Niobrara Electric offers free energy audits to its members. There are two versions of the energy audit and the option of a blower-door test. Please note that the energy audits are not 100% guaranteed. They are a rough calculation of the heatloss in your home or a specific room in your home.
- "Whole House" Audit: This audit is a room by room (entire house) heatloss calculation. Many measurements will be taken (walls, windows, doors, etc.). Many questions will be asked about all different aspects of your home. Following is a list of information that will be needed:
- Window specs - What is the glass type (clear or low emittance)? Are the windows single, double, or triple pane? What material are the frames made from (wood, T.I.M., or metal)? Same information is needed for any sliding glass doors or french doors.
- Door specs - Is the door wood or metal? If the door is wood is it hollow or solid core or is it a panel door? If it is metal does it have a fiberglass, polystyrene, or urethane core? Is there a storm door?
- Exterior walls specs - Is the exterior wall wood framed with sheathing and siding, brick, or other exterior? If they are sheathed is it in gypsum board, asphalt board, bead board, or exterior poly board and what is the insulation value (ex. R-11) and how thick is it?
- Walls below grade (underground): What are they made of and how far do they extend below grade? Is there any insulation and if so, what is the R-value?
- Walls above grade (above ground): What are the walls made of (masonry, block, brick finished, or brick unfinished)? How thick are the walls and is there any insulation? If so, what is the R-value?
- Ceiling specs - Are ceilings under a ventilated attic space or unheated room? If so, what the the r-value of the insulation? Is the ceiling a roof on exposed beams or rafters? If so, are they wood decking, shredded wood planks, or fiber board insulation? Is there additional insulation? Is it a roof/ceiling combination? Is there insulation and if so, what R-value of batts were used?
- Floor specs - Is the floor over an unheated basement, enclosed crawl space, crawl space with closable vents, open crawl space, or garage? What type of floor is it (hardwood or carpeted)? Is there additional insulation? What R-value? How far below grade are basement floors? Are basement floors concrete slab on grade or concrete slab with perimeter warm air duct system? Is there any edge insulation?
- "Warm Room" Audit: This audit is a simplified heatloss calculation used for one or two rooms in a home. We will measure any outside walls in the room(s), along with windows and doors. Many of the questions above will apply to this audit as well.
- Blower-Door Test: A blower-door is used to find drafts and air leaks around your home. It is placed in an open outside doorway and sealed. When it is turned on it will suck the air from your home, also sucking air through loose windows and doors, outlets, or cracks in walls and ceilings. We will be able to walk around your home and feel for drafts and leaks. You will then be able to determine what areas of your home need repaired in order to reduce heatloss. You may choose to have a blower-door test done during an energy audit or, if you would prefer, we can conduct a blower-door test without an energy audit. If you choose to have one done PLEASE make sure any fireplaces are thoroughly cleaned and all flue dampers are closed. If this is not done your home will be filled with ash.
