We installed 561 solar voltaic cells forecast to generate over 300 kWh per year of electricity at its primary location, and this will provide 90% percent of all electrical needs for this facility.

We have has replaced insulating energy curtains in over 650,000 square feet of greenhouses. This is estimated to save 55,000 btu of natural gas used for heating.

In 2018 Westerlay installed a 300,000 square foot irrigation water recycling catch system water use by 38 percent. This system additionally reduced natural gas consumption by 11% by lowering humidity.

Westerlay will be installing 16 high efficiency de-humidification units in its Foothill facility in Q4 2024.  These units will reduce natural gas usage at this facility by an estimated 20% or by allowing the greenhouse energy curtains and vents to remain fully closed during cold nights.

To minimize pesticide usage, we introduce naturally occurring predators to keep the pest population in check, making for a cleaner environment and a healthier plant.

Exhaust from our boilers is captured and injected into the greenhouse as pure CO2. This increases photosynthesis by 10-15% spurring plant growth re-captures carbon in the plant itself.

We have achieved an ‘A’ rating every year since 2015 from MPS, the internationally recognized independent horticultural rating agency.  Since 2023, Westerlay is also working with MPS to measure its carbon footprint so that we can target and measure annual improvement.
