Instrument testing also allowed experiments of tuning and improving the efficiency and/or effectiveness of the boilers, chillers, AHUs and the lighting and electrical systems.

Analyzing the collected data is the transformative phase that turns raw information into actionable insights for green building sustainability. Techniques like descriptive statistics and machine learning not only unveil patterns but also unearth anomalies and opportunities. The emphasis on transparency and reproducibility ensures the reliability of findings, fostering accountability in decision-making. By framing the analysis to answer pertinent questions and test hypotheses, the process becomes a strategic tool for continuous improvement. Whether comparing building performances or optimizing indoor comfort settings, the analytical approach becomes a compass and a more sustainable future.

Raw data is messy. There may be isolated scenario in the operating pattern. the data transfer may be configured wrongly (i.e. the temeprature data is scaled to 0.5 times in the system, making the room appear to be colder than the actual temeprature). The sensing element may be faulty, resulting in further errors. Hence, proper cleansing of data is required to get the true picture of the situation. One must not only be a data scientist but also understand the know-how of the operation of the facility to explain the collected data. Only when the existing data can be reconciled and explained then can the facility be improved.

Garanta que os dados coletados sejam representativos e abranjam todas as variáveis relevantes para a sustentabilidade. Isso pode incluir dados relacionados ao consumo de energia, emissões de carbono, gestão de resíduos, eficiência hídrica, entre outros.
