Sustainability Projects

KPPC has helped more than 800 businesses and organizations in the state discover sustainable opportunities, improve their environmental performance and lower operating costs. And the list of companies KPPC has guided along the way continues to grow – as do the advantages of improved sustainability.

Water Conservation

As part of an energy reduction effort, a Canadian technical college hired a compressed air auditor to do a leakage audit of their large campus, which houses over 30 mixed use buildings, including laboratories, research facilities, shops and classrooms. The audit found very few leaks, the reduction of which would achieve minimal savings; however, a few surprising items of interest were noticed during the study that showed very good potential for operating cost savings of 64% with an estimated $45,000 per year in reduced energy and water costs. This article discusses some of the findings and how savings can be achieved on lightly loaded compressed air systems.

Steam

Properly functioning steam traps open to release condensate and automatically close when steam is present.  Failed traps waste fuel, reduce efficiency, increase production costs and compromise the overall integrity of the steam and condensate systems.  Traps should be tested on a regular basis -- or the neglect may be quite costly.    

Lighting

Outdoor area lighting can be defined as streets, roadways, parking lots and pedestrian walkways. These applications have been subjected by conventional lighting technologies such as high-intensity discharge (HID) lamps and fixtures. HID lighting has been utilized for many years in outdoor area lighting applications and have well-documented performance attributes. Today’s advancements in Light Emitting Diode (LED) technology have resulted in a new alternative for outdoor area lighting, which has several advantages over existing conventional lighting.

HVAC Systems

Launched in 2006, the TTU-IAC program provides manufacturers in the state with free energy, productivity, and waste assessments – including best practices for compressed air systems, and blowers and vacuum, as well as cooling towers and chillers. The assessments to date have provided manufacturers in the program with $27.48 million in recommended cost savings, equaling 3.82 trillion British thermal units of energy savings.

Cooling Systems

Long gone are the days when cost and performance could be the only concern for companies manufacturing refrigerated compressed air dryers using refrigerant compressors. In 2019, accelerated governmental (Europe) regulations and a global concern for sustainability have brought new considerations to the table. What is the Global Warming Potential (GWP) of the refrigerants used in dryers and what is their environmental impact?

It’s no secret that cost-cutting is now a main focus for many business owners. When times get tough, the first reaction is figure out where it’s possible to spend less in order to maintain the bottom line. Over the last year, there have been countless examples of companies that eliminated programs, slashed entire departments, and sliced into salaries to protect profits.
Temperature control of the musts during the fermentation process is required for the production of high quality wines. Alcoholic fermentation is the chemical reaction in which yeast is used to transform the natural sugars of the fruit into alcohol. The heat generated by this exothermic reaction has to be managed. If must temperatures are allowed to reach the 85°F to 105°F range the reaction will be stopped. This results in high sugar content and an unstable product that requires the addition of sulphur dioxide (SO2) to allow it to be stored without spoiling. In general, optimal fermentation temperatures are 65°F - 68°F for white wines and 77°F for red wines.
Growing operational costs and lower than average occupancy rates spurred Apple Farm Inn and Suites, San Luis Obispo, Ca., to explore economic and facility efficiency benefits obtained through the installation of an ozone laundry system. At the Apple Farm Inn laundry facility, an evaluation was conducted in late 2006 to early 2007, comparing the costs of laundering by traditional methods versus ozone laundering.
Industrial plants are major consumers of water. Water is used in many processes. Sustainability projects focus on reducing the consumption of water and the energy-costs associated with cooling water so it may be effectively used.
This major mill complex upgraded their compressed air system and thereby eliminated $500,000 in annual rental compressor costs, reduced annual cooling-water costs by $500,000, and reduced electrical energy costs by $135,000 per year.
A paper mill in Wisconsin reduced its’ yearly water consumption by 547.5 million gallons and reduced its’ yearly air compressor maintenance costs by $470,000.  
This article reviews two major processes in paper mills: compressed air quality and air compressor cooling.  The central air compressor room was expanded and relocated at the largest privately owned paper mill in Canada.  The compressor space was required by a plant expansion, which would occupy the original compressor space for increased production.
This paper presents a discussion on the topic of Electric Demand Management as it relates to electric tariff rates, new power generation, and incentives to curtail peak usage.
Compressed Air Best Practices interviewed Mr. John Malinowski, Senior Product Manager-AC Motors, Baldor Electric Company.
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.
