What we have achieved
TechRentals is reducing its operational carbon footprint by increasing our sustainability program. We have embraced renewable energy and installed solar panels at our Head Office in Melbourne and Sydney branch.
Some Examples of our Sustainability program in Sydney include:
Solar Panel Installation
PV Solar Panels on our roof. The installation consists of 200 of 500 W panels and 4 of 20 kWh inverters. Our aim is to create an average of 350 kWh per day (a possible ~70% – 80% reduction in our greenhouse emissions). There will be data monitoring available so we will be able to check-in on the PV performance.
Energy Efficient Lighting
In early March 2021, we replaced all the site’s light fittings with energy efficient LED lights. Comparing our energy usage between this year and last year we can see a ~24% reduction in electricity consumption and in our greenhouse gas emissions – amazing!
TotalCal Solution
TechRentals launched TotalCal – A Calibration Lifecycle Management System for instruments being calibrated. TotalCal provides amongst other things a fully customer focused portal that reduces the need for paper-based calibration records, repair records, and houses electronically all instrument data and calibration records.
