The Vermont Residential Energy Code of 2015 has quite a bit to say about windows and the glass in the windows. Since this is our State’s official stance/law we thought it might be interesting to let you in on what our state is doing:
- There are specific parameters and specific homes must comply with the law:
- Single and Two-Family dwellings
- Multi Family building that are either 3 stories high or less
- Existing structures that have a renovation and / or an addition.
- Log Homes – they may seem odd but Log Homes are exempt from the Energy Code and do not need to adhere to the requirements.
- Mobile Homes and Trailers are all covered under Federal Legislation
- Window Requirements:
- All windows must have a U-Value of 0.32 or better. (remember we talked about U-Values on Monday of this week, go check it out again.
- Glazed in areas may not exceed 20% of the wall area in the home
- Insulation Values – (remember, we talked about R-Values several times)
- Ceilings – minimum R-49
- Sloped ceilings may have R-30 but only up to 500 SF or 20% of the ceiling areas, whichever is less.
- Exterior Walls – minimum R-25
- Basement walls must have R-20
- Crawl spaces – we will deal with this separately
That is a brief and very not-complete list of what is required. We are passing along this information as the beginning of a conversation.
Also, we would like to let you know that in every case listed above Vermont Modular exceeds and does far better than is required; yes we are very proud of our accomplishments and would love to help you build an Energy Efficient Home.
