Energy efficiency solutions for
non-residential buildings

Capacitor banks increase the efficiency of installations and network analysers can measure energy consumption and quality.

* The energy savings are given for information purposes only. These calculations are the results of mathematical simulations or measurements on actual cases.

 

01. Transformers

Zucchini low loss dry-type transformers optimise consumption when buildings are not being used.

Savings for a data center comprising two 250 m 2 areas
- € 540 a year
- 816 kg CO 2 a year
- Payback period less than 5 years

04. Measuring devices

These are used to monitor the electrical parameters of the installation, and to detect and anticipate problems, as well as to optimise the electricity supply and improve the performance of the electrical distribution.

Savings for a 300 m 2 office complex
- € 799 a year
- 1,000 kg CO 2 a year
- Payback period less than 16 months

02. Network analysers

These are used to monitor the electrical parameters of the installation, and to detect and anticipate problems, as well as to optimise the electricity supply and improve the performance of the electrical distribution.

Energy quality improving energy performance.

03. Capacitor banks

These cut out billing of reactive energy, optimise standing charges and improve the efficiency of the installation (for the same standing charges)

Savings for a 1,000 m 2 supermarket
- € 1,128 a year
- 1.6 T CO 2 a year
- Payback period less than 2 years

 

05. Solutions for data centers

The Varicondition Cold Corridor® solution, is a system which is based on the complete separation of hot and cold air flows, to increase efficiency and energy savings.

06. UPS (Uninterruptible Power Supply)

An intelligent power factor correction circuit optimizes the absorption of energy input. Efficiency remains at a consistently high level even at low capacity.

 

Legrand Zucchini HV-LV transformers

Plan of house

Zucchini low loss dry-type transformers:

  • - Optimise building consumption during standby phases
  • - Reduce hazards such as the risk of propagation of fire and spreading pollutants into the environment
  • - Make the end-of-life recycling stages easier
  • - Avoid heavy maintenance work

Payback period 5 years maximum(1)

Greenhouse gas (ghg) emissions avoided
816 kg eq. CO 2

CO 2 equivalent of all polluting gases (CO 2 , methane, carbon monoxide, fluorinated gases, etc.)
(1) Prices and data not contractual

 
 

These are made of recyclable materials and do not have to be integrated in a special insulated structure as they are small and their noise is limited.
Their efficiency differs according to the technology, the periods for which they are used and their loading ranges.
