  1. Renewable Heat Incentive turns up the heat for UK householders

    Leave a Comment

    Householders could get paid hundreds of pounds a year for heat generated by solar thermal panels, biomass boilers and heat pumps, Energy and Climate Change Minister Greg Barker confirmed today.

    The tariff levels have been set at 7.3p/kWh for air source heat pumps; 12.2p/kWh for biomass boilers; 18.8p/kWh for ground source heat pumps and at least 19.2 p/kWh for solar thermal.

    The new Renewable Heat Incentive (RHI) for householders is designed to drive forward uptake of renewable heat technologies in homes across Great Britain to cut carbon, help meet renewables targets and save money on bills. The scheme is a world first, and has been up and running for the non – domestic sector since November 2011.

    Today’s announcement follows extensive consultation on how a financial incentive would work best for householders and takes into account lessons learned from the Renewable Heat Premium Payment grant scheme (RHPP) and the RHI non domestic scheme.

  2. Solid wall properties can benefit from underfloor heating

    Leave a Comment

    Tŷ-Mawr Lime, a family firm based in Brecon, were the overall winner in the ‘Best Technical Innovation’ category of the South Wales Building Excellence awards, organised by LABC-Cymru (Local Authority Building Control – Wales), for their Sublime Breathable Flooring System.

    Sublime® floor’s breathability makes it ideal for use within existing solid wall properties.

    The sublime system is specifically designed for floors that will contain underfloor heating. Installing the underfloor heating pipes within a higher density thermally conductive layer eliminates the need for two layers (slab and a screed). As a result, the Sublime® floor offers many significant benefits and savings:

    Reduced overall excavation depths: When compared to a conventional Limecrete systems using a lightweight insulating slab layer plus a higher density screed layer to contain the underfloor heating.

    • Reduced wet trades and processes: As only one wet mixed layer is required over the GLAPOR.
    • Reduced installation costs: In both labour and in the cost of materials when compared to our old system
    • Reduced installation and curing times: By eliminating the need for two layers curing times are reduced by approximately 3 weeks
    • Improved energy efficiency and response times of under floor heating systems: As the insulation material is now directly beneath the heat source the heat drift associated with other systems is significantly reduced
    • Reduced material quantities and therefore reduced delivery costs
    • LABC Registered detail: (Received Feb 2013) Recognised in all 376 local authority areas, the registered detail will help to streamline and simplify the planning application and building control process for your project.

    This presentation will summarise a seven year collaboration between the University of Bath and Bristol based company ModCell Ltd in the development of prefabricated straw bale construction, focussing on two local projects: BaleHaus at the University of Bath and the Nucleus Building at Hayesfield School.

    Straw bale construction offers many potential benefits in the delivery of much needed lower carbon and more energy efficient buildings. The traditional use of straw bales on site, as large building blocks, has proven successful in self build and other smaller projects, but has failed to be accepted by mainstream construction industry. The use of straw bales in prefabricated (factory manufactured) building panels, both for cladding and load bearing walls, offers an innovative solution and that realises benefits and addresses many of the concerns.

    Pete Walker is the BRE Trust Professor and Director of the BRE Centre for Innovative Construction Materials and current Head of Civil Engineering at the University of Bath. His research interests include renewable materials (prefabricated straw bale; hemp-lime), modern earth building, lime mortared masonry and innovative timber engineering.



    Tim Mander has been at the forefront of sustainable design thinking for over twenty years and continues to pioneer some of the most exciting new ideas in the industry. As a Director of Integral Engineering Design, Tim is proactively involved in projects and provides a strong design lead. He firmly believes that good architecture and good engineering go hand in hand and need to be fully integrated to deliver high quality buildings cost effectively.

  4. High Court on the side of wind turbines

    Leave a Comment

    Judge Quashes Milton Keynes Wind Turbine Planning Document

    In what could be a landmark ruling on local planning policy about wind turbines, the High Court ruled in favour of  a challenge by RWE npower renewables to the Milton Keynes Supplementary Planning Document (SPD) on Wind Turbines.

    The High Court has ruled that the way in which Milton Keynes Council imposed fixed separation distances between turbines and dwellings was introduced incorrectly, breaching Regulation 8(3) of the Town and Country Planning Regulations 2012.

    Dr Wayne Cranstone, RWE npower renewables onshore development and projects director said: “On the matter of buffer zone policies more generally, the Judge concluded that National Guidance “plainly indicates” that local authorities should not have a policy that planning permission for a wind turbine should be refused if a minimum separation distance is not met… We welcome the clarity the Court has brought to this matter, and we believe this will help both the wind industry and local authorities in determining appropriate policies for the siting of commercial wind farms”

    Commenting on the ruling, RenewableUK’s Deputy Chief Executive Maf Smith said: “We welcome today’s decision as it provides the wind industry with the certainty it needs to get on with the job of generating more clean electricity for British homes.

    “Many local councils are aware of the benefits of wind energy – onshore wind is a growth industry for the UK, bringing much needed jobs and investment. Every megawatt of wind energy we install generates £700,000 worth of value for the UK, of which £100,000 stays in the local area. In real terms this equates to contracts for local businesses and jobs for local people.

    “Wind energy also offers us an escape route from costly imports of fossil fuels, by generating power from a home-grown resource which will never run out. This gives us a valuable prize: energy security. Onshore wind is the most cost-effective form of renewable energy we have, so we should be using it as widely as possible to protect all of us against soaring electricity bills.

    “RenewableUK strongly believes it’s inappropriate for councils to impose arbitrary limits on where renewable energy projects should be located. Blanket bans and buffer zones are blunt instruments which take no account of local conditions. Each proposal should be examined on a case by case basis so that a well-balanced decision can be reached. As two-thirds of the British public consistently support wind energy, their views should be given due weight in the democratic process”.

  5. Marshfield School wind turbine is back in business!

    Leave a Comment

    Marshfield School’s Proven P35-2 wind turbine, funded through PTA and other locally raised contributions as well as grants from EDF and LCBP, was recommissioned in January 2013. The school has already received a quarterly Feed in Tariff payment for energy generated, and is on track again to generate 50% of its annual electricity consumption.

    The wind turbine was commissioned in February 2011. In September that year Proven identified a technical problem and advised that the turbine should be stopped until it could be resolved under warranty. Unfortunately funder  support was withdrawn from Proven and the company went into receivership.

    Whilst the business of selling new turbines was sold to Kingspan, the warranties for existing turbines were not included in the sale.  A Scottish operator, with a large number of Proven turbines, developed a repair for their own machines and eventually gained MCS approval and capacity to offer the repair to other operators.

    The School joined the queue and the turbine was repaired and recommissioned in January 2013.

    The repair cost was generously funded by EDF after some prompting from our MP Steve Webb, and heavy lifting equipment was provided, at no cost, by M.J. Church.
