Our 'Old House to Eco-house’ course series is aimed at those eager to gain the specific expertise required to design and implement sensitive retrofit strategies appropriate to older buildings.

A series of three standalone one-day courses, we also offer a condensed, two-day intensive version.

Who is the course series 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 course series

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

A CPD Certificate of Completion

Delegates, on completion, will receive a CPD Certificate of Completion endorsed by the RAU.

How is the course series delivered?

We offer the three standalone courses face-to-face 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 offer a two-day intensive, 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.
