Over the years, the demand for flexible and functional electrical installations for houses and apartments has grown on a daily basis. Changing living conditions and habits, evolving housing needs, the availability of new technologies and the awareness of the importance of efficient energy use provide the impetus for an in-depth analysis of the electrical installation.
Classic electrical installations are no longer the world standard. They no longer provide a satisfactory answer to the multitude of demands from end users for flexibility and functionality. An installation that can adapt at any time to the changing needs of the residents, expanded with customized functions that can lead to, among other things, lower energy consumption and greater ease of use, safety and care components, is now the obvious choice.

Advocating a more flexible home electricity installationLeonardo ENERGY
Today, most newly built or renovated private houses are still equipped with a rather simple electricity installation, providing not much more than a series of light points, switches and power outlets throughout the building. While this so-called base case electricity installation is very robust and safe, it is being challenged by the ever increasing expectations of 21st century homeowners and occupants. Examples of increased expectations include flexible space usage, networking capabilities, automation, remote control of HVAC and other electricity powered equipment, and adaptability of the system to meet changing needs.
In this whitepaper we outline the challenges presented to the base case electricity installation and provide a guideline for installers to help them meet the increased expectations. Aspects discussed include a gradual shift towards automation-enabled systems and an activity-centred approach of installation design. We encourage installers to grasp this opportunity and become advocates of a more flexible home electricity installation. This is also in their own interest, as it is likely to make their work more interesting, satisfying and rewarding.
The whitepaper is based on interviews with a number of home electricity system installers and representatives of electric systems manufacturers ABB, Abitana, Legrand Group, Niko and Siemens. In addition, we organized five workshops with these manufacturers and with organizations such as Tecnolec, Enter vzw and CeDuBo[i]. In this whitepaper, the participants at the interviews and workshops are referred to as ‘our expert panel’.
What does a home electrical installation cost?Leonardo ENERGY
Highlights:
* Considers what needs to be taken into account to provide a budget for a domestic electrical installation.
* Looks at necessary and optional items.
* Discusses budget as a percentage and cost per square metre.
* Calculates cost of four different installations: conventional, remote control, and integrated home system with star or bus topology.
* Finds that cost varies between 3% and 5.1% of total construction budget.
Integrated Home Systems - Chapter 1 - DefinitionLeonardo ENERGY
The term “integrated home systems” is increasingly used when referring to modern electrical installations in homes. This term also raises a few problems, however. It is a container term. Everybody has his own understanding of it. People can be at cross purposes when talking about integrated home systems, and can actually be talking about different things. A young technology needs this like a hole in the head. In order to avoid mistakes, confusion and abuse, we endeavour to define the term “integrated home systems” here. We will analyse the key words of the definition and give practical examples. We will also look at why it is now, and not 30 years ago or in 30 years’ time, that we want to use integrated home systems. We will discuss the difference between integrated home systems and building automation, and we will present the argument why we prefer not to use the term “home automation”.
A modern residential installation with an IHSLeonardo ENERGY
This white paper is one of a series of thematic white papers covering various aspects of electrical installations in houses, flats and residential units. They are aimed at architects, designers, specification writers, decision makers and students.
Over time, the electrical installation in our houses and apartments has changed. Originally there was a single lighting point in each room with a switch and a socket near the door. Then, over the years, more and more electrical appliances came onto the market and, pretty soon, the electrical installation became too small to accommodate them. Expansion with more lighting points, switches and sockets was necessary, followed by the possibilities of dimmer switches, time switches, automated stair lighting and motion detectors.
Nevertheless, the basic structure of the traditional electrical installation remained the same, but with certain disadvantages. Flexibility is non-existent, and functionality is extremely impaired: two important aspects we need today and in the future. The functions required by a young couple employed outside the home and who have children will differ from those of an elderly person living alone. These days we are much less static in the home. Doing a different job often means moving to a different place so the electrical installation must have the flexibility to satisfy our changing needs.
Today, opting for a modern electrical installation with an Integrated Home System (IHS) is no longer a luxury but a necessity. Our cars, televisions, telephones (especially smartphones) and heating systems are all already digitised to an advanced degree. It is therefore time to turn our attention to the buildings in which we live and spend most of our time. We have reached a pivotal point where the traditional electrical installation is at its end and the obvious choice is to replace it with a modern, contemporary installation with sufficient functionality and flexibility. We are at the dawn of a new era.
Integrated Home Systems - Chapter 5 - Structured CablingLeonardo ENERGY
It used to be a lot easier. At one time 230V cabling would be laid in a newly-built home, to which a few sockets, power points and switches were connected. At most, there was also a telephone socket in the wall and a coax cable connection for the television. A small distribution board was sufficient to protect a few socket and lighting circuits. The installation was ready.
Overviews the quick connectors available and their benefits over conventional installation methods.
Ideal for electrical installations in office buildings, schools, hospitals and shops.
Labour and costs are reduced, and installation flexibility is increased.
Renovations and repairs are easier.
Suggests that Plug & Play installation could become the standard installation method in the near future.
Flexibility of household electrical installations is partly necessary because people’s needs change over the time they live in a home, and because houses and flats are sometimes leased or sold. The new occupants want the electrical installation to be adaptable to their needs and wishes as far as possible.
With a strictly conventional electrical installation there is virtually no flexibility. It is usually difficult to add a switch somewhere if you are not prepared to open up the wall, to cut off and install new wiring. However, there are a number of techniques and solutions to overcome this problem, although they must be planned when the system is originally designed.
This white paper is one of a series of thematic white papers covering various aspects of electrical installations in houses, flats and residential units. They are aimed at architects, designers, specification writers, decision makers, installers and students.

Energy and mobility poverty: Will the Social Climate Fund be enough to delive...Leonardo ENERGY
Prior to the current soaring energy prices across Europe, the European Commission proposed, as part of the FitFor55 climate and energy package, the EU Social Climate Fund to mitigate the expected social impact of extending the EU ETS to transport and heating.
The report presented in this webinar provides an update of the European Energy Poverty Index, published for the first time in 2019, which shows the combined effect of energy and mobility poverty across Member States. Beyond the regular update of the index, the report provides analysis of the existing EU policy framework related to energy and transport poverty. France is used as a case study given the “yellow vest” movement, which was triggered by the proposed carbon tax on fuels.

Energy Sufficiency Indicators and Policies (Lea Gynther, Motiva)Leonardo ENERGY
This policy brief looks at questions ‘how to measure energy sufficiency’, ‘which policies and measures can be used to address energy sufficiency’ and ‘how they are used in Europe today’.
Energy sufficiency refers to a situation where everyone has access to the energy services they need, whilst the impacts of the energy system do not exceed environmental limits. The level of ambition needed to address energy sufficiency is higher than in the case of energy efficiency.
This is the 13th edition of the Odyssee-Mure on Energy Efficiency Academy, and number 519 in the Leonardo ENERGY series. The recording of the live presentation can be found on https://www.youtube.com/watch?v=jEAdYbI0wDI&list=PLUFRNkTrB5O_V155aGXfZ4b3R0fvT7sKz

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.

1. INTRODUCTION
Over the years, the demand for flexible and functional electrical installations for houses and apartments has
grown on a daily basis. Changing living conditions and habits, evolving housing needs, the availability of new
technologies and the awareness of the importance of efficient energy use provide the impetus for an in-depth
analysis of the electrical installation.
Classic electrical installations are no longer the world standard. They no longer provide a satisfactory answer
to the multitude of demands from end users for flexibility and functionality. An installation that can adapt at
any time to the changing needs of the residents, expanded with customized functions that can lead to, among
other things, lower energy consumption and greater ease of use, safety and care components, is now the
obvious choice.
Housing construction experienced a similar revolution several decades ago with the switch from individual coal
or gas heaters to central heating. Today, a central heating system is the accepted standard for a house or
apartment. New and renovated homes deserve a similar switch for the electrical installation. Integrated
installations with greater flexibility and functionality must now become the norm to ensure that installations
do not become obsolete within a few years.
This Application Note with Good Practices does not provide you as an installer with practical tips on how to lay
conduits, install distribution boards, make connections or program an integrated system. We assume you are
sufficiently well versed in the technical field. It does, however, point the way towards installations with added
value; installations where the customer is both the focal point and the starting point. Reflecting on what an
installation should be capable of for a particular building and its residents is the central theme in the text that
follows. Installing high-tech material that only offers functions that are comparable to those of a classic
installation is no longer desirable. We have to adopt a more rational approach to the use of many modern
technical possibilities and involve the user appropriately in this process.
This document aims for Good Practices in an ideal situation and for an ideal installation. In daily practice, it will
not always be easy or even possible to follow all of the suggestions included here. We do, however, hope that
the installer will follow and implement as much of the advice and suggestions as possible. This will satisfy the
customer, the architect and the installer.
This Application Note is based on several interviews with installers within the housing construction industry,
interviews with representatives of manufacturers, and five workshops on flexibility and functionality in the
home. The workshops, organized and run by the European Copper Institute (ECI), were attended by
manufacturers (ABB, Abitana, Legrand Group, Niko, Siemens) and several organizations active within the
housing construction industry or the installation world (Tecnolec, Enter v.z.w., CeDuBo). We would like to
thank all these people, organizations and manufacturers for their cooperation.

2. ABOUT FLEXIBILITY
There are a great many reasons for ensuring that a contemporary electrical residential installation possesses
sufficient flexibility. Examples include changing living conditions and requirements. A young family with small
children has different needs than those of a family with children who are studying or an elderly couple without
children. A single-parent family likewise has different needs, as does a single elderly person who requires a
little care to be able to live independently in their own home for longer.
In addition, various rooms in the home may be assigned different uses over the years. A bedroom becomes a
study for the teleworker who wants to avoid the daily traffic jams. Another room becomes a temporary or
permanent living and sleeping area for grandmother, who moves in because she’s having trouble walking,
needs temporary care, or is becoming too lonely.
New techniques and technologies are emerging and we want to integrate these into existing homes. Examples
abound. Perhaps it is an extension of the existing structure because one of the residents wants to start a
private practice as a physiotherapist or medical chiropodist. The list is virtually endless.
Below, we examine the ways in which a home’s flexibility can be increased from the installer’s perspective.
A classic electrical residential installation has extremely limited possibilities for added flexibility. Once
installed, it is difficult, if not impossible, to make changes without extensive renovation. The classic
installation is no longer able to cope with the often rapidly changing needs of residents and the new
techniques and technologies that are available.
What is needed is an installation in which integration and flexibility are possible. We are helped in this
by all manner of management, automation and integration systems. An installation with an Integrated
Home System (IHS) must be the basis and standard for any new home or major renovation. If this is
not the case, the home will be outdated and not adaptable within a few years.
When fitting manually operated shutters, the installer should also immediately provide cabling to the
distribution board. At a later phase in the building’s life, electrical shutters that can be controlled by
the IHS can then still be fitted.
Provide cabling for a sun blind and for the weather station. The IHS can then control the sun blind
automatically according to ambient light and darkness, time of day, windy conditions, rain and indoor
temperature.
For larger homes, consider installing several distribution boards. Suggestions here include one
distribution board per floor and for any free-standing garage and the garden shed. An extra
distribution board also has its place in the kitchen. When fitting a new kitchen, laying wiring for the
appliances will have less of an impact on the rest of the home.

Also consider providing sockets in the living rooms and bedrooms that can be switched on or off by
the IHS. Floor lamps and other free-standing fixtures with plugs can then easily be controlled within
lighting atmospheres.
Within socket circuits, four or five wires can be used instead of the usual 3G2.5 mm². A socket that
was previously live can be switched off at any time using these additional wires. Use only deep flush-
mounted boxes when making the connections possible.
Figure 2: Additional wires in the conduits for sockets enable additional switching or dimming
of those sockets at a later date. (Image: E&D Systems)
If PV panels have not yet been installed on the roof, provide the cabling or a shaft to the attic to allow
this to be done later.
A multifunctional, structured cabling concept, combined with a patch box for data, telephony, radio
and TV, significantly increases flexibility. Depending upon the residents’ needs, each outlet can then
be configured for a particular function (telephony, data, TV, etc.).

3. ABOUT FUNCTIONALITIES
Happily, the time when you could only operate a single light with one switch is now past. With the advent of
integrated systems, basic functionality has become much greater. With one push of a button, we can call up an
entire atmosphere that not only takes the lighting to a certain level, but also operates the shutters and heating
if required. Besides atmosphere buttons, we also have group controls (shutters), the all off button, the sleep
button and, if desired, buttons to control audio and video.
The functionality someone needs depends upon various factors, including the size of the home, the
composition of the family, the degree of comfort desired, the necessary level of security and communication,
and the way the residents live and work. The choice of functionalities to be implemented must be tailored to
all of these factors. Obviously, people should not be given functions they will never use, but rather those
functions they will make use of on a regular basis.
Experience has shown that many builders/renovators and architects have insufficient knowledge of
the current possibilities. The installer, together with the principal and/or architect, should therefore
carry out a small study to determine the needs of the residents and select the appropriate
functionalities.
The realization of needs and functionalities can take place in various ways. First, there is the
discussion between installer and principal. Identify the needs and propose functionalities based on
these findings. Make a clear note of these. They will help form the basis for preparing a quote.
A second, less time-consuming method of accomplishing this consists of using a design tool or
checklist. The principal can start on this before the discussion with the installer begins. On the one
hand, he is presented with functions with which he may presently be unfamiliar, and on the other can
tick those functions he currently wants, would like later or does not logically anticipate ever needing.
All this can be clarified in the discussion with the installer. A good example of such a design tool is the
Design Guide for Integrated Home Systems. Chapter 3 of this guide addresses the most common
functionalities. Read this chapter carefully before entering into discussions with the client.
Figure 4: In the Design Guide, the end user can choose his desired functionalities himself. (Image: ECI)
A visit to a showroom or to a home with an IHS installation can also clarify many things. In the latter
case, encourage the residents of an installed home to provide the explanation, thus highlighting first-
hand the benefits for users.

4. ABOUT NUMBERS AND LOCATIONS
There is nothing so tedious and annoying as finding that, as a resident of a newly built or renovated house or
apartment, you have too few sockets, data, telephone and TV connections, and that likely as not, they are in
the wrong place. To avoid the residents using extension cables or giving in to their DIY spirit (with possible
repercussions for the safety of the installation), it is advisable to make a considered choice of the number of
sockets, data, telephone and TV connections and their locations within the home. The same applies to controls
such as buttons and switches. There are no hard and fast rules here, but a number of tips and the use of a
checklist may help.
Figure 5: This is definitely too much of a good thing, but sufficient sockets, data, telephone, radio and TV
connections are extremely important in the home. (Image: Fotolia)
Checklists provide examples of what type and how many connections are generally provided in each room.
Many switch manufacturers provide their own checklist on their website.
The European Copper Institute (ECI) has produced its own, brand-independent checklist (Checklist for
the electrical installation in the home). It is also possible to enter figures in a spreadsheet for each
room of both a house and an apartment. Points of attention are given for each room in relation to the
possible appliances for each room.
Some tips:
Place sockets in each corner of living rooms and bedrooms.
Ideally, provide at least two sockets in every other area. This means the resident does not need to
unplug a fixed appliance to temporarily plug in another. This is less important for sockets beneath a
switch.
Provide sockets at regular intervals on long walls.
More sockets must be installed for TVs and computers. After all, several appliances are likely to be
connected here.
There will obviously be a TV connection in places where there is currently a TV. Provide another TV
connection at another point in the same room (opposite wall). This lets residents enjoy the flexibility
of moving their TV.
10. Publication No. Cu0219
Issue Date: March 2015
Page 7
Since a wired data connection is much faster, safer and more stable, sufficient data connections must
be provided. Living rooms and bedrooms should get at least one double RJ45 socket.
Consider installing multimedia cabling or a structured cabling network with RJ45 sockets and a patch
box. Thanks to the active components in a patch box, the residents can choose which socket is used
for telephony, data or TV at any time. In certain cases, separate coaxial cabling is required for the
television.
Data connections also need to be provided behind the television and the audio chain for the smart TV,
the digital TV box of the provider and for internet radio.
It may be advisable to install one or more motion detectors in passageways.
Buttons and other controls for operating lighting, shutters, heating, etc. also have a role to play.
Provide at least one control point for one or more buttons at each entrance to a room. Buttons can
also be provided in the kitchen and study for lighting the respective work surfaces.
We discuss how many buttons should be installed in a particular location in the section entitled About
integration and integrated controls.

5. ABOUT TECHNIQUES
Choices also have to be made in terms of techniques in the design phase. Does the principal want a classic
doorbell, an intercom or a videophone?
We refer here to Chapter 4 of the above-mentioned Design Guide for Integrated Home Systems. The
most commonly used techniques are briefly discussed here. The principal and/or architect can tick the
desired techniques.

6. ABOUT INTEGRATION AND INTEGRATED CONTROLS
To promote flexibility and functionality, we must work on integration. In addition to the installation for lighting
and sockets, a home consists of all types of subsystems such as shutters, sun blinds, heating, cooling,
ventilation, the LAN network, telephony, video telephony, audio and video streaming, etc. In some cases we
can talk of integration even within a single subsystem. One example of this is lighting. A lighting atmosphere,
activated by a single button, whereby we dim several separately controllable lights to different levels, is an
example of integration within the lighting subsystem. It is advisable to integrate multiple subsystems as
effectively as possible for several reasons. It can increase comfort and the possibilities for communication.
Integration with heating, cooling and ventilation in turn saves energy.
On the one hand, integration is a technical aspect of the installation. It raises questions such as what technical
means can we use to interlink subsystems? In practice, there are usually sufficient solutions available from
manufacturers. The end result of this technical integration is the possibility of performing actions with the
various subsystems via the IHS, automatically or by means of control modules (buttons, keypads, smartphone,
etc.).
On the other hand, integration also comprises a non-technical process of reflection. How can we bring
integration to the user? In practice, things often go wrong in this area. An example:
Figure 6: How many buttons should you install in this bedroom? (Image: E&D Systems)
There are three separate lights, and also one shutter, in a bedroom. The installer places five buttons
next to the entrance to this room. The first three control the separate lights. The last two buttons are
used to open and close the shutter.
In the above example, we assume that technical integration has taken place. Both the lights and the
shutter are controlled by the IHS. The problem in this example is that they are never controlled by the
same command. So there is no added value for the user compared with a classic electrical installation.
He can only do the same as with a classic installation. Technical integration is present, but nothing is
being done with it.
In addition to several necessary one-to-one buttons, it is preferable to integrate the functions in this
case. A so-called I'm going to sleep button by the door could be used when someone enters the
bedroom. This would switch the lights on and close the shutter. A I'm leaving the bedroom button
could also be provided. The lights that are on could also be dimmed to zero over a period of one
minute, the light on the landing could come on if it is too dark, and the shutter could be opened after
two minutes, for example.
What can we do to bring about user integration?
13. Publication No. Cu0219

Take into account the function of the room. Different integrated functions will be required in a
bedroom, a study or a living room.
Take into account the number of users of a room. A room where several people are usually present
will require different functions than a room that is only used by one person.
Take into account the number of entrances to a room. We may also have to integrate the entrance
hall lighting by the door of the living room into the hall. We can use a similar system at the entrance
to the kitchen from the living room.
When people enter a particular room, they have a particular intention: sleeping, reading a book,
playing with the children, cleaning, etc. Take this into account to determine what integrated functions
are needed at a particular control point and provide a control button there.
Avoid one-to-one controls on push-buttons in the wall. If these are unavoidable, place them on an IR
remote control or a smartphone app if possible.

Issue Date: March 2015
Page 11
7. ABOUT USER-FRIENDLINESS
An integrated system may be able to perform many functions, but it should be a system that is easy for the
residents to operate. The judicious assignment of functions to certain buttons is therefore extremely
important.
Design a usage system for the placing of functions on buttons and use this in each room of the home.
Example:
o In each room where several buttons are installed alongside and below each other at the
entrance to the room, the general lighting for the room can be assigned to the top-left
button.
o When leaving a room, the all off function can be triggered for that room by pressing and
holding down the bottom-right button.
o Shutter controls can always be placed on the right, for example.
o The possibilities are endless.
Only install modules on which every button performs a function. Modules on which one or more
buttons perform no function should be avoided. They only cause confusion for the user (“What’s this
button for?”).
If possible, choose buttons with lettering. Text or symbols can be applied to them that indicate to the
user what function will be performed if the button is pressed.
To limit the number of buttons, we mainly program intention functions on the buttons in the wall
(receive visit, read book, go to sleep, get up, etc.). Any one-to-one controls do not need to be placed
on buttons in the wall, but can be moved to an IR hand-held remote control, a tablet or a
smartphone.
However, for functions that have to be activated or deactivated in real time (such as audio, for
example), directly accessible buttons have to be provided. Running through a menu structure on a
smartphone or tablet to activate the mute function when the phone rings is too inconvenient and
time-consuming at that moment. Such functions must be able to be operated instantly.
For dimmed lights, it is advisable, if possible, to set a minimum dimming level at which the user can
still see that the light is on. This is important for dimmers with a memory mode. If the light can be
dimmed below the point at which the user can still see that the light is on, the user is no longer in
control. With an off function, the light will in fact be off. With a subsequent on function, the dimmer
will return to this much too low light level. At that point, however, the user cannot see a difference,
and thinks the bulb has gone or the system has stopped responding. A call to the installer will soon
follow.

8. ABOUT STRUCTURAL IMPROVEMENTS AND OPTIMIZING WORK
We are largely dependent on the architect and his design for structural improvements, and often also for
optimizing the work on the site. Below, we discuss several points that could increase flexibility and optimize
the work on the site, thus cutting building costs. Some of these will have to be proposed to the architect and
meet with his approval.
Together with the architect and the principal, explore the possibilities of providing one or more
vertical shafts in the home. These can be used at a later stage to install additional cabling to the
various floors. This could be important, for example, if the older resident(s) want to split the much too
large house into apartments, or if solar panels are only fitted at a later stage.
If possible, provisions must also be made to be able to extend horizontally. This could be a horizontal
shaft to the garden (via the cellar or crawl space). In this way, several cables can be installed for
garden lighting and sockets, for the garden shed, the terrace, the free-standing garage or carport.
False ceilings are also an excellent way of extending horizontally. Obviously these are modular false
ceilings, parts of which can be removed temporarily to install additional cabling. This could be done in
a hallway, for example. In this way, cabling can be installed between different rooms situated
alongside the hallway. Permanent false ceilings in living rooms also offer the possibility of integrating
light fittings without any problem.
The screed is normally only laid once all the tubes and conduits have been installed and when the
plasterer has completed his work. This state of affairs has drawbacks. The plasterer can damage tubes
and conduits in the course of his work. Plastering is also much easier on a level floor (on the screed)
then on an uneven base. We therefore advocate laying the screed once all the tubes and conduits
have been installed (and hence protected), before carrying out the plastering. The plasterers then
only need to place a plastic sheet over the screed to avoid dirtying it. Any additional costs for this way
of working are much less than any interventions that must be performed if a conduit or tube proves
to be damaged after the screed and tiles have been laid. After all, digging everything up is the only
option at this point.
A great many cables or tubes generally have to find their way through the ceiling above distribution
boards. Openings have to be cut or drilled in the concrete slabs for this. The size of these openings
can compromise the stability of arches. One solution consists of having the architect provide the
necessary openings above distribution boards at an early stage. He can ensure adequate support for
the various concrete slab elements without jeopardizing stability.
Since we want to integrate several subsystems with the IHS, the necessary agreements will have to be
made with the installers of the other techniques. Site meetings with all installers, together with the
architect, can be used as a tool in this regard.
o Which subsystems must be linked and controlled by the IHS?
o Which contacts, connections and cabling are required for this?
o Who delivers what and who installs what?
o Who takes charge of coordinating the integration (installer/integrator/architect)?
o Make firm agreements at the site meeting. The architect notes these down and sends them
to all technicians as a report of the meeting.

9. ABOUT THE INSTALLATION DOSSIER
An installation is only fully complete once a high-quality, usable installation dossier has been produced. A good
installation dossier for a domestic installation contains the legally required documents (such as the single-wire
diagram, the situation diagram and the agreed report for the installation inspection certificate) as well as the
following components:
The as-built plan of the conduits.
A ground plan with the location of all sensors operating on SELV and any actuators (buttons, touch
panels, motion detectors, temperature sensors, light sensors, interfaces, etc.).
A list of consumers in which it is noted to which output of the output module each consumer is
connected, with their address where appropriate.
A list with the connection of the sensors to the input modules and the address for programming.
A list or software file in which it can be verified which sensor will perform which function.
A layout of the distribution boards.
If software is used for the configuration, this software and the installation file in electronic form must
make up a part of the dossier.
Figure 8: The use of the correct symbols is vital for a good dossier. (Image: E&D Systems)
Several copies of the complete dossier should be produced.
Three copies are normally produced as standard.
o One copy (with the legally required documents) goes to the inspection body at the time of
the inspection. There is no need to attach the other components of the dossier discussed in
this case.
o A second copy (legal documents plus all additional components, including software and
installation file) is handed to the owner/resident at the time of the inspection. This dossier
must remain with the installation at all times.
o A third complete dossier is for the installer’s records. It can be used for after-sales service.
If desired, the architect also receives a copy of the dossier (including software and installation file).
The procedure for compiling a complete dossier is explained in Chapter 3 of the e-Book: Integrated
Home Systems - Chapter 3 - The System File. This also contains examples of symbols to be used for
IHS installations.
The installation dossier is not only important for the after-sales service.
Look on a dossier as a tool.
Being well-prepared is half the battle. Prepare the dossier before you begin installation on site.
Designate it as a task to your employees. A well-prepared dossier saves a great deal of time on site.
Programming the software is also easier and better in the calm environment of the planning office
than the day before delivery on site.

10. ABOUT THE RELATIONSHIP WITH THE ARCHITECT
The architect plays a vital role in the acceptance or rejection of new technologies and methods, and the
resultant flexibility and functionality for a home. It is therefore extremely important to establish a good,
sustainable and long-term professional relationship with the architect.
Try and become involved in every project as early as possible. The opportunity to make modifications
to the concept for the home is much greater if the work for the shell of the building has not yet
started than if the conduits are about to be put in place.
Always try and think along the same lines as the architect to propose customized solutions. He will
thank you for it.
Use your knowledge of materials, systems, techniques and the market situation to assist the architect.
Don’t suggest new technologies simply because they are new. Always frame the technologies to be
used in terms of the benefits to the residents.
Provide the architect with a check-list for determining functions and techniques. The Design Guide for
Integrated Home Systems can be of use here.
If necessary, make suggestions for a better workflow on the site. This includes, among other things,
clear agreements about who installs what and when, and the organization of site meetings with the
other technicians.

manner of aspects that could improve the flexibility and functionality of the installation. (Image: Fotolia)

11. ABOUT THE RELATIONSHIP WITH THE PRINCIPAL/RESIDENTS
Obviously, the relationship with the principal/residents is also very important.
Do not present yourself as a seller of techniques, but rather as a provider of tangible solutions that
will make their daily activities and life in the home more comfortable, safer, easier, etc.
Give them the Design Guide for Integrated Home Systems, and ask them to have a look through
Chapter 3 (functionalities) and tick which functions may be important to them. If desired, they can
also choose specific techniques in Chapter 4.
Invite the principal to visit a completed installation, a showroom or a concept store. However, in the
last two cases, take care that it is not just about appearance and design, but that functions can be
demonstrated.
Note down all chosen functions and techniques.
On that basis, prepare a quotation which, except for the total price, provides the necessary concrete
details. In this way, the principal knows what he will get for a particular price.
If desired, split your quotation up into a basic section (lighting, sockets, heating control, data
connections, etc.) and a section with options (shutter control, video telephony, multimedia
connection points, etc.).
At delivery, go around with the residents and demonstrate the various functions.
At delivery, provide the principal with paper on which he can note any malfunctions or problems.
Return within the first three months to make adjustments.
Keep your customers of completed installations informed of new possibilities and products for their
installation. If necessary, provide a demonstration in their home.
For large, complex installations in particular, it is interesting to work with a maintenance contract
after delivery. A yearly or two-yearly inspection of the installation can prevent problems. Certain
functions can also be adjusted.

12. ABOUT THE INSTALLER
Over the past twenty years, so many new techniques have appeared in the housing construction industry that
we understand it sometimes becomes difficult to keep track of everything, be aware of everything and be able
to do everything. Every installer (or installation firm) should therefore carry out a small study of their own
possibilities, skills and level of knowledge.
Draw up a list for yourself of the things you are good at (specific techniques, installation, sales, etc.).
Also draw up a list of the things at which you are less proficient.
Check whether there are items in this last list that you can improve yourself, for example, by following
a training course.
Go to evening classes that explain the new technologies in real terms.
Monitor new trends, techniques and materials through specialist magazines for the professional
installer and by regularly visiting trade fairs, both at home and abroad.
Consider joint ventures with various colleagues (audio, security, heating, integrator, programmer,
etc.). A group with different skills can achieve more than an individual.
Perhaps you are good at techniques, but your sales opportunities do not deliver the desired result.
Join forces with someone who is happy to take charge of supporting the architect, principal and other
techniques. Work together with an integrator.
There is and will be an increasing demand for specialists in the current and future residential
construction market. Invest in the necessary training. Over the years, the function of the electrical
installer has changed. Where once you could offer everything, this is now becoming much more
difficult. Make the right choices for your business.
