Real-life Retrofit: Case studies – 2. Comfort Catapult: Retrofitting a 200-year-old semi to modern building performance standards – Online

 Registration is closed for this event
The second in our series of three events looking at challenges and solutions within different retrofit case studies

 

Real-life Retrofit: Case studies

The built environment is a major contributor to the environmental pressures our world is facing. Rather than demolishing existing buildings, retrofitting of existing buildings can play a crucial part in meeting net-zero carbon targets. Retrofit involves modifications to existing buildings that will improve energy efficiency or decrease energy demand.

In this online event series we have documented three different retrofit case studies in the Bristol area, each building with a unique history and retrofit plan. Working with contractors trained under our Futureproof programme, we focus upon retrofit in real life to show the challenges and solutions in upgrading the performance of older buildings.

Session #2: Comfort Catapult: Retrofitting a 200-year-old semi to modern building performance standards

When a damp bathroom raised the alarm for client Jayne, she contacted Futureproof in Bristol for help and found contractors ECO-DC. From there a retrofit plan for Jayne’s 200-year-old semi-detached home in Bristol started to form to include upgrades in airtightness, insulation and ventilation.

EWI, roof insulation, breathable lime plaster, a DCV ventilation system, triple glazing and a consistent approach to airtightness throughout the property have all contributed to an energy-efficient and comfortable home for Jayne and her family.

Learn more with us as we invite the contractor, his client, the architect and the air leakage specialist to tell us about the project:

  • Mike Neate of Eco-DC brings passion and a wealth of experience in low-carbon building, Passivhaus and EnerPHit as the main contractor on this project. He'll discuss the realities of retrofitting historic buildings such as this home and the creative approaches taken to counter some of the issues that arose during the project. 
  • Julia Bennett is an architect specialising in low carbon building, natural materials, building physics, retrofit and Passivhaus. She'll outline the methodologies, challenges and solutions in bringing the home up to modern building performance standards. 
  • Paul Jennings of Aldas, an Air Leakage Specialist who worked on the project, will be explaining the airtightness and comfort improvements made and how these were measured using specialist techniques and equipment.

Each event can be attended as a stand alone session, or if attending the whole series they will complement each other.

What did our delegates say about the first event in the series?

"Real and relatable... there is so much talk about sustainability - it is really refreshing to see real examples. It is too easy to just say 'we need to insulate our homes' however it is not easy to do so I was interested to see how they did it."

"Excellent and frank insight from the design and construction teams"

"Very informative on assessments, detailing and products. Nice to see it from different perspectives, ie architect, SE and builder."

"A fantastic case study!"

In 2022 she will be extending her passion for training and building skills by working to develop new areas of technical training events with The Green Register.

 

Paul Jennings

Paul Jennings of Aldas is the most experienced airtightness tester and consultant in the UK, with over 30 years’ experience. He has presented at numerous AECB and Passivhaus conferences in the UK and overseas.  Paul has been involved in most UK PassivHaus projects to date in one or more capacities.

These schemes include:

  • the first UK certified domestic and non-domestic PH projects in Machynlleth, both built by John Williamson, initially tested in 2008 and then retested after a decade of operation in 2018
  • the Erneley Close (Manchester), Wilmcote House (Portsmouth) and Carlton Chapel House (North London) EnerPHit block refurbishment projects
  • the Agar Grove area regeneration scheme in Camden, where neglected 60’s social housing will ultimately be replaced by over 500 newbuild PH units
  • the Exeter Passivhaus swimming pool and leisure centre, currently nearing completion
  • numerous individual newbuild custom- and self-build Passivhaus schemes

Paul is an experienced trainer and originated the “Airtightness Champion” concept, as well delivering numerous on-site trainings and many CPD seminars to architects and builders. He developed the 12 Steps to Airtightness approach to enable UK contractors to reliably deliver airtightness in Passivhaus and other low-energy projects. He is a trustee of the AECB, the Association for Environment Conscious Building.

Paul is also active in promoting cohousing as a radical approach to providing better housing.  He is a director of the UK Cohousing Network and also of two local cohousing projects in Cornwall and Gloucestershire.
