Seattle Energy Code
Nonresidential & Multifamily Residential Energy Code Forms

(Chapters 11-16, Nonresidential & Multifamily Residential
& RS-29 Annual Energy Analysis)

The Seattle Department of Planning and Development requires that certain forms be completed and submitted with the permit application.-

  Building Envelope Forms (Note that this spreadsheet contains multiple pages.)

- Application: (1) Envelope Summary Form (page ENV-SUM) is not required, but note that the date and project information must be filled out on this form to carry over to the other forms.
(2) Envelope UA Calculations (page ENV-UA) is optional, only necessary if the Target UA/SHGC/VT compliance option is used. (Code reference: Seattle Energy Code, Section 1330. See the Single-Family Residential Energy Code Forms page for projects within the scope of the SRC - Seattle Residential Code.)
(3) Envelope SHGCA Calculations (page ENV-SHGC) is optional, only necessary if the Target UA/SHGC/VT compliance option is used. 
(4) Envelope VTA Calculations (page ENV-VT) is optional, only necessary if the Target UA/SHGC/VT compliance option is used.  (There are no VT requirements for multifamily residential spaces.) 
(5) Building Permit Plans Checklist (page ENV-CHK) is not required, but it is highly recommended that applicants review this and make sure that plans contain all the information listed.  
- Summary: (1) ENV-SUM provides a broad overview of basic information that is needed on the drawings.
(2) ENV-UA provides the first part of an alternate compliance option for projects which do not comply with the prescriptive requirements.  Nonresidential and multifamily residential portions must be calculated separately.  The criteria automatically shifts when one selects the appropriate occupancy group near the top of the worksheet.  Sample entries for completing the form on shown on page 2 of the ENV-CHK worksheet.  In addition, projects must complete the ENV-SHGC and ENV-VT worksheets, as applicable.
(3) ENV-SHGC provides the second part of an alternate compliance option for projects which do not comply with the prescriptive requirements.  Nonresidential and multifamily residential portions must be calculated separately.  The criteria automatically shifts in the ENV-SHGC worksheet when one selects the appropriate occupancy group near the top of the ENV-UA worksheet.  This worksheet must be completed for all nonresidential fenestration, but only for skylights in multifamily residential spaces (as there are no SHGC requirements for vertical fenestration in multifamily residential spaces).   
(4) ENV-VT provides the third part of an alternate compliance option for projects which do not comply with the prescriptive requirements.  Nonresidential and multifamily residential portions must be calculated separately.  The criteria automatically shifts in the ENV-VT worksheet when one selects the appropriate occupancy group near the top of the ENV-UA worksheet.  This worksheet must be completed for nonresidential projects where the fenestration area exceeds 30% of the gross wall area and for certain type of skylights, but not for other projects (as there are no VT requirements for other nonresidential spaces or for multifamily residential spaces).   
(5) ENV-CHK provides a detailed list, on a section-by-section basis, of what information needs to be on the plans to show compliance with the Energy Code. Note that having this information in the specifications is not adequate This information must be on the plans, as DPD does not approve specifications.  Page 2 contains sample entries for completing the ENV-UA worksheet above. 

  Mechanical Forms (Note that this spreadsheet contains multiple pages.)

- Application: (1) Mechanical Summary Form (page MECH-SUM1) is not required, but note that the date and project information must be filled out on this form to carry over to the other forms.
(2) Mechanical Summary Form (page MECH-SUM2) is not required
(3) Mechanical - Complex Systems Checklist (page MECH-COMP) is not required, but it is highly recommended that applicants review this and make sure that plans contain all the information listed. 
(4) Mechanical - Economizer Checklist (page MECH-ECO) is not required, but it is highly recommended that applicants review this and make sure that plans contain all the information listed. 
(5) Electric Motors (page MECH-MOT) is not required, but it is highly recommended that applicants review this and make sure that plans contain all the information listed.
(6) Mechanical Permit Plans Checklist (page MECH-CHK) is not required, but it is highly recommended that applicants review this and make sure that plans contain all the information listed.   
- Summary: (1) MECH-SUM1 only includes the headings to complete other forms, and provides a broad overview of basic information that is needed on the drawings.
(2) MECH-SUM2 is a second version of MECH-SUM1.
(4) MECH-COMP provides a detailed list, on a section-by-section basis, of what information needs to be on the plans to show compliance with the Energy Code provisions for complex systems.  See the MECH-CHK worksheet for information necessary for the mandatory provisions. Note that having this information in the specifications is not adequate. This information must be on the plans, as DPD does not approve specifications. 
(5) MECH-MOT provides a broad overview of basic information that is needed on the drawings.
(6) MECH-CHK provides a detailed list, on a section-by-section basis, of what information needs to be on the plans to show compliance with the Energy Code for all sections other than the complex systems sections. Note that having this information in the specifications is not adequate. This information must be on the plans, as DPD does not approve specifications.

  Lighting Forms (Note that this spreadsheet contains multiple pages.)

- Application: (1) Summary Form (page PRJ-SUM) is not required, but note that the date and project information must be filled out on this form to carry over to the other forms.
(2) Interior Lighting Summary Form (page LTG-INT) is required for all building permit applications (Allowed Wattage portion only) and for all electrical permit applications with interior lighting (all portions, Allowed and Proposed).
(3) Exterior Lighting Summary Form (page LTG-EXT) is required for all building permit applications (Allowed Wattage portion only) and for all electrical permit applications with exterior lighting (all portions, Allowed and Proposed).
(4) Lighting Power Allowance Adjustments Form (page LTG-LPA) is not required.
(5) Lighting Permit Plans Checklist (page LTG-CHK) is not required, but it is highly recommended that applicants review this and make sure that plans contain all the information listed where plans are required. Where plans are not required, these items must be done for electrical inspector review in the field.
- Summary: (1) ENV-PRJ only includes the headings to complete other forms.
(2) LTG-INT provides calculation form for interior lighting and for parking garage lighting.
(3) LTG-EXT provides calculation form for exterior lighting.  The criteria automatically shifts when one selects the exterior lighting zone near the top of the worksheet.
(4) LTG-LPA provides a form to do the ceiling height adjustment where allowed.
(5) LTG-CHK provides a detailed list, on a section-by-section basis, of what information needs to be on the plans to show compliance with the Energy Code. Note that having this information in the specifications is not adequate. Where plans are required, this information must be on the plans as DPD does not approve specifications. Where plans are not required, these items must be done for electrical inspector review in the field.

 

RS-29, ANNUAL ENERGY ANALYSIS

RS-29, Handout on Requirements in the 2009 Seattle Energy Code

- Application: Informative.
- Summary: Reference Standard 29 (RS-29) in the 2009 Washington State Energy Code (WSEC) has been completely rewritten from the 2006 WSEC.  RS-29 is now a modified version of Appendix G from ASHRAE/IESNA Standard 90.1-2007.  The 2009 Seattle Energy Code has also amended sections of the 2009 WSEC.  This handout highlights some of the key changes. 

Energy Enduse Summary Form

- Application: Only necessary if the RS-29 Annual Energy Analysis compliance option is used.
- Summary: This form shows the energy consumption by enduse for both the Baseline Building and the Proposed Design as well as the differences between the two, to allow a means for evaluating the energy analysis. 
     [Note that the 2009 Energy Code, Section 1.2, requires that the Proposed Design have a calculated annual energy consumption that is at least 5% less than the Baseline Building.]

Design Parameter Comparison Form

- Application: Only necessary if the RS-29 Annual Energy Analysis compliance option is used.
- Summary: This form shows a comparison of key input and output assumptions for both the Baseline Building and the Proposed Design, to allow a means for evaluating the energy analysis.

 

Single-Family Residential Energy Code forms
Summary: Contains title, description, and option to download electronic forms used for the single-family residential portions of the Energy Code (Chapters 1-10).  Also, includes Heating Equipment Sizing Form to be used for multifamily residential.
