Over the past six years, we have been remodeling our stores to become more energy efficient through the installation of LED lights, efficient refrigeration and HVAC systems, and solar PV systems. These efforts demonstrate our commitment to the reduction of fossil fuel energy consumption, our business continuity strategy considering we are in a hurricane-prone zone, and our social responsibility to reduce the negative impact on the health of our people and environment.
In 2013, we began the journey and substantially completed retrofitting all of the lighting in our locations with LED lights. The process was high risk—the technology was not truly tested and some products were questionable—but we had a lighting challenge at our club store, where our incandescent high bay lamps were costly to maintain and provided poor quality lighting for the facility. After numerous customer complaints, we decided to change out the lights to a more efficient and effective solution. We then decided to expand this project to all our facilities.
Six of our 11 stores were remodeled between 2014 and 2017, during which we installed more modern and efficient refrigeration and HVAC systems. The work is ongoing, and our intention is for all HVAC systems to work effectively with the refrigeration system to ensure proper cooling and dehumidification. This will ultimately result in a more comfortable shopping environment for customers.
In January 2019, work commenced on the installation of two photovoltaic systems at two locations (based on the maximum allowed by legislation) to further reduce our energy consumption of diesel-generated electricity. A photovoltaic system, also known as a Solar PV system, is an energy system that is designed to transform the energy from the sun into electricity by means of photovoltaics, also known as solar panels.
Our customers have been happy with the upgrades, seeing a noticeable difference in lighting and commenting on how pleased they are that the stores are remodeled within a six-week period. Our stores have also benefitted from a significant reduction in energy costs—at the end FY 2016, we had realized a reduction in energy usage of approximately five percent, resulting in over EC $700,000 (U.S. $260,000 lower electricity cost).
The following affect the cost of these solutions:
