AccuRate Sustainability

AccuRate Sustainability Now available!
AccuRate Sustainability contains all the functions of earlier versions of AccuRate, but also has a series of additional features including streamlined and simplified data entry and more assessment modules to save time, improve productivity and broaden the services you offer. AccuRate Sustainability has an annual subscription pricing model and included support. The added flexibility and depth of functionality ensures AccuRate Sustainability sets the software standard for residential sustainability assessors.

Here's what's new in AccuRate Sustainability

  • Improved windows and roof windows options. The default windows and roof windows have been updated with AFRC certified ratings and options. Custom windows libraries may also be available from third parties.

  • Increased number of constructions. The limitation on the number of all building constructions has been increased from 10 to 20.

  • New engine. Better handling of openings in internal and external walls and partitions has been incorporated. Improved modelling of roof spaces and sub-floor zones.

  • New shading schemes. Improved horizontal and vertical shading modelling for eaves, pergolas and wing walls.

  • Sectioned wall input. Specify horizontal stacking of wall constructions where one facade has multiple constructions.

Those assessors new to AccuRate Sustainability will also notice:

  • New modules. In non-rating mode, additional modules allow assessors to add value to their business by offering clients valuable sustainability information in addition to the regulated heating and cooling assessment. Modules include lighting, space heating and cooling, hot water, water and embodied CO2.

  • Thermal bridging capability.

  • Automatic calculation of roof/ceiling zone. Speed up the assessment process by having AccuRate Sustainability calculate the volume of the roof space.

  • Automatic zone volume calculation. AccuRate Sustainability no longer requires assessors to manually enter volumes for regular shaped rooms, this removes a common source of error and simplifies the rating process.

  • Ability to mirror building. Assessors can quickly change orientation and flip the building to speed up assessment of multi tenancy units, apartments or large housing projects.

  • Simple roof type selection. AccuRate Sustainability comes with a new roof calculator which takes care of the laborious manual work in calculating the roof space for common roof types. This tool increases assessor efficiency and consistency.

  • Included support All license holders receive access to construction libraries, technical support and software updates. Premium support is also available for purchase.
