Concept
Healthy building
Summary
Healthy building refers to an emerging area of interest that supports the physical, psychological, and social health and well-being of people in buildings and the built environment. Buildings can be key promoters of health and well-being since most people spend a majority of their time indoors. According to the National Human Activity Pattern Survey, Americans spend "an average of 87% of their time in enclosed buildings and about 6% of their time in enclosed vehicles."
Healthy building can be seen as the next generation of green building that not only includes environmentally responsible and resource-efficient building concepts, but also integrates human well-being and performance. These benefits can include "reducing absenteeism and presenteeism, lowering health care costs, and improving individual and organizational performance." In 2017, Joseph G. Allen and Ari Bernstein of the Harvard T.H. Chan School of Public Health published The 9 Foundations of a Healthy Building: ventilation, air quality, thermal health, moisture, dusts and pests, safety and security, water quality, noise, and lighting and views.
Healthy building involves many different concepts, fields of interest, and disciplines. 9 Foundations describes healthy building as an approach built on building science, health science, and building science. An integrated design team can consist of stakeholders and specialists such as facility managers, architects, building engineers, health and wellness experts, and public health partners. Conducting charrettes with an integrated design team can foster collaboration and help the team develop goals, plans, and solutions.
There are many different components that can support health and well-being in buildings.
Spengler considers indoor air quality as an important determinant of healthy design. Buildings with poor indoor air quality can contribute to chronic lung diseases such as asthma, asbestosis and lung cancer. Chemical emissions can be outgassed by building materials, furnishings, and supplies.

ASHRAE
The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE ˈæʃreɪ ) is an American professional association seeking to advance heating, ventilation, air conditioning and refrigeration (HVAC&R) systems design and construction. ASHRAE has over 50,000 members in more than 130 countries worldwide. ASHRAE's members are composed of building services engineers, architects, mechanical contractors, building owners, equipment manufacturers' employees, and others concerned with the design and construction of HVAC&R systems in buildings.
Passive ventilation
Passive ventilation is the process of supplying air to and removing air from an indoor space without using mechanical systems. It refers to the flow of external air to an indoor space as a result of pressure differences arising from natural forces. There are two types of natural ventilation occurring in buildings: wind driven ventilation and buoyancy-driven ventilation. Wind driven ventilation arises from the different pressures created by wind around a building or structure, and openings being formed on the perimeter which then permit flow through the building.
Built environment
The term built environment refers to human-made conditions and is often used in architecture, landscape architecture, urban planning, public health, sociology, and anthropology, among others. These curated spaces provide the setting for human activity and were created to fulfill human desires and needs. The term can refer to a plethora of components including the traditionally associated buildings, cities, public infrastructure, transportation, open space, as well as more conceptual components like farmlands, dammed rivers, wildlife management, and even domesticated animals.
