Green Retrofit Calculator version 1 preview

Brian Murphy, aka BrianSpecMan, founder of GreenSpec – and now creator of the Green Building Encyclopaedia, demonstrated the key features of his emerging design and decision tool, Green Retrofit Calculator [GRC V1]. GRC V1 was developed from Green Building Calculator GBC V2

GRC Version 1 provided information regarding

  • Survey forms to collect building and previous intervention data
  • English and Scottish House condition survey developed as 30 house types to choose from
  • Analysis forms to collate building data and proposed intervention
  • Risk assessment between existing building and proposed interventions
  • Target U values: Regulations, Conservation and STBA v Design Standards or WUFI limits
  • Insulation different materials thicknesses to meet U values
  • Elemental Assembly R & U value calculator
  • Whole building energy consumption
  • Elemental heat loss percentages
  • Fuel choice
  • Carbon in use
  • Energy in use

GRC has been created for home owner clients, but is useful for architects, developers, contractors and property managers alike.

It’s an impartial, easy to use, value for money product that can result in our buildings having a positive environmental impact, rather than contributing to terminating our planet for human occupation!
