‘Go Green’ QuestionsNovember 2009
1. Please clarify consumption reduction year-to-year. Under the section titled "Natural Gas:" the "Pounds of Steam Produced:" has increased 13% yet consumption is stated to be down 13%. What am I missing in this statement? Thanks for the information, good stuff!
Many are scratching their heads after reviewing the Natural Gas Steam production numbers from our last news letter…..the intent of this column was to show that the Heating Plant produced more steam by consuming less gas; which means the boilers were operating approximately 13% more efficiently during the month of July this year when compared to the month of July last year.
2. Your answer seems to miss the point – that most places in the building are too cold. In many places you are missing your target by 10 degrees. I just teach occasionally in NSF 3202 or another room, but it is often too cold as well. I would suggest that this coming summer you institute a comprehensive program to insure that your target temperatures are being reached a high percentage of the time. I would also suggest that the optimal temperature you have adopted is too low, and that it should be at least up to 72, and maybe 72-74. This latter step is something that should be discussed with all parties, especially those occupying the building in the summer, and those of you responsible for the air handling and cooling equipment. A major decision like this also needs to be on the table before many faculty leave campus around the first of May.
The New Science Facility’s mechanical systems have the flexibility to satisfy many target temperatures if all the system variables are working together properly. Over the past summer, the mechanical system did have some issues that the Facilities staff addressed. Please note that all classrooms and every third office have an adjustable thermostat…If adjusting the thermostat in an office or classroom does not correct the situation; please notify Plant Operations promptly (x2292) with the complaint and our staff will address the issue.
3. Did anyone see the discrepancy regarding NSF being newest and most efficient and then later costing the most???
The energy cost per square foot comparison previously shown between NSF and Jamrich Hall was meant to display the difference in cost between the types of facility usage and not to measure the cost efficiency between campus buildings. The square foot cost is higher in NSF because of the operating requirements of a laboratory facility; versus, the demands of operating an academic classroom facility such as Jamrich Hall. The reference to "efficiency" was in regard to the operation of the NSF building as compared to other laboratory facilities. Even though the NSF building is more expensive to operate than Jamrich, it does operate more efficiently when compared to buildings of its same type.
4. The outside doors on the west side of Hedgcock (under the hamster tunnel) stay open often because of the wind. It would make sense to either replace them with doors that open from the other direction or to unlock them half way, i.e. you would need to turn the handle or push the bar to use the door.
Thank you for the information. Facilities will review the situation and suggestions offered.
