Module 9 - Points to Ponder

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?

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.

• In the case of skyscrapers, short period simulation is useful for the project because tasks are repeatable. If construction managers simulate a schedule for a certain floor, they can figure out the total duration by multiplying the days for a floor by the number of the floors.

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

• The higher level of detail leads to a more accurate simulation. However, creating a detailed model would be time-consuming. Construction managers need to think about how they can lower the level of detail. For example, instead of modeling all interior elements, replacing them with an element would make the simulation simple.

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

• 4D simulation allows construction managers to understand the site situation on a certain day. From the understanding, they can make the schedule more feasible and find a more optimum choice.

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?
