Wardcraft Green Building Practices

Green building practices are important to all of us. By conserving our natural resources now, we create a future in which generations to come will still be able to enjoy the nature that the world has to offer. By improving the safety of our homes we are able to sleep better at night. Indoor air quality affects the health of the entire family, especially our children. At Wardcraft we understand these things and strive to build you the best home on the market for your family and everyone’s future.

Life safety and air quality…
Our high performance ENERGY STAR qualified homes include high efficiency sealed combustion furnaces standard so that no dangerous fumes or vapors can escape your furnace and endanger your family. To be sure, we install combination smoke AND carbon monoxide detectors standard on every Wardcraft home, to ensure you are alerted of not only a fire, but invisible carbon monoxide fumes as well, also known as the "silent killer."

Other optional air quality features such as a UV light for your HVAC system can eliminate bacterial growth in your ductwork and HEPA filters can catch microscopic particulates and prevent them from circulating in the air you breathe. An optional air exchanger or fresh air intake can also be added to bring fresh air from the outside into your home year ’round. We also offer Low-VOC paint to drastically reduce the levels of volatile organic compounds found in the paint on your walls that can be irritants to the respiratory system. We even eliminate the formaldehyde often found in fiber glass insulation.

Natural resource conservation…
Every Wardcraft home includes many natural resource conservation features standard, including engineered roof trusses, floor trusses, I-joists floors, oriented strand board panels for exterior sheathing, roof sheathing and floor decking. This reduces the pressure on old growth forests that we want to preserve for future generations.

Wardcraft also incorporates fire resistant, durable, man-made components such as fiber-cement siding reducing wood use and extending the beauty of your home for years past when other materials would have to be re-painted. Our 30 year asphalt shingles can last twice as long as standard shingles that don’t last the length of a typical mortgage. The Johns Manville fiber glass insulation is made of 25% recycled content, as well as being formaldehyde-free protecting the health of your children.

The Wardcraft systems-building method incorporates conservation efforts which drastically reduce both jobsite waste and trips to the landfill. Our systems-building practices also reduce the amount of fuel consumed while building each home by eliminating the drive-time associated with building contractors going to scattered jobsites. By bringing all the construction workers together under one roof and having several homes for them to work on in one place, we increase efficiencies and decrease drive time and fuel consumed per home.

Wardcraft offers homes with the BUILT GREEN certification in the state of Colorado, or BUILD IT GREEN in the state of California. These programs have pioneered green building practices and have set a model for the entire United States. Please visit or for more information.

Helping to Protect the Environment with Your ENERGY STAR Labeled Home
Did you know that your home can be a greater source of pollution than your car? In fact, 16% of all greenhouse gases are generated from the energy used in homes nationwide.

In 2005, Americans with the help of ENERGY STAR saved about $12 billion on their utility bills and reduced greenhouse gas emissions equivalent to those from 23 million vehicles.

Energy used in our homes often comes from the burning of fossil fuels at power plants, which contributes to a host of air pollution problems, including smog, acid rain and global warming. Simply put, the less energy we use in our homes, the less air pollution we generate.

Just one ENERGY STAR labeled home can keep 4,500 pounds of greenhouse gases out of our air each year.

By choosing an ENERGY STAR labeled home, you are joining millions of consumers who have changed to ENERGY STAR, helping our nation reduce our energy needs and building a cleaner environment for the future.

Wardcraft High Performance ENERGY STAR Modular Homes

Wardcraft's high performance modular homes are designed to meet or exceed the ENERGY STAR requirements. ENERGY STAR for homes is a US Environmental Protection Agency (EPA) program designed to raise the energy efficiency of homes built across America, by holding the builders to higher standards with third-party verified accountability. Participating in the ENERGY STAR home program will reduce your home energy consumption and utility bills.

The ENERGY STAR home program ensures homes are at least 15% more efficient than the International Energy Conservation Code (IECC) or 30% more efficient than the Model Energy Code (MEC). Our high performance homes are designed to meet that standard and depending upon your climate zone often exceed the IECC by 30%. With optional energy features your home can exceed 50% efficiency, meeting new initiatives at federal and local levels that are designed to reduce America’s dependency on fossil fuels. The ENERGY STAR program has saved billions of dollars since its inception ten years ago. In 2005, with the help of ENERGY STAR, Americans saved about $12 billion on their utility bills and reduced greenhouse gas emissions equivalent to those from 23 million vehicles.

Wardcraft high performance modular homes are designed to meet and sometimes exceed the three required aspects of the ENERGY STAR for homes program;

1) National Builder Option Package.
2) Thermal Bypass Checklist.
3) On-site verification by a local Home Energy Rater.

1) The ENERGY STAR National Builder Option Package ensures every home includes high-efficiency heating and cooling equipment, high performance duct systems, which must meet a strict level of tightness for air leakage and efficiency, Low-E windows, an ENERGY STAR qualified thermostat, water heater and a combination of lighting fixtures and appliances. The high performance duct systems makes a much more efficient system. Wardcraft Homes designs ducts entirely out of galvanized sheetmetal, including the supply AND return ducts. Most builders use vacant cavities in the wall for return air, surrounded by sheetrock and wood studs, which is extremely inefficient and loses a tremendous amount of conditioned air.

2) The ENERGY STAR Thermal Bypass Checklist is a list of required practices for reducing energy loss through a home’s building envelope. These practices eliminate air-infiltration felt as drafts, increasing energy conservation. 25% of a home’s energy bill can be lost through air leaks in the house. The Checklist requires an overall air barrier in addition to the thermal barrier (insulation). Our high performance modular homes are insulated with formaldehyde-free, blown fiber glass insulation that is hot-glued in place to eliminate any settling over the years. This insulation is designed to be blown around and behind wiring and plumbing, ensuring a tighter air seal, filling the entire wall cavity and completely eliminating any gaps, voids, or depressions typically left in batt installations.

3) The last component of the ENERGY STAR process is the Third-Party Verification performed by a local Home Energy Rater (HERS). Once the home is on the jobsite, your local Wardcraft Building Professional will complete your home to ENERGY STAR requirements and contact a local HERS rater. The HERS rater ensures that the home meets or exceeds the ENERGY STAR program’s strict requirements.

How Do Homes
Qualify for ENERGY STAR?
Homes that earn the ENERGY STAR are significantly more energy efficient than standard homes, incorporating:

Effective Insulation: Properly installed and inspected insulation in floors, walls and attics ensures even temperatures throughout the house, while using less energy. The result is lower utility costs and a quieter, more comfortable home.

High-Performance Windows: Windows with Low-E glass help to keep heat in during the winter and out during the summer. They also block damaging ultraviolet sunlight that can discolor carpets and furnishings.

Tight Construction and Tight Ducts: Advanced techniques for sealing holes and cracks in the home’s "envelope" and in heating and cooling ducts help reduce drafts, moisture, dust, pollen, pests and noise. A tightly sealed home improves indoor comfort and air quality, while lowering utility and maintenance costs.

More Efficient Heating and Cooling Equipment: Energy-efficient, properly installed heating and cooling systems use less energy, which reduces utility bills. You can expect higher quality and greater durability backed by longer warranties now available on many models.

Independent Testing: While it’s easy for builders to claim that their homes are energy-efficient, ENERGY STAR partners back that up with a third-party inspection to verify the home’s energy performance. ENERGY STAR homes also undergo an additional comprehensive inspection of insulation and air sealing details to ensure that they deliver the full comfort and energy saving that they are designed to achieve.

Wardcraft's high performance ENERGY STAR qualified modular homes are insulated to R-23 standard (most codes only require between R-13 and R-19). Wardcraft uses an innovative new product by Johns Manville called Spider Fiber in the walls. Spider Fiber is a blown fiberglass insulation, hot glued in place in our 2x6 exterior wall. This insulation system far out performs fiber glass batt insulation and other blown systems that introduce water into the building envelope. The glue used in this spray-in product introduces less than 10% moisture into the home. This approach allows a much tighter installation eliminating any gaps, voids or depressions typically left in batt installation.

Wardcraft's high performance ENERGY STAR qualified modular homes are built with R-50 standard in the attic. Most local codes only require R-30 in the attic. The R-50 we install is almost double the amount of insulation required by most codes. The system we use in the attic is similar to the Spider Fiber used in the walls, but uses fiber glass insulation that lofts in the attic space. The hot-glue is also used in the attic, with a lesser amount of glue needed due to gravity holding most of the fiber glass in place.

Using the innovative hot-glue fiber glass, with R-23 in the walls and R-50 in the attic combines to make an extremely efficient insulation package. Our outstanding insulation system exceeds the strict requirements of ENERGY STAR and the California Title 24 energy code. This ensures a quieter and more comfortable home for you and your family.

ENERGY STAR requirements include the use of high performance HVAC and duct systems which must meet strict levels of tightness for air leakage and efficiency and are designed in every high performance ENERGY STAR qualified modular home we build.

A 90% or greater high efficiency, sealed combustion furnace and a 13 SEER A/C by Payne (a Carrier company) are standard. Using the high efficiency furnace and A/C yields more energy produced per dollar you spend heating and cooling your home. Most builders use an 80% efficient furnace, which just meets code. Sealed combustion furnaces are standard so that no dangerous carbon monoxide can escape your furnace and endanger your family. An optional heat recovery ventilator (HRV) brings in fresh air from the outside, preheats the incoming air during the winter and precools the incoming air during the summer. It can provide clean fresh air every day while helping to keep energy costs low.

We design your duct system with specialty software, ensuring proper sizing to maximize efficiency. We maximize air flow by using all sheetmetal duct supply and returns and by locating the furnace within the central 1/3rd of the home, which minimizes long duct runs that are less efficient. We minimize duct air leakage by sealing all connections with duct mastic that seals much better and lasts much longer then traditional duct tape (which typically only lasts 10 years before losing adhesion) used by most builders. The value to you will be reduced energy costs for your family month to month as long as you live in your home. As energy prices rise dramatically over the next decade you can rest assured that you made one of the best investments in your life with a Wardcraft high performance ENERGY STAR modular home.
