Which type of house is most energy-efficient? - SEHBAC (2024)

2021 has been a real turning point for many homeowners across Essex and Suffolk who wish to improve their homes’ energy performance. But with The Future Homes Standard only a few years away, all new and existing homes must prepare to be more energy efficient and ‘zero-carbon ready’ by 2025.

Sustainability and looking after the environment are crucial considerations at SEH BAC. So, let’s look at which type of house is the most energy-efficient, whilst addressing a few more of your insulation concerns along the way.

What is the most efficient building shape?

Which type of house is most energy-efficient? - SEHBAC (1)

When it comes to the most efficient building shape, uncomplicated dome and cube structures retain the most heat. This is because the air can circulate more efficiently around a dome whilst a cube has the smallest surface area to floor area ratio, so it loses minimal amounts of heat. Typical examples of cube shaped homes include Art Deco buildings, 1930s semi-detached houses, 1990s new build properties, and modern minimalist homes.

Are single storey homes more energy-efficient?

Typically, single-storey floorplans are the most energy efficient. With less rooms to heat, they are easier to maintain an even temperature through winter whilst staying cool in summer. However, it largely depends on the property’s size, as smaller two storey homes with the same square footage can sometimes work out just as or more energy efficient than single storey households. Heat also rises, so there may be less need to heat second level rooms during colder months too.

What makes an energy-efficient house?

Whether you’re thinking about making an old building more efficient or want to know more about what to look for in a new build property, essential elements of an energy efficient house include:

  • Energy Performance Certificate (EPC)

Ideally, you want an EPC score of band D or above.

A Guide to Energy Performance Certificates

  • Renewable energy sources

Energy generated from natural sources, e.g., Solar power, renewable electricity supply, wind energy, air source heat pumps, biomass heating systems, solar heating, and hydroelectric systems.

Seven ways to power your home with renewable energy

  • Modern double glazing or secondary glazing

Single glazed windows and doors are very poor insulators, which, in turn, means astronomical energy bills. Modern double glazing (like ours!) can offer energy savings as high as £110 per year. Whilst secondary glazing is often the best option for upgrading inefficient old windows for those living in listed buildings or conservation areas where double glazing installation is prohibited.

  • An insulating front door

Front doors are often taken for granted but neglect them at your peril! Forming an essential barrier between your home and the good old British weather, new doors currently require a minimum energy rating of E or a U-value of 1.8 to comply with Building Regulations. Don’t forget new standards for energy efficiency are looming, where the predicted minimum energy standard for doors is 1.0. So, it’s essential to bear this in mind when choosing a replacement front door.

Each front door material available at SEH BAC is chosen for outstanding energy efficiency. The most efficient material we offer is composite, closely followed by uPVC, aluminium, and timber.

  • High performance cladding

Adding cladding to your home is basically putting an extra skin on the outside of it – like a permanent winter coat for your home that performs all year round! With up to 35% of heat inside escaping through the walls, quality cladding (like ours!) could be just what your home needs to stay warmer for longer. Offering superior PVC and coastline cladding products suitable for a wide range of homes across the South East, increasing your homes’ aesthetic appeal is a free added extra!

  • Other things to consider

  • Cavity wall insulation
  • Solid wall insulation
  • Loft insulation
  • Draught insulation
  • Upgrade your boiler
  • Programmable thermostats / Smart thermostats
  • Energy efficient appliances
  • Replace light bulbs with LED bulbs

What is the most energy-efficient form of energy? ›

In short, wind energy offers the most economical, environmental, and logistical benefits of any energy source.

Which is the most energy-efficient option used at homes? ›

Active solar heating may be the most efficient option for heating your home.

Which areas of the house are the most energy-efficient? ›

Try to have seldom-used rooms, such as closets, bathrooms, utility/storage rooms, or stairs act as “buffer zones” on the east and west sides of the home to help keep heat out of the primary living areas. It will save on your heating/cooling costs.

Which is most energy efficient? ›

Compact Fluorescent lamp (CFL) is more energy efficient among all the given options.

What is the most efficient energy system? ›

The most efficient forms of renewable energy are geothermal, solar, wind, hydroelectricity and Biomass.

Which energy system is the most efficient? ›

The aerobic system can use carbohydrates, fats, or proteins to produce energy. Energy production is slower, but more efficient than the other two systems. As you can tell by the name, the aerobic system requires that there be adequate oxygen available to the working muscles.

What kind of energy is 100% efficient? ›

Electric resistance heating is 100% energy efficient in the sense that all the incoming electric energy is converted to heat. However, most electricity is produced from coal, gas, or oil generators that convert only about 30% of the fuel's energy into electricity.

Which type of energy is best? ›

Out of all energy resources, we consider green power (solar, wind, biomass and geothermal) as the cleanest form of energy. So, if we were looking at clean energy on a spectrum, these would be farthest from “dirty” or emissions-heavy energy.

What is the best energy efficiency? ›

Appliances are tested for how much energy they use during typical use. This gives them a rating on a scale of A to G, with A being the most efficient product of its class, and G being the least efficient. Some appliances (e.g. ovens) use an older scale, from A+++ to G, with A+++ being the most efficient.

What is a more energy-efficient home? ›

Building an efficient home, or renovating a home to make it more efficient, means choosing thermal insulation materials for walls, ceilings, doors and windows, and using renewable sources of energy — such as solar panels — and electricity storage systems.

What is the most used type of energy in the home __________________? ›

Electricity and natural gas are the most-used energy sources in homes.

Home efficiency

If your home's energy efficiency is a concern, you may want to consider a two-story house. For the most part, a typical two-story home uses less energy than a one-story home of equal square footage. This is thanks in part to smaller foundation and roof space.

What is the highest energy rating for a house? ›

At the highest end of the scale, a house with an energy rating of 10 means no artificial heating or cooling is required throughout the year.

What is the best energy source for your house? ›

Natural gas, by definition, is more efficient overall than electricity, so if that is what you are going for—and your home isn't already natural-gas compatible—check with your local gas company to find out whether conversion to natural gas is possible.
