KNX Improves Building Operational Efficiency

Energy-efficiency of building operations is now a deciding factor in the consenting process as well as an important ‘business responsibility’ to minimize your company’s carbon footprint in light of climate change.

Energy efficiency is an extremely important factor during planning stages through to construction/commissioning. You can have a building with all the efficiency hallmarks and equipment installed but if it isn’t programmed or the automation architecture isn’t appropriate it will have low operational efficiency. You need a competent design, installer and commissioner as missing one of those three aspects in your build process is detrimental to the costs and efficiency of your commercial building.

There are now essential requirements for architects to construct buildings with energy-efficient architectural design, an insulated exterior and modern electrical engineering which maintains a high level of operational efficiency.

The consumption of energy for integral building operations such as lighting, heating, cooling etc. depend on both the overall building design and end-user/occupant behaviour.

KNX systems are able to regulate and control the generated heating and cooling capacity in line with demand — and also manage lighting installations using occupancy sensors and timer programs (so they operate more efficiently).

Ester Electrical can integrate your KNX system to tie in with renewable energies such as solar, wind, hydro and geothermal on-site or off-site solar/wind farms and o other franchises in other areas. KNX can work to your business’ or building’s carbon offset by the Intelligent capture of consumption data (Smart Metering) and intelligent networks (Smart Grid) for offsite generation/savings

KNX Improves Business Operational Efficiency KNX and Manages Energy Consumption

All successful businesses drive to maximize efficiency in daily operations, keeping the costs in check and pushing productivity up.

Business operational efficiency has a lot to do with managing the resources of the entire facility (e.g. staff work-flows, electricity, time, money, etc.) in a way that reduces waste and maximizes output.

KNX automation systems in commercial or industrial buildings can connect a multitude of devices inside the same facility to exchange information that allows for maximum workplace efficiency.

  • Pre-heating rooms so staff aren’t cold or hot when working, or playing around with the temperature controls
  • Automated blind/louvre control for curtains, blinds, saving staff disruptions, allowing them to focus on their task at hand
  • Ensuring correct lighting control and light output is achieved based on time of day and exterior light levels, low light levels in high focused manufacturing or intricate work environments can be challenging and slow down workers productivity

An industrial site or a business complex is often quite large, therefore KNX makes a huge difference when it comes to bringing together every room, every employee and the automated operations of integral building functions.

Ester Electrical ‘s KNX Automation package makes it far easier for, employees (or building occupants) to achieve optimal performance on a daily basis.

KNX Energy Management – Cost Saving Benefits

A KNX automation system doesn’t just save time, it also provides financial savings through efficient energy management, usage and consumption for your business.

KNX systems provide effective energy management through:

  • Peak Demand Monitoring
  • Smart Metering
  • Current Detection
  • Network Monitoring
  • Energy Pulse Counting
  • Load Shedding
  • Smart Load Balancing
  • Power Factor Correction
  • Data Logging and Visualisation

KNX systems for commercial and industrial buildings also reduce the costs required for the installation and maintenance of such things such as traditional switches, wiring, banners and other things — which when purchased and used manually, can amount to substantial financial burdens for the business.

Often the cost of investment from traditional 230v switching to smart wiring and automated light control is with a 15% cost difference across the entire project.

In the event of lights, HVAC and other building mechanisms failing and requiring manual labour to be fixed, this only adds to the costs. When everything is controlled by KNX automation, all of these maintenance costs are totally removed and only arise when the time comes to completely replace all lights, heaters, air conditioners, etc. the switching is completed remotely on low voltage meaning switches and sensors go through less wear and tear during their operational life and are also safer due to the only very low voltage present at these controls.

For commercial and industrial businesses, KNX automation can be extremely beneficial in terms of energy management and energy costs.

KNX is Future – Proof Technology

For a system to be futureproof, it is surely a given that it is built on a ubiquitous and harmonised platform that assures there will be continuity of supply.

There are many many now unsupported “dated” automation packages out there. They no longer have customer support, the contractor no longer uses or installs the product and there are no replacement parts in case of an equipment failure.

Clients as the end-user – and indeed integrators charged with maintaining the system – cannot be hostage to the commercial whims of one supplier. It follows that proprietary systems – even when they are thinly disguised as ‘standards’ – are not future proof. With KNX, there is an assurance that this will not happen. Manufacturers of KNX compatible devices, and there are over 400 of them with over 8000 KNX accredited components, are attracted by the global marketplace the open communications protocol creates. In return, they must ensure that every KNX product they submit for certification is backwards compatible. Essentially a decentralised supply network which ensures continuity of products and components even in the event if one or two manufacturers discontinue manufacturing.

Most of the other “quasi-standards” out there can be integrated into a KNX system.

KNX Systems are Flexible, Robust and Simplistic in Design

Changes and upgrades to installations must be simple. We live in an age where customers expect ‘plug and play’, not ‘rip and replace’. The KNX approach of distributing intelligence and addressing field-level devices via robust, inexpensive TP cable is logical, it allows for cheap provisional wiring to ensure your system has easy scalability for future additions or expansions for the currently installed system.

So while, say, DALI offers on the face of it a good degree of flexibility at the control panel end, significant changes to the lighting schematic are likely to involve costly and disruptive building and remedial work.

With a KNX system where you can just drop down from the nearest node on a bus cable. In practice, a popular solution is to couple DALI lighting zones within a building-wide KNX system using readily-available and KNX-certified gateway devices.

KNX Systems Can Be Easily Scaled and Upgraded as Needed

At 9600bps, the bus can support over 50 telegrams (instructions to field level devices or feedback from them) per second which is more than sufficient because intelligence is distributed on a KNX network.

A KNX installation is further divided into lines and areas, each independent from any others and each with its own capacity of 50 telegrams per second. It is clear that cable bandwidth is not an issue.

While cable remains the backbone of most KNX systems there is, of course, a secure IP connectivity. Enabling remote control applications here running cables is extremely expensive, impossible or the devices are installed retrospectively after construction is completed.

This all leads to the inevitable conclusion that KNX is unquestionably the best solution for futureproofing intelligent buildings control.The customer has a building that will keep working for them; the integrator has a customer that will keep coming back for more because the price and hassle barriers of continuous improvement are, relatively speaking, negligible.

The key promises implicit in a KNX system are that all the devices they install will work together as intended,any one device can be replaced or upgraded, without compromising the whole system, expanding and reconfiguring the systems to accommodate the need to change the way a building is laid out and used will always be possible any new KNX software developments will be backwards compatible.

 A device that was addressed by the KNX configuration software (ETS) in, say 2000, can be managed just as easily with, say a 2025 software version and beyond.
