Development of MFHR Requirements

Multifamily High-Rise vs. Other Residential Buildings
MFLR and Single Family Development time ( Months) ENERGY STAR products for residential applications ENERGY STAR HVAC available RESNET provides verification Modeling easy and cost effective Building science well understood Two verification visits needed MFHR Development time (2 - 5 years) ENERGY STAR products not always available Multiple HVAC configurations (central and in-unit) Currently no national 3rd party verification organization Modeling is technical and requires special expertise Building science is not as well understood Multiple verification visits needed When developing the program’s requirements, it was important to acknowledge that there are many aspects of multifamily high rise buildings that differentiate them from multifamily low rise and single family homes. Some of them are procedural and others technical. For example, compared to single family homes and low-rise multifamily, residential high-rise buildings typically have: Significantly longer development and construction times; A larger design team, where diverse technical expertise must be coordinated; Multiple HVAC configurations, where large commercial systems may be specified; leaving less opportunity to incorporate ENERGY STAR qualified products; and Require more detailed modeling and verification guidance specific to this building type Therefore this building type would not be well served by simply applying the same requirements as the ENERGY STAR for New Homes Program. To overcome this barrier, EPA developed protocols specifically for this building type.

The Reference Standard
ASHRAE Minimum requirements for the energy-efficient design of high-rise multifamily buildings Appendix G Protocols for generating an energy performance rating for buildings that exceed the requirements of ASHRAE Program Standard LEED Mid-Rise Enterprise Green Communities The basis for the development of these requirements is ASHRAE Standard , as developed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers is an energy standard for buildings, EXCEPT low-rise residential, and describes the minimum requirements for the energy-efficient design of high-rise buildings. Similar to RESNET Standards, the ASHRAE Standard has a section that outlines the protocols for generating a performance rating for buildings that exceed the requirements of the standard. This section is found in Appendix G. This standard was also chosen because it is referenced by national programs such as USGBC’s LEED Rating system and Enterprise Green Communities.

Participant Roles and Expectations
Before we discuss the technical requirements of this program, it is also important to understand the key participants, the roles they each play and what is expected of them.
9
ENERGY STAR MFHR Developer Partner
Partner with ENERGY STAR Submit MFHR Project Application for each building/project Engage a licensed professional to validate submitted documents Commit to benchmarking building in Portfolio Manager Before a building is accepted into the program, the developer must sign a partnership agreement with EPA. The goal of this agreement is to clearly and consistently outline the terms and conditions for using the ENERGY STAR name and marks. Once the developer becomes a partner they may begin submitting project applications. Although signing a partnership agreement is a onetime occurrence, an application must be submitted for each building or project pursuing the ENERGY STAR. Other requirements of partnering with energy star include; Engaging a licensed professional to validate program submittals; and Committing to benchmarking your energy star qualified buildings in ENERGY STAR’s Portfolio Manager for minimum of 2 years More information on how to become an ENERGY STAR Multifamily high rise developer partner can be found on our website 9 9
10
Role of Licensed Professional
Work with project design team Coordinate modeling of Baseline and Proposed building OR guide design team through Prescriptive Path requirements Validate plan review to ensure final design meets requirements and necessary details are included in bid specifications Validate on-site inspections during construction to ensure measures are installed as specified Submit required documentation to EPA To protect the integrity of the ENERGY STAR brand, a licensed professional working on behalf of the ENERGY STAR MFHR Developer Partner must provide EPA with program specific submittals. These submittals are used to demonstrate that the program’s requirements have been met, that all prerequisites are included, and that each energy conservation measure is installed to specification. The licensed professional must be a Professional Engineer or Registered Architect and possess a current license and be in good standing. They should also have: A license in a discipline related to residential and/or commercial building systems; and have Working knowledge of ASHRAE Standard , ASHRAE Standard , and ASHRAE Standard It is essential that the licensed professional engaged by the developer partner work closely with the design team to coordinate modeling, validate plan reviews, and ensure that the energy conservation measures have been verified per the program’s testing and verification protocols. Although not a requirement, the Developer Partner may engage one or more third party energy consultants to help facilitate the process for earning the ENERGY STAR. Energy consultants can play a crucial role by helping recommend cost effective energy-efficient measures and construction techniques. They can also develop energy models and conduct the required on–site diagnostic testing and inspections to document that the building is eligible to earn the ENERGY STAR label. 10 10

Earning the ENERGY STAR
Now that we have an understanding of the roles of the participants, the next slides will explain how a multifamily high-rise building earns the ENERGY STAR.
12
Pathways to ENERGY STAR
Mandatory Requirements (Prerequisites) Performance Path Prescriptive Path Testing and Verification There are two paths to earning the ENERGY STAR for multifamily high rise projects. Developers may choose a prescriptive package of energy efficient measures developed by EPA, or use ASHRAE approved energy modeling software to determine energy savings of a customized set of measures. Regardless of which path is chosen, each building must meet certain minimum mandatory requirements and each energy conservation measure must be tested and verified to demonstrate that the program’s performance target has been met, that all mandatory measures are included, and that each energy conservation measure chosen by the design team is installed to specification. ENERGY STAR Benchmarking

Common Requirements for Performance and Prescriptive Paths
14
Meeting the Prerequisites
ENERGY STAR qualified appliances ENERGY STAR qualified lighting in 80% of light fixtures Occupancy sensors for lighting in most common spaces Right-sized heating and cooling equipment Total duct leakage for in-unit systems ≤6 CFM25 per 100ft2 of conditioned floor area (≤8 CFM25 per 100ft2 for units <1200ft2) Air-sealing to achieve infiltration <0.30 CFM50/ft2 of enclosure Double-pane, low-e windows Low-flow faucets & showerheads (≤ 2.0gpm) and WaterSense® toilets Continuous air barrier between conditioned/unconditioned spaces Ventilation per ASHRAE (apts. and common areas) *Not all Prerequisites have been listed here; see Prerequisite Checklist Some examples of these prerequisites are as follows: Wherever possible, ENERGY STAR qualified products should be installed. This applies to windows, ceiling fans, exhaust fans, appliances and any other product listed on the ENERGY STAR website. Since the ENERGY STAR labeling program doesn’t always apply to commercial grade products such as windows or central HVAC systems, it is understood that this is not always possible. 80% of light fixtures must either be ENERGY STAR qualified or have ENERGY STAR qualified lamps. The program also requires occupancy sensors for many common area lights. HVAC equipment must be sized properly and maximum leakage amounts for both duct leakage and infiltration have been established. Other prerequisites include double-pane windows, low-flow plumbing fixtures, including toilets, and compliance with ASHRAE , a standard that establishes ventilation rates that support acceptable indoor air quality in low-rise residential buildings. For the full list of prerequisites, refer to the Performance Path document or Prerequisites Checklist, within the Testing and Verification Worksheets. 14 14
15
Testing and Verification Protocols
Mandatory requirements for the inspection, testing and verification of components related to the building’s energy performance. The intent of the protocols is to verify that the construction documents & final building include all Prerequisites. measures used to achieve the Performance levels predicted by the model have been installed and perform as modeled. all measures specified by the Prescriptive Path have been installed. Changes to the initial design noted during inspections must be reflected in a revised model and submitted as the As-Built model. The other common requirement of both paths is verification and performance testing. This process is somewhat similar to the verification and testing required for the New Homes program, but expanded to accommodate building components unique to multifamily high-rise buildings. The ENERGY STAR multifamily high rise testing and verification protocols establish a consistent set of requirements for the inspection, testing and verification of components related to the building’s energy performance. The intent of the protocols is to verify that the construction documents and final building include the prerequisites, that each measure installed performs as expected, and that all requirements have been met. The protocols require documentation throughout the course of the project, beginning with plan reviews during the design stage. They also require that any change in design during construction be accounted for. A separate webinar dedicated to the Testing and Verification, or T&V, protocols is available.
16
Testing and Verification Worksheets
Mandatory Excel-based worksheets that document the results of plan reviews, inspections, verification, and performance testing. Provide inspection worksheets that can be used in the field that follow the Testing and Verification Protocols, but are organized for the convenience of the site inspector. Provide a central file to store building information relevant to all members of the design team: architect, energy modeler, site inspector, project manager, plan reviewer, etc. Must be submitted once prior to construction to document results of the plan review and once after construction is complete, to document the results of testing and verification. Similar to the checklists in the New Homes program, this program has developed documentation to support the testing and verification process. Rather than a PDF based checklists, mandatory Excel-based worksheets have been developed that document the results of plan reviews, inspections, verification, and performance testing. The worksheets follow each protocol, but are organized for the convenience of the site inspector and provide a central file to store building information relevant to all members of the design team, from the architect and energy modeler, to the project manager and site inspector. A separate webinar is available to explain how to use these worksheets.
17
Photo Template This Word-based template was designed so that pictures used to provide photo-documentation required by the T&V Protocols could be easily formatted and consistently reported. Photo documentation must be submitted to EPA at the end of construction as part of the As-Built Submittal The Photo Template need only be submitted for the licensed professional’s first three buildings that participate in the Program. EPA has also created a Word-based photo template so that pictures used to provide photo-documentation required by the Testing &Verification Protocols can be quickly and easily formatted and consistently reported. Photo documentation must be submitted to EPA at the end of construction. Once a licensed professional has successfully submitted 3 buildings to EPA, submission of a Photo Template as a component of the Testing and Verification Protocols is no longer required.
18
Performance Path Now that we have reviewed the mandatory requirements common between the two paths, let’s review the distinct differences between them.
19
Performance Path Requirements
Meet program Prerequisites Meet Performance Target 15% better than ASHRAE as defined by Appendix G and Simulation Guidelines Third-party verification and performance testing throughout construction Commit to Benchmarking in Portfolio Manager for at least two years The distinctive requirement of the Performance Path is the energy modeling component. At least two models must be created; the first represents the reference or baseline building based on ASHRAE , the second represents the proposed building design and ultimately the actual building, as-built. A building that can demonstrate 15% annual energy cost savings as compared to the ASHRAE baseline building, without the use of on-site power generation, is eligible to earn the ENERGY STAR. Unlike the New Homes program, the models are completed at the building level, not at the apartment level, and generally require commercial grade software such as eQUEST, DOE-2, Energy Gauge Summit, HAP or EnergyPlus. The modeler should verify that their modeling software is complaint with AHSRAE 90.1 requirements. The models developed must demonstrate that they have achieved this 15% Performance Target (both before and after construction) and must follow the protocols of Appendix G and the supplemental guidance provided by the EPA in the Simulation Guidelines document. A separate webinar provides an overview of the energy modeling process in greater detail. More information on the requirements of the Performance path can be found on our website as well as in the introduction to the performance path webinar

Performance Path Work Flow
ENERGY STAR MFHR Developer Partner submits project application Incorporate prerequisites and evaluate energy conservation measures (ECM) Generate models Conduct plan review Licensed professional submits Proposed Building Submittal Conduct inspections per the MFHR Testing and Verification Protocols If needed, corrective action(s) must be taken to ensure Prerequisites and ECMs are compliant Ensure As-Built Building meets Performance Target Licensed professional submits As-Built Submittal Building is qualified as ENERGY STAR Benchmark building Design Construction The flow of work from design to construction completion following the Performance Path is shown in this slide. In general, blue squares indicate steps in the work flow where an application or submission is required by the Developer Partner or the licensed professional working on their behalf. An exception to this is the step titled “Building is qualified as ENERGY STAR’ at which point EPA submits documentation to the developer partner qualifying the building as ENERGY STAR. The process flows as follows: During or before the design phase, the developer partner submits a project application to the EPA. Although projects can apply up until drywall has been installed; ideally, projects should apply as early in the process a possible. The next step involves the design team incorporating prerequisites into the design and modeling initial energy conservation measures that help achieve the 15% Performance Target. The energy modeler uses ASHRAE Appendix G and the Simulation Guidelines to develop the energy models of the baseline and proposed design to determine whether the Target was achieved. If it wasn’t, new measures are evaluated and modeled until a design is established that achieves 15% energy cost savings over the baseline, without on-site power generation, such as cogeneration, photovoltaics, or wind turbines. Once the proposed design is confirmed, all plans should be reviewed to ensure that prerequisites and measures are properly represented in the plans, prior to the start of construction or the start of the bidding process. At this point, the licensed professional submits the proposed building submittal which consists of the reporting summary and Testing and Verification Worksheets to EPA for approval. Throughout construction, inspections must be conducted following the Testing and Verification protocols. If not installed per design, corrective actions must be taken to ensure that prerequisites are being met and measures are installed correctly. At the end of construction, the energy model from the Proposed Design is updated to reflect the As-Built conditions. The As-Built can have different measures from the Proposed Design, as long as the 15% Performance Target is achieved and all prerequisites have been met. If a prerequisite is not met, the building cannot earn the ENERGY STAR. The licensed professional then submits the As-Built submittal which includes a reporting summary that reflects the final constructed building, as well as the Testing& Verification worksheets and Photo Template that document all the inspections. Once approved by EPA, the building is certified as “ENERGY STAR.” To ensure that the building is performing as expected and to reap further benefits through proper management, the owner or developer enters building energy consumption data into Portfolio Manager for a minimum of two years.

21
Prescriptive Path Now that we have an understanding of the roles of the participants, the next slides will explain how a multifamily high-rise building earns the ENERGY STAR.
22
Prescriptive Path Requirements
Install climate specific prescriptive requirements that meet or exceed Prerequisites Approximately equivalent to 15% better than ASHRAE , but no modeling Third-party verification and performance testing throughout construction Commit to benchmarking in Portfolio Manager for at least two years Unlike the Performance Path, the Prescriptive Path is the non-modeling path to earning the ENERGY STAR that doesn’t allow ANY trade-offs. This path has a list of prescribed energy efficient measures that meet or exceed all program prerequisites. Climate-specific envelope requirements and HVAC requirements are based on meeting or exceeding ASHRAE , a standard for green buildings, or ASHRAE When implemented, the Prescriptive Path should result in performance similar to a building meeting the 15% Performance Target in the Performance Path. More information on the requirements of the prescriptive path can be found on our website as well as in the introduction to the prescriptive path webinar
23
Prescriptive Path Work Flow
Design ENERGY STAR MFHR Developer Partner submits project application Design team incorporates Prescriptive Path requirements into the design Conduct plan review Licensed professional submits Proposed Building Submittal Conduct inspections per the MFHR Testing and Verification Protocols If needed, corrective action(s) must be taken to ensure Prescriptive requirements are compliant Licensed professional submits As-Built Submittal Building is qualified as ENERGY STAR Benchmark building Construction The flow of work from design to construction completion for a building following the Prescriptive Path is demonstrated in this slide. In general, blue squares again indicate steps in the work flow where a submission is required by the Developer Partner or the licensed professional working on their behalf, with the exception of the step titled “Building is qualified as ENERGY STAR’ at which point EPA submits documentation to the developer partner qualifying the building as ENERGY STAR. During the design phase, the design team incorporates all the Prescriptive Path requirements into the design. Before the project goes out to bid or before construction begins, the plans and construction documents are reviewed to ensure that all prescriptive requirements are properly represented in the plans. The licensed professional then submits the proposed building submittal which includes the T&V Worksheets to EPA Throughout construction, inspections must be conducted following the Testing and Verification protocols. If not installed per design, corrective actions must be taken to ensure that all Prescriptive Requirements have been installed correctly. If any prerequisite is not met, the building cannot earn the ENERGY STAR. However, if a Prescriptive Requirement is not met, but all prerequisites from the Performance Path have been met and an energy model demonstrates achievement of the 15% Performance Target, a building would be allowed to switch Paths and still earn the ENERGY STAR. At the end of construction, the licensed professional submits the as built building submittal which includes the Testing & Verification worksheets and Photo Template that document all the inspections. Once approved by EPA, the building may be certified as “ENERGY STAR” and the owner or developer enters building energy consumption data into Portfolio Manager for a minimum of two years.

Program Submittals Now that we have an understanding of the roles of the participants, the next slides will explain how a multifamily high-rise building earns the ENERGY STAR.
25
MFHR Program Submittals
To protect the integrity of the ENERGY STAR brand, a licensed professional must provide EPA with program specific submittals. These submittals are used to demonstrate that the program’s requirements have been met, that all prerequisites are included, and that each energy conservation measure is installed to specification.
26
Proposed Building Submittal
Proposed Building Reporting Summary (Performance Path Only) Testing and Verification Worksheets MFHR Submittal Validation Form The Proposed Building Submittal is used to ensure that the project design meets the requirements based on the Path selected and that they have been included in the construction documents. The licensed professional is responsible for submitting a Proposed Building Submittal, with an ENERGY STAR MFHR Submittal Validation Form to EPA for approval, prior to beginning construction. The Proposed Building Submittal includes the following documents: Proposed Building Reporting Summary (Performance Path Only) Testing and Verification Worksheets ENERGY STAR MFHR Submittal Validation Form
27
As-Built Building Submittal
As-Built Building Reporting Summary (Performance Path Only) Testing and Verification Worksheets Photo Template MFHR Submittal Validation Form The As-Built Building Submittal is used to ensure that the energy conservation measures chosen by the design team are installed to specification. After the final inspection, the licensed professional is responsible for submitting an As-Built Building Submittal, with an ENERGY STAR MFHR Submittal Validation Form, to EPA for approval. Once EPA has determined that the project has fulfilled all of the program requirements, the Developer Partner will be notified that the building has earned the ENERGY STAR and that it can be marketed and promoted per the ENERGY STAR Logo Identity Guidelines. The As-Built Building Submittal includes the following documents: As-Built Building Reporting Summary (Performance Path Only) Testing and Verification Worksheets Photo Template ENERGY STAR MFHR Submittal Validation Form
28
License Professional’s Guide and Submittal Validation Form
More information on submittals can be found in the Licensed Professional’s Guide to Earning the ENERGY STAR for MFHR Buildings document at By signing and stamping the ENERGY STAR MFHR Submittal Validation Form, the licensed professional is not guaranteeing performance of the operating building nor does it require that the licensed professional certify that the building will perform to any specified level. By validating the submission, the licensed professional is certifying that the information contained within the submitted documents is accurate and in accordance with the program’s guidelines, based on the conditions observed. For purposes of verifying the information contained in the program’s submittals, the PE may engage a representative to conduct all or part of the site visit while under his or her direction and control. However, the ENERGY STAR MFHR Submittal Validation form must still bear the seal and signature of the licensed PE or registered architect, who remains responsible for all work performed by others under his or her direction and control. For more guidance on submittals, see Licensed Professional’s Guide to the ENERGY STAR Label for MFHR Buildings.
