Sustainable Approach to Achieve New Green Solutions for the Construction Industry

In recent years, noise levels in administrative buildings have been considered one of the main causes of the stress and lack of productivity of employees. Based on the responses collected from a questionnaire survey distributed among companies with an open space configuration and studying the office’s acoustic conditions, from the specialized literature and through the authors’ experience, this study focused on the development of a new green dividing panel with superior sound absorption and acoustic insulation performances. In the experimental part, it was noticed that the presence of plants can influence the acoustic absorption values through their leaves’ conformation and distribution. Additionally, it was observed that the introduction of a coconut fiber layer in the panel led to higher values of the sound absorption coefficients in most of the studied plants. Through the conducted measurements, Tradescantia pallida registered superior values, with sound absorption coefficients with constantly increased values that varied in the range of 0.72–0.98 for the frequency range of 250–3150 Hz. Also, the weighted sound reduction index recorded a superior value of R w (C; C tr ) = 27 (−1; −4) dB, comparable to other existing solutions.
