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?
  • The building energy use will ultimately depend on its tenants and their habits. Having an estimate generated by Revit will provide great information to the contractor and clients, but the performance will greatly depend on the energy conservation habits by the tenants (leaving windows open, turning off lights when they are not in use, etc.

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

Not necessarily. The option with the lowest energy use might help saving money on the energy bills, but the energy efficient equipment / building design might skyrocket construction prices, making the investment not worthwhile.

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

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?

Having preliminary cost estimates might convince contractors/architects to modify their design/material choices to reduce project cost before construction begins. Having a preliminary estimate gives several stakeholders the ability to analyze costs and make decisions.
