Exeter City Council


Exeter City Council has championed the Passivhaus standard over the last 10 years delivering over 100 Passivhaus affordable homes across the city to date. The City Council is currently constructing the UK’s first certified leisure centre and Extra Care Home village with completion scheduled later in 2020. The City Council also has its own private development company, Exeter City Living Ltd which has a pipeline of Passivhaus developments many of which are open market homes. Exeter City Living’s approach to development encompasses a triple-bottom line business principle, ensuring all new developments are Passivhaus, healthy, climate resilient to 2080 and offer value for money. The Council has accumulated substantial knowledge and experience of Passivhaus over the last decade and has a dedicated team of Officers and consultants who can be utilized on a consultancy basis to assist other Local Authorities or private entities with their Passivhaus ambitions

Greenoak Housing Association


Greenoak is a small developing housing association working in Surrey and Sussex. Since 2000 we have addressed the linked themes of sustainability, design quality and construction performance through a quality-driven development process. Our central tenet is ˜liveability": simple, passive solutions that will minimise the risk of problems for tenants and achieve good building performance. Future-proofing is achieved by allowing for renewable energy systems to be retro-fitted. The latest scheme in West Sussex is designed to CSH level 4 and is the first scheme to use renewable energy: a solar hot water system.
