Our New Home Construction Methods Create Energy Savings

You can’t read an article online or see an advertisement for a product without it mentioning energy efficiency. In today’s market, buying energy efficient appliances, vehicles, lighting, etc., is an important decision consumers are making when purchasing a product. This is no different when it comes to building a new home – especially in Wisconsin where winters are harsh and summers are hot!

We are constantly working towards building the most energy efficient homes and implementing the latest in technologies to do so. The Demlang Energy Savings System not only reduces energy waste, it also puts money back in your pocket for years to come – on average about $600 in energy savings per year!

Building comfortable, family-friendly homes that cut down on high energy costs.

The Demlang Energy Savings System

Building a house that saves on your electric bill doesn’t have to cost more! The “Demlang Energy Savings System” comes standard with each of our homes, meaning these energy cost savings come standard with your new home! It’s all a part of our “Build Tight, Insulate Right” approach to new home construction. This includes:

Demlang Builder's Energy Savings System

Blower Door Test

To determine just how leaky the house may be, and to locate air leakage locations throughout the home.

Infrared Scanning

By itself and in conjunction with the blower door test, infrared scanning allows us to locate cold spots and air leakage points or insulation flaws in hidden locations.

Hot Water Heater Power Vent Testing

To ensure there is no risk of backdraft and that exhaust gases escape properly, we test the hot water heater vent fan.

HVAC Airflow Testing

We measure supply and return airflows from the furnace (if this is how your home is heated) to ensure that the system is reasonably balanced.

Ventilation System Testing

It is important to recognize that airflows from ventilation equipment can be a large factor in the home’s ability to expel moisture/odors from the home.

Spray Foam Insulation

Creates an air tight seal in nooks and crannies that may be exposed with traditional insulation, we add spray foam in areas like box sills and around windows.

Construction Details

Advanced framing techniques add insulation value to your home while sealing around windows, doors, mechanicals, and other openings ensure a tight build.


Automatically regulates the humidity in your home, helping you control comfort levels leading to more effective heating and cooling.

Ceiling Fan Locations

Electrical packages come standard with fan boxes in many locations throughout the home, allowing you to add ceiling fans where desired.

Certified Third-Party Inspection

Each home is reviewed by a third-party inspector to make sure it meets the highest standards of energy efficiency.
