Ask people how to reduce greenhouse gas emissions from buildings and most will say “improve energy efficiency.” That may be a step in the right direction, but it’s time to adopt a better measure – a building’s total carbon emissions.

Not everyone lives in a place or a situation that allows them to install their own solar panels. If you are among them, fear not! Here are four ways to source renewable power or at least compensate for the carbon emissions of the energy you use. These four methods make zero energy homes and buildings possible for everyone.

Although the price of solar panels has plunged in recent years, they are still the most expensive element of a zero energy home. It’s okay to defer installing panels until the time is right. Here’s how to plan your zero energy ready home so it’s ready for solar when you are.

This question is becoming more common as we begin to move past zero energy homes into the realm of positive energy. Homes can do more than power themselves. They can also put a huge dent in the energy use and carbon emissions from our personal transportation.

When you eliminate the cost of energy from your monthly budget, you also give your buying power a boost. With the right financing, energy efficiency is an investment that pays for itself. Here are several options for energy aware financing that will enhance the buying power of zero.

The U.S. Green Building Council (USGBC) announced an update to Leadership in Energy and Environmental Design (LEED), the most widely used green building program in the world. What’s new with LEED version 4.1? Net zero certifications for carbon, energy, water and waste. With these certifications and and its upgraded recertification program, LEED is truly a leader in encouraging climate-friendly green buildings.

For decades, buildings have been influenced by transportation trends. But the reverse is also true: transportation can be influenced through building location and design. It’s time for green building professionals to make both buildings and their associated transportation carbon-neutral.

Energy efficiency is at the core of all green building certification programs. It’s time to ratchet up these modest improvements to make homes as green as they can be by operating them entirely with clean energy.

The future is electric and the power will come mostly, if not entirely, from renewable sources. In Part Two of Energizing the Green New Deal, we get specific about strategies that utilities and heavy industry can utiliz e to address climate change and make a profit at the same time. Utilities will play a central role in guiding development of renewable resources and efficient ways to deploy them. Industry may present the greatest challenges, but there are existing technologies to smooth the transition, plus smart incentives and new technologies in the pipeline.

High performance homes are a great investment for the homebuyer, no matter how you measure it, as described in Part One of this series. But there are also many non-monetary benefits for the homeowner. These highly efficient homes are a win for everyone involved, including builders, realtors, lenders and utilities. Here’s a powerful list.

When addressing indoor air quality, let’s not leave out existing homes and buildings. The same principles that make new zero energy buildings more healthy can also be applied to existing homes, whether during minor upgrades or major renovations. The return is in improved health and comfort. This is the final installment of our three-part series on indoor air quality and health.
