PHPP Variants

PHPP is a powerful building energy modelling that provides accurate predictions of building performance.However, modelling multiple design options in PHPP can be tricky and/or time consuming. In PHPPv9, the Passive House Institute introduced the Variants worksheet to help address this issue. The Variants worksheet is a power tool that allows simultaneous modelling of multiple design options.This 2 week online course will explore how the Variants tool can be set up and used to achieve this and other objectives. Exercises will reinforce the learning.

Learning Objectives:

  • Navigate the Variants worksheet and correctly input data
  • Set up variables to adjust design parameters
  • Assess multiple design options simultaneously
  • Use the Variants worksheet to iterate a building design

Intended Audience: Intermediate and advanced PHPP users

Prerequisites: Experience with PHPP

Course Requirements: Laptop with a PHPPv9 software, and the PHPP manual.

Schedule: The course is structured into 4 lectures over the course of 2 weeks. You are invited to complete the course at your own pace. Access to the online platform will begin upon enrollment and will end 2 weeks after,however, all student resources including lecture slides will be available for download for future reference. The course is currently open for continuous enrollment.
