2050 Now! Achieving the standards for 2050, and the potential role for innovative heating solutions in thermally improved homes

The project will be improving four homes to different levels and exploring the performance of new heating solutions to achieve the optimum balance of energy performance vs. heating input for these different technologies. The three main innovative heating technologies in this project are Baxi's Ecogen domestic CHP (dCHP), Baxi's Ambiflo ASHP and Nuaire's Sunwarm (combined positive input ventilation, solar thermal heating and solar hot water). The dCHP units will be installed in relatively worse performing households and the ASHP units in well insulated houses to understand the level of performance needed from homes to create the right environment for these technologies to achieve significant carbon savings.

A2 Dominion- Northholt,

This typical semi-detatched property has poor orientation for exploiting solar gain and the residents will remain in their home during the works, making this a particularly hard to treat property. The rewards however are great, with approx 5.9 million semi detatched properties in England which could be treated similarly. We aim to deliver a highly cost effective and replicable solution, using innovative solutions such as the solar shed , blown underfloor insulation, cork external insulation and bio-foam loft insulation in a holistic design approach. The proposals have been detailed and specified with a strong emphasis on UK based expertise and technologies.

Planned occupancy : For the SAP and PHPP modelling an occupancy of 2.1 people has been assumed as per the TSB competition requirements. For the hot water assumptions for sizing the solar thermal system an occupancy of 3 people was assumed which we feel is a more realistic figure for a 3 bedroom house.

Addressing Energy Consumption and Climate Change Adaptation in non-South facing, post-Decent Homes properties.

The project property is an east-west facing, brick cavity construction, mid terrace house built in 1992. This type and era of dwelling correspond to approximately 100,000 similar social properties in England alone. We have developed a holistic strategy that will reduce the CO2 emissions of our proposed property by 80% whilst addressing how existing homes can adapt to climate change in the future. Our proposal is a combination of existing technologies used along side new innovative solutions to form a comprehensive strategy to reduce heating, hot water and electricity use. The underlying strategy is replicable across all terraced housing.

  • Whole house calculation method : SAP

  • Airtightness : 6.76 m³/m².hr @ 50 Pascals

Planned occupancy : The current tenants have lived at the property for nearly 17 years. The presence of a long term, sitting tenant will help the team to collect valuable operating energy use data and demonstrate the impact of our behavioural change measures. It is proposed that the tenants will remain throughout phase 2. Close communication and considerate construction practices will help to avoid decanting the residents. We believe this is important to enhance the scalability of our proposals.

Admirals Hard

FINALIST of the UK Passivhaus Awards 2015 - Situated on the Stonehouse peninsula, by the banks of the River Tamar, Number 3 Admirals Hard was built in the 1950s and comprises a shop on the ground floor and WARMs office, originally a flat, on the first floor. The first floor is EnerPHit certified. The extensive retrofit works included external wall insulation, cavity wall fill, floor insulation (between the office and the shop), roof insulation at rafter level, high levels of air tightness and high-performance triple-glazed windows, as well as a self-balancing MVHR system.

Almshouses, Cambridge

This project will focus on a mid-terrace, 1-bed almshouse property in Cambridge. Our approach to energy saving and CO2 reduction is to follow a lean-clean-green hierarchy: seeking to minimise heat losses from the property thermal fabric and ventilation method; to supply residual space and water heating using replicable, low carbon technology; to minimise lighting and appliance energy loads; and finally to consider micro-generation using proven, renewable energy systems.
