As the world grapples with the challenge of reducing carbon emissions, energy efficiency has become the holy grail of sustainability. Governments, corporations, and building owners are all racing to install LED lights, add insulation, and upgrade to energy-efficient appliances. But what if I told you that this relentless pursuit of energy efficiency might actually be counterproductive? That in our zeal to save energy, we’re inadvertently creating buildings that are more, not less, wasteful?

It sounds counterintuitive, but bear with me. For decades, we’ve been focused on reducing energy consumption, and our tools for measuring energy efficiency have been based on a flawed assumption: that a lower energy bill is always a good thing. But what if the real problem isn’t the energy itself, but how we’re using it? What if the most energy-efficient buildings are also the most wasteful, because they’re designed to minimize energy use rather than optimize it?
Consider the case of the “net zero energy” building. These are buildings that produce as much energy as they consume, often through on-site solar panels or wind turbines. Sounds great, right? But what happens when the sun doesn’t shine or the wind doesn’t blow? These buildings become energy black holes, sucking in energy from the grid when they need it most. And what about the energy required to build and maintain these fancy systems? The carbon footprint of a net zero energy building can be just as high as a conventional one, if not higher.

Or take the example of “demand response” systems, which adjust energy usage in real-time to match supply. These systems can save energy, but they also create a culture of ” energy scrimping,” where buildings are optimized for minimum energy use rather than actual human needs. This can lead to uncomfortable temperatures, dim lighting, and even health problems for occupants.
The problem lies in our narrow definition of energy efficiency. We’re measuring success by minimizing energy consumption, rather than by maximizing the value we get from that energy. What if the most efficient building was one that used energy in a way that was both sustainable and comfortable? One that prioritized occupant well-being, productivity, and even delight?
So what’s the solution? It’s time to rethink our approach to energy efficiency and focus on “energy efficacy” instead. This means designing buildings that use energy in a way that’s both sustainable and beneficial to occupants. It means prioritizing natural light, comfortable temperatures, and healthy indoor air quality. It means using energy as a tool to create a better, more enjoyable experience for people, rather than just trying to save it.
This shift in thinking requires a fundamental change in how we design and operate buildings. It means embracing new technologies like building management systems, smart sensors, and advanced materials. It means engaging occupants in the design process and prioritizing their needs and desires. And it means recognizing that energy efficiency is just one aspect of a larger goal: creating buildings that are truly sustainable, not just energy-efficient.
So the next time you hear someone tout the benefits of energy efficiency, ask them: What’s the real goal here? Is it just to save energy, or is it to create a better world for all of us to live in?
