Why I Hate My Job

Well not much really.  But let’s be honest, would you have even had interest in reading if the title was “Why I Love My Job”?  So this is basically my year in review of working for Conservation Services Group performing home energy audits and to share a little more about my job that I did not get to share during the panel discussion at the AIA Ohio Valley Region convention in Dayton, OH last week.

So let’s stick with the title and what I do not enjoy about my job.  First, 90+ degree days, it makes for very uncomfortable working conditions as the attic is 100+ degrees.  However that is a condition of the job and is only an issue of comfort.  The hardest, as well as worst part of the job is delivering news to customers as I was reminded of today.  First is the customer that already has decent levels of insulation and based upon calculated paybacks and program goals do not qualify for very attractive incentives for energy efficiency improvements through the utility rebate program that we do work for.  I get a lot of eye rolling, but that is easy to handle, just lots of additional table talk which can add a lot of time to an appointment that only allows 4 hours to inspect, test, generate a report and present it to the customer.  However the absolute hardest part about my job is telling a customer, especially an assisted customer that is getting free work done that cannot have any air sealing or insulation work done until combustion safety issues have been resolved such as back drafting water heaters, or high CO levels.  This can really tug on the heart strings when you are in a home that has little to no insulation and you can see they would greatly benefit from lower utility bills and truly cannot afford to make some of the repairs necessary, yet their income level is not low enough to qualify for weatherization assistance that would actually make these repairs.

Performing QA/QC Inspections

After a little more than six months with Conservation Services Group and 245 home energy audits under my belt, my role is changing a little.  I am now exclusively doing Quality Assurance/Quality Control (QA/QC) inspections for the next couple of months.  I will be following up on the contractors that are performing work for the Columbia Gas of Ohio Home Performance Solutions program to ensure that they are air sealing and insulating the homes properly and to at least the home energy auditors recommended levels.  Also true to the BPI standards, as part of the QA/QC inspection, I am re-performing the worst case draft test to ensure that all of the atmospheric burning equipment is still drafting properly and not back drafting due to the tighter home that was created.

So now I go from performing two home energy audits a day to 4 QA/QC inspections a day.  Let me tell you, it is a lot dirtier of a job than standard audits.  Climbing through freshly installed cellulose insulation looking for ceiling penetrations verifying if any air sealing work was done if the blower door results don’t show what the contractor claimed or they did not meet the minimum reduction for time charged.

Performing these QA/QC inspections is only going to improve the quality of my home energy audits in the long run.  Because I have always felt I lacked experience in the home weatherization industry when it comes to the final installed product.  Therefore now that I am seeing how things are installed, properly and improperly.  I will be even more specific with my notes to ensure they seal penetrations and install the insulation as I would expect them to.

So as the heat begins to rise, the pace picks up and I am sure I will hear from some hot contractors.  This time not because I am enforcing LEED requirements, but because they are defending the quality of work.  So let’s bring on the heat and new experience.

Kitchen exhaust really sucks!

Range HoodI think the title explains itself.  Commercial range hoods or downdraft exhaust are becoming popular in new homes and kitchen renovation projects.  You know they look cool or have the ability to hide in the counter top, and man can they suck.  Hold your hair piece around some of these because you could lose it.  They actually pull so much air out of the house, that they cause very harmful conditions in the home.  And I have been conducting energy audits on more and more of these homes lately and leaving with not so happy customers.

The issue that these exhaust units create is that they are pulling so much air out of the home that air has to come back into the home somehow and this is causing standard atmospheric water heaters and the less efficient furnaces that are still in operation in lots of homes to backdraft.  So anytime you turn on the exhaust, it actually pulls the combustion gases from your water heater into the home increasing ambient levels of carbon monoxide.  And this situation can occur in any old, new, large, and leaky home.

I mention not so happy customers because when I come across this condition, all incentives from the local utility to make efficiency improvements are halted until the back drafting issue is resolved because we don’t want to tighten up a home and make the conditions worst.  Although this is not really a green building issue, it is just that green builders and designers who look at how the house works as a system takes these kinds of issues into consideration.  Therefore here is a preview of a great article from GreenBuildingAdvisor.com on ways to prevent the back drafting from these high cfm rated exhaust fans that any homeowner, architect, designer & builder/remodeler should read if considering one of these units.

Makeup Air for Range Hoods

If your kitchen has a powerful exhaust fan, it may be pulling air down your chimney or water-heater flue

Most homes have several exhaust appliances. These typically include a bathroom fan (40-200 cfm), a clothes dryer (100-225 cfm), and perhaps a power-vented water heater (50 cfm), a wood stove (30-50 cfm), or a central vacuum cleaning system (100-200 cfm). But the most powerful exhaust appliance in most homes is the kitchen range-hood fan (100-1,200 cfm).

Every time an exhaust fan removes air from your house, an equal volume of air must enter. The air that enters cracks in a home’s envelope to replace air that is exhausted is called “makeup air.” Two trends affecting makeup air are causing increasing problems for homeowners: homes are getting tighter, and range-hood fans are getting more powerful.

So where does a powerful range-hood fan get its makeup air? If the house doesn’t have enough random air leaks around windows, doors, and mudsills, the makeup air is often pulled backwards through water-heater flues or down wood-burning chimneys — a phenomenon called backdrafting. Since the flue gases of some combustion appliances can include carbon monoxide, backdrafting is dangerous. In some cases, it can be life-threatening.

Challenging our priorities

As the new year begins, we all have resolutions to improve or change our lives in some way.  For the design and construction industry, I truly believe there needs to be a shift in thinking.  Energy efficiency needs to be a key player in all of our work, and I am not just talking code minimums.

As I am now performing home energy audits, I am inspecting way too many homes built before the 1960′s with small to large additions or alterations.  Yet the majority of the original structure in not touched.  This is why I am visiting these homes, they have these brand new additions and brand new high efficiency furnaces, yet they are not comfortable.  No surprise when a newly insulated addition is added to the home and the original structure stills sits uninsulated.  But what may be more disturbing is the rare addition built within the past couple of years that are extremely under-insulated at the ceiling.  And what amazes me even more is that home owners are so conditioned into thinking that they are uncomfortable because they have “bad” windows.

Basement Finishing

A recent article in my local newspaper titled “Building a better basement” explains the difference of using traditional stick framing and drywall with panel systems for basement remodeling projects.  So, naturally red flags went up for me when I saw the title.  Primarily because what we have done in the past that we thought were the right things to do, are really not and are causing lots of problems today.  Especially the four letter word “mold”.  I think back to when my father finished our home when I was younger putting up the sheet of plastic (vapor barrier) before applying the paneling to the insulated stick framing, not to mention the rotten wood I found when tearing down finished basement walls in my own home.  If you are wondering what I may be afraid of, check out a couple of studies on insulating existing basements I posted last year.  (Building Science Sunday: Basement Insulation)

I want to take a little time and explain some of these systems mentioned in the article a little further and make a couple of suggestions.  Now the good thing is that all the companies mentioned in the article all agree that the basement has to address any moisture issues if any first.  Because if you have water problems in your basement, it doesn’t matter how mold resistant a product says it is.  If the material does not get a chance to dry and is not exposed to sunlight, mold can grow on almost any surface.  So lets talk about some of these systems.
