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?

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

You shouldn't always choose the setting that gives the lowest predicted energy use since that design may be extremely expensive or may not meet certain constraints on the building such as space, etc. You should discuss with the parties involved what is the best design option that minimizes the energy use of the building and focus the design on that option.

How can you use Insight feedback to make design choices regarding materials, lightning, 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?

A simulation that focuses on a 1 to 2 week period can be useful in situations where elements need to be demolished and constructed in a certain location of a project. Narrowing the scope of the simulation will allow this specific event to be focused on and allow everyone to observe how the demolition and construction process should be implemented.

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?

Model-based quantity takeoffs can provide information about the quantities and costs of certain building elements. If you are using concrete columns, beams, and floors, it is useful to know how many cubic yards are needed and see if a supplier would be able to fulfill such an order. If not, a design using other materials such as steel would probably be more practical.

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

If a design costs too much, engineers can easily change the materials of the structural elements and update the cost of the project. By comparing different alternatives, they can ensure that the system they eventually choose will be the most cost effective.
