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?

No, it is not possible to guarantee the completed building will match the performance predicted by the analysis because there are many things that can be different in actuality. Day-to-day operations may differ than originally intended, for example. Markets can change drastically, so the intended use of a building can change. Even minor changes in the amount of people, appliances, or time the building is used can result in difference performance. Models cannot always take into account these variances.

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?

A 1 to 2 week 4D simulation showing a construction sequence can be important during different parts of the construction process. Laying the foundation, for example, may be an important period that may require more in-depth planning. Shorter simulations can also allow for a more precise scheduling of projects in relation to other projects in the vicinity that may affect its construction.

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

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

The level of detail that should be included in a 4D simulation depends on who the target of the simulation is. A structural engineer may need a 4D simulation with a finer level of detail than a 4D simulation required for a community meeting would need. It all depends on the target audience and who information is being communicated to.

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?

Preliminary estimates of building costs can be used to improve designs to ensure designs are viable and in line with the expectations of clients. Many times, these expectations are around efficiency and financial feasibility. Therefore, model-based estimating can be used to make changes that can drive down building costs to ensure designs are in line with client demands.
