Why Wilshire

Eco Smart Homes in Austin

To simply say that Wilshire Homes constructs energy-efficient new homes in Austin is an understatement. Wilshire Homes stands apart in the industry because of its energy efficient home plans and because it adheres to the U.S. Green Building Council’s LEED (Leadership in Energy and Environmental Design) for Homes program. This means that you are not only saving money in the long run due to reduced utility bills, but also creating a positive impact on the environment.

LEED-Certified

All of the Wilshire Homes built in Austin are LEED-certified, regardless of their size and scale. The LEED certification requires Wilshire to strictly follow mandates for indoor air quality and resource allocation to the core.

Efficiency Promise

Owners of new homes in Austin built by Wilshire Homes get a two-year limited guarantee that the cooling and heating used in the building will not exceed a capacity* as specified by the Efficiency Promise Program. Learn more at www.efficiencypromise.com.

* The energy used to heat and cool the home will not exceed the guaranteed usage listed on the front of the limited guarantee subject to the terms of the limited guarantee. The energy usage is for the heating and cooling portion only of your energy bill and is calculated on the base plan for the floor plan design built. The base plan calculation and guarantee does not include any optional rooms or other modifications listed on the builder’s option addendum, which would alter the base plan size of the home purchased whether added by the builder or purchaser. Since this is a limited guarantee of energy usage and not cost, any reference to dollar amounts is strictly an estimate and actual costs will vary with the cost of energy.

Energy Savings

Wilshire ensures that buyers are at ease, knowing that all Wilshire homes are LEED-certified. A number of building standards are utilized, including:

  • HVAC unit and duct size are designed based on both the home’s size as well as how many windows on the home
  • An air leakage assessment using a “blower door test” to reduce air leakage – air leakages contribute to up to 33% of the energy loss in your home
  • Improvements to attic ventilation by employing baffles that are above the soffit vents, which means a home that is more comfortable during the hot summer months and protected during winter against the build up of moist air
  • An energy efficient 16 SEER A/C system requires less energy, while operating more quietly
  • R-38 flat ceiling insulation, which creates a barrier between indoor and outdoor temperatures

Indoor Air Quality

Wilshire homes are constructed with air intakes that are mechanically controlled and we employ MERV air filters that allow filtration high performance 4” pleated filters.

To increase the quality of air in your Wilshire home, every one of our houses receives a thermal bypass inspection, which includes an experienced third party visually assessing the framing areas, where air barriers are frequently missed, as well as inspecting to insure optimum alignment of insulation with the air barriers. This additional step enhances the HVAC long-term endurance and saves you money.

Water Efficiency

As part of our green building program, Wilshire Homes also employ a number of water efficiency features. The most critical of these is a PEX plumbing system. The PEX plumbing system uses a manifold setup that provides hot water lines that are dedicated to every hot water fixture. Based on research by The Partnership for Advancing Technology in Housing (PATH), a manifold setup is superior to non-manifold systems that use copper by delivering hot water to the outlet twice as fast.

Resource Efficiency

At Wilshire Homes, we construct wall studs and joists for the subfloor using engineered lumber whenever feasible. Engineered lumber has several benefits, including adding value to the build due to engineered lumber being stronger. Engineered lumber also is practically free from defects and can support increased weights over a longer time. The amount of waste is also minimized by using engineered lumber, which reduces the number of trees that need to be cut down.

Moisture Management

This involves the use of a continuous draining plane to block water that can penetrate the wall cladding. In addition, air and moisture leaks are further prevented by installing adequate flashing at all windows and doors. Most importantly, we install a vapor barrier under the foundation of the home to minimize moisture intrusion.

Verification

Wilshire Homes relies on third party inspectors to verify that our homes meet all required energy efficiency and quality standards. In addition, we also have a third-party endorsement from Green Built Texas (GBT).

A Closer Look


Construction

Wilshire builds homes that are Eco Smart without downplaying the aesthetic factor and the curb appeal. Believe it when we say this: there is no feeling greater than living in a comfortable and beautiful house knowing that you are conserving the environment, getting long-term savings, and increasing the home’s resale value.

Construction/Exterior

Verified and Certified Green Home Building

The Wilshire Homes Eco Smart program warrants that our homes are certified GREEN through the Green Built Texas protocol. Green Built Texas is a recognized green building certification system, providing third-party verification that a building or community was designed and built using strategies aimed at improving performance across all the metrics that matter most: energy savings, water efficiency, CO2 emissions reduction, improved indoor environmental quality, and stewardship of resources. This makes our homes energy-efficient and environmentally responsible.

An Eco Smart home from Wilshire provides a healthier environment inside your home, is more cost efficient to operate and maintain, uses fewer natural resources and is inspected for performance by 3rd parties. What it comes down to is a CLEANER, HEALTHIER, MORE COST EFFICIENT home for you and your family.

Blower Door Test

We conduct a Blower Door Test on every home we build. This allows us to locate and correct any air leakage. Did you know that air leakage is responsible for 30-33% of a home’s heat loss? We use 3rd party providers to ensure transparency and consistency in the test.

HVAC Unit and Duct Sizing

There are several ways in which Wilshire Homes promises energy efficiencies for homes in Austin. To start off, we use a unique AC/Heating blueprint that is designed based on:

  • The number and size of windows in the house
  • Size of the home
  • Presence of other energy efficiency components

To ensure all these components work together efficiently, we accurately size the HVAC equipment using the Manual J of the Air Conditioning Contractors of America.

Water Efficiency PEX Plumbing System

What is a PEX plumbing system? It’s another way to improve resource efficiency in your new home. The PEX system uses a manifold configuration while other regular copper systems use a non-manifold setup. The manifold setup allows us to deliver hot water lines directly to bathrooms. The Partnership for Advancing Technology in Housing (PATH) conducted research that determined that the PEX manifold based system maximizes the water usage efficiency by delivering hot water twice as fast as copper systems.

ENERGY STAR® Rated Dishwasher

Energy Star rated dishwashers can save you 25% each time you use it. How? Energy Star rated dishwashers use 3 gallons of water less per load saving on water usage as well as on the cost of heating those 3 gallons of water.

Superior Insulation

Ensuring the most comfort, we build your home with optimum insulation (R-13 wall and R-38 flat ceiling). Also, to guarantee correct installation your insulation will be inspected by a professional.

16 SEER A/C System

Featuring a higher Seasonal Energy Efficiency Ratio (SEER), your Wilshire Homes A/C system uses less energy to operate making it more efficient. Additional benefits for the homeowner are improved control of the internal climate, improved energy costs and noise reduction.

Air Infiltration

To minimize air infiltration, we seal all penetrations of the floors and walls, as well as the joints between building materials.

Third Party Energy Inspections

Not only do you have our certifications and our word that we built you and energy efficient home, but an unbiased 3rd party inspector will also give you their word. Independent inspectors will direct the inspection of the home’s envelope, with the goal of insuring that each new home meets all of the quality and energy efficiency standards. Lastly, each new home receives a final inspection from an independent 3rd party to warrant that the home meets the important HERS Index.
