The result “Modular Real-Time Monitoring System Architecture customized for offline and online measurement, fed with data from cooling pavement and bioswale” features a system that integrates sensor data, cloud processing, and digital representations to continuously measure and analyse environmental and structural variables in the built environment. In MULTICLIMACT, the system is applied to assess the performance of cooling pavements and nature-based solutions by collecting, storing, and processing measurement data, supporting evidence-based evaluation and optimisation of these interventions.

The tool can be adapted to different sensors, data transmission protocols, data analytics, the communication of results or alerts, and graphical visualisations, enabling it to monitor different assets within the built environment.
In particular, within MULTICLIMACT, work has been carried out on the design of this adaptable and modular architecture, and its customisation, with different alternatives (determined by the specific circumstances of each real-world scenario, such as installation difficulty, existing coverage, site security against theft, availability or lack of power supply, etc.), for monitoring the new recycled asphalt pavements and bioswales solutions to mitigate the thermal and runoff effects associated with climate change.

The tool and its functionalities are shown in more detail in D3.2 and D9.2. In this case, it is applied to the measurement of relevant variables in M#2 Recycled urban pavements and M#7 Nature-Based Solutions, contributing to the analysis and improvement of these developments. It can also be applied to other built assets (e.g. as demonstrated here).

The parts of the system, as explained in the documentation mentioned above, are:

Main components of the modular real-time* monitoring system: (A) on-premises layer, (B) cloud layer, and (C) digital twin layer.
*near real-time capabilities depend on the power supply, communication network, and data transmission protocol selected according to site characteristics.

Functions that can be included in the system are: remote data collection, pre-processing and redirection via middleware, storage in a dynamic database, post-processing (including the option to deploy AI), and presentation in digital twin-type graphical environments.

At present, the information (data) and the tool are accessible only to selected participants within the context of specific tasks within the project (examples below). IoT sensors have been installed on the final prototypes of COMSA for pavements on Pirozzini Street and of NATURALEA for bioswales with infiltration capacity. Both cases are currently being prepared and studied, during which data and systems will be made available in accordance with the terms to be agreed upon during the course of that task.

The user group is broad and ranges from construction companies wishing to trial new solutions or monitor those they have already built, to public bodies needing to monitor the temperature or drainage performance of the city, as well as other infrastructure (the solution is designed to be applicable to all types of assets and the various variables that need to be measured). This system has been designed exclusively by TECNALIA, and plans are currently underway to register it.

The value of the result is offered by 1. flexibility to integrate different sensors to monitor the built environment, 2. providing real-time data, metrics and analytics, as well as 3. providing advanced digital contextualisation accessible remotely. Furthermore, IoT sensors are selected and integrated to measure the most trackable variables in M#2 Recycled urban pavements and M#7 Nature-Based Solutions, always prioritising the lowest cost and the feasibility and simplicity of implementation (for real-world urban construction environments without an electricity supply and with the capacity to cover a large area).

As explained, the result has been completed with the construction of the final prototypes, which will be evaluated using the system, as well as through supplementary on-site tests.
