Old House to Eco-house: A Guide to Retrofitting Historic Buildings

Our Old House to Eco-house: A Guide to Retrofitting Historic Buildings course series, comprising of three standalone one-day courses with a two-day intensive planned for winter 2025-2026, is aimed at those eager to gain the specific expertise required to design and implement sensitive retrofit strategies appropriate to older buildings.

Who are the courses suitable for?

  • Conservation officers and heritage planners
  • Architects, surveyors and engineers
  • Retrofit coordinators and assessors
  • Contractors and builders
  • Specialist consultants
  • Local authority and housing association staff
  • Owners, custodians and managers of historic buildings

What you’ll achieve at the end of the courses

Delegates will learn how to:

  • Identify appropriate insulation strategies for walls, floors and roofs
  • Evaluate glazing upgrade options for historic windows
  • Assess renewable energy technologies in heritage contexts
  • Utilise case studies illustrating successful retrofit interventions
  • Deliver moisture-safe, effective retrofit schemes, appropriate to the physics of the building

How are the courses delivered?

We offer the three standalone courses face-to-face on our RAU campus at Swindon, each over one day.

We adopt a blended learning approach, combining lecture-delivered theory with discussion of real-life case studies, to promote understanding of and engagement with course content amongst delegates.

If you would prefer to undertake all three courses over two consecutive days, we plan to run a two-day intensive in winter 2025-2026, delivered in-person at our Cirencester campus.

About the Course Leaders

The courses are designed by Marianne Suhr, Chartered Building Surveyor and co author of the Old House Eco Handbook. She will be lecturing alongside a host of nationally-recognised experts in retrofit and conservation, including Nick Heath, Bob Prewett and James Ayres who will bring real life case studies to illustrate a practical approach to decision making.

Course content

This course focuses on the scientific and practical aspects of insulating solid walls, floors, and roofs in older buildings.

Delegates will explore heat loss, airtightness, moisture risks, and breathability.

Sessions include technical presentations on insulation methods (internal, external, lime-based solutions), roof insulation options, limecrete floors, suspended timber floors, and moisture management.

 

This course focuses on upgrading and repairing historic window assemblies while preserving character and ensuring energy efficiency.

Delegates will explore repair techniques, linseed oil paints, moisture movement, secondary glazing systems, specialist glazing options and specifying new windows for historic buildings.

This course focuses on how renewable energy technologies can be incorporated into older properties.

Delegates will explore heat pump suitability, biomass options, solar panel economics, infra-red heating, and the future of wood burning in conservation contexts, as well as building physics and the importance of a fabric-first approach.

Course content from the above standalone courses will be covered over two consecutive days.
