Healthy Buildings

How Indoor Spaces Drive Performance and Productivity A Fortune Magazine Best Book of the Year An AIA New York Book of the Year

A forensic investigator of “sick buildings” and director of Harvard’s Healthy Buildings program teams up with a CEO-turned–Harvard Business School professor to reveal the secrets of a healthy building — and unlock one of the greatest business opportunities of our time.

By the time you reach 80, you will have spent 72 years of your life indoors. Like it or not, humans have become an indoor species. This means that the people who design, build and maintain our buildings can have a major impact on our health.

A Fortune Magazine Best Book of the Year

This exposé of the widespread under-ventilation and pollution inside modern buildings arrived just as shared indoor space became truly deadly. Though there’s now light at the end of the COVID-19 tunnel, these insights and guidelines for improving indoor air quality should play a huge role in post-pandemic reforms.


An AIA New York Book of the Year

Laura Raskin

We’ve known for years that our indoor environments, from offices to hospitals, can have a dramatic effect on our health, functioning, and mental wellbeing, and 2020 has proven the point… [Allen and Macomber] share insider tips and show how tracking what they call ‘health performance indicators’ with smart technology can boost a company’s performance and create economic value. A post-COVID handbook.


The New Yorker

Jill Lepore

Allen and Macomber want to establish national standards, and they make a series of precise and persuasive recommendations for everything from insulation and window shades to water filters and vacuum cleaners.


Lord Norman Foster

Architect

This book should be essential reading for all who commission, design, manage, and use buildings — indeed anyone who is interested in a healthy environment.


Nature Scientific Journal

We shape our buildings and afterwards our buildings shape us,’ said Winston Churchill in 1943. This is even truer now; people in the United States spend 90% of their time indoors, note health scientist Joseph Allen and business-school lecturer John Macomber. Yet we read little about indoor air pollution. […] Their detailed, important study is welcomed by architect Norman Foster. But it speaks to everyone.


Cristina Gamboa

CEO of the World Green Building Council

Healthy Buildings makes a great contribution by urging us to shift to a ‘healthfirst’ mindset in relation to our built environment. Its unique insights help close the knowledge gap around healthy buildings, reveal their important role in global sustainability, and provide practical guidance on the main factors we should all be on the lookout for in our homes, offices, and schools.


John Mandyck

Urban Green Council

Sustainability and health can no longer exist in separate domains. Healthy Buildings bridges the divide. It links health science and business science for a new way to think about buildings.


Harold Wimmer

National President and CEO, American Lung Association

Indoor air quality directly impacts our lungs and we have a responsibility to remove indoor air pollutants that are linked to asthma, lung cancer, and other serious diseases. Healthy Buildings lays out the simple steps we can all take to improve our health.


Rebecca Henderson

John and Natty McArthur University Professor, Harvard University

Healthy Buildings is both hugely important and a great read. By the end it not only completely persuaded me that improving the health of our buildings is a fabulous economic opportunity and something that could change the lives of millions of people — it gave me a very good sense of where to start. Highly recommended.


Christoph Reinhart

Director of MIT’s Building Technology Program and Head of the Sustainable Design Lab

The engaging conversational style of this comprehensive book makes it an ideal read for any busy building owner or executive who wants to learn about the new science of healthy buildings and to discover how following healthy building strategies may impact their (and society’s) bottom line.


Thomas R. Burton, III

Chair, Energy and Sustainability Practice, Mintz

In this new era of ESG responsibility, every CEO must consider our built environment to fully meet stakeholder expectations. Joe Allen and John Macomber’s multi-disciplinary, accessible approach unlocks the secret to future human health and productivity gains in the very buildings in which we live and work.
