For "general office areas," federal OSHA recommends the use of ASHRAE 62.1-2004 Ventilation for Acceptable Indoor Air Quality. In Minnesota, we have a standard, MN Rules 5205.0110 Indoor Workroom Ventilation and Temperature, which deals with fresh air flow, heat stress, minimum temperatures and recirculated air. The standard, for those who are interested, can be found at http://www.revisor.leg.state.mn.us/bin/getpub.php?pubtype=RULE_CHAP_SEC&year=current§ion=5205.0110 - Diane Amell, MNOSHA >>> "Lazarski, Peter M."
10/8/2007 11:37 AM >>> NIST has a temperature reference for dimensional calibration http://ts.nist.gov/WeightsAndMeasures/Publications/gentechlength.cfm Also, the National Conference for Standardizing Laboratories has a publication, RP-7, for site selection and design of a metrology laboratory. Plagiarizing from "Guidelines for Laboratory Design", J. Wiley & Sons (1987), p.41, "The temperature in most laboratory buildings does not require close regulation, that is, no better than +/- 3 F." This book also refers to a draft ANSI-ASHRAE ventilation standard 86-62 (1986) which recommended air exchange rates for public, commercial and industrial areas. Local building codes were mentioned as sources. The CRC Handbook of Laboratory Safety, 5th edition has a large chapter titled Laboratory Facilities - Design and Equipment. I think there may be OSHA suggestions for temperatures of general office areas. The information contained in this e-mail message and any attachments may be confidential.

Any input would be useful. What is the target (set point) temperature, by space type. What is the acceptable range of temperature, by space type. What is the response time requirements of the temperature controlling system What is the target (set point) humidity, by space type. What is the acceptable range of humidity, by space type. What is the response time requirements of the humidity controlling system What is the minimum number of room air changes per hour, by space type. What is the maximum number of room air changes per hour, by space type. What are the pressure level requirements between / relative to each space type. What is the response time requirements of the pressure controlling system.
