Explore the critical role of door and window schedules in presenting a building's energy efficiency to regulatory agencies, necessary for Title 24 compliance. Delve into how these schedules are constructed, their significance to the Title 24 engineer for energy calculations, and their relevance to contractors during the procurement process.
Key Insights
- The Title 24 page is a crucial document that presents a building's energy efficiency to the regulatory agency, taking into account aspects like heat loss and gain, glazing efficiencies, and solar orientation.
- Door and window schedules are integral to the Title 24 compliance process. These schedules, present for each floor of the building, detail the number, type, and size of openings, aiding the Title 24 engineer in precise energy calculations.
- Beyond assisting in energy calculations, door and window schedules also facilitate the contractor's procurement process, providing detailed specifications about framing, glazing type, and whether windows are tempered or dual glazed.
Note: These materials offer prospective students a preview of how our classes are structured. Students enrolled in this course will receive access to the full set of materials, including video lectures, project-based assignments, and instructor feedback.
Earlier in our review of this project, I showed you the Title 24 page. The Title 24 was one of the first documents that we analyzed. The Title 24 page is where the energy efficiency of the building is presented to the regulatory agency.
This includes information such as the volume of the actual house, solar orientation, heat loss, heat gain, glazing efficiencies, and information such as that. Well, one set of documents that we present to the Title 24 engineer are our door and window schedules. We have a door and window schedule for each floor of the building, and if I zoom in, you can see that all of my doors and windows are numbered.
And up at the top, I have a table which shows the number, the kind of window, the size of the opening, and information that is pertinent for the door and window schedule. So again, this is information that is given by the design team to the Title 24 engineer so that they can do their energy calculations. And similar kinds of information are presented to all floors of the building.
You can see looking at this, again, since our last submission, we had some revision clouds going on. We added more information because the county wanted to know what kind of framing you were going to have around the door and window, what kind of glazing is going on, whether it was tempered or not, whether it was low E dual glazed or not. So again, the door and window schedules are labeled for each door and window in the building.

It's information that helps out not only the Title 24 engineer, but also the contractor when they are running around purchasing the doors and windows for the project. So spend a little bit of time, look at the door and window schedule, and we'll continue on in just a few more minutes.
