WHAT JUST HAPPENED!
This question is being asked all over the state of North Carolina with the New North Carolina Energy Conservation Code (NCECC) taking effect March 1st, 2012.
The background is by Executive Order
embraced by the DOE, US Conference of Mayors, ASHRAE, and AIA established
THE2030 CHALLENGE which is designed to change the energy codes every three years with 10%
improvement in efficiency each cycle until 2030 a structure will have NET ZERO
net energy use.
The 2012 NCECC is a six year jump in this process. The NCECC
is currently more stringent than Energy Codes in Oregon and Washington and is
in the top five most stringent in the US. This sweeping change in the way
Development and Construction is probably more impactful than Phase II Storm
Water.
I won’t bore you with technical details. Suffice it to say this Code looks at the
total structure when calculating compliance. The key concept here is Old School was Prescriptive Compliance and the New is Performance Compliance. No more my roof insulation
material is R-19 and my wall insulation material is R-14 and I pass. Plus this Code
moved the compliance target. For example the roof goes from R-19 to R-30CI and it dictates how
to achieve thermal value and other goals such as air infiltration (CI). Compliance would not be complete
until the walls and slab are included in a total calculation that includes
doors, windows, vents, etc…
WHY WOULD I BLOG THIS WARNING ?
Well because from the Financial end as a Lender replacement costs just took a substantial leap up and
because some material suppliers such as Metal Building Brokers are located
outside North Carolina your clients could purchase substantial materials that
could not the used to construct. Example: the old r-panel screw down (direct
attachment to purlins) is out due to the gap required for the insulation and
the disallowing of the pinch down at the purlins. Simply stated a
pre-engineered package with the fasteners, trim, and panel for this type roof
cannot be constructed in NC anymore, a whole roof system thrown away.
As an Insurance Provider or Appraiser in
addition to substantial upward adjustment of replacement costs, pricing information from valuation services located outside of NC may
not have adjusted for these sweeping changes. I am thinking of RS Means and
Marshall Swift among others.
For my Clients and
Design Professionals I can only say we have to start over at square one in
planning any projects whether new construction or remodel and both Residential
or Commercial
For my Friends in
the business who have survived since 2007. This is game changing sweeping
transformation to how we design, construct and think. Failing to compensate for
this Code is a path to failure.
My goal has been to raise questions for you on what this
means to you based on how you relate to the construction industry. From that
point I have I have provided some links to guide you to research to become
knowledgeable on the issue. Construction has now become highly complex with interwoven sometimes conflicting regulations and requirements. My job is to guide my clients to sucessful outcomes.
