Building codes, space and style: ArchiPro explores the key differences between vacuum elevators and traditional lifts for New Zealand homeowners and specifiers.
What is the difference between a vacuum elevator and a traditional lift?
While both elevators will take you between floors, it’s important to note that vacuum elevators and traditional lifts operate differently. Pablo Brizio, Director of Vacuum Elevators, explains, “A vacuum elevator uses air pressure differences created by a suction motor to move the cabin inside a cylindrical shaft, while traditional lifts use cables, pulleys or hydraulic pistons powered by a motor.”
These differences lead to several practical benefits. For instance, vacuum elevators don't require a pit or machine room, often consume less energy, and require less maintenance. “Additionally, their oil-free operation makes them a more environmentally friendly option,” adds Pablo.
Another appealing feature of this elevator type is its ability to blend into modern house designs, thanks to a compact profile and minimal shaft requirements. “They allow for more flexibility in placement within the house,” says Pablo.
Space requirements and structural considerations
When considering lift installation in your NZ home or project, it's important to factor in space and structural requirements. "Vacuum elevators require minimal structural changes, by fitting directly onto existing ground floors," notes Pablo. "They are lightweight, requiring less building works to the house"
In contrast, he advises traditional lifts often require significant structural considerations, including special foundations and the provision of a pit. This can have a flow-on effect with increased renovation costs and time.
The rising need for in-home elevators in NZ
Pablo notes the demand for in-home elevators has been on the rise, driven by a desire for accessibility and mobility solutions.
"Yes, we're seeing an increasing demand, especially from homeowners looking to future-proof their homes," he says. “This trend is particularly significant for people who require assistance with mobility [and now] don’t need to relocate to another house or neighbourhood.”
Pablo continues, “We found the COVID-19 pandemic, in particular, reshaped many aspects of home design, especially with home accessibility, which led to an increased interest in lift installations to accommodate people’s changing needs over time.”
Vacuum vs. traditional lifts in aesthetics
When it comes to style, vacuum elevators meet the brief with its undisruptive, cylinder design. "Vacuum elevators offer a distinctly modern, sleek and transparent look." On the other hand, "traditional lifts can vary but are often more enclosed and less visually open,” adds Pablo. “Which some homeowners might find less appealing.”
As for design flexibility, vacuum elevators emerge as the clear winner. "They offer more design flexibility due to their smaller footprint and structural requirements."
This flexibility gives architects and homeowners more options for including an elevator into the overall design, making it a practical choice for various architectural styles in New Zealand.
Building codes and consent issues in NZ
Navigating building code and consent issues is often challenging. But according to Pablo, vacuum elevators have an advantage. “Vacuum elevators often have simpler consent processes due to their self-supporting structure and minimal requirements, which can streamline the approval process compared to traditional lift installations,” he says.
While both vacuum elevators and traditional lifts can add value to your home and provide an important mobility solution for homeowners in multi-level residences, the visual appeal and minimal structural requirements of vacuum elevators offer specifiers a simpler design solution that meets their clients’ needs today and in the future.
