My energy surveys began in 2001, designed so homeowners, designers, builders and other energy professionals could send me yearly energy data to be analyzed and compared for free with other households.  Main purposes of my surveys are to:

    1)  Learn what is best and average home energy performance in the Ohio Valley
    2)  Show how to describe and present energy data to allow better comparability and usefulness

I have 2 reports discussing and summarizing Ohio Valley home energy performance 2001  through June 2012.
   Summary (6 pgs)
   Full Report (24 pgs)

These years' surveys are closed but you can click any year to see the data:

Surveys 2010 and after are still open to accept new data.   Click any year to see annual data:

To participate for free in Ohio Valley Household Energy Surveys for years 2010 and after, sum all conventional energy and fuel bought or acquired (even for free, as with firewood) within the calendar year.  Do not include energy bought or acquired in a prior year or received so late in a year that payment is made the next year.  Organize data according to the following format, then send to me by mail or email (  Send each year's data separately, with "SURVEY" + "YEAR" in the subject line, like "SURVEY 2014".  I will notify you when your results are posted at this website.  After that, recheck your participation years periodically to compare your performance with other participants.    



3) Current HOUSE SIZE (Total gross square feet of "conditioned" space, excluding unconditioned garages, porches, basements, etc.  Above basement, "gross area" is measured from the outsides of exterior walls.  For conditioned basements, use "slab area" inside foundation walls.)

4) Approximate HOUSE AGE and YEARS SINCE LAST MAJOR ENERGY UPGRADES.  For example, if house was built 40 years ago but 10 years ago got new windows, more insulation and a new furnace, say "40, 10".   If more than 1 round of upgrades have occurred, give multiple ages.  If house was built 20 years ago and has had no major energy upgrades, just say "20".

5) Average NUMBER OF HOME RESIDENTS.  If a person lived in home for half the year, add "0.5" for that person.

6) HOW MUCH ARE RESIDENTS AT HOME? (see "b" list below for suggested percents of occupancy)

7) INDOOR TEMPERATURE RANGE YEARROUND.  This could be min-max thermostat settings for heating and cooling, including setbacks.  Or it could be what is actually observed as min-max temperatures in all or part of your conditioned space.  For example, in my home, if we're heating with firewood or passive solar, some spaces will be cooler than t-stat setting even when it's warmer than t-stat setting in most of the house.  So our min-max t-stat settings are 67-79 including setbacks, but actual observed min-max annual range throughout our conditioned spaces is 59-82F.

8) List ALL YOUR ENERGIES.  (Electricity, natural gas, LP, wood, oil, pellets, kerosene, as many as you used)

9) HOW MUCH OF EACH ENERGY (for each energy type listed in #8: how many kWh, ccf, gallons, cords [see note "a" below about firewood], pounds, etc., whatever unit you're charged by.)

10) TOTAL PAYMENTS ($ totals for each energy type listed in #8)  If free, say "$0" or "free" next to energy type.

11) ENERGY SUPPLIERS (for each energy type listed in #8).  If firewood from your neighbor or backyard, say exactly that.

12) WATER USAGE, COST & SUPPLIER: (total usage in gallons or ccf, total WATER-ONLY cost in dollars, name of water supplier.  Do not include sewer costs.)

13) ENERGY FEATURES of your house & household (See "c" list below for features keys)

Here's my own 2016 data organized as I prefer submittals to look:

1) Robbins, John
2) Kenton, KY
3) 2100 sf
4) 30, 18, 13 (more insulations, airtightness, passive solar room addition, better daylighting and more efficient electric lights, new solar PV and hot water)
5) 2
6) 95%
7) 59-82F
8) Electricity, firewood
9) 7024 kWh, 1.04 cords
10) $883.36 for electricity, $140 for 7/8 cords firewood + 1/6 cord free from my land
11) Owen Rural Electric, some firewood from a neighbor
12) 39.85 ccf, $527.91, NKY Water District (water cost only)

(a) Firewood
Measure or estimate firewood by volume.  A traditional "cord" of firewood is 128 cubic feet, often stacked 8' x 4' x 4' either 2 rows of 24" long pieces or 3 rows of 16" long pieces.  A standard pickup truckload is usually 1/3 to 7/16 cord (= 0.333 to 0.437 cords).

(b) Help With Estimating % Home Occupancy
99% only for true stay-at-homes!
95% for most "stay-at-home" w/ 1 or 2 outings per week
90% for 4 member urban/suburban home with one 5-day/wk commuter
85% for 3 member urban/suburban home with one 5-day/wk commuter
80% for 2-person households with one 5-day/wk commuter
70% for 2-person households with two 5-day/wk commuters
60% for 2-person households with two 6-day/wk commuters
50% for busiest run-around households

(c) Household Energy Features (list all that apply)

A - Active Solar (heating water and/or air)
B - Bermed Living Space Walls (like finished bsmts and earthbermed homes)
C - No Clothes Dryer and/or very infrequent use, as when a clothesline is most often used
D - No Dishwasher and/or very infrequent use, as when dishes are most often washed & dried without machines
E - More Efficient or Non-Electric Appliances
F -  Mostly Fluorescent & LED Bulbs
G - Superior Windows (R-3 or better overall, very low air leakage < 0.10 cfm/sf)
H - Efficient HVAC System
I -   Income Production at/from home
K - Household Electricity Used For Vehicle Recharging (whether some or all recharging, hybrid or all-electric)  
L -  Energy Efficient or Productive Landscape (summer shade, food, windbreak, waste processing & storage, etc)
M - Net-metering of onsite renewable energy is used to lower reported electricity use in future billing months
Nf - No Furnace
Na- No AC
P -  Passive Solar for Better Daylighting, Winter Heating, Summer Cooling
S -  Superior Insulation Specs (at least 150% of current local code R requirements)
T -   More Airtightness
U -  Underground Roof & Walls
V -  PVs (solar electricity)
W - Home Water Supply, like a well or roof-fed cistern
