Sustainable and Green Initiatives
Many people believe in the importance of sustainability and green initiatives but will never get a chance to build a new home incorporating their beliefs. in this situation the best you can hope for is to focus on making your home energy efficient.
Many live in older homes that are inefficient when it comes to energy efficiency.
The Older House Problem
The typical house built before 1970 typically includes 2×4 wall construction with minimal wall insulation and if lucky has R-19 insulation under in the ceilings. Most of these homes may have changed out their single pane glass windows but many have not.
The problem is that many of these homes are currently using two to three times more energy than today’s more energy efficient homes.
Making your home energy efficient can be done all at once or piece mail – either way many of these items car easy DIY projects.
Making Your Older Home More Energy Efficient
- Perform an Energy Audit
- The first step to making an existing dwelling energy efficient is to conduct an energy audit.Many communities and utility companies offer this service free of cost.
- Have a professional perform a blower-door test to help determine where the worst leaks are
- Replace all the windows with low-E, argon-filled units.
- Add insulation in the attic .

- Fill holes around masonry fireplaces, vent pipes and other obvious openings.
- Insulate all hot-water pipes and add more insulation under the floors, up to R-38, if there is room.
