Stairs
Stairs can play a significant role in promoting environmental health, building health and building biology. Stairs provide a means of accessing different levels within a building and can be designed to promote physical activity and reduce sedentary behavior. Stairs can also be designed to improve indoor air quality by allowing air to circulate between different levels of a building. By choosing stairs that are made from natural and renewable materials, are non-toxic and have a minimal impact on the environment, building owners can help promote a healthier indoor environment for building occupants.
