ASHRAE 90.1‐2010 & SB‐10 – SECTION 5.5 – PRESCRIPTIVE ENVELOPE OPTION Detailed Form 5.5‐1

Overall Building Envelope Design Requirements The building design must comply with the following general requirements. If any of these requirements are not met, the prescriptive

path cannot be pursued. Consider the building envelope trade‐off compliance or the Energy Cost Budget Method Described in

Chapter 11 of ASHRAE 90.1‐2010:

Identify SB‐10 Table used for maximum U‐Factors or minimum RSI‐Values : _______________

Gross Wall Area: m²

Vertical Fenestration Area: m²

Vertical fenestration area is less than 40% of the gross wall area.

□ YES

Gross Roof Area: m²

Skylight Area: m²

Total skylight area does not exceed 5% of the gross roof area.

□ YES

Where the main entrance door is located on the south orientation and south wall area is

larger than west wall area and also larger than east wall area, the total east vertical

fenestration area is less than south vertical fenestration area and total west vertical

fenestration area is less than south vertical fenestration area.

South vertical fenestration area: m²

East vertical fenestration area: m²

West vertical fenestration area: m²

Please specify if any exception is used: ________________________

□ YES □ N/A

If electric space heating is used, Table SB5.5‐7 has been used regardless of climatic location. □ YES □ N/A

For Climate Zone 5, minimum skylight fenestration area conforms to the requirements of

ASHRAE 90.1‐2010 5.5.4.2.3.

□ YES □ N/A

Complete the table on Form 5.5‐2 to show compliance for all envelope components. Attach as many copies of this form as required

to ensure that all envelope components are represented.

For all opaque surfaces, compliance must be demonstrated by meeting either:

1. The minimum R‐values of insulation added in framing cavities and continuous insulation as specified in Tables SB5.5‐5 to

SB5.5‐7.

2. The maximum U‐factor, C‐factor, or F‐factor for the entire assembly as specified in Tables SB5.5‐5 to SB5.5‐7. U‐factor is to be

determined from tables in Appendix A of ASHRAE 90.1‐2010 or through calculation methods described in ASHRAE 90.1‐2010

Appendix Section A9.

For all fenestration products, compliance with U‐factors and SHGC must be determined for the overall fenestration product.

1. Fenestration shall have a U‐factor and SHGC not greater than those specified in SB‐10 Tables SB5.5‐5 to SB5.5‐7.

2. U‐factor to be determined through CSA or NFRC ratings or by using ASHRAE 90.1‐2010 Appendix A default values.

Compliance Result

The design detailed in the above referenced plans complies with the mandatory requirements of the ASHRAE 90.1-2010 Standard and

the additional requirements of Supplementary Standard SB-10. The calculated proposed building energy cost (design energy cost), CO2

emissions and peak electric demand do not exceed the calculated reference building energy cost (energy cost budget) CO2 emissions

and peak electric demand. Therefore, this design DOES COMPLY with the ASHRAE 90.1-2010 ECB compliance methodology and the

additional requirements of Supplementary Standard SB-10.

The information submitted above is accurate to the best of my knowledge.

Signature: Name/Title:

Notes: (1) Verify with building official whether full modelling report is required to be submitted.

(2) Explain major energy saving features utilized to achieve modelled savings.

appropriate for this project.

d. Continue through each item on the tab. If the item is compliant, check the “Compliant” box.

o As each “Compliant” box is checked the red bars to the right of the sheet will turn green. This will help you identify any items you have inadvertently missed.

Notes:

a. Complete every compliance tab listed in the spreadsheet. Each will be clearly named identifying the compliance path you have identified for each part for this project.

For example “Envelope – Detailed TOP” is the tab for Part 3 – Building Envelope - Detailed trade off path (TOP).

b. Each tab starts with a Section called “General”

o This section provides space for up to 500 words for you to identify key remarks related to this part – elements that were pre-existing that could not be controlled

for, for example, and decisions that you have taken that you believe your building inspection officials need to know.

c. Provide a response to every item listed on the appropriate tab for each of the compliance path(s) selected.

o In some cases you have the option to select “N/A” – Not Applicable.

o In such cases there will be an area (called “Explanation”) for you to provide an explanation of why the item does not apply. Provide a written explanation.

3) In the “Compliance Documents Checklist” tab, please identify for the project which paths are being followed for prescriptive and trade off for Parts 3, 4, 5 and 6, and

performance path for Part 8 of NECB 2011.
