Energy Saving Home Improvements Presentation


— INSTALLATIONS, HOME BATTERY STORAGE SYSTEMS
AND EV STATIONS. THESE ARE ALL HIGH-EFFICIENCY FIXTURES AND APPLIANCES THAT NOT ONLY SAVE ENERGY BUT THEY HELP REDUCE CARBON EMISSIONS. WE VIEWED THEM AS AN IMPORTANT PART OF OUR
CLIMATE SMART SAN JOSE. SAN JOSE IS A LEADING CITY AND TRYING TO FIGHT GREENHOUSE GAS EMISSIONS IN THE USE OF CARBON. YOU WILL HEAR INCREASING MESSAGING ABOUT SAN JOSE WANTING TO ELECTRIFY DWELLING UNITS AND ENCOURAGING USE OF SOLAR. YOU CAN SEE THE INSTALLATIONS WERE TALKING ABOUT TONIGHT IN THE CARBON FREE LIVING TRAILER. IT’S LOCATED BY THE ROTUNDA AND IT HAS SEVERAL
INSTALLATIONS AND GIVES YOU AN IDEA OF HOW WE CAN ACHIEVE ZERO NET CARBON BUILDINGS.
WITH THAT, WE WILL LEARN SOME THINGS ABOUT HEAT PUMP WATER HEATERS FROM RON DAVIS.
>>Ron Davis: SO, WE WILL TALK ABOUT HEAT PUMP WATER HEATERS. I LIKE TO LOOK AT THEM
LIKE MAGIC WATER HEATERS BECAUSE IT TAKES REFRIGERANT, PULLS WARM AIR OUT OF THE ROOM, WHETHER IT’S THE GARAGE, THE HOUSE OR WHEREVER THE WATER HEATER IS LOCATED. IT TURNS IT INTO HOT WATER. SO, IT WORKS BASICALLY BY USING ELECTRICITY AND PULLS WARM AIR IN AND CHANGING THAT INTO WATER TO MAKE IT HOT. YOU HAVE HOT WATER FROM THAT. HIGHLY EFFICIENT. THE ENERGY COMMISSION IS RECOMMENDING THAT THESE BE PUT IN EVERYWHERE NOW. ACTUALLY, WE WILL BE SEEING MORE AND MORE OF THESE INSTALLED. BECAUSE OF THE HIGH-EFFICIENCY. THE HEAT PUMP WATER HEATER WILL AFFECT THE, IN MOST CASES WILL AFFECT THE ELECTRICAL SUPPLY. IT REQUIRES A 30 AMP CIRCUIT. IT’S A 240 VOLT 30 AMP CIRCUIT THAT WILL HAVE TO BE PULLED FROM THE PANEL THAT WILL TYPICALLY REQUIRE ELECTRICIAN TO COME AND DO THAT WORK FOR YOU. ONE GOOD THING ABOUT HEAT PUMP WATER HEATERS IS THAT YOU ELIMINATE THE FLUE. IT SERVES TO COOL THE SPACE IT IS IN BECAUSE IT PULLS THE HOT AIR OUT OF THE
ROOM. IT IS A DUAL PURPOSE DEVICE. THESE ARE ALLOWED FOR ALTERATIONS WITH SPECIFIC CONDITIONS. IN OTHER WORDS, IF YOU ARE DOING AN ALTERATION TO YOUR PROPERTY, AN ADDITION, A REMODEL AND SO ON, THEY CAN BE INSTALLED IN THAT CASE. ELECTRIFY SAN JOSE HEAT PUMP WATER HEATER INCENTIVE PROGRAM IS COMING SOON. WE ARE GOING TO HAVE A MEETING NEXT WEEK. WE WILL TALK FURTHER ABOUT THAT BUT IT WILL BE AN INCENTIVE PROGRAM THAT WILL PAY A PORTION OF THE COST OF THE WATER HEATER AND POSSIBLY A PANEL – NOT POSSIBLY BUT A PANEL UPGRADE. THAT WILL BE BASED ON INCOME LEVEL. THERE WILL BE DIFFERENT PROGRAMS BASED ON INCOME LEVEL AND ABILITY TO PAY. SOLAR INSTALLATION. NOW WE TURN IT OVER TO BRUCE. WE WILL LET HIM TALK ABOUT SOLAR PANELS.>>Bruce: GOOD EVENING. SO, SOLAR PANELS, SOLAR INSTALLATIONS. WE HAVE LITERALLY SEEN THOUSANDS OF THEM INSTALLED IN SAN JOSE. EXPECT TO SEE THOUSANDS INSTALLED OVER THE NEXT FEW YEARS. IT’S PRETTY COMMONPLACE THESE DAYS TO HAVE SOLAR ON TOP OF YOUR ROOF. SO, WE HAVE A BULLETIN FOR THIS. IT TELLS YOU ABOUT HOW TO GO ABOUT GETTING A PERMIT.
THE PERMITS ARE AVAILABLE ONLINE. IF YOU MEET CERTAIN CONDITIONS IN TERMS OF WEIGHT AND
HEIGHT ABOVE THE ROOF AND SO FORTH. IT’S PRETTY SIMPLE AS A PROCESS TO PULL THE PERMIT. AS LONG AS YOU ARE NOT EXCEEDING THE WEIGHT LIMIT AND THE HEIGHT ABOVE THE ROOF OF 18 INCHES. DEPENDING ON THE SIZE OF YOUR SYSTEM, AGAIN, YOU MIGHT BE REQUIRED TO UPGRADE YOUR ELECTRICAL
SERVICE TO ACCOMMODATE THE UTILITY INTERCONNECTION OF THE OUTPUT OF YOUR SOLAR SYSTEM. IT DEPENDS ON THE SIZE OF THE SOLAR SYSTEM. AND WHAT YOUR EXISTING SERVICE PANEL LOOKS LIKE. WE RECOMMEND YOU
AN HIRE EXPERIENCED CONTRACTORS TO PUT IN YOUR SOLAR INSTALLATION. AGAIN, I SAY THAT
ONLINE YOU CAN SAVE MONEY. IT’S A LITTLE BIT LESS EXPENSIVE TO PULL A PERMIT ONLINE. IT IS EFFICIENT. YOU COULD ALSO SCHEDULE THE INSPECTIONS FOR THESE ONLINE. IF YOU GO 18 INCHES ABOVE THE ROOF, IT WILL BE REQUIRED TO COME IN FOR STRUCTURAL PLAN REVIEW BECAUSE OF THE WIND UPLIFT ISSUE. BECAUSE IT PUTS A REVERSE LOAD ON YOUR ROOF WHEN IT GETS WINDY. ONCE YOU LIFT ABOVE 18 INCHES. YOU WILL HAVE TO BRING THIS IN TO STRUCTURAL PLAN CHECK. ELECTRICAL PLAN REVIEW IS CONDUCTED IN THE FIELD BY THE FIELD INSPECTOR. YOU DO HAVE TO HAVE A COMPLETE SET OF ELECTRICAL PLANS WHEN THE INSPECTOR SHOWS UP WITH CUT SHEETS, CALCULATIONS, AND SO FORTH. NOW, WE ARE MAKING THIS ENERGY ON THE ROOF BUT RIGHT NOW, IF I DONT HAVE SOME KIND OF A STORAGE
SYSTEM, I CAN ONLY USE IT DURING THE DAY. RIGHT? AT NIGHT MY SOLAR PANELS AREN’T DOING
ANYTHING. SO, THIS TECHNOLOGY HAS IMPROVED GREATLY IN THE LAST FEW YEARS. USED TO BE BIG RACKS
OF CAR BATTERIES IN YOUR GARAGE AND NOW THEY HAVE A LOT OF LITHIUM-ION PRODUCTS. MUCH MORE
EFFICIENT. MUCH SMALLER AND SAFER. SO, WE HAVE WAYS TO STORE THIS ENERGY. THESE TWO
PICTURES SHOW TWO DIFFERENT SYSTEMS. THEY LOOK ALMOST THE SAME, DON’T THEY? A BUNCH
OF ELECTRICAL EQUIPMENT ATTACHED TO THE SIDE OF MY HOUSE. WELL, THESE TWO SYSTEMS OPERATE
DIFFERENTLY. WE WILL TALK ABOUT WHICH ONE IS WHICH. HOW THEY STORE ENERGY AND HOW THE ENERGY IS UTILIZED. THEY MAY OR MAY NOT PROVIDE BACKUP POWER DURING AN OUTAGE. SYSTEMS MIGHT BE PROGRAMMED TO SHAVE PEAK RATES DURING PEAK RATE HOURS. THESE SYSTEM ARE PRETTY SOPHISTICATED.
THEY CAN BE USED NOT ONLY TO STORE ENERGY BUT TO BACKUP DURING A POWER OUTAGE AND REDUCE YOUR ELECTRICAL RATES WHEN IN THE SUMMER WHEN I AM RUNNING MY AIR CONDITIONER AND THE RATES GO HIGHER. SO, TWO MOST COMMON TYPES THAT WE SEE ARE HYBRIDS AND AC BATTERIES. A HYBRID
IS ONE THAT IS ASSOCIATED WITH YOUR SOLAR PV INVERTER. THE SAME INVERTER THAT CONVERTS
THE DC CURRENT THAT IS ON YOUR ROOF, TO AC POWER FOR THE USE IN YOUR HOME, CONVERTS THE DC POWER FROM THE BATTERY STORAGE SYSTEM FOR USAGE IN YOUR HOME, AS WELL. IT IS RELATED TO A
SOLAR INVERTER SO THAT INVERTER IS DOING TWO THINGS. THE ADVANTAGE IS THEY ARE
ECONOMICAL AND PRETTY EASY TO INSTALL. THEY CAN BE ADDED TO EXISTING SOLAR SYSTEMS. SOME OF THE DISADVANTAGES ARE, THEY MAY NOT BE ABLE TO – SOME MIGHT NOT BE ABLE TO FUNCTION AS A BACKUP SYSTEM. THEY USUALLY – THESE SYSTEMS ARE USUALLY NOT SUITABLE FOR WHAT
WOULD BE CONSIDERED AN OFF GRID INSTALLATION. THEY USUALLY REQUIRE SOME KIND OF CONNECTION
TO THE UTILITY. ALTERNATING CURRENT BATTERY – THAT BATTERY HAS A BUILT-IN INVERTER. IT PUTS OUT AC CURRENT RIGHT OUT OF THE BATTERY. THESE CAN BE INSTALLED EITHER BY THEMSELVES
– THEY DON’T NEED A PV SYSTEM OR THEY CAN BE INSTALLED IN CONJUNCTION WITH A PV SYSTEM. THE ADVANTAGE, THEY ARE SIMPLE TO INSTALL AND PRETTY EASY TO ADD TO AN EXISTING SYSTEM.
THE SYSTEM CAN BE ADDED ON TO, EXPANDED, IF YOU WILL. AND, THE DISADVANTAGES ARE THAT SOME OF THESE AC BATTERIES ALSO CANNOT FUNCTION AS A COMPLETE BACKUP SUPPLY. AGAIN, THESE ARE REALLY DESIGNED TO HAVE A UTILITY CONNECTION AND NOT TO BE LIKE AN OFF GRID INSTALLATION. THESE DO REQUIRE STRUCTURAL PLAN REVIEWS. BECAUSE THEY ARE QUITE HEAVY. THEY WEIGH ANYWHERE FROM JUST UNDER 300 POUNDS TO UPWARDS OF 900 POUNDS. IT IS DEPENDING ON WHAT BATTERY YOU PICK. SO, THEY ARE HEAVY. WE REQUIRE STRUCTURAL PLAN REVIEW FOR THE ANCHORAGE OF THE BATTERIES IN CASE THERE IS AN EARTHQUAKE. YOU DON’T WANT THIS THING FLYING AROUND IN YOUR GARAGE OR THE SIDE OF YOUR YARD. WE STILL DO THE ELECTRICAL PLAN REVIEW FOR THE SYSTEMS IN THE FIELD. THE FIELD INSPECTOR WILL COME OUT AND DO THE PLAN REVIEW IN THE FIELD. WHEN WE COME OUT
TO DO THE INSPECTION, YOU NEED A COMPLETE SET OF ELECTRICAL PLANS. CUT SHEETS. INSTALLATION INSTRUCTIONS. CALCULATIONS AND SO FORTH. VERY SIMILAR TO SOLAR INSTALLATION. ELECTRIC VEHICLE CHARGING STATIONS. KIND OF THE NEXT LOGICAL THING. I WILL PUT PV ON MY ROOF AND
THE BATTERY ON THE SIDE OF MY HOUSE. I WILL USE THAT TO CHARGE MY CAR. BASICALLY, FOR A SINGLE-FAMILY RESIDENCE, THERE IS TWO TYPES OF BATTERY CHARGING SYSTEMS. THERE IS A LEVEL ONE, THE LEVEL ONE IS BASICALLY WHERE I BRING MY CAR HOME AND I PLUG IT INTO THE 3-PRONG
RECEPTACLE IN MY GARAGE OR LAUNDRY ROOM OR OUTSIDE OF MY HOUSE. IT WILL CHARGE MY CAR.
IT WILL CHARGE IT PRETTY SLOW, RIGHT? THREE TO 5 MILES-PER-HOUR OR SOMETHING LIKE THAT.
NOT TOO FAST OF A CHARGE. IF I JUST BRING THIS HOME AND PLUG IT INTO AN EXISTING RECEPTACLE, I DON’T NEED A PERMIT. IF I INSTALL A NEW RECEPTACLE FOR THIS PURPOSE, I NEED A PERMIT TO INSTALL THAT NEW RECEPTACLE. LEVEL TWO CHARGING SYSTEM. IT IS 240 VOLT. THESE WILL BE 30 AMPS TO 40 AMPS AND ALL THE WAY UP TO 100 AMPS. THERE IS SOME FAST CHARGERS THAT GOES TO 200 AMPS. AS WE HAVE BEEN TALKING ABOUT THESE – IF I PUT THIS EXTRA LOAD ON MY EXISTING MAIN PANEL, I WILL NEED
TO DO A LOAD CALCULATION AND DETERMINE IF MY EXISTING ELECTRICAL PANEL WILL SUPPORT
THE ADDED LOAD OF THESE EV CHARGING STATIONS. SOME ARE ADJUSTABLE. IT CAN BE ADJUSTED FROM 20 TO 100 AMPS. DEPENDING ON WHERE I ADJUST THAT IT IMPACTS THE EXISTING ELECTRICAL SERVICE QUITE A BIT. AGAIN, THESE PERMITS CAN BE PULLED ONLINE. VERY EASILY. WE COME OUT TO DO THE INSPECTION AND NO PLANS ARE REQUIRED. WE WILL ASK FOR A COUPLE OF THINGS.
WE WILL ASK FOR THE INSTALLATION INSTRUCTIONS FOR THE EV CHARGER BECAUSE ALL PRODUCTS HAVE TO BE INSTALLED PER THEIR INSTALLATION INSTRUCTIONS AND ASK FOR A LOAD CALCULATION
IF YOUR SERVICE IS 125 AMPS OR LESS BECAUSE WE WANT TO MAKE SURE THAT YOUR ELECTRICAL SERVICE
HAS THE CAPACITY TO SUPPORT THE ADDED LOAD OF THE EV CHARGING STATION. THERE IS A BULLETIN
FOR THAT ONLINE. BULLETIN 263. IT DESCRIBES THE PROCESS OF PULLING A PERMIT AND THE LOAD CALCULATION. SO, THAT’S IT. IF YOU HAVE QUESTIONS ABOUT THESE ENERGY-SAVING PRODUCTS AND SYSTEMS?>>ARE ALL THOSE INCENTIVE PROGRAMS APPROVED? SO WE CAN TAKE ADVANTAGE OF IT? OR IS IT STILL IN THE PLANNING STAGE? THAT IS MY FIRST QUESTION. SECOND QUESTION IS THAT I HAVE A PERMIT TO REMODEL MY HOUSE. IT’S A MAJOR REMODELING. NOW WE ARE ALL OF A SUDDEN THINKING OF ADDING SOLAR PANEL TO MY HOUSE. DO I NEED A NEW PERMIT OR SINCE THE ROOF – THE SOLAR SYSTEM ALL WILL BE
NEW, WE DON’T NEED TO APPLY FOR A PERMIT.>>YOU STILL NEED A PERMIT FOR THE SOLAR SYSTEM. MOST SOLAR INSTALLERS AREN’T GOING TO WANT TO TAKE ON THE RESPONSIBILITY OF SOME OTHER ASPECT OF CONSTRUCTION. USUALLY THEY WANT YOU TO PULL A SEPARATE PERMIT BECAUSE THEY ONLY WANT TO BE RESPONSIBLE FOR THEIR INSTALLATION.>>I HAVE TWO QUESTIONS ALSO. WITH THE BATTERY, DOES BATTERY HAVE TO BE INSIDE THE GARAGE OR CAN YOU PUT IT OUTSIDE IN THE ENCLOSURE OR SOMETHING LIKE THAT? THE SECOND QUESTION IS, I AM CHANGING MY ROOF SO, IS IT EASIER OR HARDER
– I AM CHANGING MY ROOF TO DO THE SOLAR OR –>>SO, FIRST QUESTION IS, IT CAN THE BATTERY BE MOUNTED INSIDE OR OUTSIDE? THESE BATTERY
SYSTEMS CAN BE MOUNTED INSIDE OR OUTSIDE. JUST BE ADVISED THAT, IF WE ARE MOUNTING THEM
OUTSIDE THERE IS CLEARANCE FOR PROPERTY LINES. IF YOUR DRIVEWAY DOWN THE SIDE OF YOUR HOUSE THEY HAVE TO BE PROTECTED FROM PHYSICAL DAMAGE. BY MOUNTING INSIDE MY GARAGE, AGAIN I HAVE
TO MAKE SURE I MOUNTING IT WHERE IT WILL NOT BE HIT WITH MY CAR WHEN COMING IN AND OUT OF THE GARAGE SO YOU WANT TO TAKE INTO ACCOUNT THE SPATIAL REQUIREMENTS. I THINK THE PERFECT
TIME TO PUT SOLAR ON YOUR HOUSES WHEN YOU’RE DOING A REROOF BECAUSE YOUR SOLAR INSTALLER CAN COORDINATE WITH THE ROOFER AND MAKE THOSE PENETRATIONS REALLY WELL. WHEREAS IF I COME TO AN EXISTING ROOF, NOW I MAKE PENETRATIONS THROUGH MY ROOF INTO AN EXISTING ROOF. YES, WHERE THEY PUT THE SUPPORTS FOR THE SOLAR END. THOSE ATTACHED TO THE STRUCTURE. THEY
GO THROUGH THE ROOF, ACTUALLY. THOSE HAVE TO BE PROPERLY FLASHED.>>I HAVE 200 AMPS SERVICE AND SOLAR PANEL ALREADY IN THE HOUSE. I WOULD LIKE TO GET A 2ND METER.
WOULD I BE ABLE TO SPLIT AT 150 – 50 AMPS OR DOES IT HAVE TO BE EVEN SPLIT? 200 AMP SERVICE
PANEL THAT I ALREADY HAVE.>>WELL, MY FIRST QUESTION WILL BE WHAT IS
A 2ND METER FOR?>>STRICTLY EV CHARGER.
>>FOR AN EV CHARGER.>>YOU ARE ALLOWED BY THE UTILITY TO GET A
SECOND METER FOR AN EV CHARGER. YOU HAVE TO GET APPROVAL FROM THEM FIRST.
>>YES, BUT I DON’T WANT TO LOSE – I NEED AT LEAST 150 AMPS IN THE HOUSE. I DON’T WANT
TO SPLIT AT 100 AND 100. CAN I SPLIT 150 – 50.>>YOU COULD, YES.>>SO, IS NOT UP TO THE PG&E OR UP TO THE CITY?>>YOU’D STILL WANT TO DO A LOAD CALCULATION
TO MAKE SURE THAT YOUR 150 IS SUPPORTING IS YOUR EXISTING RESIDENCE. YOUR
50 WILL SUPPORT YOUR CAR CHARGER. IT WOULD WORK. YOU COULD SPLIT 2 METERS AND PUT IN TWO PANELS. ONE AT 50 FOR THE EV AND ONE FOR THE MAIN RESIDENCE.>>I HAVE A ROOF THAT DOESN’T HAVE A LOT OF SUN ON IT BUT I HAVE A DRIVEWAY THAT HAS A GREAT DEAL OF SUN ON IT AND SO I WAS WONDERING IF I COULD BUILD A STRUCTURE FOR A SOLAR PANEL DOWN MY DRIVEWAY AND NOT
CALL IT AN ADU.>>YES, YOU CAN. NOT GOING TO BE ABLE TO PULL
THE PERMIT ONLINE. YOU CAN BUILD A STANDALONE OR NON-ROOF MOUNTED SOLAR SYSTEM ON A SINGLE-FAMILY RESIDENTIAL PROPERTY. YOU WILL HAVE TO GET PLANNING APPROVAL AND MEET SETBACK REQUIREMENTS AND STRUCTURAL CALCULATIONS FOR IT AND SO FORTH. YOU CAN BUILD A NON-
ROOFTOP – GROUND MOUNTED SOLAR SYSTEM. AS LONG AS YOU HAVE ENOUGH ROOM, YOU CAN GET
THE STRUCTURE DONE FOR IT.>>IS THE SOLAR STORAGE SYSTEM
LIKE A POWER BANK WHERE YOU LIKE CHARGE SOME BANK AND TAKE IT WITH YOU AND YOU CAN CHARGE
YOUR PHONE LATER WITHOUT HAVING TO PLUG IT INTO AN OUTLET?>>SO, WAS THAT QUESTION – CAN I RUN STUFF ON THE SOLAR SYSTEM WITHOUT PLUGGING INTO
AN OUTLET? WAS THAT YOUR QUESTION?>>NO, WHEN IT’S LIKE DARK OR YOU NEED TO
USE THE STORAGE, YOU CAN USE IT WHENEVER YOU WANT WITHOUT HAVING TO HAVE THE SUN OR A LIGHT SOURCE?>>COULD YOU REPEAT THE QUESTION, MIKE?>>HE IS ASKING ABOUT SOLAR SYSTEMS. BEING USED AS A WAY TO USE DEVICES.>>THEN HE IS ASKING ALSO ABOUT THE BATTERY BACKUP SYSTEM.>>SO, YOU CAN – SOME SOLAR INVERTERS COME WITH A RECEPTACLE ON IT SO THAT IF MY POWER
GOES OUT, I CAN PLUG MY REFRIGERATOR OR PHONE OR WHATEVER I WANT INTO IT AND IT WILL JUST
RUN OFF OF SOLAR SO THERE IS SOME INVERTERS THAT COME WITH SOME LIMITED, CALL IT CAPACITY,
SO WHEN THE UTILITY DISCONNECTS BUT IT’S ONLY GOOD DURING THE DAY. IT WILL NOT WORK AT NIGHT. WHAT WAS THE OTHER QUESTION?>>HOW DOES HE PLAY GAMES?
>>YES, YOU CAN ONLY DO IT DURING THE DAY UNLESS YOU GET A BATTERY AND THEN YOU CAN DO
IT ALL NIGHT.>>SO, IF YOU HAVE THE POWER AND STORAGE IN
THE BATTERY BACKUP, YOU CAN USE IT WITHOUT THE SUN AND LIGHT SOURCES?>>SO, YES, BATTERY CAN WORK WITHOUT THE PV SYSTEM.>>I THINK HE WAS JUST ASKING ABOUT THE BATTERY STORAGE SYSTEM. LIKE, IT STORES THE POWER
FROM DURING THE DAY AND SAY, IT’S NIGHTTIME AND THE POWER GOES OUT, YOU STILL HAVE THAT
BATTERY BACKUP. IS THAT WHAT YOU ARE ASKING. ONE MORE.>>SO, MY QUESTION WAS REGARDING THE HEAT PUMP WATER HEATER. WOULD IT NOT BE BEST TO
INSTALL SOMETHING LIKE THAT AND AN ATTIC WHERE YOU WOULD CAPTURE THE MOST HEAT?>>YES. IT’S RECOMMENDED THEY ARE INSTALLED IN THE HOUSE. THE ATTIC WOULD BE A GREAT
PLACE. AT LEAST IN THE SUMMERTIME TO PICK UP EXCESS HEAT. IN THE WINTER MAYBE NOT SO
MUCH. THAT’S WHY THEY ARE SAYING, THE ENERGY COMMISSION WILL ONLY GIVE CREDIT FOR IT IF
IT’S INSTALLED INDOORS. THAT MEANS IN THE GARAGE OR IN THE HOUSE, NOT – THEY DON’T
TALK ABOUT UNCONDITIONED SPACES. ATTICS, I DON’T THINK ARE PART OF THE ACCEPTANCE PROCESS WITH THAT. IT WOULD HAVE TO BE IN THE HOUSE OR THE GARAGE.>>OKAY. WHAT ABOUT A BASEMENT? IS THAT INCLUDED OR FALL IN TO THE SAME CATEGORY AS AN ATTIC?>>I WOULD THINK A BASEMENT WOULD BE AN OKAY PLACE. I WOULD CALL THAT INDOORS. VERSUS AN
ATTIC. I THINK IT WOULD BE FINE.>>OKAY. WHEN DO YOU ANTICIPATE THE INCENTIVES
COMING OUT?>>YOU KNOW, YOU CAN GO TO THE CLIMATE SMART
TABLE IN THE WING HERE AND TALK TO LEANNA. SHE IS THE ONE THAT WILL BE – IS THAT JULY?
I SHOULD KNOW THAT. THIS GENTLEMAN SAYS JULY THEY WILL BE AVAILABLE. YOU WILL WANT TO APPLY QUICKLY FOR THAT BECAUSE IT IS A LIMITED NUMBER THAT WILL BE AVAILABLE, OKAY?
>>OKAY. THANK YOU.>>GOING ALONG WITH THE SAME QUESTIONS, DO
THESE DEVICES FIGHT THE HEATING SYSTEM OR DO THEY HAVE SHUTOFFS – YOUR CENTRAL HEATING IS GOING AND SO, DOES IT JUST RUN OFF OF STRAIGHT ELECTRICITY AS OPPOSED TO – YEAH.>>I THINK THEY INTERACT. I THINK THEY WORK WITH THOSE. I DON’T THINK YOU’RE TAKING SO MUCH HEAT OUT OF THE ROOM THAT THE ROOM WOULD BECOME COLD.>>I’M JUST THINKING ABOUT IN THE HEATER WINTER.>>I UNDERSTAND WHAT YOU’RE SAYING. I THINK IDEALLY THEY WOULD BE – THEY WILL OBVIOUSLY
NOT SIT IN THE ROOM – LIVING ROOM, BEDROOM. THEY WILL BE IN A CLOSET OR A LAUNDRY ROOM
OR SOMEWHERE LIKE THAT THAT IS PROBABLY NOT HEATED. YOU WILL HAVE AMBIENT HEAT IN THAT
SPACE AND IT WILL PICK UP BUT IT WILL NOT DETRACT FROM THE PERFORMANCE OF THE HEATING SYSTEM.>>THE INCENTIVE FOR YOU GUYS IS FOR US TO NOT USE AS MUCH GAS AND USE ELECTRICITY INSTEAD.>>THAT IS CORRECT. I KNOW IT’S COUNTER INTUITIVE BECAUSE WE HAVE GONE DOWN THE PATH OF USING GAS FOR
EVERYTHING WE COULD AND STAYING AWAY FROM ELECTRICITY ESPECIALLY RESISTANCE HEAT. SO,
WE HAVE REVERSED OUR POSITION ON THAT. THE STATE HAS REVERSED ITS POSITION ON THAT AND
HAS THE CITY. ELECTRICITY IS MORE READILY AVAILABLE NOW. IT IS CHEAPER. ALTHOUGH IT
DOESN’T SEEM CHEAP, IT’S LESS EXPENSIVE. IT’S MORE AVAILABLE BECAUSE OF THE SOLAR PANELS
ON EVERYBODY’S ROOF AND EVERYONE IS TAKING CARE OF THEIR OWN BUILDING AND FEEDING BACK
INTO THE GRID SO THERE IS ACTUALLY ENOUGH ENERGY NOW THAT ELECTRICITY IS A VIABLE ALTERNATIVE AND THE REASON THAT IT’S BEING PROMOTED SO HEAVILY IS THAT WE ARE THEN REDUCING THE CARBON
FOOTPRINT. ELECTRICITY IS OBVIOUSLY CLEANER THAN NATURAL GAS. THAT IS THE BIG REASON.>>IS THERE A KIT TO CONNECT THE HEAT PUMP WATER HEATER TO A HEAT PUMP HEATING/COOLING SYSTEM AT THIS TIME? IS AN INTEGRATED UNIT THAT TAKES ADVANTAGE –?>>THERE IS NOT THIS TIME BUT I’M SURE IT’S COMING. YOU COULD, ESSENTIALLY, HAVE A SEPARATE CONDENSER OUTSIDE. HEAT PUMP CONDENSER THAT YOU WOULD BE ABLE TO RUN TO PICK UP HEAT TO HEAT YOUR HOUSE, HEAT TO HEAT YOUR WATER HEATER. YOU KNOW – THESE PRODUCTS ARE BEING INVENTED AS WE SPEAK RIGHT NOW. THEY ARE BEING TESTED. IN THE FUTURE I BELIEVE THAT WILL BE THE CASE. RIGHT NOW, WITH THE HEAT PUMP HEATING SYSTEM YOU CAN HAVE A CONDENSER AND A WALL UNIT IN EVERY ROOM THAT YOU CAN
CONTROL SEPARATELY SUPER EFFICIENT WAY TO GO. ONCE AGAIN YOU’RE PICKING UP AMBIENT
HEAT OR COOL FROM THE AIR AND USING THAT TO ITS FULLEST POTENTIAL. I THINK IT’S A GREAT WAY
TO GO.>>MY QUESTION IS, I HAVE BEEN OUT THERE ASKING
FOLKS ABOUT THIS. I’M GOING TO PUT SOME SOLAR PANELS UP. I WONDER IF THE STATE AND FEDERAL INCENTIVES
STILL AVAILABLE TO REDUCE THE COST?>>I DON’T KNOW THE ACTUAL ANSWER TO THAT
BECAUSE INCENTIVES KEEP GOING. THEY WILL GO AWAY AND EXTEND THEM FOR ANOTHER THREE YEARS. I THINK YOUR INDIVIDUAL SOLAR INSTALLER COULD TELL YOU WHAT’S AVAILABLE. BOTH FROM THE GOVERNMENT
STANDPOINT AND THE UTILITY STANDPOINT. THE INCENTIVES KIND OF COME AND GO. WE DON’T ACTUALLY KEEP TRACK OF THOSE OR KEEP TRACK OF THE INCENTIVE PROGRAMS. PEOPLE WHO SELL THOSE SYSTEMS SHOULD
BE ABLE TO INFORM YOU OF THOSE INCENTIVE PROGRAMS.>>ON A HEAT PUMP WATER HEATER, IS THAT THREE
OR FOUR WIRE AND 240 VOLT REQUIRED?>>SINGLE PHASE, 240 VOLT FOR A SINGLE-FAMILY RESIDENCE. IT’S TYPICALLY A 240 VOLT AND 30 AMP CIRCUIT.>>IT TAKES FOUR WIRES?
>>CORRECT. TWO-PHASE CONDUCTORS IN A NEUTRAL AND AN EQUIPMENT GROUND.>>Hi. I HAVE A TWO SOLAR SYSTEM ON MY ROOF. ONE IS FOR ELECTRICITY AND ONE IS
FOR THE WATER HEATER. I HAVE TWO TANKS IN THE GARAGE. ONE IS STORAGE. THE OTHER ONE IS A REGULAR
WATER TANK. MY SON WANTS TO GET RID OF THE STORAGE TANK AND THE CAP THE SOLAR SYSTEM THAT HEATS THE WATER HEATER. IS THAT WISE TO DO?>>YOU WERE TALKING ABOUT SOLAR THERMAL SYSTEM WHERE YOU GET HOT WATER FROM THAT SYSTEM. IT MIGHT BE WISE TO DO IF IT’S BEEN UP THERE FOR A LONG TIME BECAUSE THEY LOSE EFFICIENCY. QUITE HONESTLY, THEY ARE NOT VERY EFFICIENT TO BEGIN WITH SO THE LONGER THEY ARE THERE, THE LESS EFFICIENT THEY BECOME. IF YOU ARE STILL GETTING SOME BENEFIT I WOULD NOT DISCONNECT IT BECAUSE IT’S FREE ENERGY. YOU GOT SOLAR PANELS AND YOU’RE GETTING FREE HOT WATER FROM THE THAT. I WOULD NOT DISCONNECT IT UNLESS THERE IS A PROBLEM OR
IT’S LEAKING OR SOMETHING IS WRONG WITH IT I WOULD LEAVE IT AS IS.>>NO, HE JUST WANTS THE SPACE. THE STORAGE TANK IS BIG. IT TOOK THE THE SPACE FOR THE DRYER. AND THE DRYER HAS TO GO TO THE OTHER SIDE OF GARAGE.
>>FOR IT TO WORK PROPERLY THE SOLAR TANK NEEDS TO BE THERE. YOU HAVE TO HAVE A STORAGE
TANK FOR A SOLAR HOT WATER.>>SO YOU WOULD NOT TAKE IT OUT?>>I WOULD LEAVE IT THERE. YOU ARE GETTING A GOOD BENEFIT FROM IT.>>YOU KNOW, THERE ARE INCENTIVES ON HEAT PUMP WATER HEATERS RIGHT NOW. FEDERAL INCENTIVES ON 300 DOLLARS
PER WATER HEATER. SOMETHING I DID NOT MENTION BUT IT IS AVAILABLE CURRENTLY. SOMETHING TO
TAKE ADVANTAGE OF.>>SO, REFERENCING ONE OF THE EARLIER SLIDES
FROM TONIGHT. I NOTICED ON THE SIDE OF THE HOUSE THEY DREW A GEOTHERMAL HEAT PUMP – OH NO, YOU ARE SHAKING YOUR MICROPHONE. THAT’S NOT SOMETHING YOU’RE PREPARED TO TALK ABOUT AT THIS POINT.>>THAT SLIDE WAS REPRESENTATIVE OF MANY TYPES OF SYSTEMS. NOT SOMETHING WE WOULD SEE HERE. GEOTHERMAL IS VERY PROHIBITIVE COST
WISE. IT’S NOT SOMETHING YOU WILL SEE IN A MILD CLIMATE LIKE THIS. IT’S SOMETHING YOU
WOULD DO IF YOU LIVED IN MONTANA AND YOUR FROZEN HALF THE YEAR. YOU WANT TO GET AS MUCH
HEAT AS YOU COULD OUT OF THE GROUND. THAT IS – YEAH. I APOLOGIZE FOR THAT. MY FIRST
COMMENT WHEN I SAW THE SLIDE – IT DOESN’T FIT. YOU’RE THE ONLY ONE THAT CAUGHT IT SO FAR.>>IT SOUNDED COOL BUT NO ONE IS TALKING ABOUT
IT. THANK YOU FOR EXPLAINING.>>OKAY, THAT CONCLUDES THE PRESENTATION FOR
TONIGHT. THANK YOU FOR YOUR INTEREST. SLIDESHOW WILL BE ON THE WEBSITE. THE POWERPOINT ITSELF IS ALREADY ON THE WEBSITE. THE RECORDED VERSION WITH THE SPEAKERS WILL BE UP IN ABOUT ONE
WEEK ON THE WEBSITE. SANJOSECA.GOV/PERMITCENTER.
