Content of Module
- Information and recommendations for class instructors
- Teaching materials and script: PowerPoint presentation (PPP) with instructions
- Teacher’s manual: PPP with notes (questions, answers, interpretation) and supplemented with results sheets for class instructors
- GO tool based on MS Excel
The GO Tool is a tool for rating the energy efficiency of buildings. It can be used without special knowledge of building technology.
This module provides an understanding of the influence of density and windows on energy efficiency (heating and cooling demand). We will go over the influence of building geometry (building size, footprint, number of stories, construction method), as well as of windows (percentage of area, direction, shading, and window quality).
Suggested Teaching Order
Time for Step 1 - 4: about 10 - 15 minutes.
- Explanation of goal and sequence of material (the first PPP transparencies)
- Ask the students what they associate with the term “effective energy” and if they are familiar with any examples (including ones not from the building sector).
- Presentation of how effective energy and thermal balance are displayed in the Go Tool
- Ask students if they know any examples of heating loss or gain (and what factors influence this).
Time for Step 5: about 20 - 25 minutes (this step can optionally be skipped)
- Example of density (ratio of surface to volume) with an A4 sheet of graph paper and data from the PPP. Each student should process the data on their own. Questions, answers, interpretations, and suggestions for discussion topics can be found in the PPP notes. Results displayed in documents for class instructors.
Time for Steps 6 - 9: about 20 - 30 minutes.
- Ask the students to open the GO tool and to form small working groups as desired.
- GO Tool example of density. Information and tasks according to PPP. Results displayed in documents for class instructors.
- GO Tool example of windows and shades. Information and tasks according to PPP. Results displayed in documents for class instructors.
- Interpretation of the results, suggested discussion topics (questions to students).
Prerequisites for Implementation
- Graph paper: 1 A4 sheet per student
- MS Excel: ideally two students per computer
The prerequisite for this teaching module is having completed the GO-0 “Fundamentals” module, which includes information on how to use the GO Tool. This teaching module provides the basis for understanding the modules on Building Optimization, GO-2 and GO-3, as well as the modules by Alexander Passer (Technical University of Graz) and Heimo Staller (AEE INTEC).
