During the winter, the supply air from an HRV will be somewhat dryer than the supply air from an ERV, so choose an ERV if you're worried. But I don't think an HRV will cause any problems at all in your climate.If you use EPS, a more environmentally responsible option, it starts out at about R-4/in and maintains R-4/in. Either way, 2.5" is enough to get R-20. R-20 foundation walls are insulated in different ways so the answer would depend on your assembly. R-40 above-grade walls are done in different ways so the answer …That’s what Rus Pearson would like to know. “Some say spray the roof deck, allowing the attic air to become conditioned, which is great for the [heating and cooling] ducts in the attic,” Pearson writes in a Q&A post at Green Building Advisor. “Others say spray the attic side or the ceiling to allow the attic to vent.A radiant floor system powered by a boiler that produces 75,000 or 80,000 Btu per hour is overkill, what Theodore Bernstein would call an “atomic flyswatter.”. The case for an expensive heating system built around a powerful boiler begins to collapse as the building enclosure becomes better insulated and air-sealed.Green is often less expensive when all things are considered Sustainable building often seems more expensive than conventional building. Many of the building materials that make houses more durable and easier to heat and cool aren’t cheap. Complicated systems that allow a certain amount of energy …R: Anything to reduce vibrations transfer would be ideal based on what i understood from the calls I made. Q: it seems that to use the boost function, wiring is just armored conduit to a wall box, and then romex to the switch, which I assume is just a standard 120 v. 15-20 amp wall switch.Tankless water heaters have one advantage over conventional storage units: no standby losses. Instead of keeping water hot around the clock, regardless of whether it's actually needed, tankless units heat water only when a tap or an appliance is turned on. By rights, this should mean lower energy consumption, a decidedly green advantage.Looks like MBtek is getting a new pump soon. Appears to be an R290 pump (propane). Global warming coefficient is just 3 on propane, so that's a bit improvement. They also claim it has an output of 175*F. I'm a little skeptical of that. But I have seen other R290 heat pump manufacturers claim similar numbers.Mar 25, 2016 · Maybe you are building a new home with an unconditioned vented attic. The house is framed, sheathed, and roofed. The drywall contractors have finished their work, so now you’re ready to insulate the attic floor. If you are an owner-builder, this may be the first time you’ve done this. So what do you need to know? The lifecycle “cost” of carbon involved in building construction can be measured by the global warming potential (GWP) associated with the manufacturing and use of each building component. This is measured in carbon dioxide equivalence (CO2e). My focus was specifically on insulation, which is a product that customers and contractors ...The top edge of the insulation between the exterior wall and the edge of the interior slab shall be permitted to be cut at a 45-degree (0.79 rad) angle away from the exterior wall. Slab-edge insulation is not required in jurisdictions designated by the building official as having a very heavy termite infestation.The ratio rule tells you what percentage of the total R-value of insulation you need to put above the roof deck. The ratio rule applies to hybrid roof insulation with rigid insulation above the roof deck and air-permeable insulation below. Although the model code (2018 IRC) doesn’t call it out, you should use the rule for air …Potential for pyrolysis. Pyrolysis is defined as the chemical decomposition of wood or coal by the application of heat alone in the absence of oxygen. In short, it is the repeated heating of wood resulting in its changed chemistry and ignition temperature. Typically, this process happens over a long period of time and includes many cycles of ...During the design phase we read articles from Green Building Advisor and the Journal of Light Construction about energy-efficient building practices. We followed the local building code and hired an excellent general contractor. The topic of wintertime humidity never came up in relation to building …Interior partition walls create one of the trickiest transition points when installing an interior air barrier. As seen here, the wall breaks the continuity of the air control layer at the ceiling. This needs to reconciled and sealed. I’m from Minnesota, one of the few areas in the lower 48 that still regularly uses polyethylene sheeting as a ...This means that radiant heat can provide comfort at a lower air temperature than is required with forced-warm-air or baseboard hot water heat. You might be able to keep your thermostat lower — say 65 degrees—and be perfectly comfortable with radiant-floor heating, while 68 or even 70 degrees would be required with other systems.If you want to improve the energy performance of an older house, one of the first steps is to plug your attic air leaks. Although many GBA articles address aspects of attic air sealing, no single article provides an overview of the topic. This article is an attempt to provide that missing overview. I’ll try to explain how you …When it comes to constructing and fitting out buildings, our focus is—or at least should be—on the holistic impacts of each decision we make. The best stewards …Corbett Lunsford just released a video on his Youtube channel called "The Science of Sick Building Syndrome and Environmental Sensitivity" and in it they discussed the fact that when Pex is tested in a lab the scientists were told that the tubing had to be regularly flushed out with fresh water for 14 days in order for …Mar 25, 2016 · Maybe you are building a new home with an unconditioned vented attic.

The house was built conventionally, with 2x4 walls, fiberglass batt insulation, fiberboard sheathing, and hardboard siding. He plans to tear off both siding and sheathing and remove the …Primorsko-Akhtarsk Air Base Airport (AG2988) located in Primorsko-Akhtarsk, Krasnodar Krai, Russia. Airport information including flight arrivals, flight …Vented attics are the least expensive way to insulate the top of the house. 2. All exterior insulation on the roof or some on top with fibrous insulation beneath. Second on Kohta’s list is putting all or some of the insulation on top of the roof. This keeps the roof sheathing protected from moisture damage because it stays warm.R: Anything to reduce vibrations transfer would be ideal based on what i understood from the calls I made.

Make it easy for occupants to use, including returning it to the sealed position. Attics can be as cold as the outdoor air in winter and much hotter than outdoor air in summer.2. vinyl siding comes down to about 8-12” from the top of finished grade. 3. the sill looks to be in decent shape but it not airtight on the foundation. 4. the exterior foundation face is a mix of rubble stone, faced with some stucco. Lots of stucco has broken and crumbling, as is some of the rubble. 5.If you use EPS, a more environmentally responsible option, it starts out at about R-4/in and maintains R-4/in.

During the summer, this type of heat pump transfers heat from indoor air to the soil around your house. In some cases, it may transfer heat from indoor air to the water in a drilled will, or to a nearby lake or pond. During the winter, a GSHP collects heat …Carter Scott was one of the first builders bold enough to build a cold-climate home heated by only two ductless minisplit units (one in the downstairs living room, and one in the upstairs hallway). Skeptics predicted that the unheated bedrooms would be cold and uncomfortable. Yet Scott was confident that the home’s excellent thermal envelope — …GreenBuildingAdvisor.com. 14,464 likes · 2,933 talking about this.
