“Government will drive renewables sector off cliff” warns CECA

A stark warning has been issued by the Civil Engineering Contractors Association (CECA) that unless the Government amends its current approach towards the renewables sector, the industry will “fall off a cliff”, resulting in job loss and lack of growth.

The warning came as a response to the Scottish Affairs Committee inquiry into renewable energy.

CECA say that renewables play a vital role in industry growth, and that there is currently over £300m of civil engineering activity per annum in the Scottish renewable energy sector alone, which is responsible for directly employing 3,000+ workers and supporting over 11,000 jobs. Backing up this statement, recent research published by the Scottish Government indicated that renewable energy generation alone in Scotland produces enough power to supply the equivalent of every household in the country.

CECA Chief Executive, Alasdair Reisner said “CECA has long argued that the UK Government must commit to a long-term energy strategy based on a diverse energy mix that does not deter badly-needed investment to enable a safe and secure energy supply.”

“The UK Government’s policy of removing support for the renewables sector is extremely disappointing, as the sector had been making substantial progress towards cost efficiency during the lifetime of this Parliament.”

“Policy changes to date will lead to substantial job losses within the industry and its supply chains. If those skills are lost, the challenge of rapidly reskilling the sector will be extremely costly.”

“We call on the UK Government to reassess its approach to the renewables sector, adopt an evidence-based approach to renewables policy, and recognise the role it must play in providing the diverse energy portfolio the country needs.”

How conflict influences architecture

Cities are busy, hectic and diverse places. When groups of different people are forced to live in close proximities, conflicts can understandably arise. How does architecture influence these conflicts and what role does it play in preventing them?

Metropolises are becoming centres for ethno-national and religious conflicts. However, architecture can make a distinct contribution to the problem through its own spatial understandings and practices as well as strategic planning and building policies. These issues are increasingly urgent and need to be addressed in view of the conflicts that we witness today.

Dr Wendy Pullan, Head of the Department of Architecture, Cambridge University and Director of the Centre for Urban Conflicts Research, will deliver the 2016 RIBA East Spring Lecture ‘Architecture and Urban Conflict: How do they connect?’

Across the world, cities are increasingly becoming centres for ethnic and religious conflicts. Although conflict is a subject that has preoccupied sociologists, geographers and political scientists, architecture is a relative late-comer to the debate. There is a clear advantage to a multidisciplinary approach, yet architecture makes a distinct contribution.

Destruction and devastation present unique opportunities to radically rethink our environment. Strategic planning and building policies can be found to enhance particular political views. Architecture is fragile, yet architects have the power to instigate change. This lecture will address these issues, focusing on work done by the Centre for Urban Conflicts Research at the Cambridge Department of Architecture.

Dr Wendy Pullan received the Royal Institute of British Architects‘ inaugural President’s Award for University-Led Research for work on Conflict in Cities.

The ‘Architecture and Urban Conflict: How do they Connect?’ Talk is part of a series of events based around the subject of the RIBA Exhibition ‘Creation from Catastrophe – How architecture rebuilds communities’, which explores the varying ways that cities and communities have been re-imagined in the aftermath of natural or man-made disasters.

Will 3D printing spark another industrial revolution?

First we saw hand-production methods, with highly skilled craftsmen wielding untold knowledge and expertise over the structural properties of material and the best way to implement them within a design. Then the industrial revolution changed everything, with machinery and complex equipment trumping traditional handiwork. As the digital age ticks on and technologies such as 3D printing ever improve, is the construction industry on the brink of yet another industrial revolution?

Development of 3D printing actually began in the 1980’s, however it wasn’t until around 2010 that the technology experienced a paradigm shift in opinion regarding its usefulness. Initially considered ‘newfangled,’ expensive and improbable to take off, the process of 3D printing soon began to grab the attention of avant garde architects, designers and progressive construction professionals worldwide.

The pros

In contributing to the built environment, 3D printing has thus far been used to create small, complex components to be implemented in a hybrid design of new and old methods and even to ‘print’ entire buildings. Chinese materials firm Yingchuang New Materials recently produced 10 3D-printed buildings in just 24hrs, using a custom-built printing machine that outputs layers of construction waste mixed with cement. See video below:

With government aims to end the housing crisis within a generation, could 3D printing exponentially shorten the ETA?

Other technologies that are rapidly developing within the sector are also abetting a future that will lean heavily towards 3D printing. Industry-wide use CAD and the rise in usage of building information modelling (BIM) in particular will enable greater use of 3D printing, as much of the information necessary to create a building via computer aided manufacturing will exist as a result of the design process.

3D printing would allow faster and more accurate construction of complex structures and components, whilst simultaneously lowering labour costs and waste production. It might also enable construction to be undertaken in harsh, dangerous environments previously unobtainable by a human workforce – expanding our horizons.

The cons

As well as a wealth of positives, there are equal concerns regarding a 3D printed future. Systemised construction has never been highly successful in the UK. There was a brief boom in panelised systems for high-rise apartment blocks and pre-fab housing following the Second World War, but frankly they were ugly, lacked character and were plagued with condensation problems.

Printers could also pose a threat to the existing workforce, reducing employee numbers throughout the industry, as ostensibly the 3D printer could do the majority of the work.

Currently, only a limited number of materials can be used, since the same printer might not be able to print the required multiple materials to deliver the rich and diverse built environment we all need to thrive. In addition, utilising the technology on a building site would require expensive and complex equipment, and whilst it is possible to envisage using some simplified version to manufacture specialist components on a more industrial scale, it remains debatable as to whether the method would offer an attractive return in comparison to bricks and mortar.

The bigger picture

Obviously 3D printing has infinite potential in a wide variety of areas outside of construction, such as creating clothing, instruments, prosthetics, art, food, tools and – controversially – weaponry; to name but a few examples. As it becomes easier for businesses to transmit designs for new objects around the globe via the medium of internet, the need for freight services, manual skills and traditional manufacturing and transport techniques might deplete massively. This would result in an entirely different culture; a society free from import and export which could ultimately make or break entire global economies.

American economist and Nobel Prize winner Michael Spence says “the world we are entering is one in which the most powerful global flows will be ideas and digital capital, not goods, services, and traditional capital. Adapting to this will require shifts in mind-sets, policies, investments (especially in human capital), and quite possibly models of employment and distribution.”

Rome wasn’t built in a day but perhaps one day it could be printed in one. We just may be on the brink of the next chapter in our commercial and industrial history, will you say “viva la revolución” or do you stand as a proud Luddite, protecting our current way of life against the influx of technology that could serve as a blight to us as a species?

Construction begins on Europe’s largest floating solar farm

Construction work has started on what will be the largest floating solar farm in Europe. Located at the Queen Elizabeth II reservoir near London, the project is part of a greater effort by Thames Water to source a third of its energy from renewable methods by 2020.

Once completed in March, the floating array will boast the impressive accolade of being the second largest of its kind in the world.

In excess of 23,000 panels will be floated on the surface of the reservoir water, generating enough electricity per year to power the equivalent of around 1,800 homes. Once complete, the finished array will cover around a 10th of the reservoir’s surface area – roughly the same area as eight Wembley-sized football pitches.

Thames Water has confirmed that the renewable electricity produced by the 6.3MW floating array will be used to power a water treatment centre nearby.

Energy Manager, Angus Berry said “Becoming a more sustainable business is integral to our long term strategy and this innovative new project brings us one step closer to achieving our goal – this is the right thing for our customers, the right thing for our stakeholders and most importantly the right thing for the environment.”

The installation will require over 61,000 floats and 177 anchors to keep the array above water and in situ, and is been delivered by solar energy company Lightsource.

Chief Executive at Lightsource, Nick Boyle commented that as an increasing number of industries quite rightly turn their attention to lowering their carbon footprint, the solar industry will need to develop new skills in order to ensure that future projects deliver maximum efficiency.

“There is a great need from energy intensive industries to reduce their carbon footprint, as well as the amount they are spending on electricity and solar can be the perfect solution. Therefore, constantly evolving new skill sets to ensure that all of our projects deliver maximum energy generation over the lifetime of the installation” said Nick.

Floating solar farms are considered an efficient way to maximise renewable energy generation in areas where land is scarce, by using the normally redundant surface area on reservoirs and lakes.

The largest floating solar array is currently under construction on a reservoir in Japan. Once completed, it will provide enough clean electricity to power nearly 5,000 households.

Advocates of the approach argue it can also reduce evaporation from reservoirs, while the cooling effect of the water is said to help improve output from solar PV cells.

News of the floating array follows the recent announcement that wind turbine towers are set to reach heights of up to 170m – almost as high as the Gherkin in London, in the near future. This shows that in the world of energy, renewables continue to power ahead in terms of growth and innovation.

Wind turbines set to reach mega heights with new techniques

Wind turbine towers are set to reach heights of up to 170m with new construction techniques and materials, according to wind power engineering specialists K2 Management. Tower heights have grown steadily over the last decade as operators seek stronger wind speeds higher up in the atmosphere.

Based on work with various clients across the globe, K2 Management believes new technology developments like modular concrete structures mean turbine heights are likely to soar to up to 170m in the coming years – higher than London’s ‘Gherkin’, and almost as high as the Eiffel Tower. This compares to the tallest towers of 150m at present. There has been a 48% increase in average hub height since 1999, and based on its experience in the industry and its partnerships, K2 Management has insight on how to manufacture hybrid tower concepts up to 170m.

According to K2 Management wind resource experts, a 3 MW turbine located in a forest area for example, with an average wind speed of 6 meters per second, will meet 13 percent more wind speed if the turbine height doubled from 70 to 140 meters. Annual energy yield prediction would increase by almost 30 percent because of less surface aerodynamic drag and the viscosity of the air.

Therefore, going up to 170 meters from 70 meters will boost energy yield prediction by 35 percent on average. The more complex the terrain – for instance forests, hills, mountain, buildings – the larger the impact is in using taller turbine towers.

K2 Management CEO Henrik Stamer says “170m towers could become a common sight in the near future in markets like the USA and Germany as part of a new renewable skyline. We expect to see more of these mega designs as we help our clients get the most out of their wind projects.”

Through its network of experts across the globe, K2 Management possesses a unique vantage point overlooking the wind industry, allowing for a view into emerging trends. The Company is able to draw on this wide breadth of experience to identify ways of making wind projects more efficient.

Stamer adds: “As a company that is at the global cutting edge of technology we are helping push the limits of the wind industry in terms of power generation efficiency, cost-effectiveness and return on investment; and these new mega wind turbine towers are a case in point.”

World’s largest concentrated solar plant opened in Morocco

Morocco has launched the first phase of the largest concentrated solar power (CSP) plant in the world. When fully operational, the plant will produce enough energy for more than one million Moroccan households.

Inaugurated officially by His Majesty Mohammed VI of Morocco, the solar plant underlines the country’s determination to reduce dependence on fossil fuels, use more renewable energy, and move towards low carbon development.

The three-plant Noor-Ouarzazate CSP complex called NOORo expects to achieve over 500 megawatts (MW) installed capacity, ultimately supplying power to 1.1 million Moroccans by 2018. It is estimated that the plant will reduce the country’s energy dependence by about 2 and half million tons of oil, while also lowering carbon emissions by 760,000 tons per year.

Concentrated solar power is such a promising technology that the International Energy Agency estimates that up to 11 percent of the world’s electricity generation in 2050 could come from CSP. This is especially true in the Middle East and North Africa, a region with abundant solar resources and high hopes of eventually helping to meet the E.U.’s demand for energy.

“With this bold step toward a clean energy future, Morocco is pioneering a greener development and developing a cutting edge solar technology,” said Marie Francoise Marie-Nelly, World Bank Country Director for the Maghreb, “the returns on this investment will be significant for the country and its people, by enhancing energy security, creating a cleaner environment, and encouraging new industries and job creation.”

Despite the potential of CSP, relatively high technology costs, when compared to fossil fuel alternatives, deter utilities from investing. Concessional and public financing were key to lift this project off the ground. The Moroccan Agency for Solar Energy, the government agency focused on the country’s solar ambitions, secured over $3 billion needed for the Noor-Ouarzazate complex from the African Development Bank (AfDB), the Climate Investment Funds (CIF), European financing institutions and the World Bank.

“This launch shows that the low-cost, long-term financing provided by the CIF can serve as the spark that attracts the public and private investments needed to build massive CSP production facilities at an attractive cost for countries interested in developing solar energy,” said Mafalda Duarte, Head of the Climate Investment Funds.

Trailblazing projects on the African continent, like the Noor solar plant, are proving the performance of CSP. As well as the environmental benefits, the plant results in new, local jobs, and can lead to a high-performing sustainable energy economic sector for Morocco.

Yacine Fal, AfDB resident representative in Morocco, said “Noor solar complex is part of the innovative operations of AfDB in the energy sector in terms of financing and technology. It stands to serve as an example for Africa and the world about how to create effective pathways to greener and more inclusive economies through renewable energy”.

From deprivation to dream homes

A panel will look at how the layout of deprived estates can be best regenerated and reused to deliver more quality homes for Britain.

New tenants rights will be at the heart of the regeneration of some of the country’s most deprived estates, Lord Heseltine said this week (9 February 2016).

A panel, who met for the first time today, will look at how the layout of estates can be best used to deliver more quality homes that people can buy and rent.

The experts will also ensure that there are strong protections in place for existing residents so they will always be given the right to return to their communities.

The 17-strong group, co-chaired by Lord Heseltine and Housing Minister Brandon Lewis and reporting to the Prime Minister and Communities Secretary Greg Clark, will develop a national estate regeneration strategy and work with up to 100 estates to tackle deprivation and transform them into vibrant communities.

The Prime Minister announced last month that £140 million would be made available to jump-start the regeneration. The loan funding will allow communities to lever in investment from the public and private sector to deliver ambitious projects that local people can be proud of.

Lord Heseltine said “Estates regeneration is key to transforming the lives of people living on poorly designed housing projects. The panel will provide expert advice, support and explore innovative funding solutions to drive forward the regeneration of estates around the country.”

“However, I am clear that this has to be locally led and we must work with the residents of such estates. I now want to see local communities coming forward with innovative ideas to achieve desirable neighbourhoods that local people can be proud of.”

Housing Minister Brandon Lewis said “We know these estates offer huge potential to be revived so that they become thriving communities and places which people want to live and work in.”

“This panel provides a wealth of experience to kick-start work that will help transform the lives of thousands of people by delivering better homes in better estates.”

The panel met at the York Road Estate in Battersea, London where plans are being developed for a major regeneration scheme.

Wandsworth Council leader and panel member Ravi Govindia said “I’m delighted to join panel and to play a part in unlocking the great potential of our country’s housing estates.”

“Here in Battersea we are demonstrating that estate regeneration can be done with the support of the local community. Our approach is centred firmly on improving the lives of Winstanley and York estate residents and to providing new opportunities and better life chances.”

Future meetings will be held at estates across the country. Members are:

  • Councillor Ravi Govindia, leader of Wandsworth Council
  • Nicholas Boys Smith, director of Create Streets, a social enterprise and independent research institute which pushes for well designed estates
  • Andrew Boff, leader of the Greater London Authority Conservatives housing group
  • Elaine Bailey, chief executive, from Hyde Housing Association, which successfully regenerated the Packington Estate in Islington
  • Paul Tennant, chief executive from Orbit Housing Association, which successfully regenerated Erith Estate in Bexley
  • Tony Pidgley, chief executive of Berkeley Homes – a lead partner on various estate regenerations across London
  • Peter Vernon, chief executive of Grosvenor Estates
  • Jane Duncan, president of the Royal Institute of British Architects (RIBA)
  • Ben Bolgar, director of Design Theory and Networks at the Prince’s Foundation
  • Dominic Grace, head of London Residential Development at estates agents Savills
  • Emma Cariaga from the British Land and Thames Valley Housing Association
  • David Budd, Mayor of Middlesbrough
  • Natalie Elphicke, chief executive of the Housing & Finance Institute
  • Graham Allen, MP for Nottingham North
  • Felicie Krikler, associate director at Assael Architecture

The group will now work with a range of local stakeholders, including communities, local authorities, landlords, investors, builders, housing associations, and anyone else with ideas and ambition. It will draw up the national strategy for estate regeneration by the autumn. Its objectives include:

  • providing strong protection for existing residents, such as rights of return
  • delivering more homes for rent and ownership
  • delivering homes more quickly
  • promote high standards of design to provide commercially viable schemes which have the potential to be self-financing
  • encouraging and attracting more private and public sector investment to help regenerate estates

Britain is building again with the number of new homes up 25% in the past year and revived estates will play an important part in providing good quality social and affordable housing, and offering people the chance to achieve their dream of home ownership.

Wandsworth Council has announced ambitious plans to regenerate the neighbouring York Road and Winstanley Estates in Battersea, which will see more than 2,000 new home built. A range of affordable homes will provided for people to buy or rent at below market rates and the number of social rent properties will increase.

HS2 cost jumps by £5.6bn

Group campaigning against HS2 have highlighted large disparities in figures predicted by HS2 officials and politicians and the actual financial cost to Britain.

George Osborne announced as part of the Autumn Statement that there would be a £20bn increase in transport infrastructure spending. However, what he didn’t mention is that over a quarter of this is accounted for by an 11% increase in the cost of building HS2. Paragraph 2.85 of the Autumn Statement states:

“Construction will begin on HS2 during the Parliament, and the Spending Review confirms a funding envelope of £55.7 billion in 2015 prices, which will deliver HS2 from London to Birmingham by 2026, and to Leeds and Manchester by 2033.”

Up until now, the official cost of the construction of HS2 has been stated as £42.6bn in 2011 prices, with a further £7.5bn added for the cost of trains, so £55.7bn represents an increase of £5.6bn, or 11%. This figure for the overall cost of the HS2 project is almost double the original estimate published in 2010.

Mr Osborne also said that along with HS2, the Great Western, Trans Pennine and Midland Mainline electrification projects can go ahead. As all of these projects have been beset with serious budget problems, it is likely that the increase in capital spend within the Department for Transport is simply to cover the cost over-runs which have been caused by chronic mismanagement.

Back in July the Trans Pennine and Midland Mainline projects were ‘paused’ by Government due to mismanagement and cost over-runs, only for them to be given the go-ahead in September. However, the costs of these projects is unclear. Just last week the Public Accounts Committee said it was “staggering and unacceptable” that current estimates for Great Western Electrification stand at £2.8bn, against a budget in 2013 of just £874m.

This news comes just a day after it was revealed that 46 members of staff at HS2 Ltd are paid more than the Prime Minister.

Stop HS2 Campaign Manager Joe Rukin responded “HS2 is abysmal value for money, and the increasingly dogmatic support for this white elephant and its’ spiralling costs is completely unfathomable. An 11% increase in the projected costs for construction is shameful after promises that the costs would be kept under control, but it is just another in a long line of HS2 cost hikes, and there will be more to come.”

“With trains not due to run for over another decade, who knows where the cost of this vanity project will end up and what else will have to be cut to pay for it? A responsible chancellor would be asking serious questions about whether HS2 is really worth it, not chucking more money at a boondoggle which would only benefit the richest in society. This is simply rewarding chronic mismanagement, and signalling that there is no need for budgetary control when it comes to HS2.”

Penny Gaines Chair of Stop HS2 added “HS2 is clearly a white elephant. Transport in the North does need improvement, but it isn’t the links to London which are holding back the economies of the North. It’s the ability to cross the Pennines, it’s getting into city centres from local towns. This is where the money needs spending on transport, not on one big showy railway line.”

“The government should make the decision to cancel HS2. There are far better uses for the money, which will have far better long and short term results. The people in charge of Network Rail when the now-delayed electrification programme was being developed are now in charge of HS2. They made a mess of that, and now they are making a mess of HS2.”

“Time and again, the government and HS2 Ltd have been overly optimistic about the cost of building HS2. It’s almost as if they picked a figure for the costs which was just about politically bearable, and then they hope no-one will notice when they increase it.”

Zedfactory to unveil groundbreaking solution to homes shortage at Ecobuild

, ,

Industry renowned architects and pioneers of the zero carbon agenda, Zedfactory, are set to unveil a groundbreaking solution to the housing shortage at Ecobuild. The solution claims to require no land whilst offering zero energy bills and the ability to relocate the property in the future, providing next generation future proofing.

The Government has pledged to build 400,000 homes over the life of this Parliament and there is currently little sign of that being delivered. In addition, as towns and cities expand, buildings are being demolished as a result of them no longer being suited to requirements. There needs to be an alternative visionary on how this will happen and Zedfactory believe they have found a solution.

Founded by Bill Dunster, OBE, Zedfactory are well-renowned as leaders in the field of zero-carbon design and development. Offering the full range of architectural services, from master-planning and design of large-scale ‘eco villages’ to one-off individual building commissions, the company has a unique track record of pioneering Zero (fossil) Energy Development (ZED) buildings in the UK.

ZEDfactory collaborates with the best global industrial partners to deliver replicable new construction industry solutions to assist timeless problems ranging from zero carbon urban design, architecture and product design in many climatic zones at a wide range of densities.

By looking at the way in which towns and cities grow and how the needs of their occupants change, coupled with unrivalled expertise in the creation of low energy buildings, Zedfactory have created a solution that could change the way the UK builds new homes.

ZEDliving – which will be exclusively unveiled at Ecobuild – is an affordable urban lifestyle solution that creates homes that require requiring no land, have no energy bills, no carbon footprint and help to reduce air pollution.

“If an affordable and low risk future powered by renewable energy is now possible, it is irresponsible not to provide it given accelerating climatic change,” commented Bill Dunster. “ZEDliving offers this. We are refining the zero carbon agenda and making it economically viable today by our homes being capable of having net zero annual energy bills. This offers a tangible benefit to everyone affected by rising fuel prices.”

“We are thrilled that Zedfactory have chosen Ecobuild to unveil ZEDliving, a unique solution to the delivery of future homes,” commented Martin Hurn Ecobuild Event Director. “Zedfactory has a reputation for delivering architecture that challenges and inspires. Their new solution looks set to continue this trend.”

Zedfactory will be exhibiting on stand number E4220. For further information about Ecobuild 2016 which takes place from 8th to 10th March at London’s ExCeL, please visit www.ecobuild.co.uk.
