Five Star Lighting Control at London Hotel

March 9th, 2010

Project Type

The main design goals for the hotel lighting were to use decorative lighting to enhance the unique appearance of this boutique hotel, to use energy-efficient lighting where appropriate, and to use night time façade lighting sparingly. Ease of maintenance was another primary concern. In addition, the lighting designers were constrained by a strict and pre-agreed budget, plus time was limited.

Customer Expectations

Decorative incandescent lighting was needed in public spaces, combined with energy-efficient cove lighting for ambient illumination. Discreet night time exterior building lighting was required in order to draw attention to the architectural features instead of just using ugly floodlighting and illuminating large areas of the façade. Furthermore, glass and faux alabaster panels with back lighting were required to customize the reception desk, boardrooms, and corridor areas. Lighting controls are standard issue in hotels and they’re widely accepted/used for the flexibility that they lend to the lighting design. Four-scene dimming control panels were requested for the public areas, such as the reception desk, atrium lobby, ballroom, boardrooms, restaurant and lounge area.

Customer Comment

Decorative lighting integrated with the lighting controls helped set the mood and ambiance of the public spaces. It was exactly we were looking for. The lighting controls provide the flexibility to adapt the lighting to the time of day. I love the fact that the ambiance of the restaurant is now different for breakfast, lunch, dinner, and for the evening. The atrium lobby lighting can be changed in response to the amount of available daylight. The lighting controls lend flexibility to the lounge areas and boardrooms, so that they can be adapted to their several potential uses. The most enjoyable part of the building is our restaurant. It’s very eclectic, and it has a lot of modern bright colors, a lot of different types of lighting, and a lot of different types of light fixtures. It is a kind of multi-purpose room: it’s an open area that not only serves as a restaurant, but a bar, and a lounge. Throughout the day the lighting controls really set the whole mood of the entire area.

Top Features

  • Achitectural dimming controls are used extensively in the lobbies, ballrooms, boardrooms, and restaurant where lighting flexibility is essential to decor and function in a stylish boutique hotel.
  • Decorative lighting was a priority in the design of the public spaces and in public transition and sitting areas such as the reception area and lobby, where dimming controls were used to make these spaces appear unique and inviting.
  • In the main lounge and restaurant, dimming is used for mood setting.
  • In the boardrooms and conference facilities, dimming provides the flexibility needed to accommodate presentation media.
  • Daylight is plentiful in the split level lobby and innovative light shelves with angled slats are used to control the angle of the light that enters the low glazing and to reflect more daylight up through the higher level glazing.
  • Eelectron range of hotel automation products throughout the hotel for the programming, management and configuration of cards, transponder readers/cards, Din Rail IP PoE Router KNX interface, eSuite Software and the TM11A KNX thermostat for controlling room temperature.

Ding Ding… KNX takes on all comers!

March 9th, 2010

After stumbling across a discussion thread on AV Forum that discussed the merits of various lighting/smart home control solutions, in response to a question on who’s the best in terms of cost a technical features/benefits, I thought I should look into this a little deeper.

OK, at Ivory Egg we could be viewed as a little KNX or DALI biased, so I promise to be as objective as possible and open to feedback here. At the end of the day we are independent, simply want to deliver the best solutions to our clients and I would hope this article, at the very least, will stimulate some form of debate. You can view the complete thread at AV Forums.

So, in terms of the players (at least who I perceive to be the market ‘leaders’ in this field), and again you may disagree with my selection, I have decided to look at the following solutions. This selection is based purely on the names I come across on a weekly basis:

  • KNX
    KNX is a standardised (EN 50090,ISO/IEC 14543), OSI-based network communications protocol for intelligent buildings. KNX is the successor to, and convergence of, three previous standards: the European Home Systems Protocol (EHS), BatiBUS, and the European Installation Bus (EIB or Instabus).
  • Crestron
    Crestron is the world’s leading manufacturer of advanced control and automation systems. They offer integrated solutions to control audio, video, computer, IP and environmental systems, and streamline technology to improve the quality of life for people in corporate boardrooms, conference rooms, classrooms, auditoriums, and in their homes.
  • Lutron
    Lutron Electronics Company, Inc. is a privately held corporation that designs, manufactures, and sells lighting control systems and a variety of other related products. Its probably fair to say that Lutron lead the way in lighting control systems.
  • Rako
    Rako provide state of the art digital dimming technology. Their innovative solutions meet the needs of a diverse range of applications by offering lighting systems that are simple to use, creative, easily installed and cost effective.
  • DALI
    The Digital Addressable Lighting Interface (DALI) is a digital protocol for the controlling of lighting in buildings, such as electrical ballasts and dimmers.
  • INSTEON
    INSTEON technology is a dual-band mesh topology employing AC-power lines and a radio-frequency (RF) protocol to communicate with and automate home electronic devices and appliances, which normally work independently. It is a home automation networking technology invented by SmartLabs, Inc., and was developed based on the X10 model for control and sensing applications in the home.

Not everybody active in this field, but a good starting point? Unfortunatley though, we have a bit of a problem when trying to compare these so-called competitors, as basically what we’re dealing with is a mix of different standards, manufactures and solutions that are all competing against each other. I would love to be in position to just compare like for like and publish the pros and cons of each, answer the questions in places such as AV Forum, but that would not provide a true representation of each solution (I hope I’m not stating the obvious here)…

For example, it makes sense on some projects to have a mix of KNX and DALI. As DALI is an open protocol for lighting control mainly in commercial buildings, while the growth area in KNX is for residential and LED. Take Heathrow Terminal 5, which has a KNX backbone with switches/PIRs etc and a gateway to DALI for the lighting. KNX can’t compete with DALI, as the DALI is fitted to the ballasts that control the lighting and sit in the actual light fitting. They are complimentary systems and we approach it from that point of view as we sell KNX/EIB DALI gateways at Ivory Egg.

In terms of KNX vs. some of the other systems, well Lutron is bar far the market leader in terms of pure lighting control. Rako on the other hand sell purely wireless lighting controls and they are great for DIY/retro-fit. As for INSTEON, which is again a wireless control technology, they currently have no European devices so it doesn’t really complete with KNX and is more of a competitor to the likes of Z-wave and EnOcean (which is another blog altogether). And finally  we have Crestron, who supply more AV & generic device control solutions.

It is worth pointing out that Crestron do provide a complete AV, lighting and control solution. It does it by controlling different devices from multiple manufactures and a wide range of different protocols via a central controller. From a consumer point of view Crestron is “Interface Centric” via tablet and in wall touch screens. This hides the complexity of using Lutron for lighting, X manufacturer for heating and Z for multi room audio. It is an expensive route to take, but on the positive side it is highly configurable.

KNX is standard based and developed from a consumer point of view. It is switch centric, in other words it is a compact and stylish intelligent switch on the wall that can easily control the ‘functions’ in a room (HVAC, lighting, blinds etc). KNX has 1,000s of products that are certified to work together, but this is not the case with Creston. That said most consumers wouldn’t know the difference, as most simply go on look and feel, and that is where market leaders such as Basalte and Gira score highly. Their products are innovative, look fantastic on the wall and at Ivory Egg we can supply a whole host of fittings for 13amp sockets that will coordinate with the wall switches. And to be fair, this is what the architects are demanding!

So difficult to draw conclusions really. I guess the big question I’ve not really answered is what are they main differences between Lutron and KNX? As Lutron is a central processor based with proprietary technology and KNX is a component/manufacturer open standard, does that mean the KNX open standard is the lowest common denominator (as claimed by Lutron) or does that mean you get vastly increased flexibility (as claimed by KNX)? Is Lutron only lighting control – on/off/dim or is it full integration. If KNX gives you full integration, then why would you even consider Lutron? All very valid questions…

Yes, KNX provides a holistic approach to efficient energy usage. It is not limited to lighting or heating or metering or appliances or AV or any other specific function for that matter. The KNX platform has been adopted by many highly respected major manufacturers with their vast choice of products covering all these product lines. In the longer term, this is also important to building owners, as any installation is future proofed for any changes/upgrades that could be needed. As KNX covers such a diversity of applications using one standard, it means cabling networks can be much more simplistic and single twisted pair cabling can often suffice, with multiple elements all operating together on a single network. As I’ve already mentioned briefly with DALI, a number of the KNX manufacturers have also developed ‘gateways’ to other control protocols. These simple devices are used to expand the capability of KNX control systems to provide the complete solution for a building.

KNX has also worked closely with management-level protocols such as BACnet to enable a close co-operation between these two standards when the project requires additional integration. Every KNX-compliant piece of equipment is fully tested and certified to this highly stringent standard by an independent regulatory body – It is only at this point that it can carry the KNX logo, as controlled by the international KNX Association of Brussels. Therefore there is total confidence in reliability and interoperability, whatever KNX devices are chosen. In the UK we have a growing network of integrators who have joined KNX UK to share their experiences and to help promote the standard. They can also assist consultants as well as building owners in achieving the optimum solution for their building and with KNX also accepted throughout the world (and with partnership agreements with more than 30.000 partners in more than 75 countries worldwide) from China to the United States as well as Australia and the Middle East, it truly is a worldwide standard.

Lutron on the other hand is recognised as the leading brand in terms of pure lighting control, and rightly so… It has many advantages and is easy to install, retrofitable and extremely reliable. Their systems are a proven, extensively implemented technology that offers 2-way communication, is scene capable and can dim any type of dimmable lighting. All this is backed by an industry leading company with a very long history and their systems are available in a large number of styles and finishes, all backed with a 7 year warrantee. Plus they too can integrate window/shade controls and offer relatively easy intregration with Crestron and other control systems. However, while I find it hard to criticize KNX (and again, I can hold my hands up and say yes we’re a little biased), to me there are some obvious disadvantages to Lutron. For one it only controls up to 32 lights (expandable to 64). Then there is the fact it has no dedicated processor, so it relies on an automation processor. In other words if this processor fails, then I’m afraid you have to manually override or you have no lights at all. However, the ‘biggie’  (in my experience anyway) is that expansion always seems more complicated than it needs to be and is certainly more expensive than with KNX products.

The choice of lighting control is a wide one one I’m afraid, the above is only our humble opinion.  To be honest, what you really need to do is decide what functionality you want and then see what systems can support your needs. Its important you select an installer that can advise you on the systems that you’re interested in. Price is always important, but do not make it the main point, and you need to always be thinking about upgrades/adding to the system in the future. Also think about who can you get to do changes and tweaks to the lighting control system (these things are never right first time and commercial clients and their staff especially can be very demanding)?Does the control system intergrate with other manurfacturers you may be using and don’t be afraid to ask for them to show you existing installations they’ve completed that are using the products you’re interested in. KNX is certainly the logical choice to me in terms of flexibility and meeting demand, especially if you need to integrate other systems such as heating, blinds, AV etc, but always keep an open mind and one eye on what each of these systems can deliver.

Flagship children’s centre makes energy efficiency ...

February 8th, 2010

A newly refurbished Nursery School and Children’s Centre in the North East is using the EnergyDatastream by Synetica to monitor how much power, water, and gas is being used throughout the facility, and how this usage can be made more efficient. The EnergyDatastream communicates with the school’s building automation system to display the utility usage information that its monitoring. This data is then presented in an easy to understand format, allowing for simple data analysis.

Project Type

The local council used a retro commissioning authority to complete an audit of the Centre to determine where there were inefficiencies in the buildings’ performances. They subsequently verified the design of the energy systems and found that a number of performance areas could be dramatically improved upon if the school updated its control system. Engineers are now using a remote online log-in to view the EnergyDatastream data in order verify that the new control system design is in fact providing the energy efficient results that it was planned to do.

The school is working on additional small steps to encourage efficiency, such as lowering the temperature in the building to save costs. About 100 children currently attend the nursery school and both children and staff are encouraged to help do their part by saving water and switching off lights when they are not in a room. Now that the usage can be viewed in real-time and for specific locations using the EnergyDatastream, they will be able to develop additional strategies to help reduce water, gas and power wastage.

Upgrading the building automation system with a newer KNX control system designed for energy efficiency will also allow the Nursery School control system to be synchronised with the new refurbished Children’s Drop In Centre that is currently under development. The Drop In Centre is being designed to feature fuly integrated facilities and is scheduled for completion in March 2010. The school had noticed a sharp rise in energy use first thing in the mornings and it was established that the Drop In Centre was the cause, due primarily to the older electric water heaters being turned on when the voluntary staff arrived.

Customer Expectations

As we work to a very tight budget and are conscious of the importance of installing environmental awareness into the children, we had to look at being at the forefront of building technology and management. The ability to collect, store and transmit all our data for energy management was critical in helping us to hit and continue to maintain our objectives.

Customer Comment

We had an idea where the spike was coming from, but now that the new KNX control system and the EnergyDatastream is in place, we’ve been able to verify that it was the old Drop In Centre. The increased energy use at this time of day is when people arrive and start getting ready for the parents and children. The performance of the refurbished Drop In Centre will be greatly improved in comparison to our old one.

Top Features of the Synetica EnergyDatastream

  1. 8 x Pulse Inputs: 8 digital pulse inputs for energy meters or digital status monitoring (S0 class meter inputs)
  2. 8 x Analogue CT Inputs: 8 analogue inputs for wired current transformers
  3. Modbus RTU and TCP/IP Communications: Connects to serial Modbus enabled meters to retrieve, log and forward Modbus meter readings. Optional Modbus TCP slave to allow access via the network to internal registers including time clock, digital, analogue, EnOcean and Modbus RTU meter values.
  4. EnOcean Wireless: Optional link to EnOcean wireless sensors and Synetica’s EnOcean wireless Current Transformers (CT) to rapidly install additional wireless meter points
  5. Ethernet Interface: Built in high speed 10/100 Mbit Ethernet links to the Internet or corporate Intranet
  6. GPRS/GSM: Optional GSM/GPRS communications for remote applications

Gira shines at Mermaid Cottage

February 2nd, 2010

Project Summary

More convenience, more economy, more security… Intelligent building technology from Gira has made Mermaid Cottage, a stunning period property, both beautiful and smart. Centrally controlled house technology, time-dependent temperature control, automatic light control, keyless access and much more – everything is designed uniformly in this stunning South coast home.

Project Description

The smart building technology installed at Mermaid Cottage can be divided into three parts. For conventional installation the cottage features a selection of Gira products for electricity, light, door communication, communication technology and more. In addition to this two intelligent systems are installed that enable a high degree of comfort, security, flexibility and economy: the Gira Instabus KNX/EIB system and the Gira radio bus system:

1. Conventional installation

Mermaid cottage features socket outlets, dimmers, push switches, room temperature controllers, LED illumination, antenna connections, motion detectors, door intercom systems and more by Gira.

2. Gira Instabus KNX/EIB system

Intelligent building technology is realised within Mermaid Cottage via Gira’s flexible KNX bus technology system. Devices communicate with each other and exchange information within the system. For this an Instabus control line is installed parallel to the power line. Possibilities: requirement-specific use of lighting and heating, central control of light, blinds, ventilation and household devices, programming of specific lighting scenes, multimedia or music entertainment in all rooms, automatic watering of the garden, presence simulations and more.

3. Gira radio bus system

Mermaid cottage benefitted from simply retrofitting the intelligence, installation without the usual dirt and noise. A wide spectrum of control options have been realised such as light scenes, blind and heating control and automatic lighting, without walls having to be chopped. Communication occurs via transmitters and receivers.

Gira’s instabus KNX flush-mounted actuators

February 1st, 2010

Now included in the family of Gira flush-mounted actuators are switching actuators, a universal dimming actuator and in terms of ‘recently launched’ products; a window actuator, a blind actuator and a heating actuator.

Flush-mounted actuators are used with decentral KNX/EIB installations or in KNX/EIB compound installations (DRA, flush-mounted). They are allotted space in flush-mounted boxes or in cable conduits and utilise the existing power cables. In this way cable material is saved and fire load in buildings is significantly reduced.

Existing installations can be expanded more simply to KNX/EIB with flush-mounted actuators – in addition to the existing 230 V supply – only a bus line is required for operation of the actuators.

Zero-voltage contacts can be connected to the binary inputs and they can carry out various functions independently of one another or as a ‘block’. The functions of the binary inputs are identical for all actuators, other attributes however are configured at the factory in order to make the operation possible without the need for programming.

The flush-mounted actuator is connected to the 230 V supply via a flexible cable, approx. 20 cm in length. The connection of the binary inputs and the KNX/EIB is made via a 6-wire connection cable, approx. 30 cm in length. This can be extended to a maximum of 5 m.

Two auxiliary unit inputs (or three inputs with window actuators, blind actuators and heating actuators) are for on-site operation via conventional switches or buttons, or can be freely used as binary inputs for zero-voltage contacts (with applied bus voltage).

Window actuator

The window actuator combines a blind actuator with a heating actuator. It has three binary inputs with which in delivery state the connected blind or shutter can be controlled.

Functions of inputs

Functions of switching inputs: two independent switching objects for each input present and can be enabled individually, command for rising or falling edge can be set independently (ON, OFF, CHANGE, no reaction).

Dimming: Single and double-surface operation, time between dimming and switching and dim-step size can be set, telegram repetition and stop-telegram transmission possible blind: Command can be set with rising edge (no function, UP, DOWN, CHANGE), operating concept can be configured (Step – Move – Step or Move – Step), time between step and moving mode can be set, slat adjustment time can be set.

Value transmitter and light scene auxiliary unit: Edge (push button as NO contact, push button as NC contact, switch) and value with edge can be configured, value adjustment with push button by pressing and holding button for value transmitters possible, light scene auxiliary unit with memory function and saving of the scene without previously calling up is possible.

  • Blocker for blocking individual inputs
  • Behaviour when the bus voltage returns can be configured separately for each input
  • Telegram rate limiting

Blind output

  • Behaviour after bus voltage failure and return can be set
  • Separately parameterisable movement times with movement time extension for movements into the upper end position
  • Feedback of the curtain position or slat position – Active or passive (object can be read out) cyclical feedback functions
  • Feedback can be delayed until after the return of bus voltage
  • Assignments to up to 5 different safety functions (3 wind alarms, 1 rain alarm, 1 frost alarm), or with cyclical monitoring
  • Forced setting function can be realised for each blind output
  • Solar protection function with fixed and variable curtain or slat positions can be activated
  • Inclusion in scenes possible, maximum of 8 internal scenes can be parameterised per channel
  • Memory function for light scenes

Heating output

  • Output controllable with a corrected variable (1 bit or 1 byte)
  • Status feedback (1bit or 1byte) automatically or on read request
  • Valve control (open/closed while deenergised) can be configured
  • Summer or winter operation can be selected via an object
  • Cyclical monitoring of the corrected variable; if a corrected variable telegram remains off within a monitoring period, the output switches into emergency mode and an alarm message is sent
  • The output can be locked in a forced position, and different values are possible for summer and winter operation
  • Behaviour when the bus voltage returns and fails can be configured separately for each output
  • Overload or short-circuit message via an object can be set
  • Control of valve drives with switching operation or PWM operation
  • Protective function for locked valve

Technical data

  • Rated voltage: AC 230 V/50 Hz
  • Connected load of blind output: switching current AC1: 3 A, motors: 600 VA
  • Connected load of heating output: contact type: Triac, switching current 5 to 25 mA, drives per output: max. 2
  • Number of inputs: 3
  • Protection type: IP 20
  • Temperature range: – 5 °C to + 45 °C
  • Dimensions: 51 × 48 × 28 mm (L × B × H)
  • Load line connection: with enclosed spring plug-in terminal
  • Installation: flush-mounted wall box (Gira recommend the electronics box from Kaiser)

Installation

The actuators are installed flush-mounted in a wall box (electronics box from Kaiser recommended). Sufficient insulation must be provided between the 230 V cable and the bus or auxiliary units. The minimal distance between bus/auxiliary unit wires and 230 V wires is 4 mm.

Heating actuator

The heating actuator is used for switching electrothermic valve drives for heating systems. It has two binary inputs to which zero-voltage contacts can be connected for monitoring of a window contact for example.

Functions of inputs

Functions of switching inputs: two independent switching objects for each input present and can be enabled individually, command for rising or falling edge can be set independently (ON, OFF, CHANGE, no reaction).

Dimming: Single and double-surface operation, time between dimming and switching and dim-step size can be set, telegram repetition and stop-telegram transmission possible blind: Command can be set with rising edge (no function, UP, DOWN, CHANGE), operating concept can be configured (Step – Move – Step or Move – Step), time between step and moving mode can be set, slat adjustment time can be set.

Value transmitter and light scene auxiliary unit: Edge (push button as NO contact, push button as NC contact, switch) and value with edge can be configured, value adjustment with push button by pressing and holding button for value transmitters possible, light scene auxiliary unit with memory function and saving of the scene without previously calling up is possible.

  • Blocker for blocking individual inputs
  • Behaviour when the bus voltage returns can be configured separately for each input

Introducing the IntesisBox®: Making automated ...

January 22nd, 2010

IntesisBox® is a small and robust device that functions as an intelligent gateway and is capable of intercommunication with KNX, BACnet, Modbus, LON, DMX, M-Bus and many other proprietary systems (BMS, HVAC, Lighting, Fire, Intrusion, Energy Management etc). Microcontrolled and easy to install via DIN rail mounting, it features RS232, RS485, Ethernet and Konnex TP1 (EIB) interfaces that are dessigned specifically to offer a range of integrations in a robust and small device with null maintenance.

With this autonomous device it is possible to interconnect directly the internal system (building automation, industrial automation, BACnet, ModBus, Konnex…) to the external system (fire system, access control system, security system, HVAC, cold/warm generation, energy generation & measurement, lighting, hotel management, home automation…). A console RS232 port is also available to connect a laptop PC for programming and monitoring the device. IntesisBox® also offers the possibility to be connected to Ethernet/LAN/WAN networks expanding thus its possibilities with connection to ethernet/IP based protocol systems, remote monitoring, networks interconnection, web server, internet/e-mail alarm sending, SNMP…

Inside its internal structure, the IntesisBox® incorporates a high performance and reliability microcontroller with flash (non volatile) memory where the operating system and integration code (firmware) are saved. This internal structure, along with a watchdog system, ensures a suitable operation of the device every time, even when faced with power irregularities such as micro-cuts or longer power failures. It has no mechanical mobile components (fans, hard discs…), therefore reducing potential malfunctions and maintenance to almost zero, making this ideal device for industrial environments. It allows (depending on the model) the generation and register of datalogs associated to internal variables, useful for example to register historical data for temperature, relative humidity, etc. Thanks to an internal interchangeable lithium battery (with approx. 10 years life time), the internal historical data is stored in case of power failure. The firmware can be also updated via the console port.

IntesisBox® allows DIN rail mounting for easy installation inside an industrial cabinet and allows a wide range of input supply voltage, from 9 to 30VDC and also 24VAC, with a low power consumption of 1.4 watts. The operating temperature range is from -40°C to +70°C and the relative humidity from 5% to 95% (non condensing). It is not necessary to have any external RS232/RS485 converter, because IntesisBox® has RS485 port and can be directly connected to a RS485 bus. IntesisBox® can be also equipped with a Konnex TP1 (KNX/EIB) optocoupled port allowing to be directly connected to any KNX/EIB bus. All available IntesisBox® hardware versions are compliant with RoHS directive (2002/95/CE).

Along with the device, it also comes supplied (free of charge) with the LinkBox software, the software tool that’s needed for configuring and monitoring the IntesisBox®. LinkBox software runs on MS Windows® operating systems and uses a serial port to communicate to the IntesisBox®. It is possible to use LinkBox Software off-line (not connected to IntesisBox®) to configure the IntesisBox® more comfortably in the office and later download the configuration to the device using the serial connection in the field. Also supplied (again, free of charge) is a console cable that’s needed in order to configure the device.  This is a standard DB9 male to DB9 female cable.  Intesis can also supplied (on demand) an external plug-in power supply (european plug) 230VAC/12VDC 300mA to power the IntesisBox® if required.

The IntesisBox® is available to order now from KNXshop.co.uk in the Communication > Gateways/Convertors section.

Omnio RATIO Room Temperature Sensor RTF103

January 3rd, 2010

The innovative Ratio®-room temperature sensor RTF103 by Omnio is an effective battery and maintenance free radio bus system for building automation.

Conventional electrical installations for lighting, shading, heating and security have reached their limits… As soon as the requirements exceed basic installation principles, installations using conventional technology become complex and expensive. The battery-free radio bus system Ratio® with EnOcean technology facilitates electrical installations, allows for a number of useful functions, increases comfort and security. It is environment-friendly and extremely economical.

The power generation is effected by transmission of roomlight into electrical energy from a solargenerator. It conduces to the measuring of the rooms temperature and the transmission by radio to the radio senders and actuators/gateways. By its very flat construction it can be installed on walls and even on glass. Short roomlight for the power generation means the temperature sensor can also be run with a battery.

The Ratio® switch actuators/receivers are activated by radio signals from the Ratio® radio senders. Each sender can actuate an indefinite number of actuators/receivers. The Ratio® radio senders have a fixed address and are programmed into Ratio® receivers (actuators). The Ratio® switch actuators activate various functions such as light bulbs, blinds, gates, doors, control valves etc.

Product & Function Description

The battery-free Ratio® temperature radio sensor is mounted on a wall and regulates temperature and air conditioning. It is used in combination with the receiver UPT and REGH or different gateways to connect to superordinate regulating systems. At each value change or in a 15 minutes interval, a radio signal (EnOcean standard) is sent that is received and analyzed by all Ratio® radio bus receivers. The Ratio® room temperature radio sensor is mounted to glass using adhesive or on walls, etc. using adhesive or screws.

Primary Functions

With the Ratio® room temperature radio sensor, the following signals are sent:

  • Measuring and transmitting actual values

KNX intelligent building technology can save energy by ...

November 30th, 2009

UMPNVB82SBGBIndustrial sites consume huge amounts of energy with non dwellings thought to be responsible for around 20% of the UK’s total energy usage. New building regulations implemented in April 2006 have gone some to way to encouraging building owners who are refurbishing to install energy efficient technology. However, there are still greater savings to be made, but surprisingly little awareness of how to achieve them. Managers and Engineers in industrial spaces are now turning away from traditional building management systems and instead looking towards intelligent building control technologies to provide the solution to energy management challenges.

But what is an ‘intelligent building’?

Today it is widely accepted as a space where all elements lighting, heating, security, access control, ventilation are able to respond in real time to the users’ needs and building occupancy patterns. The potential benefits and return on investment from an integrated building are highly tangible lower energy costs, security and enhanced facilities management. To achieve this level of ‘intelligence’ an international building control standard called KNX has been developed. Agreed by the leading manufacturers in Europe, it allows the integration of a range of products from a range of manufacturers using a simple software tool, essentially allowing them to ‘talk’ to one another and work together. The system has been designed for ease of installation with just a simple twin-core ‘highway’ cable needed (installed in addition to the mains cabling); none of the layers of cables associated with conventionally cabled systems.

Significant energy savings provide building managers and owners with a highly cost-effective way of ensuring energy is conserved. Once installed, it allows users to automatically carry out energy management and building control tasks such as the control, monitoring and optimisation of building services and load management. Using features such as room temperature management and zoned temperature control which allows separate heating settings for different areas of the building, KNX delivers a reduction in a building’s energy consumption of up to 40%.

One of the key benefits of KNX is its ability to deliver significant energy savings through lighting control. A lighting control system can be simply configured so that lights are only ‘on’ when someone is present in a room, or in a zone of a large industrial space. Russell Downing, specification manager at Siemens, explains:

“A KNX system can also monitor natural daylight levels to dim or turn the lights off when enough ambient light is present. In large industrial spaces where there may be several thousand luminaires turned on 24/7, the ability to automatically make use of natural daylight while still providing the level of light needed results in substantial energy savings. By employing these simple measures, effective use of lighting control alone can result in energy savings of up to 30-40%.”

Breaking down the barriers Mr Downing believes that KNX is not comparable to many other control systems:

“Many conventional control systems stop short of delivering the full functionality of an ‘intelligent building’: A significant human element is required for optimal effective operation even if control systems are correctly specified and installed.Understanding the concept of KNX is vital, in order to appreciate the true benefit of the available functionality and the impacts of being able to control all aspects of a building from a central point.”

According to Siemens, it does not cost the earth to integrate an Intelligent Building Control system. With consideration paid to the ever rising cost of energy prices, investment in an open control standard like KNX is a reasonable one. As Russell Downing says,

“This is all about future proofing a building. If all buildings had KNX installed as standard,the UK would be well on the way to achieving its energy reduction targets and businesses would benefit from saving money on the bottom line.The concept of an energy efficient building is not only desirable, but for regulators, purchasers and industrial managers it is also essential.”
