Better yet, meet the code requirement for R-value entirely with the foam layer, and skip the fluffy insulation. Green builders don't use XPS -- instead, choose EPS or polyiso.It “sort of works,” said Green Building Advisor Michael Chandler, but a better option is installing foil-faced duct insulation (not foil-faced bubble wrap) after ducts have been sealed with mastic and checked for air-tightness, preferably by an independent tester. Foil-faced bubble wrap “is not Energy Star or Manual D approved,” he ...The specific heat capacity of building materials varies. In general, denser building materials have a higher specific heat capacity per unit of volume than less dense materials, which is why concrete, stone, and gypsum wallboard are more likely to be used to provide extra thermal mass than wood. Three analogies: cistern, frying pan, truckThe official recommendation from the ADC is that flex ducts should sag no more than 1/2 inch per foot of length between supports. The supports need to be at the manufacturer’s recommended spacing, but no longer than 4 feet. The straps that hold up the flex duct need to be no less than 1.5 inch wide.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.

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.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.Mar 25, 2016 · Maybe you are building a new home with an unconditioned vented attic.

Geothermal heat pumps have a reputation for being efficient and “green”; is it deserved? In contrast, feedback from owner experience, and substantiated by discussion on industry boards and forums, paints a less flattering picture of the realities of geothermal.Air conditioning can also create condensing surfaces. The same phenomenon can happen in reverse in the summertime. Let’s say the outdoor air is 85°F and the relative humidity is 75%.

A typical kneewall is between 3 and 5 feet high.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 — …All heat pumps work on the same principle, moving heat from one location to another with the help of a closed refrigerant loop, a compressor, and a heat exchanger. In winter, heat is extracted from air, water, or the earth; this heat is used to heat the house. In summer, the process can be reversed so the heat pump pulls heat from the inside and …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 independence–photovoltaic …Originally developed by Skanska and C Change Labs, EC3 was incubated by the Carbon Leadership Forum and nearly 50 industry partners until its public launch at Greenbuild 2019, at which time the nonprofit Building Transparency was founded to house EC3. Its mission is to provide open-access data on …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.UGREEN is a company that provides green building advisory services to help organizations design, build, and operate sustainable projects.

If you are an owner-builder, this may be the first time you’ve done this. So what do you need to know? Most of the world, especially the green building community, assumes that “European” implies “more energy-efficient.”. When it comes to windows, this automatic presumption of superior energy efficiency is both so common and so misplaced that it deserves a name: the Presumptive European Superiority Syndrome. Guest Blogs.Navigating the decision-making process to ensure the best performance of a home can be challenging. We need to balance allocation of resources between 1. load reduction—which primarily involves upgrading the thermal enclosure—2. conversion from fossil fuel–powered to electrically powered systems, and 3. implementation of renewable …Most of the world, especially the green building community, assumes that “European” implies “more energy-efficient.”. When it comes to windows, this automatic presumption of superior energy efficiency is both so common and so misplaced that it deserves a name: the Presumptive European Superiority Syndrome. Guest Blogs.It’s easy: Keep your heat from going through the roof. Saving money on heating-fuel costs is a lot simpler than negotiating with OPEC or your local utility.

One is the short building season. The other, of course, is Alaska’s Arctic cold. But for general contractor Thorsten Chlupp, whose firm, Reina LLC, is based in …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.Directly under the snow, the top few inches of soil might be 15°F. Two feet lower, the soil temperature might be 32°F. At 5 feet below grade, the soil temperature might be 40°F. Under the basement slab, the soil temperature might be 50°F or 55°F. Now let's look at the foundation wall.Installing Rigid Foam Above Roof Sheathing - GreenBuildingAdvisor. Musings of an Energy Nerd. By Martin Holladay | July 8, 2022. This approach can be used to create an unvented conditioned attic, allowing attic ducts to be installed inside a home’s thermal envelope.

BS* + Beer.The should match the 99% and 1% design temperatures from ASHRAE, which are also given in Table 1A in Manual J from ACCA. If the 1% summer design temperature is 91°F, as in Atlanta, a Manual J report showing that the load calculation was done with 97°F will result in an oversized air conditioner. Actually, even if the load …Dec 27, 2023 · According to principal Matthew Fine, the feasibility of building six identical high-performance homes on a single parcel was never in question. What was in question, however, was achieving such a feat “at an affordable level.”. The homes themselves are “fairly modest” and “contextually appropriate,” Fine says. One builder posted that when he ended up installing siding he shimmed the map siding at these locations to have a flat wall. @Dennis_vab Zip-R 12 is about $4.30 sq/ft without crazy amounts of sheathing. Im currently working on building a house and will be using Zip-r12 in zone 6a. Nailboard panels for roof as well.Vapor Control for Continuous Insulation – Zone 6. Looking to install continuous insulation with no cavity insulation on a tiny residential home in Zone 6.

Join the community of …When you switch from an air conditioner to a heat pump and keep your furnace, you now have two heating systems. You still have the furnace, but the heat pump will probably do most of your heating. Above a certain temperature, the heat pump does all the heating. Below that temperature, the heat pump turns off and the furnace takes over.BEAM’s combined functionalities allow users to make project-specific materials selections, identify materials with the biggest carbon penalty, and find alternatives. Users input the main dimensions of a building and are given a list of available materials for the primary assemblies and the carbon impact of each product.However, these vacuum insulation panels (sometimes called VIPs) could make a great deal of sense in certain value-added products like refrigerators, freezers, water heaters, and entry doors.

This is measured in carbon dioxide equivalence (CO2e). My focus was specifically on insulation, which is a product that customers and contractors ...This $250,000 figure was based on 80% of our bank’s expected appraised value of our design at $312,500.
