Introduction

Hotels are complex facilities with many different energy consumers. A well-thought-out measurement concept is essential to monitor and optimize energy consumption. Using my experience from numerous energy audits in hotels, I would like to introduce you to a basic structure for such a measurement concept.

4

Battery storage

Used to store excess electricity from the PV system or CHP.

Key Points:

• Monitoring of charging and discharging cycles.

• Condition of the batteries and their lifespan.

7

Wellness and Sauna

Wellness areas with pools, saunas and steam rooms are energy intensive.

Key Points:

• Monitoring the energy consumption of heaters and pumps.

• Water quality and temperature.

10

Lighting

Monitoring energy consumption of indoor and outdoor lighting.

2

Combined heat and power plant (CHP)

The CHP (combined heat and power plant) is a central energy source in many hotels. It generates both electricity and heat and is therefore an important factor in overall energy consumption.

Key Points:

• Monitoring of electricity and heat generation.

• Recording of maintenance intervals and efficiency.

5

Wallcharger for Electric Vehicles (EVs)

With the rise of electromobility, it is important to provide charging infrastructure in hotels.

Key Points:

• Monitoring power consumption patterns.

• Number of charging processes and utilization.

8

Parking garages

Lighting, ventilation and security systems in parking garages consume energy.

Key Points:

• Monitoring lighting times and intensity.

• Ventilation systems and their efficiency.

11

Water Treatment

Hot Water Systems and Their Efficiency.

3

Photovoltaic system (PV system)

Solar panels can help hotels reduce their energy consumption and use green energy.

Key Points:

• Monitoring of electricity production.

• Checking the condition and efficiency of the panels.

6

Air Conditioning Systems

Air conditioning can account for a significant portion of a hotel's energy consumption.

Key Points:

• Monitoring energy consumption depending on the season.

• Efficiency and maintenance intervals.

9

Kitchen Operations

Air conditioning can account for a significant portion of a hotel's energy consumption.

Key Points:

• Monitoring energy consumption depending on the season.

• Efficiency and maintenance intervals.
