Monthly Newsletter - December 2020

This Month at ASHRAE Iowa

Join us for a virtual happy hour at 4:00PM on December 17 to catch up with your fellow associates and catch an update on chapter MP and RP progress this year. Link to the Zoom registration page is below.


We will continue to monitor the COVID-19 situation as we plan the January meeting. At this point it looks like it will be another virtual meeting but we will update you with more information in 2021. Have a great holiday season!


The virtual Annual Winter Conference planned for February 9-11 is planned and scheduled out. See the schedule and register at the link below.

President's Corner
Happy Holidays Iowa Chapter! I hope this newsletter finds you and your family well.
Thank you to everyone who joined our November virtual technical meeting. It was great to see everyone and get a chance to interact during the ethics portion of the afternoon. We were thankful to have Mick Schwedler present on chilled water systems and ethics.
Unfortunately, this year we will not have our annual joint chapter meeting with the Construction Specification Institute (CSI) and Sheet Metal Contractors of Iowa (SMCI). Instead, we are hosting a Membership Promotion (MP) and Research Promotion (RP) virtual happy hour on December 16th at 4pm. I hope you’ll join us to learn more about our chapter and to toast to the end of 2020!
We want to especially encourage all past Iowa Chapter presidents to join us at the December meeting for our annual past presidents’ photo. This year that photo will likely end up a screenshot of the meeting attendees, but what better way to commemorate the shift from in-person to virtual events that has happened this year. We will also be honoring David Poetting for his dedication and services as the Iowa Chapter President last year.
Keep the night of January 20th open over lunch as we will have a virtual presentation on testing and balancing by Board of Governors’ member Matt Jesson. Our test run of delivery service gift cards went well for the November meeting, so we will be doing that again for our attending members in January.
The 2021 ASHRAE Winter Conference is virtual. Visit the conference website for more information. The 2021 Region VI CRC is planned to be a hybrid event starting April 29th. At this time, all learning opportunities are planned to be available online, so it’s another great chance to get some PDHs.
The members of the ASHRAE Board of Governors would like to extend well wishes to you and your families this holiday season and we look forward to continuing to serve you in 2021.

What's New in the Iowa Chapter?

LEED Training Discount for ASHRAE Members - If anyone is looking for LEED Certification, ASHRAE Iowa members have been offered a $50 discount for a program through LeadingGreen training. Please reach out to for more information.

Food Bank Efforts & "Pack the Pantry"

A joint effort with local industry, local government, Iowa State University Extension, and our chapter has helped over 100 grant applications secure nearly $450,000 in funding for walk in coolers projects at local food pantries. Applicants can receive up to $10,000 to increase refrigeration capacity making more perishable, locally-grown foods available to their customers. A special thanks to Justin Barrett, Tim Conrad, and Jon Scanlan with HyVee for spearheading the efforts to assist with this program.

2020 History Project is Ready!

Check out the latest history project that Brian Steffens put together. He helped organize and albumize all of our past photos into one location for viewing – our website!

If you want to find the page on your own, go to the Committee menu, History and Photo Album History. From there, click on any of the many albums created to view the photos.

Have some old ASHRAE related photos you want to share? Send them to Brian or get them to any one of the board members. We’ll get them added to our archive and posted so everyone can enjoy them for years.

Industry News

Turbomachine Expander Offers Efficiency, Safety for Heating, Cooling
Purdue University researchers developed a device to decrease energy consumption of the vapor-compression heat pump cycle, which is commonly used in homes, businesses and vehicles for cooling and heating. The team created a novel turbomachine expander that helps harvest previously wasted energy used in the process of moving the air from high to low pressure. The device can be used as a control agent within an existing heat pump. Read more
Astronauts Replace Coolant Pumps on International Space Station
Two astronauts spent more than six hours installing replacement coolant pumps during a spacewalk on Monday. The astronauts attached the 350-lb (159 kg) pump module to the 6.8 metric ton Alpha Magnetic Spectrometer (AMS), plugged in power and data cables and spliced together eight existing coolant lines. The AMS was not designed to be serviced in orbit, so connecting the coolant lines while working in pressurized spacesuits was especially challenging. Read more
MIT Creates System that Cools Without Using Electricity
A new system provides cooling with no electricity by using the process of radiative cooling. The device, which has no moving parts, uses an aerogel insulation that blocks and reflects visible rays of sunlight. The system can keep fruits and vegetables from spoiling and can help double the time the produce remains fresh in remote places where reliable power for refrigeration is not available. Read more
Thermal Comfort Model Measures Body Shape With Sensors
A team at Carnegie Mellon University has created the first model that combines environmental information with data on an individual's body shape to determine thermal comfort. Information is aggregated to find the temperature that the most occupants possible will find comfortable. The system estimates body shape information from depth-imaging sensors, which are less privacy-invasive than approaches such as cameras. Read more
Water Battery Powers Air-Conditioning Systems
A three-story "water battery" is producing enough energy to power a university's air-conditioning systems, which is reducing its reliance on the grid by more than 40%. The water battery is a thermal energy storage system that uses energy generated by a 2.1-megawatt photovoltaic system to cool 4.5 megaliters of water resting inside a three-story tank. The campus' air-conditioning systems use the cooled water. Read more
