What is PD CEN ISO/TR 52127-2 about?
PD CEN ISO/TR 52127-2 is the second part of multiple series that contains information to support the correct understanding, use and adoption of ISO 52127-1.
PD CEN ISO/TR 52127-2 consolidates information that is considered important for users to properly understand, apply and nationally adopt the EPB standards.
PD CEN ISO/TR 52127-2 is dedicated to controlling strategy and technical building management issues covered by ISO 52127-1.

Who is PD CEN ISO/TR 52127-2 for?
PD CEN ISO/TR 52127-2 on the energy performance of buildings is useful for:
- Construction industry 
- EPB members 
- A building owner or individual owner 
- Operator, a mechanical or technical supporter of BMS software 
- Architects 
- Civil engineer 
- Regulatory authority  
Why should you use PD CEN ISO/TR 52127-2?
Technical building management systems are implemented to realize an overall building operation strategy by interdisciplinary orchestration of building energy systems (heating, cooling, ventilation, lighting) whereas systems are controlled by BAC functions. ISO 52120-1 describes two approaches, how to evaluate the contribution of building automation and how to control the energy performance of buildings.
The key role of building automation and control and TBM is to ensure the balance between the desired human comfort which should be maximal, and energy used to obtain this goal which should be minimal.
PD CEN ISO/TR 52127-2 provides two approaches. One is the effect of building automation and control (BAC) and technical building management (TBM). It includes several categories that help you to characterize control accuracy, function, a strategy of the energy performance of a building.
PD CEN ISO/TR 52127-2 provides time step methods that are compatible for any time step i.e., yearly, monthly, hourly, or the statistical BIN method can be applied to help you to quantify the impact of technical building management and building automation and control on the energy performance of a building. It also provides a rationale method that is useful for detailed energy performance analysis of a building in case detailed information about the building, the HVAC system and especially the type of automation, control and management functions is available and that this information can be applied in a holistic EPB calculation method.
Therefore, PD CEN ISO/TR 52127-2 consolidates information that is considered important for you to properly understand, apply and nationally adopt the EPB standards.
