Commercial Building Disclosure (CBD)
Commercial Building Disclosure (CBD) is a national program designed to improve the energy efficiency of Australia’s large office buildings.
The disclosure requirements under the CBD program will commence on 1 November 2010.
The CBD program will ensure that credible and meaningful energy efficiency information is available to prospective purchasers and lessees of large commercial office space. Owners and lessors of commercial office space with a net lettable area of 2,000m² or more will be required to disclose energy efficiency information to prospective purchasers and tenants when the space is to be sold, leased or subleased.
Transitional Provisions
The legislation contains transitional provisions that will apply for the first twelve months of the program (i.e. from 1 November 2010 to 30 October 2011). During this period, a valid National Australian Built Environment Rating System (NABERS) Energy base or whole building rating, must be disclosed. After the transition period, a full Building Energy Efficiency Certificate (BEEC) is required to be disclosed.
Renewable energy the way of the future
Alternative and renewable energy sources continue to be hot dicussion topics throughout the world. Both solar and wind power are renewable energy sources that continue to attract considerable attention.
Solar Power
Located in Nevada, USA, construction of the largest solar thermal power plant to be built in the last 15 years, is nearly complete.
The 64 Megawatt Nevada Solar One power plant will generate enough power to meet the electricity needs of about 40,000 households and follows in the steps of the 354 Megawatt solar thermal power plants located in California’s Mojave Desert.
While California’s solar plants have generated billions of kilowatt hours of electricity during the past two decades, the Nevada Solar One plant will use new technologies to capture even more energy from the sun.
Wind Power
At the end of 2006, the total installed wind power capacity throughout the world was 74,223 megawatts which accounts for less than 1% of world-wide electricity use. This generation figure is up from 59,091 MW in 2005.
The countries with the highest total installed capacity are Germany , Spain, USA, India and Denmark. These installations account for approximately 20% of electricity use in Denmark, 9% in Spain, and 7% in Germany.
Generally it can be difficult to site wind turbines in many areas for aesthetic or environmental reasons, and it is also often difficult to integrate wind power into existing electricity grids in some cases.
Notwithstanding these issues, the wind energy sector has become an important player in the energy market, with the total value of new generating equipment installed in 2006 reaching approximately US$23 billion.
It is expected that the 2007 analysis will show a continuing and substantial increase over previous years.
