Please share your comments on 3 of the following Points to Ponder questions. (Choose 3 of the questions below.)

Can you guarantee that the completed building will match the performance predicted by the analysis in its day-to-day operations?

  • Why or why not?

There is no guarantee that the completed building will line up with the predictions. There are several design factors that are susceptible to human error and day-to-day changes. Infiltration would be one example.

When choosing settings for each of the building performance factors, should you always choose the setting that gives the absolute lowest predicted energy use?

There were several factors where I made the settings different than what would give the lowest energy use. For example, plug load efficiency should be selected given that it’s an office that uses lots of electrical devices and will have a high energy load.

How can you use Insight feedback to make design choices regarding materials, lighting, PV, etc.?

Materials can make a big impact on predicted energy use, especially with what materials are used for the walls and roofs. Knowing how the materials affect energy use can inform the decisions on which materials to use

4D simulations are often used to show the construction sequence for an entire project, but shorter simulations that focus on a specific period of time are also useful.

  • Can you provide examples of how a simulation that focuses on a 1 or 2 week period could be useful for planning?

What level of detail should be included in a 4D simulation?

  • Should you include all of the elements in the building model?

How can the feedback shown in a 4D simulation help you to optimize the project schedule?

  • What are the main benefits of linking model elements to the project schedule?

How can model-based quantity takeoff improve the design process?

How can designers improve their designs using the information provided by preliminary estimates of the cost of building their design ideas?
