# Data on air temperature, relative humidity, and dew point in three housing modes in a building in a hot and humid area of Douala, Cameroon

## TL;DR

This study presents detailed data on temperature, humidity, and dew point in different room types of a building in a hot and humid area of Cameroon over a year.

## Contribution

The study provides high-resolution, long-term microclimatic data for three distinct housing modes in a tropical climate.

## Key findings

- Data was collected for 365 days at one-minute intervals, totaling 525,600 records per parameter.
- The dataset can be used to model building thermal performance and improve architectural design in tropical regions.

## Abstract

The purpose of this article is to present the spatiotemporal dynamics of temperature, relative humidity and dew point in a residential building according to three dwelling modes in Douala, Cameroon. These microclimatic parameters were collected outside and inside three rooms, namely an open and unoccupied room (S1), a closed and unoccupied room (S2) and an occupied room (S3). Data collection were carried out over 365 days at one-minute intervals, resulting in a total of 525,600 records for each parameter. The data were collected using EXTECHⓇ RHT10 thermohygrometers. It was then transferred and processed in Excel and imported into MATLAB software to represent seasonal variations. The data collected can be used in simulation software to model the thermal performance of buildings in tropical areas. They can also be used to help design walls, roofs and windows to minimise overheating during the dry season and heat loss in the cold season.
