install programmable thermostat

A programmable or "set-back" thermostat saves energy by reducing the temperature difference between indoors and outdoors -- and thereby the rate of heat transfer to the outdoors -- while you're away from home or tucked in bed.  If you program it to bring the temperature back to a comfortable level before you get home or wake up, you may not even notice that it was changed!  Homes that are built of wood and drywall will save more energy with a programmable thermostat than homes that have a lot of concrete, tile, or stone indoors, because dense materials don't change temperature as rapidly as light ones.

We recommend programmable thermostats even for people who are home all the time and like to keep the temperature constant, because when they sell their homes, the next owners will probably not be home all the time.

1977 bi-level, Emporia

We found high levels of carbon monoxide from both the water heater and furnace, plus the water heater was spilling its exhaust into the laundry room.  This was an immediate safety hazard.

The house was also found to be too airtight for two people, let alone the number who could live in its 6 bedrooms.  We recommended a ventilation system.

1998 ranch home, Emporia

We discovered a patch of black mold in the basement of this house, and we conferred with the owner before running the blower door test, since the blower has the potential to spread the mold.  We ultimately decided to go ahead with the test because there were no visible air leaks on the far side of the mold (and the lack of ventilation in this location likely contributed to mold growth, since mold likes stagnant air), so the benefits of the test outweighed the risks on this occasion.

1910 ranch home, Emporia

This house was in relatively poor condition compared to what we usually see.  There were numerous significant problems, ranging from fire hazards (cumbustible insulation in the electrical boxes -- see photo) to mold hazards (rotting floor boards in the mechanical closet -- see photo), to toxic gas (water heater producing more than 63x the safe amount of carbon monoxide), to biological hazards (squirrels living in the attic).

1959 ranch home, Lawrence

This small, two-bedroom house was very well built -- except for the parts that weren't.  The windows in the lofted bedrooms were particularly leaky.  The water heater and furnace were all the way at one end of the house, on an exterior wall.  The plumbing and ducts ran through the unheated, vented crawl space.  In the course of our inspection we also found the dryer vent entirely clogged with lint.

1912 Old Style house, Emporia

The owners of this house had only recently moved in, after renting it to others.  The tenants had used the thermostat very frugally so that the heating bills were unusually low and the computer model could not be made to match accurately.

We found a gas leak at the end of an old disconnected pipe where an appliance had been.  We recommended removing and recycling the pipe, capping off the junction.

1997 conventional, Council Grove

This house was unoccupied for most of the year, so its utility bills were extremely low, eliminating the cost-effectiveness of any efficiency improvements.  We were able to make recommendations for improvements, but our calculations of cost effectiveness were thrown off by the low bills.

1958 ranch home, Emporia

This rental home had a humid basement and no ventilation in the bathrooms or kitchen, and it was 63% too airtight to meet guidelines for air quality.  We recommended adding a heat-recovery ventilator to improve the air quality and reduce the possibility of mold growth.

1994 ranch, Gridley

This home was built quite air-tight -- 43% tighter than recommended -- and was having significant moisture problems both upstairs, where the walls would sweat in wintertime and grow mildew in summertime, and in the crawl space where water was standing.  We recommended improving drainage away from the foudation, adding a vapor barrier to the crawl space floor, and adding a heat-recovery ventilator and a heat pump water heater.

public housing, Strong City

We were asked to evaluate the public housing in Strong City for their 5-year report to HUD.  They elected to have us audit only one unit (a row house) rather than all of the units.  The unit we inspected was in excellent condition.

We found high carbon monoxide levels when the water heater started up and advised the landlords to install CO detectors in all units for the safety of the tenants.

1985 Conventional, Emporia

This was quite a large house, but built recently and well so that it was performing quite well.  However, they had humidity issues in the finished basement which appeared to be due to poor air circulation.  We recommended balancing the ducts and installing a larger dehumidifier.

One of the main recommendations we were able to make was to remove the south-facing skylights.  Skylights can be very nice, but when exposed to the full summer sun, they let in a lot of heat!

Notable air leaks included the whole house fan, recessed ("can") lights, and the basement windows.
