computer simulations of humidity control approaches and system options in small buildings as a function of system type, building load characteristics, and ventilation rates for a range of climates (IECC/ DOE climate zones 1A through 6A). A range of occupancy loads will be simulated. Efficiency and cost analysis will be performed to provide clear ranking of the ability and effectiveness of various approaches and technologies to achieve indoor RH control. 04/07 – 07/08 Numerical Logics, Inc.

It is preferable to develop a primary calibration standard that can be replicated, owned, and used by each lab independently. However, it is possible that a primary calibration standard may be too expensive or difficult to use in each filter lab. Therefore a primary calibration standard, with secondary reference filters traced to the primary standard, may be a more realistic solution. If a secondary reference filter is used, traceability to the primary reference standard must be included by the manufacturer (see the attached, executed agreement to this effect), will provide verification of the design tool and will quantify the range of its utility. Finally, the optimization algorithm developed by 1246-RP will be used to optimize the gas mixture and operating conditions for the cryosurgical in order to demonstrate the utility of this tool to the cryogenics. 1472-RP 1476-RP Plan Goals Supported: D2, D3 09/07 – 08/09 University of Wisconsin Principal Investigator: Dean Tompkins TC 2. 3, Gaseous Air Contaminants and Gas Contaminant Removal Equipment Research Strategic Plan Goals Supported: B2 1457-RP By-Product Production from Photocatalytic Oxidation Associated with Indoor Air Cleaning Devices The research project will benefit ASHRAE and the general public as follows: If photocatalytic air cleaners are going to be used as an air cleaning option for Standard 62, then the output from these devices needs to be known in order to verify that the output is acceptable to the standard. With the incidents of asthma on the rise, especially for children, the characterization of the output from photocatalytic air cleaners needs to be known so that the potential for the creation of additional or increased asthma triggers can be limited. Provide data on the output compounds and levels from photocatalysis in indoor air that design engineers can use to produce improved devices for the remediation and control of exposure to disease and pollutants; in order to provide an optimal indoor environment for buildings, vehicles, and facilities with respect to comfort, productivity, health, and safety. Users of photocatalysis air cleaning devices will be more informed on the output of such devices. Some groups of VOCs have the suspicion of being carcinogenic even in very low concentrations. It should be known if these products are formed Development of a Calibration Referenec Device for Use With the Test Standard ANSI/ASHRAE 52. 2-2007 The contractor will design, construct, and characterize a calibration reference device, or devices, for use in ASHRAE Standard 52.2 test ducts. This device(s) will have accurately-known mid-range filtration efficiencies (i.e., between 20 and 80%) at particle sizes corresponding to those specified in ASHRAE Standard 52. 2-2007. Accuracy in the smaller particle sizes (i.e., 1–3 µm) is of particular importance. The contractor will develop a procedure to verify the filtration efficiencies of the device(s) based on accepted calibration procedures such as measurement with mono-disperse aerosol, use of high resolution electrical mobility and aerodynamic particle sizers, and agreement with theoretically derived particle removal efficiencies. The calibration device will have a known resistance to airflow allowing assessment of a laboratory’s airflow and resistance 09/07 – 08/08 White Box Technologies Principal Investigator: Joe Huang TC 4. 2, Weather Information Research Strategic Plan Goals Supported: A6, C1, C6, E2 1477-RP Development of Typical-Year Weather Files from the ISH Database of Historical Weather Data For 2,500 International Locations This project has a single objective of producing a large data set of 3,800 typical-year weather files for non-U.S. locations suitable for use in building energy simulations. For record-keeping purposes and to permit re-analysis or further improvements in modeling solar radiation, etc., the project will provide to ASHRAE the processed historical year weather files, and archive them in a format such as IWEC that would document the provenance of each data element, whether they are as reported on the raw weather files, interpolated or calculated.
