October 9th – Energy Code Compliance and Other Strategies for Achieving Greater Efficiency in NH’s Municipal Buildings: Tips for Town Managers, Local Code Officials, and Local Energy Committee Members, as well as interested citizens and professionals
Join the Local Energy Working Group for an informative webinar on building efficiency, the NH Energy Code and overcoming challenges when dealing with existing buildings – on October 9th, from 12:00 to 1:00 p.m.
- Kevin O’Maley (City of Manchester) and Michele Sopher (Town of Rye) will provide a blunt discussion of the challenges encountered within NH cities and towns that prevent cost-effective investment in municipal building efficiency improvements. Kevin and Michele will use specific examples, from projects completed their communities, on how barriers were overcome, projects financed, efficiency measures taken, and savings achieved.
- Jon Osgood (NH Public Utilities Commission Energy Conservation Coordinator) will talk about the specifics of the residential side of the code with reference to the application form to bring participants up to speed with what they should be looking for from their citizens. Jon will also provide some building science background and spend time discussing how energy committees can work with their town fathers and building departments to help increase awareness of the value the energy code and its contributions to communities over time. Information regarding key national energy code objectives will be provided along with a brief summary of the code development process nationally and in the state.
- Scott Albert of GDS Associates will facilitate; answering audience questions, and providing insights into policy and statewide initiatives.

DOE Seeks Comments on Building Energy Code Compliance Methodology
The U.S. Department of Energy (DOE) has issued a request for public comments on its methodology for assessing compliance with building energy codes at the local, state, and national levels. The Department is seeking feedback on a wide variety of questions, including:
- How should DOE define compliance with energy codes?
- What are the barriers to achieving compliance?
- What metrics should be used for measuring compliance?
- Do residential and commercial compliance evaluation studies require fundamentally different sampling plans and research methodologies?
- How could incentive funding be used to facilitate states to increase energy code adoption and compliance efforts?
- Is there a role DOE could play to support third-party evaluators?
Comments and information may be submitted to DOE on or before September 5, 2013. To view the full request for comments, which includes supplementary information, please visit (PDF) http://ow.ly/nKHW8.
U.S. Senate Delays Consideration of Energy Efficiency Bill – Will Now Begin Debate in September
The winding road of national energy efficiency legislation has taken another turn. The Energy Savings and Industrial Competitiveness Act (also known as Shaheen-Portman for its Senate sponsors) is widely considered to be the most important energy efficiency bill in nearly a decade, and is now scheduled to be debated as a first order of business when the U.S. Senate returns from its August recess in September. The Senate had previously planned to begin debate on this bill prior to their recess, but ran out of time due to fiscal year 2014 funding issues for transportation, housing, and urban development, and the need to confirm appointments to the Federal Bureau of Investigation and National Labor Relations Board.
Just before leaving, Senators Jeanne Shaheen (D-NH) and Rob Portman (R-OH) introduced a new version of their bill, which is now referenced as S.1392 (it was previously S.761). The new version is largely similar to that which cleared the Senate Energy and Natural Resources Committee with wide bipartisan support. Some of the biggest changes include the deletion of Title II, the Commercial Building Efficiency Financing Initiative, which was taken out to allow the bill to move forward and provide additional time for consensus to develop. Also among the changes was the addition of a new career skills program under Title I, which would provide grants to nonprofit partnerships who provide on-the-job training for obtaining industry-related certifications to install energy efficient buildings technologies.
The building energy codes section of the bill has not been changed.
In addition to the changes incorporated into S.1392, several amendments could be added to the bill, including the following:
- All-of-the-Above Federal Building Energy Conservation Act (S.1199) – Would change fossil fuel energy consumption reduction requirements, and add new energy efficiency provisions for federal buildings.
- Nonprofit Energy Efficiency Act (S.717) – Would establish a pilot program to award grants to nonprofit organizations for energy efficiency retrofits.
- Streamlining Energy Efficiency for Schools Act (S.1084) – Would establish the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy as the lead federal agency responsible for coordinating federal, state, and local assistance provided to promote the energy retrofitting of schools.
- Better Buildings Act (S.1191) (also known as Tenant Star) – Would build on the success of the U.S. Environmental Protection Agency’s ENERGY STAR for Buildings program and establish a voluntary new “Tenant Star” program to certify leased spaces in buildings as energy efficient.
While the Senate will begin debate on Shaheen-Portman in September, the chances of completing debate and passing the bill may be slim because of rumors of several controversial amendments that may be offered, and another big factor – time.
When Members of Congress return to Washington, they will have a mere 16 days to complete work on the 12 annual funding bills (none of which have been enacted) before the 2014 fiscal year begins on October 1st, or pass a continuing resolution, which would keep government spending at about current levels. Congress will also be faced with the often highly-charged issue of raising the debt ceiling. Both of these issues trump debate over Shaheen-Portman and could cause significant delays in the bill’s consideration and possible passage.
On the other side of the Capitol, the House has been, and will likely continue waiting for the Senate to act before moving on their version of Shaheen-Portman, known as McKinley-Welch (H.R.1616).

Question: What’s the deal with duct testing under the IECC 2009 code? How can I make sure I pass the inspection? -Drew, Exeter NH
Many studies have shown that visual inspection of duct seals in residences is not enough. Code now requires a pressure test. Pressure testing ducts as required by the 2009 IECC is far superior to visual inspection and will definitively confirm that duct leakage is kept to a low level. Building Energy Codes Program experts estimate that pressure testing ducts in new residential construction will reduce energy consumption in new homes by up to 10% on average and potentially much more in some homes.
Section 403.2.2 of the 2009 IECC states that the sealing of ducts must be verified by a duct pressure test. This test involves using a fan to force air into the duct system and measuring how much air leaks out through cracks and holes (the registers are taped closed for the test). A duct pressure test is not required if the air handler and all ducts are located inside the building thermal envelope. The requirements for how to seal ducts are given in Section M1601.3 of the International Residential Code, and apply regardless of the location of the ducts.
The code allows considerable flexibility in the required test. It can be conducted by anyone, including the installer or a third party. It can be done either after rough-in of the ducts or at the completion of construction (i.e., after drywall has been installed and finished). There are separate requirements for testing at rough-in, depending on whether the air handler has been installed at the time of the test. The post-construction test can measure either the “total leakage” of the ducts or the “leakage to outdoors” (the fraction of the total that leaks outside the conditioned space).
The allowable leakage rates are expressed in terms of airflow (cubic feet per minute or CFM) per 100 ft² of conditioned floor area, when duct registers or boots are taped/sealed and the duct system is pressurized to 25 Pascals (0.1 inches w.c.). Maximum leakage rates for the various testing options are as follows:
Maximum CFM per 100 ft² @25 Pascals
At rough-in, air handler not installed
At rough-in, air handler installed
Post-construction, leakage to outdoors
Post-construction, total leakage
The drawbacks of rough-in testing include less accuracy as leaks in the boot assembly cannot be fully measured because drywall is not yet installed. Also, it is only possible to measure total leakage whereas leakage specifically to the outdoors can be measured when the house is completed.

Some Tips to Ensure Compliance
It is often helpful to imagine that instead of filling the duct system with air, you are filling it with water – and you absolutely don’t want any water to leak out of the system anywhere. Ideally, the same care you would use to seal the ductwork to be water-tight should be used when you are sealing the system to pass an air pressure test.
Some other useful tips:
- Make sure that all supply and return ductwork is tightly sealed with mastic or foil tape, not duct tape. This includes all the seams and anywhere a connection is made.
- Make sure the seams around the air handler unit itself are sealed tightly with foil tape. Also, ensure that the filter slot is gasketed and seals tightly upon closure.
- Use dedicated ductwork for all supply and return lines; i.e. do not use building frame such as wall-stud cavities or floor joist cavities as ductwork.
- Seal all duct boots that penetrate the sub floor to the sub floor with mastic or foil tape.
- If flex-duct is used, ensure that it is not kinked or compressed.
