Enter values to identify building space types impacting energy use (e.g., offices, conference rooms, assembly areas, data centers, laboratories, food service), their floor area and occupancy details. Available use types correspond to the property types in Energy Star Portfolio Manager, found here:


https://www.energystar.gov/buildings/facility-owners-and-managers/existing-buildings/use-portfolio-manager/identify-your-property-type


Create entries for all of the property use types contained in the building and the associated gross floor area and operational details of the space.  Select the ‘Add Use Type’ button to begin and to add additional entries.


Entries may include space functions and/or building area types.  Use the drop down menus to select existing and original intended use types. 


Gross Floor Area:  Enter the gross floor area of the selected use type.  The percentage of total area of the use type in relation to the Gross Floor Area of the building will be displayed on the Use Type summary screen.  E.g.:


Note: Parking garages and surface parking are not required for audit reporting and do not need to be included as one of the Use Types entered for a building.  Should you choose to add a Parking Use Type, do not include the gross floor area in the rest of the building’s gross floor area.  This approach follows guidance provided by Portfolio Manager in the following documents:


Percentage of Space Conditioned: Enter the percentage of the space that is conditioned. A conditioned space is defined as a space provided with a heat supply capable of maintaining an air temperature of 50°F (10°C) or higher inside a building space, or provided with a cooling supply capable of maintaining an air temperature of 86°F (30°C) or lower inside a building space.

 

Occupants and Use: Enter estimated numbers of occupants and personal computers/laptops that regularly use the selected space, and the hours and weeks that the selected space is used.

 

Elevators and Operations: If elevators and/or operations inputs have been added in the Operations section, return to this screen and select these entries from the pull down menus to associate with the selected Use Type.

 

Plug Loads: Enter a value for the approximate plug loads for each space. This field should include a sum of the miscellaneous electric loads resulting from electric devices not responsible for space heating, cooling, lighting, and water heating. Examples include computers, printers, copiers, desk lighting, vending machines, and refrigerators.

 

Dwelling Units: If Multifamily Housing is selected as the Use Type, fields for the number of dwelling units and the percentage of dwelling units currently occupied will be available.


HVAC and Lighting Type:  Select the Principal HVAC and Lighting Types that serve the Use Type by selecting from the pull down menus that will be automatically populated and displayed here based on Space Functions Served inputs for HVAC Systems entered in the HVAC section, and Lighting Types entered in the and Lighting section.


Note: return to this screen and select these entries from the pull down menus to associate with the selected Use Type to complete this section.


When including inputs for a Parking Use Type that is unconditioned, add an HVAC system with ‘No Heating’ and ‘No Cooling’ as the Heating and Cooling Source, and select this system from the Principal HVAC drop down field in the Use Types section.   


Common and Tenant Area: The selection of Principal HVAC and Lighting Types is required for New York City Energy Efficiency Reports, San Francisco and Berkeley Reports. A percentage of common and tenant areas must also be entered for New York City Energy Efficiency Reports, San Francisco and Berkeley Reports.
