Work with material thermal properties for analysis

00:04

Key variables in the outcome of a systems analysis are

00:07

the method or mode used to generate the energy model.

00:10

The materials assigned and the material thermal properties.

00:15

When creating an energy model from a linked architectural model,

00:19

the available material choices and material thermal properties will

00:23

depend upon the way the architectural model has been created

00:27

and the material thermal property choices made

00:30

in the advanced energy settings of rev.

00:34

In this project,

00:35

we will recap on the available options for

00:37

generating the energy model and review the available

00:40

options for material thermal property selection along with

00:44

the order of priority for application during analysis,

00:49

ensure the view is set to H VAC floor plans, 01

00:54

H VAC plan.

00:57

Let's first review the mode options in the energy settings.

01:04

The energy model can be created by either using

01:07

the building elements from the detailed architectural model,

01:11

conceptual masses.

01:12

If they've been used to define the building envelope of the architectural model

01:17

or from rooms or spaces,

01:21

whichever method is used,

01:22

material thermal properties will be applied to the resulting energy model

01:27

and can be controlled to affect the outcome of the analysis

01:32

set. The mode option to use conceptual masses and building elements.

01:36

Then select the edit button under advanced and other options

01:44

in the material, thermal property section. Select edit against conceptual types

01:51

for mass model elements such as walls, floors and roofs.

01:55

The user can determine the construction material that

01:58

will be used as the basis for analysis

02:02

for each mass modeled element type. The construction material can be changed

02:07

from the dropdown menu against mass exterior wall. Review the available options

02:17

then select OK to close the window,

02:22

select the small gray button against schematic types.

02:28

The schematic type shown here under the category column provide

02:33

the option to override the materials previously shown in conceptual types

02:39

where there is a check in the override column.

02:41

This is the material that will be used in the analysis for that category.

02:46

As with conceptual types, the materials for each category can be changed

02:52

from the dropdown menu against exterior walls, review the available options,

03:00

then select OK to close the window.

03:04

Finally, there is an option to place a check against detailed elements

03:09

where the linked architectural model contains

03:12

physically modeled elements such as walls,

03:14

floors, doors, windows and roofs

03:17

and those elements have material properties defined

03:20

when this option is selected,

03:23

these material thermal properties will take priority over

03:27

conceptual types and schematic types for the analysis.

03:32

Regardless of how the energy model was created,

03:35

all three options can be set with the order of priority being detailed elements.

03:41

Schematic types, then conceptual types,

03:46

setting the mode to the recommended use,

03:49

conceptual masses and building elements will cater for both

03:53

types of elements in the linked architectural model,

03:56

conceptual masses and physical building elements

04:01

use the material thermal property section of the energy settings to suit the

04:06

type of elements used in the architectural model and the level of model development

04:11

as model development progresses,

04:13

changes to the material thermal properties

04:16

will provide ongoing and comparative analysis results

04:20

that can be used to drive the design decisions in your project.
