ASHRAE and the Institute of Refrigeration (IOR) have signed a new Memorandum of Understanding (MoU) formalizing the organizations’ relationship, which dates back more than a century. The new MoU outlines how the two groups will work together more closely and with more defined parameters to continue promoting the advancement of cooling and heating related technologies. These include research, joint conferences and meetings, training and education programs, publication distribution and chapter collaboration. ASHRAE and IOR will explore ways to make technical information more accessible to both memberships. The MoU places special focus on building and strengthening the organizations’ global networks. As ASHRAE and IOR continue growing their memberships internationally, the possibility of joint events would benefit both groups and further the impact ASHRAE and IOR have on the industries they serve.
