ISO 52016-1:2017 specifies calculation methods for the assessment of:
a) the (sensible) energy need for heating and cooling, based on hourly or monthly calculations;
b) the latent energy need for (de-)humidification, based on hourly or monthly calculations;
c) the internal temperature, based on hourly calculations;
d) the sensible heating and cooling load, based on hourly calculations;
e) the moisture and latent heat load for (de-)humidification, based on hourly calculations;
f) the design sensible heating or cooling load and design latent heat load using an hourly calculation interval;
g) the conditions of the supply air to provide the necessary humidification and dehumidification.
The calculation methods can be used for residential or non-residential buildings, or a part of it, referred to as "the building" or the "assessed object".
ISO 52016-1:2017 also contains specifications for the assessment of thermal zones in the building or in the part of a building. The calculations are performed per thermal zone. In the calculations, the thermal zones can be assumed to be thermally coupled or not.
The calculation methods have been developed for the calculation of the basic energy loads and needs, without interaction with specific technical building systems, and for the calculation of the system specific energy loads and needs, including the interaction with specific systems. The hourly calculation procedures can also be used as basis for calculations with more extensive system control options.
ISO 52016-1:2017 is applicable to buildings at the design stage, to new buildings after construction and to existing buildings in the use phase.
NOTE Table 1 in the Introduction shows the relative position of ISO 52016-1:2017 within the set of EPB standards in the context of the modular structure as set out in ISO 52000-1.

This document specifies requirements and test methods for room temperature sensors used to control the room temperature.
This document is applicable to wall mounted and flush mounted room temperature sensors.
The following aspects are not covered by this document:
- pendulum temperature sensors;
- ceiling mounted temperature sensor;
- extract air temperature sensors.
NOTE The measured value available at the output of the sensor is influenced by the place where the sensor device is located and factors such as air velocity, wall temperature, self/waste heating of the device and the air temperature. The perceived temperature, which is important for the well-being of a person, depends among other factors on air temperature, temperature of the surrounding walls and air flow rate as indicated in EN ISO 7730.
The temperature sensor element can be combined with other sensors in one device. This document only deals with the room temperature sensing of this devices. Other sensors are not covered except of their influence on the room temperature sensing (e.g. self-heating).
This document specifies sensor characteristics contributing to the determination of the control accuracy of individual zone controller according to EN 15500 1.
