Edinburgh Home Demonstrator
Edinburgh
______ The Edinburgh Home Demonstrator is a new business model proposal for delivering affordable homes to net zero standards using offsite construction.
___________Introduction
Forming part of one of the UK’s most ambitious housing-led regeneration programmes in a generation, Granton Plot D1 for City of Edinburgh Council and developed and constructed by CCG (Scotland) Ltd, is the first site delivered under the council’s Edinburgh Home Demonstrator scheme, which is an applied research initiative that will seek to develop (and implement) a model for the design procurement, delivery of new affordable, net zero homes across the Edinburgh City Deal Region.
The innovative development will provide 75 new-build flatted dwellings and three ground floor commercial units.

___________Sustainability
The project is designed to comply with City of Edinburgh Council’s Housing Design Requirements, which requires optimised fabric, provision of low carbon heating and a high degree of onsite renewable energy generation. This approach achieves a carbon reduction of 80% allowing the project to achieve Aspect Gold Level 1 (Carbon Dioxide Emissions) and Aspect Gold Level 2 (Energy for Space Heating) compliance. The remaining 20% of carbon emissions from regulated energy will be offset by the local authority.
CCG’s iQ Timber System has been used to deliver an enhanced fabric performance using an offsite manufactured, closed panel timber system, providing a Modern Method of Construction (MMC). Heating and hot water are provided using an Air/Water Source Heat Pump communal heating system, which is connected to roof mounted solar photovoltaic (PV) panels, which provide electrical energy to power the heat pumps.
___________Our Scope
Carbon Futures have worked closely with our design team colleagues from the outset to meet City of Edinburgh Council’s ambitious design requirements. At design stage we undertook TM54 Operational Energy analysis to appraise the best method for connecting the PV panels to the dwellings.
This exercise looked at whether it was better to feed the PV panels to the individual flatted dwellings or to connect the PV arrays to the communal energy centre. As the energy centre provided the heating and hot water, it was found that connecting the PV to the energy centre maximised the utilisation of the renewable energy generated by the PV.
Additional consultancy services provided include Thermal Bridge Modelling, Approved Certifier of Design (Energy), SAP Calculations and Energy Performance Certificates.
