What Is The Most Efficient House Shape? (2024)

HOUSE SHAPE THAT IS THE MOST ENERGY-EFFICIENT

In deciding its potential energy-efficiency, the shape of a house is a major factor. The geometric shape limits how effective energy conservation is in the building. That being said, it is important that the surface area of the home is as minimal as possible, leading us to the form of a sphere.

For most people, constructing a spherical house isn't very practical. Nevertheless, have it built to have the least amount of surface area if you want a highly energy-efficient home. Fortunately, in terms of energy-efficient shapes, the better built the building, the lower the cost of construction since there would be fewer walls, foundations, and roofs in such a design.

Samples of Energy-Efficient House Shapes

Across the entire surface area, the theory behind the energy efficiency of shapes revolves around heat gain or loss. Via thermal loss, the system concerns preserving the temperature balance between outside and inside. The indoor temperature will eventually begin to come close to the outside temperature if the weather is cold outside. Air circulation can also impact the house's heat gain or loss.

The smaller the surface area, the less heat would be radiated by the structure, and that means less heat loss. So, let's take a look at a couple of the most energy-efficient house shapes.

Dome: Dome-shaped houses with their widest area at the base are half spheres. In the corners, frameworks lose energy. This shape has no corners, so winds flow smoothly over its surface, leading to little or no changes in air pressure around the building. This streamlining results in less air penetration, which is key to the energy efficiency of the building. Air ventilation can be achieved most effectively because air drag is not caused by corners. For the least amount of surface area, this design allows for an optimal living room. A dome also provides for the circulation of natural air , especially when at the apex of the arch there is a venting cupola. Without the need for fans, warm air rises and is released.

Cube: In most homes, this shape is what we normally see. It has the same length along all its sides, so it can still provide proper air ventilation despite having four corners, but without the efficiency of a dome-shaped building. This shape is lightweight and makes energy efficiency fair.

The more floor space relative to the living space, the less functional the structure would be. A house with an irregular shape is less effective because it has dormers, bump-outs, turrets, or bay windows.

FAQs

What Is The Most Efficient House Shape? ›

Simple rectangles or squares, 2 rooms deep, with the important rooms (bedrooms, living areas, kitchen) on outside walls. All rooms having windows on two sides for cross-ventilation and light. You can still have a somewhat open floor plan, but I wouldn't go overboard with that.

What is the most efficient house shape? ›

#1 Geodesic Dome Homes

First on our list of energy efficient house designs is the geodesic dome home. The first geodesic dome structure was designed by engineer Walther Bauersfeld for a planetarium shortly after the First World War.

Which shape house is best? ›

Square shaped plot, buildings and rooms are considered ideal for a number of reasons. A slightly rectangular structure is also well appreciated. Distribution of space becomes easy in a square or moderately rectangular building. Positive energy travels well within its walls.

What is the most energy efficient style of house? ›

Earth-Sheltered, Straw Bale, Log, and Manufactured Homes

Earth-sheltered homes can be built underground or bermed, and—when well designed and built—can be comfortable, durable, and energy-efficient.

What building shape is most economical? ›

The square is by far the most efficient and cost effective use of space. First of all, we live in a world where furniture and building materials are cut with 90 degree angles.

What is the strongest shape to build a house? ›

The triangle is the strongest to as it holds it shape and has a base which is very strong a also has a strong support. The triangle is common in all sorts of building supports and trusses.

What is the cheapest shape of house to build? ›

A ranch-style house is generally more affordable to build because it has an easy, open floor plan and is traditionally available in a rectangular or U-shaped layout. Many have a dedicated patio space for homeowners to enjoy or easy outdoor access. Maintenance usually costs less for a ranch-style house as well.

What is the most desirable facing house? ›

South-facing houses are also considered desirable. If a condominium or the front of the house faces south, it receives natural wind throughout the hot and lengthy rainy seasons. There is ample sunlight entering the rooms or the house during the afternoons.

What is the strongest house design? ›

Architecturally speaking, triangles are the strongest house shape. Think of some of the world's most famous architectural marvels: the Louvre Pyramid, the Great Pyramids of Giza and the Eiffel Tower.

What is the perfect home layout? ›

Ideally, to provide the best layout for your family, there should be one bathroom for every two bedrooms in the house. Homeowners who entertain frequently should choose a house layout that has a full or a half-guest bathroom near the living area. The guest bathroom should be downstairs in homes with multiple floors.

What is the best shape for a passive house? ›

Buildings with a simple geometrical shape, such as cuboids or cubes, have less surface area in relation to their volume and thus a better S/V ratio than buildings with numerous protrusions, oriels or dormers.

What drains the most energy in a house? ›

What Can I Unplug? These Household Items Cost the Most Electricity
  • Cooling and heating: 47% of energy use.
  • Water heater: 14% of energy use.
  • Washer and dryer: 13% of energy use.
  • Lighting: 12% of energy use.
  • Refrigerator: 4% of energy use.
  • Electric oven: 3-4% of energy use.
  • TV, DVD, cable box: 3% of energy use.

What is the most cost efficient style of house? ›

On a per-square-foot basis, pole barn houses and barndominiums are the most affordable at around $50 to $160 per square foot. Other inexpensive home types include modular homes, tiny homes, shipping container homes, and standard one-story ranch homes.

What shape is best for a house? ›

A cube is the most reasonable, compact shape for a home to minimize heat transfer. Of course, other factors come into play, such as optimizing glass area on the south-facing wall and ensuring that sufficient light can penetrate to the interior spaces, often making a rectangular shape more desirable than a cube.

What is the most durable house shape? ›

We found round houses were more resistant to strong winds than box-shaped houses, and houses with pyramid hip roofs were more resistant to strong winds than houses with flat roofs if other attributes of the houses were kept the same.

What is the weakest shape for a building? ›

If you Google the weakest shape, the most common answer is the circle. Many variables will factor here as well. As it turns out, there really is no simple, one-size-fits-all answer to the question. Knowing if we need strength for support or containment is an example of what needs to be known to answer the question.

What shape is the most space efficient? ›

The hexagonal shape allows for efficient use of space, maximizing storage capacity while minimizing material usage. This remarkable hexagonal structure has inspired mathematicians to study its properties and has even been used in architectural and engineering designs to optimize space usage and structural stability.

What is the most cost efficient building shape? ›

The reason most commercial designs are rectangular, or square, is because they are easier, faster and more economical to build out of ordinary materials – stone, concrete, brick or wood. Square and rectangular shapes are also exponentially easier to reconcile, and there's usually less waste.

What is the most efficient shape and why? ›

The circle is the simplest shape which mobilised humankind with the invention of the wheel. It's the most efficient shape as well, a spherical object has no stress points as every part is equal.
