Five Big Ideas From the EnergyLab Hackathon
A few weeks ago, EnergyLab ran a one-day hackathon in Sydney. Thirty people got together to brainstorm ideas and build prototypes for the future of Australia's energy system. I went along for the final pitch session and was inspired by the scale of ambition and the quality of the ideas. Some of them will take a fair bit of work to execute but hopefully the teams persevere and unleash their products on the market.

Variability: Efficiency Tweaks for Your A/C
A/C systems can be set up to use 30-50% less power if variable control technologies such as variable speed drives (VSD), variable air volume (VAV), and variable refrigerant flow (VRF) are used. These technologies allow A/C systems to operate efficiently at part-load, lowering energy use and extending lifetimes. Find out more about how these can fit into your current site with our guidelines on the relative advantages for each type.

It's been a challenging experience of continual learning. Now that I'm working at COzero this is where the real learning. It has been a challenging but rewarding experience starting my first role in the tech industry.

A Standard Work-Breakdown Structure for Data Science
In a previous post we introduced how we are approaching data science at COzero, making sure it is an integral part of our DNA as a company. However, data science processes are usually described by some rendition of elements of the scientific method or at times borrowing terms and procedures from statistics. Here we present our interpretation of that process in more detail, which we don't claim is the whole truth but a conscious effort to remove the hype to make the process sustainable from a business perspective.

Data Science in a Business Context
Much is said about the successes and failures of the new kid on the block, data science, and arguably there is much hype about it today. But being at the core of COzero's DNA, we made a conscious effort to remove the hype and use data science within our business. What does it mean for a company to do data science? Here is our answer.

What Do Changes to NABERS Building Standards Mean for Businesses?
Australia's NABERS building standards program has been in effect since 1998 and has helped building owners save more than $100 million in the last seven years alone. In July, 2017, the program was extended to cover even more commercial buildings. To commemorate this milestone, I'll review how NABERS compares to other efficiency rating programs around the world and examine whether NABERS compliance has a positive return on investment.

What Does the Power of Choice Ruling Mean for Australian Businesses?
From December 2017, all new buildings will get smart meters as part of the AEMC's Power of Choice ruling. Are we all doomed to grow extra eyeballs from the radiation from smart meters and have our homes broken into due to meter data hacks or could the extra data that smart meters provide make the grid stronger and more efficient? It will all depend on the success of the implementation but hopefully the learnings from smart meter rollouts in Victoria and Italy will make Power of Choice a tour de force for Australia's electricity market.

How Does Australia's Energy Efficiency Compare to Other Countries?
Since 2012, Australia has plummeted from 6th place in the ACEEE international energy efficiency benchmarking report to 16th. During the same period, Japan has leapt forward from 6th place to 2nd place in 2016. Both countries have substantial room for improvement and our hope is that efforts from utilities in both countries to help their customers reduce energy consumption will propel Japan and Australia up the ranks in the 2018 report.

Optimising Operational Hours to Minimise Capacity and Consumption Charges
Having an efficient operational profile makes the difference between flicking an electricity bill over to accounts payable and having a heart attack while skimming over the capacity charges. It's important to ramp equipment up sensibly so that you can maximise occupant comfort and productivity without causing consumption spikes.

When Does Submetering Make Sense?
Managing energy consumption without submetering is like trying to drive without headlights. If you manage a large site, submetering gives you granular consumption data so you can pinpoint waste, streamline your operational profile and pass on costs to tenants.

Dealing With Electricity Bill Shock Post July 1
Electricity prices have skyrocketed since July 1st but that doesn't mean you just have to groan and pay up. Take ownership of your bill - negotiate a better rate and then use the bill shock as motivation to decouple your revenue from your electricity bill. There are a myriad of ways to reduce your energy consumption whilst serving customers better. Our customers typically find they can reduce their consumption and capacity charges by 20%. That'll do a lot more for your bottom line than trying to haggle over a few cents/kWh.
