Common electricity loads in commercial buildings — a new report from the San Luis Obispo electrical contractors

-Business runs on electricity. It’s needed to keep the doors open, produce merchandise, deliver goods and services, and keep customers supplied and content. Energy industry experts claim that California businesses pay some of the highest electricity rates in the nation, making energy use a bottom-line cost savings target. One of the most effective ways to save money on electrical use is to know where the most common electricity loads are in a business, and then take energy-efficient measures to reduce those loads without compromising the quality of goods and services. The Electricraft, Inc. team has prepared this report to help business owners see where their operations are using the most electricity and to provide some recommendations to help reduce the energy bill without degrading production and service.

Common electricity loads

The most common electricity loads come from lighting, plug loads, and heating, cooling, and ventilation. In some cases, certain manufacturing and specialized equipment are also heavy energy users. An inspection and evaluation of equipment in these circumstances may also lead to more efficient energy use.

  • Lighting: Illumination accounts for a significant chunk of energy consumption in commercial buildings. It’s not just the ubiquity of lighting in these spaces; it’s also the sheer quantity of bulbs needed to brighten up vast areas. Unlike homes, where we often develop habits of switching off lights, commercial spaces may keep their lights on for security reasons or operational requirements.
  • Plug Loads: In our tech-savvy world, we’re plugging in more electronics than ever before. Think of computers, monitors, printers, servers, and even the coffee machine in your office kitchen. The proliferation of these devices adds to the building’s energy consumption. Healthcare facilities, with their intensive monitoring tools and medical devices, are also high on the plug-load scale.
  • HVAC Cooling: Maintaining a comfortable climate for work requires air conditioning in many parts of the world. With global temperatures on the rise, the demand for cooling systems is only increasing. HVAC systems, including air conditioning, can account for up to a staggering 45% of a building’s energy consumption. Commercial buildings need powerful systems to effectively regulate the temperature of large areas.
  • HVAC Heating: Heating is just as critical as cooling in commercial buildings. Boilers, heat pumps, and gas water heaters are commonly used heating systems. The challenge here is that the heating requirements fluctuate throughout the day based on occupancy, making standardized heating practices highly inefficient.
  • HVAC Ventilation: Proper ventilation is vital in shared indoor spaces. However, the energy needed to ensure efficient ventilation is often underestimated. While it might not be as visible as lighting or HVAC systems, ventilation systems can be energy-intensive. Mechanical ventilation, including fans and air circulation systems, is necessary in some cases. Bringing in fresh air from the exterior and maintaining indoor temperatures requires significant energy inputs.

Increasing energy efficiency

The electrical contractors from San Luis Obispo’s Electricraft advise that the first step to increasing energy efficiency is a thorough inspection of electrical systems. Electrical inspections for commercial buildings involve:

  • Verifying that circuit breakers, isolators, and residual current devices (RCDs) functioning correctly and are properly labeled.
  • Determine that all of the protective conductors are working properly.
  • Measure the polarity of the main circuit box and components.
  • Make necessary repairs and recommend upgrades.
  • Assess energy consumption patterns to identify areas where energy is being used inefficiently and make upgrade recommendations.
  • If needed, recommend energy-efficient lighting, switching to LED to consume less energy.
  • Assess the functionality of HVAC systems and recommend upgrades if necessary.
  • If necessary recommend replacing inefficient office equipment with newer equipment that is designed to use less power.
  • Recommend and install smart building technologies and energy management systems that optimize energy use.

Renewable energy, such as solar, is also a consideration for reducing energy costs. Electricraft, Inc. also installs commercial, residential, and public works solar systems that can dramatically reduce the company’s energy bill.
