HBS New Energies completed the design and installation of 38 kWp solar PV system at Newington Butts, a 73-apartment new build development in South London. The scheme constructed by main contractor Allenbuild achieved Code for Sustainable Homes Level 4.

Allenbuild recently completed the construction of 2 Kennington Lane, a residential development in Lambeth, South London. The scheme owned by Dolphin Living, provides 73 new homes; 67 of which are affordable housing.

The six storey new build development includes retail space for a supermarket and cafe at ground level and a communal landscaped roof terrace for residents to enjoy the London skyline. HBS New Energies played a pivotal role in the projects success, delivering the solar PV requirements to ensure it achieved level 4 of the Code for Sustainable Homes.

Project delivery

  • HBS New Energies worked alongside Allenbuild to provide a specialist full service PV solution. We managed all stages of the project from design, supply and installation right through to testing and commissioning.
  • Following initial surveys, our in-house design and technical engineers worked in close consultation with the structural engineer to identify the flat roofs load capacity and required point loadings. This enabled HBS to calculate suitable ballast requirements and finalise a system design that would meet the client’s performance requirements.

  • The PV system was split between three sub arrays across three blocks. For each sub array an aluminium ballasted system was constructed and mounted onto a flat roof covered with shingle. This created a solid base for the system utilising concrete blocks.

  • The inclusion of solar panels proved to be the most cost-effective solution that would ensure the affordable housing scheme achieved its targeted level 4 of the Code for Sustainable Homes. 

  • Now commissioned and energised, the 37.96 kWp roof mounted solar PV system will provide a valuable on-site renewable energy source for residents, and will generate an estimated 33,211 kWh in zero carbon electricity per year.

  • Furthermore, the inclusion of solar panels will help to reduce the developments overall carbon emissions, delivering an estimated 17567.63 kg of CO2 savings per year.
