This document specifies a method for the energy assessment of domestic/sanitary hot water storage tanks of up to 2 000 l.
Whilst this document does not cover water heaters intended primarily for direct heating, it does allow the provision of electric heating elements for auxiliary use.
Primary heating buffer tanks are not covered by this document. Heat losses of domestic hot water storage tanks integrated into combi boilers marketed as a single unit are not covered by this document.

This standard specifies:
a) a method to estimate energy consumption based on measured values, calculation or simulation, on an annual basis for traction and hydraulic lifts on a single unit basis;
b) energy classification system for new, existing and modernized traction and hydraulic lifts on a single unit basis;
c) guidelines for reducing energy consumption of existing lifts that can support building environmental and energy classification systems
This standard only considers the energy performance during the operational portion of the life cycle of the traction and hydraulic lifts.
This Standard does not cover energy aspects, which affect the measurements, calculations and simulations, such as:
i) hoistway lighting;
ii) heating and cooling equipment in the lift car;
iii) machine room lighting;
iv) machine room heating, ventilation and air conditioning;
v) non-lift display systems, CCTV security cameras, etc.;
vi) non-lift monitoring systems (e.g.: building management systems, etc.);
vii) input power harmonics (harmonics are addressed in the EMC standards);
viii) the effect of lift group dispatching on energy consumption;
ix) environmental conditions;
x) consumption through the power sockets;
xi) lifts whose travel includes an express zone.

This document specifies methods for the testing and rating of dampers and valves used in air distribution systems with pressure differences up to 2 000 Pa.
The tests incorporated in this document will address:
— leakage past a closed damper or valve (for classification see Annex C);
— casing leakage (for classification see Annex C);
— flow rate/pressure requirement characteristics;
— torque: (see Annex A);
— thermal transmittance: (see Annex B).
The acoustic testing of dampers and valves is not included in this document. The tests specified above apply to the following:
— measurement of leakage past a closed damper or valve;
— measurement of casing leakage;
— determination of flow rate and pressure requirements;
— measurement of torque characteristics (see Annex A);
— measurement of thermal transfer characteristics to determine insulation properties (see Annex B).
NOTE Certain aspects of the dynamic performance of dampers and/or valves are dependent upon the air distribution system to which they are connected and are, therefore, difficult to measure in isolation. Such considerations have led to the omission of these aspects of the dynamic performance measurements from this document. Also, in common with other air distribution components, the results from tests carried out in accordance with this document may not be directly applicable if the damper or valve is situated in an area of non-uniform flow.

This document specifies essential characteristics and test methods for establishing constancy of performance for bidets used for domestic purpose to be used for personal hygiene and made from either ceramics or stainless steel.
Domestic purposes include use in hotels, accommodation for students, hospitals and similar buildings, except when special medical provisions are required.
Proper functioning of bidets can only be assumed when connected to a suitable drainage system (see EN 12056-2:2001 for more information). All drawings are examples only.

This document specifies procedures and conditions to enable the heat flux in water-based surface heating and cooling systems to be determined relative to the medium differential temperature for systems. The determination of thermal performance of water-based surface heating and cooling
systems and their conformity to this document is carried out by calculation in accordance with design documents and a model. This enables a uniform assessment and calculation of water-based surface heating and cooling systems.
The surface temperature and the temperature uniformity of the heated/cooled surface, nominal heat flux between water and space, the associated nominal medium differential temperature, and the field
of characteristic curves for the relationship between heat flux and the determining variables are given as the result.
This document includes a general method based on finite difference or finite element Methods and simplified calculation methods depending on position of pipes and type of building structure.

This document allows the calculation of peak cooling capacity of Thermo Active Building Systems (TABS), based on heat gains, such as solar gains, internal heat gains, and ventilation, and the calculation of the cooling power demand on the water side, to be used to size the cooling system, as regards the chiller size, fluid flow rate, etc.
This document defines a detailed method aimed at the calculation of heating and cooling capacity in non-steady state conditions.

This document establishes requirements for the installation of embedded radiant heating and cooling systems. It specifies general and uniform requirements for the design and construction of heating and cooling floors, ceiling and wall structures to ensure that the heating/cooling systems are suited to the particular application. The requirements specified by this document are applicable only to the components of the heating/cooling systems and the elements which are part of the heating/cooling
surface and which are installed due to the heating/cooling systems.
This document is applicable to water-based embedded surface heating and cooling systems in residential, commercial and industrial buildings. The methods apply to systems integrated into the wall, floor or ceiling construction without any open-air gaps, but are not applicable to panel systems with open-air gaps which are not integrated into the building structure.

This draft European standard is applicable to the physical and link layer parameters of baseband communication over twisted pair (M Bus) for meter communication systems. It is especially applicable to thermal energy meters, heat cost allocators, water meters and gas meters.
NOTE It is usable also for other meters (like electricity meters) and for sensors and actuators. For generic descriptions concerning communication systems for meters and remote reading of meters see EN 13757-1.
