"Passive is the new active"

Couple weeks ago, I happened to mention "passive house design" on one of my writings. Maybe you didn't realise since I mentioned only a little bit.  But now that you're here aren't you curious about it?

I found this term during my research on other topics and I found it pretty interesting.

According to my research, passive house refers to a standard where a house is considered energy efficient, particularly in its heating and cooling system. This, of course, has something to do with sustainable living. The purpose is to minimise energy consumption and thus gas emissions (that is said to be 48% from buildings on their own). Given this figure, anyone can tell that building is indeed one of main contributors when it comes to climate change. Sad? :(

Then there was this solution to square building energy needs without damaging the environment (not that much, at least). With a concept of providing efficiency in energy consumption, passive house happen to be an intriguing option for construction industry. This concept was first introduced in Germany and its popularity began to rise ever since.

Some of its components including:  insulation, airtightness, heat recovery, solar heat gains, solar shading and incidental internal heat gains. As a result, 90% of reduction in heating and cooling is expected when the design is utilised.

So here's why passive house design can bring the best of your house!

It fundamentally addresses the climate crisis imperative

Passive house can slash energy demand for buildings dramatically that it can mitigate the worst effects of climate change in this modern world. Meaning, no matter if it's for the rich or poor, everybody gets the benefit.

Affordable

To get the stuff done architects and builders used to pay a higher initial cost during its introductory stage. Lucky for us now, this cost has shrink to as low as less than 5% due to better optimisation in its subsequent projects. Many people have adopted this standards and guess what, reduced energy usage leads to lower energy bills. Not only it is becoming more and more affordable in terms of initial cost, it is also offering us more savings in coming years.

Produces the most comfortable and healthy indoor environments.

With air tightness, continuous insulation, high quality windows and other measures, passive houses offers its occupants  the most comfortable, quiet and healthy environments.  Maximised ventilation and windows produce filtered fresh air that flows to  living and working spaces, making the indoor air free of dangerous contaminants.

 It enables nearly zero energy buildings

Building specific renewable energy production can be complicated and expensive. With a building’s energy demand minimized with Passive House, renewable requirements become far smaller, more affordable and achievable.

It locks in energy savings for future generations

Unlike renewable energy production or energy saving machinery that requires active maintenance and replacement, Passive House emphasizes things like insulation, air tightness and external shading that will save energy today, tomorrow and everyday into the future without significant maintenance or replacement costs.  Consequently, any lost opportunity to optimize performance with an investment in passive measures will become a much bigger future liability in our efforts to decarbonize
