Laws and Regs
GREEN BUILDING ACT
The Green Building Act (GBA) (§ 6-1451.01 - § 6-1451.11) establishes high-performance green building standards for public and private construction projects. If a project falls within the scope of the GBA, and associated regulations, compliance with the GBA will also satisfy compliance with the 2013 and 2017 Green Construction Code.
Anacostia Waterfront Environmental Standards Act
The Anacostia Waterfront Environmental Standards Act enhances the green building requirements of the Green Building Act.

Interpretations and Guidance
The Green Building Division has provided training and guidance for Third Party Plan Review and Inspection Agencies regarding the DC Green and Energy Codes. Content can be reviewed here.
2013 DC Commercial Energy Conservation Code
Performance Pathway Guidance
The energy code has multiple compliance options for project teams. Additionally, DCRA has created two new pathways for project teams to show compliance when using an energy model for 3rd party green building programs. (e.g. LEED, Enterprise Green Communities) A project team may submit the same 3rd party energy model to demonstrate energy code compliance, provided the model exceeds ASHRAE Appendix G standards as follows:
- Energy model 18% better than ASHRAE 90.1-2007 Appendix G
- Energy model 5% better than ASHRAE 90.1-2010 Appendix G
Energy Modeling Guidance
There are many types of energy modeling software that may be used to show compliance with the Energy Code. DCRA requires that the project teams provide sufficient input and output documentation for the baseline and proposed spaces to document the weather location, envelope, mechanical, electrical, plumbing systems, costs, and energy usage for comparing the model to the drawings. Below are two common software programs used by energy modelers and the reports requested for each.
- eQuest Reports: SV-A, PV-A, BEPU, ES-D, LV-H, LV-I, LV-B,LV-C, BEPS,ERV Energy Recovery Summary
- Trane Trace Reports: ASHRAE 62.1 Ventilation, Building Areas, Building U-Values, Economic Information, Energy Cost Budget, Library Members, Plant Information, Entered Values, System Component Selection Summary, Psychrometric, Room Checksums, Walls by Direction, LEED Summary Report (if applicable)
2013 DC Residential Energy Conservation Code
New systems must meet the requirements of Systems - Section R403.
- Section R403.2.2.1 - Sealed air handler. Air handlers shall have a manufacturer’s designation for an air leakage of no more than 2 percent of the design air flow rate when tested in accordance with ASHRAE 193.
- Section R403.6 - Equipment Sizing: Heating and cooling equipment shall be sized in accordance with ACCA Manual S based on building loads calculated in accordance with ACCA Manual J or other approved heating and cooling calculation methodologies.
NOTE: A Manual S Report must accompany the Manual J Report.
- Section R403.6 is not required for HVAC units that are at a nominal maximum size of 1.5 tons (18,000btuh). Although not required, a load calculation is recommended to establish room by room air flow rates.
Please review our load sizing Guidelines designed to help project teams better understand compliance.
ACCA approved software can be found at www.acca.org/standards/approved-software
Residential Energy Certificates
All properties subject to the 2013 Residential Energy Conservation Code must post an energy certificate in each dwelling unit, per Section R401.3 Certificate.
The energy certificates must be permanently affixed on the electrical panel in each house/dwelling unit. As an alternative, DCRA will allow permanently affixed energy certificates to be placed in mechanical closets provided that they are clearly visible from the doorway.
The energy code dictates what information, at a minimum, must be included on the certificate. DCRA has provided two versions of compliant certificates. This version can be printed 4 to a page on sticker paper; this version has space to add company-specific logos and contact information.
2013 DC Green Construction Code
Per Section 220.127.116.11 of the 2013 DC Building Code, commissioning is required for projects subject to the 2013 DC Green Construction Code that are either (1) new construction^, (2) level 3 alterations, or (3) level 1 and 2 alterations 50,000 square feet or greater*. Commissioning shall be done in accordance with Section 611 and Chapter 9 of the DC Green Construction Code (DC-GCC), and shall use the ICC G4 as a guide for Commissioning.
Systems to be Commissioned are outlined in Section 611 and Chapter 9 of the DC Green Construction Code (DC-GCC.) This included new systems, relocated systems, and Existing systems serving new spaces or with new performance characteristics or set-points. For example, an existing VAV-box serving reconfigured offices should be included in the commissioning process for DC-GCC.
^New construction includes additions of over 10,000 sf, and all first-time tenant fit-outs, as they are completing the new construction of the building.
*Projects pursuing compliance under an alternative compliance pathway (e.g. LEED, Enterprise Green Communities, ASHRAE 189.1, NGBS/ICC-700) per Section 18.104.22.168 of the DC Building Code, or are subject to the Green Building Act will have specific commissioning requirements per the selected pathway. Please review the requirements of each program.
Approved Commissioning Sampling
Project teams and Commissioning Agents (CXa's) wanting to implement sampling during Commissioning, shall follow the RESNET Sampling Protocol, including for multiple identical systems commissioned within a 30 day period:
- full commissioning of the first seven, if one or more of the first seven record a failure (failed PFC or FPT), Commissioning of every unit until 7 consecutive passes are recorded.
- sampling one out of every 7, after the first 7, if the first seven do not record a failure is allowed.
- if one PFC or FPT records a failure within a sampling set, an additional two from the 7-set shall be commissioned. If one of these two record a failure, the remaining 4 in the set shall be commissioned. Continue Commissioning all systems at random until seven consecutive passes are recorded is required before Sampling is allowed to be implemented again.
- when Sampling, the chosen system to Commission shall be chosen at random out of the sampling set by the CXa.
Any Sampling rate proposed and/or implemented shall be clearly outlined and recorded on all CX plans and Reports.
Elements of a Preliminary Commissioning Report
Per GCC Section 611, a preliminary commissioning report must include the following:
- Completed Pre-Functional Checklist
- FPT- Results of Functional Performance Testing
- Issues Log- Disposition of all deficiencies including details of corrective measures used. Include issues resolved, issues outstanding, and deferred tests.
Certification of Compliance- Compliance with DC Energy Conservation Code C403 Building Mechanical System and C404 Service Water Heating sections.

Per DC Energy Conservation Code (ECC) C303.1.3 & R303.1.3, the U-factor and SHGC of fenestration products shall be labeled and certified in accordance with NFRC. Fenestration is a defined term in the ECC and includes skylights, vertical windows, curtain walls, and storefront glazing. Products lacking such certification may use default value tables. Additional information on labels and certificate labels can be found at www.nfrc.org.
The technical requirements of the rating, certification and labeling program of NFRC 100 are set forth in the NFRC 700 Product Certification Program, and NFRC 705 Component Modeling Approach Product Certification Program.

Building Leakage and Duct Leakage Testing
The 2017 residential provisions of the DC Energy Conservation Code (ECC)* require applicable projects to conduct building leakage and duct leakage testing. The Residential ECC covers all single family homes and townhouses, as well as multifamily buildings 3 stories or less above grade. Blower door and duct leakage testing must be performed by an approved third party energy testing professional, as defined in this manual..
Green Inspection Scheduler
GREEN Code Inspections
Inspections associated with the DC Green Code may be performed by the DCRA Personnel even if a third party inspection agency is conducting remaining inspections. The Green Building Division realizes the time pressures associated with many of these jobs, and is striving to provide very quick inspection scheduling -- next day scheduling is often available. Note that in certain circumstances other inspections may be scheduled here also, though in general they will be scheduled through the IVR telephone system.
