Facilitated by the developer of the OAA’s next-generation free and open-source OBJECTIVE (TEUI3) calculation tool and framework, Architect and Building Science lecturer, Andy Thomson, M.Arch, OAA. Workshop counts towards OAA Continuing Education Structured Hours (self-reported) and 2hr Mandatory Climate Action Continuing Education.

Societies and/or Schools or private companies will provide the venue for this 2-4hr session, AV equipment and any food/refreshments. Participants will be asked to bring building data for any building they would like to model using OBJECTIVE. The session will include a 1hr Introduction, followed by Q&A and Demonstrations, followed by a review of Case Studies and/or workshop to troubleshoot use of the tool on buildings the participants would like to try modelling in the tool, concluding with drinks/informal peer-to-peer conversations.

Speaker fee, workshop equipment and prizes are partially funded by the OAA’s public sponsorship fund.

Introduction (60 minutes)

Keynote Overview and Introduction to the reason for the development of the OBJECTIVE TEUI Building Energy Rating System and Tool, it’s key values, functions, and the difference between Targeted and Actual Energy functions with an brief overview of the UI and its 50+ user-inputs. Q&A and Break.

Lab Component (30 minutes)

Interactive Building Science Demos with Water: A model for Air Leakage, and a Model for Area to Volume and Ventilation Considerations, including group discussion & prizes.

Imagine you are a Building (60 minutes)

We are all building science experts insofar as we get dressed every day for different weather and we are loaded with sensors to detect ‘comfort’ with incredible precision. If only we could translate this knowledge to our design skills, with the help of a tool to quantify these effects. This experiment is designed for both laughs and a visceral translation of the fundamental concepts of Building Science, Human Comfort and survivability. Demo will include a play-by play completion of the TEUI 3 tool to review inputs.

The ‘User-Experience Stress Test’ – A model for;

Insulation Levels, Walls, Floor, Roof, providing an area and RSI value line by line
Glazing, Solar Gain, Glare and Shading, we can’t turn off the Sun but we can block it’s rays
Airtightness, Wind and Exposure effects, stressing the importance of adhesion of the WRB/AVB
Ventilation Rate, Free Cooling, RH% and Temperature monitoring with referenced values (Inside/Outside) and Setpoints

followed by:

Free the Volunteer’ Participants Race the Clock to determine where in the TEUI3 interface variables can be adjusted to ‘release’ their colleague from the ‘envelope’ components and climate impacts.

Case Study Review, Group Exercise and 5-minute Presentations (90 minutes)

TEUI3 Calibration, Design and Inputs are continually refined by feedback from buildings with real-world utility data. Small groups will be assigned buildings from the TEUI3 Case Study Guide document with varying levels of building geometry, envelope thermal values and utility data to attempt to complete a TEUI3 baseline document. Groups will then determine ways the building can reach Net-Zero Ready and finally Net Zero Carbon (operational) status, and what it might take to get to Net Zero Lifetime Carbon (the 2050 target). Participants will pay special attention to input tool-tips and related info-blogs (where available) to complete ‘unknown’ variables.

Groups will;

Determine Case Study Building Baseline from Key Values Sheets (save baseline file!)
Determine an Operational Energy & Carbon Improvement Scenario to get to Zero Emissions (be prepared to discuss costs/complexity/difficulties)
Determine what may need to be done to deliver a Zero ‘Lifetime Carbon’ building

Conclusion: Presentation of Findings (max. 5-minutes each)

End, Social/Drinks/Peer Discussions
