About us

The Green Register is an independent, self-funded and not-for-profit organisation whose principal goal is to promote sustainable building practices across all disciplines of the construction industry.

Launched in October 2000, The Green Register was initiated by Lucy Pedler’s architectural practice archipeleco, who wanted to create a network of like-minded construction professionals across the borough of Southwark, London. The Register was given start-up funding and support by Southwark Building Control and Sustainable Energy Action, and very rapidly expanded from a local list of architects and engineers to a nationwide network of construction professionals, tradespeople and supporting Local Authorities.

In October 2005 The Green Register became entirely self-supporting when the office moved from London to Bristol, and membership continues to grow. Lucy Pedler is Director of The Green Register; Birgit Nicklitzsch, Manager, runs The Green Register office and we are guided by our members through our steering group and Regional Coordinators.

The Green Register runs the two-day introductory ‘Sustainable Building and Services’ course at locations throughout the UK – this was the first course of its kind to launch in the UK. TGR also organises a wide range of seminars and training events and in-house CPD sessions on a variety of cutting-edge sustainable construction topics.

The Green Register can provide in-house CPD (Continuing Professional Development) sessions for a wide variety of small and large organisations, ranging from general overviews of sustainable construction topics through to specifically tailored sessions. Organisations we have provided CPD sessions to include entire RIBA regions, PRP Architects and a series of fourteen bespoke sessions for Stride Treglown offices around the country.

Our aims are achieved through our three core activities:

  • Training – raising awareness of the issues surrounding sustainable building practices by running training and events across the UK. These events range from half day practical workshops through to the full two-day Sustainable Building & Services training course. The Green Register also runs in-house CPD sessions for construction professionals on a wide range of topics.
  • The Register – all our members have attended a training session with The Green Register, once registered, are placed on the web-based register of members. This list is available to potential clients who are looking for professionals with a demonstrated commitment to sustainable building practices.
  • Networking – it is important to exchange ideas, provide mutual support and make professional connections with other disciplines – our events provide an ideal opportunity to meet other like-minded individuals and network, share ideas and information.

What is Sustainable or Green Building?
Building to green or sustainable principles is an holistic approach that addresses social, environmental and economic issues. It is not a style or fashion but an enduring set of principles that looks at all aspects of construction from site preparation through to reuse, recycling and reclamation. Sustainable building considers how the construction will affect the wellbeing of people and natural ecosystems.

We will adhere to the following principles in all our activities:

  • We will aim to be an ethical business in all respects. This includes:
    • Treating people with respect
    • Using public transport wherever possible
    • Using environmentally responsible suppliers
    • Choosing working partners who share our principles
    • Supporting like-minded charities and organisations when funds allow
  • We will organise regular educational and social events throughout the UK for our members and others, providing clear, impartial information on cutting edge issues.
  • We will ensure that all our members achieve a minimum standard by attending at least two days of Green Register training.
  • We will promote ourselves, our members and the principles of sustainable construction in everything we do.
  • We will be guided by our members through the steering group.

In 2004 the Green Register Steering Group was formed so that members could contribute to the ongoing activities of the organisation. This group is made up of Green Register staff members, some of our trainers, members who expressed an interest in being involved and representatives from our supporting Local Authorities.

The Steering Group is an invaluable resource for those of us that run The Green Register on a day-to-day basis. The group meets once a quarter; we advise the group on the activities of The Green Register, seek their input and advice on decisions we make and generally benefit from their guidance.

If you are a Green Register member and are interested in joining the Steering Group, please note that we meet 3-4 times per year and so you would be asked to donate your time once a quarter (meetings usually run from 1.30pm to 5.30pm and are held in London). Please contact us to find out if there are vacancies.

The Green Register Core Training Team

Lucy Pedler

Photo of Lucy PedlerLucy Pedler is an architect with 31 years of professional experience in the UK and USA and has particular expertise in sustainable building practices.

Lucy worked as a Product Specialist at Construction Resources, the UK’s first Ecological Building Centre, for five years. She spent the first two years researching the environmental impact of ecologically sound building materials and systems and the subsequent three years advising architects, other professionals and visitors on the appropriate selection of building materials. She was also responsible for running the seminar programme at Construction Resources and still makes regular presentations to architects and other organisations as part of The Green Register team.

In 1999, Lucy started her own sustainable architecture practice, archipeleco, designing buildings that have a low impact on the environment. In 2005, Paul McWilliams joined archipeleco to then create develeco limited, a company exclusively self-funded to offer refurbishments of existing buildings - usually in very poor condition - and transform the properties into sustainable, beautiful buildings fit for 21st century living.

Lucy created The Green Register in 2000 as part of her lifelong commitment to the promotion of sustainable building.

Lucy is co-chair of WESCON (West of England Sustainable Construction network) and on the panel of the Bristol Urban Design Forum.

Robert Borruso

Photo of Robert BorrusoRobert Borruso has studied to degree level both mechanical engineering and environmental science and has 10 years experience in both fields. This combination gives him an exceptional understanding of the issues associated with moving sustainable energy systems from the fringes to the mainstream of the construction industry, with a focus very much on delivering pragmatic and workable solutions.

Robert is currently working as an independent energy consultant with a client base ranging from small community groups to housing associations. He also has extensive experience in troubleshooting existing underperforming, renewable energy installations. He also occasionally writes on environmental issues in his own, often controversial, style.

Robert’s previous professional experience includes four years as a Product Specialist at Construction Resources Environmental Building Centre and as a Renewable Energy advisor at Sustainable Energy Action, both in London. He now lives in Scotland and is involved in a much more hands on approach with renewables.

Brian Murphy

Is a technician and architect by training, specification writer by choice and environmentalist by action. Brian Murphy’s last 40 years in the industry have been challenging and gratifying; greening up his act since 1999 these have been the most enjoyable. In 32 years of consultancy he specified large and small projects with a cumulative value of over £2415m. He founded National Green Specification (NGS) in 2001 to try to right the wrongs of many fellow architects and to challenge the establishment that maintains status quo.

Brian’s highlights are working with students and practicing architects to enable them to achieve the ideas in their heads; bringing extensive materials, construction know-how and an environmental focus to the design process and driving enthusiasm for competency in exhilarating solutions.

Brian reverts to Specification writing to the last dot and crossed tee in robust specifications that are not rushed over the weekend; he also gets pleasure from power over numbers in Excel spreadsheet Calculators including: WasteCost® lite Calculator & Whole Building Embodied/Sequestered Energy/Carbon.

Brian has an appetite for recording what he has learned so he does not have to remember it (there is only so much he can keep in all at the same time), so is passing on this knowledge of environmentally sound design and construction through the www.GreenBuildingEncyclopaedia.uk website and has developed specifications for: products & materials; waste minimisation/management of materials/packaging; reclaim for reuse/recycling, and over 1000 PowerPoint files on Environmentally Sustainable Construction, Specification and Professional Practice CPD seminars & Lectures, which are being added to and can be downloaded from www.GreenBuildingEncyclopaedia.uk/shop/

Brian has presented TGR SBS day two workshops about Designing out Waste, Greening Your Office and NGS and also sits on The Green Register’s Steering Group.

The Green Register Staff Team

Lucy Pedler | Director

Photo of Lucy Pedler

Lucy started both The Green Register (TGR) and her architectural practice in 2000 when her children were 3 and 5 - she attributes the creation of these two new companies to sleep deprivation at the time.

From a desk in her spare bedroom, TGR has grown to be what Lucy had hoped it would be - a successful nationwide organisation promoting sustainable building practices. Lucy has had the pleasure of working with some very committed people and The Green Register team are second to none.

Lucy uses her architectural experience to inform the activities of TGR - understanding what training construction professionals need has contributed to the success of the organisation.

When not working with the TGR team, Lucy runs her own small architectural development company, focussing on providing affordable, small-but-perfectly-designed eco houses for those struggling to get on the first rung of the housing ladder. Lucy also enjoys cycling, cooking and walking in the great outdoors.

Dan Weisselberg | Business Development

Photo of Dan

Dan joined The Green Register at the beginning of 2015. This followed five years of getting to know Lucy as a householder and TGR as a partner of Bristol Green Doors one of the UK's biggest green open home events which he founded in 2010. He supports our business development through strategic planning and overseeing marketing. Following careers in music marketing (Wet Wet Wet, Def Leppard, The Pogues etc - 1980s), teaching (Design and Technology in secondary schools - 1990s) and house-husbandry (2000s), Dan followed an MSc in Advanced Energy and Environmental Studies at UEL / CAT. Out of this he was inspired to retrofit a number of energy efficiency measures to his own home, which in turn interested so many neighbours and friends that setting up Bristol Green Doors was an obvious thing to do.

"Joining The Green Register is a great way of using my experience of encouraging the normalisation of retrofit to get more of the public aware of what The Green Register members offer".

When not coming up trying to engage more people in the greening of their homes, Dan: stands behind the cooker producing food for his family; sits on his bike enjoying the roads around Bristol; dances behind the decks when DJing; or is lying down on the sofa watching Game of Thrones, THFC or cricket highlights. He's also a proud dad of two lively secondary school kids and husband to his fab wife Anna.

Birgit Nicklitzsch | Events & Office Manager

Photo of Birgit

Birgit joined The Green Register in 2010 as Membership and Events Co-ordinator. After many years experience working in events planning and marketing within the legal sector, she left the corporate world with an aim to work for an organisation which pushes for ethical choices and sustainability above profit.

Various roles at a range of third sector organisations followed, along with some invaluable time spent travelling, before she had the chance to join The Green Register. It was a perfect fit. Not to mention that construction pros are a lot more easy-going than lawyers!

In 2014 Birgit had a break from The Green Register with the arrival of a beautiful baby girl. Now she escapes the chaos at home a few days a week by coming into the office. When not at work she is busy encouraging and marvelling at her daughter learning to talk, walk, or do just about anything really, and still tries to fit in some cycling, yoga and gardening whenever she has a chance.
