By 2050, 70 percent of the world population will live in cities, a change that will add 40 percent to the current world building stock.
Because buildings can be big polluters, urbanization is also a stark reminder that economies everywhere benefit from investments in energy-efficient structures and by retrofitting inefficient, existing buildings. There’s some good news to report in that area.
For the first time since the 1973 oil embargo and subsequent energy crisis added “energy efficiency” to our everyday vocabulary, three trends are finally moving the world’s largest economy in the right direction. Financial incentives are driving this fundamental shift.
1) Households save money – by saving electricity
Americans today seem to understand just how important efficiency is in their daily lives. A recent study shows that homeowners now value ENERGY STAR-rated appliances – which have an efficiency stamp of approval from the U.S. Department of Energy – over luxuries such as a pool or a state-of-the-art sound system.
And adults aren’t the only ones getting in on the action.
Girl Scouts and their families participated in a recent youth-energy program that inspired home energy conservation measures, with up to 5 percent in electricity savings and 3 percent in gas savings as a result. In this case, educating kids helped their families save electricity.
2) Commercial buildings of all sizes go for retrofits
A number of recently released studies indicate that commercial buildings in the U.S. are becoming more efficient with energy use per square foot dropping 12 percent between 2003 and 2012.
Growing investments in energy efficiency – through technologies such as LED lighting, heating and air conditioning upgrades, and Building Automation Systems – are driven by passionate building managers who are promoting the twin concepts of financial and social value.
Where once only larger properties tended to invest in efficiency, the small and medium-size commercial building market is now poised to grow by more than 60 percent to $38 billion by 2025.
Smaller buildings have historically had less staff and access to funding for such projects. But now, due to a widespread emphasis on energy management and its ability to improve bottom lines, these smaller buildings are also beginning to explore simple energy efficiency upgrades and more complex retrofitting opportunities.
3) Partnerships in states push for energy savings
A number of states – including Illinois, New York and California – are working on legislation that help communities save energy. While the states’ goals vary, it’s telling that politicians, environmental groups, business leaders, and consumer advocates work together constructively to put in place energy efficiency standards.
Such efforts simply make good financial sense.
A key example of policy already generating financial and efficiency gains is a 2011 Illinois law that mandated the modernization of the state’s electric grid. It’s led to unprecedented collaboration between utilities, consumers and environmental groups.
So far, this legislation has produced groundbreaking metricsto measure the clean air benefits of smart-grid investments, as well as energy savings for commercial real estate and improved grid resiliency.
There are only wins here. While saving millions in annual energy expenses for households and businesses, improving efficiency can help cut global carbon dioxide emissions from buildings by an estimated 83 percent.
It just takes economics to get us there.
