Commercial and industrial

Large tertiary buildings face various issues and challenges due to climate concerns. Energy efficiency is a major priority for them, as these buildings typically consume a significant amount of energy for heating and cooling. Reducing energy consumption and optimizing HVAC systems contribute to lowering the carbon footprint of these buildings.

Who is affected ?

All branches of the tertiary sector are affected:

• Offices
• Public services
• Education
• Healthcare and social services
• Justice
• Retail
• Hospitality
• Restaurants
• Tourism and leisure residences
• Sports facilities
• Cultural and entertainment facilities
• Warehouses
• Airports
• Railway, road, maritime, or river stations
• Data centers and operation centers
• Parking facilities
• Laundries
• Printing and reprography, etc.

All existing and new constructions

with a floor area for tertiary activities (or a cumulative area) equal to or greater than 1,000 square meters are subject to this regulation.

There are a few rare exceptions

for temporary constructions (precarious building permits), places of worship, and activities for operational purposes related to defense, civil security, or domestic security.

This regulation applies to nearly 68% of the affected tertiary sector.

What is the water loop?

The principle of the water loop is that of transferring energy between different areas of a building, neighborhood, or district.

The water loop transfers heat or cold from one place to another, and the UtCi units harness this energy using thermodynamic processes to provide heating or cooling to various living spaces as needed.

At the scale of a living environment, here is how it can be represented:

The water loop operates ideally at temperatures between 20 and 31 degrees Celsius.

It can function independently if the needs are balanced, or it can receive external inputs (such as from an Intuis heat pump) to maintain a certain temperature :

The water loop system offered by Intuis:

• Provides heating, cooling, air renewal, and thermal recovery.
• Delivers 4 to 7 times the amount of energy it consumes.
• Utilizes free inputs (data centers, solar-exposed facades, etc.).
• Harnesses and recycles lost energy into the loop (waste heat).
• Reduces primary energy consumption and CO2 impact.

Its performance allows for obtaining various certifications such as HQE, BREEAM, LEED.

Even though the initial investment may be higher, it is currently one of the best ways to generate savings and lead your building into a virtuous circle.

While water loops are often proposed for purely commercial buildings, their use in mixed-use zones (combining offices and residences) also allows for the recovery of heat to provide hot water to residential areas from the same initial energy source.
