PROJECT

Improve the energy efficiency of
a shopping centre

 

SECTOR

Chain of shopping centres

 

CLIENT

Shopping centre

         

SAVINGS

€32,000  a year

 

INVESTMENT

€21,000

 

PAYBACK PERIOD

8 months


Target achieved:

Optimising energy consumption in each centre and reducing the electricity bill


Results:

From the first month following the installation, there was already a 15% electrical energy consumption saving, and all the improvement measures resulted in an average saving per centre of €32,000 the first year. The payback period for the project was eight months. 

"The detection of inefficiencies caused by inappropriate consumption schedules, such as air-conditioning at night, enabled a saving of €8,000 a year through awareness, and the programming and/or remote control of those systems". 

Other savings were also confirmed, both in terms of use and maintenance, which facilitated a rational use of energy in the installations, including remotely via the WEB platform. Other improvements were achieved through the use of calendars to rationalise seasonal consumption

Waste water treatment plant (WWTP)

PROJECT

Improve the energy efficiency of a waste water treatment plant

 

SECTOR

Water treatment

 

CLIENT

Catalan Water Agency (ACA)

         

INFORMATION OF INTEREST

Efficiency improved after an 8.5% reduction in the (EnPI) kWh/m3 ratio of treated water

 

FALL IN ENERGY CONSUMPTION

69,745 kWh/year (-8.6%)

 

SAVINGS

€27,029 a year


Objective achieved:

Efficiency improved after an 8.5% reduction in the (EnPI) kWh/m3 ratio of treated water


Results:

With the implementation of a measuring, control and telemanagement system for Martorell's WWTP, the installation's electric energy management was improved, with energy ratio (EnPI) kWh/m3 savings of 8.6% and annual cost savings of €28,029, allowing payback on the investment in under 12 months.

The punctual control of the energy consumption of the electromechanical units and the detection of deviations in the specific electrical parameters measured (mainly current and voltage) enabled the adoption of a predictive maintenance program based on the early detection of breakdowns, which reduced the number of potential breakdowns and lengthened the useful life of units.


 Waste water treatment plant (WWTP)

Initial situation

The Catalan Water Agency, the water authority responsible for planning and executing the water policy of the Catalan government, has been implementing the Savings and Energy Efficiency Programme (PEEE in Spanish) in water treatment installations in Catalonia since the end of 2008.

As part of the actions of the PEEE, the Martorell Waste Water Treatment Plant (WWTP) in Barcelona, which is managed by the Catalan Water Agency through the operating company, Compañía General de Aguas de Cataluña S.A., implemented actions to improve energy efficiency via measurement units and an energy telemanagement system, to significantly reduce energy consumption in the installations and extend the useful life of the main electromechanical units. This action received financial support from the Catalan Energy Institute. 

Before the improvement, the total energy consumption of the Martorell WWTP and Anoia Pumping Station, in the year between September 2010 and August 2011, was 1,123,716 kWh.

Intelligent management system for street lighting

PROJECT

Efficient street lighting management

 

SECTOR

Street lighting / Municipalities

 

CLIENT

Municipality

         

INFORMATION OF INTEREST

Regulated lighting 50% of the time

 

ENERGY CONSUMED BY STREET LIGHTING

About 40% in most municipalities

 

ESTIMATED SAVINGS

Between 30 - 35%


Target achieved:

Control of the lighting, faster reaction time in the event of an incident and improved preventive maintenance


Results:

The client was able to lower its electricity bill for lighting by 30% to 35% with the installation of the CirLAMP intelligent lighting system.

Another one of the results obtained with the CIRCUTOR intelligent street lighting control system was that the client was able to reduce response times to incidents because it had real time information on the status of the installation.

The CIRCUTOR CirLAMP system provided additional benefits such as:

  • Faster response times to incidents: With fault identification, it is possible to know the status of alarms such as, for example, burnt out lights, lights in blinking mode and open capacitors.
  • Improved preventive maintenance that increases the useful life of the lights: The unit made it possible to report the operating time of each light, which in turn enabled changing them when they were reaching the end of their useful life. The system reported an event to the manager when reaching the programmed maximum operating time.

 Intelligent management system for street lighting

Initial situation

Street lighting, including maintenance, represented 40% of a municipality's total expenditures. This fact, together with the constant increase of electrical energy prices, made energy efficiency one of this entity's main objectives.

At the same time, the client was incurring constantly increasing maintenance costs due to the lighting, together with sporadic complaints of poor service from citizens.

Public administration buildings

PROJECT

Improve energy efficiency in a
public administration building

 

SECTOR

Public administration

 

CLIENT

Catalan Energy Institute (ICAEN)

         

SAVINGS

€34,552 a year (22.5% of the electricity bill)

 

INVESTMENT

€17,936

 

PAYBACK PERIOD

6.2 months


Objective achieved:

The integrated measurement and control system saved €34,552 on the electricity bill during the first year and ensured better energy monitoring and a more environmentally sustainable building.


Results:

As a result of applying all the measures taken, energy consumption was reduced by 20% in the period 2012-2013, with total savings on the annual electricity bill of 22.5% (€34,552) in 2013. 

As a result of the implementation of the management system and application of corrective measures the following results were achieved:

  • ––Inefficient consumption detected and corrective measures applied.
  • ––Savings in the measurements taken were recorded.
  • ––Payback on the investments made was calculated.
  • ––Evaluation and continuous improvement criteria applied.
  • ––Maintenance works controlled and improved.

 Public administration buildings

Initial situation

The Department of Business and Employment building is the headquarters for the Ministry of Energy, Mines and Industrial Safety, the Catalan Energy Institute (ICAEN) and the Catalan Consumer Agency. It had an annual energy consumption of 1,535,650 kWh, with an annual energy cost of €153,565, as well as a contracted power cost of €24,300 per year. The managers therefore prioritised improving the energy efficiency of the installations in order to reduce the average monthly energy consumption, which was 127,790 kWh.

The primary energy costs were air conditioning (36%) and lighting (25%). Consumption fluctuated given the normal working hours in the offices, although they were more variable than they should have been. There was no energy consumption forecasting or any comparison with previous months and years. According to the agreement of the Government of Catalonia, in their Energy Efficiency and Savings program of July 2007 and August 2011, to conduct energy audits in all Government buildings and premises with an annual consumption greater than 200,000 kWh, this building logically falls under said program.

More information about the solution:

The application comprised:

  • –A first screen of the single-line diagram type was used to check the real consumption and status of the system per line.
  • A second summary screen showed the calculation of performance, the preparation and display of reports with results for different periods (daily, weekly, monthly and annually )
  • In addition, the system allowed the definition of the minimum sizes of server groups, as well as the disconnection of unused capacity, always within the service levels.

Energy diagram. Data processing centre

Initial situation

The data centre has 100 kW of installed power with €80,000 in annual energy costs. Its managers prioritised the energy efficiency of the installations in order to reduce the monthly average energy consumption down to 72,000 kWh.

The main energy costs came from the computer and air conditioning systems. Consumption was constant, as the data centre ran on a 24/7 operation. There was no energy consumption forecast or comparison with similar data centres. They wanted to find out their Power Usage Effectiveness (PUE) value and compare it with that of other data centres, so they could determine their current level of efficiency, as well as the factors needing improvement in the installation.

Project

Pilot educational project for renewable energies in conjunction with the electrical network

  Client

Sheridan College Toronto (Canadá)

Background / objectives

Our conciliatory Renteknik, together with CIRCUTOR, has designed a proposal to merge other renewable energy sources with battery storage (two solar panels, a windmill and a water turbine) in the network to supply consumption at different installationss

General description

The system includes an EFM that controls and measures user consumption, the renewable generation value and the charge of the battery, giving priority in milliseconds to one source or another depending on its demand, all in real time. Also, the CDP0 analyzer prevents energy from being injected into the network in the case of excess generation and low energy consumption, as Canadian law prohibits it.

The powerful software PowerStudio Deluxe has been installed, integrating the units mentioned above, plus others, such as:

  • TR8 DC analyzers for solar panels
  • RGU-10 earth leakage protection relays with communication capacity, which are motorised, controllable and programmable remotely, sending a warning when triggered.
  • CVM-MINI electrical network analyzers and MC3 efficient current transformers
  • Weather station
Key features / Results

A future expansion is planned to add an electric vehicle charging station. This is a pilot project in a prestigious school, a reference for CIRCUTOR and renewable energies in Canada, which will have an impact on other similar schools and universities thanks to the innovative and high-profile nature of the project.
