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?

• No because the performance predicted by the analysis is constrainted to just however much data it is fed. However, in the day to day operation of a building, different factors come into play that a simulation cannot simulate.

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.?

Insight provides insight into the energy demans of the building and the minimum and maximum requirements for different factors such as insulation or how much lighting a building will need.

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?

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?

Designers can better work within their constraints and optimize what they have rather than going over budget and having to make last minute design cuts.
