Urban Heat Island Mitigation via roof gardens

2 rooms of a Chennai, Tamil Nadu, India-based facility were fitted with sensors at the terrace and room level. One room's terrace had a roof garden, and the other was exposed. The dataset presents the details of the temperature and humidity recorded at 4 places (garden indoor, garden outdoor, exposed indoor and exposed outdoor).

Two sets of industry-grade temperature and humidity sensors were installed for data collection. These sensors included cased sensors for outdoor measurements and exposed sensors for internal regions. One set of sensors was placed in the baseline monitoring zone, which was the area without a garden, while the second set was installed in the green/heat mitigation monitoring zone, which
was the area with the garden.
The precise locations of the four installed sensors were as follows:
1. The external baseline sensor was positioned in the southwest corner of the terrace in the exposed portion.
2. The internal baseline sensor was mounted on the restroom ceiling, below the external sensor in the southwest corner.
3. The external sensor for measuring data from the green roof was installed among the planter bags, near the parapet wall.
4. A corresponding internal sensor to measure the impact of the green terrace was mounted on the ceiling of the storeroom directly below the planter bags.
In addition to the sensors, secondary weather data for the larger Otteri neighbourhood was sourced from weather online, AccuWeather and Visual Crossing to complement the study.
