How to Think about Energy Efficiency

I recently gave a talk to an engineering society about sustainability, with the emphasis on energy conservation and greenhouse gas emission reductions. I discussed “The 9 Purely Business Reasons to Reduce Energy” (see www.ccesworld.com/blog) to demonstrate the many purely common sense, financial reasons for companies to invest in energy efficiency. Gosh, give credit to us   …Continue Reading


New York City Ushers In Sub-Metering Rule

New York City’s Local Law 88 is now in effect. This rule contains requirements for buildings that are 50,000 square feet or greater to upgrade their lighting and to install sub-meters. A future article will discuss lighting, but this one will discuss sub-meters. New York City is one of the first cities in the nation to   …Continue Reading


Getting the Most from Your LED Lighting Replacement Project

  LEDs are all the rage now. LED vendors are beginning to advertise to a wide audience; they are being accepted. There have been great advances in LED lighting technology in recent years. Illumination no longer varies. LEDs can be dimmed or adjusted in other ways. LEDs can be made to resemble the fluorescents they   …Continue Reading


President Obama Submits Budget for Energy

How Will the Clean Power Plan Benefit Small Business?

This will likely go down as a banner year as the USEPA proposed, for the first time, national standards to limit emissions of greenhouse gases (GHGs) from existing power plants: the Clean Power Plan. However this turns out in terms of the legislative process in Washington, the federal government has certainly provided the signals that clean   …Continue Reading


Energy’s Changing Realities: Are You Taking Advantage?

The US Energy Information Administration (EIA) publishes nationwide and regional energy use data. While changes from year to year are not great, a longer view reveals a lot. From 2007 to 2013, total US energy use dropped 5%, while the GDP rose 6%. The US is becoming more energy efficient. Our mix of energy sources   …Continue Reading


Peak Demand Reductions Critical to Controlling Costs

Your operations – whether you manage one or several office buildings or industrial facilities – depend on electricity. You don’t have electricity, your company does not function. It’s as simple as that. Whether at home or at work, we are used to paying for electricity by how much we use (kilowatt-hours, kWh). Makes sense; you   …Continue Reading


Energy Practices And Results Watched By Outsiders

Buildings in NYC and elsewhere have undergone a “complete 360” when it comes to energy practices, costs, and usage. It used to be that buildings had no motivation to be more energy efficient; costs were just spread out to tenants who just accepted and paid the expenses as part of their rent or lease agreement.   …Continue Reading


Energy Efficiency: the Hidden Benefits

I was fortunate to have been the construction and environmental manager for the largest conversion from No. 6 oil to natural gas so far in NYC. Three large boilers, providing heat and domestic hot water for 8 high-rise apartment buildings and other areas, were upgraded in preparation for the fuel switch. It is now two   …Continue Reading


How to Sell Energy Projects Internally

As an energy, sustainability, and environmental consultant, I am constantly “pitching” projects to clients who can really benefit. Not benefit by saving the polar bear or the Amazon Rain Forest, but generating direct financial benefits. Not hypothetical or “blackboard,” but with real-life case studies. Convincing, overwhelming. I used to think this was a slam dunk   …Continue Reading
