Editorial: Energy savings evaluation criteria and preliminary results

The Energy Saving Methodology adopted in EDISON was developed paying attention to accuracy and practicality aspects, and taking into account the framework of the so called "International Performance Measurement and Verification Protocol" (IPMVP) Measurement and Verification (M&V) Guideline, applied to lighting retrofitting actions. The aim of the IPMVP is to assess the energy saving resulting from the EDISON solution implementation, in particular by highlighting the energy saving due to ICT components (daylight and presence sensors). The Key Performance Indicators (KPI's) identified at the beginning of the EDISON project will allow a direct comparison of EDISON results, collected in different typologies of building and countries. The EDISON methodology for assessing energy saving has been designed in order to:

  • reduce uncertainties to reasonable levels;
  • monitor equipment performance;
  • evidentiate potential extra savings;
  • improve the behavioral end user habits;
  • verify that the planned cost savings are met;
  • confirm that the equipment/systems installed have the potential to generate predicted savings;
  • verify that the installed equipment/systems continue to have the capacity to yield the predicted savings over time.
In every Energy Efficiency Programme, a Measurement and Verification Plan is required to determine the savings achieved by the implementation of energy saving solution. Energy Saving COs (ESCO's) in the European Association of ESCOs have adopted the above mentioned Protocol (IPMVP) as their preferred guideline to write the M&V Plan within the Energy Performance Contracts. IPMVP is not only the most known M&V protocol around the world, but it is also the most prestigious within the international technical community.

When Public Building Managers (PBM) invest in energy efficiency they want to know how much they have saved and how long their savings will last. The determination of energy savings requires both accurate measurement and replicable methodology (the above mentioned M&V protocol).

The IPMVP defines general procedures to achieve reliable and cost­effective determination of savings. The long­term success of energy management projects is often hampered by the inability of project partners to agree on an accurate, successful M&V Plan. EDISON goal has been as much compliant as possible with a M&V Protocol providing procedures that, when implemented, help buyers, sellers and financiers of energy projects to agree on an M&V Plan and quantify savings from Energy Conservation Measure (ECM).

In case of Energy Performance Contract (EPC) as proposal for future EDISON implementations, the M&V Plan, which has to be reviewed and accepted by the customer prior to project implementation, will become part of the contract's terms and will define the measurements and computations to determine payments or demonstrate compliance with a guaranteed level of performance.

EDISON technical partners considered M&V Option A as the most suitable methodology for assessing the energy saving.

Option A is intended for retrofits where key performance factors (e.g., end­use capacity, demand, power) or operational factors (e.g., lighting operational hours, cooling ton­hours) can be spot­or short­term­measured during the baseline and post­installation periods. Any factor not measured is estimated based on assumptions, analysis of historical data, or manufacturer's data. Thus, the savings from a lighting system retrofit can typically be more accurately estimated with Option A than the savings from a more complicated chiller retrofit.

A key consideration in implementing Option A is identifying the parameters that will be measured and those that will be estimated. The key performance indicator that the ESCO is responsible for should be measured in both the baseline and performance period cases, and savings should be calculated from these values.

For EDISON, energy consumption, burning hours of significant periods (energy saving of the ICT components) will be collected by the implemented smart metering system.

Moreover in Option A the estimated parameters will affect the reported savings over the entire reference period. All estimates should be based on reliable, documentable sources and should be known with a high degree of confidence. The EDISON metering architecture will ensure the reliability of the estimates in term of system burning hours.

M&V Option A suggests to verify the savings through spot/short∼term metering and inspections conducted immediately before and immediately after installation. For EDISON monthly inspections will be conducted to verify that the equipment/systems are working properly and performing to specification.

During the last period all technical partners coordinated by Enel Sole have worked in implementing the methodology. Some preliminary evaluations have been studied and confirm that target energy saving values of EDISON have been reached. In VUB restaurant pilot, EDISON ensures an average energy saving of 65% of which 15% referred to ICT implementation with 5 tons of CO2 avoided per year. Roccamontepiano and Lettomanoppello schools show similar energy saving values between 56% and 64% with ICT components that provide an additional 9% of savings. Final assessed evaluation will be presented in the final report of EDISON project.

 
Focus on a Pilot Action: Abruzzo's Pilots

In the municipality of Lettomanoppello, a small town in the province of Pescara, Italy located in a hill, 370 meters above sea level, on the edge of the Maiella National Park, are currently running two pilots of the EDISON project. The buildings involved are the Municipality and the Primary school.

Municipality of Lettomanoppello

The Municipality of Lettomanoppello is located in an old fashioned building, built at the end of 19th century in the center of the town. The indoor area includes four floors with 41 rooms and a total area of 860 square meters. The internal rooms are addressed to different activities such as store room, stairwell, restroom, corridor and administration office.
The Pilots includes around 200 lighting points that are mainly 120cm neon tubes and light bulbs.
According to the EDSON solution the lighting points have substituted with equivalent LED lamps that are managed through Remote Stations (RS) and two different types of Central Power Control (CPC) devices: CPC-Master and CPC-Slave.
The number of installed CPCs and RSs are reported in the following table:










Offices are open 8 hours per day and around 25 days per month. People working and visiting the building are around 100 per day.

Some internal views of the Pilot lighting infrastructure.

In the pilot have been installed 30 presence sensors linked to the RSs and 9 lighting sensors each one linked to every CPC slave.
The pilot started running since February 2013 and currently have collected more than 10 months of energy consumtion data. From a first analysis of these data results an energy saving of about 70% of which around 10% due to ICT components and 8% due to the use of a centralised DC power.

Primary school of Lettomanoppello

The building hosting the primary school of Lettomanoppello has two floors and around 50 rooms addressed to different activities such as classroom, bathroom, corridor, lumber room, atrium, etc.
The total surface area that has been involved in the EDISON Pilot is about 1500 sqm wide and is open to the students, teachers, administratives and cleaning staff for 9 hours per day and 6 days per week. The total people attending the facility each day is approximately 250.
The EDISON infrastructure has been completed during the month of February 2013 and the next month started the running period during which energy consumption data was collected.
According to the EDSON solution the lighting points have substituted with equivalent LED lamps that are managed through Remote Stations (RS) and two different types of Central Power Control (CPC) devices: CPC-Master and CPC-Slave.

The number of installed CPCs and RSs are reported in the following table:


In addition was installed 32 presence sensors linked to the RSs and 10 lighting sensors each one linked to every CPC slave. Up to now have been collected more than 8 months of energy consumtion data. From a first analysis of these data, an energy saving of about 70% was observed. Of this, around 10% is due to ICT components and 8% is due to the use of a centralised DC power.

Dissemination & Exploitation actions

During the last months of the project lifetime the exploitation activities have progressed with the involvement of the Consac company as new Pilot through which promoting the advantages derived from the adoption of the EDISON solution in public buildings. Consac, in fact, is a voluntary consortium among Municipalities in the area of Cilento (Italy) with the mission of managing the local integrated water services, and for this reason it might represent a good opportunity for boosting the EDISON idea in this territory and in the surrounding areas.

With this goal, in the occasion of the Workshop "Energy Saving and Energy Efficiency", promoted by Consac on December 11th, 2013 at Vallo della Lucania (Salerno, Italy), the EDISON project has been presented focusing on the possible synergy between EDISON ICT solutions and the use of "water smart grid" through which optimizing control and monitoring processes aimed at increasing the efficiency of water networks in terms of quantity and quality of the water, as well as energy consumptions in the distribution network.
As a result of this dissemination event, Consac joined to the project with the request of implementing an application of the EDISON platform in one of its sites.

In addition, the Pilot action to be implemented in Zeist (The Netherland), which had been already mentioned in the previous issue of the project newsletter, has been successfully realized in the last November 2013, and is currently running.
The building involved is a Mosque which extends on an area of about 100sqm, with a lighting distribution network including 64 LED tubes. These two exploitation initiatives, together with other launched or in progress, contribute to guarantee the widest possible diffusion of the project idea, which is recently taking advantage of the contribution provided by the availability of social tools like Facebook and Twitter.

Next events

3rd EDISON Workshop which will be held in Belfast (UK) in May 2014. The event will be organized with the goal to present to the main stakeholders the energy savings results gathered in almost all the Pilots implemented.

 
Project News

The 2nd EDISON Workshop took place on the 15th October 2013 in Perugia (Italy). It was jointly organized by FUB and Ancitel in the ANCI (Italian Municipalities National Association) Headquarters in order to disseminate the most updated EDISON solutions operating in the Pilots sites currently running. Particular focus has been devoted to the criteria adopted to evaluate energy efficiency preliminary results achieved in each Pilot action, putting them into comparison with the ones proposed by other ICT PSP EU initiatives like the VERY School project, which has been hosted by the event.

The Workshop concluded with synthesis on how the EDISON project could address some of the existing issues under the topics of reducing energy losses and consumption in conjunction with the corresponding CO2 emissions in public buildings, gaining the consensus of the local Authority represented by the Environment Councilor of the Perugia Municipality Dr. Lorena Pesaresi, who has welcomed the participants.

- All the Pilot actions planned in the project have been completed and activated, and the corresponding measurement and validation phase of the collected data is currently ongoing.
Big efforts have been produced by all the partners Consortium in order to replace as soon as possible the Pilot action in the Museum building of IDIS-Città della Scienza in Naples, which has been completely destroyed by the tragic fire event of the last March 4th 2013 www.corriere.it/english/13_marzo_05/citta-della-scienza_f1827b5e-8589-11e2-b184-b7baa60c47c5.shtml.
Thanks to this additional work, the number of the Pilot actions has been not changed with respect to what defined in the project proposal, with evident advantages for the amount of data which may be collected and analyzed.

 
Agreement Anci Campania/Anea for Energy Efficiency

A Memorandum of Understanding Anci Campania and Anea, Neapolitan Agency for energy and environment, has been signed on February 28. The aim of the protocol, the energy savings in Campania: reduction of CO2 emissions resulting in increased energy savings, which translates into savings in the budget. The ANCI and ANEA are committed to create a network of municipalities, with the aim to promote, encourage and plan the implementation of energy efficiency measures and renewable power plants in the region. Municipalities in fact, are the main players for the dissemination of energy efficiency and the proper installation of renewable energy systems, local authorities therefore need support for the realization of innovative projects in the energy- environment. The agreement provides, among other things, support to governments in the preparation of projects Paes (Sustainable Energy Action Plans) for the towns of Campania who wish to engage in the reduction of CO2 emissions. For institutions that join the project will also be available a regularly updated database, where they will announce all the funding opportunities active at the time of the consultation, as well as a system of alerts for each update

We are very pleased to find in a partner Enel willing to share with us projects that aim to improve services for the citizens of Rome".

 
9 municipalities of Turin rewarded for energy improvement

There are nine municipalities of the province of Turin rewarded for their energy upgrading of public buildings. The administrations of Avigliana, Bruino, Bussoleno, Buttigliera Alta, Frossasco, Giaveno, St. Ambrose, Villafranca and Vistrorio, won the Award for Sustainable Energy in 2013, established by the Province of Turin in the project ' Regional Energy Concepts 'co-funded by the European program 'Central Europe'. The Prize for Sustainable Energy is the way in which the Province of Turin has joined this year 'M'illumino less', an initiative to raise awareness about energy savings created by the transmission of Rai Radio 2 Caterpillar'. The interventions should be rewarded by the installation of solar thermal and photovoltaic restoration of roofs, from the replacement of boilers, windows and doors to the insulation of attics , the insulation of the perimeter walls to coat the inclusion of thermostatic valves and heat reflective panels, from the replacement of old lighting systems to the introduction of remote control systems of thermal plants "This award is proof plastic - said the provincial environment commissioner, Roberto Ronco - of how an entire territorial system was able to achieve in practice, in a coordinated action, a set of projects on the front of the retrofit. A test of good local governance that we leave a legacy to those who come after the Province."
