# Seven Sustainability Projects: Project Implementation

This article reviews the 7th of the key elements for Low Cost – High Value energy savings. Each of the previous articles reviewed types of projects which are applicable at many facilities. The projects ranged from simple procedural actions such as turning off equipment when it is not making a product to more complex, like adding a water to air heat exchanger and extracting heat from the coolant loops to provide warmed make-up air.

## Seven Key Sustainability Projects

1. Metering 5. Lighting
2. Demand Control 6. Heat Recovery
3. HVAC Optimization 7. Project Implementation
4. Compressed Air

### Energy Projects Require Resources Too

Something that is important to remember is that even the simple projects require resources. Resources such as: time, labor, and opportunity. More complex projects require more: engineering, time, labor, opportunity, and capital funds. I often find that energy cost reduction projects are not treated in the same manner as for instance a project to install a new assembly line. When a plant is going to install a new line, formal project management steps often including a detailed tracking program like MS Project. When it comes to energy projects they often seem to be un-organized and the project management skills seem to be left out.

Here are the general steps that I use to analyze a plant with the goal to develop an Energy Cost Reduction Plan that will meet my goal of 10% reduction with projects and actions averaging less than a 1 year payback.

1. Determine the annual energy costs for electricity, gas, water, and sewer and use 10% of this cost for to set the target. (Example: annual costs total \$450,000 x 10% = \$45,000 savings target)
2. Perform assessments and collect measurements in the 6 key areas discussed in previous articles: Metrics, HVAC, Lighting, Compressed Air, Demand Control, and Heat Recovery.
3. From the measured data collected, perform analysis to determine the potential savings for each of the key areas.

### Summary

Treat energy cost reduction projects with the same level of importance as a construction project or new assembly line. Use the normal project management protocols. Take advantage of government and utility rebates. Make sure your projects have measurement and verification as part of the plan along with a validation small step before diving into a large project.
