This tutorial will help you input the fenestration form on CalCERTS known as the CF-2R-ENV-01. Fenestrations are windows, skylights, and doors that are over 50% window.

Navigating To The Fenestration Form
- Login to www.CalCERTS.com.
- Locate your project. Click the icon to open the project. Use this tutorial if you need help finding your project.
- Click on the green hexagon at the top of the page to view CF-2Rs.
- Navigate to the CF-2R-ENV-01 form. If the project is multi-family multi-orientation, select the icon for a unit/lot. If the project is both multi-family or multi-orientation, the Envelope forms will be regarding the entire building, so you'll find the ENV-01 under the Buildings tab.
Once you're on the correct CF-2R page, click the Report Results link corresponding to the Fenestration Installation CF2R-ENV-01 form.
What Is A Fenestration Record?
- A fenestration/glazing record represents the total square footage of glass that has the same SHGC (solar heat gain coefficient), u-factor, and orientation. The SHGC and u-factor are reflection and insulation ratings for the window; the orientation refers to the side of the house the windows are on.
Imagine a four-sided house with only one kind of window. In other words, the SHGC and u-factor is the same. In this case, you'll have four fenestration records because you have four orientations: north, south, east, and west.
If this imaginary house now had one sliding glass door to the backyard (unique u-factor/SHGC), you'd have five fenestration records: one record for the glass door.
To be clear: you will not have one fenestration record for every individual window unless it is a unique window, such as the sliding glass door in the previous example.
In the above example, you would have five fenestration records. These would be the Fenestration Areas, or the sum of their window sizes.
- West GreenWindows: 100 sq ft
- South GreenWindows: 100 sq ft
- East GreenWindows: 150 sq ft
- North GreenWindows: 50 sq ft
- North SlidingDoor: 100 sq ft
- The first page will indicate how many Fenestration records you have according to the CF-1R.
If you're doing a 2013 code year standard project, the number of fenestration records must be indicated.
- A fenestration record form for 2013 will look like the below image.
The 2016 version of a fenestration record pulls most of the information for you from the CF-1R. Typically it just requires you to fill out the manufacturer/brand.
Filling Out Fenestration Records
Be sure to indicate if the window is a skylight or not.
- Tag/ID - The labeling format used in the plans ensures each unique type is used consistently throughout the plan set. It is an identifying name for the record such as Window-1 or Skylight-1. Typically users include the orientation and describe the function. It should correspond with the CF-1R as much as possible.
- Manufacturer / Brand - what company made the windows? This should be on the NFRC sticker.
- Fenestration Area (ft2) - the sum (total) of all windows' glass square footage. Remember: one fenestration record represents all windows of the same SHGC, u-Factor, and orientation.
- Orientation - what side of the building are these windows? You can choose from north, south, west, and east. Choose the best option; indicate any odd angles in the comments.
- Chromogenic? - Is the window tinted or colored?
- U-Factor - The insulating value of the window.
- Source - How was the U-Factor in 6. produced? Where did we get the value from?
- NFRC, also known as the sticker. The sticker is usually in the corner of each window and is placed there after being made. This is the most common and best option.
- Tables 110.6-A and 110.6-B are found in the New Construction Compliance manual. Using known values of the window, you can approximate the u-factor and SHGC values with the table.
- Equations NA 6-1 and NA 6-2 are another set of tables found in the Appendices. These are for custom fenestrations created on-site.
- Area-weighted average worksheet values are produced from the CF-2R-ENV-02.
- SHGC - stands for solar heat gain coefficient. It represents how much heat energy is reflected by the window.
- Source - same description as 7.
- Fenestration Type - a description of the window's functionality such as sliding and panes.
- Exterior Shading Devices (Describe) - indicate any external features of the house that may keep the window shaded, such as an overhang, bug screen, or roll-down blind.
- Comments/Special Features - a place for miscellaneous comments and notes. Use this space to explain any unmentioned features of the windows.
Submitting The Form
- Choose the Responsible Builder/Installer Name, their Company Name, and their Position With Company (optional). This should be a representative of the company that installed the fenestrations, otherwise it should be the project superintendent or the responsible builder.
Click the SUBMIT button to submit the form. If it only saves the form and doesn't submit it, you need to be sure you've filled out all fields, including all drop-down lists.
