Admin Has everybody been able to access the webpage? Not all content on webpage Are class registration issues resolved?

Grading Oral Exam15% Software Mini-Project20% Final Project60% Participation 5% 100%

Final Project Major open-ended design effort based on themes of the class Work with a partner – I can assist with matching Spend ~100 hours/person on your project Opportunity to explore an area of interest Goal from this is to produce a professional 6- page conference paper.

Ground Rules 1.Topic must involve some component of design. 2.Topic must be substantially different from project done for other classes (current or past). 3.Content must be new or innovative. Some part of it should never have been done before. 4.Topic must relate to the themes of the class and be approved by me (via justification). 5.Topic must have substantial depth.

Topic Selection Projects from last year Very challenging to pick a good topic Common issues Specificity Depth Scope Feasibility Your interest is a good starting point Everybody who has done a good project has complained about the work involved

Tools Building Environmental Systems toolkit Particles VOCs Environmental parameters Flow/pressure Light sensor Others

Example Projects To give you some ideas Not meant to limit your creativity or scope Think about depth, rather than breadth

Past Successful Projects Many others also successful, just examples Radon emission from green concrete Importance of topic Lack of unification in literature Tractable analysis

Example Projects – Filter Bypass

Aromatherapy

Idea 1: Moisture Response Buildings are becoming sensibly more efficient Latent removal is not handled well by current equipment Moisture “insults” are a significant economic and health concern Goal: Measure moisture response in several residences

Benefits Design of novel latent removal system Recovery from leaks

Strategies Apply well mixed reactor model to water vapor Measure air exchange Eliminate sources Only unknown is net moisture absorption AKA moisture response

Issues Sample size Willingness of subjects Time consuming measurements AC interactions

Idea 2: Ventilation CO 2 is often used to measure ventilation Example: Austin smoking ordinance Goal: compare CO 2 to SF 6 (more robust tracer) Implications for measuring ventilation rate

Issues Access/human subjects approval SF 6 analyzer training Planning

Idea 3: Energy Efficiency Evaluation of “real” appliance efficiency Many appliances are rated based on ideal test procedure Test appliance under real conditions Goal: Does rating match predicted energy use? Issues Differentiation from product testing Control of all variables

Idea 4: UT Solar Decathlon Opportunity to work with other students to design a project with lasting impact Overcome barriers between engineers and architects Issue Need to think of well-crafted project Unsuccessful in the past

What About a Pure Design Project? Okay, but has to be crafted well Similar issues of depth, scope, and specificity
