Research proposal / Philip Nlorris USA / Page 2 designed, the literature was reviewed, protocols to perform the research were established including procedures for measuring human response, possible occupant groups for the long-term study were identified, some of the instrumentation was acquired, and the Science Advisory Committee was formed. After detailed discussion at the meeting with the Science Advisory Committee on March 25,1992, it was decided to modify the approach originally proposed. Rather than starting with studies involving long-term occupancy, the first series of studies will focus on system evaluation with simulated load and with short-term human occupancy loads for two reasons: 1) the increased potential for obtaining credible results with short-term loads, and 2) the difficulty encountered in identifying potential long-term occupants. The objective for the second period of the project is to complete construction of the test facility; install, commission, and begin evaluation of the systems. The scope of the work for the second period is limited to the Tasks described in this proposal. However, opportunities for Improvement of system performance are anticipated. Therefore, as these opportunities are identified, they will be described in a separate proposal and submitted for your consideration. Procedure While construction is being completed for the test facility (i.e., Phase II of the Research and Demonstration Facility, RDF If), a revised protocol will be developed for tests involving both simulated loads and short-term occupancy. During this period, modeling of system performance will be developed and data will be acquired in the test room in Richmond to obtain initial comparison between vertical displacement and ceiling supply systems. These data will also be used to validate the models, which will then be used to predict the performance of these systems under different configurations. After construction is completed at RDF li, baseline data on the HVAC systems will be measured and influences of simulated loads and short-term occupancy, Including smokers, wili be evaluated. Policy To assure objectivity in this project, the external Science Advisory Committee will continue to review and advise on the protocol to be followed. Procedures regarding the use of human occupants as sources of thermal and contaminant loads will be reviewed and approved by the Human Subject Committee at Virginia Tech before testing with them commences.

Protocol Development Finalize protocols for data collection for tests at Philip Morris's Richmond facility, and the tests to be conducted In the RDF ii, Including the effect of simulated loads and short-term occupancy, induding smokers. A summary of the protocols/procedures will be submitted with the progress reports (November 15, 1992 and February 15, 1993). Task 2. Development of Performance Criteria . Develop performance criteria for systems, induding energy and economic performance. The performance criteria will be based on existing standards and guidelines for acceptable Indoor air quality and thermal comfort, induding air temperature and velocity distribution, draft, vertical air temperature differences, air distribution effectiveness, contaminant removal effectiveness, particulates, TVOC, etc. (November 15, 1992). Task 3. Modeiing of Systems Develop models for air-flow characteristics that account for thermal and contaminant loads and seasonal variations. This Task will be completed in 4 subtasks: 3.1 Develop models. Four types of models will be developed and integrated (January 15, 1993): a) Three compartment model for occupied zone, upper zone, and boundary zone. b) An energy and mass balance model for the HVAC systems. c) Room concentration distribution model. d) Life-cycle cost model.

Quality Assurance and Quality Control Monitor and control the performance of the Instrumentation and the quality of the data. Task 5. Database Development Develop and standardize a database for all data acquired from environmental, system, and planned human response measurements. The database will be compatible with the software to be used for analysis. Task 6. Testing at Richmond (February 1, 1993) The vertical displacement and ceiling supply system at Philip Morris's Richmond facility will be evaluated on three basic room characteristics: thermal, air distribution, and contaminant removal. Thermal characteristics will be evaluated by measuring air temperature and air velocity distributions. Air distribution will be evaluated by measuring the air change effectiveness using trace gas technology. Contaminant removal will be evaluated by measuring contaminant concentrations in the breathing zone of the occupied space and In the exhaust air of the room (contaminant removal effectiveness). The contaminants to be evaluated will Include particulates, C02, nicotine, and contaminants simulated by tracer gas. These three basic room characteristics will also be evaluated as a function of: total air flow rate, percentage of outdoor air, difference between supply and room air temperature, thermal loads, supply and return air device locations, water vapor,

The data will give the first comparative analysis of two air distribution systems under different conditions. Furthermore, these data will be used to validate models. Task 7. Acquisition and Development of Instrumentation (February 15, 1993). The remaining Instrumentation required for the primary measuring station will be procured. The secondary measuring stations will be designed. Task 8.

Results will be compared with predicted values obtained through the validated models. :

PROPOSAL to Philip Morris, USA for Continuation of FINAL 9 October 1992 Evaluation of displacement ventilation and conventional variable air volume systems for indoor air quality control submitted by Indoor Environment Program College of Architecture and Urban Studies Virginia Tech t Second period: May 16, 1992 to March 15, 1993 Construction of Research and Demonstration Facility (RDF phase ii), installation, and evaluation of systems Objective The overall objective of this study is to evaluate the effectiveness of displacement ventilation and other control technologies in providing acceptable Indoor air quality (IAQ) when internal contaminants, including environmental tobacco smoke (ETS), are present. Introduction Within the scope of this research project, internal sources of airborne particulates, gases and vapors are assumed to exist within occupied spaces. Consequently, this research will focus on comparing and analyzing the performance of two HVAC systems: A"conventionai" VAV system; and a vertical displacement system known as FACT (Filtered Air Control Technology). The first period of the research project (May 1991 - Aug 1992) focused on planning the overall study, including the design of the facility and the development of protocol. It was planned that after initial systems tests, occupants would be selected and would work for extended periods in the two test spaces served by different HVAC systems. During the first period, the facility was
