Thermal batteries: how to passively store heat

What is a 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 ...

R values and insulation performance
Efficient home design

Understanding thermal performance

First published in ecoHouse Canada The thermal performance of wall assemblies and insulation products has long been characterized using R-value, a metric which describes thermal resistance. While R-value is useful, it doesn’t tell the whole story about heat flow through building enclosures such as walls and roofs. Rece...

Energy modeling simulation of heat loss through thermal bridging
Efficient home design

What is a thermal bridge and why is it so important to break it?

It is easy to look at the R value rating of a material and assume that our entire wall assembly matches it uniformly. But when you factor in the thermal bridges caused by framing materials and any discontinuities in the wall structure, you can also quickly deduce that this is not the case. It doesn't take expensive equ...

Solar thermal collectors

All about solar thermal collectors

What is a solar thermal collector? A photovoltaic (PV) solar collector converts solar radiation into electricity, but a solar thermal collector is much simpler than that. It refers to a device that collects heat directly from solar radiation. That can be as simple and rudimentary as water being pumped through a black t...

Lithium-ion solar home batteries

Home battery systems have recently improved in two substantial ways, and the first big improvement is in the batteries themselves. Lithium-ion batteries on the market today are much more robust and functional than the lead-acid batteries we have relied on in the past. Discharging a lead-acid battery beyond 50% capacity...

Net zero energy homes Canadian pilot results

Net Zero Energy Homes pilot program goals The goal of the R-2000 Net Zero Energy homes pilot program in Canada was to improve the performance standards of homes, and to raise awareness of energy-efficient green home building techniques among builders. Through participating in this pilot project, every builder became li...

Product of the month: Solar water heater with overheating protection

  Solar thermal panels in cold climates are at risk of freezing in winter, so in the North, we use a glycol mix as a heat transfer fluid. This prevents panels from freezing but introduces new problems in the summer months when they are at risk of overheating.  There are two main types of residential solar thermal heate...

How to design for thermal comfort in a home

Have you ever noticed that at times you can feel cold in your home even though the air temperature is exactly where you like to keep it? That's because, contrary to what most of us think, air temperature is not the main factor that determines human comfort in a building. To illustrate a point, let's start outdoors. I m...

Concrete floors and timber frame as thermal mass
Efficient home design

The pros and cons of thermal mass in buildings

Materials in a home that act as thermal mass are things like concrete, masonry, ceramic tiles, even a large volume of wood like timber frames. All materials inside the insulated building envelope will store and release heat, the more dense they are the more pronounced the effects are.  Intentionally adding greater amou...

Installing doors & windows for the best performance in high efficiency homes, LEED & Passive House

The importance of installing doors and windows correctly: Window and door openings are breaches in a building envelope that need to be carefully managed in order to prevent moisture damage and air leakage in homes as well as to save energy. Water leaks from around windows and doors are the visible result of a poor inst...
