The repairs have been completed on this project and your room and lab temperatures should be back to normal. Please let us know if you are having any issues and thank you for your patience and understanding. From: Bnc-facility-notice [mailto:bnc-facility-notice-bounces@ecn.purdue.edu] On Behalf Of Kuhn, Jeffrey G Sent: Friday, February 23, 2018 7:08 AM To: 'bnc-facility-notice(a)ecn.purdue.edu' <bnc-facility-notice(a)ecn.purdue.edu> Subject: [Bnc-facility-notice] Second Floor Heating Water Shutdown Next Wednesday! Importance: High All, This is important notification of an upcoming shutdown to replace a leaking dielectric fitting on the circulating hot water loop serving the second floor west side laboratories, offices, and galley. The leak is located above the ceiling tile in the hallway outside of Lab 2283. We have taken measures to stop the leak for the short term, but they are temporary fixes and will not hold for long. We plan to make permanent repairs on Wednesday 2/28/18 beginning around 8:00 AM. In order to repair the leak, we will have to drain the loop, replace the fitting, refill the loop, and bring it back up to temperature. This could take eight hours or perhaps more. We aren't able to accurately estimate the required time since this has not been done before. Again, only the second floor west quadrant of the building will be impacted. During the repairs, there will be no hot water reheat available in the affected areas. This means that the supply air coming from the diffusers in the labs and offices will be a constant 55 degrees F. Offices will be cold, but the bigger concern is how this will affect process equipment in the labs. If the labs have a high ambient heat load, they may not notice much difference. However if the ambient heat load is low, the lab will almost certainly cool down. Condensation may also be a possibility. Please review your equipment and let us know as soon as possible if you foresee any issues that would result from this shutdown. Please "reply all" to this email since I will be out of town all next week. That will ensure that your concerns are noted by the appropriate people.

Additional Bike rack - west side of Birck

Everyone, We have placed an additional bike rack on the west side of Birck on the cement slab next to the west parking lots. Please note that you should be using that bike rack and not the sign posts. Bikes should be parked only in designated areas. Improperly parked bikes (i.e. bikes parked anywhere other than a bicycle rack) are subject to removal. Please let me know if you have any questions. Thank you, Mary Jo Totten Logistics Coordinator Birck Nanotechnology Center Rm. 1220 1205 West State Street West Lafayette, IN 47907-2057 (765)496-1173 "Attitude is a little thing that makes a big difference." - Winston Churchill
