    Homebuilders want high school students for construction jobs – Sacramento Bee - July 30, 2017 by Mr HomeBuilder

    Sacramento homebuilders are trying to deal with a severe shortage of construction workers by training high school students in summer internships. They want the teens and their parents to consider the possibility that a construction career might be a good alternative to college, though that can require some convincing.

    Theres a negative stereotype about dirty jobs, said Rick Larkey, executive director of the North State Building Industry Foundation. The group is leading the effort to recruit 5,000 new workers over five years in Sacramento, Placer, Yolo and El Dorado counties. A big part of that is the outreach to high-school students through internships and after-school programs.

    The foundations pitch on its website is that a four-year college degree isnt the guarantee of financial success it used to be. The American workforce is in desperate need of skilled technicians, and incomes for construction work can rival jobs requiring four-year degrees without the expense of college.

    Were trying to give them an opportunity to have a successful and meaningful career that pays well, especially for those that like to work with their hands, Larkey said.

    After last decades housing crash, thousands of Sacramento-area construction workers left the industry. Many retrained for new careers or moved away. Now that home construction is on the upswing, builders are finding they cant keep up with demand because they lack skilled laborers. Plumbers, electricians and many other tradespeople are in short supply.

    The builders are looking to teenagers, such as Karina Records, to help fill those jobs.

    Records, 17, spent part of Thursday morning in the attic of a half-built home learning to install heating and air conditioning ducts. She carefully stepped from rafter to rafter with the sun beating down on the roof above her on a 100-degree day.

    My helmet is filled with sweat, she said as she climbed down a ladder to learn how to install a dryer vent. Despite the heat, she said she enjoyed the detailed work of connecting ducts and other tasks involved in heating, ventilation and air conditioning, or HVAC, a field where skilled workers are in high demand.

    Records is an incoming senior at Sheldon High School in the Vineyard area of Sacramento County, about 2 miles from the construction site where shes worked this summer. She and 14 or 15 high school juniors from the Elk Grove Unified School District made $10.50 an hour interning with national homebuilder Lennar at its subdivisions near Bradshaw Road and Gerber Road.

    Under the instruction and guidance of Lennar mentors, the interns have gotten hands-on experience in nearly every step of home construction. They poured foundations, framed houses and put in plumbing. They hung cabinets, laid carpet and installed wiring. They painted homes, built fences and set up solar panels.

    I try to expose them to everything we can so they can make choices, said Sandy Wills,senior construction manager with Lennar at its Vineyard location.

    About 30 interns worked at Lennar job sites around the Sacramento region this summer. More than 30 others took part in Mayor Darrell Steinbergs Thousand Strong initiative, learning construction skills, or another program run through the Placer County Office of Education, the Building Industry Foundation reported.

    The Lennar interns at the Vineyard project said their exposure to different trades was key to learning what work they found satisfying.

    Nick Carlson, 17 and a Sheldon High student, said hed like to be an electrician. The work is challenging, and journeyman electricians make about $35 an hour, or $70,000 a year, he said. Carlson said he sees trade school as a potentially more direct route to a career than college.

    A number of interns said they intended to go to college to pursue a degree in construction management or engineering before going back to work in the homebuilding industry. Others said they were still weighing their options but hadnt ruled out going right into a skilled trade.

    Chris Rhodes, 17, said he learned about the construction internships as a student in Cosumnes Oaks High Schools Architectural Design and Engineering Academy. He said hell probably go to college to study mechanical engineering but liked knowing he had options.

    Construction is a fast-growing industry, Rhodes said. If doors get closed to you, this door is always open.

    Jason Kolvoord, 17, said he wants to work in construction for a while before going to college, and Miriam Bell, 17, said she plans to go to trade school but hasnt decided on a trade yet. Both teens attend Laguna Creek High School.

    Lennars Sacramento-area vice president for operations, Jeff Panasiti, said there are plenty of jobs for interns who want them after graduation.

    You guys are on the other side of the recession, Panasiti told a group of teens in a newly built garage. Seventy percent of construction workers lost their jobs and scattered. Now there are ample opportunities for new workers, he said. The skys the limit.

    How to stop fireplace smoke smells during summer – Daily Herald - July 30, 2017 by Mr HomeBuilder

    Q: How do I stop my wood-burning fireplace from smelling like smoke in humid weather? A faint smoke smell would be OK, but this is obnoxious. It seems worse when the air conditioner or even the washer and dryer are running. The smell just wafts on in from the chimney. We have a glass door installed, but it doesnt help.

    A: Chimney smells stink up indoor air when the air pressure is lower indoors than out. Especially in a house that was built to be fairly airtight, this can happen when a dryer or other exhaust fan runs or if there are leaks in heating and air-conditioning ducts. To equalize the pressure, air moves down the chimney, making your house stink. Summer conditions add to the problem because the outdoor air is hot and humid and therefore heavier than the drier, cooler indoor air.

    In theory, closing the damper on your fireplace should stop the airflow where the air picks up the smell. But fireplace dampers often dont seal very well. For a better seal, you could have a chimney sweep install a spring-loaded stainless-steel damper at the top of the fireplace flue. We called a local company that estimated the job at $630.

    Or, for $42.99 to $86.99, depending on the chimney width, you could install an inflatable device known as a Chimney Balloon, available at Amazon.com. It has mixed reviews, however, with some buyers reporting that it punctures easily. Filling a hefty plastic bag with insulation and stuffing that into the chimney opening at the base of the fireplace might work just as well and would surely cost less. Just be sure to remove the plug before you use the fireplace.

    If closing off the chimney doesnt stop the smell, call a heating and air-conditioning company to assess air balance in your home. It might help to pipe fresh air directly to combustion appliances (which would include the dryer if yours is a gas model). Or you might benefit from a heat-recovery ventilator, which could introduce more fresh air but in a way that uses the temperature of indoor air to preheat or precool it so you dont waste energy. Sealing leaks in heating and air-conditioning ducts or balancing the system by adding more openings might also be part of the solution.

    Q: Our KitchenAid Superba garbage disposal was installed in January 2011. For the past few months, it has failed to grind up and flush vegetable matter that it previously had no problem with. The blades rotate, chopping up the waste, but the waste does not exit the unit. I called the manufacturer for guidance. I was told to fill the disposal with ice to help with grinding. Although some relief was obtained, much of the waste remained in the disposal. Any ideas about why it is failing?

    A: This is a three-fourths-horsepower model thats still sold. It has a five-year limited warranty that would cover a repair visit to your home if it were still in effect. But the warranty expired about 1 years ago, a sign that its probably time to replace the unit. The current cost is $279 at Lowes and perhaps even less from other retailers if you shop around online.

    If youre reasonably handy, you could probably install a new unit yourself. KitchenAid provides installation instructions that appear straightforward. Lowes could install it for about $120, a local spokesman said.

    You might try repeating the ice trick a couple of times. Disposals sometimes work poorly because of a buildup of grease and other debris. Ice particles whip around in the mechanism and pick up the gunk, helping to clean it.

    Also try another cleaning method that the manufacturer suggests in its care manual: With the unit off, place a stopper over the opening and fill the sink halfway with warm water. Mix one-fourth cup baking soda with water and dump it in. Turn on the disposal as you remove the stopper. If youre lucky, the force of the water, plus the bubbling action and grease-cutting properties of baking soda, will help restore the units performance, as well as eliminate any foul odors. After the sink drains, remove the sink baffle and clean it by hand or in the dishwasher. Replace it before you operate the disposal again.

    New A/C Units Installed At House Of Bread After Burglars Struck Last Month – Hartford Courant - July 11, 2017 by Mr HomeBuilder

    The House of Bread soup kitchen fields a crowd every morning for breakfast, but Tuesday's group had a few new faces. And they came bearing gifts.

    Workers from Marec Heating and Cooling and Neal Sign and Crane Service oversaw the installation of three new air conditioning units at House of Bread. The day shelter on Chestnut Street was full of hot air for nearly a month after burglars destroyed three of the industrial units, causing $30,000 worth of damage for scrap metal.

    News headlines from the theft sparked an impromptu funding drive for House of Bread, which saw thousands in donations from various groups, according to Sister Theresa Fonti, the shelter's co-founder.

    "It's a good feeling, getting so much support from the community," Fonti said Tuesday as a crane slowly lowered the shredded units onto a flatbed truck for disposal. "We're happy to be able to get our air back and continue our ministry."

    The donated money helped close the funding gap for replacing the units about 80 percent of the cost was covered by the shelter's insurance policy.

    And the new cooling system couldn't have come at a better time.

    The two remaining air conditioners were working overtime, according to Matt Beard, the shelter's director. One blew a fuse last week, causing a brief panic in a kitchen that turns out about 200 meals a day for the city's homeless.

    But the worrying is over. Now, Beard is focused on securing the units. He's already installed surveillance cameras on the building's roof and will be placing cages around the units to prevent similar thefts.

    Meanwhile, city police are continuing their investigation into the thieves responsible.

    Best smart thermostats of 2017 – TechHive – TechHive - July 11, 2017 by Mr HomeBuilder

    A smart thermostat will have an outsize impact not only how comfortable you are in your home, but also on your household budget. Heating and cooling your home accounts for nearly half of the average homes utility bills, according to the U.S. Department of Energy.

    A programmable thermostat can help reduce those costs by turning your HVAC system on when you anticipate being home, and off when you dont think youll need indoor climate control. A smart thermostat goes far beyond relying on a simple schedule. It will not only enable you to create more sophisticated schedules for every day of the week, and give you complete control over your HVAC system, even when youre away from home. Weve spent several months testing and evaluating a wide variety of smart thermostats, and now were ready to help you find the right one for your home.

    The Ecobee3s unique use of remote sensors means it can monitor the temperature well beyond the actual thermostat, which makes it an excellent choice. Read TechHive's full review

    Nest usually gets all the attentionand the company deserves credit for shaking up a once sleepy marketplacebut we think the Ecobee3 is the best choice when it comes to smart thermostats. Where the competition relies on measuring a homes temperature in just one spot: Where the thermostat is located, which is almost never in a room that you spend any time in. The Ecobee3 lets you place sensors in multiple rooms in your home, so youll always be comfortable where you do spend most of your time. The Ecobee3 is also compatible with just about every other smart home device you can imagine, including Apples HomeKit ecosystem and Amazons Echo. Could Google Home compatibility be in the works?

    Dont count Nest out of the thermostat game. The Google division has worked harder than anyone to build out a comprehensive smart home ecosystem with its own productsthe Nest Cam security camera series and the Nest Protect smoke and carbon-monoxide detectorsas well as a wide array of third-party products: Everything from ceiling fans to lighting controls and even smart appliances. So why does it garner runner-up status here? Nest counts on your buying other Nest products to help determine when youre home and away, for starters. And anyone investingor planning to investin Apples up-and-coming HomeKit ecosystem should steer clear of Nest products.

    C-wire requirement Most smart thermostats require more electrical power than a set of batteries can provide. Fortunately, they dont require so much power than they need to be plugged into the wall. They rely instead on low-voltage power provided by your HVAC system. Many smart thermostats require the presence of a dedicated C (common) wire for this purpose, while others can siphon electricity from another source, typically the R (power) wire. But the latter practice is known to cause problems with some HVAC systems, including permanent damage. If you pull out your existing thermostat to install a smart model and find no C wire connected to it, look inside the wall to see if theres one that hasnt been connected. If theres no C wire, our advice is to have one installed. Only a couple of the thermostats reviewed here require a C wire, but all the manufacturers highly recommend using one.

    Ease of installation A thermostat shouldnt be difficult to install, even if youre only moderately handy. The manufacturer should provide comprehensive, yet easy-to-understand instructions with plenty of photographs or illustrations to guide you through the process. The thermostat itself should be clearly indicate which wires go where, and most companies provide labels that you can attach to the wires coming out of the wall as you disconnect and remove your old model. The wires themselves should be color coded, but a good practice is to photograph your old thermostat for reference before you take it down.

    Geofencing This feature uses the thermostats app and your smartphones GPS chip to establish a perimeter around your home. When you leave the perimeter, you presumably no longer need to heat and cool your home, or you can at least have the thermostat adjust the temperature so that its not running unnecessarily. When you cross the perimeter again as you come home, your HVAC system can kick into action so your house is comfortable when you walk in the door.

    Remote Access Remote access enables you to control your thermostat from afar, so that you can check in and adjust the temperature from wherever you have a connection to the internet.

    System complexity Each of the thermostats we tested support multi-stage heating, ventilation, and air conditioning (HVAC) systems, as well as heat pump systems. If your home is divided into zones that are heated and cooled independently of each other, youll probably need one thermostat for each zone. A single app should be able to control multiple zones.

    Sensors Geofencing is greatprovided everyone who lives in the home has a smartphone. Motion and proximity sensors offer an alternative means of determining if your home is occupied and therefor in need of climate control. The original Nest thermostat was often criticized for relying too much on its motion sensor. If no one walked past it often enough, it would decide that the house was empty and it would stop heating or cooling. Some smart thermostats can also tap into door and window sensors as well as the motion sensors for your home security system. And proximity sensors on the thermostat itself can trigger a thermostats display to turn on when you walk past it, making the screens a handy feature in their own right, even if for no other reason than providing a nighttime pathway light.

    Smart-home system integration Every smart thermostat comes with an app so you can control it with your smartphone or tablet, but the best models can also be integrated with other smart-home devices and broader smart-home systems. This can range from being able to adjust the temperature with a voice command via an Amazon Echo or Google Home digital assistant to linking to you smoke detector so that your fan automatically turns off when fire is detected, preventing smoke from being circulated throughout your home. Other options to consider include IFTTT and Stringify support, Apple HomeKit compatibility, smart-vent connectivity, and tie-ins with home security systems.

    User interface Long gone are the days when a thermostats user interface consisted of numbers on a dial. The more sophisticated a device becomes, the more difficult it can be to learn to use. The last thing you want to be doing is staring at inscrutable hieroglyphics on the wall when all you really want is to be warmer or cooler. A smart thermostat should convey important information at a glance and should easily adapt to your specific needs.

    We installed these thermostats in a single-family home with a conventional HVAC system and used each one for a week or more to determine how effective it was at maintaining a comfortable environment. The homes existing thermostat was wired with G, R, W, and Y wires. There was also a C wire in the wall that was connected to the furnace, but that had not been previously used.

    While there is no regulated standard for color-coding HVAC wires, industry practice has the G wire connecting the thermostat to the fan. This wire is typically green. The R wire, typically red, is for power. Some systems have separate power wires for heating and cooling and are labeled RH and RC respectively. The typically white W wire is for auxiliary heat; i.e., a second source of heat. The Y wire, which is typically yellow, connects the thermostat to your air conditioner. Finally, the C or common wire is used to carry power and is typically blue (think cerulean if you need a mnemonic).

    Alphabet’s Dandelion Wants to Water Cool/Heat Your Home – PCMag - July 11, 2017 by Mr HomeBuilder

    Replace your heating and AC energy bills with a $20,000 geothermal system buried in your yard.

    Part of the Alphabet (formerly Google) empire is the moonshot factory simply called X. X focuses on inventing and launching "moonshot" technologies to make the world a better place. The latest of those technologies just became an independent company called Dandelion.

    Dandelion was an internal project at X for several years with a focus on using geothermal energy to cut down on carbon emissions in the home. This isn't a new idea, but it is an expensive one, which Dandelion aimed to solve. And solve it they have if Kathy Hannun, CEO of Dandelion is to be believed.

    Rather than using fuel oil, propane, and lots of electricity to heat and cool your home during the different seasons, it's possible to do the same thing using geothermal systems. For home owners, that means taking advantage of the ground under their yard.

    That ground stays at about 50 degrees Fahrenheit all year round. A geothermal system for heating/cooling works by drilling and installing U-shaped plastic pipes and running water through them. In the winter the water takes up the heat in the ground and a geothermal heat pump turns that into warm air pumped into your home. In the summer, the system works in reverse and pumps the warm air out of your home to cool it and deposits the extracted heat in the ground.

    The expensive part of such a system is the installation and in particular the drilling, which is what Dandelion focused on solving. What they created was a brand new drill capable of drilling very deep holes with very little waste and completing the required ground loop piping in less than a day. Existing systems requires large machines, create a lot of mess, and take up to four days to complete the work.

    According to CNN, existing geothermal system installations cost $60,000 to install. Dandelion cut that price down to just $20,000, which is still a lot of money until you factor in the energy cost savings each year.

    Dandelion is now open for business and will initially be offering its system in New York. It wants to partner with local heating and cooling installers to help roll out the service and there will be a financing program through Collaborative Fund in the near future to help with the cost.

    Alphabet lab turns out new geothermal company for residential heating and cooling – Utility Dive - July 11, 2017 by Mr HomeBuilder

    Dive Brief: Dive Insight:

    Heating and cooling buildings accounts for almost 40% of carbon emissions in the United States, and so Alphabet's engineers have spent years developing ways to make geothermal systems more affordable and less intrusive to install.

    Dandelion CEO Kathy Hannun said the project was started "because we realized millions of homeowners are using expensive, truck-delivered fuels because they dont have access to better options today." But the key to signing on customers, particularly residential, would be in reducing cost and time to install.

    Along with Hannun, Dandelion will be run by James Quazi, who will lead the company's technology development.

    Over at the Google X blog, Hannun gives some background on developing the new geothermal installation process, including modifying drills and and considering liquid nitrogen to install a system of underground pipes.

    "After months of testing, we hit upon a design for a fast, slender drill that hit our objectives," the new CEO writes. "It could drill just one or two deep holes just a few inches wide, and compared to typical installation rigs, it produced less waste and took up much less space as it operated."

    While installing the tubes typically takes up to four days, the new process could be done in one day and "left a typical suburban backyard relatively undisturbed."

    Dandelion is now operating in the New York Hudson Valley and Capital Region, and the company says its systems can provide renewable heating, cooling, and hot water and include monitoring and a smart thermostat.

    Shading and lighting retrofits slash energy use in New York ‘Living Lab’ office demonstration – Phys.Org - July 11, 2017 by Mr HomeBuilder

    July 11, 2017 by Julie Chao Thermal imaging was used to measure surface temperatures near the window, which in turn was used to evaluate the occupants level of thermal comfort. Credit: Berkeley Lab

    By using advanced lighting and automated shades, scientists from the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) found that occupants on one floor of a high-rise office building in New York City were able to reduce lighting energy usage by nearly 80 percent in some areas.

    The dramatic results emerged at a "living laboratory" set up to test four sets of technologies on one 40,000 square-foot floor of a building.

    Berkeley Lab partnered with the Building Energy Exchange (BEEx), an independent nonprofit, to demonstrate that even in relatively modern office buildings, installing the latest generation of smart, actively controlled energy efficient lighting and shading can dramatically lower energy costs and enhance the quality of the work environment. These results will be important in speeding market adoption of emerging energy-saving technologies, according to Berkeley Lab scientist Eleanor Lee, who led the project.

    "Context matters when it comes to figuring out where the market barriers are with respect to contractors, facility managers, and office workers isolated tests in a laboratory environment are often not enough," she said. "Reducing stakeholders' uncertainty about performance and occupant response in a real-world setting can be critical to accelerating market adoption."

    On the living lab floor, T5 fluorescent lights were swapped out for dimmable LEDs with new sensors, which were adjusted throughout the day using advanced controls depending on daylight levels and occupancy of the space. Automated shades were raised or lowered to open up views to the outside, admit daylight, or reduce glare as needed. Researchers monitored the effects of the retrofit for six months, following a year-long baseline monitoring period before the upgrades were installed.

    Compared to the baseline condition, energy use for lighting in the 40-foot deep perimeter zone on the living lab floor declined 79 percent, while the associated peak lighting electric demand went down 74 percent. Much of the savings came from the switch from fluorescent lamps to LEDs and being able to dim lights across the floor, not just next to the windows. The advanced controls enabled more granular fixture-by-fixture control with wireless sensors and communications, enabling zone control to be customized at the work-group level.

    Many of the decisions related to configuring the controls were driven by the desire to maintain bright interiors and access to outdoor views. Despite the huge reduction in energy use, people surveyed on the living lab floor were generally content with the lighting levels and indoor temperatures.

    Though heating and cooling use weren't monitored during the study, researchers estimated that a building-wide retrofit would have provided total electricity cost savings of $730,000 a year, assuming an average rate of $0.20 per kilowatt hour. Using industry estimates of typical installed system costs ranging from $3 to $10 per square foot, the retrofits would pay for themselves in three to 12 years. The researchers also emphasized the importance of installer and operator training, along with systems that have strong diagnostics and troubleshooting tools, in boosting the adoption of these technologies.

    BEEx acted as local managers for the Living Lab and documented lessons learned across the entire process of technology selection, procurement, and installation. These lessons have formed the backbone of multiple educational resources, from exhibits to professional training sessions and toolkits, aimed at professionals who make decisions about lighting systems in commercial spaces.

    "Using everything we learned on this project, we've developed a series of tools that will really help the engaged design professional or building owner make better decisions about lighting system upgrades, and avoid the common pitfalls on the road to a high performance office space," said Yetsuh Frank, BEEx managing director of strategy and programs."

    The market for efficient lighting and shading controls continues to evolve. When the study began in late 2013, the researchers said, even basic features like wire color weren't yet standardized among technologies, causing confusion during installation.

    But "manufacturers have really thought about how to reduce the complexity of their systems" over the past decade, Lee said, making them easier to install and more turnkey, while costs continue to come down. She added: "In the next 10 years, as components integrate with coordinated, optimized systems, we anticipate these technologies will deliver even better performance at even lower costs."

    Alphabet’s Dandelion Offers Geothermal Heating & Cooling – Android Headlines - July 11, 2017 by Mr HomeBuilder

    Geothermal energy is one of the lesser-known types of renewable energy, but a new Alphabet company called Dandelion wants to change that by harnessing the heat underneath your yard to heat and cool your home. For the time being, the service is only available in certain areas of upstate New York. The signup website allows you to check if your home is within the serviceable area by zip code, and boasts immediate savings over your current energy payments thanks to zero down financing for qualified customers. Since the system simply either draws heat into your home from the earth below, or wicks heat from your home down into the earth, there are no service charges to pay, so youre only paying for your installation over time. The payments are touted as being fairly low. Your installation also comes with a smart thermostat.

    If your home is within the service area, the process of signing up starts with a chat aboutyour home to assess it for installation with Dandelions experts. If that checks out, theyll come out to your house and plan the installation. If all goes well, the installation itself should take 2 or 3 days, and is done by contracted professionals. The installation can be done alongside a traditional heating and cooling system based on gas or electricity. Nodes are installed under the floor and in the walls of your home, and are hooked up to pipes that go down into the ground. From there, the system is able to pull heat up from the ground, or push it down into the ground from your home. Thanks to the simple setup, a Dandelion hookup can not only heat and cool your home, but can even be used in place of an electric or gas-powered water heater.

    The newest spinoff from Alphabet to become an independent company was born within X, and in its current form, consists of X product manager Kathy Hannun serving as CEO, X technical program manager James Quazi as CTO, and former Conergy exec Katie Ullman in charge of marketing. The operation brings together experience from both inside and outside Alphabets wheelhouse, includingSolarCity and Mosaic. The company is still in its infancy, and there is so far no word on when or if the program may expand.
