ENERGY EFFICIENCY

For new homes, there is no single best design or technique for achieving optimal energy efficiency. Builders now have at their disposal a vast array of materials, components, appliances and techniques. Quality work and good materials have always been hallmarks of a well-built home but an understanding of how a house operates as a system is essential in building an energy efficient home. Knowing how to properly integrate all of the building components and understanding that they all interact is necessary in order to produce a high performance home.

 

Ultra-efficient home design combines state-of-the-art, energy-efficient construction, appliances, and lighting with commercially available renewable energy systems, such as solar water heating and solar electricity. By taking advantage of local climate and site conditions, designers can incorporate passive solar heating and cooling and energy-efficient landscaping strategies. The intent is to reduce home energy use as cost-effectively as possible, and then meet the reduced requirements with on-site renewable energy systems.

This system delivers the highest standard of energy efficiency. Installation of the combines the performance benefits of the blow-in blanket system and BATT Insulation to achieve and R-21 in the wall cavity.

 

The Premium package meets all local codes and provides homeowners the most extensive insulation and air sealing program available. The Premium insulation package includes:

Wall Insulation

Install R-21 insulation cell spray foam

Attic Insulation

Install blow-in fiberglass, providing excellent coverage throughout the attic and air chutes to ensure adequate air exchange and that the insulation system works properly.

Attic Air Seal

Air sealing prevents airflow between a home and the attic. Proper air sealing helps heated and cooled air stay inside the home by closing the gaps that leak air. Air seal the top of the wall framing that is exposed to the attic (interior and exterior walls), reducing air transfer from conditioned living space to unconditioned attic space.

Basement Box Sills

Foam insulation is applied to all basement box sills. One of the thinnest areas of a home, this application both insulates and seals air leaks preventing the infiltration of exterior air and the loss of any warm air in the basement.

High Efficiency Heating/Cooling Equipment

High Efficiency Heating/Cooling Equipment

Many ENERGY STAR® qualified new homes feature a right-sized approach to high-efficiency heating and cooling equipment. By paying proper attention to air and duct sealing, insulation, and energy-efficient windows during construction, the size of an ENERGY STAR® qualified new home’s heating and cooling equipment can often be smaller than the equipment needed in a home built to the Model Energy Code. Heating or cooling a home can account for over 50% of the home’s total energy use. You can significantly lower utility bills by choosing equipment carefully.

Energy-Efficient Housewrap

Energy-Efficient Housewrap

When the air pressure outside the house is higher than the pressure inside, air wants to move to the inside. This pulls house wrap into the seams, gaps, and penetrations and inhibits the flow of air from outside to inside (infiltration). House wrap’s best use is to act as the drainage plane on a building. This control layer keeps liquid water that gets behind the cladding from wetting the building materials. It stops liquid water from going through, but it allows water vapor to pass so when the building materials do get wet, they can dry through the house wrap.

Storage (Tank) Water Heaters

Storage (Tank) Water Heaters

Water is kept hot and ready for use at all times in insulated storage tanks with capacities ranging from 20 to 80 gallons. Many fuel options are available, including electricity, natural gas, oil, and propane. One drawback of these units is the energy used to keep the water hot at all times, otherwise known as “standby losses.”

High Efficiency Water Heaters

High Efficiency Water Heater

Heating water accounts for approximately 15 percent of a home’s energy use. High efficiency gas water heaters are 96% more efficient which offers unprecedented levels of performance to meet the need using 10 to 50 percent less energy than standard models, saving homeowners money on their utility bills. Actual energy savings from high efficiency water heaters depend on family size, heater location, and the size and placement of water pipes.

When temperatures spike, drafty windows and doors can quickly turn into rising utility bills. New energy efficient windows and doors are crucial to maintaining your home’s comfort all year long, especially during the coldest and hottest months. In fact, replacing single-pane glass windows with ENERGY STAR® qualified products can save you $146 to $501 on energy costs annually.

strong>Glass Matters: At JELD-WEN, we make the right, energy efficient windows for your home. A window is more than just a pane of glass. It’s a complex unit that can be built in a number of combinations. Energy efficient windows feature an insulating glass unit of two or three panes as well as Low-E coatings, gas fill and a variety of engineering advancements that stop the transfer of heat and cold.

Calculate The Savings: Beyond the initial purchase price of a product, consider the long-term value that energy efficient products offer in terms of annual measurable savings. In addition to the savings listed above, many local utilities offer rebates for purchasing ENERGY STAR® qualified windows and doors.

Masonite Solid Core Interior Doors

Masonite Solid Core Interior Doors

Masonite has been a leader in Environmental Responsibility from the very beginning. In 1924 William H. Mason’s ground-breaking discovery–that post-industrial wood chips could be reconstituted and used to create building material–became one of the blocks on which Masonite was built.

We are committed to trying to leave the planet much as we found it. For example, no old growth timber is harvested solely for the production of Molded Panel Doors from Masonite. By-product wood chips are a vital ingredient in many of Masonite’s doors and timber that is used comes from sustainable, managed forests. In addition, our doors are made in manufacturing facilities designed to be easy on the environment.

It’s logical that the longer a door performs the less the stress on the environment. Therefore, all materials – wood, fiberglass, steel or composites – are engineered and selected for lasting durability.

LED Energy Efficient Lighting

LED Energy Efficient Lighting

LED is a highly energy efficient lighting technology, and has the potential to fundamentally change the future of lighting in the United States.  Residential LEDs — especially ENERGY STAR rated products — use at least 75% less energy, and last 25 times longer, than incandescent lighting. LED lighting is very different from other lighting sources such as incandescent bulbs and CFLs. Key differences include the following:

  • Light Source: LEDs are the size of a fleck of pepper, and a mix of red, green, and blue LEDs is typically used to make white light.

  • Direction: LEDs emit light in a specific direction, reducing the need for reflectors and diffusers that can trap light. This feature makes LEDs more efficient for many uses such as recessed downlights and task lighting. With other types of lighting, the light must be reflected to the desired direction and more than half of the light may never leave the fixture.

  • Heat: LEDs emit very little heat. In comparison, incandescent bulbs release 90% of their energy as heat and CFLs release about 80% of their energy as heat.

Geothermal Energy Efficiency

Geothermal Energy Efficiency

A geothermal system is three to four times more efficient than the most efficient ordinary system. Because geothermal systems do not burn fossil fuels to make heat, they provide three to four units of energy for every one unit used to power the system.In the winter, ClimateMaster geothermal heating and cooling systems absorb heat stored in the ground through the water that circulates in its underground loop. This heat is carried to the ground source heat pumps where it’s concentrated and then sent as warm, comfortable air throughout your home.

During the heating cycle, a WaterFurnace geothermal heat pump uses the earth loop to extract heat from the ground. As the system pulls heat from the loop it distributes it through a conventional duct system as warm air. The same heat energy can also be used for a radiant floor system or domestic hot water heating.
