Building “Green” has many meanings. The most common interpretations generally refer to building with sustainable construction methods, reducing the carbon footprint during and after construction, and using materials that have a low VOC (Volatile Organic Compound) volume. Seacoast Modular Homes has the following “Green” building options and techniques available, and we are always adding more. If there is something you would like to talk about to make your home more efficient, please call us. We can accommodate most requests, but below are the most common:
- Ground-sourced geothermal heating and cooling systems that will minimize your family’s carbon footprint, reduce your consumption of fossil fuels, provide better comfort, and eliminate your reliance on gas or oil to heat and cool your home. Check out our geothermal brochure for more information.
- All of our homes are built with an incredible amount of emphasis placed on air infiltration. Having our homes built in a factory allows us to create a much tighter thermal envelope, resulting in less Air Changes per Hour (ACH). By reducing the amount of air that is allowed to enter/exit through your walls, we are able to provide more stable heating and cooling at lower costs.
- We offer 10″ double exterior walls systems, filled with dense pack fiberglass insulation. This system nearly eliminates the thermal bridging of a conventional 2×6 wall system. Thermal bridging is when heat transfers from the inside of the wall to the outside, via framing members. By using a double wall the framing members in the walls are separated by 3″, this eliminates over 90% of those thermal bridges. By making the wall 10″ thick, we are able to insulate with almost 2x the amount of insulation a normal wall would have, making for a very efficient wall system. More effective than just using foam insulation.
- We also offer 2″ foam on all of our homes. This foam further reduces air infiltration and thermal bridging. It also adds another R10 to your walls. Combining this with a 10″ double wall will give you an approximate wall rating of R35+. Code is R19.
- Our minimum roof insulation is R49. (Code is R38). We also offer an upgrade to R60 with a special truss design, which is almost 2x the code.
- High Efficiency Window Packages – We offer windows from many different manufacturers with different options and levels of glazing. Some of our windows have triple panes, which make them extremely efficient.
- It is responsible for us to design your home in a way that creates passive savings and optimal thermal performance, based on factors such as your home’s orientation to the sun at various times of the year, landscaping buffers to block wind, and using building materials that increase the efficiency of your home’s thermal envelope.
- Limiting windows is always a good idea as they are a significant source of heat loss in most homes, but we also realize that windows are important. We can help you create a balance that will work for your environmental concerns, as well as your design criteria.
- Many of the materials that are used to build a home can have a varying range of VOCs. To reduce the amount of these VOCs in your new home, we are able to request different materials such as adhesives and sheet goods, and use alternative products (for instance pre-finished flooring has a lower VOC content than floors that are finished with a polyurethane based stain on site. Certain types of sheathing and processed lumber have varying amounts of VOCs, etc…). Some of the VOCs in a home cannot be avoided, and those items can be mitigated by using better construction practices and even with the assistance of added mechanical ventilation to improve air quality.
