Solar Powered Copper Mining Australia

Sandfire a copper mining operation in Australia is leading the way with a new $40 million solar farm to power its distant mining operations, far from the grid.

Presently the DeGrussa Copper-Gold Mine, located 900km north-east of Perth in Western Australia, uses diesel for power generation, and the company reports outstanding energy and environmental savings will be achieved using the solar farm to generate power, Carbon dioxide emissions are estimated to be reduced by 12,000 tonnes a year.

The project will comprise 34,080 solar panels covering 20 hectares , combined with 6MW of short-term battery storage to provide peak power for the mining operation by being integrated with existing base-load 19MW diesel-fired power station.

Productivity where are thou

Improving productivity is one of those subjective areas that rarely attracts much attention, studies show that comfort conditions are critical, is it a key part of the goals for a green building, for productively.

Where the people feel their work environment is too hot, too cold, too dry or too wet, productivity drops, and in Hong Kong it is a real issue since most buildings have no winter heating.

A recent survey, by a software company, supports the notion that your workers are dissatisfaction with environmental conditions, and that in turn impacts the productivity of your business.

More detailed than other studies, this survey covers different genders, and different seasons. One finding is stands out immediately the report states 10% of staff are totally dissatisfied.

Whilst this will not be surprising to Building Services engineers who are taught that engineering systems can only satisfy 80% of the occupants in room, It is time to challenge those empirical tests, when we have better options, underfloor distribution, and smart phone computers in our pockets.

However, visit any modern building and you will still find the room sensors in odd positions, often outside the occupied zone, this strategy only provides the general/average room condition (often near the ceiling) not the conditions where the people are working.

Hotel function rooms have sensors located 6m above the occupants, so the HVAC system is working hard to main the conditions for the ceiling zone not the people zone. Also lighting fittings, hand dryers, etc. which act as localized heaters, installed beneath sensors influencing the room conditions.

Efficiency Vs Death

Everyday in China approx. 4,000 people die as a result of air pollution [1,2,3] – that is staggering!

The report suggests the link with pollution discharged from Coal fired power plants the predominant means for power generation, although the number of vehicles on the roads is also growing rapidly that in turn creates increased roadside pollution.

Improving energy efficiency reduces energy consumption, energy costs, and will save lives! It is a no brainer, yet many firms will not consider improving energy efficiency.
