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.

• 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?
• No, including all elements in the model is not necessary. We should focus on the major details of constructions, for example structural elements like floors, columns, foundations, framings. Including too many details will affect the interpretation of the simulation.

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?
• Linking model elements to project schedule helps to understand work flow, identify potential critical paths in construction, improve coordination, and manage resources availability and materials delivery.

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?

Designers can improve their designs by using the information to evaluate different material use and building options optimize cost saving, and to ensure the project stay within budgets.
