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.The plan is to waterproof the exterior, install drain board, a perforated drain along the base of the foundation and an inground gutter system. However, we are stuck on the water proofing step. Pressure washing the exterior concrete removed all loose coating, but most of the fiber and black coating remain firmly in place.A. In Climate Zone 6, I would advise the use of at least 2 inches of rigid foam before switching to fluffy insulation. 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.The Science Based Targets initiative (SBTi) recently unveiled a draft for pilot testing of its new target-setting guidance for the building sector, set to go into effect in the first half of 2024. SBTi is a partnership between the Carbon Disclosure Project (CDP), the UN Global Compact, World Resources Institutes (WRI), and World Wide Fund for ...If you do it this way, you should have very little vibration or sound coupling into the structure from the outdoor units. If the stand itself is vibrating, add some mass. An easy way to do this is to attach some solid concrete 1/2 blocks (about $1 each) to the underside of the shelves where the units are.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.

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 Fairbanks, yet another motivator … Green building is about process first, products second. But the process of building involves myriad products and materials. Green choices offer ways to improve indoor air quality, water and energy efficiency, durability, and comfort. Paints and finishes on floors, walls, cabinets, and ceilings should be low in VOCs. Installing the water heater. Installation of a heat-pump water heater is basic plumbing, electrical, and HVAC all in one. The first step is to run the water lines. Way back when I ran the PEX for the water supply lines in the house, I had run a line from the main supply, formed it into a loop in the utility room, and then into a …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 big difference in temperature between the room air and the heated air also creates variation in temperature from one part of the room to another. A heat pump blows lower temperature air into the house, and that’s better for comfort. A heat pump, by contrast, adds a greater volume of lower temperature air.Registers are square or rectangular fittings with movable dampers to adjust airflow volume. Lightweight stamped-steel registers are used for wall and ceiling applications; heavier-duty cast or welded registers are used in floors. Diffusers cover supply openings in ceilings. They have angled vanes that discharge air in a spreading pattern.In my recent post, Living the 100-amp Lifestyle, I quoted the Australian philosopher Samuel Alexander as saying, “Efficiency without sufficiency is lost.”. For years, we have been talking about building our homes with greater energy efficiency; in the meantime, on average, they have doubled in size, eating up all those energy savings.Nov 20, 2023 · The SANCO2 split-system heat pump water heater offers benefits that include energy efficiency, low-GWP refrigerants, and the possibility in some situations to provide space heating. Over the last couple of years, there’s been a lot of buzz about the SANCO2, a newer type of air-source heat-pump water heater (HPWH) from ECO2 Systems. A High-Performance Building Envelope for a Net-Zero Energy House. Working out trouble spots during the design phase helps keep a demonstration house on time and on budget. Green Homes.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.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 …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.

With most of these furnaces, the low-fire output is still 60% or more of the high-fire output. When a furnace with a low-fire rating of 60% is oversized by a factor of 1.7, you could cover 99% of the building’s heating needs at low fire.The code recommendations for 2×6 walls assume (in Climate Zone 6) that any exterior rigid foam has a minimum R-value of R-11.25 — your polyiso will perform at R-9 or R-10 in cold weather, so it’s not quite thick enough — and fluffy insulation between the studs rated at R-19 or R-20.Green Building Advisor Customer Service.

A single-stage system is oversized for most of the year, sometimes by a huge amount, because the load is at part-load conditions close to 99 percent of the time. That oversizing is the source of another downside of fixed-capacity systems.Duct joints should always be secured with #8 sheet-metal screws before seams are sealed with mastic.

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 …This seems to be how many green building pros ended up experimenting with a concrete-free assembly.

Whirlpool actually used a VIP that Owens Corning produced for a while (the Aura panel) in a high-efficiency refrigerator in …A typical two-stage condensing gas furnace has a turn-down ratio of less than 2:1. With most of these furnaces, the low-fire output is still 60% or more of the high-fire output. When a furnace with a low-fire rating of 60% is oversized by a factor of 1.7, you could cover 99% of the building’s heating needs at low fire.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.
