How to design for thermal comfort in a home

...heating costs. There is also the matter of conductivity - a wood floor and a concrete floor at the same temperature would feel very different since concrete conducts heat much better, making it seem either warmer or colder than a wood floor of the same temperature. It is important to note that including in-floor heat...

Slab on grade or crawlspaces, which is better?

...heating, it does not blow dust around your home. So it offers an advantage for cleaner indoor-air quality than a crawl space foundation. A polished concrete floor with a non-toxic finish is the most durable and healthy flooring material you can choose for a slab on grade foundation. The only downside is that it can b...

Ecohome Demo House: High performance, affordable cost

...heating systems and the utility bills that come with them. When a design team focuses on heat retention rather than heat generation, the net result can be a home that is cheaper to own and operate; not far into the future but right from day one. Added building costs are offset monthly by lower heating costs, and expe...

Zero Carbon Homes - The S1600 Prefab Eco Home gets affordably Close

...heating, cooling and ventilation – become the next big design component that affects the total carbon footprint. Heating systems for this house are the choice of the buyer; in this case we chose to use an electric radiant floor (which is partly solar-heated, see more below) and a mini-split heat pump for heating and ...

Properly insulating basements and concrete slab floors

...heating season, there will be much more heat loss through above-grade walls than those below. Therefore, with one wall and two rates of heat transfer, this leaves the dilemma of insulating more than you need below, or less than you need above. There is the option of beefing up insulation at the level above grade; how...

Solar heating and energy generation

...heating Passive solar heating is the concept of using home design and orientation to collect heat directly from the sun. No panels, no wires, no tubes, that’s why it’s called ‘passive’. By having 60% of your windows facing south and building your house within 15 degrees of the east/west axis, you can reduce your he...

The pros and cons of thermal mass in buildings

...heating and cooling. Heat security: Having significant thermal mass in your home can be a big advantage in winter in the case of power outages, as virtually all commonly chosen heating systems rely on electricity to at least get started. If your house has heat stored in mass inside the building envelope, it will slow...

Efficient home design, or how to design a home to use less energy

...heating strategies here. A house with 60% of its windows facing south ( passive solar ) may have its heating requirements reduced by as much as 25% for virtually no cost. It is important that it be properly-designed to avoid overheating though, or you will negate any heat savings with air conditioning in the summer. ...
