3.2.2 Baseline Standard

Purpose

Applicability

All Projects

Definition

The purpose for which the COMNET modeling procedure is used:
The modeling rules and procedures for most of the building descriptors are triggered by this choice.

Units

List of COMNET supported purposes

Input Restrictions

Compulsory input

Baseline Rules

The definition of the baseline building is derived from this input, when applicable.

 

Building Type

Applicability

All Projects

Definition

A building type which is used to determine the performance cost Index target.

Units

Choose from the following list:

Multifamily

Healthcare/Hospital

Hotel/Motel

Office

Restaurant

Retail

School

Warehouse

All Others

Input Restrictions

Compulsory input

Baseline Rules

This choice sets the baseline building performance target for the project.

 

Building Area Classification

Applicability

When the whole building area method is used instead of the space-by-space method of classifying activity in the building

Definition

The building type or principal activity. One of two available classification methods for identifying the function of the building or the functions of spaces within the building, which in turn determine energy-related requirements for the baseline building. Appendix B lists the building classifications that are available under the building area method.

Units

List: Choose a building activity from Appendix B or select “Space-by-Space” if the space-by-space method is used.

Input Restrictions

For multi-use buildings, the building may be divided and a different building classification may be assigned to each part. Either the building classification method or the space-by-space classification method must be used, but the two classification methods may not be mixed within a single rating.

Baseline Rules

Same as the proposed design

90.1-2019

Building Type

Applicability

All Projects

Retail

School

Warehouse

Grocery Store

All Others

Input Restrictions

Required input

Baseline Building

Same as proposed. This choice would determine the baseline performance target for the project.

 

Building Classification for Lighting

Applicability

When the building area method is used instead of the space-by-space method of classifying lighting in the building

Definition

The building type or principal activity. One of two available classification methods for identifying the function of the building or the functions of spaces within the building, which in turn determine lighting-related requirements for the baseline building. Table 9 lists the building classifications that are available under the building area method.

Units

List: Choose a building activity from Table 9

Input Restrictions

For multi-use buildings, the building may be divided and a different building classification may be assigned to each part. Either the building area method or the space-by-space method must be used, but the two classification methods may not be mixed for lighting definitions within a single PRM run.
