GRENVILLE KENNETH YUILL

It is with great sadness that we announce the death of our husband and father, Dr. Grenville Kenneth Yuill, aged 83. He died peacefully, with his wife, Pat, by his side on January 17, 2021, following a respiratory infection (which was not COVID).
Gren was born in Winnipeg May 18, 1937 to Grenville Yuill (1907 to 1984) and Anne (Gray) Yuill (1910 to 1968). He attended Daniel Macintyre and studied Engineering at the University of Manitoba before winning the Athlone Fellowship to the London School of Economics and Birmingham University in the UK. He became professor of Mechanical Engineering at University of Manitoba at age 24. After 13 years (during which he achieved his PhD) he started a company focused on energy efficiency and solar energy. His companies also manufactured Heating, Ventilation and Air Conditioning (HVAC) equipment and a radon mitigation system he invented. He was a past chairman the Solar Energy Society of Canada.
In 1989 he took on a new adventure, returning to academia at Pennsylvania State University. He then went to University of Nebraska in 1997 to start a new Architectural Engineering program. He went on to become the first director of the Durham School of Architectural Engineering and Construction. He retired to New Mexico in 2011.
He was fearless, original and adventurous, whether camping when it was -40° C, jumping between ice flows as the Assiniboine broke up in spring, or travelling to unusual countries off the beaten path. He returned every year to hunt moose in northern Manitoba until age 82. He balanced his work with canoeing, flying gliders, hang gliding, bungee jumping, hiking, travelling and skydiving. He was the first in Manitoba to skydive from a hot air balloon.
Most of all, he loved his family and delighted in their company and their many accomplishments. He was a kind and fun-loving father and friend to each of his children. He will be greatly missed by all who knew him.
Gren was married to Barbara (nee Perkins) of Winnipeg from 1959 to 1992 and to Dr. Patricia Draper from 1995 until his death. In addition to Pat and her children, Sarah and HB Harpending, he leaves behind son Kevin (Bridget), granddaughters, Bessie and Ellie of Durham, UK; son Mark (Krista) of Winnipeg; son David (Lily), granddaughters, Violet and Florence of Omaha; daughter Katie (Gavin), grandchildren, Calum and Saphira of Leduc, AB; brother David (Beverley) of Winnipeg, and many nieces and nephews. He was predeceased by his brother Ken.

Condolences & Memories (3 entries)

  • In the late 1960’s when Gren was teaching at the U of Manitoba, he taught me thermodynamics. My recollection is that he had recently been to Cuba, sported a Castro style beard and smoked Cuban cigars. In the late 1970’s when Gren was in the engineering consulting business, he employed me on a range of energy efficiency projects. He generated new research ideas almost daily and was very successful at convincing government agencies that they should fund his ideas. More than forty years later I am still with the firm he hired me into, still having fun doing oddball energy efficiency and building science projects. Thank you, Gren. In the late 1980’s when Gren was at Penn State and was active in ASHRAE at Society level, I decided to get involved in ASHRAE. He appointed me secretary to a committee he was chairing. Because of his contributions to ASHRAE, his endorsement eased my entry into a community that has since given me valued friends and contacts around the world and provided me many interesting opportunities. It was in ASHRAE that I most enjoyed Gren’s energy and off-the-wall ideas, because I didn’t need to worry that he would score funding for some harebrained, impossible idea that I would be tasked to complete. He brought his absurd sense of humour into the committees he served on, lightening up what could otherwise be a tedious grind. Thank you, again. Gren was an enjoyable and interesting character with a zany way of seeing the world. He was never mean spirited, even when he had a serious gripe with someone. I don’t think he had a mean bone in his body. I only knew one person that disliked Gren - a fellow faculty member from Penn State. That guy argued that the recognition Gren got for his contributions on ASHRAE codes and standards (his contributions were significant) was not deserved, as was the funding he scored for research at Penn State but most egregiously, Gren negotiated an annual leave to go moose hunting while at Penn State… all things for which I thought Gren should be admired. It was a privilege to know and work with Gren. He will be missed. - Posted by: Bert Phillips (friend, colleague) on: Jan 26, 2021

  • Barb, Kevin, David, Mark, Katie and Familes, I was very saddened to to learn of Gren's passing. My deepest condolences on the the loss of Gren. He was a very loving family man and will truly be missed. - Posted by: Terry Kjartanson (Family Friend) on: Jan 26, 2021

  • I first knew Gren when I was an undergraduate and former student of his when I was studying Mechanical Engineering at the U. of Manitoba, and he was one of our professors. Not only was he a good teacher, he was an engaging and entertaining guy after teaching hours and we attended a number of extra-curricular events together. His then-famous "flame-throwing" gig was always a big hit! Gren helped me in no small measure to secure, as he had done some years before, an Athlone Fellowship to pursue post-graduate studies in the UK. That was one of the greatest experiences of my life as I not only achieved my Masters Degree in Thermodynamics there (also at Birmingham University), but met and married my lovely and loving wife Christine, to whom I've been married now for 55 years. After I returned from the UK and was looking for a job, Gren managed to get me a temporary position at the U. of Manitoba, working as his assistant on a research project he had secured. That led to a faculty teaching position in the Dept. of Mechanical Engineering, where Gren and I then worked as colleagues for another year until I accepted a job offer with Atomic Energy of Canada Ltd. in Pinawa, Manitoba, where I remained for the rest of my career and where Christine and I and our children and grandchildren still live. After that, I never saw Gren again, but from time to time, heard small bits about where his own career had taken him. I and my family owe so much to Gren and I'm very saddened to hear of his passing. He was one of the good guys. - Posted by: Les Crosthwaite (Friend, former student and colleague) on: Jan 23, 2021
