Abstract

Nowadays, people are demanding on their quality lifestyle. For a quality lifestyle, healthy, safe and comfortable indoor environments are needed. Therefore, this research investigates the environment condition within two types of buildings, natural ventilated and air-conditioned to gain better understanding of the indoor environment condition of the selected buildings. The main purpose of this study is to develop predictive model to forecast indoor environmental parameters by using Artificial Neural Network (ANN) technique. Hourly time-series data of three indicators including: air temperature, relative humidity and air velocity have been used to forecast the indoor environmental parameters. The data collected fiom the field measurements conducted at four traditional Malay houses have been used in training the network. Meanwhile, another two data sets fiom the field measurements conducted at a restaurant which applied'the concept of vernacular architecture and a library which was built with green building concept have been used to validate the model developed, The performance of the developed model is evaluated using R sqwed (R~a)n d was messed through a measure of Mean Square Error (MSE). The accuracy,. , .o: f the model is measured using the Mean Absolute Percentage Error (MAPE). The study has successfully developed ANN model to forecast indoor temperature, indoor humidity and indoor velocity. From the results, it was found that the best ANN to forecast indoor temperature is 3-37-1, 3-12-1, 3-30-1 and 3-17-1. As for the indoor humidity forecasting, the best ANN is 3-40-1, 3-1 1-1, 3-31-1 and 3-36-1. Lastly, the best ANN to forecast indoor velocity is 3-23-1, 3-30-1, 3-35-1 and 3-18-1. In conclusion, the evaluation performance of the model through the MAPE value shows that except for air velocity, the ANN model can forecast temperature and humidity within natural ventilated building. As for the airconditioned building, it is 'not accurate' due to the different building characteristics.
