these timber giants, you’ll find Rothoblaas screws, pioneering this evolution with innovative solutions that were once unimaginable. Their latest catalogue, “Screws for Timber and Terrace Joints,” presented to 70 Area Managers from over 50 countries on early September 2023, introduces larger and more advanced screws designed to meet the demands of imposing structures and leverage new materials and engineering solutions, enhancing the strength of future timber constructions.

Revolutionary Timber-to-Concrete Joint System: TC FUSION

As we push the boundaries of timber construction, a significant challenge arises in creating rigid floors capable of spanning large distances between load-bearing columns. Rothoblaas has addressed this challenge with the groundbreaking TC FUSION system. Previously, full-threaded screws for timber (VGS, VGZ, and RTR) have now received certification for concrete. This innovation involves applying these screws before concrete casting, resulting in incredibly rigid and infinitely scalable timber-cement-timber joints, directly on-site.

In response to the evolving complexity of construction sites, often involving concrete, metal, and various timber types, Rothoblaas’ new catalogue offers a wide array of screws tailored for hybrid structures, including timber-to-concrete, timber-to-metal, and hardwood-softwood connections.

Transforming Timber-Metal Relationships

The traditional relationship between timber and metal has also evolved. Metal, once primarily used for thin slabs in roofing, is now increasingly part of the load-bearing structure. The catalogue focuses on optimizing self-drilling screws for connecting timber to metal structures, timber-metal-timber structures, and metal-to-metal connections.

Considerable attention has been dedicated to addressing corrosion concerns, whether from environmental factors, metal-to-metal interactions, or wood species-specific corrosion. The catalogue introduces a diverse range of anti-corrosion materials, offering solutions that balance cost-effectiveness with extreme condition durability.

Embracing Lighter Timber Structures

Timber frame and wood truss construction, traditionally prevalent in North-Central Europe, North America, and Great Britain, are gaining popularity worldwide, including in Southern Europe. To accommodate these lighter structures, the catalogue introduces the TBS Frame and TBS Softwood families, along with new sizes of the VGZ and HBS screws.

Enhancing Screw Performance with 3

THORNS Tip

Rothoblaas has improved the performance of many of its screws with the implementation of the 3 THORNS tip, featuring raised slitting elements and an umbrella thread. This innovation ensures quick initial grip, easy installation, and reduced torsional stress on the screw while minimizing damage to the timber.

An Expanded Catalogue for a Changing Sector

The latest catalogue from Rothoblaas spans 420 pages, a 10% increase from its predecessor. It introduces 18 new screw families and 18 range extensions, totalling approximately 450 new product codes. These additions anticipate emerging trends in timber construction, bridging the gap between traditional distinctions like carpentry, structures, and exteriors. A single screw can now serve multiple purposes effectively.

Beyond the Catalogue

Rothoblaas is not only revolutionizing timber construction in its catalogue; it’s also advancing its production. A new Italian factory, inaugurated recently, further strengthens the development, production, and distribution of Rothoblaas screws and connectors. With design originating in South Tyrol, production taking place in Italy and around the world, and exports reaching every corner, Rothoblaas ensures quality with each screw, backed by a unique identification code guaranteeing supply chain traceability.
In addition to the catalogue, Rothoblaas presents the “Smartbook Timber Screws,” a concise volume of 70 pages that packs 700 words of knowledge. This compendium, drawing from 30 years of timber connection experience, covers essential topics such as timber corrosion, shrinkage, swelling, fire resistance, applications, materials, and proper installation. It’s a valuable contribution that Rothoblaas offers to the timber construction world.

In conclusion, Rothoblaas screws not only connect materials but also bridge entire worlds. Their latest catalogue represents the pinnacle of innovation in timber construction, pushing the boundaries of what is achievable in this dynamic industry.

M-AR Offsite has partnered with Biffa, the UK’s leading sustainable waste management company, to ensure all waste generated through its manufacturing and construction operations is reused or recycled.

Through the partnership M-AR is refreshing its current waste management programme with the aim of diverting 100 per cent of its waste from landfill. The new Biffa skips in place around M-AR’s factory have clear signage as well as being colour coded to help visually identify what waste goes in which skip. It also creates a clear central focal point for waste management in the factory, which along with M-AR’s newly appointed ‘Waste Champions’, is designed to maximise take-up among staff.

Tom Malcom and Jamie Leckenby, who are both part of M-AR’s internal logistics team, nominated themselves to be M-AR’s first ‘Waste Champions’. The role involves educating the team and communicating policy changes to the whole production team. They will both receive specialist training and support from Biffa to appreciate the benefits of segregating waste effectively.

M-AR has also invested in upgrading its internal bins, moving away from the plastic 1100ltr bins which can easily become damaged, to a more robust steel tipper skip. As well as being more durable and therefore safer, these will also vastly reduce the number of trips previously required to load onto fork lift trucks and dispose waste into larger skips.

Working in partnership like this will see Biffa and M-AR collaborate on future waste reduction initiatives to implement within the business. M-AR will also be able to accurately report on waste volumes and disposals to track ongoing progress and understand where changes may need to be made to the process through its own online Biffa portal. The signage boards placed around the factory, as well as acting as prominent reminders about segregation of waste materials, will be used to provide feedback to the factory from the data collated from the Biffa portal.

Dan Lowther, head of procurement and supply chain at M-AR said:

“While this first phase covers waste management specifically relating to our manufacturing facility in Hull, our ultimate aim is to roll the programme out to all our live construction sites across the UK. This step marks a significant improvement in the reduction of waste generated on construction sites which are typically harder to regulate than a controlled factory setting and will mean that we’re able to divert all waste material from landfill whether that’s generated in the factory or on site. Reducing our waste materials to zero is a key part of our ongoing commitment to achieving net zero status as a company and reducing the embedded carbon of the modules we manufacture and install.”

 

Shaun Williams from Biffa’s commercial team in Humberside, added:

“We know recycling and sustainable waste management is extremely important to companies of all sizes, so we’re delighted to be working with the team at M-AR to bring our knowledge and skills to drive sustainability at their factory.

“Small steps can make a big difference, and recycling more waste means there’s less consumption of raw materials and fewer carbon emissions, which all contributes to the UK’s effort to achieve net zero.”

Offsite Home: ZenniHomes

Utah is facing a major challenge when it comes to the cost of housing. Homeownership is becoming increasingly unattainable for average workers, and rising rents are making it difficult to find affordable apartments. This issue has been a point of contention in recent mayoral debates in Salt Lake City, and it has caught the attention of Governor Spencer Cox, who is urging cities to find solutions to increase the housing supply.

To address this pressing problem, state and local leaders, academics, and developers recently gathered at the Innovations in Housing Affordability Summit at the University of Utah. One potential solution that was highlighted at the summit is factory-built housing. According to researcher Dejan Eskic, 77.2% of Utah households cannot afford a median-priced home. Additionally, a report from Ivory Innovations, a nonprofit arm of Ivory Homes, revealed that the United States had a deficit of 3.8 million housing units in 2020.

Factory-built housing involves constructing homes in factories with the use of steel, automation, and 3D printing technology. This approach offers several advantages. It allows for high-quality, quickly-built homes that generate minimal waste and pollution. Factory-built housing is also less constrained by the limitations of a tight labor market, short building seasons, and the need for variety.

Companies across the Mountain West are setting up factories to expedite the delivery of much-needed housing units. ZenniHome, for example, is developing modular homes that utilize steel and advanced technology. These homes are designed to be stackable and transportable. Other examples of affordable housing projects using factory-built modular homes and apartments have been successful in cities like Seattle and Mesa, Arizona.

Despite the many benefits of factory-built housing, navigating the complex web of state and local laws remains a major hurdle. However, Salt Lake City has taken the lead in adopting off-site construction standards, making it easier to bring factory-built units into the city. Efforts are also being made by the Utah League of Cities and Towns to support this innovation by addressing regulatory challenges.

While progress is being made, there are still concerns about ensuring that cost-savings from factory-built houses are passed on to homebuyers. It is hoped that new rules and regulations will be introduced during the upcoming legislative session in Utah to support and expand the use of factory-built homes as a solution to the state’s affordable housing crisis.

Paul Murrell

 

With just over a decade left on the clock, Paul Murrell, project director, nuclear & power at AtkinsRéalis discusses how a digital and data-centric approach will be fundamental in transitioning to a zero-carbon energy system.

 

 

The biggest upgrade to the UK’s electricity generation and HV grid is currently underway, moving the country towards a more affordable, home-grown, secure and cleaner energy system. The infrastructure requirements to deliver clean energy into our homes and businesses are immense and involve a design and build rate on a scale not seen for a generation.

Analysis we published earlier this year predicted the UK will need to build 12-16GW of new generation capacity each year between now and 2035 to hit decarbonisation targets. That’s equivalent to building Ireland’s entire energy system each year. Over the last 20 years the largest amount built and connected in a year is 6GW and we’re currently falling short of the minimum build rate that’s essential, not just for decarbonisation, but for security of supply and affordability.

It’s an unprecedented challenge and one that may not be achievable without a digital and data-centric approach that optimises programme delivery and design integration. By transforming and modernising the way the new physical infrastructure is designed, delivered and operated, it will not only speed up the build rate, but provide significant efficiency and cost savings over the assets’ lifetime.

Accelerating asset delivery through design automation

We can look to other complex infrastructure projects, such as those in the rail sector, for inspiration.

In 2014, spurred on by growing capacity issues and funding constraints, the UK rail industry embarked on the biggest upgrade to the rail network since the Victorian age. Digitalisation was core to its strategy and projects such as the East West Rail and HS2, heralded a new era of digital design.

Design and virtual modelling tools were used to model the construction and commissioning phases very early on in the design process and helped reduce the project delivery time by around 12 months, compared to more traditional routes.

Applying 4D design and integration of metadata with asset management tools also means clients have access to a comprehensive digital reference of all their assets, providing further savings post design and construction, if modifications are required.

Modern methods of construction also present an important way to save time, boost efficiency and reduce carbon footprint in the build stages. This might be using offsite modular fabrication approaches, 3D printing and precast parts, as well as innovative onsite techniques and new materials.

By automating design, costs may also be significantly reduced through replication. This has been central to the UK’s nuclear new build strategy, for example using data from the design and build of Hinkley Point C to inform plans for the proposed Sizewell C power station to drive down costs and schedule risk.

Other tools such as digital twins are also increasingly being used to underpin understanding of systems design and operational changes. By creating a virtual model, it is possible to assess impacts of change on system performance, effectiveness and efficiency and therefore reduce operational costs, as well as risks before any physical changes are implemented.

Regulation approvals and planning permission often proves a key step to ensuring timely and optimised development. It can take many months and often will dictate the critical path, if not managed collaboratively and effectively.

While not a ‘magic pill’, we are also helping clients successfully use advanced digital modelling to help secure buy-in during the vital planning stages and public consultations. For instance, a digital, interactive model could be used to help convey the potential impact of a new piece of infrastructure to local communities and planning authorities.

Using a planning led approach to infrastructure design can help select appropriate routes for infrastructure such as cabling and overhead lines, in the same way that has been used for rail routes.

Longer-term gains

Simulations and visualisations, digital technologies such as machine learning and wider digitisation of the grid will also provide long-term gains outside the design phase, enhancing asset management and operations and maintenance practices.

Data capture and AI for example might be used to provide comprehensive insight into an asset’s performance, and facilitate a more proactive, predictive and preventative approach, improving safety, efficiency and reliability.

Virtual replicas can also be used by engineers to explore complex and restrictive areas before going onsite, through a VR headset or mobile device. This can reduce the duration of their planned activities, minimise costs and improve safety.

Data-driven collaboration

Poor information management can be responsible for a high number of issues in design, construction, and operations. If the supply chain does not have access to the information it needs to make timely decisions, it may result in a potentially costly delay.

Major projects generate terabytes of data, and so it is becoming essential to have secure, common data environments to store, sort and interact with. This should provide a single source of the most up to date information needed by the multidiscipline teams involved and used throughout the entire project life cycle.

In addition, advanced data-driven programme management tools and interactive dashboards help to present programme and performance information, enabling better management decisions and improving risk management.

To realise the full potential of all these digital tools however, whether in the design, planning, build or operational stages, will require greater collaboration. Stakeholders and contractors, working right across projects need to be open to sharing their data and insight, so the right decisions can be made, and the best outcome achieved.

All to play for

By adopting a digital and data-centric approach for the design and delivery of the country’s new energy infrastructure, the UK has a chance to become a leader in the green energy transition. More digitalisation, deployed at pace, will not only accelerate the build, but generate a safer, more efficient energy network that will serve us for many decades to come.

The National Infrastructure Commission for Wales (NICW) has recommended ways to maximise renewable energy generation and help the country meet carbon targets.

The NICW called for an “immediate review” into building regulations that would see all new housing developments fitted with solar panels and batteries to store excess energy.

The extremely low cost of both solar thermal and photovoltaic technologies is one of the reasons the NICW suggests mandating them on newbuilds.

According to the International Energy Agency, the cost of solar has plummeted in recent years because of improvements in panel technology. This has led to a higher percentage of sunlight being converted into electricity. In the early 1980s, the average cost of solar panels was around £24 per watt. Today, it is less than £0.40 per watt – a 98 per cent cost reduction.

The NICW said that solar thermal technologies in particular can make a sizeable impact on buildings with high demand for hot water, such as leisure centres, swimming pools and care homes.

It also said it had received evidence that housing developers were “banking” projects that were not advanced in the development process so they did not need to comply with modern energy efficiency requirements.

To avoid this, “any potential loophole in the transitional arrangements must be closed to ensure that the new developments comply with the highest standards”, it said.

It suggested introducing a sunset clause that would apply the latest energy efficiency requirements to projects that have not been developed in a “timely” fashion.

The NICW also called on the Welsh government to present a plan for Welsh energy leading up to 2050 and revamping the energy grid.

Dr Jenifer Baxter, deputy chair of the Commission, said:

“We are now facing a time in our history where if we do not make a concerted effort to change how we deliver new infrastructure then our ambitions for net zero and the wellbeing of future generations will be in jeopardy.”

Aleena Khan, NICW commissioner, said:

“As a young person, I understand the importance of Wales acting decisively in tackling the climate and nature emergencies. I hope the Welsh government will consider each of our proposals carefully and the impact they will make on us meeting our energy and carbon targets.”
