MEEA Webinar: Energy Efficiency Appliance Standards

Join us Wednesday, October 22, 2014, 1:00 – 2:00pm CDT for a webinar on Energy Efficiency Appliance Standards. Register here. 

National energy efficiency standards for appliances, lighting products and equipment specify the minimum energy and/or water efficiency levels of specific products. The U.S. Department of Energy is responsible for reviewing and updating all national efficiency standards to keep pace with technological change. While national standards apply to products manufactured or imported for sale into the U.S., state legislatures can also set standards that apply to products sold or installed in a given state.

Marianne DiMascio, with the Appliance Standards Awareness Project, will present an overview of national appliance and equipment standards finalized this year. In addition, she will provide an overview of state standards activity, the energy savings achieved from existing standards, and the potential for additional savings from new and updated standards. Rich Hackner, with GDS Associates, Inc., will provide a Midwest perspective and demonstrate how federal appliance standards impact Ameren Illinois’ energy efficiency program offerings for C&I prescriptive and custom programs.

DOE’s New Solution Center Shares Proven Energy Efficiency Program Strategies

The U.S. Department of Energy (DOE) is launching the new Better Buildings Residential Program Solution Center which highlights successful strategies and solutions used by residential energy efficiency programs across the country. Through the Better Buildings Neighborhood Program, Home Performance with ENERGY STAR®, utility-sponsored programs, and other initiatives, hundreds of communities have been working to promote energy efficiency upgrades in homes and multifamily buildings. To share the innovations and lessons learned from these efforts, DOE has compiled a one-stop shop for residential energy efficiency program administrators and home performance professionals.

The Solution Center is organized into a series of handbooks—concise online resources with step-by-step guidance for planning, operating, and evaluating a residential energy efficiency program. Each handbook draws on the experiences of multiple programs and contains resources such as tools, calculators, publications, videos, presentations, and case studies.

  • Market Position & Business Model handbooks describe how to assess current and potential demand for energy efficiency products and services (e.g., home energy assessments and upgrades; loans or financing products; contractor training) and what factors influence this demand.
  • Program Design & Customer Experience handbooks explore how to create a customer-centric process by bringing together marketing and outreach, incentives, financing, contractor coordination, and data collection to provide products and services that customers want.
  • Marketing & Outreach handbooks discuss ways to spur demand for home energy upgrades by understanding target audiences and using effective messaging, marketing and outreach tactics, and attractive program offers to motivate them to act.
  • Financing handbooks provide guidance for creating loan products that help customers pay for home energy upgrades in ways that are also affordable for programs and contractors.
  • Contractor Engagement & Workforce Development handbooks describe how to design a program that provides value for contractors by aligning with their business cycles and supporting workforce training.
  • Evaluation & Data Collection handbooks outline ways to develop effective data collection and evaluation strategies in order to understand the effects of a program.

To ensure the Solution Center remains a valuable resource for programs and home performance professionals into the future, DOE invites users to explore the new tool and suggest additional content or materials for possible inclusion by emailing BBRPSolutionCenter@ee.doe.gov.

MEEA Presents at ACEEE 2014 Summer Study on Energy Efficiency in Buildings Conference

Isaac Elnecave, MEEA’s Senior Policy Manager presented at the 2014 ACEEE Summer Study on Energy Efficiency in Buildings . This year’s conference theme was “The Next Generation: Reaching for High Energy Savings,” and Isaac presented his paper entitled, “I Want CANDI: Establishing a Utility Code Compliance Program in Illinois”.  CANDI is an acronym of the program participants – ComEd, Ameren, Nicor, DCEO and Integrys.  The paper was co-authored by Hammad Chaudhry, of Nicor Gas, and Stefano Galiasso, of the Energy Resource Center at the University of Illinois at Chicago.

Isaac’s presentation discussed the establishment of an Illinois utility claimed-savings program that applies a consistent approach towards measuring energy code compliance, attributing savings, allocating costs, as well as determining savings and cost effectiveness. This program allows utilities to invest in energy code compliance enhancement efforts and then claim a portion of the energy savings created from the more energy efficient buildings being constructed due to the program.  It is one of the first energy code compliance claimed-savings programs in the country.  It is also the first program in Illinois to involve all investor-owned utilities and the state energy office.  The paper and the conference presentation discuss how these various issues were addressed and how the initial idea was formed into a coherent, comprehensive program.  The paper is available in the Proceedings of the 2014 ACEEE Summer Study on Energy Efficiency in Buildings.

Retrofit Chicago Commercial Challenge Program Updates with Impressive Statistics

The City of Chicago’s Commercial Buildings Initiative is a voluntary program launched in 2012 as part of the overall Retrofit Chicago program. This Challenge provides support and recognition of existing commercial buildings over 200,000 square feet that commit to a 20% energy reduction within 5 years. On Friday July 18, members of the MEEA staff attended the two year update of this program led by Mayor Rahm Emanuel and Chief Sustainability Officer Karen Weigert. Other attendees included advocate organizations, building owner participants, and stakeholder partners.  Notable highlights included a 7% energy use decrease across all buildings (where data is available) when compared to the 2010 baseline, and a tripling in participation from 12 buildings covering 14 million square feet in 2012 to 48 buildings covering 37 million square feet as of July 2014.

Buildings participating in the program range from 7-117 years old, and include 24 commercial office spaces, 10 hotels, 11 university buildings, 2 cultural institutions and 1 residential multi-family building. Through participation and completion of the program, these buildings will utilize cross-sector outreach and technical resources of program partners, tailored peer support, as well as utility energy efficiency incentives in order to realize the cost savings and avoided greenhouse gas emissions associated with permanent reductions in energy consumption.  On the whole, participating buildings have received over $2 million in utility incentives resulting in annual savings of 21 million kWh and an equivalent of $1.5 million in utility bill reductions.

By using benchmarking to track energy use in existing buildings and target opportunities for efficiency improvements, MEEA supports the efforts taken by the City of Chicago and applauds its progress in realized energy savings and participation recruitment. Many participants have utilized the Building Operator Certification, a MEEA-administered training program for building operators that leads to an average energy savings of $12,000 per facility. While these training services are offered to participants in the Commercial Buildings Initiative, MEEA also administers these trainings throughout the entire Midwest region.

Best practices from the Retrofit Chicago Commercial Buildings Initiative were highlighted at the program update event and available in an on-line document, but perhaps most noteworthy was testimony from a participating building owner who made the business case for participation by emphasizing the relatively quick return-on-investment for these energy efficiency upgrades.  For buildings this large, a 20% reduction in energy use represents a major cost with savings that add up quickly when compounded over the lifetime of the upgrade investment(s). As participants begin reporting on these savings, MEEA hopes more and more Chicago building owners will jump on board.

Michigan Moves Forward With Updated Statewide Residential Energy Code

The Michigan Residential Code Review Committee has voted to approve a new statewide building energy code for residential buildings, with an expected effective date of January 2016.  The new code is based on the 2012 International Energy Conservation Code (IECC), with some modifications listed below.

MEEA has analyzed the economic potential of adopting the 2012 IECC, with the Michigan-specific modifications.  We have found that a newly constructed 2,400 square foot home in Detroit will use an average of 725 fewer kWh and 358 fewer therms per year if built to the 2012 IECC, as modified in Michigan, compared to the current energy code.  This would result in the average homeowner saving around $320 annually in utility bills.  It is important to note that these energy and cost savings will continue for the life of a building, which can be 50 – 100 years or more.

In addition to yielding economic benefits to homeowners, the proposed energy code will result in higher quality, healthier, and more comfortable buildings.  In particular, the requirement for buildings to have air tight enclosures and well-sealed duct systems, verified with diagnostic tests, will help realize these benefits to air quality.  A building enclosure that is tightly sealed, combined with a proper ventilation system, will prevent unwanted movement of air into and out of the building.  This reduces the load on space heating and cooling equipment and increases the indoor air quality of buildings.

The efficiency improvements in the new code include: a requirement for tight building enclosures, tighter duct systems, diagnostic testing to verify the air infiltration and duct leakage rates, higher efficiency windows and added crawl space insulation.  Importantly, all of these measures and their energy efficiency improvements are most easily incorporated during the design and initial construction phase.  It can be cost prohibitive to improve these measures in existing buildings, which is why it is crucial for these measures to be addressed in the building codes that regulate new construction.

Using the median number of one and two family residences built annually over the previous ten years in Michigan (12,915 homes[1]), multiplied by the potential annual energy savings per home in Detroit (37.1 MMBTU), there would be an annual statewide energy savings of around 480,000 MMBTU from building to the new 2012 energy code for residential buildings.  That is equivalent to the amount of energy used by almost 2,500 homes, and utility bill savings would be over $4 Million annually for homeowners.

In 2013, the Department of Licensing and Regulatory Affairs convened the Residential Code Review Committee to address the issue of updating the statewide energy code.  The committee was comprised of code officials and others in the state’s building industry to consider the entire International Residential Code, including Chapter 11 on Energy Efficiency.  MEEA supported this process by providing educational materials to the committee and attending several of the meetings when energy efficiency was on the agenda.  MEEA provided comparisons that showed differences between the current and proposed codes, energy savings analysis, and third party reports from Department of Energy.

Below are the amendments Michigan is planning to incorporate into the residential 2012 IECC:

  1. 1.      Wall Insulation (prescriptive table only):
  • Climate zones 6 and 7: R-20 or R-13 + 5

 

  1. 2.      Basement Insulation:
  • Climate zone 5: R – 10 / 13

 

  1. 3.      Ceiling Insulation:
  • Climate zone 5: R – 38

 

  1. 4.      U-factor Table (R402.1.3):
  • Modified to reflect changes to prescriptive table

 

  1. 5.       Air Leakage:
  • Requires blower door test to confirm air leakage of less than 4 ACH50 (prescriptive)

 

  1. 6.      Duct Leakage:
  • Requires duct leakage test when portion of duct system located outside conditioned space. Must meet one of the following leakage requirements:
    • o Postconstruction Test:

- Total Leakage: 4 CFM25 / 100 sq ft.

- Leakage to Outside: 4 CFM25 / 100 sq ft.

  • o Rough-in test:

- Total Leakage: 4 CFM25 / 100 sq ft.

 

MEEA Releases Residential Energy Efficiency Research

MEEA recently released a publication titled, “Evaluation of Missed Energy Saving Opportunity Based on Illinois Home Performance Program Field Data: Homeowner Selected Upgrades vs. Cost-Optimized Solutions.”  This research was conducted in partnership with the Department of Energy’s Building America program, which MEEA participates in as a team member of the cold-climate focused Partnership for Advanced Residential Retrofit. The study evaluates what is actually being done, within specific housing types, when homeowners choose to participate in the Illinois Home Performance with ENERGY STAR® (IHP) program, sponsored by the Illinois Department of Commerce and Economic Opportunity and administered by MEEA.

This publication expands on previous research and compares the measure packages installed during the first 800 IHP retrofits to the measure packages recommended as cost-optimal by Building Energy Optimization™ (BEopt) modeling software. The cost-optimal measure packages were identified in previous research for fifteen Chicagoland single family housing archetypes, called housing groups.

In this study, 800 IHP homes have been matched to one of these fifteen housing groups. The typically-installed measures for each housing group have been modeled using BEopt to estimate energy savings. For most housing groups, the differences between recommended and actually-installed measure packages are substantial. By comparing actual IHP retrofit measures to BEopt-recommended cost-optimal measures, missed savings opportunities are identified in some housing groups; in addition, valuable information is obtained regarding housing groups where IHP achieves greater savings than BEopt-modeled, cost-optimal recommendations.

Overall, the study finds not only that for some housing groups, the average IHP retrofit results in more energy savings than would result from cost-optimal, BEopt-recommended measure packages, but also that linking home categorization to standardized retrofit measure packages provides an opportunity to streamline the process for single family home energy retrofits and maximize both energy savings and cost-effectiveness.

This research is valuable to MEEA’s programs team because it represents an instance where primary data has been extracted from the program and analyzed to provide valuable feedback. To read the full report, please click here.

Minnesota Residential 2012 IECC Adoption

The Minnesota Department of Labor and Industry (DLI) has completed the process to update the statewide building energy code for residential buildings.  The new code is based on the 2012 International Energy Conservation Code (IECC), with some modifications listed below.

MEEA has analyzed the economic potential of adopting the 2012 IECC, with the Minnesota-specific modifications.  We have found that a newly constructed 2,400 square foot home in Minneapolis will use an average of 1,300 fewer kWh and 550 fewer therms per year if built to the 2012 IECC, as modified in Minnesota, compared to the current energy code.  This would result in the average homeowner saving around $540 annually in utility bills.  It is important to note that these energy and cost savings will continue for the life of a building, which can be 50 – 100 years or more.  The United States Department of Energy has also done an analysis with similar findings and concluded that a homeowner with a 30 year mortgage will realize a positive cash flow in the first year, after considering initial construction costs and annual utility bill savings.[1]

In addition to yielding economic benefits to homeowners, the proposed energy code will result in higher quality, healthier, and more comfortable buildings.  In particular, the requirement for buildings to have air tight enclosures and well-sealed duct systems, verified with diagnostic tests, will help realize these benefits to air quality.  A building enclosure that is tightly sealed, combined with a proper ventilation system, will prevent unwanted movement of air into and out of the building.  This reduces the load on space heating and cooling equipment and increases the indoor air quality of buildings.

Other efficiency improvements that are included in the proposed energy code are higher efficiency windows and added basement insulation.  Importantly, all of these measures and their energy efficiency improvements are most easily incorporated during the design and initial construction phase.  It can be cost prohibitive to improve these measures in existing buildings, which is why it is crucial for these measures to be addressed in the building codes that regulate new construction.

Using the average number of one and two family residences built annually over the previous ten years in Minnesota (14,956 homes[2]), multiplied by the potential annual energy savings per home in Minneapolis (59 MMBTU), there would be an annual statewide energy savings of over 880,000 MMBTU from building to the new 2012 energy code for residential buildings.  That is equivalent to the amount of energy used by almost 4,000 homes, and utility bill savings would be over $8 Million annually for homeowners.

In 2012, the Department of Labor and Industry convened a stakeholder working group to address the issue of updating the statewide energy code. MEEA participated in this process, along with many organizations in Minnesota’s construction industry. Homebuilders, manufacturers, energy experts, building officials, and utility companies were some of the groups that participated and offered input on how to update Minnesota’s statewide building energy code. The group eventually sent recommendations on what the new code should look like in order to yield the most cost-effective benefits in the form of energy and utility bill savings for Minnesota’s building owners and operators. The code that was adopted by the Department of Labor and Industry in April, 2014 was largely a result of this process.

Below are the modifications Minnesota made to the model version of the residential 2012 IECC:

1.      Wall Insulation (prescriptive table only):

  •  - Climate zone 6: R-20 or R-13 + 5
  •  - Climate zone 7: R-21

2.      Basement Insulation:

  •  - R-15 continuous, with minimum R-10 exterior
  •  - Additional requirements for walk-out basements
  •  - R-10 continuous exterior insulation if tested air leakage rate < 2.6 ACH50

3.      Duct Insulation: Vapor retarder required for unconditioned spaces

4.      Specific requirements for basement moisture mitigation

5.       Specific ventilation requirements (only allows balanced)

While the public comment period is over, there are still several procedural steps that must be completed to finalize the administrative rulemaking process.  DLI will be submitting the code to the Office of Administrative Hearings (OAH), where it will be reviewed for a determination of reasonableness.  After that, the Governor’s office will be able to review the code, with a chance to veto.  Once those steps are completed, the code will be published in the state register and become effective 180 days later.

Learn about Deep Energy Retrofits at the 2014 BuildingChicago/Greening the Heartland Conference

A panel discussion in which Steve Kismohr, Senior Technical Manager from MEEA, assisted in organizing and will be a co-presenter was recently accepted to present at the 2014 BuildingChicago/Greening the Heartland Conference! The conference will take place at the end of September in Chicago and will bring together building professionals from around the Midwest.

The presentation will include a total of four panelists, including Henry Kosarzycki from the State of WI and AIA National Director, Tate Walker from Energy Center of Wisconsin, and Kurt Zimmerman from Zimmerman Architectural Studios (ZAS), as well as Mr. Kismohr. The panel is entitled, “Diving into Deep Energy Retrofits: A Holistic Approach to Greater Energy Savings.”  The same group presented during a half day workshop on Deep Energy Retrofits for members of AIA WI in April to great success.

Inspired by the publication, “Deep Energy Retrofits:  An Emerging Opportunity,” co-published by the American Institute of Architects and Rocky Mountain Institute, this panel will highlight both the opportunities available and best practices existing building owners can follow to achieve significant energy use savings within existing buildings. The discussion will speak to the opportunities of deep energy retrofits (DER) – renovations of existing buildings which have the goal of achieving greater than 50% energy savings.

The outline of the panel discussion will focus on the process of completing a Deep Energy Retrofit:  acquiring and compiling an existing building’s energy use data (aka the process of benchmarking), analyzing the building’s current equipment, processes and patterns of use (an energy audit), and finally, using an integrated team of architects, engineers, financiers, and energy modelers to greatly reduce the building’s energy use – sometimes by greater than 50% (goal setting, analysis, and project development). The presentation will conclude with Kurt Zimmerman demonstrating how this process was incorporated into the build-out/extensive remodel of the ZAS office (offered as a case study).

This panel takes the idea of building energy benchmarking, as is currently required in the cities of Chicago, Minneapolis and under development in other Midwest cities, and demonstrates how the information gathered in these processes can be utilized to achieve significant building energy use savings when applied in a holistic manner.

For more information on whole-building energy usage data, benchmarking, and data disclosure, please contact Steve Kismohr, MEEA’s Sr. Technical Manager at skismohr@mwalliance.org or 312.784.7257.
