Here at Carbon Lighthouse, we’ve never been afraid to think big — the breadth of our ambition is matched only…
Our approach, which we call ‘Efficiency Production,’ is a long-term commitment. That means we don’t just drop in, offer advice and move along. We know that energy savings only persist when someone takes ownership for them. If energy savings aren’t measuring up, we cut a check to our clients. No matter how smart your projections, there’s always going to be efficiency drift over time.
Success in today’s hospitality industry is a boundless boxing fight (bear with me on this metaphor) to maximize revenue per available room (RevPAR) and over-index on the STR Report. When I was in the hotel business, I was so focused on improving customer experience to push rates that I never gave much thought to electric bills.
Today, Carbon Lighthouse is proud to announce that we have been named in the prestigious 2018 Global Cleantech 100, produced…

Your tenants will tell you some of what you need to responsibly manage your building: it’s too hot, it’s too cold. But there are so many more energy savings hidden in your building, from not putting air pumps into overdrive to coolant at the right temperature, that we’ve given them a name: Efficiency Reserves.
At nearly 150 years old, Alexander & Baldwin Inc. (A&B Inc.) knows something about longevity. The largest owner of grocery/drug-anchored retail centers in Hawaii was founded as one of the first ever corporations in the state. What started as a small sugar cane growing enterprise quickly expanded into an agricultural, shipping and real estate powerhouse.
In their first year in the energy efficiency business, Carbon Lighthouse founders Brenden Millstein and Raphael Rosen encountered a client who almost stole their thunder. When Millstein and Rosen first visited the building, an office building owned by Dostart Development, they saw that the owner had already changed out incandescent lightbulbs for LEDs and upgraded their HVAC system.
There are two fundamental concepts related to how much energy cooling systems must use: sensible heat and latent heat. So which type of heat, sensible or latent, requires more energy to remove?
Electricity costs for most commercial buildings are based both on the maximum power and the total amount of energy you use. Power and energy are different concepts, with very different costs, yet financiers, journalists, and pretty much everyone struggles to differentiate them.
There is another way to achieve carbon neutrality that is little know about in business circles but well regarded in the energy and environmental community. They care called carbon allowances. Like Renewable Energy Certificates, carbon allowances have as a strong suit that they are verifiable. They are also limited in number, and cleared through the government and therefore much less susceptible to fraud.
Using the principles of thermodynamics, we can keep people comfortable in a building while using energy in smarter ways. Thermodynamics teaches us numerous tradeoffs and rules that allow us to get the right temperature in the right place at the right time for the least amount of energy.
The difference between efficiency and efficacy is representative of the many issues that get ignored when discussing lighting and energy. But failing to understand this difference or the other nuances of lighting and energy, can turn what looks like great energy savings in theory into a poor investment.
From our experience working in buildings, it’s not surprising why measures may not perform as expected. It takes rigorous management to maintain performance.
It can be hard to discern what is actually best for managing energy usage in your particular building, especially because all tools come with real costs and limitations. Products should match the complexity of the building you run and the resources you have.
