GBC V2 Launch May-June 2022

Green Building Calculator Version 2: BIM without a 3D Model

MS Excel-based, open-book, multi-functional design, decision tool and calculator:

  • Choose fuel to get: In-use energy, carbon and running costs
  • Embodied energy, embodied carbon, sequestered carbon

Choose or switch between U values and other targets:

  • Design Dictated: Form Factor
  • Legal minimum: UK or any national regulations
  • Design Standards: AECB, CL, CLR, PH, EnerPHit
  • Campaign Targets: LETI, ACAN, RIBA, TfL
  • Checks and confirms U values meet targets or warns if not

Choose:

  • From 39 readymade elemental assemblies, with all components in order
  • Which components or layers apply to your elements
  • Materials and it populates data cells for calculations

Summary sheet: (illustrated)

  • Component, Element and Whole building losses
  • Emphasises disproportionate heat losses to enable review of specification choices

Bill of quantities: without a QS

  • Allows cost planning, quotation collating, tendering, build costs
  • With cost and carbon data, intelligent value engineering is possible

Green Building Calculator launches Version 2 at Futurebuild 2022 in Digital Impact Zone at stand L68.

GBC V2 is MS Excel-based, open-book, a multi-functional design tool and calculator, it adds whole building embodied energy, embodied carbon, sequestered carbon and costs to the existing in-use energy, carbon and costs of Version 1. 

GBC V2 calculates Form Factor to help set U value targets, it engages user’s choice of regulated, design standards, or campaign targets, including: UK or any national regulations; AECB, CL, CLR, PH, EnerPHit; LETI, ACAN, RIBA, TfL, etc.

GBC V2’s elemental assemblies allow choice of components, materials or products, checks, confirms U values meet targets or warns if not. 

Summary sheet emphasises which elements have disproportionate heat losses to enable review of specification choices.

GBC V2 includes a bill of quantities to allow cost planning, quotation collating, tendering; with cost and carbon data, intelligent value engineering is possible.
