Room Templates control the characteristic of enclosed spaces within a building. The characteristics include heating and cooling setpoints, ventilation rates (people-based, area-based, and exhaust), and internal loads (equipment, lighting, and people).

The Room Template page contains four sections. First, the Room Templates Catalog contains the standard default templates available for use. This is also where Personal and Firm templates are saved for access on future projects. Using the filter and search bar, required templates can be easily found. To copy a template from the main catalog to Project Templates, simply click.

Rooms Page Guide. Open in new tab to enlarge.

The second panel is the Project Templates, these are templates available for assignment to the projects rooms. Custom templates can be created here and later saved back to the Personal or Firm catalogs. To see more detail about a specific template, select it via a click and the Template Details panel will appear.

The Template Detail panel contains all the data associated with that template. It enables users the ability to edit all inputs, add or remove internal loads, delete, and save back to the Personal or Firm catalog.

The final section is the Rooms Data Table. Here template assignment to rooms is displayed, and can also be updated. When first starting a model the templates will be assigned based on defaults in the drawing.tool. To assign a new template to any room or group of rooms follow these steps:

  1. Select the rooms to update via the checkboxes

  2. Select the appropriate template from the Project Templates.

  3. Click the assignment button at the top of the Rooms Data Table to complete the assignment.

Parameters assigned via Templates

Space Type Details

  • Name: This is the descriptive title for the template

  • Energy Code: This field describes the energy code associated with the template if any

  • Firm Name: The firm name that created the template, is automatically set when the template is created.

  • Creator: This is the owner of the template, for templates associated with your project you will be the owner, it is automatically assigned.

  • Description: Notes about the template can be updated in this field.

Setpoints

  • Cooling Setpoint [°F (IP) | °C (SI)]: The temperature setpoints for cooling mode. The temperatures are assigned based on a schedule, the highest and lowest values are displayed for reference.

  • Heating Setpoint [°F (IP) | °C (SI)]: The temperature setpoints for heating mode. The temperatures are assigned based on a schedule, the highest and lowest values are displayed for reference.

  • Regularly Occupied: This toggle denotes if the room is considered regular occupied in the calculations.

Air Flow Rates

  • Flow rate per person [CFM/Person (IP) | L/S/Person (SI)]: Outdoor airflow rate per person.

  • Air Flow Rates Area-based [CFM/ft2 (IP) | L/s/m2 (SI)]: Outdoor airflow rate per unit area.

  • Air Flow Rates Exhaust Rate [CFM/ft2 (IP) | L/s/m2 (SI)]: Exhaust rate per unit area

  • Air Flow Rates Infiltration Rate [CFM/ft2 (IP) | L/s/m2 (SI)]: Infiltration is modeled at neutral pressure of 4Pa.

  • Air Flow Rates ACH: Air changes per hour (ACH) is a measure of airflow compared to a space's volume. Comparing the airflow to a space's volume is done to infer the number of times air within that space is replaced.

Internal Loads

  • Electric Gain Name: Electric equipment load name for the selected template

  • Electric Gain Schedule Name: Electric equipment schedule name for the selected template (e.g., 'Office Building Equipment')

  • Electric Equipment Power Density [W/ft2 (IP) | W/m2 (SI)]: Electric equipment load per unit area.

  • Electric Gain Method Toggle: Electric gain can be expressed in watts (W) when this toggle is used. Default is W/ft2 in IP or W/m2 in SI.

  • End-use Subcategory: This field allows a user-defined end-use subcategory, e.g., “Computers”, “Copy Machines”, etc. A new meter for reporting is created for each unique subcategory. If this field is omitted or blank, the equipment will be assigned to the “General” end-use subcategory.

  • Electric Gain Fraction Latent: This field is a percentage number between 0 and 100 and is used to characterize the amount of latent heat given off by electric equipment in a zone.

  • Electric Gain Fraction Radiant: This field is a percentage number between 0 and 100 and is used to characterize the amount of long-wave radiant heat being given off by electric equipment in a zone.

  • Electric Gain Fraction Lost: This field is a percentage number between 0 and 100 and is used to characterize the amount of “lost” heat being given off by electric equipment in a zone.

  • Light Gain Name: Light load name for the selected template.

  • Light Gain Schedule Name: Light schedule name for the selected template (e.g., 'Office Building Lights')

  • Light Power Density [W/ft2 (IP) | W/m2 (SI)]: Light load per unit area.

  • Light Gain Method Toggle: Light gain can be expressed in watts (W) when this toggle is used. Default is W/ft2 in IP or W/m2 in SI.

  • End-use Subcategory: This field allows a user-defined end-use subcategory, e.g., “Task Lights”, “Hall Lights”, etc. A new meter for reporting is created for each unique subcategory. If this field is omitted or blank, the lights will be assigned to the “General” end-use subcategory.

  • Light Fraction Radiant: This field is a percentage number between 0 and 100. It is the fraction of heat from lights that go into the zone as long-wave (thermal) radiation.

  • Light Fraction Visible: This field is a percentage number between 0 and 100. It is the fraction of heat from lights that go into the zone as visible (short-wave) radiation.

  • Light Fraction Return Air: This field is a percentage number between 0 and 100. It is the fraction of the heat from lights that go into the zone return air (i.e., into the zone outlet node).

  • People Gain Name: People load name for the selected template.

  • People Gain Schedule Name: People schedule name for the selected template (e.g., 'Office Building People')

  • People Gain Method Toggle: People gain can be expressed in the total number of people when this toggle is used. Default is ft2/people (IP) or m2/people (SI)

  • Activity Level Name: Activity level name for the template.

  • Sensible Gain per Person [Btu/h/person (IP) | W/person (SI)]: Sensible gain value per person based on the activity of the template.

  • Latent Gain per Person [Btu/h/person (IP) | W/person (SI)]: Latent gain value per person based on the activity of the template.

  • CO2 Generation Rate [Ft3*hr/min*Btu (IP) | L/s*watt (SI)]: This numeric input field specifies carbon dioxide generation rate per person.

  • People Fraction Radiant: This field is a percentage number between 0 and 100 and is used to characterize the type of heat being given off by people in a zone.

  • End-use Subcategory: This field allows a user-defined end-use subcategory, e.g., “Cooking”, “Clothes Drying”, etc. A new meter for reporting is created for each unique subcategory. If this field is omitted or blank, the equipment will be assigned to the “General” end-use subcategory.

  • Gas Gain Fraction Latent: This field is a percentage number between 0 and 100 and is used to characterize the amount of latent heat given off by gas equipment in a zone.
