______ 2012-2014 Cycle copyright release on file

3) Code: Indicate appropriate International Code (s) associated with this Public Proposal – Please use Acronym: ___IECC_____

If you have also submitted a separate coordination ch ange to another I-Code, please indicate the code: ________ (See section below for list of names and acronyms for the International Codes).

NOTE : Sections of the International Codes that have a letter desi gnation in brackets in front of th em are the responsibility of a

different committee than the committee normal ly responsible for that code. For instan ce, Section 301.1.4 of the IEBC has a [B] in front of it, meaning that this section is the re sponsibility of one of the IBC Code Devel opment Committees (in this case, IBC-S). Any proposed changes to Section 301.1.4 will be heard by the IBC-Structural committee.

Therefore, some code change proposals to Group B code text may be due by January 3, 2012, in order to be heard by Group A code development committees, and vice versa (proposed revision to a Group A code due January 3, 2013.) Please go to www.iccsafe.org/responsibilites for detailed information on Group A and Group B Code Development Committee responsibilities.

4) Multiple Proposals: A proponent shall not submit multiple code change propos als to the same code section. When a proponent submits multiple code cha nge proposals to the same section, the proposals sh all be considered as in complete proposals and not processed in accordance with Section 4.3 of CP #28. This restriction shall not apply to code change proposals that attempt to address differing subject matter within a code section.

5) Referenced Standards: Check here if this code change propos al includes reference to a standard that is not currently referenced in

one of the I-Codes. _____

NOTE : If a new referenced standard is proposed, a copy of the standard must be provided by th e proponent of the code change proposal. (This code change proposal will be considered incomplete and not processed if the new standard is not submitted in at least

consensus draft form in accordan ce with Section 3.6 of Council Policy CP #28.) If you have forwarded a copy of the standard(s) to ICC please check below: ______ Copy of new referenced standard(s) sent. (P lease check: Electronic ___ or Hard Copy ___)

6) E-mail address: Your email address will be published with your code change proposal unless you check here: ______

7) Information required: Be sure to format your proposal and include all information as indicated be low and in the Code Change Proposal Instructions’ section on Page 2 of this form.8) Format: Proposals should be sent to the office below via regular mail or email. An e-mail submittal is preferred, including an
electronic version, in either WordPerfect or Word (see proposal formatting section on Page 2 of this form).

Please use a separate form (see page 3) fo r each proposal submitted. Note: All code changes received will receive an acknowle dgment by approximately two weeks after the code change deadline. Pl ease contact the ICC staff listed be low if you have not received an acknowledgment by two weeks afte r the code change deadline.

The following items are required to be includ ed in your proposal (see form on page 3):

1. The proponent shall clearly state the purpose of the proposed code change

2. The proponent shall provide a logical explanation which clearly shows why the current Code provisions are inadequate or overly restrictive, specifies the shortcomings of the current Code prov isions and explains how such pr oposals will improve the Code.

3. The proponent shall substantiate the proposed code change base d on technical information and s ubstantiation. A minimum of two copies of all substantiating inform ation shall be submitted.

committee. This information will be included in the bibliography of the published code change proposal.

CODE CHANGE SUBMITTAL EXAMPLE



## Code: IBC –12/13

705.1

Proponent: John Doe, P.E., Acme Building Corporation, Inc, representing self

Revise as follows:

705.1 General. Each portion of a building separated by one or more a fire walls that comply complies with the provisions of this section Section 705 shall be considered a separate building.

Reason: A fire wall complying with Section 705 establishes the equi valent of separate buildings on either side of the fire wall. This proposal provides text that more succinctly states this purpose of a fire wall.

Cost Impact: The code change proposal will not in crease the cost of construction.

## Heat Recovery Ventilation

Description

Energy Recovery Ventilation (ERV) saves energy by using a heat exch anger to transfer heat between the

conditioned exhaust air stream and the unconditioned out door make-up air. The heat exchanger is capable

of transferring both sensible and latent heat between the two streams but the desiccant wheels used for

the transfer get saturated fairly qui ckly, thereby affecting performance. Therefore, we have considered

only sensible heat recovery systems in this concept, also commonly known as Heat Recovery

Ventilation (HRV) systems. Most HRV systems can recover 70%- 80% of the energy in the exhaust air 1

. We have assumed a conservative sensible effectiveness of 70% in this analysis.

Energy Cost Savings

Energy Recovery Ventilation yields ~ 3.9% national average energy cost savings over the 2012 IECC

code. Figure 1 below shows energy cost savings for ea ch climate zone. Energy savings increase as we

move from the warmer climate zones to the colder ones.

Figure 1: Energy Cost Savings for the concept over the 2012 IECC

Cost Effectiveness

The incremental cost of HRV systems vary by design. We have assumed a single-point HRV system in this
analysis. These systems cost an average of $1350 including installation 2 . The baseline system is assumed

to be a continuously operating exhaust fan. From the same source, thes e fans cost $70. These costs are

adjusted using location multipliers sp ecified in Table 1 below, to generate incremental costs by state. State

specific fuel costs are used in this analysis as specified in Table 2.
