What Is the Best Shape for a Passive House?

A passive house has currently become the talk of the town with their efficacy and little use of energy for heating and cooling. It is mainly characterised by airtight construction and adequate insulation. During the tough winter, it uses solar energy to keep the house warm. This is how passive homes are beneficial for homeowners.

However, did you know that different shapes affect the efficacy of passive homes? Let us list down a few shapes and how they affect your passive home –

Different Shapes for Passive Homes

Before we begin with anything else, let us learn about the different shapes suitable for passive homes –

Cubes

This is the simplest and most efficient shape for passive homes. In fact, it is the most energy-efficient shape possible to maximise the benefits of passive homes. It is known for having a low surface area to volume ratio that helps in minimising heat loss. 

Rectangles

Rectangles are considered a bit more complex than cubes. Nonetheless, it is also a good choice for your passive homes. 

L-Shaped 

Lastly, another popular choice is only when they’re designed properly. To optimise solar gain, the house's long axis should be facing east-west. It is best to hire reputed passive house builders in Melbourne to get an idea of how the L-shaped system works. 

Advantages of a Compact Shape for Passive Homes

• Reduced heat loss: Because the walls and roof of a compact design have less surface area exposed to the outside air, they lose less heat. This is really important in the winter when the house is trying to retain heat.
• Improved insulation: Insulating a compact building is easier than a complex one. This is because there are fewer crevices and openings via which heat may escape.
• Increased solar gain: A compact design that faces south helps to maximise solar gain during the winter. Solar radiation can assist with natural home heating.

This is how a good shape and design play a crucial role in maximising the efficiency of passive homes. Make sure you hire reputed builders who can guide you through the right size and shape for your property.
