However, due to the lack of awareness of irreparable noise damages, the potential of the auditory and non-auditory diseases is increasing. In the modular construction manufacturing, which is increasingly applied as a construction method, construction workers are substantially exposed to high-noise levels. In order to provide a healthier workplace, assessment of the noise exposure is necessary while in this industry has not been fully studied yet. Therefore, this paper presents noise exposure assessment of a modular construction factory. After investigating patterns of the tasks, task-based method (TBM) was applied as a measurement strategy. K-means clustering was used to determine the noise level of each task to calculate the noise exposure levels in different locations of the factory. The results of this paper can provide a useful guid...

In the early urban design stages, the optimization of the urban morphology and building physics characteristics can reduce energy demand. Local generation using renewable energy resources is also a viable option to reduce emissions and improve grid reliability. Notwithstanding, energy simulation and environmental impact assessment of urban building design strategies are usually not done until the execution planning stage. To address this research gap, a novel framework for designing energy systems for zero-carbon districts is developed. An urban building energy model is integrated with an urban energy system model in this framework. Dynamic prediction of heating and cooling demand and automatic sizing of different energy system configurations based on the calculated demands are the framework's primary capabilities. The wor...
