Class summary
In this session, we’ll examine how to prepare and capitalize on your Revit
software model to get the best results. We’ll start by reviewing what an energy
model needs from Revit software to maximize the results. Next, you’ll discover
how to create an energy model in Revit and review the simulation results. After
learning what the predicted energy costs are going to be, we’ll take a peek into
Insight 360 software to perform a heating and cooling load analysis, and we’ll
wrap up by reviewing the lighting and solar potential analysis tools. It’s all about
taking the power of Building Information Modeling (BIM) to the next level, and
using it to produce a sustainable design. This session features Revit, Insight 360
and Green Building Studio.

Powering BIM—Capitalizing
on Revit for Building Energy
Modeling - Introduction

Why?
Gain better understanding of
design on environment and
resources
Industry can leverage design
models for more than
construction documentation
Communicate ROI on different
strategies while minimizing
design costs

Before the Project Setup
What type of energy modeling and what details are
required?
What are the Federal/State/Local governing
agency requirements the design must meet?
What are the expected Energy Use Intensity
(EUI) metrics?

EUI Metrics
Examples of EUI measured using the design model from Insight 360:

Before the Project Setup
For Heating/Cooling Load requirements, can
you compare systems to determine Annual
Energy Costs?
Can you examine Potential Energy Savings
based on structure design/conditioning
systems/passive equipment?
Are there opportunities for Water/Sustainable
Material reuse?

Conceptual Versus Building Element Analysis
Conceptual Masses and Shapes
Use in preliminary stages
Easy to orient to site
Can add mass floors
Best for overall studies

Conceptual Versus Building Element Analysis
Building Element Modeling
Use architectural bounding elements
(Walls, openings, floors, ceilings,
roofs)
Use generic types – don’t over model!
Model accurately – avoid gaps
Avoid extra features – column
enclosures, bumps, cutouts, reveals,

Discovering Insight 360
Selecting a report toggles a more detailed
view
As a report is selected, the 3D model view
updates to reflect details from the report
