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.

Pen Y Coed Construction & Insulation

Welshpool

From Passive House design and construction to high quality joinery finishes, we pride ourselves in creating beautiful and sustainable buildings. With over 25 years' experience, we prioritise a 'Fabric First' approach that starts at the design stage, using materials and products that maximise the performance and energy efficiency of the building. Our timber frame houses begin life in our factory in Wales as fully engineered, insulated and air-tight closed panels. The panelised units are then transported to site where a weather protected structure can be assembled in a few days. The materials in our build systems are predominantly timber based and procured locally where possible. By using Warmcel cellulose fibre insulation along with timber and woodfibre lining boards, timber I-beams, timber windows, and timber cladding, carbon is locked-in to create a sustainable building that is healthy, comfortable and enjoyable to live in. Warmcel has also been awarded a Nature Plus Certificate. Full technical information is available on our website: pycgroup.co.uk and warmcel.co.uk.

Thermal Image UK

Strathaven

Thermal Image UK carries out air tightness tests and thermal imaging on new and old buildings looking for heat loss. The company was set up in 2008 by Tom Barbour and carries out surveys on a range of domestic and non-domestic buildings. Tom’s motivation is limiting climate change through better buildings, and he has been an advocate of improved building standards and quality control for a number of years. More recently, the realisation that Passivhaus not only sets a higher energy design standard but that you get built what was designed, has led to Tom becoming a strong advocate of Passivhaus.

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.
