Increasing and reinforcing positive energy use behavior is an effective and low-cost means to reduce energy consumption and the associated emissions, while also increasing internal awareness of our impacts on the environment. Our sustainability coordinator network regularly communicates opportunities to staff on energy savings opportunities at work and at home.
A primary method to reduce energy use is to eliminate unnecessary office space. With 90 + leases expiring in the next three years, we foresee significant opportunity to improve our energy efficiency and are actively incorporating energy use into our lease negotiations.
Due to office lease agreements, we do not directly pay for utilities for approximately half of our offices. Therefore, our total annual office energy consumption is calculated using a hybrid method which combines actual energy usage and estimates based on office square footage and a national office consumption metric. Where provided, we use actual utility data from our offices, which includes electricity and heating / cooling energy use as energy types. For the remaining offices, we used a national office energy consumption metric from the US Department of Energy’ s( DOE’ s) Commercial Building Energy Consumption Survey( CBECS).
Since FY14, we have been able to gather more actual utility data through engagement with our property managers. Better data has been used to update our estimation methodology and generate a more accurate figure for our total office energy footprint.
We revised our FY14 baseline to reflect this change. We estimate our total office energy consumption each fiscal year, and use full-time equivalent employees( FTE’ s) as a normalizing factor to measure our progress. Since FY14, we estimate a total office energy reduction of 3 percent( 1,525 Gigajoules), or 10 percent reduction when normalized to FTE’ s.
