Please contact Emily Toto EToto ashrae. Project Committee List Servers for Standards. ASHRAE Standard establishes a simple means of referring to common refrigerants instead of using the chemical name, formula or trade name. It also established a uniform system for assigning reference numbers and safety classifications to refrigerants.

Standards that are on continuous maintenance are continuously updated through addenda and ASHRAE makes these available free online. When it is determined that a published standard, guideline, code, or user's manual contains an error or errors, an errata sheet may be published at the discretion of the Manager of Standards.

The F-factors for slab-on-grade floors are defined in Standard Consult Appendix A Table A6. These F-factors are acceptable for all slab-on-grade floors, but you need to make sure the insulation is rated and applied accordingly. While ASHRAE's performance requirements for slab-on-grade insulation has shifted over time, the basics of the standard's permitted applications of slab-on-grade insulation have remained largely unchanged for the past several editions of Standard In hopes of offering some clarity, the figure below depicts acceptable and unacceptable slab-on-grade insulation applications.

This information applies at least as far back as the edition of standard. Only two states have an energy code less stringent than Standard Figure 1: Slab-on-Grade Insulation Applications.

Technical Support Document for Version 3. The U. A review of any given construction assembly characteristics overall U-value, insulation R-value should also include the thermal mass of the construction assembly lightweight, heavyweight.

From a design-engineering perspective, there are three common outcomes from such review: Compare against rules-of-thumb. The common rules of thumb will vary across climates and space-functions e. This can vary from company to company and even from engineer-to-engineer within the same company. Many factors can influence the safety factors, including distribution losses, regional construction quality, space operation and start-up capacity.

Building decarbonization is an industry trend, talking point and hot topic. Learn More. The celebration included a ribbon cutting and remarks from special guests, donors, and President Schwedler.
