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

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.

Subject: [DCHAS-L] laboratory/office environmental control questions
I have been challenged by my engineering group to consider the
following
questions as they pertain to a mixed use office/laboratory building.
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.
Kind regards,
