1. IEQ Project Intro to Stage 3 Hypothesis investigation: Study design & Field measurements EH522, Fall 2010

2. Timeline Sep 16: Meet with the manager(s) of your assigned microenvironments Sep 23: Stage 1; initial building walk-through –Oct 11, 9am: Stage 1 results to be submitted into course website DROPBOX Oct 14: Stage 2; occupant investigation/interviews, statement of hypotheses; study design –Oct 25, 9am: Stage 2 results to be submitted into DROPBOX Oct 28 & Nov 4: Jose Vallarino will train students on the use of IEQ instruments Nov 4: Stage 3; field measurements, investigation of hypotheses –Nov 22, 9am: Stage 3 results to be submitted into DROPBOX Nov 18: Stage 4; mitigation strategies, conclusions –Dec 6, 9am: Poster (pdf) to be submitted into DROPBOX Dec 8, 5pm: Please submit your presentation slides into the course website DROPBOX Dec 9: Group presentations –10-15mins each group, with 5mins discussion

3. Goals Your initial walk-through and occupant interviews will have led you to develop 2-3 hypotheses. Stage 3 will involve the design and implementation of field measures to test your hypotheses.

4. Important for HSPH Group Place informative folded tents on each table in the dining area, stating: –“EH522 Class Project: Indoor Environmental Quality Assessment Under Way” At the end of your measurements, please make sure you remove these.

5. Expectations Reserve equipment by speaking with Jose Vallarino after today’s class. Jose may also be contacted via email: –jvallari@hsph.harvard.edujvallari@hsph.harvard.edu Plan to learn & use: –Thermal Comfort: Globe temperature, Mean radiant temperature (if we measure surface temperature we can estimate it), RH, T. –Air flows/Ventilation: How do we measure airflow ( hot wire anemometer, flow hood, van anemometer, etc). –Sources: Real time vs integrated methods: –Gaseous: »CO, CO 2, NOx, VOCs, Ozone, etc –PM: »Real time: Sidepack, P-Trak. etc »?an integrated impaction system.

6. Expectations Your report will include: –Outline stated hypotheses from prior stages to be tested –Study design: A description of testing instruments (why each type of instrument was selected?) Please specify the types, locations (include outdoor measures for comparison), timing and frequencies of measures. –Measurements and analysis. –Interpretation of measurements.

7. Expectations Your group findings should be presented in a clear, concise document –5 pages max for text –single-spaced –12-size font –with appendices for tables, figures, etc… Due 9am on November 22 –Online DROPBOX

8. Any questions?
