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.

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.

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).

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.”

The fully integrated primary school

October 19th, 2009

The Government is currently investing £45 billion in regenerating our schools and a target to re-build or significantly refurbish all secondary schools and 9,000 primary schools by 2016 is well underway.  It’s an incredible undertaking and one which will guarantee that our schools can offer a functional, fit for purpose learning environment for our children and a more cost effective, comfortable, secure and environmentally sound building.

Project Type

At a leading West Yorkshire Primary School the local Council had already completed a large-scale refurb programme that modernised the 140-year-old main school building, improving energy efficiency and security for staff and children.  A full electrical re-fit also had a critical role to play in achieving the school’s objectives.

Customer Expectations

It was essential we preserved what is a beautiful Victorian building, but at the same time moved the School into the 21st Century and made use of modern building technology.  It was agreed very early in the planning stage that the school could achieve our target of vastly improving the buildings electrical services and reducing our energy consumption by incorporating a fully integrated, controllable system.  We wanted to ensure that energy’s never wasted, while lighting and heating is of the highest standard in order to provide a pleasant environment for both pupils and staff.  The specification for the electrical services goes far beyond what is usually installed into a school, making us a striking example of what can be achieved through ground breaking electrical integration.

Customer Comment

The school is becoming closely aligned to the business world, with smart buildings that are designed to deliver services tailored to meet the needs of the occupant and reduce energy consumption.  By integrating our varied electrical systems, we now have total control over the entire school from our main reception office.  We’ve also achieved a significant reduction in overall energy consumption, an issue that was imperative in terms of both the environment and our budget.

Top Features

  1. A fully integrated Building Management System, that utilises the KNX protocol and is future-proofed for flexibility, upgrades and any changes down the line.
  2. All electrical works were completed during the Easter break without any disruption to the teaching schedule with KNX fast fit ‘plug & play’ technology.
  3. Jung Door Communication Management system with video feed from main entrance to the reception office.
  4. Installation of an energy efficient KNX lighting control system that is simple to operate, flexible and provides enhanced security out of school hours/term time.
  5. The buildings exterior security lights are all controlled by a dual control light sensor and event timer, ensuring that they are only switched on when it becomes dark, and allowing switch on time to change with the weather conditions/time of year.
  6. An integrated intruder alarm system that ensures all interior lights are switched off as soon as the alarm is set, eliminating the opportunity for lights being accidentally left on when the building is unoccupied.
  7. Fully integrated HVAC system that is set to turn on and heat or cool to pre-determined temperature one hour before staff and pupils arrive and also ensures that the air con is switched off automatically when the intruder alarm is switched on at the end of the school day.
  8. Merten System M room temperature controllers are fitted in every classroom/hallway, enabling the school to monitor the temperature of every room on an individual basis and adjust the heating to a preset optimum temperature.

Smart Building Technology plays vital role at East ...

October 19th, 2009

A care home for the elderly in Lewes, East Sussex was simply looking to improve lighting conditions for residents, but in the process revolutionised the building with some simple and creative electrical integration.

Project Type

There were two critical elements that the Integrator wanted to incorporate on this project.  Firstly, it was important for them to demonstrate how they could best make use of smart building technology in order to enhance resident care and make the home a more comfortable environment to live. The second was to make the building more energy efficient and contribute towards a reduction in running costs.

Customer Expectations

Elderly residents needed lighting to find the bathroom at night, but it was important for us that only the required lights were switched on as to avoid disturbance to others. Our initial thoughts were to install some form of basic lighting control system that would ensure lights could be switched on when and only in the rooms they were needed.  However, after discussions with the Integrator, it became clear we could do so much more by integrating other elements, such as the emergency call function, into the system.

Customer Comment

The cost of care is an issue for both the local authorities running the home and the families who pay for the care of their relatives. Creating a more energy efficient building is one simple way in which we can reduce costs, so if we can do this and improve the standard of living for our residents at the same time, then its a fantastic result.

Top Features

  1. Movement detectors in all rooms ensure that the lights come on automatically in the en-suite bathrooms if a resident gets out of bed during the night.
  2. The system also controls the extractor fan in all en-suite bathrooms, switching on with the lights and off after a pre-determined period of time.
  3. Meanwhile, to guarantee that lights are never left on unnecessarily in the larger assisted bathrooms and communal toilets, presence detectors have been fitted to switch lights on automatically when someone enters and off again when they leave.
  4. All rooms and hallways fitted with large touch sensitive plate light switches with LED backlighting so residents can easily locate them during the night.
  5. Scene setting switches in all communal hallways/lounge areas have allowed further energy savings.
  6. External lights are controlled with both a light sensor and an event timer that comes on automatically when it goes dark and switches the lights off automatically at the same time every night, further energy wastage.
  7. Being able to keep corridor lights switched off at night was another important element in making the building as energy efficient as possible.  Historically they had been left on all night, but with presence detection they are only used when occupied.
  8. Integrated nurse call system that when activated, only the lights between the specific resident’s room and reception area are lit, helping to identify where the distress call has originated and illuminating the way.
  9. Integrated fire alarm system that illuminates only those sections of the home affected in order to minimize disruption to residents.

Intelligent building control at your fingertips: ABB ...

October 19th, 2009
ABB Busch ComfortTouch Building Control Panel

The new Busch-ComfortTouch panel from ABB offers the total sophistication of intelligent building control in an easy-to-use, one touch display. Suitable for hotels, residential and commercial properties, it combines state-of-the-art control with exciting new energy efficiency and security features, providing users with full control of all living areas and building functions from a single location.

The ComfortTouch panel gives users a single point of control for a range of functions including lighting, security, temperature and humidity. An intuitive colour coding system that distinguishes different aspects of the building – yellow for light, amber for heating, blue for blinds, orange for climate control and purple for living scenarios – makes the system easier to use for those with little or no experience.

The control panel allows users to operate or dim the lights, adjust blinds, regulate the room temperature or create scenes from a combination of the functions listed. For further ease of use, all functions can be controlled remotely where there is line-of-sight between the panel and the remote control pad.

Another key feature is the panel’s energy monitoring function. The Busch-ComfortTouch panel provides access to energy consumption data, enabling property owners to monitor and reduce energy use by identifying areas for improved lighting efficiency, energy consumption and security.

The security function makes it possible to simulate presence within buildings, applying realistic living patterns even when nobody is there. The security system is designed to detect when doors or windows have been left unlocked and can even detect breakages. Once an alarm has been raised, an alert is sent to the user’s mobile phone informing them of the problem. The panel can also be linked to external monitoring systems, such as surveillance cameras, to monitor and record parts of a building directly from the touch panel.

With a built in MP3 player, The Busch-ComfortTouch makes it possible to create audio files or play films. Users can monitor the weather, look at the latest traffic reports, track up-to-date news, access their e-mails and even use the panel as an alarm clock. The panel can also be used to leave voice or written messages for other users to view.

The Busch-ComfortTouch is available in a black or cream coloured, high quality polished finish. Users can customise the screen colours to suit their own personal preferences. Once installed the touch panel will work in tandem with ABB’s KNX intelligent installation system as a source of control within a building. The number of control functions available through the ComfortTouch is up to the individual to decide when they are installing the system.
