Typical Warehousing Electricity use in Newfoundland & Labrador
Space heating is the biggest consumer of electricity in Newfoundland and Labrador warehouses at 36%, followed closely by lighting at 33%. Refrigeration systems and HVAC fans and pumps also use significant electricity in this sector, offering four great areas for your company to conserve energy and become more energy efficient. Don’t forget you can get back up to $50,000 when you make eligible energy efficient upgrades to your business.
- Programmable thermostats – Save up to 10% in heating costs when you install programmable thermostats and get a takeCHARGE rebate. Calculate your rebate.
- Install a mini-split heat pump – These units are great for small offices and are economical to install. A mini-split heat pump can save you over 40% on your heating costs. They also offer the option of air conditioning for those warm summer months.
- Cold climate or low temperature air source heat pump (ASHP) systems are more efficient than conventional electric baseboards and are a great choice for larger buildings. These systems can achieve savings up to 50% over conventional electric baseboards.
- During the winter months, open the blinds during the day to allow the sun to assist with heating office spaces.
- Address any building envelope issues:
- Roof Insulation.
- Wall Insulation.
- Gaps around doors, windows and entry point into the facility.
- LED Wall Packs – Get $25 back for each LED wall pack you install and save up to 70% of electrical energy costs.
- Occupancy sensors – Save up to 40% on lighting energy costs when you install occupancy sensors. Calculate your rebate.
- When replacing fluorescent lighting, install high efficiency T8, T5 or LED. New energy efficient lighting such as LED can save you over 35% on your lighting energy costs.
- Replace incandescent Exit signs with LED. Get a $20 takeCHARGE rebate at select locations and save $300 over the life of the sign from reduced energy use and materials and labour for bulb changes.
- Minimize exterior lighting. At night only use what you need for safety and security purposes.
- Use day-lighting whenever possible.
- Encourage employees to turn off the lights at the end of the day.
- Replace evaporator fan motors with ECM motors. This is especially effective for walk in coolers and larger fans. ECM motors can reduce energy use by over 50%.
- Install variable speed compressors. A compressor driven by a variable speed drive, better matches the refrigeration load and only works as hard as it needs to, thereby reducing energy requirements.
- Upgrade refrigeration to floating head pressure controls to reduce energy needs. The control system takes advantage of lower outside temperatures to reduce the refrigeration energy.
- Use a heat recovery water heater to take advantage of “free heat” produced by the refrigeration equipment. Heat recovery water heaters use this type of waste heat as a means to heat water.
HVAC Fans and Pumps
- For larger offices, the use of a Building Automation System (BAS) will efficiently manage energy usage for the building. These systems can save up to 30% in energy costs.
- Where applicable, install adjustable speed drives on fans and pumps. Adjustable speed drives can decrease energy use by over 35%.
