[Equest-users] Fwd: Fw: Mandatory Provisions 5.4

[Nick Caton]

Hi Ty,

Here's a paraphrase:

"Where you are required to have insulation, you must install it per section 5.8.1.1-9."

Turning that around:

"Where you are not required to have insulation, 5.8.1.1-9 does not come into play."

I don't believe this is a "follow either A or B" statement - more like "if A, then B."

Hi Everyone,

I am quite confused between what the ASHRAE 90.1 and the user's manual tell us about Building Envelope Mandatory Provisions:

5.4 Mandatory Provisions
"5.4.1 Insulation. Where insulation is required in Section
5.5 or 5.6, it shall comply with the requirements found in Sections
5.8.1.1 through 5.8.1.9." - ASHRAE 90.1-2007


Insulation (§ 5.8.1)
"The first set of mandatory requirements
addresses the proper installation and
protection of insulation materials. Issues
that are covered include compression of
insulation, installing insulation on sloping
ceilings and around recessed equipment,
and protecting insulation from physical or
moisture damage."- ASHRAE 90.1-2007-User's Manual


Does this mean that we could use insulation that is not as efficient as indicated in Table 5.5-1 through 5.5-8 as long as it complies with Section 5.8.1.1 through 5.8.1.9?

Your thoughts are highly appreciated.
