cove.tool has pre-created templates for 8 building types but also allows advanced users to create custom template that fits the project's specific conditions. Users also have the ability to validate any value assumptions with the cove.tool technical team using the Live Chat Box feature, found on the bottom left hand corner of the web app.

First step is selecting an existing building type template. The practical knowledge of knowing one’s building use type is important to recognize the particularities of type specific energy consumption and expenditure. The key parameters which impacts the Energy Use Intensity (EUI) include Mechanical Ventilation Supply Air Flow Rate (CFM), Lighting Power Density (LPD), Equipment Power Density (EPD), Occupancy Schedule, HVAC System Type, Envelope Properties, Domestic Hot Water Demand, Air Changes per Hour (ACH), etc. This article discusses the fundamentally different engineering input values to create K-12 School Template.

Step 1:

Set the ‘Project Name’ as intended building use template and select the ‘Building Type’ that closely resembles to the intended use. Also, check the box below the Energy Code to make the project a template for firmwide use(highlighted in red in the image below). The energy code selected for the K-12 School is ASHRAE 2016. The Building type Education closely resembles the occupancy, equipment load and ACH required for K-12 School building.

Learning more about each existing system and how they are identified/ differentiated is key to creating a new template. After selecting a building type, complete your project and geometry pages. The next key step occurs in the baseline energy tab.

Step 2:

Modify the Building Type name in 'Baseline Energy' page so that it'll be easier to understand that the project has been converted to custom template.

Step 3:

Adjust the Mechanical Ventilation Supply Air Flow Rate (CFM) accordingly. The supply air flow rate for K-12 School is 10 cfm/person (people outdoor air rate) and 0.12 cfm/ft2 (area outdoor air rate) based on ASHRAE 62.1 Table

Step 4:

Adjust the Lighting Power Density according to the use type. The Lighting Power Density (LPD) maximum allowable value (0.81 W/ft2) is taken from ASHRAE 90.1 version 2016 for K-12 School.

Step 5:

Adjust the Equipment Power Density (EPD) according to the use type. The Equipment Power Density (EPD) acceptable value (0.5 W/ft2) is taken from ASHRAE 90.1 User’s Manual Version 2013.

Step 6:

Edit the 2030 building type to match with the modeled building and hit 'recalculate' to get accurate 2030 baseline EUI value.

Step 7:

Adjust other engineering inputs such as occupancy schedules, occupant density, heating/cooling set-points etc. according to the building type and hit 'recalculate' to include that in analysis. For this example, the remaining engineering inputs are kept identical for K-12 School and education. Other inputs can be edited via engineering inputs tab to make the customized template.

The created template can be used by other team member by using the "copy" button.

Also, when the Step 2 is followed, cove.tool will automatically update all name tags in the report for the users.

Happy modeling!
