III. NEW BUSINESS
1) Discussion of Residential and Commercial cost associated with the 2021 Code.
John Simon Presented data related to residential costs associated with the 2021 IECC
as written. Costs were provided by R Anthony and Habitat for humanity based upon a
1400 sf dwelling. It appears the extra cost for this size dwelling will be in the
neighborhood of $10,000(Tis is on top of an approximate 20% increase in costs due to
volatility, supply chain issues and inflation). As previously noted it is projected to
decrease energy usage approximately 8%.
John Neyens explained the difficulty estimating commercial costs associated with the
2021 energy code changes as designers will approach the requirements in a multiplicity
of ways. What is clear is the code has become more complicated and will require more
scrutiny by designers and reviewers. The new certification and testing requirements will
certainly add significant cost. At this time the 2021 ComCheck software is still not
available. This software is relied upon to streamline design, compliance modeling and
review. The expectation is this software will be available prior to enforcement of the new
codes on October 1, 2022.
ยท There was a general consensus among all present that, given the CAP adopted by
the City of Columbia, the 2021 IECC would be adopted as written but the adoption of
net-zero appendices should be postponed. Reasons to postpone net-zero requirements
include;
-Size/cost of on-site power production facilities to meet net-zero requirements.
-Lack of methods to procure off-site renewable energy.
-Lack of Community Renewable Energy facilities to contract with.
-Complicated legal processes associated with Renewable Energy Purchase Contracts
or leases requiring a duration of not less than 15 years.
