How to Make an Energy Efficient Floor Plan

As the world shifts towards more sustainable living, creating an energy-efficient floor plan is becoming a top priority for homeowners. Here's how you can design one.

By Trude Carlsen

Energy-efficient floor plans are no longer just a trend; they're a necessity. As concerns about climate change and rising costs grow, designing sustainable and cost-effective homes is more important than ever.

By incorporating energy efficiency, you can enjoy lower utility bills, a reduced carbon footprint, more natural light, and better air circulation.

In this post, we'll explore practical strategies for creating energy-efficient floor plans, from optimizing natural light and heat retention to incorporating sustainable building materials and smart technologies.

The Demand for Energy Efficient Homes

Energy-efficient homes are hot property right now. A 2022 Knight Frank survey revealed that 80% of people consider energy efficiency more important in their next home purchase than ever. Moreover, 20% of respondents were willing to pay a premium for an energy-efficient home.

This trend is reflected in property values, too. Data shows that improving a home's Energy Performance Certificate (EPC) rating from F to C could boost its value by a whopping 15%. That's an increase of up to £44,672 for an average three-bedroom semi-detached house.

1. Start with a Simple Layout

Simplicity is key when it comes to energy-efficient floor plans. A compact, straightforward layout is the way to go. Ditch those curves and stick with square and rectangular shapes. Here's why:

Save on materials: Square shapes use fewer materials, which means less waste and more savings
Heating and cooling: Simple shapes make it easier to keep your home cozy without racking up high energy bills
Flexibility: Square and rectangular rooms are easy to rearrange and repurpose as your needs change

By starting with a simple design, you're creating a space that's easier to build, maintain, and live in, all while saving energy.

2. Utilize Space Efficiently

By optimizing your layout, you can create a home that feels spacious and functional while keeping energy consumption in check. Here are some effective strategies to help you achieve this:

Open up your floor plan

Removing unnecessary walls can significantly improve air circulation and let natural light flow freely. This makes your HVAC system more efficient, as it doesn't have to push air through multiple small rooms. Plus, with more natural light, you'll rely less on artificial lighting.

Eliminate wasted space

Long corridors often become energy drains because they require heating, cooling, and lighting without providing much functional space. By eliminating these, you reduce the overall area that needs to be climate-controlled, which can lead to substantial energy savings.

3. Position Rooms Strategically

When designing your home's layout, consider where you spend most of your time. By placing rooms in the right spots, you can maximize efficiency.

Place frequently used rooms like the living room or home office on the south side to capture natural warmth from the sun, reducing the need for artificial heating.

Position less-used rooms on the north side, such as guest bedrooms or storage spaces. They'll act as buffer zones, shielding your warmer living areas from cooler north winds.

💡Expert Tip:

Keep your kitchen, bathrooms, and laundry room together to save on plumbing costs and minimize heat loss from hot water traveling long distances.

4. Maximize Natural Light and Ventilation

When designing your home, think about how you can maximize natural light and ventilation.

Position large windows on the south side to soak up sunlight and warmth. Use smaller windows on the east and west sides to balance the light and prevent overheating. This not only brightens up your home but also helps with natural ventilation.

To take it a step further, consider these strategies:

Add skylights or light tubes to bring natural light into darker areas
Use cross-ventilation by placing windows on opposite sides of a room
Install ceiling fans to circulate air efficiently

5. Use the Right Materials

Selecting the right materials is crucial in maximizing your home's performance. Here's how you can make smart choices:

Select materials with high-thermal mass

Materials like concrete, brick, and stone are great for regulating temperature. They absorb heat during the day and release it at night, acting like a natural thermostat.

For example, concrete floors can keep your home cooler in summer and warmer in winter, so you'll need less artificial heating and cooling.

Create insulation-friendly designs

Incorporate materials and designs that ensure good insulation. Consider using structural insulated panels (SIPs) or insulated concrete forms (ICFs) for your walls.

These options offer excellent thermal performance, helping to keep your home warm in winter and cool in summer.

Choose sustainable and locally sourced materials

When it comes to creating an energy-efficient home, it's not just about the final design – it's also about the impact you have along the way.

Choosing local materials not only saves on transportation costs but also boosts local economies. Opt for materials with low embodied energy, meaning they require less energy to produce and transport. This approach helps reduce your overall environmental impact.

6. Add Energy Efficient Features

In addition to designing an efficient layout and using the right materials, incorporating specific energy-efficient features can significantly improve your home's sustainability.

Solar panels are a powerful way to harness the sun's energy and power your home. To make the most of solar panels, position your roof for optimal sunlight by facing it south in the Northern Hemisphere and keeping it clear of obstacles. This setup makes it easy to add solar panels later if you want.

Additionally, consider upgrading to modern HVAC systems like heat pumps and geothermal systems, and properly place smaller ducts throughout your home to maintain consistent temperatures and reduce energy waste.

7. Future-Proof Your Design

Technology is evolving rapidly, so to stay ahead, it's essential to future-proof your home design. Here's how:

Make it easy to update energy systems: Create accessible spaces for energy equipment and add conduits for future wiring. This will allow you to easily upgrade things like energy storage later
Get ready for smart home tech: Plan for smart inverters, energy management systems, and good Wi-Fi coverage
Design flexible spaces: Create rooms that can serve multiple purposes. Add plenty of power outlets and tech-friendly areas for future gadgets. This keeps your home functional and sustainable as your needs change over time
