| Lighting
Efficiency Retrofit: |
Reduce
energy consumption through the use of high efficiency lighting options. |
| Whole
House Air Filtration: |
Adding
whole house HEPA air filtration systems will filter particles down
to 1 um. |
| Duct
Cleaning Cleaning: |
Clean
out dirty duct systems to remove air contaminants. |
| Duct
Sealing: |
Duct
Leakage causes severe Indoor Air Quality (IAQ) problems, and increase
energy use. The average duct system leaks 30% of conditioned air. |
| Water
Filtration: |
Reverse-osmosis
units for areas with poor water quality, sediment filter & activated
carbon filters for areas such as Marin with better water. |
| Appliance
Replacement: |
Chief
candidates: Replacing top-loading washers to horizontal axis machines
saves cold water, hot water, motor work and drying gas. Older inefficient
refrigeration, dish washers, etc. |
| Insulation: |
Blow-in insulation to bring attics to and effective R-20. Typical
older-home attics are R-10. Fix gaps in existing insulation. |
|
Solar Attic Fan: |
For
homes with attics and cooling loads. |
| Day
Lighting: |
Installing
skylights and solar light tubes to reduce lighting load. |
| Glazing: |
Replace older low efficiency windows with Low-E efficient glazing. |
| Pump
Optimization: |
Installing
correctly sized pumps with timers to manage load, can cut energy
costs by 50%. |
| Flash
Hot Water: |
Tankless
water heaters used 40% less energy, have 30+ year lives and give endless
hot water. |
| Mold
Identification: |
Identify
mold and conducive conditions. Manage moisture and humidity which
is the cause of mold. |
| Whole
house Fan: |
install Air evacuation fan to remove excess heated air. |
| Heating
plant improvement: |
Condensing, 2-zone w/dampers, variable speed fan furnaces
save around 40% of the energy of a 20 year-old unit. |
| AC
Improvement: |
Upgrading condensing units to high efficiency SEER 14 or greater
units. |
| Air
Sealing: |
A blow door / neutral smoke test will reveal areas for sealing, controlling
home infiltration to a balance between IAQ and energy savings |
| Pipe
insulation: |
Insulate hot water pipe and heater to improve efficiency. |
| Photovoltaics:
|
Installation
Design and installation PV systems |
| Electric-to-Gas
Appliance Conversion: |
Washers
& Electric water heaters and possible hot tubs are the primary
targets. |
| Crawlspace
sealing |
Seal
crawlspace to prevent moisture and air infiltration. |
