Light inside the home is more valued than ever before with residents taking
advantage of the building’s orientation for energy efficiency, including views
and inviting nature into their homes, and enjoying free-flowing spaces.
Increased levels of natural daylight aid Vitamin D and serotonin levels
in the human body, both of which support mental, spiritual and physical health,
while depression, anxiety and ill-health are the consequences of reduced levels
of natural light.
Windows are the primary entry point for natural light in any living
space; the size of the windows would, therefore, impact the amount of light
entering the room.
Getting the window size, location and specification right is critical to
maintaining the desired comfort levels in the home. Glass selection should be
preceded by due consideration of all variables including balancing the benefits
of natural light with the side effects of heat gain, heat loss and glare. These
elements can be controlled with shading techniques such as external Venetian
blinds, proper window placement and orientation, and the use of energy-efficient
Using ordinary single glazing on large windows will leak too much heat
and won’t meet the compliance requirements of energy regulations. Small windows
are typically used on 6 Star houses to get a higher energy star rating. However,
homeowners can still choose larger windows for their homes using double or even
triple glazing to achieve the same 6 Star rating or even higher, while ensuring
light, views and a sense of space.
The CSR Viridian research underlines the importance of well-placed
windows in maximising the entry of natural light in a home, and contributing to
the well-being of the residents.
Paarhammer double and triple glazed windows and doors have been setting
the benchmark in energy efficiency in Australia for over two decades.
