Our prices depend on how much work will be required to complete assessment and produce any reports. The categories based on the house size and other definitions of work type are explained below.

Small  

Single storey house, 1-2 bedrooms, max 100sqm

Medium  

Up to 4 bedrooms, max 180 sqm

Large    

Over 180 sqm or 5 or more bedrooms. As there is no limits to the size, large project prices are indicative only and need to be confirmed before booking the assessment

Base Assessment

NatHERS: the assessment of the house as drawn on building plans for building permit approval or as originally supplied for design stage scenarios

Scorecard & other reports: the assessment of the house as is (as recorded during original inspection)

2nd Assessment 

Banks offering loan products for energy efficiency upgrades may require Scorecard assessment before and after upgrade. Or if the rating (assessment) must be repeated for any reason. In NatHERS, apartments and units have often identical or mirrored floor plans and use the same building materials.

Certificate

Cost of certifying the assessment with relevant authorities and issuing official rating certificate. Separating assessment and certification costs allows to explore various scenarios (variations) without having to certify each time a change is made in the design.

Variations 

Changes to the base assessment to compare different scenarios or upgrade options. Can be used in NatHERS assessments on design stage to identify most cost effective option to achieve required start rating. In Scorecard, variations can be used to identify most effective upgrade path. Variations can be small or complex. Complex variations are when changes are made to the zones (rooms) ie changing in size, adding or removing rooms and may involve almost as much time as it takes to model the entire house. Small variations are any other changes to the design (floor covering, adding/removing/changing doors or windows etc)

Zone

A room in the house or part of the room with significant difference to the rest to treat it as separate area. Room, area and zone are equivalent names in terms of the assessment.
