Balanced Ventilation in a Timber Frame Home

 

For nearly 20 years, Goshen has encouraged clients to incorporate a balanced ventilation system into their heating and cooling units. Whether an energy recovery ventilator or a heat recovery ventilator, depending on the climate where you build, the balanced ventilation system is an important part of your H VAC system.

A balanced ventilation system replaces the exhaust/supply system by supplying  fresh air to bedrooms and living rooms, the most lived in areas, and exhausts air from rooms with more moisture and pollutants (kitchen, bathrooms, laundry rooms). The balanced ventilation system is important to a healthy house.  

We’ve often suggested that balanced ventilation systems will be required by code and from what we are seeing, this will happen sooner rather than later. Homes are tighter and stale air is a health hazard.  It’s time for these systems to be more widely utilized.

There are basic balanced ventilation systems and more specialized energy recovery ventilators and heat recovery ventilators. You should work with your local heating and cooling contractor to determine the best unit for your climate and your home.

And, wherever and whatever you build, as always, we encourage you to Build Boldly.

Timber Frames – A Responsible Choice

The three R’s in the decades old sustainable living code – Reduce, Reuse, Recycle – can easily be extended to include another “R” or even two.  Making “responsible” choices is yet another step in the right direction.  Decisions we make daily impact much more than our daily walk.  Small decisions have long term benefits.  Decisions we make on a larger scale can bring both short term and long term benefits.

When we make responsible choices as we build, we protect the environment.  Timber frames (designed to fit the land and to be energy efficient, built with sustainable materials) make building responsibly much simpler than most building methods.

Reconsider is the 4th “R” .   This article  explains that wooden structures become storehouses of carbon.  The facts are there, it’s just up to us to make wise choices.

So whether the 3 R’s expand to include “Responsible” and “Reconsider” is up to you as you plan your new home.  A timber frame home will help you to move in the right direction and will serve you well.

 

 

 

Five Steps in Choosing a Timber Frame Company

As you begin the design/build process, you’ll talk to one or more timber frame companies about building your timber frame home.  How those conversations go will often determine which company you work with as you move forward.   If you..or they…aren’t asking the right questions, you could miss an opportunity to work with a great company or you might end up with a company that might not work well with you.

1)  Educate yourself.  Your initial meetings will go much further if you’ve spent some time on the Internet educating yourself about the timber frame building process, styles of timber frames, and the difference between timber frames, log homes, and conventionally framed homes.  This will help you to better understand their answers in the “timber frame” context.

2)  Narrow down the companies you want to consider to two or three.   You might send off an exploratory email or make a call to a few more to help you narrow down your choices.  There are great timber frame companies all across the country.  Each one has their own “package” and business model.  The differences may be subtle or blatant, but if you look at too many, you’ll only be confused, not better served.

3)  Don’t be intimidated or insulted if they ask about your budget somewhere in the early conversations.  They aren’t doing you a favor by making you think you can build more home than you can afford.  Be frank and be willing to listen to them when they tell you that you can build within your budget, but you’ll need to make some tough decisions if you are trying to build more home than the budget will sustain.   However, if their focus seems to be on your budget and time frame and not on you and your project, you might want to think twice.

4)  Build with someone you would like if you met them outside of the timber frame context.  Designing and building a home can be stressful.  If you are working with someone that you can communicate with on a very personal level, then you are ahead of the game.

5)  Make sure that they have a system in place to share plans and work in progress with you and your builder.  Whether it is by emailing PDF files to you as updates are made or having web meetings or phone calls, determine what works for you and go with a company that is can keep things moving forward easily.

All of that said, just move forward confidently and when you build…build boldly…Bonnie Pickartz

Timber Frames, Heavy Timber, and Post and Beam Construction

You’ll often hear the term “heavy timber” and “post and beam” when timber frames are discussed.  The terms have come to be used interchangeably, but there are also differences.

Heavy timber can be used to indicate large lumber which is usually expressed in actual sizes (an 8 x 8 timber is really 8 X 8 ) instead of nominal sizes where a 2 X 4 is usually 1 1/2 X 3 1/2.    Timber frames are always built with heavy timber.

Post and beam can indicate heavy timbers attached to one another with metal plates, bolts, joinery, or a combination.  While the term is often used to mean “timber frame”, it doesn’t have to be traditional timber framing.

A 12″ X 22″ X26′ timber ridge beam, shown below, definitely qualifies as heavy timber as it becomes an integral part of a timber frame home.

Green Building Notes – The Materials in Your Timber Frame Home

Choosing the materials you will use in building and finishing your timber frame home will be a critical next step. Using high quality, environmentally responsible materials is key to building a green home.  Sustainability, energy efficiency, and the impact of the products you use on the health of the homes occupants are the key elements in building your new home.

High performance products that are produced by companies committed to the environment have been and continue to be developed.  Building with regional materials is a responsible way to build with lower embodied energy.  Products that have increased durability and reduced maintenance will continue to pay off long term. Energy efficiency is important in all decisions from appliances to windows.  Be sure to use Energy Star rated components whenever possible.

As a client of Goshen Timber Frames, you will choose to build a home that is either a timber framed home wrapped in R-24 wall and R-40 polyurethane structural insulated panels, a hybrid home consisting of some timber framed areas and other areas built with the same structural insulated panels with timber roof support, or a panelized home built with structural insulated panels with timber roof support. Any of these options have given you a head start on building your home in a green, responsible fashion.

Explore the options for finishing your new home carefully.  Take your time in making these decisions.   Even when you are looking for a cost effective option, you will have many choices.

*  Durability is key to the materials and products you use.  Durable products are less likely to end up in the landfill in a few years.  The manufacturing process is very energy intensive.  The more durable, longer lasting a product is and the less maintenance it requires, the more energy it saves.

*  Gather samples so you can compare the color and quality of your choices.

* While it is comforting to buy from companies with a responsible track record and with names that we’ve heard for years, don’t rule out a newer company who is offering a product that is comparable and is getting good reviews.

*  Buying a product that is available regionally can help keep your project timeline on target.  Waiting for a special order product that has to be shipped from another country or region can cause delays.  Transportation is costly and polluting.  Locally or regionally produced materials save money and are more environmentally responsible.

*  Keep in mind the long term maintenance and longevity of the products you choose.  No matter how much you like a product, research how much time and money will be required to keep it looking good.  Will the product need to be replaced in a few years?  Will the maintenance be a drain on time and resources.

*  Recycled and salvaged building materials can add charm to your home and reduce landfill use.  Sacrificing energy and water efficiency by reusing windows and plumbing fixtures isn’t a good idea, but interior doors, moldings, cabinets, hardware, and lumber are all good choices.

*  High efficiency heating and cooling equipment, properly sized for your home and insulation values, save money and produce less pollution.  Mechanical ventilation is necessary in today’s tight homes.  Energy or heat recovery ventilators will ensure healthy indoor air.

*  Water efficient plumbing fixtures (water conserving showerheads, toilets, and faucets) save water and reduce the demand on septic systems and sewage systems.  Reducing water usage saves on the water system and reduces energy costs to heat the water.

*  Listen carefully to your own voice as you make decisions.  The input of the professionals is critical, but you and your family will live in your home.  Accept their suggestions and advice, but use only what works for you and your family.

The above items are the big picture.   The harder decisions will be smaller, more detailed, but every bit as critical to building a sustainable, energy efficient home.  Your home as a whole is the end result of many, many smaller pieces.   We will start defining energy efficient and sustainable building products early in the design/build process and will be available to help you evaluate your choices.

Building a sustainable, energy efficient timber frame home doesn’t have to be difficult and isn’t rocket science.  Just spend the time and energy necessary to make good choices and you’ll end up with a home built for generations.

And when you build…don’t forget to build boldly.

Two Goshen Timber Frames Going Up This Week

Team Goshen has been busy. This week two new homes will sport Goshen frames! With interest rates down and interest in beautiful, energy efficient, sustainable homes up, Goshen is busy.

Howard and Cindy worked with Goshen to design and build their new home in the far western mountains of North Carolina. A great home!  And Goshen partnered with architect Philip Buchanan to design and build JohnGoshen Timber Frame Home and Barbara’s new timber frame near Asheville.  A great contemporary home with beautiful lines.

Timber Frames with SIPS and Energy Efficiency

The very first step in building a sustainable, energy efficient home is to make sure that you have a well insulated shell.  Timber frames and hybrid timber frame homes when enclosed with structural insulated panels are a great beginning.

R-values don’t tell the whole story.  If a wall has a high R-value and isn’t sealed properly, the efficiency is lost.  With most insulated panels thermal breaks are minimized and there should be no leakage.  Windows aren’t as efficient as walls, but proper sealing will minimize the loss of hot and cold air seasonally.

As you plan your new timber frame,  look at the different enclosure options.  At Goshen we enclose all of our homes (and build the hybrid portion of our hybrid timber frames) with polyurethane core structural insulated panels.  They go up quickly, wrapping the home in an energy efficient shell, and offer maximum R-values per inch of thickness.

With an R-40 roof and R-24 walls, we are seeing minimal cooling and heating bills in all of our homes.  Our personal energy bill for the month of July is posted on our Building A Timber Frame Blog .  We didn’t take extraordinary steps to minimize the utility bill,  kept the house at a comfortable temperature, and have been pleased with what we’ve had to spend to heat and cool.

For a look at a hybrid timber frame home raised and enclosed in insulated panels, check out this video by Rick and Debbie in Dahlonega, Georgia. They will soon be moving into

their new home and expect excellent performance from their panels (and exceptional beauty from their timber frame home). I’m sure they won’t be disappointed on either account.

So, do your research and build an energy efficient home and enjoy the benefits for many, many years.

Green Building Notes – Your Timber Frame Journey Begins

One of the first things you should do as you begin your design/build process is make a decision as to whether you will build a “green certified” home. If you decide to do this later in the process, you may have to take steps backwards and redo some things in the construction process. Certification is widely believed to add value, so if you are going to sell the home, this may be a wise option. It also requires oversight and a decision about the class of certification you wish to achieve. As the trend to build homes to meet higher green standards moves forward, certification may or may not have a large impact on the economic value of the home. What will continue to be important is the quality of the home and the measures taken to ensure that the home is built to the highest standards.

We’ve included a checklist of issues that should be addressed in the green design/build process whether you choose to have your home certified or not. Also included is a comparison of the two most common green building standards. Both LEED and NAHB Green Building certifications require builders who are registered within the programs. You must determine which, if either, certification you are seeking early in your design/build process. They both offer extensive documentation. Nationwide there are local and regional certifications that offer similar certifications. They also provide documentation and lists of inspectors who can help you meet their requirements.

Our goal is to provide a list of best practices for building your new Goshen home that are important whether or not you decide to build a green certified home. The Goshen Timber Frames Guidelines are meant to provide a direction and to help you as you wade through the seemingly overwhelming “green building” books, articles, and websites. These guidelines are not meant to meet requirements for any certification program. They will help you to build a green home.

Once you have selected the items on which you will focus and include in your building process, documentation is important. Copies of invoices and inspections, photos, drawings, and any notes you make should be logged faithfully. Start a notebook and be diligent in your documentation.

The location of your new home will be the first step in building your green home. The value of your green home begins with the land on which it sits. Careful site evaluation early in the project will guide your design process in the right direction.

* Will you be building in a rural or an urban area?
* Will your site require extensive site development?
* Will your site allow for your home to be situated for active or passive solar energy or for daylighting?
* Will local or subdivision building requirements allow you to build a home in the size/style you wish?
* Are there important natural features that need to be preserved.

Site the home to minimize the impact on the land. By keeping roads and utility access short you less your impact on the land and save money. Try your best to utilize previously used or degraded areas for the building, parking, and roads.

More local building departments are requiring onsite water management. Working to make sure that stormwater is managed, preventing runoff that will carry topsoil away and will pollute streams, and using a resevoir system to capture rainwater to use for irrigation are all ways to be a responsible landholder.

Protect trees during construction. Fence the trees at the drip line to avoid construction traffic and debris.

Landscaping will play an important part in the energy efficiency of your new home. Trees to protect the home from the glaring sun will significantly reduce cooling costs.

Green Building Notes – Your Timber Frame Journey

Green Building, in it’s new and sometimes abused persona, is not really a new concept.  It has always been important to use resources wisely, to build with the materials at hand, and to conserve energy.  New technology has helped us to achieve some of these goals, but if we look back, we see that many before us have built green, without all the hype.  Adobe homes protected Native Americans in the Southwest from sweltering heat, wattle and daub homes used materials at hand to build shelters, skyscrapers built in the late 1800’s made use of urban space.  So while architects, designers, and builders today would like to take credit for this movement, they are truly just making the public more aware of the importance of building green.

The goal of Goshen’s Green Building Notes is to inform and educate.  Choices are many and often confusing.  Whether you choose to build a home that is certified by one of the many certification programs, (LEED, NAHB, many local and regional options), or to build a home using best practices without certification, is a very personal and budgetary decision.

Goshen Timber Frames has designed and built green homes for many years.  We’ve helped our clients design and build homes that fit their lifestyle and budgets while not encouraging them to overbuild.  Our material and energy efficient homes sit quietly nationwide, enjoyed by families of all ages and economies.   

Your site will be all important as you move forward with your project.  Whether you own your land or you are just beginning the search for a site for your new home, you need to consider how the land lays, how your home will be sited, and the impact of building on the site.  If you are building in the mountains, The Mountain Home Guide is a good place to start.  This guide was created with much input and thought by professionals in North Carolina.  

If you are looking at land, consider how you will live in your new home.  Are you a “house mouse” or a “field mouse”?  Will you spend much time outdoors or do you prefer to spend your time inside?  This will impact everything from how your home is sited to how it is designed.  Don’t hurry this process.  Changes after the fact are time consuming and expensive.  

The smallest footprint will have the smallest impact.  This is critical to your new home and should be taken very seriously.  But, just as you shouldn’t build too much home for your lifestyle, don’t underbuild either.  Your home won’t serve you well if you have to add on to live comfortably.  There is a perfect fit for everyone.  

Designing your home to work for you and to fit on the land will take time and energy.  You will need to walk the land, visit with local builders who are familar with not only building, but with the regional landscape, have a local excavator out and discuss the impact of building on the site and how the landcape will change in order to accomodate your new home.  If you are building for a view, take a ladder to the site, climb up and look around.  This will likely be your first floor view.  If the site is challenging, consider renting a lull or bucket to get an even higher view.   Take your time.  If you have the luxury of visiting the site during all four seasons, you are far ahead of the game.

Building green encompasses every aspect of designing and building your home.  As you move forward, you will have to make many choices.  We’ve listed some of these choices and offered some suggestions.  There are hundreds, maybe thousands, of books and other resources available on green building.  It is a touch phrase and has become a hot topic.  In our next few posts, Goshen we will to offer some of the simplest decisions you can make that offer the largest impact.

Green Tax Credits for Your Timber Frame Project

Credits are available for a number of energy efficient projects in your timber frame home.  Whether you are planning a new home or considering upgrades to make your home even more energy efficient, there are federal and state tax credits available.

Some credits expire in 2010 and others will be available for several years, so you can plan your projects accordingly. State credits vary greatly and some incentives are made available by counties. Energy providers offer incentives for energy efficient homes. A timber frame home, enclosed in energy efficient insulated panels, is a great start, but making wise choices for everything from plumbing to heating and cooling can help you to recoup some of the money you spend to save money.

The Database of State Incentives for Renewables and Efficiency (http://dsireusa.org/) offers a look at what is available in each state, including amounts and dates.  The Energy Star website provides guidelines for federal tax credits.

While most contractors are well versed in these incentives, homeowners should do their own research and work with their contractor to ensure maximum benefits from the programs.   In North Carolina, a homeowner can receive up to 65% in combined federal and state tax credits for a geothermal system.

As you plan your timber frame, consider how you can take advantage of the credits, rebates, and incentives available. You are planning for long term efficiency and recouping costs quickly, so plan wisely.
