Energy modelling on Grasshopper using various plug ins

I am trying to explore a new Rhino+Gh workflow by applying the principles of low energy design and creating scripts to support them. To create a foundation, I would like some suggestions on varous energy modelling tools and plug ins which can help in verification and setting up of the building and energy model.

The inclusion of adding

  • input of U values to the fabric elements and adjacent spaces.
  • Setting up various systems for heating and cooling which can be translated into heating and cooling loads for the model post simulation
  • verifying the models using compliance methods such as CIBSE standards or ASHRAE standards
