Passive Solar Design - What is thermal mass?

[@SvenvandeBergh]

How is this related to IR-heating and solar panels?

[@Lawiah0]

Insulate the thermal mass on the Outside (cold side). see Dry Stacked Concrete Blocks

OK explanation of winter benefits but a missed opportunity to up front clearly explain the benefits and mechanisms of thermal mass cooling (gets there in the end though) and the role of thermal mass in sub-tropical climates when its winter and not humid and in summer when days are still way hotter than the nights and thermal mass will benefit even in SE QLD..

Thank you

Want if there is no sun to absorb ...can then heat be absorbed from the heater rather

In the Heart of Vancouver Island BC Canada passive videoskzbin.infovideos Material used Port Alberni's first Passive house (Passivhause) build in the heart of Vancouver Island British Columbia Canada. Passive House(Passivehaus) is considered to be the most rigorous voluntary energy-based standard in design and construction industry today. Passive house buildings consume up to 90 percent less heating and cooling energy than conventional building. The use of Passive House design software was used to gain the specs required to meet the performance standard for this location. House was constructed well above the current standards as outlined in the B.C. Building Code. Footings were widen to 36 inches(914 mm) due to low bearing soil conditions and additional rebar reinforcement added. 30 inch high (762 mm) high reinforced walls . Course sand placed inside foundation walls and mechanically compacted. Three layers of four inch *102 mm) thick Expanded polystyrene foam sheets with all joints staggered and tape were placed on top of compacted sand. The three layers of foam have insulation value of approximately R 50. A 20 mil layer of poly was placed over the E.P.S. sheets and taped and sealed. Four inches(102 mm) of 30 m.p.a fiber reinforced concrete was placed to form a slab over the foam based. Slab is isolated from concrete stem wall with four inches (102 mm) of E.P.S. to prevent thermal loss. All cold water lines are buried in the sand to keep them cool, hot water lines have been placed in the center layer of foam insulation to minimize heat loss. Wall plates compress to heavy beads of acoustic sealant between layers of vapor barrier to prevent air movement. The walls are double stud configuration set at 24 inches (610 mm) on centre and plates are spaced in a manner that yield a 20 inch (508 mm) thick wall. 1/2 inch (12 mm) standard plywood sheathing with Mento 1000 a three layer airtight vapor open house wrap( far superior to common house wraps) with 1/2 inch(12 mm) pressured treated plywood rain screen battens form the exterior surface. Intello smart vapour barrier was installed one third in from the inside wall to prevent condensation in this climate. Triple pane argon filled windows meeting passive house standards from Euroline were placed mid wall to reduce wind wash heat loss. All window openings have been splayed at 45 degrees to give a full wide angle view. Almost all the wiring and plumbing was kept inside of the vapor barrier envelope to minimize air leakage. Passive house standard requires air leakage not to exceed .6 Air changes per hour at 50 pascal. Zehnder comfoair 200 HRV has been installed with a 1000 watt air preheater .(92 percent heat recovery rate) House has been pre- plumbed for a heat pump water heater reducing domestic water heating cost significantly. Garage has been pre-wired for 40 amp/240 volt electric car charging station. House to be equipped with heat pump condensing dryer which requires no external venting,only a water waste line.

Give a simple answer geez

[@seigeengine]

So let's spend almost 14 minutes poorly explaining a simple concept. Brilliant.

[@callmeswivelhips8229]

Seriously lol

[@ziabashir]

Appreciate someone efforts teaching or learning,

That woman really had no idea what she was talking about. Just listen to her first sentence. "WOW, I have no idea how to explain this!" Of course this is followed by her saying the same thing over and over in different ways. Bullshitting doesn't end after high school I guess. The guy was much much better.
