This document specifies procedures and conditions to enable the heat flow in water-based and electrical 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 flow density between water or electrical heated layer and space, the associated nominal medium differential temperature, and the field of characteristic curves for the relationship between heat flow density and the determining variables are given as the result. This document is applicable to water-based embedded surface heating and cooling systems in residential, commercial and industrial buildings. This document is also applicable for electrical heated embedded systems. The methods apply to systems integrated into the wall, floor or ceiling construction without any open air gaps. It does not apply to ceiling mounted panel systems with open air gaps which are not integrated into the building structure.

ISO 18523-2:2018 specifies the formats to present the schedule and conditions of zone and space usage (referred to as input data of energy calculations) for residential buildings. The schedule and conditions include schedules of occupancy, operation of technical building systems, ventilation rates, hot water usage, usage of appliances and internal heat gains due to occupancy, lighting and appliances. The schedule and conditions for lighting are applicable to fixed installed lighting fixtures. ISO 18523-2:2018 also gives categories of residential building, zone and space according to differentiating schedule and condition. For residential buildings or its housing units which contain any category of space or zone of non-residential buildings, ISO 18523‑1 applies. Depending on necessary minuteness of the energy calculation, different levels of schedule and condition from the view point of time and space averaging are specified. The values and categories for the schedule and condition are included informatively. NOTE The schedule and condition in this document is basically different from assumptions in order to determine the size of technical building systems in the process of design, where possible largest or smallest values are assumed. Instead, most usual and average values, which are assumed for the building energy calculation, are dealt with in this document.

The set of EPB assessment standards produces a great number of overall and partial EPB indicators as outputs. ISO 52003-1:2017 provides general insight to both private parties and public regulators (and all stakeholders involved in the regulatory process) on how to make good use of these outputs for different purposes (post-processing). ISO 52003-1:2017 describes the relation between the EPB indicators and the EPB requirements and EPB ratings, and it discusses the importance of project-specific, tailored values as requirement or reference for certain EPB indicators. ISO 52003-1:2017 also includes a couple of possible EPB labels and it lists the different steps to be taken when establishing an EPB certification scheme. ISO 52003-1:2017 provides standardized tables for reporting in a structured and transparent manner the choices that are to be made with respect to overall EPB requirements. The tables are non-restrictive, thus allowing for full regulatory flexibility. ISO 52003-1:2017 does not provide such tables for partial EPB requirements (related to the fabric or technical buildings systems), as this is dealt with in other documents. NOTE Table 1 in the Introduction shows the relative position of ISO 52003-1:2017 within the set of EPB standards in the context of the modular structure as set out in ISO 52000-1.

ISO 16814:2008 is intended to specify methods to express the quality of indoor air suitable for human occupancy, to allow several acceptable target levels of indoor air quality, depending on local requirements, constraints and expectations. ISO 16814:2008 applies to the design of new buildings and their systems and the retrofit of existing buildings and systems, indoor environments where the major concern is that of human occupants, buildings having any combination of mechanical and natural ventilation, commercial and institutional buildings. ISO 16814:2008 does not apply to residential buildings, industrial buildings and hospitals although those parts of such buildings that are similar to commercial buildings are covered. The requirements of ISO 16814:2008 might not achieve acceptable IAQ for all people in all buildings, due to one or more of the following sources of uncertainty. The outdoor air brought into the building can be unacceptable or might not be adequately cleaned. Indoor air has a wide diversity of sources and contaminants. There are many factors that affect occupant perception and acceptance of IAQ, such as air temperature, humidity, noise, odours, lighting and psychological stress. There is a range of susceptibility and preference in the population.

ISO 14908-1:2011 applies to a communication protocol for local area control networks. The protocol provides peer-to-peer communication for networked control and is suitable for implementing both peer-to-peer and master-slave control strategies. This specification describes services in layers 2 to 7. In the layer 2 (data link layer) specification, it also describes the MAC sub-layer interface to the physical layer. The physical layer provides a choice of transmission media. The interface described in ISO 14908-1:2011 supports multiple transmission media at the physical layer. In the layer 7 specification, it includes a description of the types of messages used by applications to exchange application and network management data.

ISO 14908-2:2011 specifies the control network protocol (CNP) free-topology twisted-pair channel for networked control systems in local area control networks and is used in conjunction with ISO 14908-1. The channel supports communication at 78,125 kbit/s between multiple nodes, each of which consists of a transceiver, a protocol processor, an application processor, a power supply and application electronics. ISO 14908-2:2011 covers the complete physical layer (OSI Layer 1), including the interface to the Media Access Control (MAC) sub-layer and the interface to the medium. Parameters that are controlled by other layers, but which control the operation of the physical layer, are also specified.

ISO 14908-3:2011 specifies all the information necessary to facilitate the exchange of data and control information over the power line medium for networked control systems used in conjunction with ISO 14908-1. ISO 14908-3:2011 establishes a minimal set of rules for compliance. It does not rule out extended services to be provided, given that the rules are adhered to within the system. It is the intention of ISO 14908-1:2011 to permit extended services (defined by users) to coexist. Certain aspects of ISO 14908-3:2011 are defined in other documents. These documents are referenced where relevant. In the case where a referenced standard conflicts with ISO 14908-3:2011, the latter will prevail.
