Redline Standards

Track Changes to ASHRAE Standards with new Redline Documents

Ever needed to see exactly what changed between a current ASHRAE standard and its previous edition?

Now you can.

ASHRAE has released dozens of standards as redline documents for sale online in the ASHRAE Bookstore. These redlines have been developed by Techstreet, ASHRAE's bookstore partner.

A redline indicates the changes made during the standards revision process between the active standard and its previous edition. Additions, deletions, and other formatting and content revisions are clearly displayed as underlined and strikethrough texts, ensuring all changes made between the two documents are quickly and easily identified.

Use redlines to:

• Identify updates in minutes, not hours
• Effortlessly implement changes to procedures, equipment and products
• Save time and resources

Purchasers who select the redline option upgrade will receive both the current standard and the redline version in print or digital format. Redlines compare the current standard to the previous original edition (OvO), excluding supplements.
