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?
You cannot guarantee that the completed building will match the performance predicted in its day-to-day operations since the operation analysis is an average of the worst and best-case energy consumption scenarios. However, suppose the stakeholders edit the parameters of the building, for instance, the days and hours of operation, to match their exact case. In that case, the analysis will be more accurate and closer to matching the performance on a regular day-by-day basis.
When choosing settings for each of the building performance factors, should you always choose the setting that gives the absolute lowest predicted energy use?
Although choosing the lowest parameters for the building performance factors might lower the total cost and energy consumption, it might not always be the most suitable, especially when considering upfront costs. For instance, solar panels require a large endowment in the beginning, and this cost could be multiplied depending on the PV coverage percentage, which might not be economically feasible for some stakeholders. It is also important to consider the climate and temperature of the building’s site in this situation. Even though relying on sunlight and airflow might be the most sustainable, some areas, such as those with hot and humid climates, depend on higher HVAC controls to accommodate comfort levels in comparison to those with milder and Mediterranean climates. Lastly, choosing the lowest predicted setting might not allow for easy manipulation in the future, and it is important to implement features that are easy to change and adapt and needed with the changing and developing times.
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?
Conducting shorter simulations provides a targeted approach to optimizing material and labor flow in construction. The short simulations also allow the construction managers to see the order of the procedure and allow them to fix any conflicts or confusion that may arise during the simulation, such as an incorrect order of material placement, task confusion within different construction sectors such as electricity or plumbing, or an early or late start time. A short simulation also serves as a quality control measure before the structure is built and permits the stakeholders to change any material, order, or procedure before they begin. This proactive approach enhances overall efficiency and minimizes the likelihood of costly errors during the construction process.
