Introduction
Hotel owners are constantly looking for ways to optimize costs. We update furniture, change suppliers, and review staff rates. But at the same time, we overlook one of the largest expense items that literally flies out of an open window — electricity for air conditioning.
Let's calculate the real figures using a medium-sized hotel as an example.
Typical Situation in a Hotel
Imagine a normal day at your hotel:
Recognize your hotel?
Real Experiment: Numbers That Speak for Themselves
We conducted a test in a hotel with 144 rooms occupied.
For a week, we recorded electricity consumption — first in normal mode, then with the IOTel automation system connected.
The result of implementing IOTel impressed even the technical experts:
- Electricity consumption decreased by more than 3,482 kWh per day.
These are not theoretical figures — this is a real result from an active hotel.
Let's Translate This Into Money
Let's convert kilowatts into money. We'll take an average electricity cost of 0.15 EUR/kWh (this may vary depending on your region and contract).
Hotel with 144 rooms:
30-room hotel: Annual savings — 39,172 EUR
200-room hotel: Annual savings — 261,150 EUR
Why Key Card Systems Don't Solve the Problem
Many hotels have already installed energy-saving card slots — that should help, right? In practice, this system has serious flaws:
1. Guests Cheat the System
- When issued 2+ cards, one is left in the slot.
- They use their own plastic cards (ID, loyalty cards, etc.).
- RFID cards can be bought online for pennies.
2. Inconvenience for Guests
- They have to find the slot in the dark.
- If there are multiple guests, they rely on one card for power.
- Constant complaints in reviews.
3. Open Windows = Running AC
- The system doesn't know about open doors/windows.
- The AC cools the street.
- Zero savings during ventilation.
4. Empty Rooms = Active Climate
- Staff forgets to remove the card.
- In the off-season, the system runs for nothing.
The Modern Solution: Smart Automation
The IOTel system works based on real sensors, not the presence of a card in a slot:
- Motion Sensors — determine the presence of people in the room.
- Door/Window Sensors — turn off the AC when opened.
- Controller — analyzes the situation and makes the right decision.
Result:
- ✓ Guests don't need to find or remember anything.
- ✓ The system works correctly regardless of the number of key cards.
- ✓ Protection against cooling the outdoors.
- ✓ Automatic shutdown in empty rooms.
- ✓ Bonus: Security system for off-season periods.
Quick ROI Calculation
Average cost of installing the system per room: 150 - 300 EUR
For a 30-room hotel:
What's Next?
Step 1: Calculate Your Real Losses
- How many rooms do you have?
- What is your average occupancy?
- How much do you pay per kWh?
Step 2: Order a Free Energy Audit
We will analyze your consumption and show the exact savings figures for your hotel.
Step 3: Test on Pilot Rooms
Install the system in 3-5 rooms and see the results for yourself.
Conclusions
Every day without automation is money thrown away. While you are reading this article, your air conditioners are running in empty rooms and cooling the street through open windows.
In just one season, you can pay off the entire system and start real savings. And the money that previously went to electricity can be invested in the development of the hotel.
