This chapter specifies for each building descriptor the rules that apply to the proposed design and to the baseline building. Building descriptors are grouped under objects or building components. A wall or exterior surface (an object) would have multiple building descriptors dealing with its geometry, thermal performance, etc. Each building descriptor contains the following pieces of information.
| Building Descriptor Title | |
| Applicability | Information on when the building descriptor applies to the proposed design |
|---|---|
| Definition | A definition for the building descriptor |
| Units | The units that are used to prescribe the building descriptor |
| Input Restrictions | Any restrictions on information that may be entered for the proposed desig |
| Baseline Rules | How the building descriptor applies to the baseline building |
