Nomenclature
The review checks included in this section are organized into the following groups:
SG checks verify compliance with the general simulation requirements such as that an approved simulation program was used to model baseline/budget and proposed design, that project’s climate zone was established correctly, that simulation results used to establish compliance outcome reflect submitted simulation reports, and that the number of unmet load hours does not exceed the specified limit. In addition, SG checks verify that the total simulated energy use intensity and energy intensities of individual end uses including lighting, miscellaneous loads, heating, cooling, fans, pumps, heat rejection, and service water heating are consistent with the selected benchmarks.
UR checks verify that energy cost is established using utility rates from an approved source and are properly modeled.
BE checks verify that the envelope geometry, thermal, and solar properties are established and modeled correctly.
Lighting, Interior (LI) and Lighting, Exterior (LE)
LI and LE checks verify that the interior and exterior lighting power and controls are properly established and modeled.
Plug, Process and Other Loads (PPO)
PPO checks verify that the miscellaneous unregulated loads, industrial processes, elevators, regulated refrigeration, motors, and combined heat and power systems are properly established and modeled.
SWH checks verify that service water heating equipment type, efficiency, and controls, that the related auxiliary equipment and hot water demand were established and modeled correctly.
Air-side HVAC Systems (AHVAC) and Water-side HVAC Systems (WHVAC)
AHVAC and WHVAC checks verify heating, cooling, and ventilation system type, capacity, efficiency, and controls, and parameters of the related auxiliary components such as fans, pumps, and heat rejection equipment were established correctly and properly modeled.
RE checks cover renewable electricity and thermal energy generation systems such as photovoltaic (PV) systems.
EC checks address calculations that were completed outside of the simulation tool. The checks are only relevant to projects involving renewable systems or exceptional calculations, respectively.
In addition, checks are designated as applying to the Baseline/Budget Design or Proposed Design.
Budget/Baseline Design (B)B checks confirm that the baseline (budget) design described in the submittal reflects the requirements of the selected compliance path and is modeled as reported.
Proposed Design (P)P checks verify that the parameters of the proposed design reported in the Compliance Form match design documents, comply with applicable 90.1 mandatory requirements, and are appropriately modeled.
Example of the format for distinguishing between 90.1 G3.2 and G3.3 requirements through the Review Checks Section
G3.2 New Construction/Major Alterations
Requirements for 90.1 G3.2 specifically will be included under this heading.
G3.3 Minor Alterations
Requirements for 90.1 G3.3 specifically will be included under this heading.
Each check has CheckID expressed using this nomenclature. For example, BE08-P is check #8 related to building envelope (BE) for the proposed design (P).
Check Group Information
Sections below list the checks included in each check group. The following information is provided for each check:
- Summary of the relevant 90.1 requirements
- Review tips including location of the relevant information in the Compliance Form, steps for completing the check, sampling recommendations for checks that apply to multiple similar systems and components (e.g. HVAC systems), and common mistakes.
- For review checks that involve verifying simulation inputs or outputs, list of the relevant simulation reports of commonly used BEM. The annotated reports are included in the Simulation Reports section of this Manual.
