This project used airtightness tests to identify sources of uncontrolled ventilation and cold spots in poor energy efficiency (SAP bands D G) properties in a rural area of Wales, highly exposed to sea winds, often solid walled or other hard to treat (HTT) construction, and most not being served by mains gas. Results of the tests highlighted appropriate airtightness measures which could be installed to address and reduce uncontrolled air exchange, to provide energy savings and improved comfort to the residents, vulnerable to fuel poverty.

No fines concrete houses are houses that have walls constructed from in situ cast concrete that does not contain the fine aggregate that is usually mixed within the concrete. This means that the larger aggregate (gravel of 10 20mm in size) is bound by a cement slurry coating. As such, connected voids are found throughout the walls. The result of this is that these house types do not behave like other solid wall properties in relation to heat retention, air tightness and resistance to moisture

The Health and Innovation Programme was a £26.2 million programme to bring affordable warmth to fuel poor and vulnerable households in England, Scotland and Wales. The programme launched in April 2015 and has delivered energy efficiency advice and measures to over 9000 households.

The project comprises the replacement of the heating and hot water systems of two residential sheltered blocks whose residents are over 55 years of age. The main block comprises 41 flats; the second and smaller block to the rear of the main block comprises 15 flats.

Ongo Homes installed three different types of innovative full heating systems into 30 properties from their social housing stock. Existing heating was removed and replaced with one of the three technologies: 14 Logicor infrared radiator systems, 10 Daikin Altherma hybrid heat pumps and six Sunamp heat batteries.

External wall insulation (EWI) is an established technology that improves heat retention and energy efficiency. In essence, EWI provides an external jacket to a park home that significantly enhances thermal efficiency. This should improve performance of existing building fabric, ensuring a warmer living space in winter months, and cooler living space in the summer months. A further stated benefit of EWI is improved sound proofing, which can further enhance the living experience of householders.

Research released by NEA has demonstrated that smart meters can benefit vulnerable and low-income households – but in most cases this requires additional support and advice.

This project was delivered by YES Energy Solutions in collaboration with North Lincolnshire Council.
