Environmental burdens and human health impacts exist throughout the life of CBMs from non-renewable resources. This apprehension of the health impacts of CBMs can extend from indoor to outdoor quality. In this regard, there are several standard tests, such as the small chamber test (American Society for Testing and Materials (ASTM)-D5116), for evaluating the emission of indoor VOCs. Green Building Council of Leadership in Energy and Environmental Design (LEED) rating system are concentrated on VOC prevention. In terms of IAQ, most programs for evaluation materials such as the U.S. Ībove and beyond, CBMs are major contributors to indoor emission sources of volatile organic compounds (VOCs) that have the potential to deteriorate IAQ.

To address these issues, new materials and technologies are urgently needed in the construction industry. Reduction in different characters of building materials such as embodied energy, energy consumption, CO 2 emission, and recyclability can simultaneously affect both environmental and human health. For instance, toxic materials that affect indoor air quality (IAQ), produce toxicity pollution for the environment and human during the production stage. Quantifying these overall impacts on environmental and human health is complex and currently unaccounted. There is global concern and awareness about hazards from conventional building materials (CBMs) that have both social and environmental impact. The sustainable development (SD) perspective for construction materials is the effective manner of resources usage to meet the demands and preconditions of existing and future generations while reducing environmental degradation. The affluence of this urbanization makes this industry the most astonishing consumer of materials, most of them from non-renewable resources that need replenishing. This urban population has rapidly grown from 751 million (1950) to 4.2 billion (2018) in the world. The construction industry (CI) is one of the firmest emergent sectors in rapid urbanization due to the increasing population in urban areas. Our results indicate that the usage of biocomposite as GBMs can be an environmentally friendly solution for reducing the total indoor and outdoor impacts on human health. Life cycle assessment (LCA) methodology is used, and the results indicate that switching the fully hybrid bio-based biocomposite with the fully petroleum-based composite could reduce more than 50% impacts on human health in terms of indoor and outdoor.

Using a small chamber test (American Society for Testing and Materials (ASTM)-D5116) for VOC investigation and SimaPro software modeling with the ReCiPe method for evaluating human health impacts. This study aims to develop a model of fully hybrid bio-based biocomposite as non-structural GBMs and compare it with fully petroleum-based composite in terms of volatile organic compound (VOC) emissions and human health impacts. In this regard, biocomposites as GBMs are environmentally friendly, safe, and recyclable materials and their replacement of CBMs reduces environmental impacts and human health concerns. Given their sustainable development (SD) prospect, green building materials (GBMs) with non-toxic, natural, and organic compounds have the potential to reduce their overall impacts on environmental and human health. Conventional building materials (CBMs) made from non-renewable resources are the main source of indoor air contaminants, whose impact can extend from indoors to outdoors.
