RaMPHaus (Rooftop and Modular Passivhaus)

Whilst there are several other similar deep retrofit schemes across the UK, RaMPHaus is unique in that both the new and the upgrade of the existing homes are to achieve zero carbon using the Energesprong standard – a widely recognised as a solution for the funding and delivery of deep retrofit at the scale. Dubbed ‘RaMPHaus’ for its inclusion of rooftop, modular and Passivhaus design, RaMPHaus is designed to achieve the Passivhaus EnerPHit standard to reduce home space heating demand of approximately 80% which, coupled with new renewable energy systems providing both electricity via PV panels on the roof and heating via Ground Source Heat Pumps (GSHP), ensures its Zero Carbon balance.  

The improved airtightness enables the use of MVHR (mechanical ventilation with heat recovery) which is co-located with the GSHP for improved air quality and reduced heat losses. The architectural quality and aesthetic appearance of the existing 1960s block is hugely improved with a non-combustible over-cladding system. Extending the building footprint with a further 5 homes increased the development housing supply and cross subsidised the provision of a new lift as well as improved the phasing of the project thus reducing the impact upon existing residents. 

Quote from Client: 

“ECD Architects quickly put together a capable multi-disciplinary team to understand the innovation required apply market-leading tools and technologies to meet the demanding Energiesprong brief. The team iterated the solution, carefully considering the interfaces between work packages to hit the performance targets and create a solution which would deliver industrialisable approaches to deliver scale at reduce cost.” – Jon Warren, Energiesprong UK
