Planning to purchase or build a new home in Montana?
Montana has a state-wide energy code that governs all new home construction
Many new homes built in the state are reviewed by a building code department for code compliance. But all homes must meet state standards for such things as insulation levels, thermal ratings for windows, and heating appliance performance.
Use the Energy Code Guide to help ensure your new home is comfortable, healthy, and energy code compliant.
These codes are for the homeowner's protection. So talk with your builder and look for the blue Energy Component Label on the electrical panel of your recently completed new home.
The Energy Code Compliance Newsletter offers best practices for code officials, builders, and people in the marketplace for new residential buildings in Montana.
The Montana Residential Energy Code Handbook is guide to complying with the statewide energy code.
What the energy code means for you:
Are you buying or building a new home or remodeling your current home?
Are you a builder or contractor?

How We Use Energy in Our Homes
Energy use is divided into two areas; base load and heating. Heating is the biggest utility expense for most Montana families. Baseload consumption is year-round energy uses like water heating, refrigeration and lighting. Small changes in baseload consumption add up over the entire year.
The EPA offers this interesting website to calculate your Home Energy Yardstick. All you need is a single power bill, which ordinarily shows electricity and natural gas usage over a year's time. Enter your usage and see how you compare to similar sized homes nationally.

Is Your Home Up to code?
Heating your home uses more energy and drains more energy dollars than any other system in your home. Typically, 49 percent of your utility bill goes for heating. No matter what kind of heating system you have in your house, you can save money and increase your comfort by properly maintaining and upgrading your equipment.
Your heating system, like your car, needs regular maintenance to run at peak efficiency. That means scheduling a yearly maintenance visit with a heating contractor to tune-up the system. A licensed contractor will make sure your heating system is operating efficiently and safely. A regular maintenance schedule can also help in identifying problems early.
Select energy-efficient products when you buy new heating equipment.
Your contractor should be able to give you energy fact sheets for different types, models, and designs to help you compare energy usage.
For furnaces, look for high Annual Fuel Utilization Efficiency (AFUE) ratings. The national minimum is 78 percent AFUE, but certain ENERGY STAR models on the market that are rated 95 AFUE and above. ENERGY STAR-qualified models are eligible for the $500 Montana energy conservation credit.
Install an ENERGY STAR programmable thermostat.
Inexpensive and easy to install, programmable thermostats automatically turn down the heat during the weekdays and at night so you do not pay to heat your home when no one is around to appreciate the comfort. Programmable thermostats are easy to operate and allow for your different workday and weekend schedules. These thermostats also qualify for the 25 percent Montana energy conservation tax credit.
THERMOSTAT REPLACEMENT WARNING
Many older homes have room temperature thermostats that contain mercury. To identify, remove the front plate and look for one or more small glass bulbs, known as tilt switches. These contain mercury. Each tilt switch contains roughly three grams of mercury, though there may be as much as six grams. Never dispose of this type of thermostat in the trash or local landfill, because mercury is toxic and can leak out to contaminate our air, water, and soil. To assist home-owners with proper disposal of mercury-containing thermostats, a no-cost collection/recycling program is available to all Montana residents. To determine a drop off location in your area, contact your local county sanitarian.
