The Power of Infrared: In the Study of Reindeer Seeing is Believing!

December 24, 2012

Thanks to the hard work of a team of researchers in Norway (near the North Pole) and the Netherlands, Rudolph’s red nose has been explained.  The recently published, observational study: Why Rudolph’s Nose is Red, involved both human subjects as well as two reindeer. The study shed light on Reindeer’s nasal structure, and how it is ideal for sleigh pulling while flying and facing extreme temperatures.

These sure are great images!  I can’t help but think of the insight we get when looking at homes under infrared.  Missing insulation, uncontrolled air flow patterns, moisture issues, and electrical concerns are all problems identified by a skilled technician.  Maybe our advisors at GreenHomes America don’t understand the microvasculature of the nasal septal mucosa of reindeer, but they do know homes!   

May you all have a safe, warm, healthy and happy holiday.  

From each and every one of us, Merry Christmas!

Frozen Turkeys and Frozen Pipes

November 23, 2011

With Thanksgiving on the horizon and football on TV, many of us stand ready to pack it on like a linebacker for the colder months ahead, well at least in some parts of the country.  I think it’s going to be a cold one this year, I’ve witnessed doublewide squirrels around the yard big enough to take on the neighborhood cats.  By cold I’m not talking 50 degrees at night, I mean freezing, like broken pipes cold. 

Many of you across the nation know what I’m talking about, and unfortunately I’m sure many know about frozen pipes too!

Pipes freeze because we leave them exposed to the cold. Pretty simple, but why do they freeze when they run in our basement or crawlspace?  Are they really inside or outside?

The real problem is usually not the pipes, it’s often the home.  Ductwork and plumbing that runs through spaces that can freeze leads to inefficiencies, discomfort and headache.  When hot water heaters, boilers and furnaces exist in these same spaces, they work double time trying to deliver something warm to the rest of the home.  This is definitely a home performance issue.  

We could leave it to a plumber to fix it by moving the pipes, but since they were put where they are for a reason, this often won’t work.  And that heat tape you had wrapped on the pipes and forget to plug in now, is either expensive (when you turn it on), unreliable (when you forget to turn it on), or both!  The better option:  apply a little home performance and fix your home.  As with every other part of the home a trained eye will help define how to make it work best.   Insulation air sealing and you can enjoy the game instead of spending the night in the basement with a hairdryer feeling like a frozen turkey or worse with a mop after the pipes burst. 

Stay warm…and dry!

The R House: even the best intentions can use a little home performance

November 22, 2011

Our very own Maggie Mauer form the Syracuse branch of GreenHomes America was recently featured in a Syracuse article on the R House  that she now calls home.  The R-House as it is called is a result of a design competition by local non-profit and University groups.

The home was built to Passivhaus standards.  Very little heat is needed since it is so well insulated, and in Syracuse NY that is impressive.     Passivhaus is an extreme example (and typically applied to new construction) of what we do with homes everyday: excellent insulation and air-sealing, reducing the heating loads, and controlling ventilation.  

Maggie’s house was designed to include big windows which allows for the sun to heat the space quite well.  It’s called passive solar and has been worked into design for many years…and is the reason you can usually find a cat sitting in a window on a sunny day.  But in the R-House there was one oversight, those big windows help in the winter but It sure gets hot in the summer.  Unbearably hot.  

Home Performance can be needed even for high performers.  To keep it cool, we installed a ductless mini split to air condition the space in the summer time, maybe not the usual approach, but it’s an unusual home!

There were a few other design and installation details that we had to correct, including a heating system that didn’t really shut off fully, inefficient lighting, and some leaky doors that allowed the cold winter winds to whistle through.  And this is an award-winning house! 

This goes to show, the the details matter.  A lot!  And it highlights why we’re called out not just to fix 100 year old homes, but those that are only a year or two old, too.  (Maybe the should have called us in during the construction phase to help get it right the first time!)

Keep your eye on the ball…at home!

October 17, 2011

Baseball fans, great technology comes to the World Series.  In fact it’s the same technology we bring to your home.  The AP recently reported That a number of Infrared cameras will be trained on batters in the upcoming World Series games.  The cameras will be used to pick up the heat generated from friction, say when a fast ball skims off a bat or a glove.  The Fox network is trying them out this year so they won’t be used in making calls, but they could be.  Hey at least maybe we will get a glimpse of this great technology just watching the games.

At your home base, we don’t need to see the heat patterns of a knuckle ball off a bat to cry foul, but the cameras our advisors bring along in assessing your home do help you avoid the curve balls of missing insulation, moisture problems, dangerous wiring, and un-controlled airflow.  Rest assured with the right technology and skills, troubleshooting your comfort problems with GreenHomes America will help you knock it out of the park!   

Thanks,

Jason

Great Video of Home Performance in California

Here is a great video from  the California Center for Energy Sustainablity describing the Home Performance Process featuring  one of our GreenHomes America Partners: ASI Hastings.  Great work! Enjoy!

Climate Change, the Indoor Environment and Health: Pay attention, your life depends on how you treat your house.

June 14, 2011

 A recent study from the Institute of Medicine identifies how climate change affects the environment in our homes which has an impact on our nation’s health. It is Ironic that when the weather gets worse, we seek shelter indoors from extremes outside and in doing so still potentially put our health at risk. It is also reassuring that as a Home Performance contractor our work on homes is just what the “doctor ordered”. Most of the issues raised in the report are exactly the things we keep an eye out for with health and safety in mind. Every job we do starts and finishes with testing to ensure your home is a safe haven.

The report identifies 5 major issues:

Indoor Air quality: People don’t think all the cleaning chemicals under the sink amount to much but they can. We tend to leave all sorts of chemicals in our homes, leave connections to garages full of thing we shouldn’t breathe. We also have combustion appliances in our home which left un-checked can cause issues with CO. Our advisors keep an eye out for these conditions, it’s an integral part or health and safety for us.

Dampness and Moisture: Extreme weather conditions outside lead to more frequent issues in our homes as water gets in where it shouldn’t. Cooling systems can contribute to moisture issue if not handled properly and certainly basements and crawlspaces do too. There are fixes for spaces with moisture issues that we sometimes ignore until it’s too late.

Bugs and Bugs: weather and climate change can influence infectious diseases and pests and expanding the area where they flourish. A new “bug in town” will lead to new exposure for some of us and possibly an increase in pesticides previously not used before. Moisture in our home can lead to issues with mold and other pests. A home should be a healthy haven not a petri dish.

Thermal Stress: High heat especially for those not prepared or more susceptible such as the elderly, will experience thermal stress almost exclusively inside. With temperature extremes come power outages compromising our ability to run cooling systems. Treating our buildings by insulating against the heat helps buffer your home.

Building Ventilation, Weatherization and Energy use: As we experience climate change and weather extremes it gives us good reason to weatherize but it must be handled with expertise and always with a mind towards health and safety. No longer can we tighten up a home or insulate it without thinking about the whole house. GreenHomes America makes sure that every home is left a healthier home at job’s end.

“Fixing” old buildings with new methods can create new problems if not done properly.  Being a BPI accredited company   means we are committed to quality and accountability. A comprehensive Home Assessment with solutions provided to you from our team of experts will offer the safest answers to the ever changing environment inside.

When to hire a Professional

April 13, 2011

When it comes to weatherization and our search for comfort, there are lots of things homeowners can successfully accomplish on their own. Many of us have added weather-stripping or tightened up a door and these things may help, but may not make a huge impact on the comfort of the home.

 A Home Performance professional is one that focuses on improving energy efficiency as well as comfort, health and safety in a home. The reason we encourage homeowners to hire a Home Performance professional when it comes to the efficiency, health and safety of their home is simple: It’s complicated. A house is a dynamic system with many parts that interact with each other. It is not just a heating or cooling unit, not just an attic with insulation (or one that is un-insulated), a drafty room, condensation on the windows, not just a bath fan or a damp basement, but an intricate system that needs to be maintained and tuned. No one expects a furnace to work well year after year without a tune-up and in fact it’s a health and safety issue if it isn’t maintained. The same goes for the home.

Hiring a professional to assess the home can help to establish a game plan, and in Home Performance may cover the work of a number of trades such as HVAC, moisture management, ventilation, insulation and air-sealing, and that is a good thing. The value for a homeowner is that they hire someone who understands the interactions in a home, not just one part. It helps them to make an informed decision.

Hiring a number of contractors to complete a project can work too, but it certainly is harder on the homeowner, and there is also a greater risk of some details being overlooked. Either way there may be some recommended measures that the homeowner will still want to take on and that’s ok too, since now they are making an informed decision and know what they are doing is worth the effort and investment.

Speaking of investment, often when a homeowner calls a professional to fix a problem such as comfort in the home, they think of it as an expense. The work of a Home Performance Professional not only addresses comfort issues, but by increasing the efficiency of the home, the improvements often pay for themselves at the same time. The cost of hiring a professional in this instance can be a real money saver.

Insulation For Your Hot Water System

November 19, 2010

Okay, this is the last article in my insulation marathon. If you have an older hot water system and it is not already properly insulated, this adding some more insulation is of the quickest and cheapest ways to save energy.

Most water heater’s storage tanks have some insulation as a standard feature, if you want to know if yours could do with a little extra, touch it – if it is warm to the touch it could use more.

Before I go any further let me draw a distinction between electric and gas, propane, or oil-fired water heaters. Electric water heaters are reasonably easy and safe to deal with on your own, but gas and oil-fired heaters are more dangerous so we recommend that you call in a licensed contractor to insulate these heaters for you.

Let me also point out that most new water heaters have sufficient insulation, and you can void the warranty be adding additional insulation, so make sure you know what you’re dealing with before you start.

To insulate an electric water heater simply follow the instructions on the purpose-built blanket that you have purchased. If the blanket doesn’t have instructions, or the instructions are confusing, you can follow the guidelines set by the U.S. Department of Energy. Once you have your new blanket installed be sure to set the water temperature below 130 degrees F because the wiring may overheat above this temperature.

Another step you can take to save energy is to insulate your hot water pipes. Insulating piping can save energy by keeping water hot until it reaches its destination (your shower, sink, clothes or dish washer), thereby reducing the temperature you need to set your heater at by as much as 4 degrees F. You can buy purpose-built pipe sleeves for this job from your local hardware store. Make sure you match the external diameter of your pipes to the internal diameter of the pipe sleeve for a tight fit.

I think I’ve touched all bases as far as home insulation goes. As always, if you have questions give us a holler!
