What is the relationship between energy modeling and glazing strategies?

• A. Glazing strategies are evaluated by energy modeling to meet code and sustainability goals.
• B. Energy modeling does not consider glazing.
• C. Energy modeling cannot assess glazing performance.
• D. Glazing decisions should be finalized before any energy modeling.

Answer: (B)

Energy modeling uses the building envelope, including glazing, as a central factor in estimating energy performance. It requires input on glazing properties such as U-factor, solar heat gain coefficient, and visible transmittance, as well as design decisions like window-to-wall ratio, orientation, and shading. By comparing different glazing configurations, the model shows how annual energy use, peak loads, and thermal comfort respond, helping you meet code and sustainability targets. Glazing strategies are evaluated within the model, and the results guide the choice of options that achieve the desired performance. In practice, glazing decisions are iterated with energy modeling, rather than finalized before modeling, so you can optimize the design based on actual performance data.
