Fire Protection in existing buildings
You can sometimes get a better understanding of issues in our industry by looking at how others address the same problems and the fundamental risks involved. Not always do the simple application of codes meet our real needs.

All these electrical risk issues come together in a building and in close proximity to its occupants. It is to the benefit of those people that the electrical design actively mitigates unwanted harmonic frequencies and EMI in and produced by the electrical system………… We live in an electromagnetic environment which our bodies have evolved to live with, to a limit. Beyond those limits the electrical system can become a nuisance, dangerous or health threatening.

Nanometre “fuses” for high performance batteries.
Minuscule tubes coated with a chemical fuel can act as a power source with 100 times more electrical power by weight than conventional batteries.
As these nano-scale “fuses” burn, they drive an electrical current along their length at staggering speeds.

More efficient solar cells
A new technique developed by a University of Toronto engineering professor and his research group could lead to significantly more efficient solar cells. A recent paper published by the group describes a new technique to improve efficiency in colloidal quantum dot photovoltaics, a technology that already promises inexpensive, more efficient solar cell technology.

Electricity market for tenants
Unlike the rest of us many tenants in large office buildings and shopping centres are only able to buy electricity from their landlord albeit at the most favourable tariff. This is now being reviewed by the Queensland government

Electricity on-supply in Queensland
The on-supply of electricity involves the owner, occupier or user of a premises buying from a retailer and then supplying and selling it to the occupants of a premises.
On-supply is not heavily regulated. For example, a person who receives the electricity is not viewed as a customer as defined in the Electricity Act and this means that receivers lack access to customer protections and access to the Energy and Water Ombudsman.
By calling for submissions from interested stakeholders, this discussion paper aims to gain a better understanding of the issues surrounding on-supply of electricity in Queensland.
