Dempsey Decourcy Architects

Ross on Wye

Derrie O'Sullivan Architects

Huddersfield

The Passivhaus approach to building design offers a tried and tested sustainable strategy which is meaningful because it is measurable in its use of energy and has no equal in our temperate climate. The methodology employs a combination of super insulation, appropriate areas of superbly designed triple glazed windows and doors for optimum beneficial solar gain, air tight construction with a heat recovery ventilation system ( MVHR) to achieve a space heating consumption of less than 15kWh/m2yr: which is vastly superior in comparison to the current UK Buildings Regulations which is in the order of 120kWh/m2yr. Passivhaus is the most cost effective way to save our finite energy resources and offers a high quality of thermal comfort for the people who use and live in the buildings.

Gresford Architects Ltd

London

Gresford Architects are based in London and Oxford and seek to create buildings that are thoughtful, practical, sustainable and beautiful. We are interested in how spaces (and the buildings that create them) make us feel; how every decision that goes into creating a space – the materiality (surfaces, joints, planes, textures), the positioning of the windows and doors, of lighting and heating – must be carefully considered to allow the perfect marriage of the poetic and the practical. We have a fundamental belief in the importance of building in a sustainable manner, so that the buildings we create last for generations, are efficient in their use of materials and energy (in both construction and use) and are comfortable and pleasant places to be. We have a Certified Passivhaus Designer among our staff and will soon be recognised as a Certified Passivhaus Designer as a practice. We believe that the Passive House Planning Package (PHPP) is a tool that should be used to help design and inform the creation of new buildings from the outset, and encourage our clients to see the long term benefits of the early adoption of PHPP modelling on their projects. We also work with a wide range of experienced Passivhaus consultants, contractors and subcontractors, and can thus help our clients put together the right team to deliver their projects.

MH Architects was formed as Miller Hughes Associates in 1986, rebranding as mh Architects in 2008. We are based in Chichester and work across the south of England. We strive to make architecture that can inspire both inside and out, marrying attractive appearance with straightforward functionality to give our clients buildings that will be enjoyed for years to come. We believe that good design is about achieving the objectives of our clients in the most elegant way possible, using the optimum resources available, in the most economical way. In our view sustainability should be truly integrated in all buildings from conception and the challenge for us is to fuse this with design that genuinely responds to its context and occupants.

Mike Whitfield Construction Ltd

Hereford

Mike Whitfield Construction Ltd is based in South Herefordshire. Mike first worked on a carefully designed energy efficient building in 1996, and since then has been on a steadily improving journey. In 2005 we were main contractors on the conversion of 2 barns into offices for the sustainable architects Architype, a project which won the 2007 RIBA Sustainability Award. By the time PH became known in the UK, we were already using many of the principles, and in 2010 when we started our first project that had been designed using PHPP, it was a natural progression for us. Since then we have worked almost exclusively on retrofits, extensions and new builds to PH principles. Mike has spoken on construction methods and detailing at AECB and UK Passivhaus conferences.
