5 Description of the method 5.1 Output of the method This standard describes two methods of how to calculate the contribution of building automation and controls to the energy performance of buildings. The two methods are: — Detailed method: Output of the detailed method is a list of automation, control and management function types that is used to run a detailed calculation of building energy performance based on other EPBD standards. Beside this the detailed method would also allow classification of a building automation and control system according to a set of criteria defined in this standard. There is no limitation regarding the time step. — Factor based method: Output of the factor based method is the energy demand of a building according to a given building automation and control classification. The time step of the output is a yearly step. 5.2 General description of the method(s) Two methods are given: — method 1, defined in Clause 6 “Method 1 – Detailed method”, is meant for a detailed energy performance analysis of a building in case detailed information about the building, the HVAC systems and especially the type of automation, control and management functions is available that can be applied in a holistic EPBD calculation method. — method 2, defined in Clause 7 “Method 2 – Factor based method” is intended for easily calculating a rough estimate of the impact of building automation, control and management on the energy performance of a building just based on a given energy performance (either a consumption metered, or a demand calculated) correlated to a certain BAC efficiency classification of the building. 5.3 Selection criteria between the methods For the calculation of the impact of building automation, control and management functions on the building energy performance the detailed method is method 1 in this standard. The following Figure 1 illustrates how to use the detailed method compared to the simplified BAC Factor method. SIST EN 15232-1:2018

Key a delivered energy is the total energy, expressed per energy carrier (gas, oil, electricity etc.) used for heating, cooling, ventilation, domestic hot water or lighting NOTE Arrows illustrate only the calculation process and do not represent energy and/or mass flows. Figure 1 — Detailed method in comparison with BAC Factor method The detailed method should be used only when a sufficient knowledge about automation, control and management functions used for the building and the energy systems is available. The application of the detailed calculation procedure implies that all automation, control and management functions that have to be account for the operation of a building and its energy systems are known. Clause 6 gives a general survey of those functions and declares how to use them in the context of energy performance calculations. 5.4 BAC and TBM functions having an impact on the energy performance of buildings Building Automation and Control (BAC) provide effective control functions for any building energy system, e.g. heating, ventilating, cooling, hot water and lighting appliances, that lead to improve operational and energy efficiencies. Complex and integrated energy saving functions and routines can be configured based on the actual use of a building, depending on real user needs, to avoid unnecessary energy use and CO2 emissions. Technical Building Management (TBM) functions as part of Building Management (BM) provide information about operation, maintenance, services and management of buildings, especially for energy management – measurement, recording trending, and alarming capabilities and diagnosis of unnecessary energy use. Energy management provides requirements for documentation, controlling, monitoring, optimization, determination and to support corrective action and preventive action to improve the energy performance of buildings. Standard EN 15232 can be used to evaluate the contribution of these building management functions to the energy performance of buildings. SIST EN 15232-1:2018

Figure 2 — Energy demand and supply model (Example: Heating plant) Rooms represent the source of the energy demand. Suitable equipment should ensure comfortable conditions in the rooms with regard to temperature, humidity, air quality and light as needed and with due consideration of minimum or maximum requirements specified in local regulations. Supply media is provided to the consumer according to energy demand keeping losses in distribution and generation to an absolute minimum. The building automation and control functions described in Table 4 are aligned in accordance with the energy demand and supply model. The relevant energy-efficiency functions are handled starting with the room, via distribution up through generation. The most common BAC and TBM functions having an impact on the energy performance of buildings have been described and summarized in Table 4. The following Figures 3 to 7 illustrate basic system designs for heating, domestic hot water, cooling, ventilation and air conditioning purposes. The numbers refer to the control functions summarized in Table 4. These basic elements can be combined to more or less complex systems that also account for local, regional or national specifics. The building automation and control functions defined in Table 4 are according to these basic system designs. Air side system control of HVAC shall be treated as ventilation and air-conditioning control, separately from heat generators, chillers, terminal units and water and refrigerant side controls.

The control function is applied to the heat emitter (radiators, underfloor heating, fan-coil unit, indoor unit) at room level; for type 1 one function can control several rooms
0 No automatic control of the room temperature
1 Central automatic control: There is only central automatic control acting either on the distribution or on the generation. This can be achieved for example by an outside temperature controller conforming to EN 12098–1 or EN 12098–3; one system can control several rooms
2 Individual room control: By thermostatic valves or electronic controller
3 Individual room control with communication: Between controllers and BACS (e.g. scheduler, room temperature setpoint)
4 Individual room control with communication and occupancy detection: Between controllers and BACS; Demand control/occupancy detection (this function level is usually not applied to any slow reacting heat emission systems with relevant thermal mass, e.g. floor heating, wall heating) SIST EN 15232-1:2018

0 No automatic control of the room temperature
1 Central automatic control: The central automatic control for a TABS zone (which comprises all rooms which get the same supply water temperature) typically is a supply water temperature control loop whose set-point is dependent on the filtered outside temperature, e.g. the average of the previous 24 h.
2 Advanced central automatic control: This is a central automatic control of the TABS zone that is designed and tuned to achieve an optimal self-regulating of the room temperature within the required comfort range (specified by the room temperature heating set-point). “Optimal” means that the room temperatures of all rooms of the TABS zone remain during operation periods in the comfort range, to meet comfort requirements, but also is as low as possible to reduce the energy demand for heating.
3 Advanced central automatic control with intermittent operation and/or room temperature feedback control: a) Advanced central automatic control with intermittent operation. This is an advanced central automatic control according to 2) with the following supplement: The pump is switched off regularly to save electrical energy, either with a fast frequency - typically 6 h on/off cycle time - or with a slow frequency, corresponding to 24
