A distinguishing feature of the A+ Home is that it incorporates two concrete masonry walls whose thermal mass properties ensure energy and financial savings as well as the added benefit of a moderate, comfortable internal temperature.
By taking advantage of concrete's thermal mass, in combination with an appropriate level of insulation and glazing, the masonry walls regulate internal temperatures to provide a healthy and energy efficient living environment throughout the year.

In summary
- Building cost estimates show that the A+ Home, with its two concrete masonry walls, is an affordable option.
- Thermal modelling illustrates that by using the thermal mass of concrete masonry, in conjunction with appropriate levels of glazing and insulation, the A+ Home harnesses the sun's solar energy to help reduce energy demands (heating and cooling) throughout the year.
- By lessening internal temperature fluctuations, concrete masonry's thermal mass also helps reduce the potential for mould, fungi and dust mites to create a healthier living environment.
- The maintenance costs associated with the A+ Home's concrete masonry are lower compared to alternative lightweight materials. It does not require painting and will not rot, making it essentially maintenance free.
- Concrete masonry is also inherently fire resistant.
- High mass walls such as concrete masonry walls repress sound transmission from one side to the other, specifically low frequencies are significantly better absorbed with high mass walls in comparison to light weight walls.
