Monitoring Strategy

The main focus of the project is to develop integrated systems for the efficient retrofitting of non-residential buildings with a focus on public buildings. This means that each buildings needs to be monitored to assess the energy consumption, area of energy loss and how the building can reduce CO2 emissions………..

It is intended to carry out a systemic and systematic methodology approach on different Public Buildings and Districts with the intention of providing a standardized checklist of possible common constraints encountered whilst retrofitting public buildings and integrating proposed technologies.

The partner designated with the responsibility to determine the retrofitting strategy for each demonstration district is ACCIONA Infraestructuras . They have now completed a monitoring and evaluation plan to determine the best practice approach to retrofitting each of the demonstration districts.

monitoring-strategyAcciona has prepared a detailed measurement and monitoring plan of energy consumption and indoor environment for the selected demonstration buildings within the A2PBEER project with the aim to verify the final performance of the retrofitted demonstration buildings at each district.

The report collects the measuring strategy needed to determine the energy use in each demonstration district, based on a specific deployment of meters and sensors, and a distributed communication network.

Continuous monitoring of the building energy consumption, outdoor and indoor comfort conditions is to be carried out for 12 months before and post retrofitting. The aim is to demonstrate 50% energy consumption savings and significant CO2 reduction.


Extensive research by the A2PBEER team, has identified common aspects in the basic retrofitting requirements for Public Buildings. The identification of collective retrofitting approaches have been recorded as well as the assessment of suitable technologies, strategies for retrofitting and best practices on retrofitting.

As the development of the technologies are nearing completion, retrofitting is to begin at the demonstration sites. The next newsletter will show how this is achieved to best practice.

The monitoring intends to assess the electrical consumption (lighting and ventilation), heating consumption (space and DHW) and determine the indoor parameters (luminance levels, air quality, temperature and relative humidity) for the building but also determine the external conditions (temperature, wind velocity, solar radiation) within the climatic region.

This report will cover the following aspects:

  • Measurement strategy and process
  • Parameters to be measured and evaluated
  • Installation components to be used: meters, sensors and auxiliary equipment
  • Communication technology used
  • Installation topology and architecture
  • Transmission way and specific wiring diagrams
  • Commissioning and programming details
  • Measurement visualization specifications.

The devices selected to Measure and Monitor the buildings are listed below:

  • Surface brightness sensors placed on the ceiling.
  • Air Quality Sensors, Surface temperature and humidity with integrated probe.
  • Heating calorimeters with go and return temperature probes.
  • Direct measuring three-phase electricity meters
  • Weather Station (external brightness values, rain, temperature and wind speed).
  • Wind Direction Sensor
  • Solar Radiation Sensor
