Seven houses and two bungalows to Passivhaus Standard and Code level 4 were delivered under budget. Our aim was to deliver both sustainable and affordable housing for occupants. A fabric first approach was adopted for the design and construction inspired by the Passivhaus Standard and ensuring energy demands, fuel bills and maintenance are as low as possible. The fabric first approach also ensures that the energy performance of each dwelling will meet level 4 of the Code for Sustainable Homes without the need for bolt on renewable energy technologies. Three plots achieved Passivhaus certification.

There are no radiators or focal fire places within the homes. The only additional heating is from towel rails in the bathroom. A mechanical ventilation heat recovery system is used to provide heating, this highly efficient system recovers waste heat produced by items within the house (kettles etc). The homes have separate plant rooms for the mechanical kit with access only available through a separate external door. Our procurement teams researched and purchased specialist products with low u values including triple glazed windows and doors to ensure heat loss is minimised.

"Just wanted to say thank you to you all for 9x excellent units at Hart Lea! Very impressed not only with the end product, but especially with how you've worked on the project with us and with what has been achieved. Congratulations, looking forward to working with you all again." Matt Rice, Senior Development Officer, EMH Group.
