Prepare and export your model for energy analysis.
Being able to predict a building's
energy performance is a necessary part of designing sustainably. Although Revit doesn't
have an energy modeling application built into it, it does have interoperability with many
applications that have that functionality.
Master It
Explain the steps you need to take to get a Revit model ready for energy
analysis.
Solution
The steps are as follows:
1.
The building has to have walls, floors, and roofs. Those all need to meet and join so
there are no unrealistic gaps in the model.
2.
Make sure each of the regions in the model has a room element inserted into it and the
room element's height is set to the bottom of the floor above.
3.
Under Area And Volume Calculations, turn on Room Volumes.
4.
You're now ready to export the model to gbXML and import that into an energy-analysis
application.
Chapter 10: Working with phasing, Groups,
and design Options
Use the Phasing tools to create, demolish, and propose a new design.
Time is such an
important element to the design process and nearly impossible to capture with traditional
CAD tools. Don't use phasing for construction sequencing (there's a better way). Embrace
phasing for
communication
, not just
illustration
.
Master It
How can you use phasing to communicate your design across a series of key
stages? What kind of project is best suited to phasing?
Solution
From the Manage tab, you can access the settings for phases. You can create
phases for the major stages of work in your project as well as define filters and graphic
overrides to illustrate the overall design approach. Use the Phase and Phase Filter view
properties to customize project views including schedules. Set the Phase Created and
Phase Demolished properties of model elements to adapt to the project phases. Any kind
of project can utilize phasing, but tenant improvement projects benefit the most from the
ability to document existing conditions and demolition.
Understand and utilize groups.
Groups are great for creating collections of both host and
family component geometry. Just remember to apply best practices, and you'll avoid a lot of
common roadblocks. Individual model elements within groups will always appear properly
in schedules, as you'd expect. And creating exceptions in groups allows you to make subtle
changes without creating a new group.
Master It
Why shouldn't you mirror groups?
Solution
Although mirroring works conceptually, it breaks down in implementation.
Just because you can mirror something in Revit Architecture doesn't mean that it can
actually be manufactured that way. And even more confusion can result if the mirrored
object has to be powered, accessed, maintained, and so on in an impossible condition.
