Immediate Value of Sustainability

We picture a world where people can live and work in healthy, thriving, productive spaces that are also good for the planet.

Buildings Deeply Affect People's Satisfaction

In the modern world, we spend 90% of our time indoors; buildings are people’s living and working environments and they deeply affect people’s satisfaction, health, and performance (1-4). It is essential that buildings have an optimal environment with the freshest air, enjoyable natural lighting and views, and balanced thermal comfort. These three features are important benefits of a green building because they have the largest positive impact on people’s lives as well as a company’s profits (1-6).

Green Initiatives can Boost Short-Term Corporate Profits

Over the last twenty years, companies have mostly approached environmental sustainability as a form of risk management in preparation for the future of energy as well as a source of positive PR and corporate reputation. Some companies that are sustainability leaders view going green as a core part of their business growth. These companies have mostly focused on reducing waste, in-house recycling, and reducing energy, as well as investing in R&D for new green products (7).

We would suggest that many of these common green practices are not the “low hanging fruit” for sustainability. As an example, installing solar panels on a business’s roof is a good investment but has limited immediate value. Solar panels today typically cost less per square meter than a glass window. In other words, glass windows are something people value more than a solar panel. While solar panels are unseen on a business’s roof, windows bring immediate value to a business. It is well understood today that an office with no windows and poor-quality fluorescent lighting will struggle retaining employees (1). And now there is a large body of research that shows that natural daylighting reduces employee sick days and provides a large boost in employee productivity at the office (1,4,5).

Effective Green Buildings Require Careful Guidance

Though natural light gives large benefits to corporations, covering buildings with floor-to-ceiling windows comes with durability issues and poor energy efficiency. And in a retrofit, it is difficult or expensive to knock down walls and add windows, which comes with more environmental sustainability problems. However, there are natural lighting solutions such as tubular skylights, which pipe daylight into offices, that can greatly reduce energy usage while boosting employee productivity. With these types of smart energy solutions, businesses can provide immediate improvements in employee productivity while protecting the environment and saving energy as value-added benefits.


Businesses should consider how a green initiative will boost corporate profits in the next five years and whether the payback period justifies upfront costs. We suggest that businesses incorporate green features that offer immediate benefits to their company by energizing their workforce.

From our research we’ve discovered three features of a green building that can provide immediate value as well as energy and environmental benefits: indoor air quality systems, daylighting and automated lighting systems, and building systems that improve thermal comfort. These value-added solutions for sustainability are the “low hanging fruit” that a smart and proactive business can pursue in the new emerging energy future.
