Oversized Boilers Not Warranted by Manufacturers

Weatherization is not alone in being concerned with heating system sizing. Boiler manufacturers are adding a notice (see below) in the installation manuals about oversized systems. Oversized systems can lead to excessive cycling and warranties being voided. Below is an example of a notice provided by one manufacturer. Over sizing causes the issues noted above plus it prevents boilers from reaching optimum energy savings.

Example of notice used by boiler manufacturers


CO and PVC Furnace Piping Inspections

Checking PVC exhaust and combustion air piping during audits and inspections is highlighted in a recent news story out of Colorado. The Aspen Daily news describes an unfortunate story of a family that succumbed to carbon monoxide poisoning. The exhaust piping was easily disconnected because it was not properly primed, glued or sealed and was not securely attached, supported or braced in any way.

Cherry Picking Not Allowed – Even with Reduced Funding and EAPWX

There appears to be some confusion among auditors about the DOE requirement to audit all possible measures. The misunderstanding is that only some measures need to be considered due to lower funding levels.  All measures must be considered. The DOE requirements remain the same. 

Auditors must consider all measures that reach the SIR threshold. Modeling all the data entry tabs in the WA audit is required no matter what funding source is being considered. All measures achieving a SIR > 1 are to be completed unless the funding source used for that dwelling restricts measures, e.g. EAP/WX. When measures are restricted due to the use of EAP/WX or other funding restrictions, the measures should be deactivated by un-checking the measure box in the WA software. The measure may remain active if CIP or other supplemental funding is available. Contact your field monitor if there are areas of concern.

Incidental (General) Repairs

Our office frequently receives questions about incidental (general) repairs and how they may be used. DOE recently released WPN 12-09: Weatherization Assistance Program Incidental Repair Measure Guidance. This WPN is explicit regarding the use of these funds. The WPN refers to 10 CFR 440.3 where incidental repairs are defined as “those repairs necessary for the effective performance or preservation of weatherization materials.”

The WPN points out incidental repairs must be associated with “their need and relationship to a specific energy conservation measure (ECM) or group of ECMs.” DOE also reminds us that WAP is not a rehabilitation or general repairs program. Definitions of incidental repairs, health and safety measure, energy conservation measure, and other related terms are included in WPN 12-09 along with examples. 

To avoid disallowed costs for the misuse of incidental (general) repairs, read through WPN 12-09 along with the accompanying FAQs (.pdf).

Contact your field monitor if you have questions about incidental (general) repairs.


Commerce will release requests for proposals (RFPs) for administrative training in August. It is expected that client education and project management courses will be available early this fall.

ASHRAE training is important for everyone since we must begin meeting ASHRAE 62.2 starting on September 1, 2012. Fond du Lac provided four trainings this year. Commerce is talking with Fond du Lac about providing at least one more class. Auditors and inspectors must attend this training course. If other ASHRAE 62.2 trainings are available, they will be acceptable for meeting training requirements. The course attended should be at least four hours long. 

After you attend a training course, be sure to report course attendance to Mark McLaughlin at
