An Opportunity to Reduce Business Costs

The 500 companies subject to taxation on carbon emissions are generally well experienced in what to do about mitigating the cost. One of the strategies will be to pass on the tax burden to other businesses, the public sector, and the private individual. For business and public sector users this provides an incentive to reducing these consequential costs. It can also be considered as a contribution to reducing Australia's greenhouse gas emissions.

Perhaps the biggest and most easily identified cost increase will be in energy and, in particular, electricity. Some basic steps include the following:-

Air Conditioning Operation and Maintenance

Increasing the temperature set-point of your air conditioning in summer - Increasing the temperature set-point by 1°C will reduce the amount of power your air conditioner uses by up to 10 per cent, saving 200kg of carbon pollution.

The performance of Heating, Ventilation and Air Conditioning (HVAC) equipment deteriorates over time, so a well-designed maintenance program can yield significant savings.

Switching to energy efficient lighting, replacing your old air conditioner - Replacing air conditioners that are more than 10 years old, can save 20 to 40 per cent of your annual heating and cooling energy costs. That's nearly 700kg of carbon pollution saved.

Improving building insulation and reducing wasted space including lowering ceiling height are additional strategies.

Compressed Air System Maintenance

Fixing leaks in your compressed air system can improve the efficiency of the entire system by as much as 40 per cent.

By keeping leaks and pressure drops to a minimum, pressure is properly matched to actual demand, saving power and money.

Reducing your operating pressure by just 100kPa can save 8 per cent on your power bills. Every 100kPa reduction in operating pressure can save around 8 per cent on power costs.

Reduce the compressor input air temperature. A 3°C reduction in inlet temperature can reduce the amount of electricity required to run your compressor by around 1 per cent. It might be as simple as relocating the air intake to a cooler location in your plant.

Reduce Lighting Costs

Lighting accounts for 15 per cent of the total power use for a basic building and 33 per cent for a commercial facility. After installing energy efficient fixtures, there are additional steps that can be taken.

How Can TechRentals Help?

A number of instruments can assist in problem detection and measurement and virtually all are within the scope of the end user or tradesperson to operate. The time saved and the results achieved can be expected to justify the small rental cost many times over.

Electrical Energy Consumption

Power analysers and recorders can be used to measure actual power consumption down to individual machine level. Power factor problems can be determined in larger plants and these may have a direct effect on electricity charges.

Air Compressor Maintenance

Leakage detection and pressure may be the main measurements. More specialised measurements can include moisture.

Thermal Imaging Cameras

Thermal imaging cameras are a highly versatile tool that can quickly detect a number of problems, including: insulation voids, steam leaks, hot bearings, and faulty electrical installations, all of which contribute to energy wastage. Renting one for one or two days will often uncover a number of unsuspected faults.

TechRentals sales engineers are always ready to offer advice on any aspect of test and measurement instrumentation selection and use.
