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.

If not, it should. There are two typical siding installation processes here in the Northwest, Rainscreen and “vented” rainscreen. Rainscreen is a siding installation process which allows the water that can get behind the siding, to drain out, with the help of a “drain wrap” house wrap, at the bottom near the foundation. Which is an improvement to old methods because it isn’t a question of whether water will get behind your siding, it ‘s what is it going to do when it gets there. However, vented rainscreen is a system that allows the siding to breath by installing the siding material on top of furring strips of apx. 3/8” – 1/2” in thickness and providing venting gaps at the bottom course and at the eave.

wood-with-labels_lgThe reality is wall systems used to breath. A lot. Older homes were not built tight so air flowed in and out which allowed them to breath. However, when your entire home breathes on it’s own, your home will be drafty and you have no control over your energy usage and indoor comfort. So, as the homes have become tighter, we have had to find ways to mitigate the tightness with the good ventilation that has an effective purpose. At Marnella Homes, every home we build has a vented rainscreen siding system. We feel this is a superior system to the drain wrap method, due to the fact that it does not rely on gravity and tiny water channels to get the moisture to eventually drain out (you hope). It allows air to circulate behind the siding to more quickly dry out any moisture that finds it way back.

It is my belief that as the siding manufactures press for this method of installation, it will be seen as the minimum standard for siding installation in the years to come. It is already a requirement on most commercial applications.

Another benefit besides the drying of moisture is that siding will retain paint and sealant longer due to the siding material being allowed to stay dry. If the siding material is continually wet it will become more difficult to adhere too. So, an added benefit to this system is reduced maintenance.rainscreen

So, if your builder isn’t installing siding this way, ask him why.   The reason is usually because they don’t believe in it or think it is too expensive. Do your research and you will see that having to tear off siding to repair rot is much more expensive than installing the correct way the first time.

The english translation is “Solar” however, to us it means clean affordable energy.  It also could mean, “what do I do with the extra money in my pocket each month?”  It could actually be quite confusing for your family. If your combined monthly gas and power bills are only about $40, what would you do with the extra money each month?  Would you take your family out to dinner, treat yourself to a massage, put the money into savings or pay down your mortgage?  That’s the dilemma that the homeowners of our Solare Collection at Meriwether in Oregon City have.

This collection was designed from the ground up to be highly efficient, luxurious, healthy and comfortable.  This integrated performance provides low energy cost and low maintenance living.  All which result in a lower cost of ownership than any other comparably sized home.  New or used.  Over the last 30 years, PGE has increased their power rates on an average of 6% a year.  With the solar program we have through SolarCity, our homeowners have control over their power costs for the next 20 years.

Stop by Meriwether and experience the difference of a Marnella Home.  You will not only see and feel the difference, but you will realize the difference year after year of comfort and energy savings that our homes deliver.  In addition, why the program lasts, our homeowners will receive a $6,000 tax credit from the State of Oregon for the Solar in this collection.

The Few, The Deserving

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?

If your home has a furnace installed in the garage, it most likely is. At one of our Construction 101 classes at Volare our Town Home community in Happy Valley, this came up. We have been installing our entire HVAC systems inside the conditioned space of our homes (meaning the interior living area of the home). We realized the obvious benefits of: improved performance by reducing the length of duct work for the air to travel, by not installing ducting in the attic or crawlspace spaces as they are much hotter or colder than the air we are providing to the rooms that need it. Another benefit is, if the duct system leaks air it is only leaking into your home not the outdoors. However, it never occurred to us the air quality benefit of a furnace in the home versus the garage.

The furnace unit that is installed inside the conditioned space is a “Sealed unit” this means that the cabinet of the furnace is entirely sealed up. Unlike, most furnace units that are installed in a garage. Most people can recall being near a furnace in a garage when it started up and seeing the flame burning through the venting of the front of the furnace cabinet. What probably didn’t come to mind was that when the fan motor started up it was pulling air from within the garage. This could be including the exhaust from the car, gas fumes from the gas can, bag of yard fertilizer, etc. Anything off gassing in your garage could have its fumes spread throughout your home.

The great benefit of a Marnella Homes system being entirely with the home is that it is only pulling fresh air from the exterior of the home with the assistance of the HRV (Heat Recovery Ventilator). The HRV periodically exchanges stale interior air with fresh outside air. This provides interior air quality that is superior to any traditionally installed HVAC system. This should be especially important to anyone with children that have asthma or any other respiratory health issues.

So, should you be stuck with a traditionally installed system in your home, consider this when you are letting your car warm up in the morning and you might want to find a better place to store the gas can, fertilizer bag or anything that you smell when in the garage. However, if you are looking at buying a new home, you owe it to you and your family’s health to consider how your next HVAC system is installed.

Performance rating for new homes is equivalent to the Miles Per Gallon (MPG) rating for a car. Whether you chose your next car specifically because of it’s MPG rating or not, in most cases it at least makes up some part of the decision making process. Especially, if you were buying a car last summer. The building industry believes that energy efficiency, utility costs and environmental impact are factors to consider when buying or building a home. They can affect the real and perceived value of a home. The Energy Performance Score (EPS), developed by Energy Trust of Oregon, provides a clear and quantitative way to compare a home’s energy use and costs. The lower the score, the more efficient the home is and the lower your estimated utility costs.

A home energy rating involves an analysis of a home’s construction plans and onsite inspections. Based on the home’s plans, the Home Energy Rater uses an energy efficiency software package to perform an energy analysis of the home’s design. Upon completion of the plan review, the rater will work with the builder to identify the energy efficiency improvements needed to ensure the house will meet ENERGY STAR performance guidelines. A home’s EPS is based on many factors such as the home’s size, level of insulation, air leakage, heating and cooling systems, major appliances, lighting and water heating. The rater then conducts onsite inspections, typically including a blower door test (to test the leakiness of the house) and a duct test (to test the leakiness of the ducts). Results of these tests, along with inputs derived from the plan review, are used to generate the EPS for the home.

Marnella Homes, as an Energy Star and Earth Advantage Certified Master Builder, is using this rating system. Our homes have an EPS as low as 42 up to 52 which rates our homes as some of the most efficient new homes built in Oregon (as Compared to an average home score in Oregon of 81). Our homes have an estimated average monthly energy savings of $40 – $50. Our home owners realize that choosing an energy-efficient home not only benefits the environment, but can also help you save money.

We see this as a “separating the wheat from the chaff” on the over used “Energy Star Certified” claim that too many builders use. We see many builders that state that they are building homes to Energy Star Certification. A consumer doesn’t know whether they build 100% of their homes to this certification or 10%? Do they just meet the bare minimums to achieve the certification or are they truly committed to Green Performance building and exceed the minimum. As I have stated in an earlier post, whether a builder is doing just the minimum or much more, their homes usually have quality controls that are inherent to building to any level this certification. Which makes a “Certified” home in most cases still a better value than any “Uncertified” home. However, this rating system will clear away this confusion. The score will tell a consumer, if educated on what it means, all they need to know.

So, whether a low EPS score is the deciding factor in the purchase of your next home or just “a” factor, it will be made available to you by participating home builders. Our industry hopes that this rating system will be easy to understand and will be adopted by consumers much the same way as the MPG rating is in the auto industry. As this becomes more main stream it will become one more tool that consumers can use to make informed decisions on their home purchases.

No it isn’t what my sons do and giggle or what happened in that embarrassing situation in the elevator.  Offgassing or outgassing is what we tend to call the “New Home Smell” or “New Car Smell”.  We think we want it, but do we?  This smell is actually gases emitting from the materials in our new homes and cars. Like, carpet, vinyl, paint, etc. and even furniture. 

The Energy Star New Homes program requires that builders within their program build at a minimum of 15% above the code requirements.  However, Marnella Homes is building to 30 – 35% above code requirements with 100% of the homes we build.  Improved indoor air quality is one of the criteria that we must address. This begins by using materials that have low volatile organic compound (VOC) content.  VOCs include a variety of chemicals, some of which may have short and long-term adverse health effects.

To meet the requirements of the New Home program’s indoor air quality criteria, we use Green Sealed Certified carpet and low VOC content paint and caulking.  Since these products contain much less VOC they don’t emit as much VOC as similar uncertified products.  This is amazingly noticeable when walking into a home built with standard products without the indoor air quality consciousness compared to a home that is built to the Energy Star indoor air quality standards.

Whether you already have health concerns that require this attention to indoor air quality or not, you owe it to you and your family’s health to educate yourself on the importance of it. So, when looking for a new home, look for the Energy Star label.  Ask questions and investigate what, if any, indoor air quality features the builder is offering.  These features will not only benefit you as an occupant of your new home, but will provide lasting value to you when you resell in the future.
