New Users: Creating your first Full House Audit and Energy Savings Model

Labels:

Creating Full House Audits requires a minimum set of data to enable the Energy Savings Modeling.

Once you have entered in Client Information, and the client is approved for an Audit, try creating a full house audit by completing the data on the following pages:

Building Information

  • Select Weather data
  • House dimensions ( For example, if a house had a basement the entry would be 44x24x8 = floor 1 , then a new row with 44x24x8= floor 2)
  • Optional = Building information / general information


Heating/ Cooling

  • Add existing heating system (required fields = system type, usage ratio = 100%)
  • Add existing cooling system (+ sign on the bottom right adds new systems, usage ratio, system age are required)

Zonal Distribution
Quantity - If using Duct work, enter in the total linear ft of supply duct.

  • Assign an existing system to the Distribution.

Lighting

  • An easy way to model this screen is to enter "Whole house Lighting"
  • Choose the existing fixture (ex: Incandescent 50 watt)
  • The rest of the screen populates for you


Hot Water Heater Direct Install

  • Choose a measure, like a shower head and enter quantity and price
  • "Choose this row to add a new entry" to add the aerators (or next measure)


Hot water tank

  • Size, Temperature, Usage ratio and pipe length


Attic

  • Length , width, existing R value in the attic, framing = unfloored


Wall

Example of 2 wall entries, one for the north and south, one for the east and west:

  • Length x width , quantity of walls defined (2), orientation (east), exsiting R value of wall
  • Length x width , quantity of walls defined (2), orientation (west), existing R value of wall
  • (On each wall, click "window and doors" and create a window type and place the windows on the wall)


Basement
First entry - Basement floor:
The length and width of the floor below (section type = cantilever floor, framing hardwood floor)

Second entry - Conditioned walls
The perimeter of the walls x the wall height (section type = conditioned, heated basement walls)

Air Infiltration
If you choose the fan pressure and house pressure, the CFM will auto calculate. Then enter the target.

Trying to model a Small Multi-family home using Single family modeling? Select "Single family rental" rather than "Owner occupied Single family" This should allow you to model the home as a single family instead of a multi-family home.
