Assumptions

1. All prices are exclusive of GST.
2. Figures are approximations, based on a typical scenario. Your savings will depend on your specific situation.
1. Regular PC energy usage based on Dell Inspiron 546 (2.8GHz, 8GB RAM, Windows Vista) (www.energystar.gov)
2. Electricity costs based on 20c peak and 12c off-peak, plus 6c for 100% green power (www.truenergy.com.au)
3. Regular PC replacement cost based on basic office system plus Windows 7 licence (www.eyo.com.au)
4. Conversions between kWh and tonnes of CO2-e from "National Greenhouse Accounts (NGA) Factors", June 2009, Australian Government, Department of Climate Change, Table 39 (Full fuel cycle, Victoria, Latest estimate) , p 60
3. The following additional assumptions have been made in the calculations:
1. Energy usage includes keyboard and mouse, but not monitor. fit-PC2 also includes wireless card.
2. Building requires air-conditioning (indirect electricity usage), with a Coefficient of Performance of 2.5, to remove excess heat.
3. Replacement costs include operating system licence (Windows 7), but no extended warranties.
4. Calculations do not take into account the following additional cost-savings and benefits of the fit-PC2:
1. Reduced maintenance costs from increased reliability
2. Reduced downtime from increased reliability
3. Reduced workplace noise and decreased employee stress due to quiet, fanless operation
4. Reduction in circulating dust due to fanless operation
5. Lower embodied energy due to significantly smaller size
6. Reduced recycling costs due to less materials embodied
7. Reduced air-conditioning infrastructure and maintenance requirements
8. Reduced desktop space requirements and less cabling
5. These additional benefits of the fitPC2 are also important:
1. Improved sales, reputation and staff morale through demonstrated commitment to sustainability
2. fit-PC2 will operate in higher temperature environments (up to 70°C without a HDD or with an SSD, up to 45°C with a HDD) than a regular PC (up to 45°C)
