There are two approaches to managing energy more efficiently: passive energy efficiency and active energy efficiency. Passive homes, for instance, use insulation, heat recovery, and solar heating to achieve energy self sufficiency. However, the passive approach alone is not enough. Energy efficiency is by nature a long-term endeavour of active demand management. The ultimate goal is for buildings to produce more energy than they consume, a trend that is reflected in recent regulations.
Whether buildings are older and less energy-efficient or state-of-the-art positive energy buildings, metering and monitoring are the basic building blocks for efficient energy management. Effective metering and monitoring give owners and operators crucial information about how their buildings are performing so that substantial, almost-immediate improvements can be implemented.
For example, an effective metering and monitoring system has the capacity to get tenants, property managers, and owners involved in energy-efficiency measures. The ability to identify and quantify energy usage is often sufficient to bring about energy-saving changes in practices and behaviours, such as reducing waste and avoiding peak utility rates. In a single operator, owner-occupied office building, for example, the introduction of effective metering and monitoring systems brings immediate energy savings of 10% and can also help reduce building operating costs.

Energy Saving Strategies
Lighting is considered a “quick hit” by many building owners and managers looking to save energy and reduce costs. Improving lighting is not just about energy efficient lamps, but also about the right amount of light, the right lamps, controlling lighting, and ensuring systems are commissioned and maintained correctly. Velocity Electrical is your specialist.
Reducing your energy consumption through tailored solutions.
Energy Audits - Energy audits are comprehensive evaluations of the actual performance of a facility’s energy, using systems and equipment, compared against the designed performance level or the industry best practice. The difference between observed performance and “best practice” is the potential for energy and cost savings.
There is not a single person that can afford to ignore the potential for saving energy - particularly electrical energy. There is no option; if individuals, organisations and management do not act now, they will be forced to act with no control over timescales or requirements. The fact is that there is available expertise and easily affordable technology investments that can be made with a fast payback period. In many cases, however, there is a lack of understanding about how energy can be managed and how energy efﬁciency can be achieved.
Managing energy is the key to maximising its usefulness and economising on its waste. It is not just by reducing electricity consumption that savings can be made. The key to controlling energy is the use of technology.
In commerce, it is estimated that as much as 90% of all building controls currently in use, are deﬁcient when it comes to energy efﬁciency. In industry, some 90% or more of all AC electric motors are totally uncontrolled. In the home, simple lighting controls, energy saving lamps and better heating controls can all be installed quickly, simply and cheaply. In industry and commerce it is not just the equipment that is powered by electricity that presents opportunities for better management. Power quality issues, such as improving a site’s power factor can make substantial savings.

Power Factor Correction
Power Factor relates to power quality or efficiency in a power supply system. Power Factor (PF) correction helps businesses maximise energy use by reducing waste. High on the list of suspects are air conditioning compressor motors, machines running on idle mode and dated fluorescent lighting systems. This causes electrical inefficiencies to the incoming power supply system. A low factor can be improved by having a power factor correction unit installed which can improve the hidden running costs of motors and other inductive loads.

HVAC is often a major component of the energy costs in a building. The efficiency of HVAC is dependent on both the efficiency of the equipment and the efficiency of the system - how it is designed and operated. Choosing the lowest cost system will often be a mistake when lifecycle costs are taken into account. However, even high-efficiency equipment can underperform if not operated optimally.
Motor Control Electric motors make up the single largest end use of electricity in many developed countries. In industrial applications, electric motors account for roughly 60% of electricity consumption; in the process industries, electric motors can account for more than 70% of electricity use. The cost of running a motor can be as much as ten times to the purchasing cost of a motor. Therefore operation of motors represents a huge potential for energy savings.

Velocity Electrical can assist in a variety of key success factors to optimize the efficiency of an HVAC system. We can investigate how the efficiency of your HVAC system is measured, and how the overall capacity of the system can be optimised.
Many motors only have two settings: on and off. They operate at constant speed. If a motor turning at constant speed is driving a device or process that requires less output, adjustments are required to achieve the desired output level. This adjustment is often achieved by letting the motor run at full speed, while using downstream devices to block part of the output. This is like driving your car by having one foot fully depressing the accelerator pedal, and the other on the brake to constantly control the speed. It sounds absurd, but this is still one of the most common control methods. An estimated 60% of motors are not speed controlled. Velocity Electrical can help you control motor speed efficiently and with minimal physical stress on equipment. In addition, we can implement other advantages such as controlled starting and regulated torque.
