Are revolving doors the most energy-efficient doors?

As energy prices are set to continue to increase, energy efficiency is a key consideration for modern building design. Businesses and architects are continuously seeking ways to reduce energy consumption while maintaining comfort and functionality. It can be easy to overlook doors and door design, but it’s essential to choose the right type for your space.

Revolving doors are commonly found in commercial buildings, but are they the most energy-efficient choice? We’ll be exploring how revolving doors impact energy use, comparing them to other options, and looking closely at their role in sustainable architecture.

How do revolving doors improve energy efficiency?

So, what are revolving doors and what’s their USP? Revolving doors are designed to act as an airlock, minimising the exchange of indoor and outdoor air. Unlike traditional swing or sliding doors that create an open pathway for air to flow in and out, revolving doors are always partially closed (reducing the influx of outside air). This helps maintain internal temperatures and reduces the workload on heating and cooling systems.

A great perk of revolving doors is that buildings who use them lose far less heat during the winter and keep interiors cooler in the summer, leading to lower energy consumption.

The science behind energy savings and revolving doors

Let’s discuss the primary energy-saving mechanism of revolving doors – their ability to prevent uncontrolled airflow. In colder months, revolving doors keep warm air inside, reducing the need for additional heating. During summer, they prevent hot air from entering, easing the load on air conditioning systems. What’s not to like?

Traditional doors, particularly swing doors, can cause major heat loss, especially in high-traffic areas. Every time a standard door opens, conditioned air escapes, forcing HVAC systems to work harder. By reducing air infiltration, revolving doors can lower heating and cooling costs, ultimately reducing a building’s carbon footprint.

Revolving doors vs. other door types: an energy efficiency comparison

Not all doors are created equal when it comes to energy efficiency. Below is a comparison of revolving doors and other common door types:

1. Swing doors

Open fully when in use, allowing significant air exchange.
Poor insulation leads to high heating and cooling costs.
Common in smaller buildings.

2. Sliding doors

Provide slightly better insulation than swing doors.
Can be fitted with motion sensors to reduce unnecessary openings.
Still allow substantial air leakage, making them less energy efficient.

3. Revolving doors

Maintains a partial seal, preventing excessive air loss.
Provide continuous access without compromising indoor climate control.
More efficient in commercial spaces with lots of foot traffic.

Studies have shown that revolving doors can reduce energy losses a huge amount compared to swing doors, making them the preferred option for businesses prioritising sustainability.

Where should you install a revolving door?

Revolving doors are widely used in a variety of sectors to improve energy efficiency and manage airflow. Here are some key areas where they provide the most benefits:

Commercial buildings and offices

Reduce energy consumption by maintaining consistent internal temperatures.
Help businesses cut down on heating and cooling costs.

Hotels and shopping centres

Improve customer comfort by minimising drafts.
Enhance the entrance experience while contributing to sustainability efforts.

Hospitals and healthcare facilities

Maintain sterile environments by limiting external air contamination.
Improve temperature control in critical care areas.

Airports & transport sites

Help manage large volumes of foot traffic while reducing energy waste.
Improve passenger comfort by preventing extreme temperature changes at entrances.

Universities & public buildings

Support green building initiatives and sustainability goals.
Reduce energy costs while improving accessibility and comfort.

Revolving doors: what are my options?

We offer a range of revolving doors, each catering to the needs of individual sites. From power-assisted to automatic, there’s a revolving door that’s perfect for your business space. Here at EA, we offer:

Are revolving doors the best choice for every building?

While revolving doors offer clear energy efficiency benefits, they are not suitable for every building. Several factors should be considered before installation:

Foot traffic

High-traffic areas benefit the most from revolving doors.
Low-traffic buildings may not see significant energy savings.

Space availability

Revolving doors require sufficient space for installation.
Buildings with narrow entrances may find them impractical.

Accessibility considerations

While revolving doors are efficient, they can be challenging for individuals with mobility impairments.
Additional accessible door options may be necessary.

Cost implications

The initial investment for a revolving door is higher than other door types.
That said, long-term energy savings can offset the initial cost over time.

For buildings where revolving doors may not be practical, an alternative such as high-efficiency automatic sliding doors with air curtains can help improve energy efficiency.

Choose a revolving door for sustainability and energy efficiency

Revolving doors play a significant role in improving energy efficiency and reducing overall energy consumption. Their ability to minimise heat loss and maintain internal temperatures makes them a key part in a business’s energy strategy, and those looking to discover how a choice of door can lower their carbon footprint.

Their benefits in high-traffic areas and commercial spaces are undeniable. As sustainability becomes a greater priority in architecture, revolving doors will continue to be a preferred choice for energy-conscious businesses and institutions.

By investing in energy-efficient design solutions like revolving doors, businesses can reduce operational costs while contributing to a greener future. If you are considering ways to improve your building’s energy efficiency, Chat to our team to find out what’s best for your site.
