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?

A: No. The settings for building performance factors are based on many factors. For example, the function of the building will determine the opening time of the building, which will have a certain impact on the energy consumption of the building. If we only choose the lowest energy use, then the opening time of the model will not match the fact. The results of energy consumption analysis will have no reference value. If the actual opening time of the building adopts the plan that consumes the least energy, the building will not be able to perform its own functions.

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: Generally speaking, 4D simulation of a whole building is a long process and is not very detailed. Shorter simulation can be very specific and clarify some construction details. For example, we will only mention that the construction time of the concrete column is two weeks in a 4D simulation for an entire project, and we will not clarify the corresponding time for the specific construction process. If we only need to focus on the specific process in these two weeks during a 4D simulation, we will clarify the time of the scaffolding construction, the time of the concrete pouring mold construction, the time of concrete pouring and the time of curing the concrete column.

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

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

A: Permanent architectural and structural building components & construction machinery and other engineering equipment should be included in a 4D simulation. We don’t need to include all the elements. Some elements, such as trees, people, original roads, etc., do not need to be mentioned in the 4D simulation. All elements in the 4D simulation should be related to the construction schedule. These elements should appear or disappear during construction.

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?
