GBE Calculators (Navigation)

  • We all have to use them from time to time
  • Some times we rely on manufacturers to provide U value calculators
  • Students need to get to understand their designs better, so do Architects.
  • Design and Decision Tools (D&DT) need them embedded
  • UK Government TSB has funded a dozen £1m D&DT software developments which will be commecial software
  • In Canada the goverment is paying for RetScreen to develop free to use national calculators
  • In the UK BRE have the monopoly on compliance calculators: SAP, SBEM
  • In Germany they have Passivhaus PHPP
  • AECB’s CarbonLite interprets Passivhaus PHPP for UK climate and energy mix
  • Doing calculations long hand seems incredibly time consuming so GBE turns them into Excel calculators whereever possible and is making them available to download and use
  • GBE is also creating GBE Datasets to work with GBE Equations and GBE Calculators

    I was wondering if you ever considered hanging the structure of your blog?
    Its very well written; I love what you’ve got to say.
    But maybe you could a little more in the way of content so peoplle could connect with it better.
    You’ve got an awful lot of text for only having 1 or two images.
    Maybe you could space it out better?
