How to choose curved automatic doors for luxury hotel lobbies: 50% noise reduction & stable temperature control

The OREDY ES200CD curved automatic door system cut lobby noise by 50% (from 55 dB to 28 dB) and stabilised lobby temperature to within ±2°C at Barcelona Royal Resort Hotel — eliminating €22,000 in annual energy waste.

Project Overview

The Problem

A waterfront five-star hotel with 1,200+ daily guests had a fundamental mismatch: the original straight automatic doors sat against a sweeping curved glass facade, leaving gaps that could never properly seal. Every time the doors opened — and they opened constantly, triggered by sidewalk pedestrians and sea wind — the lobby filled with noise and outside air.

The false trigger rate was running at 25%, meaning one in four door openings was unnecessary. The AC system was working 40% harder than designed to compensate. Noise measurements at the concierge desk clocked 55 dB — louder than a standard office. Guest review platforms had flagged the entrance experience as a consistent source of complaints, and the property calculated that €22,000 per year was being lost to excess energy costs alone.

What We Did

We custom-fabricated the ES200CD frame to match the hotel's exact facade radius — no off-the-shelf curved door fits a bespoke architectural arc. The drive system uses a silent motor that eliminated the mechanical impact sound entirely. High-precision directional sensors were calibrated to filter out pedestrians on the pavement and wind movement, bringing the false trigger rate down to 5%. High-density perimeter weather sealing was installed around the full door edge.

The complete installation was carried out between 11 pm and 6 am on three consecutive nights. No lobby access was interrupted.

Results After 4 Months

Ambient noise at the concierge desk dropped from 55 dB to 28 dB — that is quieter than a hotel library. Lobby temperature now holds within ±2°C regardless of outside conditions. Energy consumption for the lobby HVAC fell by 40%. Guest complaints about the entrance dropped to zero, and the hotel's average online review score increased by 0.4 points. Carlos García noted at the 90-day review: "The door now matches what the building was designed to be."

Key Technical Specifications

Frequently Asked Questions

Q: Can you fabricate the frame to our exact building radius — we have a non-standard curve?

A: Yes. The ES200CD is built-to-order. We require the radius measurement and a facade drawing or on-site photo. We confirm fabrication feasibility within 48 hours of receiving the specs.

Q: Our hotel is in a coastal / high-wind area — will the sensors trigger on sea breeze?

A: The directional sensors are calibrated to filter lateral wind movement. In the Barcelona installation, the hotel faces the Mediterranean and the false trigger rate is 5% even in Beaufort 4–5 winds.

Q: How long does fabrication and delivery take for a custom curved door?

A: Custom curved systems take 35–45 days from drawing confirmation to delivery. Installation itself takes 2–3 nights. We recommend allowing 50 days total from order to operational handover.

Q: Is there a maintenance contract available for European hotel properties?

A: Yes. We offer annual maintenance agreements with a guaranteed 48-hour on-site response for European properties. Please mention this when you contact us and we will include the terms in your quote.
