Just added in the library: Measuring the Extent of Thermal Bridging in External Timber Framed Walls in New Zealand.

While you may mostly be looking at existing housing, this research shows how adding extra timber to wall framing has the potential to reduce the amount of insulation and therefore increase heat loss.

The research found the average percentage of timber framing compared to wall area was 34%, much higher than the 14–18% framing content generally assumed by regulators and the industry.
