Why Coventry

Eco Smart Homes in San Antonio

The construction of energy efficient new homes in San Antonio is only the first step for Coventry Homes. Our building program is taken to the next level by meeting the strict mandates set by the Environments for Living (EFL) Program.

This means that when you buy a new home from Coventry Homes, not only do you benefit from the highest levels of energy efficiency, but at the same time, you also leave a smaller impact on the environment.

Energy Savings

Each Coventry home is Environments for Living (EFL) certified. EFL is an initiative that goes beyond the guarantees provided by the well-known ENERGY STAR® program. On an average, homes built by Coventry are over 50% more efficient as compared to homes build earlier than 2000, and 15% more efficient than homes built according to the standards set by the ENERGY STAR program. Following are the energy-saving building standards employed by Coventry Homes:

  • The attic is kept well-ventilated using rafter vents and baffles. This keeps your home comfortable during summers and guards it against the building up of heated air during the winters.
  • Custom HVAC unit and duct sizing that is based on the number of windows, and size of your home.
  • R-38 ceiling insulation builds a barrier between indoor and outdoor air temperatures, which therefore provides you with great energy savings in your home.
  • A programmable humidistat or thermostat to counter rising humidity levels.
  • A 16 SEER A/C system, which is quieter as well as energy efficient, as it requires less amount of energy to function.

Indoor Air Quality

Homes built by Coventry are equipped with mechanically controlled air intakes and 4-inch pleated MERV air filters, ensuring optimal air quality and easy breathing! To ensure air quality is not compromised, Coventry performs a thermal bypass inspection on each home that it builds. This also includes a third-party analysis of the areas where air barriers are frequently missed, as well as an insulation inspection to make sure they are properly aligned with the air barriers.

By doing so, it is made sure that the thermal barriers and air barriers are functioning continuous and complete. This, therefore, decreases the amount of air infiltration, increases the durability of your HVAC system, and saves you money.

Water Efficiency

Coventry Homes improves water efficiencies in your home by making use of numerous smart features, with the PEX plumbing system being the most notable. It has a configuration manifold, which provides hot water lines to every outlet. A study states, this allows the water to reach the fixtures twice as fast as non-manifold systems.

Resource Efficiency

Coventry Homes also makes use of engineered lumber during the construction process, whenever it is applicable. Since this engineered product is virtually defect free, unbelievably strong, and not to mention has the capability to withstand huge loads over long time spans. This move in turn adds value to the construction.

This also keeps waste at a minimal, as only a few trees need to be cut to produce engineered lumber. Moreover, to minimize the impact on the environment even further, by-products such as unusable pieces of wood or small chips can also be used in engineered wood products.

Moisture Management

Proper moisture management goes a long way in protecting the health of your family and increasing the durability of your home! That is why Coventry Homes uses a drainage plan to prevent water from penetrating the wall cladding. All the doors and windows are installed with proper flashing to protect your home against moisture and air leaks.


Coventry Homes are RESNET and EPA certified. Not only this, Coventry also actively participates in the Quality Assurance Program by RESENT, which certifies new homes in San Antonio through the inspection of third party professionals. Moreover, Coventry also follows the standards of the Environment for Living Program, and Department of Energy Builder’s Challenge, so you can rest assured that when you buy from Coventry, you would get a home that will last you for generations!

A Closer Look

Our homes are built to EcoSmart standards and fit a broad spectrum of aesthetic tastes and retain their curb appeal while being more energy efficient, healthier and environmentally responsible. The bottom line is, you benefit from long-term savings, protection from rising energy costs, increased resale value and improved home comfort.


Verified and Certified Green Home Building

Many builders today are saying they are green, while thinking that just incorporating several obvious energy features makes their construction green. With the help of our Eco Smart program, Coventry Homes is the first volume builder to receive GREEN certification based on the Environments For Living (EFL) program. EFL is a recognized green building certification system, providing third-party assurance that a home, building or community was created and constructed with strategies that target performance improvement in all the most important environmental metrics: efficient water usage, energy savings, better quality of the inside air, CO2 emission reduction, and stewardship of resources and sensitivity to their impacts. This allows us to construct an energy conservative home that is also responsible and easy on the environment.

Coventry’s Eco Smart homes deliver occupants with an indoor environment that is healthier, more cost efficient to operate and maintain, uses fewer natural resources and is inspected by third parties to ensure performance. In summary, we construct a CLEANER, HEALTHIER, MORE COST EFFICIENT home for you and your family.

Blower Door Test

We also analyze your home for air leaks using a third-party Blower Door Test. Did you know that more than 30% of a home’s heat loss is due to air leakages?

HVAC Unit and Duct Sizing

We look for every opportunity to incorporate energy efficiency into each of our homes because we know it will result in a quality, energy efficient and healthy home. That’s why each home in our Eco Smart Program has its own AC/Heating blueprint based on the number and size of windows, size of home, and other energy efficiency components such as insulation, ventilation and equipment efficiency ratings. Based on all components working together as a system, we properly size the HVAC equipment using the acceptable industry standard Manual J according to the Air Conditioning Contractors of America and EPA standards.

Water Efficiency PEX Plumbing System

Your home features water efficient fixtures and a PEX plumbing system with manifold configuration that dedicates hot water lines to bathrooms to maintain peak efficiency of water usage. In fact, according to a study by the Partnership for Advancing Technology in Housing (PATH), this solution enables hot water to reach the fixtures twice as quickly saving water and energy as compared to copper at any run distance from the hot water heater.

Superior Insulation

16 SEER A/C System

The A/C system has a higher Seasonal Energy Efficiency Ratio (SEER) so it’s more efficient and requires less energy to run.

Air Infiltration

To ensure a healthier indoor environment, we seal all plumbing, electrical and other penetrations of walls and floors as well as joints between building material with polyurethane caulk to reduce air infiltration.

Third Party Energy Inspections

You not only have our word that your home is energy efficient, but the word of an objective third-party too. Outside inspection firms will conduct an inspection of the building envelope for any penetrations to assure your home meets all energy efficiency and quality standards. Finally, every home receives a third party final inspection to ensure that the critical HERS Index has been met.
