A significant proportion of homes in Wales owned by Local Authorities and Housing Associations are classed as traditional. Addressing energy efficiency is fast becoming one of the most pressing issues for older, traditionally-constructed buildings. Upgrading traditional building fabric is notoriously complex, particularly where planning restrictions apply, and a holistic understanding of buildings, upgrade measures and occupant behaviour is required to ensure compatibility and appropriateness and to manage technical risks.

Woodknowledge Wales is partnering with The Green Register to offer a 50% discount for organisations and business based in Wales to attend a series of retrofit workshops run by retrofit expert Nicholas Heath.

This half-day seminar has been designed as a follow up to “Retrofitting Traditional Building 1: Principles and Practice” course. Participants will learn from a range of case study projects involving traditional and historic buildings, illustrating the key principles and details required for a holistic, whole-building approach to retrofit.


Completed and uncompleted projects are presented including domestic and non-domestic, urban and rural, listed and unlisted buildings, conversions and deep- to medium-level performance targets. Case studies include pre-retrofit performance analysis, hygrothermal simulations, detailed architectural drawings and post-occupancy monitoring where available to demonstrate the links between theory and practice.

Participants will have the opportunity to work through real projects, working in groups to identify retrofit strategies for a range of scenarios.


Wales based participants can benefit from a 50% discount on the course. Use code WKW21. Please note: Only residents with a verified postcode in Wales are eligible to benefit from this offer.
