Energy Saving Tips for Commercial Refrigeration

Written by J & S Electrical Contractors on . Posted in Blog.

Essential to food operations and grocery stores, commercial refrigeration equipment operates round-the-clock and contributes to high energy bills. According to the US Department of Energy (DOE), commercial refrigerators typically consume up to 17,000 kilowatt-hours of electricity and large ones around 38,000 kilowatt-hours. Selecting energy-efficient models and making a few operational changes can make a significant difference to your energy bills.

In this article, our experienced commercial electricians share 7 tips to help reduce your energy usage on refrigeration:

  1. Make sure there is adequate space around the equipment: Proper air flow over the heat exchange coils increases efficiency and helps maximize equipment lifespan. Avoid placing refrigerators near prime cooking appliances that emit heat.
  2. Keep the refrigeration system clean: Making sure the condenser and evaporator coils are dust-free helps improve heat transfer, thus lowering the amount of energy used. Follow the manufacturer’s recommendations for equipment maintenance.
  3. Ensure that gaskets have a tight seal: This prevents warm, humid air from entering the refrigerator that makes it work harder to keep the inside cool. The cooler your refrigerator, the less energy and wastage of food!
  4. Turn off door heaters: Only keep them on when condensation is visible on the doors. Installing adaptive controls which turn on and off automatically when necessary reduces your effort and energy bills.
  5. Install motion sensors for case lighting: Also consider upgrading to LED lighting in refrigerators. In addition to consuming less energy and lasting longer, they give off less heat.
  6. Add night covers or curtains: This prevents refrigerated air from escaping so your commercial refrigeration equipment does not have to run at full power after business hours.
  7. Install automatic door closers for walk-in coolers: This prevents loss of energy from open doors. Never prop open the doors either.

In 2014, the DOE announced new standards which aimed at making commercial refrigerators and freezers 30% more efficient. Replacing old equipment with newer energy efficient models will deliver savings on every bill. Products with the Energy Star label are, on an average, 20% more efficient than standard models.

The Importance of GFCI Protection for Commercial Kitchens

Written by J & S Electrical Contractors on . Posted in Blog.

GFCI (ground fault circuit interrupter) protected receptacles are critical to ensure safe operations in institutional and commercial kitchens, and wet bars. Poorly maintained electrical appliances, damaged electrical cords, wet floors and lack of electrical safety training for employees results in the risk of electrical shocks in kitchens. GFCI protection has therefore, become mandatory. The National Electrical Code (NEC) requires that all receptacles (including 15- and 20A, 125V receptacles) be GFCI-protected, irrespective of whether they are located in countertop areas. More sensitive than circuit breakers, they act faster to protect you, your staff or patrons from electric shock which causes burns, heart arrhythmia or nervous system damage, even death. Kitchens in restaurants, hotels, schools, churches, dining halls, and similar facilities must have GFCI protection.

GFCI Protection vs Regular Circuit Breakers

It is important to understand how GFCI and regular circuit breakers work. Standard fuses and circuit breakers protect the wiring and electrical system from a fire in the event of an overload, but they are not adequate to protect people. Also, the current required to trip a regular circuit breaker is many times greater than the amount needed to inflict a fatal shock.  The GFCI on the other hand, is specifically for protection from electrocution, not fire. The device typically kicks in as little as 1/40th of a second, potentially saving you or your staff from electric shock.

Types of GFCI Protectors

There are two types of GFCIs. GFCI receptacles are most common and similar to a regular wall outlet. GFCI circuit breakers replace traditional ones and provide protection to all receptacles on that particular circuit. An experienced commercial electrician can help you evaluate the pros and cons of each to make an informed decision. Test your GFCI receptacle or circuit breaker every month to ensure it is working properly.

At J & S Electrical Contractors, Inc., we offer tailored solutions to install GFCI protection for the outlets in your institutional or commercial kitchen. Our expertise with design and installations helps optimize safety and energy efficiency.

5 Tips on Parking Lot Lighting

Written by J & S Electrical Contractors on . Posted in Blog.

Are you considering installation or upgrades for your parking lot lighting? A well-lit commercial property provides a welcoming space for your clients. It also promotes employee and visitor safety by preventing accidents and deterring criminal activity. Our expert commercial electricians share 5 important points to consider when formulating an efficient parking lot lighting plan.

  1. Evaluate your needs or current lighting: Intensity, uniformity, color, energy-efficiency and cost are important aspects of lighting design. For existing lighting, survey the light levels to determine what changes need to be made.
  2. Determine how much light is adequate: This is largely dependent on the type of business you run. An auto dealership and retail complex might want brighter parking lot lights than an office building that is largely unused after-hours.
  3. Maintain uniformity: Typically, the distance between lighting fixtures is responsible for uneven lighting. Presence of trees and other types of landscaping can also make the task more difficult. Your commercial electrician might have some suggestions on how to overcome landscaping obstacles. For existing lights, map out high and low illumination areas to pinpoint where changes are required.
  4. Consider cost-efficient LED lighting: LED lamps start up instantly and provide up to 100,000 hours of light. They can be replaced easily, and the design flexibility supports retrofitting fixtures to existing poles. In addition to maintaining consistent light intensity and temperatures for the lifespan of the lights, you also get added safety with shock and vibration resistant fixtures.
  5. Invest in surge protection: Your commercial electrician can identify and install the right surge protection device (SPD) which will withstand spikes and save you thousands of dollars in damages to your newly-installed parking lot lighting.

Warehouse Lighting Controls May Lower Electricity Costs

Written by J & S Electrical Contractors on . Posted in Blog.

Efficient warehouse lighting controls can help lower your energy bills and overall operational costs significantly. Keeping all lights on all the time is an expensive way to run your business. Our expert commercial electricians share simple ways to make your lighting more cost-efficient. 

  • Install motion sensor lighting: They sense occupancy and either dim or turn lights off when the space is not in use.
  • Use dimmers: Upgrade to ballasts and LED power drivers with dimming capabilities. Lowering brightness even by a fraction can reduce your energy usage and costs.
  • Switch to scheduled lighting and task tuning: Sophisticated centralized controls allow you to schedule when lighting is turned on and off based on the time of day, week and month to conserve energy. You can reduce usage even further by tuning lighting output to occupant requirements rather than have standard bright lighting across the facility.
  • Join a demand response (DR) program: Many utilities offer reimbursements for participating in a DR program which allows them to control lighting and thermostats based on the load factor.
  • Consider daylight harvesting lighting systems: Sensors determine when artificial lighting is required based on the availability of natural light.
  • Invest in plug load controllers: Having the ability to automatically cycle loads off based on work hours and occupancy can result in measurable energy savings.
  • Promote personal control: Educate your staff about energy efficiency and encourage them to turn off lights when a space is not in use. Installing remote controls, desktop dimming switches and virtual online switches can help with your energy conservation efforts.
  • Have an energy management strategy: Centralized energy management software tools will enable your warehouse manager to monitor and control usage more efficiently. Some systems are also able to detect when individual lights are out or malfunctioning. This helps with efficient maintenance and repairs.

Importance of Surge Protection

Written by J & S Electrical Contractors on . Posted in Blog.

Surge protection should be an integral part of every industrial, commercial and residential electrical system. Yes, it is true that surges in electric current are natural and have always occurred. However, the increasing use of sensitive electronics which are highly susceptible to damage make surge protection critical.

What causes a surge?

Power surges are quick, temporary spikes in voltage that occur when the electrical charge in the circuit gets a sudden boost. One study revealed that 63% of surges originated from within the facility. What caused them? Load dynamic changes on large machines, motors and light load panels turning on and off, etc. The remaining 37% were the result of external factors such as utility grid switching, electrical accidents and lightening.

What surge damage means for businesses

Utility experts estimate that power-related problems cost US companies more than $80 billion a year.

Below is a quick overview of how surge damage drives up your business expenses:

  • Higher equipment repair and maintenance costs
  • Expense of replacing motors, machines and electronics that are destroyed
  • Shorter equipment lifespan leading to early replacement expenses
  • Equipment failure resulting in unplanned downtime and loss of productivity
  • Electrical accidents and workplace injuries

How to protect your facility from surge damage

A high quality surge protection device (SPD) minimizes the risk of internal and external surges and saves you thousands of dollars in damage.  A properly-designed and installed SPD can withstand significant voltage spikes. An experienced commercial and industrial electrical contractor can help you find the right one for your facility as well as connect it correctly to your electrical system.

7 More Tips to Reduce Business Energy Costs

Written by J & S Electrical Contractors on . Posted in Blog.

According to the EPA’s ENERGY STAR program, combined annual energy costs for U.S. commercial buildings and industrial facilities amounted to $400 billion as of March 2015. With an earlier survey in 2007 revealing that almost 30% of this energy is used inefficiently or unnecessarily, reducing any wastage is a top priority for business owners.

Our team of experts here at J&S Electrical offers more tips to help you streamline usage and reduce your energy bills.

Upgrade outdated equipment with Energy Star solutions: Heaters and air conditioners lose their efficiency over time and tend to use more power than necessary to achieve set temperatures. Many local governments provide tax incentives for purchasing energy-efficient appliances for your business and these can help offset your cost.

Maintain your HVAC system: Regular tune-ups and cleaning as well as timely repair will keep your heating and air conditioning equipment functioning at optimal efficiency.

Optimize use of daylight: Try to make use of natural light as much as possible. Installing skylights is one way to reduce the need for artificial lighting. Also switch off extra lights in corridors, stairways, conference rooms, workstations, the reception area and cafeteria.

Consider switching to solar power: While installing solar panels might seem expensive initially, solar power is free and the setup cost can be recovered in a few years through the continual energy savings. The federal government also offers a tax credit for solar systems installed at business premises which can help reduce your expenses.

Plant more trees on your business premises: They can shield your building from the summer heat as well as the cold winter winds which will help reduce your cooling and heating bills.

Involve your employees in energy-efficiency initiatives: Educate them about the energy-saving features of your high-efficiency equipment and appliances. Encourage them to come up with their own ideas for reducing energy usage and cost. Provide incentives for achieving goals; it is a great way to keep employees invested in energy-saving programs.

Set energy saving goals: Assess your energy usage and set clear goals for improving your efficiency. Identify areas of improvement so you can monitor and measure progress.
