Why Marnella Homes?

August 8, 2016

When looking through the many listings for different builders and their homes, what makes their homes different from one another?  It is far more than just the architectural style and price range.  As I often say, “what is behind the sheetrock is as important, if not more so, than what is in front of it.” I encourage anyone looking at a new home to walk the builder’s homes prior to the installation of sheetrock to see how they are assembled. You will see a lot of surprising things, not all good.  A few things that are in built into every Marnella Home are; Advanced framing, extensive air sealing, blown-in insulation and HVAC systems that are in the conditioned space.  These are just some of the features that, with all we know about building science today, it still surprises me that more builders refuse to build with these systems.

More wood is not better.  However, that is the theme amongst most builders because it is how they were taught.  They are just following the lessons of their Grandfather, Dad or the mentor that got them started.  In the new way of building, less wood is better.  The Advanced Framing technique, utilizes less wood which means room for more insulation, which means a more comfortable and efficient home.  This style of framing really stands out from conventional framing.

Extensive air sealing isn’t just filling over-cut openings in the exterior shell of a home.  It is the air sealing of every seam and joint in the exterior shell of a home.  The benefit of this is not simply to improve efficiency and energy loss, though important, it is also to improve the health of the indoor environment by sealing out pollutants that can be drawn into the home.

Blown-in insulation is so important to effectively insulate a home.  Installing Batt styled insulation is such an inferior way of insulating, yet still most common.  The insulating performance of insulation is its thickness.  So, why does anyone expect that a compressed batt, forced over plumbing or wiring in a wall, is going to perform to it’s intended performance?  I know, right?  It can’t.  That is why blown-in insulation that completely fills a wall cavity, regardless of what is in its path, will perform to it’s intended performance.

HVAC systems in the conditioned space is one of the smartest moves that we have made in our homes…ever.  Not only are these systems exponentially more efficient than a standard forced air system, but they create a more comfortable home.  In 2007 we moved our HVAC systems inside the home, our service calls for uneven heating/cooling  and requests to have the systems balanced, stopped completely.

So, as you are looking around at new homes, remember to look at the homes in their pre-sheetrock stage.  Food for thought, a home built to the building code minimum, is really a home that is barely legal.  Anything less, and the building inspector would not approve it for occupancy.  On average, a Marnella Home is built to 35% over the code minimum.  The benefits to our homeowners include, lower maintenance, lower heating & cooling costs, greater comfort and lasting value.

Healthy Homes

May 14, 2016

Marissa Harshman, a writer for the Columbian, published a great story this week about the health, or lack there of, in homes.  Most of the marketing of Green building promotes energy savings and sustainable products.  However, one of the greater benefits of these building systems is the improved health of the indoor environments and it gets the least promotion.  In my opinion, it should be the top benefit followed by durable sustainable products, reduced maintenance, energy costs and consumption.

Marissa writes, “A person’s health can be affected by numerous things — diet, physical activity, family history, lifestyle choices. But one factor people don’t often consider is their home.”

Green homes, use low voc (volatile organic compounds) paints and caulks to prevent harmful off gassing that traditional paints and caulks emit.  People often say they like the “new” smell of a home or car.  However, they are really enjoying the smell of harmful gases that are being released into the air.

Every Marnella Home has an indoor environment built to EPA’s indoor airPlus compliance because we agree with the importance of maintaining a healthy home.

“Some of the most common causes of sick homes in the Northwest are ventilation systems not working properly, water entering wall cavities and causing mold growth, and unsealed spaces allowing air from crawl spaces to enter the home.”

Our vented rain screen siding system helps prevent moisture from entering in through walls and is installed on every home we build.

All of our HVAC systems are installed within the conditioned space (inside the home and not in the garage, attic or crawlspace) to provide superior performance and efficiency.

Green homes also have very low air leakage which minimizes outdoor contaminates from making their way into the home and incorporate mechanical fresh air exchange equipment which continually exchange stale indoor air with fresh outside air.

I encourage you to read Marissa’s story and consider the benefits of Green and performance homes when looking to buy or build.  Remember, what is behind the sheetrock is just as important, if not more so, than what is in front of it.
