Passivhaus snowballing in the UK

The Passivhaus movement in the UK is gathering momentum with WARM’s new Passivhaus certification service today (Friday 30th April) certifying three diverse Passivhaus projects. A £1.4 million centre for disability studies in Essex, a £141K detached house in West Yorkshire and private detached house in Camden were all certified today as WARM’s first three certified Passivhaus projects, with the endorsement of the Passivhaus Institut in Germany.

WARM: Low Energy Building Practice is an independent consultancy, offering a wide range of low energy building services, including training, design, testing and certification. Founded by Peter Warm and Sally Johns, the practice has recently become a registered Passivhaus certifier, following an internship at the Passivhaus Institut in Germany.   Passivhaus is fast becoming the byword for quality buildings and year round internal comfort.

The projects certified today include:

Centre for Disability Studies, Rochford, Essex.

Designed by Simmonds Mills architects for Disability Essex, the £1.4 million project aimed to create accessible and cost-effective offices, training rooms and meeting space for the organisations’ staff and clients. Built using an externally insulated masonry frame, using AECB gold detailing, the building has projected annual heating bills of £300 (for a 550m2 building). The project received support from the East of England Development Agency and has been rated BREEAM Excellent.

CamdenPassivhaus, London

Designed by bere:architects, the timber frame [circa.120m2 ] two bedroom home has predicted annual heating bills of well under £100. This is achieved by 380mm of insulation, negative psi values throughout (no cold bridging), triple glazing, Passivhaus sliding windows, draught free construction, and 92% efficient heat recovery ventilation consuming only 15 watts of power in extract and supply. Summer temperatures are controlled by blinds, a well insulated structure, and two green roofs.

Denby Dale Passivhaus, West Yorkshire

Designed and built by Green Building Store’s construction division, Green Building Company, the Denby Dale Passivhaus is a [circa.120m2 ] three-bed detached house built for private clients for their retirement. Built for £141K, the project is the first cavity wall Passivhaus in the UK and has projected heating costs of again well less than £100 a year. Green Building Store’s Ecopassiv windows, heat recovery ventilation and airtightness products were used.

WARM is currently involved with a number of other projects working towards Passivhaus certification, including social housing schemes, large residential developments, schools, community centres and retrofit proposals.
