Air sealing walls, is it the right thing to do?

Cory — Sat, 05 Feb 2011 05:21:47 +0000

It has long been known that without making your home air tight, there is no way for your insulation to perform at it true r value. For example if your walls are built with 2 X 6 studs and insulated with R-21 insulation batts, without the house being airtight, the insulation performs at a reduced R value, something around a R-17. This is caused by gaps between the studs and the insulation which allow air to leak by. The problem in the past with making a home air tight was that the process would also trap moisture in the walls, which would lead to dry rot. Back in the 80′s and early 90′s air tightness was tried by installing 6 mil. plastic on the studs and drywalling over it. With plywood or OSB on the exterior of the wall, this left no place for the water to escape. I remember walking into houses before the drywall was installed and watching the water run down the sheets of plastic. This method of air sealing was quickly dropped and no real alternative was offered. Some minor air sealing of the bottom wall plate to the floor with caulk and foaming around doors and windows is about as far as we’ve gotten with the codes.

Just this year Washington state has adopted a stricter insulation code. It is basically the old Energy Star standards. One part of the code is the requirement that all new home have a blower door test prior to final inspection. Blower door test measures the amount of air leaks a home has. New homes are required to have a blower door score of 7.5 or lower. What this means is that if the air pressure difference between the outdoors and the inside of your house is 50 pascals (50 pound per square inch) then the air in your house will completely exchange itself seven and one half times in an hour. This is still a drafty house but its a start.

By making homes airtight we obviously can cut down the cost of heating these homes. Done correctly we also can build the walls in a manor that will allow moisture to escape. This is the best way to build. In future articles I will talk more about the methods behind this type of construction

Dont miss the Tour of Homes October 2nd &3rd and Oct 9th &10th

Laupen homes LLC. is proud to showcase two homes in the OMB tour of Homes. First we will feature the Cooper home. This is the same home we had in last spring’s Green Tour. If you didn’t get a chance to see it the first time, come out this weekend and be amazed. This home was a challenge to say the least, but we persisted and the outcome is incredible. You can view photos of it on our project page and read the owners comments on our referral page.

The second home we are featuring is the Bouvier/Rogers house, also known as the hobbit house. Now we could really call it a hobbit house without a round door, so a round door it has. Handcrafted out of mahogany wood, the door has a tree carved into it. Master carpenter Mike Anderson was the inspiration behind the door. It is a must see. This home also features a “Floating Loft” over the main entrance and living room. With lots of curves and whimsical features this home is a must see.

Still being painted

But don’t let the playfulness of the home fool you. It has state of the art energy efficient systems including radiant heat and a Heat Recovery Ventilator. Six operable ski lights make for wonderful natural lighting and at the same time allow the summer heat to escape keeping the interior of the home cool without the need for air conditioning. The outstanding blower door score of 1.23, (most new homes receive a 5 or higher) made it easier to received a Built Green level 5, and Energy star certifications.

Making your home water-wise 2

Cory — Sat, 10 Apr 2010 08:43:56 +0000

How you maintain your garden is also as important as planning when it comes to conserving water. If you’re looking at limiting the amount of water you put into your garden, you will also need to limit the amount of water that flows out of your garden. You can do this is many ways:
• Pick plants, shrubs and grass that are known to develop good root systems and employ gardening techniques that improve roots. One way to do this is to mow the lawn tall, but do it frequently. The other way to do it is to pick plants that go well with your climate and soil and water them well for the first few weeks before you reduce the frequency. Keep looking out for leaves that go yellow and new shoots that look weak and pale.
• Mulching is an excellent way to ensure that your soil remain well hydrated and does not loose moisture, especially if you live in dry weather. Mulch can be conveniently prepared in your backyard using organic waste from your kitchen. A healthy dose of nitrogen fertiliser is also recommended, provided you know what you’re doing.
• Irrigation techniques are the most crucial aspect of conserving water in the backyard. In regions frequent watering is required most homeowners opt for irrigation to keep it convenient. Drip irrigation saves much more water than sprinklers which water a lot of things other than the grass. Gray water systems are another great option. Gray water is ‘wash water’ i.e. water used in the bathrooms, kitchen sinks and laundry, which is treated and then used in gardens. Gray water does not include water from toilets (which is called black water) and is perfectly safe, with few chemicals and pathogens once it’s treated and is used by a large number of families for irrigation. A gray water system is simple enough to be installed in your backyard. However, make sure you are familiar with your locality’s policies on gray water systems.

Low flow water fixtures

Cory — Wed, 31 Mar 2010 08:36:24 +0000

Installing water efficient fixtures can definitely bring in savings over the long term, for your pocket as well as the planet. Water efficient toilets save close to 4000 gallons of water per year and water efficient faucets and showerheads too, save large amounts of water as compared to conventional fixtures. However, that is not all. Most water boards and utility providers also offer you rebates on water efficient products.
The amount of rebate depends on the type of product you buy, your water board or utility provider and where you live. For instance products and accessories marked with the EPA’s Watersense label are eligible for rebate in almost all states. A list of utility specific rebates available can be found on the EPA’s Watersense website, here.
What if you’re not buying a WaterSense labelled product? There are quite a few other reputed manufacturer that offer great products and services at the residential, commercial and community level to help reduce water consumption and energy savings. For instance American Standard has been manufacturing products and services to help tackle water scarcity since the past 100 years. Their rebates page offers an exhaustive list of states where you can make savings + get your money back.
Depending on your geographic location, your county, district or state will have their local authorities and programs that work at water conservation. These partner with local water suppliers, manufacturers and state authorities to offer attractive discounts on water efficient products, systems as well as rebates. Check the websites of your local utility provider to know more about how you can save water, save energy as well as money.

Choosing a Window

Cory — Thu, 28 Jan 2010 08:04:41 +0000

With so many options, ratings and technologies out there, picking a window can be very confusing. Add to that, you will have your own criteria for look, comfort, energy savings and of course price. However, there are many resources out there that can make this quite easy for you. We’ll list them here:
• Energy efficient windows of any type are going to be more expensive than regular windows. This is something you will need to be prepared for. However, this one-time expense really pays off, and even your remodelling contractor will agree. Energy efficient windows can lead to money savings of 7-24% (acc. To the EPA) and in some climates, upto 40% annually. It is proven that in 2-3 years, energy efficient windows pay off for themselves.
• The kind of windows you will need depends largely on the climate in your region. Your climate impacts your heating and cooling requirements, your house design and your energy bills. In order that your windows provide you with an optimal solution, they need to keep comfortable as high as possible while keeping cost as low. Thankfully, you don’t have to do the math. This neat window selection tool on the efficient window collaborative website gives you how much you can save on different window types depending on where you live. Try it out here: http://www.efficientwindows.org/selection.cfm.
• As obvious, go for windows with the Energy Star rating or the NFRC (National Fenestration Rating Council) logo. Starting 2010, EPA has come up with improved energy star ratings for windows, which can get you tax credit of over $1,500. Make sure you check for a red label marked ‘Qualified until March 31, 2010’ which means the window was made according to the old rating system. The NFRC ratings will give you the values for the five criteria mentioned in our first post in this series and are also very reliable.

Windows and Natural lighting

Cory — Wed, 20 Jan 2010 08:09:34 +0000

It is very evident that the larger your window, the more natural light it will bring in. Depending on the positioning of your windows, and its visible transmittance (VT) value, your windows could provide you with enough natural light to greatly minimize if not eliminate electric lighting requirements during daytime.
VT values are generally given between 0-1. A rating of over 0.70 is the highest you can get with clear glass windows devoid of any coatings or tints. The more the number of panes, coatings and tints the lower the VT value.
A high Visible Transmittance has another advantage – it eliminates the cooling function which is usually required in a house that uses electric lighting. A high VT value is especially important when a home is built using passive house principles or design.
However, one thing to consider when it comes to VT, is that a window with a high VT value, will also admit that much more solar energy (heat) inside the room. Thus, a clear glass window with a VT of 0.8 will also have an SHGC of over 0.60 – something not at all desirable in a warm or sunny climate.
To get around this, one can use Low E coatings, which are invisible, and yet block heat gain considerably. These coatings also protect indoor furniture and upholstery from the damaging effects of UV rays. Another way is to have operable windows that you can open up to air the room out frequently. Needless to say, a good ventilation system is important when you have large windows and a sunny climate.
For windows that are low on SHGC and high on VT, look for a high Light-to-Solar gain ratio. This determines how much more light is let in without adding to the heat.

The advantages of a mini split system

Cory — Mon, 21 Dec 2009 08:00:20 +0000

1. It’s easier to install and the units are smaller than conventional duct systems. Mini splits come in different capacities depending on the area you want to use it for. However, they all require nothing more than drilling a hole a few inches in diameter through your wall. This considerably brings down you labor costs and time taken for installation.
2. It has more aesthetic appeal. The indoor fixture are usually built with very sleek design and finishing, (depending on the cost) and are come in various mounting options. For instance you will find indoor fixtures that can be installed on the ceiling, corners or walls.
3. Space friendly. The indoor and outdoor parts can have as many as 50ft between them. Thus, you could install the outer condenser somewhere inconspicuous, like the back of the house, when it won’t be an eye-sore.
4. Duct HVAC systems usually cause a certain amount of heat loss through the ducts, particularly if they haven’t been insulated well (That’s another thing – there is no insulation required with mini splits) With mini splits there’s no such issue – there’s minimal loss of heat or energy through the conduit wires.
5. The cost is comparable to a standard heat pump system. Unlike heat pumps, Mini splits only lose about 40% of their efficiency when the temp drops to zero degrees. However by over sizing the unit by 40 %,( this adds a little to the upfront cost) you will have 100% efficiency at zero degrees. Given the last cold spell we had in December, this could be money well spent.

How to build a rain water harvesting tank

Cory — Wed, 18 Nov 2009 08:00:06 +0000

We recently hired Todd and Kari Harris of The Stone People to install a rain water harvesting system at our current project “The Cooper House” The system is designed to collect approximately 1000 gallons of rain water and store it under ground. During the summer months the homeowners will be able to use this water for their lawn and plants. They also will use the water to feed the water fall which is part of our landscape. Here’s how it works.

The Cooper Water Fall

The water is first collected from the roof with normal rain gutters. From there each rain gutter down spout is connected to a series of drain pipes which carry the water to a filter. As water enters the filter, the first twenty five gallons runs right through the filter and into the ground. By allowing the first twenty five gallons go into the ground we get rid of any bad things the water my have picked up from the roof. Once that occurs, the ground around the filter is saturated and the filter begins to fill up with water. When the water reaches a certain level in the filter it begins to drain into an out feed pipe and is carried to the 1000 gallon tank.

The tank is just a hole we dug, which we then wrapped with a heavy rubber liner. Inside the liner we stacked crates similar to milk crates which provide the structure for the tank. We then wrapped the top of the crates with the liner to provide a continuous cover. Also in the tank next to the crates is a pump chamber were the pump that runs the water fall is located. There is an over flow drain on the tank to allow water to escape once the tank is full.

After the tank was complete we poured a concrete walkway right over the top of it. Since the creates are incredibly strong, you can actually drive vehicles over them if you choose. Our concrete is part of a walkway that takes you from the street to the front door of the house. We plan to install a bench at this spot in the walkway so you can sit and watch the waterfall if you choose.

The city of Olympia bases homeowner’s sewer bill on how much water they use. They get the numbers from the water meter. By using water from the roof for irrigation you not only cut down you water bill but also you sewer bill. Imagine the savings if we could use this same water for the toilets inside the house.
