Digitalising buildings and ensuring economical operations with solutions from SCHELL

8-minute read

In its study on the role of digitalisation in the construction sector, the German Energy Agency (dena) identified digitalisation as a significant factor for greater energy efficiency in both residential and non-residential buildings. Alongside optimisation options for water and energy efficiency, a key advantage of digitalisation buildings lies in the greater cost-effectiveness of building operations. This applies in particular to drinking water installations that are planned and operated responsibly. Where building operators digitalise key functions in the building’s sanitary facilities – such as by installing the digital SCHELL SWS Water Management System, for example – this relieves the Facility Management team of many routine tasks, freeing up their resources for other activities. In many cases, this can help to economise on staff expenditure. SCHELL has a range of solutions for the tradespersons, planners and architects involved in the digitalisation and responsible planning of a building.

Digital project planning with SCHELL’s BIM – BIM/CAD service

Building digitalisation starts with digital planning. Building information modelling (BIM) describes a method that brings together the various planning processes in architecture, structural safety and building services. In this approach, all of the available relevant data is collected, combined and modelled digitally. Tradespersons, planners and architects now increasingly make use of BIM to create new-build or renovation projects as digital assets. This allows all of the trades working on a new-build or renovation project to use a single software package and organise their planning more efficiently. This allows the identification of overlaps as well as potential savings, and optimisation of the cost-effective use of solutions over the building’s entire lifecycle. 
How SCHELL’s BIM Service helps out: When it comes to digital building planning, data in all of the relevant formats can be accessed for many SCHELL products. This data is integrated with and accessible from PARTcommunity host Cadenas. Anyone who does not yet have an account can also use the SCHELL website to set up an account here, and then access all of the formats and download data packages. Whether Revit, AutoCAD, IFC or NX files – if you want to use BIM to digitalise your building, the integration of SCHELL solutions is easy and flexible, thanks to the SCHELL BIM Portal and direct linking to product detail pages.

Convenient parameter setting for electronic fittings – SCHELL Single Control SSC

Operators who are digitalising their building and using electronic fittings from SCHELL have the option of using SCHELL Single Control SSC for parameter setting. This individual parameterisation is essential to ensure the efficient operation of drinking water installations. The SSC Bluetooth® module is a compact control unit that can be temporarily attached or left installed on the fitting. Various options are then available, depending on the mode chosen.
If the module is used as a temporary control unit, configuring a range of fitting parameters as well as stagnation flushes (every 24 hours or 24 hours after the last usage/flush) is then extremely easy to achieve. Another advantage is that, once set, the parameter configuration can then be transferred to other fittings of the same model. This saves the tradesperson a lot of time. If the module stays attached to the fitting, other functions then become available, like stagnation flushes using an integrated flushing calendar at/on specified times and days, including logging (logs can also be output as a CSV file). Further details of the many uses of SSC can be found here on our blog.

Centralised drinking water management – SCHELL SWS Water Management System

Operators who want to digitalise their building will benefit from an efficient water management system. Ideally, the water management system will also be capable of being integrated into a central building control system – as is the case with SWS from SCHELL. The SCHELL SWS Water Management System follows an integrated design philosophy and is compatible with SCHELL fittings for all important tapping points in a building.<br/> Building operators are responsible for maintaining drinking water quality. Ensuring an adequate exchange of water throughout the drinking water installation is important here, especially during longer interruptions in use or periods of insufficient use. If water is left to stagnate in piping for an unacceptably long time, this can favour the rapid growth of pathogenic microorganisms such as Legionella. Preventing this requires the regular and correct exchange of water. This is where digitalisation creates new and efficient options: many electronic fittings from SCHELL can be networked with SWS and can then support the maintenance of drinking water quality with automated stagnation flushes. Since fittings support both wired and/or wireless networking options, drinking water installations in existing properties can also be retrofitted easily. The SWS Server than handles their centralised programming, control and monitoring.

Simulating ‘specified normal operation’

In larger buildings with many tapping points, the piping is often generously dimensioned. Ensuring a complete exchange of water with the necessary turbulent flows requires the generation of high flow velocities in the piping system. For this, SWS is ideal, as the SWS Server can be used to consolidate fittings into groups, so as to carry out stagnation flushes simultaneously and therefore simulate specified normal operation. This also consumes less water than is involved with the traditional, manual flushing carried out by facility management – a process that is also liable to errors in both execution and documentation. SWS helps to save time – and therefore cut personnel expenditure – for these tasks.

Temperature-controlled stagnation flushes

Other SCHELL products are compatible with the integrated approach taken by SWS. As one example, the SCHELL COMFORT PT angle valve is equipped with a temperature sensor that measures the water temperature and transmits the data obtained to SWS digitally. This allows temperatures in the PWC and PWH lines to be checked: stagnation flushes can then be initiated automatically in the case of temperatures that are too high on the cold water side or too low on the hot water side. As a result, stagnation flushes can be triggered based on time or temperature. SWS also helps facility managers to comply with record-keeping requirements. All relevant data is stored in the form of tamper-proof CSV files on the SWS Server, and can also be exported as and when necessary.

SWS component – leak protection fitting

The leak protection fitting adds an extra function to the SCHELL SWS Water Management System to combine hygiene with leak protection. The fitting is ideal for all buildings with fixed usage or holiday periods – such as councils, local authorities, schools, insurance companies and sports centres. The SWS leak protection fitting uses a calendar function to ensure that the drinking water system is always sealed off – either centrally or only in certain parts – when all of the users have left the building. The fitting opens and closes automatically to perform the stagnation flushes set up in the system. This ensures hygiene and safety are maintained even in the case of longer periods of absence – like long weekends, during school holidays, etc. For unscheduled opening of the fitting, the fitting can be operated with a switch or opened manually.

Global, browser-based remote management – SMART.SWS

The innovative, browser-based SMART.SWS online service is an add-on for the SCHELL Water Management System. SMART.SWS provides remote monitoring and control functionality for SWS systems and fittings over an encrypted connection. From a single server to multiple installations, messages, calculated water consumption and much more can all be accessed via SMART.SWS. The options available to the respective user will vary according to the user role. This ensures that each user is given a user interface that is tailored to their user role and presents them with relevant data. Building operators can use SMART.SWS to monitor their properties and get facility management involved if necessary. Facility managers, in turn, can keep tabs on their own sphere of responsibility around the clock and proactively plan battery replacements for the fittings, for example. Mobile access to SWS as provided by SMART.SWS can save valuable time – and therefore cut personnel costs – in digitalised buildings.


SCHELL provides valuable infrastructure and solutions for tradespersons, planners, architects and operators wanting to digitalise their buildings. At the infrastructure level, SCHELL offers support with its BIM/CAD service that provides digital datasets for many fittings. This data can be accessed either on the BIM Portal or from the individual product pages.
At the product level, SCHELL offers a wide range of electronic fittings, whose parameters can be set conveniently using SCHELL Single Control SSC, for example. If the building automation system needs to be fully integrated with all key tapping points, then a deployment of the digital SCHELL SWS Water Management System is recommended. Comprehensive digital management of drinking water installations is provided by SWS and its innovative add-on, the browser-based remote admin solution SMART.SWS. SCHELL solutions ensure that the most important future requirements for building digitalisation in relation to drinking water installations can be implemented economically and sustainably with SCHELL.
