Things that you take for granted

Stuart Woolley Blog, Technical

Whilst working on modelling situations in the real world, or thinking about to how tackle a specific problem, it’s often surprising how many things I take for granted. Sometimes it’s worthwhile to consider how seemingly obvious, or ‘given’ information, is actually derived. The derivation process itself can often shed light and offer further intuition into much harder and/or complex problems. …

The Fourier transform is one of the most used and widespread applications of mathematics in electronic engineering, decomposing a signal into its constituent sine waves. It has applications in an enormous number of areas in everything from understanding electrical oscillations in alternating current to the modulation of electromagnetic waves. Engineering just wouldn’t be the same without it. But, don’t worry, …

Approximating Pi

Stuart Woolley Blog, Technical

Imagine you’re stranded on a desert island and you really need to find a good approximation of π for some super machine that you’re building to make your escape. Perhaps it’s AC powered from a tidal source or wind generator and there are a couple of phase angle calculations you need to make for the flux capacitor to power up? …

Energy Usage Related Signals

Stuart Woolley Blog, Technical

The power spectrum of a signal is a fascinating way of digging deeper into understanding complex systems. If you recall your basic physics, a power spectrum shows how the power of a signal is distributed over its frequency range. I have a long standing interest in chaotic systems and fractals and came across a fascinating paper from 1975 by Voss …

Buildings and their energy performance – LEED and BREEAM

Ronan Moriarty Blog, Energy

There are many different methods to assess their energy performance, two of the more popular ones are LEED and BREEAM. Leadership in Energy and Environmental Design (LEED) was first developed in North America about 20 years ago, and is now widely used around the world and it is very practical and user friendly as well as being available online. Building …

ISO 50001

Happy Birthday to you Mr. ISO 50001

Helene Ljubanic Blog, Energy

A very happy 5th birthday to the ISO 50001 standard! It is not surprising to see that more and more organisations are turning to the ISO 50001 standard to improve their energy efficiency. To date there are more than 7,000 sites worldwide that have achieved the certification. But what is ISO 50001*? ISO 50001 is a voluntary International Standard developed …

Battery Power is going salty

Ronan Moriarty Blog, Energy

One of the biggest problems faced by renewables is the unreliability of them – when the sun’s not shining, you can’t use it to heat anything. One way to solve this problem on a small scale is to have the turbines charge a battery, and then when there are periods of no wind the battery can take up the slack …

HVAC Energy Efficiency

HVAC Efficiency Tips for your Business

Catherine Devaney Blog, Energy

On average, HVAC systems account for 40% – 60% of a building’s energy consumption. Increasing HVAC efficiency in buildings is critical to reduce detrimental global energy usage impacts, as well as saving your company money by reducing usage costs. So, what exactly is HVAC Efficiency? In basic terms, it means making sure your HVAC equipment is heating and cooling your …
