The “Vita Sana”

September 20, 2016

Vita Sana”, recently presented by Marnella Homes in the Green Home Street Fair, defines the healthy indoor environment offered by this new home.  Featuring a highly efficient two stage gas furnace, electronic air filtration and HRV that combine to create indoor air quality that is seldom found in any home. Extensive air sealing and additional insulating measures help to minimize outdoor pollutants from entering the home to provide a comfortable and balanced environment.
From the foyer, the entire main floor can be viewed due to the expanse of this open concept design. From the gathering room you will appreciate the large bi-fold patio door system that opens up to a large covered patio for an indoor/outdoor experience designed for entertaining.

Past the kitchen is the iSpace, this little workspace keeps the clutter that normally finds it’s way to the kitchen counters out of view. Next the drop zone collects the day to day coats, backpacks and the like, all in one place. At the top of the stairs is the Lounging loft, perfect for video games, homework and movies. Not tucked away in a corner, but a secondary gathering space. The 9’ ceilings and oversized windows on all floors create an abundance of light and volume regardless of the seasons. With an over 7’ wide master shower, taking quick showers might be difficult. This home and community will be NGBS Emerald certified which is found in very few new homes.  With so many features included in this home for the event, it can’t be rebuilt for the current list price of $429,950.  It will be a great value for it’s future owners.  Contact Tony for a viewing @ 503-709-3900.

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.”

th

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.

The Few, The Deserving

August 16, 2011

After receiving a comment, on a post I wrote about home performance from a builder, that all new homes were ENERGY STAR certified. It occurred to me that if someone in my industry didn’t understand the facts about the ENERGY STAR new home certification then I needed to clarify this further. I agree that the energy codes for new construction have been elevated significantly in recent years. However, so have the requirements for the new homes programs of ENERGY STAR, Energy Trust of Oregon, Earth Advantage and the like.

ENERGY STAR rated homes perform to a minimum of 15% up to 30% more efficient than code built homes. These are homes that have real performance and energy efficient features and practices built in. These homes are built using higher standards for the building envelope and HVAC system. These higher standards and additional measures are verified through third party inspections utilizing duct blast and blower door testing. In addition, if the builder is serious about performance, he will have had his homes rated with one of the performance measuring systems like EPS (Energy Performance Score) or HERS (Home Energy Rating System). Here in Oregon we mostly use EPS.

The actual number of new homes certified in the United States each year is less than 20%. Here in the northwest, the 2011 year to date percentage of new homes certified in Washington State is 12.7% and in Oregon it is 14.2%.

The bottom line is, don’t be fooled by “Green” marketing and assume that a new home is certified by one of the new homes programs. Ask questions, have the builder or sales broker show you their certification. The builder might have simply installed an Energy Star rated dishwasher and recycled the cardboard from the box.

heat-recovery ventilatorDoes the quality of air in your home rank up there with the finish level of your counter tops? Maybe it should. To certify a home for even the basic level of Green or Performance building certification, a fresh air exchange is required. This is usually a fan in a utility room that is just blowing out stale air from the interior of the home and pulls in fresh air from the exterior. The downside to this is that on a 30 degree day, it is pulling in 30 degree air to your already comfortable 72 degree home. This makes your furnace work extra to heat up this cold fresh air. In addition, these fans are not balancing an equal amount of air being pulled from the home with an equal amount of air being drawn in. This can pressurize the home, potentially pulling air through unintended areas.

What you should be asking your builder for is a Heat-Recovery Ventilator or HRV. The HRV also brings in that 30 degree air, except it uses the heat in the outgoing stale air to warm up the fresh air. Depending on the model, HRVs can recover up to 85 percent of the heat in the outgoing airstream, making these ventilators a lot easier on your budget than opening a few windows.

Using a small fan, the HRV system maintains a continuous flow of filtered outdoor air in the home. To avoid pressurization the system removes an equal amount of stale, used air from the home, especially the kitchen and bathrooms where moisture and odors are heavy. These systems can change the entire air system in a home in under 3 hours.

HRVs are ideal for tight, moisture-prone homes, like here in the Northwest, because they replace the humid air with dry, fresh air. That is why an HRV is a standard feature in every Marnella Home. For the long term health of your family and home, shouldn’t you expect this of your next home?
