Fig. 2: Overview of all the different parameters that can be monitored, classified in 4 different levels.
The project aims to develop a monitoring kit for the analysis of the parameters shown in Fig. 2. The huge amount of generated data will be transformed into a single quantity: the IAQ index. This index will be able to describe the ‘global’ environmental risk for a mixed collection in a specific room. The index will not only be determined by environmental parameters but also by the sensitivity of the collection towards transformation. The real-time measurements can be processed with the IAQ monitoring software that calculates the IAQ index as a function of time. Besides the development of a monitoring kit and software to process data streams, the project will also develop a performance monitoring workflow as shown in Fig. 3.
Fig. 3: The workflow combines indoor air quality (IAQ) assessments with performance monitoring.
STEP 1: IDENTIFY RISKS & DEFINE RISK THRESHOLDS
An inspection of the mixed collection and the building is needed in order to determine the most critical rooms in the building and the most critical materials in a mixed collection. Once the materials in a mixed collection are identified, it becomes possible to determine threshold values for the transformation rates that may not be exceeded.
STEP 2: ANALYSE THE RISKS BY MONITORING THE ENVIRONMENT
Current technologies allow more and more to measure parameters from several levels continuously. This project will explore the possibilities of such continuous analyses by estimating how harmful the environmental conditions are from the measured transformation rates, by studying hidden relations shown in Fig. 1, and by calculating the IAQ-index as a function of time.
STEP 3: DATA PROCESSING AND INTERPRETATION
The user friendly software needs to store the data, it needs to visualize the data and it needs to process the data in order to detect patterns and alarm situations in the environmental conditions are. The processing will lead to the calculation of the IAQ-index as a function of time.
STEP 4: IMPROVE STORAGE CONDITIONS
During this project mitigation measures that can be realized in a short period of time will be performed in several rooms.
STEP 5: EVALUATE MITIGATION MEASURES
From the real-time sensors, the IAQ monitoring software is able to determine the IAQ index in a continuous mode. Therefore, collection caretakers can (1) develop control strategies for monitoring the indoor environment, (2) perform risk management, and (3) initiate a PDCA (plan – do – check – adjust) cycle to improve the IAQ. By performing a continuous IAQ assessment, the improvement of the IAQ index due to mitigation measures should be visible.
