SolarTech Ltd, one the UK’s leading renewable energy specialists, has designed and installed an innovative new photovoltaic (PV) carport system for Waltham Forest Council, thought to be one of the first of its kind to be used to generate electricity by a Borough Council.
The bespoke system of mono and dual wing cantilever solar carports was specially designed for the Council staff car park adjacent to Juniper House in Walthamstow, as there was insufficient space to accommodate a conventional PV system on the roof of the building.
Not only do the solar carports provide cover for 17 vehicles, without any reduction of the existing car parking space, but the 27kWp PV arrays can also generate approximately 21,600 kWh worth of solar energy per year. This can be used to provide free electricity for the Council office buildings, whilst generating a significant income from the Government’s “Feed-in tariff” scheme that pays an enhanced rate for this electricity (even if it is used by the Council).
There is also the option of integrated electric car chargers, which could help encourage the use of electric vehicles in the future.
As principal contractor, SolarTech was responsible for the delivery of the bespoke designs, including structural calculations and planning applications, through to fabrication, supply and installation of the arrays, all of which were completed within a limited five week time frame. The company is also providing a maintenance contract.
“This is a highly innovative and cost effective solution, which has made the most of our available space to produce renewable energy on-site, whilst helping reduce CO2 emissions, and demonstrating the Council’s ongoing commitment to a greener future through investment in renewable technologies,” said Trevor Brown, Project Coordinator for Waltham Forest Council.
SolarTech has also delivered a number of conventional solar PV arrays for the rooftops of the surrounding civic buildings in support of the Council’s ongoing strategy to provide energy from renewable sources across the Borough.
“Our ‘Sola-Port’ solar car ports are an excellent investment for local Councils, or anywhere that offers extensive car parking facilities, as they supply free solar electricity, as well as earning additional income from the Government’s feed in tariff scheme, which can then be reinvested into projects for the benefit of the community,” said Shaun Taylor, managing director of SolarTech.
SolarTech has extensive experience of working with both public and private sector organisations. The company offers a wide choice of renewable technology solutions from photovoltaic (PV) electricity, including solar car port options, solar hot water, through to biomass, ground and air source heat pumps and wind power, which can be fully integrated and tailored to meet the specific needs of clients and individual projects.

Following the rapid adoption of Insulslab SFRC by a series of national housebuilders, an Approved Installer Network has been launched that will provide access to a team of fully trained, highly efficient and extremely competitive ground engineers who are qualified to work with the Insulslab system.
Insulslab SFRC is a fully integrated and super insulated foundation system that has been proven to deliver time and cost savings on-site whilst achieving superior levels of thermal insulation. Constructed of interlocking expanded polystyrene (EPS) pods, Insulslab SFRC is simply laid in place to form a rigid waffle shaped slab, with steel fibre reinforced concrete (SFRC) then poured on top to deliver the foundation up to ground floor slab level.
Since its UK launch, BBA-approved Insulslab SFRC has grown in popularity with developers as it significantly increases speed of build, supports the thermal performance of buildings and has significant savings over traditional, deep trench and pile foundations. In response to this demand, Insulslab SFRC has developed the national Approved Network to further increase the efficiency of build for developers.
Andrew Orriss, Insulslab SFRC, explains: “Whilst an Insulslab SFRC technical engineer attends the start of all new developments where the system is used, we recognised that by having a pre-approved network of ground engineers nationwide, we will remove the vulnerability of on-site training at the start of each project. Instead, there will now be fully trained ground engineers able to hit the ground running.”
As a new programme, the Insulslab SFRC Approved Network represents an opportunity for established ground engineers to diversify their service offering and achieve competitive advantage. As a fast-track method of construction which supports sustainable insulation targets, Insulslab SFRC is set to triple in volume in the next three years.
Andrew Orriss continues: “Ground engineers who achieve accreditation early on will be at a distinct advantage over those that continue to only offer traditional groundwork services. Becoming an Approved Insulslab SFRC Installer will essentially set them apart from the competition and potentially open up new routes to work with some of the UK’s major housebuilders.”
To achieve Approval, ground engineers will need to undertake a comprehensive induction with Insulslab and SFRC manufacturer, Arcelormittal. Following on from this theory based workshop, a series of on-site inspections must be completed with Approval reviewed annually. As a nationwide network, Insulslab SFRC will provide approved ground engineers with opportunities to tender for local Insulslab SFRC projects direct with the developer or main contractor.
Lincolnshire-based renewable energy products distributor Eco Building Products has replaced the traditional florescent lighting at its Market Deeping premises with a new sustainable system from Envirolighting Ltd and has been so impressed with the results it has signed a deal with the supplier.
Sister companies Lark Energy and Kestrel Timber Frame also had new lighting installed. All three companies, part of the Larkfleet Group, have seen real savings in energy and costs since installing new tubes and switches.
Eco Building Products is a leading supplier of alternative energy technologies, insulation materials and other products aimed at making new and existing buildings ‘greener’.
Ian Greenfield, operations director at Eco Building Products, said: “The Envirolighting installation cost around £3,000. We are already seeing energy savings of up to 80 per cent and expect payback in less than two years.
“There were no new fittings, just tubes and starters, which keeps costs and installation time to a minimum. We have also installed eco light switches that only turn on some of the lights in a room. If it is too dark, simply flick the switch again and all the lights will come on. As a result, some rooms are using half the number of tubes all the time now, giving us a real saving.”
As a result of the savings that it has made, Eco Building Products is now working with Envirolighting to offer free lighting surveys to its customers and to promote Envirolighting lighting solutions for commercial premises.
Envirolighting contracts manager Paul Fowler said: “We are delighted that Eco Building Products is promoting our lighting solutions. Our surveys include an assessment of current lighting and light levels. We assess contributions of natural daylight to determine if this free light source can be used in conjunction with artificial lighting to maximise energy savings.
“Based on this we generate a proposal, which includes which lighting products we would recommend for each area of the premises, and a full energy report comparing current lighting to proposed. We highlight cost savings and reductions in energy consumption, increases in profit as a result and reductions in the business’ carbon footprint.
“We also often recommend a short trial period where we fit a small quantity of our recommended lighting products in a test area and run them for a brief time so that we can calculate average savings for the entire site. This allows customers to see the benefits of our recommendations without committing to a full project implementation.”
Envirolighting’s solution includes the installation of retrofit fluorescent T5 adaptors which are more efficient than old-style T8 and T12 fluorescents. These T5 adaptors provide the necessary high-frequency ballast to adapt switch start and starterless fittings to accept energy saving T5 fluorescents tubes with simple plug-and-play speed. This energy-saving lighting solution means an easy change to efficient lighting without the need to replace the light fittings or cause disruption.
In addition to the T5 retrofit adaptors, Envirolighting solutions also include sensor control and efficient HID dimming where fittings can be dimmed to ten per cent of their normal output when areas are unoccupied. As the fitting automatically turns back up to full output again when presence is detected, ‘re-strike’ times no longer become an issue.
Ian Greenfield added: “We have joined forces with Envirolighting to further enhance our ability to supply the best in renewable energy products to our customers.
“Eco Building Products is committed to providing the best range of quality renewable energy products available to the trade in this region. Our partnership with Envirolighting will help us to achieve that.”

The energy management and natural ventilation systems for two innovative carbon-neutral homes in Kettering, Northamptonshire, UK have been supplied by WindowMaster (www.windowmaster.com).
The two semi-detached VELUX Carbon Light Homes (www.velux.co.uk) have been constructed to demonstrate that state-of-the-art energy-efficient sustainable housing is practical, affordable, appealing to home buyers and can be easily constructed by volume house builders.
As one of the integral partners in the project, WindowMaster installed its NV Comfort™ control system. NV Comfort™ enables an optimal indoor climate through consistent pure natural ventilation. At the same time it can save enough energy to significantly reduce CO2 emissions.
WindowMaster’s Paul Collins explained: “Carbon Light Homes are designed to be low energy buildings. The WindowMaster system is at the heart of the building’s management. It allows air temperature and quality in the house to be maintained with minimal energy expenditure. It automatically opens and closes windows in response to internal and external temperature, CO2 levels and weather conditions.
“The energy management system also controls the blinds so that they close to keep sun out in the warmer months to aid cooling and open in the winter months in order to take advantage of passive thermal gain.
“Energy management helps to heat the property by reducing the load on the other heating systems. Demand for fossil fuel energy for heating, hot water and electricity is kept to a minimum, making these experimental homes almost carbon neutral.”
The homes also use solar heating in combination with air-to-water heat pumps for hot water and space heating. Natural ventilation cools the buildings by taking advantage of triple height atriums around the stairs which create stack and cross ventilation. In hotter months, the homes are cooled using purge ventilation while internal and external screening helps to control solar gain and create a comfortable indoor climate. In winter, natural ventilation works alongside a mechanical ventilation system with heat recovery which recycles heat from the kitchen and bathrooms into the living areas. All of this is managed by NV Comfort™.
NV Comfort™ is based on WindowMaster’s established NV Advance™ system for management of natural ventilation in larger projects, such as schools and offices. Like the NV Advance™ control system NV Comfort™ regulates and adjusts internal air quality using an intelligent, computer-controlled system that harnesses the natural forces created by temperature differences outside and inside the building and by the effect of wind around the building.
NV Comfort™ controls façade and roof windows so that they automatically open and close by incremental amounts on the basis of individual fixed values for the desired room temperature and CO2 levels, as well as measurements of external temperature, rain and wind speed. The system also opens and closes blinds taking its cue from thermal mass readings from a pyrometer.
Opening of the automated windows can be overridden by the user to maintain security. Setting the desired room temperature and CO2 levels can be done individually for each room from one central location in the building via the NV Comfort™ touch screen.
Kier Property has been selected by the Health Campus Partnership (Watford Borough Council, West Hertfordshire Hospitals NHS Trust and Watford Football Club) as the preferred bidder to deliver the £240m Watford Health Campus project.
The company beat rival bidder Laing to be awarded the contract to deliver the 375,000sq ft mixed-use development, which will include new hospital facilities for Watford and south-west Hertfordshire, up to 650 homes and a new multi-storey car park.
The Health Campus will regenerate derelict land in west Watford and deliver new employment space and 1,600 local jobs. It will also allow better access for all to improved open public space and reduce traffic congestion.
Kier Property scored highly across a range of areas that ultimately saw its bid come out on top. The Health Campus partnership was particularly impressed by Kier as:
-its masterplan fully meets the aims for the scheme in terms of creating an attractive and sustainable community in west Watford that incorporates health, employment, quality open space and new homes
-its proposal keeps the hospital’s vision for new health facilities at the heart of the scheme and offers the flexibility needed to ensure this can happen
-it offers excellent value for money with a 50:50 long-term joint venture for the public sector
-it has a good track record of delivery and will appoint an experienced and skilled team to take its proposals forward
Nigel Turner, Kier Property’s MD, added: “We are extremely pleased to be selected as the preferred partner to deliver the Watford Health Campus scheme. We have worked closely with the Health Campus partners to understand their vision and aspirations for the Health Campus and the area overall. We believe our proposal will deliver the transformation that the partnership is looking for and we are now very excited to get started.
“We are looking forward to getting out and about in Watford to share our proposals with the local community. Our joint objective is to deliver realistic and achievable regeneration within a clear timescale.”
Commenting, Dorothy Thornhill MBE, Elected Mayor of Watford, said: “This announcement marks a significant step forward for the Health Campus and brings us closer to seeing our aspirations for the area finally come to fruition. The Health Campus is a once in a lifetime opportunity. It will deliver significant benefits to the town and gives a huge boost to our local economy at a time when other areas of the country are seeing reductions to public investment and services. There is still a lot to be done but I am delighted at the prospect of working with Kier on its exciting proposals and getting the best possible results for Watford and our residents.”
Jan Filochowski, chief executive of West Hertfordshire Hospitals NHS Trust, said: “We have been working hard to fulfil our vision for a modern general hospital for Watford and the whole of west Hertfordshire, so I am delighted that we have reached this important milestone in the Watford Health Campus project.
“The land around the hospital and the slope of the site has been challenging when trying to piece together the Health Campus ‘jigsaw’. The scheme allows parts of the hospital to ‘decant’, whilst other parts are built. It will transform the hospital facilities and site, creating green open spaces, tranquil water frontage and welcoming public spaces. Emergency and normal access to the site will be dramatically improved. At the end of the works our patients, staff and the local community are set to have fantastic new and improved facilities.”
Kier will also be working with the Health Campus partnership to complete the financial and legal aspects of their agreement by December.
Iron technology leader Saint-Gobain PAM UK, part of leading materials company Saint-Gobain, has released its latest sustainability report, demonstrating the successful steps it has taken to maintaining a commitment to sustainable development.
Saint-Gobain PAM UK’s third Sustainability Report outlines its environmental policy for achieving key sustainable targets, alongside setting future objectives for reducing carbon emissions, energy usage and landfill waste.
Paul Minchin of Saint-Gobain PAM UK commented: “Our products manufactured in the UK are made from 97 per cent recycled materials. As a leading manufacturer of ductile iron pipe systems, access covers and gratings, above and below ground cast iron drainage systems and fittings, we have an inherent advantage in meeting significant sustainability targets. Nevertheless, we strive to continuously meet ethical and economic goals, and our third Sustainability Report looks forward to the coming years and what we can do to further improve the environmental impact of our operations.
“Some of the most significant improvements in waste management can be seen at our sites in Holwell and Telford. At the Holwell plant, we have reduced waste being sent to our on-site landfill by 83 per cent in 2011. This was achieved through a range of initiatives, such as introducing reusable refractory ladle linings and selling used sand for building block manufacture. Our Telford site has also dramatically reduced its waste. In 2009, 3,200 tonnes of waste were sent to landfill at Telford, whereas 2011 saw this cut to 848 tonnes.
“A significant project has been on the Holwell Cupola furnace– the largest in the UK – which has really helped reduce our environmental impact at a local level. We replaced a wet scrubber system with a new control system, delivering a new dry bag filter solution, helping to meet stringent environmental targets for emissions reduction in particular. A heat exchanger was also fitted to recover waste heat from combustion gases. These steps have dramatically reduced water usage, electricity, raw materials and refractories to landfill. This investment was also a key factor in obtaining CEMARS – Certified Emissions Measurement and Reduction Scheme – accreditation, recognition we are particularly pleased to receive, highlighting our recent environmental efforts.
“Other notable achievements include a 4.3 per cent reduction in carbon emissions between 2010 and 2011, with a target of 7 per cent by 2014, plus a significant reduction in water usage of 18 per cent since 2009 across the company. In fact, the Cupola project at our Holwell site has cut water usage by 28,000m3 – a reduction of 63 per cent at that site alone.”
Peterborough-based Metrix Marketing (www.metrixmarketing.co.uk) and t2 Studios (www.t2studios.net) are working together to promote the sale of self-build housing plots at Hampton.
Hampton, the 7,000 home township being built south of Peterborough, has been growing at the rate of nearly 500 houses per year with around 20 building companies active on the site.
However, O&H Hampton – the company which owns the land and is managing the development – also has a small number of plots available for sale to people who want to build their own homes.
Roger Tallowin, general manager at O&H Hampton, said: “We have a long-term vision of a thriving, sustainable community. We see self-build homes as an integral part of that community.”
The company recognised that selling individual plots to would-be self-builders was going to be very different to selling relatively large sites to house building companies. So it called in Metrix Marketing to advise on a marketing communications programme to attract new potential purchasers.
Metrix recommended an internet-based campaign because more than 100,000 people in the UK search online each year for available plots to self-build. Metrix introduced t2 Studios, an integrated design and media agency with which it has a close working relationship.
Between them, the two companies created a new website – www.ohland.co.uk – which provides details of the self-build plots on offer at Hampton as well as helpful facts, figures and advice on how to build your own dream home.
Metrix also assisted with media publicity, including a large feature in Self Build & Design magazine, and other promotional activity including advertising designed by t2 Studios.
Roger Tallowin said: “Metrix Marketing and t2 Studios have helped us to raise our profile in a very difficult and competitive market.”
The self-build plots on offer are in Winsor Crescent in Hampton Vale West. They overlook a nature reserve on the northern edge of the Hampton community and have impressive views of a peaceful countryside landscape from almost every angle.
The group of 13 plots all have key services – provided by O&H Hampton – including foul and service water drainage, and utility connections for drinking water, gas, electricity and telecommunications. Each plot has a gated private driveway and a waste bin and utilities store are also supplied.
Five of the 13 plots have now been sold.
For information about the availability of plots in Winsor Crescent, visit www.ohland.co.uk or call O&H Hampton on 01733 293220.

Sheehan’s opens new construction & demolition recycling plant plus holds open days : 11th to Friday 14th September 2012
Oxford based Sheehan Haulage & Plant Hire, in conjunction with CDE Global, is holding a series of open days from the 11th to 14th September 2012, to showcase its newly commissioned construction & demolition waste recycling plant.
With sustainability and recycling high on the agenda of Government and Local Authorities across the UK, Oxford based public works and civil engineering contractors, Sheehan Haulage & Plant Hire, recently installed a new construction & demolition waste recycling plant.
The new multi-million pound facility, which was more than five years in the planning, was manufactured, installed and commissioned in June 2012 by CDE Global, the world leading supplier of washing equipment for quarries and mines, at Sheehan’s 150 hectare ‘Dix Pit’ recycling site on the outskirts of Stanton Harcourt in Oxfordshire.
As a result of the investment, 100,000 tonnes per year of construction & demolition waste from Oxford and the surrounding areas will be diverted from landfill and turned into high value construction aggregates, recycled sands and sub soil. The facility will be used to process construction, demolition and excavation waste from Sheehan’s own projects with additional waste being accepted from as far afield as Greater London. The output is turned into re-useable materials for future construction projects – 50% of which Sheehan’s currently uses on its own projects.
The new CDE Global waste recycling plant is able to process general building rubble, excavation and demolition material into a range of clean aggregates and shingles. These include 3.3mm, 6mm, 10mm, and 40mm grades, which primarily can be used for pipe bedding, with ranges of washed general building sand, fine grade soil and vibro piling material also being produced. In addition, the plant is able to remove other erroneous matter, including wood, plastics and metals which are then sent on for further recycling, while extracted water is reused and re-cycled as part of the washing process.
“Sheehan’s is striving to be better environmental stewards, and we endeavour to sustain natural resources wherever possible,” states Tara Sheehan, Financial Director of Sheehan Haulage & Plant Hire. “By processing all of our own construction & demolition waste and increasing the volume of local third party waste, we are already able to produce and supply recycled sand and sustainable aggregates to many local companies, in addition to meeting much of our own requirements for construction materials in the region.”
The construction & demolition waste is initially loaded into a feed hopper of the CDE Global solution and ferrous material is removed by an overband magnet and pre-screened to remove other erroneous material. Following an initial rinsing through an Aggmax™ unit to liberate sand particles, these are then sent to an Evowash™ unit for the first washing phase. Larger pre-screened material is then sent to the Rotomax™ logwasher for scrubbing and material is discharged to a dewatering screen, with further liberated sand particles recovered for final aggregate rinsing.
The screened and washed aggregate is then discharged to the triple deck Prograde™ that grades aggregates into 5-10mm / 10-20mm / 20-40mm / +40mm material. Waste water is re-cycled and filtered through the Aquacycle™ thickener with silt particles being removed and the waste sludge sent to a concrete buffer tank. Further filtering that creates a filter cake of approximately 90% dry solids content and all residual water is recycled back to the washing plant.
