The pros and cons of thermal mass in buildings

...thermal mass in it, any such savings pretty much cease to exist because it might take the entire day to drop even a full degree. The disadvantages of thermal mass in homes: Let's speak to the potential downsides of thermal mass first - if a home is regularly left empty for several days at a time or if you keep a co...

Gabion walls can be used for building homes

Gabion Walls - what is a gabion cage & how to build with them?

Gabion walls are retaining walls built by stacking stone in a gabion cage or gabion basket that can serve many purposes but are most often used to create tiered or leveled ground in gardens. They are rectangular baskets of metallic lattice filled with stones and their origin dates back to war times when they were er...

R values and insulation performance

Understanding thermal performance

...thermal resistance [LTTR] metric, but also exaggerates the effects of temperature. A recent study by RDH which looked at conventional roofs found that the thermal mass of the insulation, in addition to the assembly itself, can also impact in-service heat flows. Thermal mass stores heat energy and provides a buffering...

Thermal batteries: how to passively store heat

...thermal battery? Thermal mass of any kind can by definition be called a thermal battery, as it has the ability to store heat. In the context of a house, that means dense materials like bricks, masonry and concrete. Even a jug of water sitting in a sunny window is a thermal battery of sorts as it captures and later re...

...thermal radiation. Darker materials with heavy mass like concrete, stone or brick will absorb the most heat. For walls you can simply add a second layer of drywall (or more), if you want to keep a traditional look. A high quality window choice is important, and to truly invest in this concept you are best to install ...

7 key principles for an abundant greenhouse

...Thermal Mass An extremely important part of solar greenhouse design is planning enough thermal mass , either via water, masonry or soil underground. This can be as simple as adding water barrels or you can upgrade by incorporating a Ground to Air Heat Transfer ( GAHT) system . Even a small greenhouse collects as much...

Solar Electricity Generation & Storage with no Batteries, Azelio
Renewable energy

Azelio Solar solutions combine electricity generation & storage without Batteries

...thermal collection is quite simple; it can be passive solar home design , or solar air heaters or solar thermal water heaters. Heat can easily be stored in thermal mass (also known as a thermal battery ), which is nothing high tech – concrete, water, stone, wood, etc., are all examples of thermal mass. As a general rul...

The Kenogami House: Energy systems at the cutting edge of innovation

...thermal solar panels: It may seem counterintuitive at first, but there is strong case supporting the use of PV panels for heating water over thermal solar systems, though recent innovations such as Viessman's Vitosol solar thermal water heater has revived that debate. Photovoltaic systems in the mechanical room ©...

...thermal battery by storing and releasing heat , which helps balance temperatures in both summer and winter. Such quantities of heated thermal mass inside the building envelope also provides heat security in the event of a power outage, by slowly releasing its heat over the course of days. Raft slabs can be heated wit...

"If the Earthship were a gasoline engine, Thermal Wrap and double or triple greenhouses would be fuel injection. I am ready to race any conventional heating system." - Michael Reynolds, Earthship Biotect . Thermal mass does st...
