Implementing Sustainability Goals by the Numbers
Now that you’re on the path to becoming a truly sustainable printer, here are a few thoughts about how to reach that goal and some metrics that may help you tell when you’ve arrived.
Environmental Leader publishes a quarterly “Environmental & Energy Data Book” full of charts and graphs presenting environmental, sustainability and energy-related data. Download the PDF and use the information and metrics included to support your decision-making.
The following are some data points selected from the report; it includes dozens more.
First there’s the top 10 “100% purchasers” of green power. Ranging from Kohl’s Department Stores and Whole Foods Market to The World Bank Group and Dannon Co., These are the companies that are buying only green energy.
Mohawk Fine Papers is #8 on the list; last year it purchased 116 million kilowatt hours of power. That’s a big number! To give you a relative measure for comparison, using a 60-watt light bulb for one thousand hours consumes 60 kilowatt hours of electricity. (Thank you, Wikipedia.)
As you look at your energy use and begin to build a baseline on which improvement can be measured, it is helpful to know the areas where the most energy is used in general commercial buildings. Yes, an office building IS different from a print plant, but consider these general categories:
- Lighting and heating and cooling the physical space consumer more than half the energy in U.S. commercial buildings.
- Then you have water heating, electronics, refrigeration and computers.
Have you measured your energy use at this level?
Now that we know lighting is the top energy drain in commercial buildings—more than a quarter of all use—the next step is to evaluate your lighting systems. There are three criteria that are deemed “very important:”
- Energy consumption
- Lifetime operating/maintenance costs
- Suitability of lighting design for the task
Obviously, it is critical to do a complete lifetime ROI analysis before launching a full lighting retrofit, but finding new ways to bring in natural light and upgrading selective areas can reduce the overall cost. Picking the best “bang for the buck” will give you a good return your project without breaking the bank.
