How do you save energy?


There are three different approaches nowadays:

    ⁃ You select the energy saving measures intuitively. It is hardly measured if not just to confirm your own intuition.

    ⁃ You start with a bird’s eye vision (top down) to measure consumption.

    ⁃ The Energy Management Standard ISO 50'001 is introduced.

    The first approach is the most chosen, but leads to various “island projects”, without taking the context into account. This usually does not produce optimal results and sometimes you regret the decisions afterwards because it makes further optimization more complicated.

    The last approach is correct, but it is mostly only used by the largest companies. 30 organizations in Switzerland are now ISO 50'001: 2011 accredited.

    The second approach is suitable for large and small organizations and is (only today) relatively easy to implement. You can get in cheaply and start with the largest energy consumers by first looking at the total consumption (top down). After obtaining success with the large consumers, you can proceed with the analysis of the remaining consumers.

Find the low hanging fruit​


Recording consumption in real time (e.g. every 15 minutes) has unexpected advantages. You have so much information and insight into what is really happening that you become aware of energy wastes that normally remain invisible. This also includes the situations of forgotten consumers, the neglected of maintenance and wrong settings (e.g. timers) or in the organization, which can be optimized with little or no investments. 

It is precisely this "low hanging fruit" that you want to find, since you can use it to amortize your investments quickly, if you even need to spend money for these optimisations. In this way, you not only find enthusiasm from the management, but you also have an early cash flow that you can reinvest in other energy-saving measures.

Start simple​


As mentioned in the above-mentioned text "Is energy transparency expensive?", The "low hanging fruit" can be found with little effort. 

Getting started in the Energy Management System can be very cheap by starting “Top Down” and not analyzing all systems, but initially only the largest energy guzzlers.


This limits the measurement effort as compared to the obtained savings and quickly generates a cash flow. This not only enables further energy saving measures, but also sets free resources for a more detailed measurement concept. In this way, more and more systems will be improved by the energy transition of your company. You create a cycle that feeds itself and supports perfectly the implementation of your target agreement.

Your advantages

Automatic data acquisition of consumption has been around for many years and it is becoming cheaper and more powerful. It enables consumption to be recorded not only by the entire company, but also by individual consumers “behind” the main meter in real time and to collect and analyze it on a computer. The analysis functionalities of Energy Management Systems (EMS) are becoming more and more impressive and some are even assisted by artificial intelligence (AI). So you get more and more insight into your own "Big Data". Recording in real time allows you to learn a lot about the time behaviour and the functioning of the systems and determines the influence of large and small consumers on total energy costs. Also, you often discover optimizations that are not in the area of ​​energy saving, e.g. productivity, comfort, security, ... This extends the cash flow from the energy savings with the benefits of improvements in the other areas.Take for example: 

    ⁃ Less energy costs means more profit and (with constant Price to Earnings ratio) an increase in the value of the company.

    ⁃ Greater convenience in day-to-day management.

    ⁃ Satisfied and proud employees. 

Start even cheaper

Birdseye makes getting started even cheaper by renting (rather than purchasing) a few data points (in the EMS cloud application) and hardware for a few weeks / months.

Birdseye can then evaluate the measured data and support your company, to have more success in the energy transition. 

Afterwards you can always decide to purchase an annual subscription from your favourite Energy Management System and to purchase the measuring devices and data loggers on the hardware market. This makes the transition from beginner to expert seamless.
