Who can carry out a NatHERS for Existing Homes assessment?

Short Answer

Only assessors accredited and trained under the NatHERS for Existing Homes program can perform these assessments.

Full Answer

Not all NatHERS assessors are qualified to assess existing homes. Assessors must complete extra training and follow new protocols that ensure the data collected on-site is reliable and repeatable. This includes rules for measuring unknown elements like insulation and construction type using evidence-based methods.

Why this matters

A rating issued by someone without the correct training may not be valid for government programs or sustainability reporting.
