Go iServ! iSERVcmb (Inspection of HVAC systems through continuous monitoring and benchmarking)
There are many types of certifications for air handling components, such as Eurovent or Passivhaus certification, most of them are desirable though not so easy to achieve. The user or owner of the building receives confirmation that the air handling component is one of the good ones on all aspects: energy, air quality and the environment, etc. Once the component is installed as part of the HVAC (Heating, Ventilation and Air-Conditioning) system in the building, the HVAC system must be commissioned and physically inspected as required by the articles relating to energy efficiency in EPBD (Energy Performance of Buildings Directive, 2010) if within the EU.
When looking at energy efficiency in buildings, it is always important to address the entire HVAC system and its performance in the building. Nowadays, buildings and systems must be energy‑efficient, but there is a lack of documentation about the actual energy performance of buildings and various types of HVAC systems. Not to even mention what the indoor air quality (IAQ) is like.
The new project iSERVcmb (Inspection of HVAC systems through continuous monitoring and benchmarking) aims to achieve energy reductions of 5‑40% in real HVAC systems. Over 1,600 HVAC systems in more than 16 European countries will be continuously monitored to document and benchmark HVAC energy use related to building activities and locations. Not only that, IAQ measurements will be performed in a cross section of the buildings. After all, energy efficiency without good IAQ is useless. The project will empower owners to understand the energy usage in buildings by using less expensive monitoring than inspections, and it will reward the building owners when benchmarking shows low‑energy use. In the future, it could be the case that building owners who do not monitor their building’s performance will be forced to have inspections, the cost of which is likely to be much higher than monitoring. This form of benchmarking is based on real systems in buildings and it will show the buildings which not only use best in test components, but also the reality of their systems energy usage. This form of benchmarking will provide energy consciousness and reveal the good practises in real HVAC systems.
All this would mean that low‑energy HVAC solutions and various energy‑efficient systems will be fairly evaluated and their use will be encouraged across Europe along with supporting the HVAC system performance in European legislations. It can also promote understanding of where improved performance can be achieved in buildings. All this would improve understanding of indoor climate and the energy performance of HVAC systems in buildings, and reduce Europe´s dependency on external fuel resources.
