Why should you use PD CEN/TR 16798‑2?
PD CEN/TR 16798‑2 is a guide to EN 16798-1 and can help the user in the application of the standard and give additional background information. Besides PD CEN/TR 16798‑2 describes and recommends additional topics related to the evaluation of the indoor environmental quality and new possibilities to improve the indoor environmental quality and reduce the energy use of buildings like personalized systems, air cleaning technologies, consideration of adapted persons, etc.
By adapting PD CEN/TR 16798‑2 users can understand how design criteria can be established and used for dimensioning of systems. It explains how to establish and define the main parameters to be used as input for building energy calculation and long-term evaluation of the indoor environment.
PD CEN/TR 16798‑2 also describes how gas-phase air cleaning in the future can improve indoor air quality and partly substitute for outside air. Finally, it will identify parameters to be used for monitoring and displaying the indoor environment.
