TTMD also facilitates knowledge and technology transfer and harmonizes guides via Technical Committees which are Digitalization, Commissioning, Indoor Environment Quality, Covid-19, Building Performance Simulation, Energy Management, Energy Storage and Heat Pumps, Equality, Water, Young Professionals and CWEEL.
TTMD represents the Turkish engineers and architects in international platforms and keeps contact with international professional organizations, follows the technological developments and transfers knowledge to its members and society. TTMD has become a member of AASA (ASHRAE “American Society of Heating, Refrigerating and Air-Conditioning Engineers” Associate Society Alliance) in 1997, of REHVA (Federation of European Heating and Air Conditioning Associations) in 2000, of CLIMAMED (Joint Organization of HVAC&R Associations of France, Italy, Portugal, Spain) in 2009 and of EHPA (European Heat Pump Association) in 2021. As being Turkish Chapters, TTMD also represents and cooperates with IBPSA (International Building Performance Simulation Association) since 2018 and AEE (The Association of Energy Engineers) since 2019.
Moreover, TTMD has been appointed to represent Republic of Turkey in International Energy Agency (IEA) Solar Heating and Cooling Technology Collaboration Programme (IEA SHC TCP), IEA Energy Conservation through Energy Storage Technology Collaboration Program (IEA ECES TCP) and Energy in Buildings and Communities Technology Collaboration Program (IEA EBC TCP) by the Ministry of Energy and Natural Resources, Turkey.
In addition to the seminars, webinars and courses regularly organized, TTMD brings professionals in its annual workshops, symposiums and congresses, publishes journals, books, and manuals containing recent information, develops projects targeting to combat against climate change, energy efficiency, Nearly Zero Energy Buildings and takes part actively in regulatory and standardization works. TTMD regularly holds “International HVAC+R Technology Symposium” and “International Sustainable Buildings Symposium” bi-annually and also at least one workshop annually to discuss a selected topic in detail with actors of the sector. TTMD also organizes the biggest HVACR EXPO of the Region in cooperation with other industry associations bi-annually. In addition to these, TTMD participates in domestic and international fairs and congresses regarding the sector and also supports the dissemination and publication of such activities.
