By Megan Bagdonas STAFF WRITER Working up a sweat for a good cause Wednesday, more than 40 volunteers from local Lowe’s hardware stores put the finishing touches on a group home for developmentally disabled men in Torrance. “I came to the house last year just to give them an estimate on the flooring and appliances when the residents showed up, and that was that,” said Gus Wahhab, store manager of Lowe’s in Torrance. By sunset, the home would have a freshly painted backyard wall, a gravel walkway, storage cabinets and a new sprinkler system to water all the grass, new flowers and shrubbery. “We’ve just been waiting for these last steps before we could move the boys in,” said Tom Mullen, who helped found STAR in 1973 after his son, who was born handicapped, died at the age of 2. “All of this is a memorial to him.” Mullen said that, while many charities tout how many people they serve, STAR is more focused on providing quality long-term care. “We can only serve a small number, but we’re like family,” said Mullen, who still refers to the male residents as “boys” – even though some are in their 40s – because he’s known them since they were teens. Amid the construction chaos, the “boys” who would be moving in arrived and began excitedly checking out their new rooms. “I’m going to put my computer here and my bed here and my TV here and my dresser right here next to the closet so all my clothes will be together,” said Tommy O’Brien, 52, who has been living in a house STAR rented during the construction. “I want to have a little office in here so I can e-mail my friend in Chicago right away.” Meanwhile, Larry Robbins, 32, got a good look at the spiffy new bathroom with two sinks. “I’ll be cleaning it,” he said. “That’s my chore.” Some residents have autism, others have Down syndrome, but they all share a desire to work and live in normal society. Many of the male and female residents who are able to work find jobs in mailrooms, recycling plants and cafeterias. “They deserve a place in society just like everyone else,” Wahhab said. “But they need someone to stand up for them, and I wanted to be their voice.” Bebe Manganello, a longtime supporter of STAR, went room to room looking at what her donations helped build. “You know that when you give money, you are donating to help mankind,” she said. “But it’s when you see something like this with your own eyes that you really know that it’s going to a good cause.” [email protected] local news?Sign up for the Localist and stay informed Something went wrong.

You’re all set! “Their smiles were so sincere and they were so full of love and they just wanted to give love.” Wahhab gave the nonprofit STAR (Society to Aid the Retarded) a deal on the flooring and appliances, but he didn’t stop there. He got eight Lowe’s stores from the region to select the group home for the company’s “Heroes Award,” which supplied $25,000 in supplies and labor. STAR operates two group homes in Torrance – one for women and one for men. However, five years ago, the men’s home was found to have structural damage and wasn’t handicap accessible, so it had to be torn down and rebuilt. Skyrocketing construction costs slowed down the home’s progress. In the fashion of the TV show “Extreme Makeover: Home Edition,” truckloads of workers carrying shovels, sod, gravel and pipes descended upon the seven- bedroom, three-bathroom house in the 22000 block of Evalyn Avenue and got to digging.

MISSION HILLS – Two employees at a Mission Hills supermarket were tied up and pistol-whipped today during a robbery attempt that failed because the safe could not be opened, police said. The incident occurred at the Albertson’s store at 16201 San Fernando Mission Boulevard, near Woodley Avenue, about 1 a.m., said Sgt. Steve Carmona of the Los Angeles Police Department’s Mission Station. Two masked gunmen entered through the rear of the closed store as it was being stocked and tied up two employees, Carmona said. The gunmen pistol-whipped the employees and demanded the safe be opened, but apparently no one in the store was capable of opening it, he said. The victims suffered minor injuries and were treated at the scene, Carmona said. The would-be robbers fled the store empty-handed, he said. ———————————————- For the latest news and observations on crime in Los Angeles and the San Fernando Valley, check out the Daily News’ crime blog by clicking here.
Share Facebook Twitter Google + LinkedIn Pinterest By Matt ReeseCalvin Peterson — the sixth generation on the Ohio Historic Family Farm in Ross County — can still remember when the back of his beautiful brick house became the front.“The house was built facing Rt. 11 down a long lane. U.S. 35 came through in 1935 near the back of the house, so now the back of the house faces the road,” Calvin said.Incidentally, U.S. 35 has since been moved and turned into a four-lane highway and now the Peterson house sits on Old U.S. 35. The house was built more than 100 years before Old U.S. 35 — making the house really old, but meticulously cared for and well preserved.The Peterson family was among the very first to put down deep agricultural roots in northern Ross County. John Martin Peterson was born in Hardy County, Va. He was the son of Jacob and Sarah Peterson who sailed from Switzerland to America in 1736. John Martin served in the Revolutionary War with the Virginia Militia and, according to A Standard History of Ross County, “was a famous hunter and frontiersman. He and his three younger step-sisters were captured by Indians. He was a prisoner six months when he made his escape.”His son John, in October of 1806, then was among the earliest settlers and the first of the Peterson family in the Chillicothe area, moving there in October of 1806. John was a blacksmith and gunsmith by trade who purchased a tract of land, built a log house and started a farm. In 1817, John moved to Greene County, Ohio and left the farm to his son, Martin, who served as a colonel in the War of 1812. Martin was also part of a group who brought the first Shorthorn cattle over from England to improveThis is the back of the house now, but when it was built, this side of the beautiful brick home was the front facing the road down a very long lane.beef genetics. In addition, he built the beautiful (and now backwards) brick house.“Martin Peterson bought a tract of choice land on the north side of Paint Creek in Concord Township. He was somewhat of a genius and a man of original enterprise. On his land he established a factory for the making of farm implements and wagons, and while conducting the factory he also superintended the clearing of a large tract of land. For many years he and his family lived in a log house, but in 1832 he erected a substantial brick building which with some enlargement and modifications is still standing,” from Portrait and Biographical Record of the Scioto Valley, Ohio written in 1894.The significant family acreage went to Martin’s son, Albert C. Peterson, who was born in 1836 and spent his life on the family farm. He was known as a wealthy and influential farmer of Ross County. The farm grew substantially in his, and subsequent, generations, passing through the ownership of Russell Peterson and Albert F. Peterson, Calvin’s father.“My first job on the farm was with the garden with my mother and dad. During the second World War, all of our hired help was drafted so I was on the tractor at 11 or 12 working the farm with my brother and my uncle. They still had this barn that could house four teams of horses. They had two teams when I was growing up for hauling silage and corn. I remember driving a team of horses, but I was brought up with a tractor,” Calvin said. “They got the first tractor here in the late 20s and the first one I remember was an Farmall M when I was 10.”Calvin’s family moved to the big brick house when he was very young.“I moved to this house in 1932 and they put in a furnace in 1935. Until then they had a fireplace in each room and we carried wood and coal in and hugged the fire. I was quite young when we got electric in the mid-30s. I was only four but I remember when we got the indoor plumbing and the coal furnace. We had a coal bin and my father would go down and get the clinkers out and stoke the fire. We could see our breath upstairs and we would run downstairs to get dressed in the morning,” Calvin said. “They had hogs and cattle and we butchered right here on the farm. We’d put it in salt to cure it and then we had the gardens and the women would can it for the winter. We had a hen house and were self-sufficient.”The farm was very diverse in those days.“I had a brother and we did all the boy things early. I’d play down at the creek in the sand and come when they would ring the dinner bell. There was always something to do. They sold milk in the mid-30s. The dairy was at my uncle’s place and my brother and I would milk twice a day. Every day we’d get up in the morning and go feed the cows and break the ice so they could drink. Then we’d gather the eggs too when I was young. I remember my kindergarten class came out to see the turkeys and the broilers and that was a big thing,” Calvin said. “When they would harvest the wheat in July, they’d cut the wheat and put it in sheaves and stack it and then thresh it. It would take three days, maybe, to thresh here. A neighbor would travel to 11 places with his thresher. The corn picker came along in the early 40s and that was a blessing. It was all done by hand before that. They would put the corn in a pile and then save the fodder for bedding. It was slow.”Every aspect of life required significant effort back in those days on the farm.“There were three dug wells on this farm and they each had a hand pump. We also had windmills with water tanks for the cattle,” Calvin said. “We’d have to go from school to dark working and we worked hard all summer putting hay up. We grew corn, wheat and soybeans and hay for the livestock. We did the hay with a team of horses and a sickle mower with a five-foot blade. They’d cut the hay down and it would cure for two or three days. We had a horse drawn hay rake to put it in a windrow and then they would throw it on a wagon by hand. Then we got a hay loader that would hook on in back of the wagon.”The family’s seed company was also an important part of the farm as Calvin got older.“My father and uncle were involved with Ohio Certified Seed and they raised it here and processed it,” Calvin said. “They started it in the 30s and sold 90% of it here at the farm and I delivered. My dad and uncle bought the elevator in Frankfort and I delivered seed in the bag to Waverly, Jackson, Chillicothe and Portsmouth. My dad and uncle did a good job and were well known for it. They did that into the 60s.”The farm continued to evolve as Calvin grew up.“I went to Ohio State for two quarters. I liked the dirt and I didn’t particularly like school. On Fridays, I would catch city buses to Route 62. Then I would thumb my way back. Back then I didn’t have much trouble getting a ride,” Calvin said. “I was ready to farm and I’d met the girl I wanted to marry at the Ross County Fair. We were married and were blessed with three children. She was a farm girl too. We worked hard from daylight to dark but we had a good marriage for 59 years.”Calvin’s son, John, grew up with the family tradition as well.“I started plowing when I was around 12 and I could reach the petals. Mom would plow during the day and when I got home from school I’d take over,” John said. “We had a three-bottom plow and we could do about an acre an hour. Then I started cultivating with a two-row cultivator John Deere A with a hand clutch.”John now owns the property and his son, Justin Peterson, is the eighth generation to grow up on the farm. Justin’s son, when he visits grandpa and grandma, is the ninth generation of Petersons on the land. Justin and John spent many hours researching the farm’s history to apply for an Ohio Historic Family Farm designation. It seems fitting that the generations who have lived in the very old house backing up to a not quite as Old U.S. 35 have worked so hard to preserve the rich heritage of the farm by looking backwards at the history of their forefathers on the land.“It is a great thing to be able to learn where you come from and the trials, hardships and joys of living on a farm,” Justin said. “There is a lot to learn about the role our ancestors played in shaping the state and this country. There is a lot of history here.”
Jordan Garrow is getting ready to build a new house in New York State, on the cusp between Climate Zones 5 and 6, and he’s planning to heat and cool it with a ground-source heat pump. His contractor wants to install a horizontal “slinky loop” heat exchanger, one of several possible options, and Garrow is seeking a second opinion.A heat load calculation for the house specifies a 4-ton system (one with a capacity of 48,000 Btu/hour), but the contractor wants the heat exchange loops designed as if they were serving a 6-ton system.“His plan is to do a 6-ton horizontal slinky loop field with a 4-ton heat pump,” Garrow writes in Q&A post at GreenBuildingAdvisor. “He claims that an oversized slinky loop field performs the best. However, I’ve heard bad things about slinky loops, and slinky is the only kind of loop they do.”It doesn’t seem either efficient or cost-effective to overbuild the field, since that represents a major part of the system’s cost. He’s sought another quote for a horizontal loop using straight lines, as well as a vertical closed-loop heat exchanger, which would be placed in a well. But the local geology is something of a concern.“I’m worried about the vertical [method] since there is a lot of shale in my area,” he adds, “and I’m not sure how deep the wells could go.” Heat Pumps: The BasicsIs a Ground-Source Heat Pump a Renewable Energy System?Are Affordable Ground-Source Heat Pumps On the Horizon?Air-Source of Ground-Source Heat Pump?Ground-Source Heat Pumps, Part 1: The BasicsGround-Source Heat Pumps, Part 2Ground-Source Heat Pumps, Part 3 Our expert’s opinionHere’s what GBA technical director Peter Yost had to say:You all know that I am not nearly as comfortable taking the lead on mechanical systems as I am with questions about building enclosures. So I went to one of my go-to mechanical system experts, Dan Cautley at SeventhWave. Here is a summary of his perspective based on his personal experience with GSHP systems over the years, plus discussions with some key colleagues, and some web research conducted by Dan and me:Oversizing the slinky heat exchange loop: General agreement here that this is not a bad idea.Design load of the system: Also, pretty good agreement that sure seems as though more effort and resources should be directed to a better enclosure.System guidance: There is a good resource specifically on slinky GSHP systems produced by the International Ground Source Heat Pump Association (IGSHPA) as well as a useful YouTube video about the importance of the quality of the loop installation.Dan found and looked over this resource: An Experimental Performance Comparison between Different Shallow Ground Heat Exchangers and found it useful and reasonable. Note that the slinky systems performed better than the “snail” configuration. And one of Dan’s colleagues added that there are now horizontal boring capabilities that eliminate trenching. (See an image from the report below.)Consider other systems: Dan and his colleagues at SeventhWave agreed that it is just good practice to consider other high-performance systems as well as GSHP. For cold climates, the new fleet of cold climate air-source minisplit heat pump systems has really changed this comparison. Consider another type of heating systemDick Russell selected a ground-source heat pump for his house five years ago and, all things considered, likes it. He not only gets air conditioning from the same system in the summer, but maintenance costs have been very low.“I still feel that it was the right choice for my house,” he says, “but that is because the house is superinsulated and the unit is slightly oversized at 2 tons, so that the two-stage unit never has to upstage past first.”A well drilled for the domestic water supply also was adequate for the heat pump’s heat exchanger, which helped control costs. But Russell thinks that Garrow is facing a more difficult problem.“If your house needs a 4-ton unit, and it can’t use a well drilled for domestic water use, then GSHP would be a harder sell, and you might well be better off with the lower installed cost of minisplit [air-source heat pump],” Russell says.Also, Russell adds, Garrow really ought to put more money into the shell of his new house. “Four tons for a house suggests a house just built to code,” he says. “If my house of close to 4,000 square feet is heated well with a 2-ton unit running in just first stage, you perhaps can cut your heat loss in half, and wind up with a more comfortable house that needs a much smaller heating system. Put your first money into the shell design, rather than try to find a cheap source of heat to dump into it.” As a point of reference, the 2,500-square-foot house will have 2×6 walls with fiberglass batt insulation plus R-10 of rigid foam insulation installed over that. In the attic, he’s planning on 18 inches of blown-in cellulose.How should Garrow proceed? That’s the topic for this Q&A Spotlight. Oversized slinky option may not be a bad ideaThe contractor may have a good reason for recommending an oversized field, says Andrew Bater. Over the course of a winter, a slinky system might have trouble keeping up with demand as the ground around the tubing gets colder and colder.“Anecdotally I understand that some slinky systems underperform as the winter goes on,” he says. “The ground around your slinky (or my well) gets colder and colder and the geothermal unit works harder and harder come the end of February or so. I have even heard tales of systems that quit working altogether after a particularly cold winter.“Surprise, the ground is not always the nice 50Ëš that the marketing literature would imply,” Bater continues. “Look for discussion on the anticipated ‘Seasonal Performance Factor’ for your system as a key to understanding this. Upsizing from a 4-ton slinky to a 6-ton slinky may be a way your contractor hopes to avoid this problem.”Further, says Mel Tillyard, putting in a larger field may not cost a lot more money. Tillyard installed a slinky system because it was cheaper than the alternatives, and the property was already torn up.“They installed the slinky field and rough graded the land in a day,” he says. “I’m not not sure an oversized field will really add much to the cost.”Slinky loops require more power for pumping than do other options, says Charlie Sullivan, although plumbing sections in parallel instead of in series can help. “Oversizing the loop is a better idea than oversizing the heat pump,” he adds. “Oversizing the heat pump will lower your efficiency, but oversizing the loop will improve the efficiency. If they are used to oversizing the heat pump, and matching the loop to the heat pump rather than the real load, you might actually do well to have a loop sized for, say, 3 tons even if your load is only 2 tons.“Despite all that,” he continues. “it’s probably more economical to the money into the envelope and PV and use minisplits.” RELATED ARTICLES The numbers don’t add upDana Dorsett thinks the heating load has been miscalculated. “A better-than-code 2,500 square foot house would not have anywhere near 4 tons of heating load,” he writes. “I’ll bet it’s closer to 2 tons. My 1920s 2×4 antique with 2,400 square feet of conditioned space above grade plus 1,500 square feet of insulated conditioned basement doesn’t even have a 4 ton load until it’s -15ËšF outside.“Your load is clearly going to come in quite a bit lower than mine even if you have 2,500 square feet of basement. (Is this a 1-story?),” he continues. “The calculated heat load is complete junk — even code-minimum houses that size won’t have a 4-ton load at -5ËšF or whatever your outside design temperature.”Russell also thinks that the heat load calculation looks fishy. Before putting in his heating system, Russell did his own heat-loss calculations and then solicited proposals from a number of heating contractors to see what they had to say. Their proposals included a number of errors, including erroneous assumptions about the existence of a fireplace and underestimating the amount of insulation he planned to use.“I could only conclude that too many assumptions and incorrect numbers had been used in the installer’s calculations,” Russell said. “Perhaps that approach would work well with older houses or even one just built to barely meet code. I am convinced that a heat loss calculation for a high-performance house must be highly detailed, taking a considerable amount of time, probably more than a contractor can afford to sink into a quote, considering he may not get the job.”In the end, Russell ordered a 2-ton unit rather than the 5-ton unit the installers were recommending. Build a better boxDorsett is with Russell in recommending that Garrow put more money into insulation.For starters, the R-29 that Garrow thinks he’ll get from his planned wall assembly is wishful thinking. Actual performance will be lower because of the thermal bridging through the wood framing, plus a slight loss in R-value from compressing the fiberglass batts. In reality, the R-19 batts plus 2 inches of extruded polystyrene (XPS) foam will yield a whole-wall R-value of R-24.5, not R-29. Using rock wool batts instead of fiberglass, as well as advanced framing techniques, might get the wall to R-28, he adds, “but that’s about it.”If Garrow is really interested in hitting net-zero energy performance in that climate zone, he’ll need whole-wall R-values of R-30 to R-35, requiring up to 3 inches of polyiso insulation on the exterior. He refers Garrow to a Building Science Corporation research paper on high R-value enclosures for high-performance houses.An insulated concrete form foundation made with expanded polystyrene (EPS), combined with an extra layer of EPS, would make a more attractive option. If nothing else, EPS and polyio use a blowing agent that’s much more environmentally benign than what’s used to manufacture XPS, Dorsett says.
It’s wintertime in the Northern hemisphere, and that means we’re heating our homes. The new year started off a bit on the warm side here in the Atlanta area, with the temperature at nearly 70°F (21°C). In terms of heating degree days (HDD), we began with a mere 2.5 HDD on New Year’s Day and hit 30+ HDD/day only twice in January. Our total for the month was 616 HDD, below our average of 692 HDD for the previous 11 Januarys, so it’s another down year for heating degree days here, despite the Polar Vortex. Still, with temperatures here dropping into the low 20s Fahrenheit some nights, we’ve had plenty of demand for heating in the Atlanta area. And nearly all of that heating has come from one of these three sources. Combustion This one’s common in many places that do significant heating. It’s the furnace that extracts the heat from burning natural gas or propane, the boiler burning natural gas or fuel oil, and woodstoves burning wood. Fuels like natural gas (which is mostly methane), propane, fuel oil, and wood contain chemical energy. The process of combustion releases that energy in the form of heat. Then the heat is distributed through the living space with air ducts and hydronic tubes.RELATED ARTICLESAll About Furnaces and Duct SystemsAre Affordable Ground-Source Heat Pumps On the Horizon?GBA Prime Sneak Peek: Reassessing Passive Solar Design PrinciplesAll About Wood StovesAll About Indoor Air Quality A furnace or boiler sends a fuel through a burner to turn chemical energy into heat. [Image credit: Energy Vanguard]Burning a fuel and using the heat in your home will be less than 100% efficient. Furnaces, boilers, and woodstoves send exhaust gases up the flue and some of heat of combustion goes right out of the house along with the exhaust. If you’re a clever person, though, you may be thinking to yourself, “Hold on a minute, Allison. What about unvented space heaters or ventless gas fireplaces inside the living space?” Every BTU of heat stays in the home as there’s no flue to carry away the exhaust gases. Right? Not so fast. Actually, a 96% efficient condensing furnace is more efficient than a ventless gas fireplace. The key to understanding that lies in the water vapor created during the chemical reaction of combustion. See my article on the topic for more detail. But let’s also remember that unvented space heaters of any kind, including ventless gas fireplaces, are a bad idea. Pretty much anyone who understands indoor air quality will tell you they can be a problem even when operating properly because of the water vapor and nitrogen dioxide created, not to mention the possibility of carbon monoxide when they’re not operating properly. In the type of combustion system that has a flue for the exhaust gases, you’ll always lose some heat to the outdoors and thus your efficiency will be less than 100%. The best furnaces and boilers these days are up in the high 90s, though, so you can capture most of that heat. But that doesn’t count what you might lose in distributing that heat if your air ducts or hydronic tubes are not completely in conditioned space. Electric resistance Another way to get heat is to move electricity through a type of conductor that has a high electrical resistance. That converts the electricity to heat… and it does so at 100% efficiency. Don’t get too excited about that, though, because the third method below gets more than 100%. Electric resistance heat strip in a heat pump or electric furnace. [Image credit: Energy Vanguard]A lot of homes have electric resistance heat (also called strip heat) built into the central forced air HVAC system. That’s the case in the photo directly above. If it’s used as supplemental heat in a heat pump, it can be OK. If it’s your primary source of heat, your heating bills will be higher than you could be paying because you could get much more heat from that same electricity in a heat pump. Sometimes that electric resistance heat in a system malfunctions, too. The worst is when it comes on while your air conditioner is running in summer. Not only will your bills be way too high but you may have trouble cooling the house. By the way, the dog in the lead photo of this article is sitting in front of an “Amish fireplace,” which is nothing more than a glorified strip heater with a blower. Outdoor air, ground, or water The best way to heat your home is by capturing heat from the outdoor air, ground, or water. (Yes, I do have an opinion.) You may be thinking, how the heck can you get heat from cold outdoor air? Great question! It’s basic physics. The second law of thermodynamics says that heat flows from warmer objects to cooler objects. If you want to wring heat out of air that’s 20° F, say, you need to have something colder than 20° F in contact with the air. And that’s what heat pumps do. The outdoor unit of an air-source heat pump extracts heat from cold outdoor air. [Image credit: Energy Vanguard]Regarding efficiency, electric resistance gives you one BTU of heat out for each BTU of electricity you put in. (Yeah, electrical energy is measured in kilowatt-hours but both are units of energy and the conversion is straightforward.) With a heat pump, you generally get more than one BTU out for each BTU in. The ratio of BTUs out to BTUs in is typically around 2 or 3 but can be higher with better heat pumps or lower in really cold weather. Heat pumps do have the drawback of their heating capacity going down as the temperature goes down, and that’s what you need supplemental heat for. As mentioned above, electric resistance is often used as the supplemental heat source in heat pumps but it’s not your only option. A hydronic coil connected to the water heater can be a really good way to provide that extra heat you need on the cold nights. Also, the technology now is much better than it was in decades past. Inverter-driven mini-split heat pumps can provide their full heating capacity down to the single digits Fahrenheit. We’ve got Mitsubishi mini-split heat pumps in our office in Decatur, Georgia, and they’ve been great, even on those days where the temperature has dipped into the 20s. (Disclosure: Mitsubishi is an advertiser in the Energy Vanguard blog.) Another three sources of heat, on a larger scale I wrote that part above about the three main sources of heat in an article a couple of weeks ago and had to follow it up with another article. That’s because my Idahoan friend Skylar Swinford pointed out on Twitter that in high-performance homes the above three can be grouped together as one of three other sources of heating. Skylar Swinford’s three sources of heat for high-performance homes. Skylar spends his days modeling Passive House projects and in that world, where you go above and beyond with the building enclosure, internal and solar gains are definitely more of a factor. Solar gains still have the problem of occurring during the day whereas peak heating loads normally happen in the dark of night, and they can cause problems with overheating if the designer isn’t careful. But internal gains are there for you through the night. The diagram he posted above isn’t from a real house, though. Typically, Passive House projects still get more than half of their heat from the active heating source, which would be one of the three I discussed in the other article. Just to spell it out for the people looking for the list here, the three heating sources for high-performance homes are: Active heating Internal gains Solar gains This discussion has reminded me of reading Amory Lovins discuss the high-performance home he built in Snowmass, Colorado way back in 1984. I don’t remember which book it was but somewhere he wrote about welcoming people — and their 120 watts* of heat — to his home. As you build a house that’s really good at not losing heat, those internal gains become more and more significant. Two notes about solar heating First, high-performance homes indeed can get more of their heat from solar energy. But what seems to be happening more and more often is that superinsulated homes end up overheating because of solar gains. Once you improve the building enclosure with more insulation and really good airtightness, heat from internal gains and active heating sources stays inside. On a sunny day, the extra heat coming through the windows can then be too much. Second, back in the ’70s, solar heating was really a thing. Here’s a cool solar home built in the early ’70s by architect Richard Levine, and which he still lives in. I got to visit him there a few years ago and I can tell you, it’s quite the spectacle. Richard Levine in front of his active and passive solar house built in the 1970s (Image by Energy Vanguard) But focusing a building’s design on capturing solar radiation for heat turned out to be mostly a deadend. As Martin Holladay has shown, superinsulation won the battle between more windows or more insulation. Now we know it’s better to use that solar radiation to make electricity. In the end, if you’re wondering where the heat in your home comes from, it’s almost certainly one of the three active sources: combustion, electric resistance, or the outdoor air, ground, or water. If you live in a high-performance home, you may get a significant portion of your heat from internal gains or solar energy, but the active heating source is still likely to provide more than half of your heat. * I don’t recall exactly what number he used. It may have been 150 W. Allison Bailes of Decatur, Georgia, is a speaker, writer, building science consultant, and the author of the Energy Vanguard Blog.
