A commitment to reducing its environmental footprint, while managing costs, has been the catalyst for OfficeMax’s new solar project at Highbrook Business Park.
The customer’s facility on Sir Woolf Fisher Drive has recently been expanded to accommodate its business growth. Being a progressive company, the office product and business consumable reseller is extending its sustainability focus with the installation of a 286kWp solar energy system. Initially developed in 2008, the warehouse and distribution centre incorporates OfficeMax’s national office, accommodating a team of more than 400 people.
The new warehouse expansion adds 7,350 sqm to the existing 18,900 sqm facility. The northern orientation and extensive roof area make the building ideal for solar technology. An 880 panel, 286kWp photovoltaic solar system is currently being installed on the roof of the warehouse extension. Due for completion in September 2020, the size of the system has been based on a demand load assessment of the expanded building.
Modelling shows that solar energy will provide 22.5% of the forecast 1.8 MWh of electricity required by OfficeMax, equating to an annual cost saving of around $35,000*. One of the benefits of commercial solar systems is the ability to match electricity demand with peak solar energy production. Electricity that is generated but not used (on days or times when power demands are reduced) is sold back to the grid.
With forecast annual production of over 400,000 kWh the system is expected to generate the equivalent electricity needed to power 57 New Zealand homes, while offsetting 39 tonnes of CO2 per annum.
