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

Oxford

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.

Method Architecture

Edinburgh

Method Architecture is Edinburgh based practice with a focus on domestic architecture. Designing to Passivhaus standards is part of an ecological approach to architecture. As the most rigorous assessment of energy in use for buildings this is key tool to making buildings comfortable while reducing the environmental impacts of construction. In the context of a climate emergency, architecture could be defined as the responsible use of the world’s finite resources for the greatest benefit of society. Passivhaus brings some scientific rigour to a profession based in art, and gives a reliable metric for the energy performance of buildings.

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.

Tim Martel

Stroud

Tim is a freelance Chartered Architectural Technologist, Passivhaus Designer and Retrofit Co-ordinator. He is an expert in PHPP and is the author of the AECB PHribbon, an add-on to PHPP that speeds up data entry, checks PHPPs and calculates the Embodied CO2 of buildings. Embodied CO2 is becoming important as the grid decarbonises and heating gradually moves towards decarbonising. What is left is mostly the Embodied CO2 of the building. He offers calculations using the software and he also sells the software on behalf of the AECB (via his own website below). He offers advanced PHPPs that use ‘variants’, a very useful standard feature from the Passivhaus Institute, that allows you to explore different options in PHPP, e.g. different roof types, different wall types or different retrofit strategies. He has also created automated sensitivity testing in PHPPs, design studies which explore the effect of changing individual parameters and also the effect of combining them together.

WonKy: People Architecture Cities

London

WonKy is the partnership of Wai-Piu Wong and Lefkos Kyriacou (Certified Passivhaus Designer) with over 30 years collective experience in practice. The directors have taught extensively at universities and schools and been involved in architectural research and publications. WonKy considers the role of architecture and design in the context of broader societal issues to address problems and find opportunities to create projects that can deliver a significant impact. The practice undertakes research to inform and underpin their projects with an emphasis on the city and urban issues, with people first. The practice collaborates with artists, collectives, community groups and local authorities. WonKy places social and environmental sustainability at the core of the design process with a growing focus on urban ecologies.
