SAC Review 07/31-08/01/ First, Do No Harm… o Although control of IEQ at the individual level has been shown to improve thermal comfort and IAQ, and enhance satisfaction and work output, large scale adoption is impeded by lack of attention to: u System-wide interactions and optimization u Cost implications (e.g., energy consumption) u Economic implications of high uncertainty of outcome o Large scale implementation is likely only if improvement in IAQ can be obtained with no increase in system-wide energy consumption, operating and fixed costs o It is not sufficient to attack this problem in a compartmentalized fashion – a systems approach is essential Optimal solutions require a cross-disciplinary, systems-driven approach…

SAC Review 07/31-08/01/ Response to 2005 SAC Report - 1 o Task teams have articulated their strategic focus -- their raison d’etre, and have defined the IAQ problems they are seeking to solve: u See Task Presentations o Justification for the “elaborate” programs have been reassessed and changes made. Simpler systems-level models are being used to focus the research: u For example, see Tabs E (CFD) and R (CHAMP) for justification of elaborate work, and Tab G for the use of simpler models. o Tasks are now better integrated and research teams working on related tasks conduct joint research meetings. u See, for example, Tabs E, F, G, H, I, and T. Other changes are covered in the task presentations that follow...

SAC Review 07/31-08/01/ Response to 2005 SAC Report - 2 o Task teams have conducted extensive literature reviews and networked with researchers conducting similar research. o A spectrum of modeling tools have and are being developed, ranging from simpler reduced-order models for optimization and control to very detailed models for exploring details within the PME or to “calibrate” the simpler models. u See, for example, Tabs E, F, G, I, R, and T. o The use of TVOC as a measure of IAQ is deemphasized and is now being explored only as a surrogate in ventilation control (as CO 2 is used in demand-controlled ventilation). u TVOC may correlate better with emissions from materials than CO 2. Other changes are covered in the task presentations that follow...

SAC Review 07/31-08/01/ Response to 2005 SAC Report - 3 o Ole Fanger has joined the SU faculty as a University Professor and is providing guidance from health and human response research. u Prof. Fanger is already engaged with our research team defining an expanded research portfolio in human response. o A $3M research facility (the STAR Center’s Carrier Total Indoor Quality (TIEQ) laboratory is being designed as part of the CoE-EES HQ building downtown (to be ready in 2008). u The TIEQ laboratory is aimed at the study of human response under controlled conditions. u Input from Profs. Fanger and Hedge has been received. o We have initiated discussions with EPA about exchange of students and faculty (both longer term and shorter term): u Some prospects for placement of some of our PhD graduates at EPA have been explored but did not work out because of Visa issues. Other changes are covered in the task presentations that follow...

SAC Review 07/31-08/01/ Response to 2005 SAC Report - 4 o The Task on the personal dust cloud (A. Ferro’s Task 2.A in EPA03) has been expanded through EPA04 funding to address SAC comments. o The Sensors and Controls Task (EPA03-T3) has been redirected toward a greater emphasis on CO 2 (and possibly TVOC) sensing for ventilation control in buildings with ubiquitous occupant-controlled micro-environments. u The system will be demonstrated in a 16-cubicle testbed to be completed in Link Hall in 2007 (ICUBE). o Greater emphasis in EPA04 is placed on a reduced-order modeling of the transport of contaminants in multi-zone buildings in which there is an interconnected combination of well-mixed zones (rooms) and open non-uniform spaces: u For system-level IEQ/Energy optimization and near-real-time control. Other changes are covered in the task presentations that follow...
