The sun is a natural and reliable source of energy. Solar Energy can be used to create electricity, heat buildings, heat water, distill water, cook food, dry food, dry clothes, and power electric vehicles. This course will focus on how the sun can heat homes by incorporating basic Passive Solar design strategies to provide from 20-90% of a home’s heating needs with little cooling penalties. Passive Solar energy can lower heating bills and allow PV (photovoltaic) systems to be downsized. Learn how the movement of the sun, siting, building shape, window placement, overhangs, porches, building mass, and insulation work together to warm and brighten homes
The course assumes that the attendee will have a grasp of basic building science such as the homes envelope, R-values, insulation, HVAC basics, and air tightness. If you do not, please complete the pt 1 - 3 of the Basics of Residential Green Building in Energy here • Basics of Residential ...
Learning Objectives:
1. Be able to describe how the seasonal movement of the sun affects various building surfaces throughout the year to bring in natural heat and light to improve the physical and mental health of occupants
2. Be able to use one web-based tools to quantify of Passive Solar energy for winter heat through south-facing windows to increase the well-being of occupants with a safer, more resilient home during extreme cold periods and how that ties into LEED BD+C V4 and v4.1 Residential Annual Energy Use
3. Be able to explain how siting, building shape, window placement, overhangs, porches, building mass, and insulation aids in cooling by minimizing summer solar gain while keeping the home safe during power outages and how that ties into LEED BD+C V4 and v4.1 Residential Annual Energy Use
4. Understand how the amount of insulation affects the percentage of a home’s heating load that can be provided from free, Passive Solar energy from the sun and how that ties into LEED BD+C V4 and v4.1 Residential Annual Energy Use

Is the main drawback of a higher south facing window percentage just too much heat? If my south facing shading can block out noon sun from May-September, wouldn't it still be a good thing to access as much of the free heat as possible. I am also planning thermal mass systems with interior wall being masonry and being on a concrete slab. Curious why most passive solar designs don't seem to have a higher percentage of windows south facing.

31:57 "Trying to convince people not to build basements"? maybe a video about basements? I was thinking that basements are god because of better insulation underground, but I also feel like the best house is one that will last for a a long time, this way resources aren't used up over and over, and a basement needs to be as durable as the rest of the house, but I did not find much information about that and I am left with a general feeling that basements start failing in some way before the rest of the house.

Passive solar homes can be built with almost any construction system such as ICFs, SIPS, or conventional stick framing. The inherent thermal mass of ICF can be a plus, and there are many ICF manufacturers to choose from based on your location. Slab-on-grade construction also has inherent thermal mass.

ivan2fast4u If I have 10% on 40sqm floor is 2x2 window... on south wall?!?! Are you kidding me? Assuming you mean a window that is 2 meters x 2 meters for your 40 square meter building, that is correct. To clarify, the maximum recommend south glass in latitudes of approx. 30-50 degrees North is 10% of the floor area. South glass above 7% requires additional thermal mass per the webinar.

Alternatively, the webinar was intended to provide house designers with basic passive solar concepts and tools to evaluate designs so perhaps have your draftsman watch it.

I want more information for those living in the equator (West Africa). I want to build a passive house, concentrating on cooling (the temperature year round is ~ 28°C +- 3°C).

"Modern Thermal Passive Solar is just starting to gain traction in most countries of Africa as the traditional architecture of buildings have passive heating and cooling features. Houses were built with thick mud walls for temperature insulation and depending on the region, the thatch roofing materials can range from corn stalks and straws to raffia palm leaves. Small or no windows were common in the old buildings to prevent direct solar radiation. Now modern buildings built with high thermal mass materials like concrete, need cooling and are retrofitted with air conditioners which are not energy efficient. Solar PV seems to be the adopted fix but costly to install. I think passive building materials and design can play a more efficient role for thermal comfort. The choice of building material and design depend on the region's local environment. I know much of Central Africa is hot and humid in the tropics, hot and dry in other parts so the location is really important. In the tropics, light thermal mass building materials like wood will help with passive cooling at night, and in the dry regions, concrete may still work. I did read a literature review on Passive Solar Systems for African countries that might have more information on the different passive design strategies that have been tried out in the last 10 years in different regions in Africa, I think it can also be helpful."

@@GreenHomeInstitute A square is a rectangle, but not all rectangles are squares. A mini-split is a heat pump, but not all heat pumps are a mini-splits; so they are NOT "the same thing." I find that many times the person answering the questions on behalf of The Greenhome Institute answer in short dismissive answers. Your answer does not meet your mission to "...empower professionals and homeowners to make healthier and more sustainable choices..." I would recommend that you reevaluate how you (as the institute) reply to folks, and maybe start by giving a better answer to this question.

@@MrNiceGuyMEGA08 Thank you for your feedback. We just increased our staff here so we may engage better. This session is not about heatpumps so the question was not specifically relevant but you are right. It is very true they are not the same, a mini split is a heatpump but some heatumps are ducted or ground source. We see more talking about ducted than ductless which is the opposite of what this person said. Thank you.

Thank you. Glad you appreciate the time that went into creating this educational video. The intent of this webinar was to teach about passive solar - specifically, anyone who would be designing a home. There was simply not enough time in the short one-hour course to also show more examples of built passive solar homes without sacrificing the educational aspect. There are many other GreenHome Institute webinars and videos that showcase examples of built homes that include passive solar and other sustainable technologies so please check those out. If you were referring to the presenters of the webinar, you can check out the individual websites to see built homes including Orlo Stitt's passive solar subdivision.

Does the overhang have to be built in?Can you install an awning instead?
@sunplans
@sunplans Год назад
Excellent question Marcia. Awnings of many types can also be used for window shading if a fixed overhang is not appropriate which could be in cases such as a tall south wall with lower windows, a gable end facing south, an addition, etc.

Energy efficient house design is of limited value when they are built in car-dependent green-field suburbs.
@sunplans
@sunplans 10 месяцев назад
Thanks for bringing up the importance of looking at a family's entire lifestyle energy footprint and not just the home! Personally, I moved from a very low-energy home in the country, but with long commutes, to a less efficient home (but still way better than average after our renovations) but with shorter commutes. And now I (and many of our clients) work from home more often to even further reduce the carbon footprints. So, while I don't think I'd say that an energy-efficient house design is of limited value, I'd agree to keep the big picture in mind when making housing and life-style choices.
