BEGIN YOUR HOME ENERGY REVIEW
____

MAIN HOME REVIEW
– Replace key location (high-use) bulbs w LED bulbs, bring your bulb to Home Depot, 2700k or 3000k rated bulb light is a pleasant warm color, 5000k is a less desirable color for many people.
– Home entertainment on standby?  Many screens and audio equipment consume power when they look like they’re off.  If there is a handheld remote, the system is consuming power in standby mode.  Put speaker, amplifiers and other devices on power strips so they can be easily shut down when unused.
– Set-top box in the spare bedroom, turn off with a power strip.
– Have an older, unused VCR, unplug it.
– Check your utility rate plan; log into the PG&E web site or call them.  Utilities have a rate comparison tool so you’ll know if you’re on the cheapest plan.  PG&E uses smart meter data to tell you exactly how much you would save given your recent consumption patterns.

KITCHEN REVIEW
– See if the refrigerator is older, replace if more than 15 years, newer refrigerators will keep food cold longer, especially in during power shutoffs.
– Move refrigerator away from wall 2-4 inches, clean coils yearly with long brush and vacuum.
– Open your refrigerator, check for fullness, check door seal for tears, keep minimum 80% full.
– Turn off your second refrig, consolidate food into one.

Electric Kettle is Energy Efficient - Fast Boil Too!
Electric Kettle is Energy Efficient – Fast Boil Too!

– Instant hot water at sink? Use a timer or turn off and use microwave or electric tea kettle (the kettle is best, most efficient).
– Check if freezer is old (newer are more efficient) or full, if not full, add container with water to be block of ice.
– Replace halogen bulbs with LED bulbs in cooktop vent, these are easily missed but used often.
– Check air gaps around kitchen ceiling recessed lights (also known as can lights).  Buy replacement lights that seal.
– Do you have a second wine cooler with only a few bottles? If yes, consolidate, turn it on only for parties or events in your home, then off the next day.

WATER HEATING REVIEW

Water Too Hot at Your Sink - Lower the Dial Temperature!
Water Too Hot at Your Sink – Lower the Dial Temperature!

Water Too Hot at Your Sink – Lower the Dial Temperature!

– Check water heater temperature. Test, go to a sink closest to your water heater, test with your hand under the water.  Is it too hot?  If so, you are overheating (paying for this energy) by mixing in cold water.  The fix is turn down the temperature dial, check shower temp in a few days where it really matters.  Lower it again until slightly hot.

– IMPORTANT: The factory-set standard temperature for most water heaters is 140 degrees F.  The Department of Energy recommends turning down the temperature to 120 degrees to save energy.  Just remember – any setting below 120 degrees increases bacteria growth inside the tank, so you should not set a lower temperature.

Have a Recirculation Pump? Be Sure It's on a Timer!

Have a Recirculation Pump? Be Sure It’s on a Timer!

– Check for a hot water recirculation water pump at your water heater, adjust for heating shower water for morning or evening time.  Install a timer if you don’t have one.

HOME HEATING and AIR CONDITIONING REVIEW
– Do you have radiant baseboard heaters in any rooms? Make sure they are off in summer. Mini-split heater/air conditioner is far more efficient. Let’s talk.
– HVAC (your heating, ventilating and air conditioning system) Do you have cold rooms? Check register vents directing air in one smooth flow, non-tumble or turbulence. Have HVAC technician review.
– HVAC heater needs a setback programmable thermostat.
– HVAC, install clean filter for heating system (change air filter yearly), check if wider (thicker) filter can fit, they are more efficient, buy them from Amazon
– HVAC, cold rooms? Ductwork highly likely has leaks, have contractor reseal with mastic (we’ve learned in a few years, using tape-only deteriorates in time) Run the fan and hand check air flow in register of colder rooms.  If minimal air, have a HVAC tech check your system.  Hire a certified pro for any system changes.

Add Blown Insulation for Walls (and attic space too)
Add Blown Insulation for Walls (and attic space too)

– Attic insulation settles over time, have thickness checked by contractor, add wall and attic insulation if needed along with air sealing.  These are inexpensive fixes.
– We suggest a whole house fan on upper floor to reduce air-conditioning load.
– Anyone cold at night? Use electric bed heating pad (foot area only), they auto off 2-3 hours, use socks, really!
– Is your bathroom floor warmed electrically, turn it off during summer?  Power may need to be turned off at breaker.
– Heated towel rack? Turn off during summer months. May need to be turned off at breaker.

Glass Fireplace Doors Stop Updraft Heat Loss.
Glass Fireplace Doors Stop Updraft Heat Loss.

– Chimneys leak warm air out of the building.  Use glass doors in front, or block air-flow with fireplace insert, POST a “Non-functioning fireplace notice – no fires allowed.”
____

COLD ROOM FIXES
Heating Season Focus – (priority is low-cost first to higher-priced investments)

Our focus here is to optimize your building envelope (exterior walls, ceilings, doors, windows, HVAC ducts), and many times your heating system efficiency which (we have found in our home audit experience) solves the cold room issue. Buying an expensive new heating system or a simple space heater are later recommendations after all the items below have been reviewed first.

– Weatherstrip doors to the outside, be sure pet door closes fully.
– Close fireplace damper (or install a fireplace balloon if not used), close existing fireplace doors or have glass doors installed.
– Install heavy drapes to keep cold window air away from room.
– Install or adjust directional vents to direct air to the cold areas of the room.

Leaky Air Ducts Waste Your Money
Leaky Air Ducts Waste Your Money

– Have your HVAC ductwork sealed (notoriously leaky) and air balance tested/adjusted by a professional.
– Check/add insulation in attic (be sure to air seal first), then insulate walls.
– Windows replace with double pane energy efficient glass.
– Buy auxiliary mini-split heat pump system, outside install (inside units are louder and have a condensate tray to clean).
– Buy resistance oil-filled heater (last priority – upfront cost is low, but electricity energy dollars are high).
Caulking Air Gap Sealant– Caulk window trim outside to seal air leakage gaps.  DAP Dynaflex 230 works quite well – available at Home Depot stores.

HOUSE TOO HOT IN THE SUMMER?  HERE ARE SOME FIXES.
If the summer heat is too much, here are some actions that will cool your home.   Your air conditioning system will work less hard cooling your home and you’ll spend less on electricity.
– Outside:
Shade the air conditioning unit located next to your outside wall.
– Building Attic: Install an ac powered or solar gable vent on hot side of home.  Enlarge roof vents for more air flow.  Install awnings on the south and west side of home.  Add thickness to attic insulation, minimum of 12 inches.  Re-seal all ductwork (notorious for leaking); hire a contractor.
air-sealed-ceiling-can-light-1– Building Inside: Install cooler LED bulbs, including bulbs in cooktop vent, most-likely hot halogen bulbs.   Upgrade all ceiling lights to this LED sealed type to greatly reduce air transfer.  2700k color is the warm color and is appealing for most people.
– Larger Suggestions: Install a ridge vent to further cool. Install a radiant barrier (metal foil sheeting in your attic space) to keep the attic cooler.  Hire a contractor.
– Actions: Cook outdoors.

OUTDOOR REVIEW
– Check outdoor lighting use LED bulbs, use a timer.
– Check floodlights, change to LED bulbs.
– Check outdoor fountain pump, use a timer or turn it off, better is unplug and fill basin with river rock for aesthetics.

Pool Pump Timers Save You $$
Pool Pump Timers Save You $$

– Check your pool pumps are on timer, both filter and sweep pumps should be on timers; 3-5 hours max needed to keep pool clean.
– Pool pump, have an electrician wire a variable speed motor, uses less energy.
– Walk the outside, check for any areas of energy and other concerns, such as rodent intrusion, roof wear, rain water mis-direction, etc.

YOU’VE FINISHED YOUR HOME ENERGY REVIEW – NICELY DONE!
(There are many revisions above.  Do note this is a process requiring a few upgrades and weekend projects for you to revise everything.)
____

ELECTRIFICATION OF HOMES – Future is All-Electric Homes
(Here are some pointers when you remodel, buy new appliances and move towards an all-electric home.)

– Driving an EV is a wise use of energy.  A 200+ mile battery car is mature product with a considerable range, a smaller battery EV car is 80 mile.  Buy a used EV for around-town driving.
– Solar panels (PV) can provide electrical generation to home and to a battery, the battery is your backup and for everyday power use at night.
– Batteries can generate and store expensive power during day, use battery power at night.  And, batteries are cleaner than running a gas generator.
– Use an electric leaf blower and other electric garden tools. Have your gardener upgrade to electric.  Our air will be cleaner.

Electric Induction Cooking Has No Gas Fumes in Your Home
Electric Induction Cooking Has No Gas Fumes in Your Home

– An induction cooktop has no burned gases, no nitrous oxide NOX (an unhealthy gas) in home and is much healthier. Gas does not vent completely from a home in many cases.  Here is a user story about cooking with this modern cooktop.
– Check your electrical panel size, 200 amp is ideal for all-electric home, 100 amp allows for only 1-2 larger electric upgrades (such as: EV car charger, heat pump water heater, induction cooktop with electric oven).
– Your water heater will fail in upcoming years, they all wear out.  You can prep for more efficient electric heat pump water heater (HPWH).  Have an electrician wire a 220v circuit to the current gas water heater location. You’ll be ready for an electric HPWH energy-saving upgrade.
– When you do replace your furnace, an electric mini-split heater with air conditioner is a wise choice. A mini-split can also supplement colder areas of your home.
– For a cooler home in summer:  Plant trees to shade your home, plant westerly and southerly locations.
