Course Approach
  • Live, online, interactive teaching, with lots of opportunity to use the PHribbon software and ask questions.
  • This course focuses on how to use PHribbon to perform detailed embodied and operational carbon calculations, with exercises to practice these and receive general feedback. 
  • No previous knowledge of PHribbon is required, however, you will need to be fairly familiar with PHPP and it is important to have the PHPP (version 10 and above) and PHribbon software available to use.
  • There are exercises for you to do in between the 2 weekly sessions. The emphasis is to ensure that you understand how to tackle a range of situations and get reliable answers.
  • If it should happen that a student has to miss a session, they can watch the recording of the session.
  • There are 20 places available each time the course runs. Due to its interactive nature, the course requires a minimum of 5 students in order to run.
Why take this course?
  • Learn directly from the expert who developed the AECB PHribbon software, Tim Martel, with lots of opportunity to ask questions, practice use of the tool and receive feedback from Tim.
  • Considering and understanding the carbon impact and energy efficiency of our building and retrofit designs is essential to decarbonising our building stock. This course aims to upskill PHPP users to design buildings that can meet the RIBA Climate Challenge and LETI carbon standards, for embodied carbon and operational energy, and of course our AECB CarbonLite Standards.
  • Training in the use of PHribbon will allow learners to make good decisions for low carbon retrofit (and new build) in one step.
  • PHribbon is unique, as far as we know, in that it combines embodied and operational carbon on the same graph – it is all too easy to focus on one and miss the effect of the other (also because operational targets are often for energy, not CO2).
  • Save on design time and be able to show clients the carbon reduction benefits to projects, and the impacts of different material choices, early on.
  • Thinking has progressed a long way since PHribbon was first introduced. For example, we no longer regard the manufacturers view of the lifetime of a product as necessarily the right figure to use in calculations in some circumstances. In the course we will be giving examples of why those figures don’t work for some materials and how we have improved on this.
  • CO2 is modelled in accordance with the UK RICS (Royal Institute of Chartered Surveyors) methodology.
