Check out the video teaser from our workshop on “Understanding of the HVAC Operational Performance” at the CLIMA Conference 2016. The presenters are Ian Knight, John Woollett and Petra Vladykova Bednarova. The workshop was attended by total of 40 attendees (mainly from Europe) and it was a good mix of practitioners (engineers, designers), manufacturers (mainly HVAC and BEMS) and people from educational institutions (universities). The concept of the workshop was to discuss several points which the presenters have considered to be of importance, such as data at operational level versus legislative needs and the use of monitoring data in future legislation.
The impending requirements for nearly Zero-Energy Buildings (nZEB) needs the efficient consumption of energy by services. This presents requirements for data to support understanding of how to achieve this in practice. This participatory workshop explored the potential for informative and practical guidelines for the operation of buildings and input for the building regulations. It has been discussed what information and data are needed, how they should be provided, and how
they might be applied with regards to updating of a number of standards in this area. Data from operational performance of HVAC systems and components (results from the project iSERVcmb) needs to provide information about what can be achieved in the building ́s operation. In the workshop the focus was on operational data from HVAC systems/components, what can be found from the data at the operational level in contrast to legislative needs, and what opportunities exist to improve the operational performance of HVAC equipment/systems. The discussion topics were focused on: Standards and legislation (LOT 6, EPBD, EN/CEN); Operational performance – real data (IAQ,power and energy use); Operational level versus legislative needs; and Opportunities in the operational performance of HVAC systems/components.
