Metal Roofing- Energy Efficiency

 

Reduce Energy Costs

More and more, homeowners are seeking out energy-saving building materials for their renovations and new homes, products that not only secure and improve structures but also provide long-term cost-cutting on energy bills while promoting environmental and economic sustainability in the greater community.

Cool Pigment Technology

On a building or on a home, the roof has a major impact with the absorption of heat from sunlight (Solar Radiation). The heat is either reflected into the atmosphere or absorbed through conduction into the building. Any solar radiation that is absorbed will heat the roof’s surface. The more the solar radiation is absorbed, the greater the need to find alternative means to dissipate the heat. That’s where emittance comes into play. Emissivity is measures of the roof’s ability to shed absorbed heat.

Recycling

Metal roofs typically have a minimum of 25% recycled content. This level of recycled content allows metal roofing to be routinely included on listing for “green” and recycled content products. It is also 100% recyclable when ultimately removed as part of building renovation or demolition. Other roofing materials are routinely removed and disposed of by the ton in a landfill, but metal roofing can be recycled by its entirety. Metals are exceptional building materials that can credibly claim both recycled content and recyclability by recognized definitions.

What is Solar?

Solar panels are a practical, efficient resource for near immediate production of “free” energy that reduces the dependence upon standard peak demand utilities. Unobtrusive and easily integrated into the architectural design of a building, they are available in a variety of technologies including modules of thin film, mono and multicrystalline cells, amorphous silicon, CIGS, encapsulated in plastic and glass frames, laminates, and solar concentrators. By harnessing the sun’s renewable energy they are a non-polluting energy alternative to coal and oil. Solar panels also have a proven service life in excess of 30 years, outlasting nonrenewable energy sources.

Encapsulating the attic in a home with open cell foam and removing the normal attic ventilation allows for a semi conditioned attic that replicates the temperature of the conditioned area of the home. The benefit is a more comfortable home, reduced load on the air conditioning, and energy savings.
Energy Star qualified metal roofing has reflective qualities that significantly reduce heat gain on the home resulting in lower energy bills and a more comfortable home.
We use Energy Star ceiling fans and CFL light bulbs in our fixtures and offer LED recessed can lights which significantly reduce energy demand on a home and putt off less heat than standard incandescent light bulbs.
Energy Star qualified wood or vinyl windows come standard in all of our homes. With LoE2 coating on the glass and Argon gas in between panes, these efficient units allow the home to have an abundance of natural light while maximizing comfort and performance.
Our use of high efficiency air filtration systems rated at MERV 8 or 10 capture more airborne pollutants and particles than a standard 1" filter thus significantly improving the indoor air quality of your home. These 5" think filters also need to be changes less frequently and contribute to the longevity of your HVAC system.
High Efficiency 15 Seer or better electric heat pump systems come standard in our homes and are paired with programmable thermostats. Our systems and duct work are properly sized using a Manual J calculation for each individual home. The system is then third party inspected by a duct blaster test to make sure the system is tight and has minimal leakage. The combination of these efforts will ensure a comfortable, efficient, and long lasting system for our homes.
We use open cell spray foam insulation to encapsulate all of our attics and R-19 exterior wall insulation which both exceed code requirements for insulation. These items will help ensure a comfortable and efficient home.
The use of a tank-less gas water heater or a heat pump water heater can greatly reduce the cost of heating water.
Energy Star rated appliances in our homes save an average of 30% in energy cost over standard models.
Advanced framing techniques are used to put more insulation and less wood in the exterior walls of the home while maintaining structural integrity. These techniques include California corners, 2x6 exterior walls @ 24" on center, and ladder framing of exterior T-walls.
Caulking all plates, stud-to-stud gaps, foaming around windows and exterior penetrations, and properly installing house wrap lends a tight seal to all of our homes. Our homes are third party inspected upon completion with a blower door test to check for gaps and leaks.
Basements and crawlspaces are areas of the home that must be properly insulated, dehumidified, and kept free of moisture to ensure a healthy home. We properly waterproof these areas, install footing and foundation drains, and grade around the home to ensure no water will end up in or under your home. We insulate the exterior walls of both basements and crawlspaces and then introduce an HVAC air handler or heat pump water heater inside those areas to semi- condition those spaces and keep humidity under control.
Most builders are advertising and using fiber cement siding. The problem is they are using wood for their fascia, soffit, corner boards, and other trim pieces because it saves them a few hundred dollars per home. When you go back and look at their homes 3 or 4 years later; the siding looks great but the trim boards all need to be painted again. If they are not painted they start to decay and weather very poorly. At J.W. York Homes we "full wrap" our homes in fiber cement siding and trim boards. This ensures the trim and siding on your home will stay on the same maintenance cycle and will prevent costly repairs in the future.
At J.W. York Homes we are mindful of our impact on the environment. Even though we use long lasting products, advanced framing, and proper planning to reduce the amount of job site waste; a new construction home still produces a good amount of waste. We have partnered with a local waste management and recycling company that hauls off 100% of our jobsite waste. They take the waste to a facility that sorts the waste and recycles as much of it as possible. We are currently able to recycle non pressure treated lumber, block, brick, stone, asphalt shingles, metal, cardboard, plastic, drywall, and much more. These products are then reused for such purposes as soil additives, erosion control methods, or resold to help offset the cost of recycling.
