Graniterock knows a thing or two about sustainability.

Recognizing that their reliance on utility power was becoming increasingly costly and that supporting a fossil fuel driven energy economy was inherently unsustainable, they decided to take action, but were unsure how to get the most impact.

We worked together to identify the most economic and highest impact opportunities to reduce their utility energy needs and generate clean power on site. Following our recommendations, they chose to pursue a complete full Zero Net Electric retrofit of their Watsonville Headquarters.

New Solar +
The non-penetrating ballasted solar installation retains the roof membrane integrity and allows for a simple and efficient installation.
Additional Upgrades
New interior efficiencies saved money and improved working conditions through better interior lighting, customizable heating, and a heat and UV blocking window film.
Minimal Employee Disruption
Careful logistical planning and coordination minimized disruption in a fully occupied office space containing over 200 employees.

LOW-E WINDOW FILM

Blocks heat & harmful UV rays and allows employees to sit by windows free from intense heat & blinding glare. Reduced thermal load on the building improves energy efficiency through decreased need for air conditioning.

AI Based HVAC System

AI based HVAC optimization controls improve performance throughout open warehouse with 20’ ceilings and mezzanine level across half of the space.

Upgraded LED Lighting

Designed for hundreds of people at desks and in conference rooms, new lighting creates a more comfortable working environment while significantly reducing energy costs.

Visible Sustainability Commitment

Overlooking Hwy 101, the flagship facility is seen by 1,000’s of people daily - a highly visible commitment to sustainability. Our approach created superior economics that made the CFO happy while having an outsized impact on Graniterock’s carbon footprint.

Working with Mynt we realized we could transform our corporate headquarters office in Watsonville, CA into a showcase of our values in a way that didn’t break the bank and also made it a more comfortable place to work. Mynt’s solution is reducing our energy consumption from the grid about 90% and paying for itself through lower utility bills.
