Having blinds on the interior of a building is something that comes almost as second nature when thinking about how to create a barrier for the sun or privacy. It’s something we’ve always done in New Zealand and one we continue to do, almost as a habitual part of building designs.
However, it’s not something that’s commonly done globally and there are very valid reasons for this. “In New Zealand, we seem to be somewhat stuck on the idea that the way to deal with sun is once it has already entered a building, rather than before it has the chance to enter,” Lahood’s Clayton Sceats says.
“Overseas, people stop the sun before it enters a room, which has a host of benefits, and it is why exterior blinds come into their own because the heat of the sun is stopped before it has the chance to enter a building and increase the loads on heating or cooling.”
In Australia, it has been common practice to install exterior blinds for a couple of decades, Clayton says, and for much longer in Europe and America.
“For a lot of building designs that aim to be sustainable or meet some form of green rating, solutions such as exterior blinds are becoming a prerequisite and is something we slowly starting to see more of in New Zealand as people become aware of what is available and what can be achieved.
