first_imgDoes it pay to turn down the heat at night when you have a radiant-floor heating system? David Meiland and a heating contractor are having trouble seeing eye to eye on that question.Meiland says the house they’re discussing is a slab-on-grade with R-10 insulation below and PEX tubing cast into the slab. In another part of the house, the floor is framed, with PEX installed below in tandem with aluminum plates that help distribute the heat. The boiler is a 30-kW electric model with an outdoor reset.In a Q&A post at GreenBuildingAdvisor, Meiland writes, “The heating contractor advised the homeowner that setting the night-time thermostat temperature too low would cause the system to work very hard in the morning to get the slab back up to temperature, and therefore waste energy.“My opinion is that lowering the setpoint at night is a good thing, as the system will put fewer BTUs into the house, saving energy. When the system ramps up in the morning, it will reheat the slab without any loss of efficiency. Fewer total BTUs will be put into the house.” High-mass floors respond slowlyWhile there is a mix of flooring types in the house, several readers pointed out that the high mass of a concrete slab will not change temperatures very quickly — and that has a bearing on the practicality of turning down the heat at night.Cramer Silkworth, for example, writes that if the house is well insulated, its occupants may not experience an overnight drop in temperature even with the thermostat turned down. “The slab’s mass combined with a well-insulated envelope may carry it through the night with only a small drop in temperature,” he says.When morning rolls around, he adds, it will take some time before the slab can be brought back to temperature. “The system won’t ‘work hard’ to bring the slab back up to temperature (it may be at full load, but the heat’s not being lost any faster than it normally would),” Silkworth says, “but it will take some time, such that you’d need to set the system to come on a couple hours before you want the morning temperature reached.”The relatively slow response to change also can lead to uncomfortable temperatures both in the morning and later in the day, Keith Gustafson says.“If the setback is too deep and the concrete loses significant temperature, it will take hours to reheat, and the residents may be uncomfortable,” Gustafson writes. “Radiant just does not recover like baseboard or hot air.”“In the morning,” he adds, “your thermostat turns back on but the physics of thermal mass say you need to put ‘x’ BTUs into the slab before it will rise in temp, and thus allow the room to rise. If you put enough BTUs into it quickly enough to ramp room temperature up, then the mass will cause it to overshoot — and how does having the room at 78 degrees 3 hours after you go to work save energy?”Dan Kolbert makes the same point. Not only does it take a long time for the temperature to come back, but it puts a strain on the heating system. “One client went away on vacation, turned the heat down to 50,” Kolbert writes. “It took almost a week to get back to temperature, and she had very little hot water while she waited.” RELATED ARTICLES All About Radiant Floors Radiant-Floor Heating Goodbye Radiant Floor Is Radiant Floor Heat Really the Best Option? Heating a Tight, Well-Insulated House Radiant-Floor Heating: When It Does—and Doesn’t—Make Sense The heating system may be overkillGBA senior editor Martin Holladay adds another wrinkle to the conversation: in a tight, well-insulated house, you don’t need much of a heating system when the design temperature is a relatively balmy 30 degrees, as is the case with Worthington’s house.“What you need is a good airtight envelope with high levels of insulation and excellent windows,” Holladay says. “If you have those features, you won’t need much heat at 30°F — certainly not a high-mass radiant floor with a condensing gas water heater. Your internal loads — the refrigerator, lights, and TV — will provide much of your home’s heat. A few ductless minisplit units are all you will need for cool nights.” Would better thermostats help?Writing from the San Francisco Bay area, Monty Worthington describes the trouble he’s had in regulating temperatures in his new house with radiant-floor heating and very basic thermostats. After some tinkering, he’s learned that a 3-degree setback overnight and in the middle of the day seems to work. But he has to program the heat to kick on at 5 a.m. in the bedroom in order to be comfortable two hours later when he gets up.Meiland says he had the same experience while living in that area in a house with a staple-up radiant floor system. “When the temperature swings were in the 30-degree range, it was necessary to start gaining or losing heat 3 to 4 hours in advance,” Meiland says. “This was a quick-responding system: 7/8-in. fir plank subfloor, 5/16-in. hardwood over, well-insulated underneath.”AJ Builder suggests that a forced-air heating system has faster response times than radiant-floor heat, but Worthington wonders whether a more sophisticated thermostat would help.Silkworth had earlier suggested that some thermostats are capable or learning how long it takes the heating system to reach the set point and automatically compensating for it.Kevin Dickson writes, “The newer Honeywell thermostats can ‘learn’ the temperature response of your house and compensate to prevent overshoot in any house.” Meiland thinks the heating contractor has it wrong, confusing a period of high demand in the morning with low efficiency.That’s the focus of this month’s Q&A Spotlight. Our expert’s opinionHere’s how GBA technical director Peter Yost sees it:First, a bit of a rant on radiant floor heating. While there is no denying the thermal comfort of a radiant floor heating system, the following claims are often made but are just not true:Radiant floor heating is more efficient than other heat distribution systems.Radiant floor heats objects and surfaces, not the air (this is often cited to support #1 above).Even at peak delivery, radiant floor heating systems deliver a maximum 60% of their heat by way of radiation. The two factors driving radiant heat transfer are surface area and surface temperature differences. At floor temperatures in the low 90s (F), net radiant transfer, particularly with people (our surface temperatures are in the low to mid 90s), is minimal. And the thermal comfort of the warm floor is more one of [no-glossary]conduction[/no-glossary] to your feet than radiation.And as a slow-acting, high thermal mass system, any initial air temperature from setback is steadily eroded until at equilibrium, the air temperature profile of a radiant floor heating system is pretty much the same as any heating distribution system and more dependent on the performance of the building envelope.Just because someone decided to name this system “radiant floor heat” does not mean that the laws of thermodynamics and rules of heat transfer are suspended by terminology.It’s not that radiant floor heating cannot work well; it’s just that it is a very expensive way to provide space conditioning — and one that only provides heating, not cooling, at that.With any high-mass heat distribution system, setback can be a real balancing act between thermal comfort and energy efficiency. Sure, setback saves BTUs, but if the main advantage of radiant-floor heating is thermal comfort, the prolonged thermal lag of a high mass heating system in the morning or when you return home in the evening is not likely to be very welcomed.And depending on solar gain, particularly in the morning, overshoot can be a big problem with nighttime setback of high-mass heat distribution systems. Certainly, setbacks cannot be as deep as with faster-acting heat distribution systems.We have ramp-up, multi-input setback thermostats for heat pumps, ones that use outdoor temperature readings and patterns to minimize strip heat use. I don’t know if similar thermostats are available for radiant-floor heat, or if the heat pump thermostats can be used with radiant-floor heat, but they are not inexpensive and can be “fooled” by dramatic weather changes.The long and the short of it: Specify or use radiant-floor heating for its steady delivery of thermal comfort, not because it is more efficient or well-suited to energy savings associated with setbacks.last_img read more

first_imgKnee, ankle, elbow pads, and bracesJoint pads and braces are invaluable in many situations, both palliative and preventative. Bring some for yourself, and keep an eye out for any member of the crew that could use them. Power banks and rechargeable batteriesHaving backup power options is a must on set. I recommend multiple high-capacity battery banks (10,000 mAh or greater) as well as a set of rechargeable AAs and AAAs. Folding table and chairsHaving your own will keep you from monopolizing others’. This is especially important if you have a role that will require you to be relatively stationary.Image via Mike_shots.Permanent markersBring an assortment of colors and weights to mark your equipment, water bottles, and so on. Pocket knifeone of the most essential tools for any member of the crew, pocket knives come in handy nearly every day. Safety GearSets are tricky. People can get hurt, and things can go wrong at any moment. Having a basic safety kit will help you manage these uncontrollable factors. Here are some essentials:Image via Arshad.Atar.Extreme weather protectionDisposable rain ponchos, heavy coats or waterproof jackets, space blankets, and heating or chilling pads are all a great place to start. Water is essential no matter where you are shooting — have a reliable, insulated water bottle. Know the extreme weather possibilities of the region you’re shooting in and be prepared.Image via PRESSLAB.First aid kitIt is my opinion that every member of the crew should always show up with a first aid kit. Even with a set medic, always knowing where a first aid kit is saves critical time when someone gets injured. Rope and stringIf you can, pack a good length of medium-weight rope and a spool of heavy-duty thread in your kit.Image via ponsulak.Clips and clampsA-Clamps, clothespins (C47s), and C-Clamps (among other forms of clamps) are always in short supply on set. Bring some for yourself and extra to share. Multi-toolA multi-tool, such as a Leatherman, can be a replacement for your entire tool bag in a pinch. While not as good as other dedicated tools, multi-tools offer sufficient performance in a convenient package. When deciding on the elements of your kit, consider everything you know about the production as well as the role you will be performing.Are you going to be working in the audio department? Make sure to bring a good selection of cables, adapters, and headphones with you. Camera department? A lens-cleaning kit, microfiber cloth, and card/media holders will all be welcome additions to your kit. Wardrobe? Bring a steamer, clothes hangers, and a foldable clothes rack.Each department has its own needs, and each role within each department its own more-specific ones. Think through what you will be doing in your role, examine this list for some ideas, and get packing!Cover image via ponsulak.Looking for more information on film and video production?

Cable tiesWhether fabric or plastic, cable ties have many uses on set.Image via Alex Brylov.RadiosRadio communication is the backbone of competent film production. Bring a set or two of walkie talkies with you. Security earpieces are a huge upgrade (many productions actually require them) that you can purchase for about $10-$30.

The rules are the same as when you were a kid: keep it away from eyes.Image via Garsya.TapeGaffer’s tape is best, but bring whatever you have. Electrical and masking tape find common uses on set, as do the humble Duct and scotch tapes. Tape measureTape measures have dozens of practical uses every day on set. Have one for yourself and one to lend out. Comfortable boots or shoesWhile not technically tools, a bad pair of shoes will ruin your day and increase fatigue each day on set. I usually wear my hiking boots on days when I will be standing and walking a lot. A good pair of supportive running shoes is also great. As with any labor job, no open-toed shoes. You know the lingo, you landed a gig, and you’re ready to work. So what do you need to bring with you for your first of film or video production?In a recent article, we talked about some of the basic things to know about film and video production before your first day on set. In this article, we’re going take a look at some of the basic components of a good multi-purpose kit.In film and video production, the “kit” is the set of tools, gadgets, and other necessities each member of the crew brings with them to execute their particular job. Every member of the crew has their own particular set of tools. No two kits are the same, and they will vary from production to production.Here is a list to get you started thinking about the basics of a good general-use kit of your own.ToolsImage via olmarmar.A basic set of tools will come in handy every day on set. Some of the most useful include the following:ScrewdriversBring small, medium, and large phillips and flat-heads with you. WrenchesAdjustable wrenches like crescent wrenches offer a high degree of flexibility without taking up a ton of space in your bag. Useful Additions to Your KitBeyond tools, here are some more considerations for your kit.Image via Burakova.Notebooks and pensBring a full-size notebook, one or two pocket-sized notebooks, and a nice selection of pens and pencils. Take notes, always. Allen wrench (hex key) setBring a folding, multi-key set. Flashlights, headlamps, USB lightsSets are usually dark. Have a small, high-output flashlight on your keychain for easy access. Headlamps are a direct upgrade to flashlights. USB lights are cheap, relatively low-output, and incredibly useful in about 5-dozen situations. Bring what you can and a couple extra to lend out. Leather or other insulated work glovesHeavy duty work gloves are essential if there is any possibility that you will be handling electricity or lighting equipment. Bring a pair just in case.Image via In Green.Tool beltYou’ll notice that most of the seasoned crew carry their most-used tools on a tool belt. Tool belts cut down on how much you need to carry around with you, while also reducing the running back-and-forth to fetch tools.last_img read more

first_imgHere’s a true story: One non-hustler says to another non-hustler, “How’s it going?” The second non-hustler says, “I am on the right side of the dirt.” The first non-hustler says, “Well, that’s as good as it gets.”No. That is not “as good as it gets.” “It” gets way better than just being on “the other side of the dirt.”What You Tell YourselfNon-hustler’s make very poor language choices. Those choices provide a clear view into their mindset, and the language they use puts them in a disempowered state. Words like, “I am on the right side of the dirt,” or “Any day above ground is a good day.” That’s not setting the bar very high, is it?If you ask a non-hustler how they are, they’ll say, “I’m okay.” Why on Earth would you want to be “Okay.” They’ll tell you that they “hate Mondays,” “can’t wait for Fridays,” that Wednesday is “hump day,” and that you shouldn’t “work too hard.” Who wants to be “okay?” That sounds like mediocrity, doesn’t it?They’ll also tell you they are “living the dream,” but said in such a way to make sure you know that they aren’t deeply engaged with what they’re doing and that they are cynical. This is how non-hustlers identify each other.Empowering Words, Empowered MindsetHustlers are different. If you ask them how they are, they will say something like,“Excellent,” or “Wonderful.” They tell you that they are “killing it,” or that they are “crushing it.” This is a very different mindset than that of the non-hustler, and so it comes with very different language choices.The hustler doesn’t notice anything different about Mondays and Fridays. On both days, they’re engaged with their work and their life. Because they are engaged in their lives, they don’t see Wednesday as being significant because it is half way to the weekend; they like all the days.You’ll never hear a hustler say, “Don’t work too hard,” or that they are “just happy to be on the right side of the dirt.”Your brain is designed to keep you alive. That is its primary function. But that doesn’t mean that your goal should be simply survival. You are capable of way more.You are here to do something meaningful, to passionately engage with life, and to thrive.last_img read more
