EN ISO 52016-1:2017(Main)

Energy performance of buildings - Energy needs for heating and cooling, internal temperatures and sensible and latent heat loads - Part 1: Calculation procedures (ISO 52016-1:2017)

SIST EN ISO 52016-1:2017

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.

Components for BAC control loops - Valve and actuator assemblies - Part 1: Water-based HVAC applications

SIST EN 17691-1:2026

This document specifies requirements and test methods of valve-actuator assemblies in individual zone control of water-based HVAC applications.
This document does not apply to control valves of nominal diameter larger than DN50.
This document is applicable to pressure independent and pressure dependent control valve-actuator assemblies of relevant categories: 2-port, 3-port and 6-port valves (if they incorporate a control valve function).
Where a certain control loop as a combination of controller and valve-actuator assembly was assessed under EN 15500-1 [3], this document allows the assessment of the performance of combinations of that controller with different valve-actuator assemblies. The tests in this document ensure that valve/actuator assemblies, as components of control loops, can be replaced with products that provide comparable or better performance.
In hydronic system, valve-actuator assembly is a component of control loop that controls water flow rate according to the application control demand.
