We recognise the critical role of human behaviour in determining the real-life efficiency of buildings. For this retro-fit proposal, our aim is to influence the behaviour of the occupants by providing them with specific information on how the building is performing, and energy / carbon saving advice based upon detailed analysis of their actual usage patterns. We believe that we can demonstrate an effective and scaleable whole-house solution that can be cost-effectively and rapidly deployed by RSLs. The main elements of our proposal are: * Physical building upgrade with minimal tenant disruption * Real-time data capture and analysis * Communication with occupants * Wider Incentives and Issues

Design strategies

Planned occupancyDesign occupancy level is as current: one adult and one child
Space heating strategyAir source heat pump to wet radiator system.
Water heating strategySolar thermal with immersion boost.
Fuel strategyContinue reliance on electricity, with conservation and use of solar thermal and ASHP to reduce load.
Renewable energy strategyPV and other renewable generation strategies evaluated, but cost effectiveness considered too poor for widescale rollout .
Passive Solar strategyContinued reliance on solar gain from large windows to habitable rooms - no special measures for control or utilisation due to high thermal mass of structure (no internal insulation).
Space cooling strategyNatural ventilation and ad hoc shading.
Daylighting strategyContinued reliance on daylighting from large windows to habitable rooms.
Ventilation strategyControlled ventilation to be incorporated in replacement window units.
Airtightness strategy Improvement through replacement of windows and elimination or caulking of service entry points.
Strategy for minimising thermal bridges Additional loft insulation, carefully installed to cover gaps in existing insulation; and perimeter insulation to edge of ground floor slab. The scheme does not envisage additional wall insulation, so it is inevitable that thermal bridges will remain.
Modelling strategyDEMScot whole-house model, based on SAP 9.82 and BREDEM.
Insulation strategyAdditional insulation to loft, flat roof and slab perimter as described above.
Other relevant retrofit strategiesCarnego smart control system and strategies to influence user behaviour.
