Integrating Water and Energy Efficiency in South Cambridgeshire

Integrating Water and Energy Efficiency in South Cambridgeshire

Cornerstone was awarded a four year contract to insulate South Cambridgeshire District Council’s housing stock in July 2016. To add value to this contract, we engaged the local water company, Cambridge Water, to help us to raise awareness of the importance of water efficiency, as well as energy efficiency, to householders.
Since Autumn 2016, we have been providing householders receiving insulation measures with a pack including a range of water efficiency measures such as shower timers, tap aerators and toilet leak detector strips. These measures are provided by Cambridge Water as part of their commitment to educate domestic customers and support them in reducing excess water usage. Over 30 households have benefitted from these packs to date.

The water efficiency measures will help householders to minimise the volume of water they use through day to day activities, which will in turn reduce their water bills if their properties are metered. In addition, the reduction in usage enhances the sustainable credentials of the scheme, with less waste water being passed through the carbon hungry treatment process.

Cornerstone’s Contracts Manager, Simon Walker, commented: ‘Cornerstone is delighted to have formed a partnership with Cambridge Water to reduce the utility bills of householders across the board. Householders have warmly welcomed the initiative, which we hope to roll out on a larger scale in 2017.’

Steve Colella, Senior Water Delivered Analyst at Cambridge Water, commented: ‘Cambridge Water is very happy to support this water and energy saving imitative and sees it as an effective and efficient way of helping our customers not only to save water but also reduce their energy and water service charges. One of the biggest benefits can be seen by reducing the energy used by reducing the amount of hot water, particularly either by reducing the time spent in the shower or installing an aerator or an aerated shower head. There are a number of very simple ways of reducing the amount of water and saving on utility bills. Simple devices that reduce the volume of older toilet cisterns and turning the sink tap off when cleaning teeth are simple measures that are promoted as part of this partnership with Cornerstone and South Cambridgeshire District Council. I would encourage all customers to explore this imitative and thank both South Cambridgeshire District Council and Cornerstone for their commitment and support’.

John Huntingdon Centre in Sawston, Cambridgeshire

John Huntingdon Centre in Sawston, Cambridgeshire

Cornerstone was engaged by main contractor C J Murfitt to install insulated render on the John Huntingdon Centre in Sawston, Cambridgeshire.
The centre is a vital community hub run by the John Huntingdon’s Charity, which provides practical support to disadvantaged and vulnerable persons within Sawston.

The project was worth approximately £25,000 and was completed to an exceptional standard over a period of two weeks in July 2016.

The building was largely of solid wall construction, with some areas of cavity wall. Cornerstone installed a PermaRock phenolic external wall insulation system incorporating 60mm phenolic boards with a reinforced mesh clothe render base coat and a 1.5mm ThermoSan-Fassadenputze NQG K finish.

External wall insulation was one of a number of elements of a full renovation project taking place at the centre, which was closed for the duration. Cornerstone worked closely with a variety of other contractors and tradespeople, ensuring our schedules and works integrated intelligently.

“I am very pleased with the standard of work delivered by Cornerstone, which has transformed the centre. I found Cornerstone to be a very knowledgeable, professional and responsive company that I would certainly use again for similar projects.” – Colin Sheldrick, Site Manager at C J Murfitt

Proposed Changes to ECO Funding

Proposed Changes to ECO Funding

DECC have recently published their consultation on proposed changes to ECO 2017-18 and a longer term supplier obligation:

The proposed changes are significant for local authorities and housing associations, and include:
1. There will be a greater focus on low income/fuel poor households.
The plan is to remove CSCO by April 2017 and reduce the CERO target, moving the reduction into the HHCRO obligation. The HHCRO qualifying criteria will in turn be simplified, increasing the number of households that qualify.
2. Social properties will qualify for HHCRO funding for the first time;
the local authority/housing association will sign a declaration to confirm they deem the tenant to be fuel poor, avoiding means testing. The funding will cover all social properties with an EPC rating of E, F and G.
3. The focus of HHCRO will shift away from heating and towards insulation
and particularly hard to treat measures including SWI, room in roof and park home insulation. An additional target of 17,000 solid wall properties are to be insulated by 31st March 2018.
4. There will be revisions to the Renewable Heat Incentive (RHI),
moving it away from the able to pay market and towards low income/fuel poor properties.
The impact of these proposed changes on funding rates and availability will be significant. It is important that local authorities and housing associations are prepared to take advantage of the changes as they come into force.

Cornerstone has agreements with a number of obligated parties, enabling us to access ECO at best market rates; we also work closely with organisations including the NEA. We are therefore well placed to advise on the development of a strategy to take advantage of future ECO funding, whether this be targeting social stock, owner occupiers or private landlords.

For more information or to talk to one of our funding experts, please telephone us on 01379 853 613 or click here to send us an enquiry.

We will be working in partnership with South Cambridgeshire District Council for the next 4 years

Alumasc & Cornerstone Help Lift Residents Out of Fuel Poverty

Alumasc & Cornerstone Help Lift Residents Out of Fuel Poverty

Posted by Jay Connolly on

An innovative scheme to install energy efficiency measures at a park home site in Elton, Cheshire is lifting vulnerable residents out of fuel poverty. The scheme is being managed by Cheshire West and Chester Council, part funded by National Energy Action. Approved installer Cornerstone have installed the Alumasc Swistherm EWI system improving thermal performance and providing an aesthetic transformation to the homes.

On average, park home residents are older and on lower incomes than the general population, and as a result, are more likely to be in fuel poverty. Due to technical challenges and a historical lack of funding, this is the first significant subsidised energy efficiency scheme in Cheshire West and Chester to target park homes.

Orchard Park is situated in a rural off-gas area within Cheshire and contains 109 privately owned park homes. All residents with non-insulated properties expressed interest in the scheme, with those living in the oldest park homes prioritised for works.

Site surveys and consultations with residents commenced in late 2015, with all measures on course to be completed by the end of April 2016. 48 propertiPark Homes EWI 2es will receive external wall insulation, with loft and underfloor insulation also installed where possible, along with heat recovery units fitted in 15 of the properties.

Monitoring of the thermal performance of the park homes before and after the installation of insulation and heat recovery units is being undertaken by National Energy Action. The installation of a range of product combinations will enable National Energy Action to make direct comparisons between the solutions, which will inform best practice in park home retrofit on a national basis.

All properties receiving insulation will feel considerably warmer. Residents will therefore use less energy in heating their homes, and will enjoy significant reductions in their fuel bills. The insulation will also refresh the external appearance of each park home.
