Product design meets the 3R requirements (Reuse and Recycled rate=80%, Recovery rate=85% ).
The total waste produced by Taipei Headquarters in 2019 amounted to 42.38 tons and the recycling rate was 64.94% . The total waste produced by Tainan in 2019 amounted to 188.84 tons and the recycling rate was 51.98%.

Environmental Performance

Special Edition on Sustainable Environment – Energy-Saving Rack Laboratory

Wiwynn took the lead to introduce the energy-saving technology that is synchronized with a world-class data cen-ter and designed the novel rack integration laboratory. Fresh air, the cold/hot aisle design, and the programmable settings of aisle temperature are applied to reduce demand in the laboratory for cold air and waste of resources. Meanwhile, R&D staff of Wiwynn can have a better understanding of the application setting and world-class ener-gy-saving ideas of its products in customers’ data centers.
While the natural cooling laboratory was being designed, it was found that the rapid changes in temperature and humidity in northern Taiwan needed to be addressed and so did the limited construction conditions in an industrial

building. As a result, constant monitoring, adjustment, and verification of many parameters were required during design in order to realize optimal energy-saving efficacy. Eventually, Wiwynn realized the goal of primary natural air cooling and secondary custom cooling in a room of 36 pings (1 ping = 3.305785 m2 ). The automatic fire preven-tion and automatic environmental control were set as well. It can, in particular, automatically adjust air inlet/outlet and the cooling mode when there is a typhoon and automatically estimate and display the average PUE. The labo-ratory as a whole can support the integration testing of up to 34 racks and render extremely good air-conditioning and energy-saving efficacy.

Remote Monitoring Management and Programmable Modulation Management System:

Cold water temperature and motor activation volume, heater and air ventilator status, laboratory temperature, humidity, and temperature, automatic fire prevention equipment status, and laboratory air-conditioning and IT electricity consumption are monitored in order to experiment and adjust optimal parameters to accomplish electricity conservation with the opti-mal PUE value.

Natural air intake within the applicable range of temperature and humidity was properly used. The use of a heater to bring down the relative humidity was minimized. The temperature in the cold channel during non-working hours was flexibly adjusted. Besides the above-mentioned key techniques, the parameters were observed and laboratories studies took place for several months in a row to eventually render natural air intake laboratory optimized parameters that are suitable for an island climate to significantly enhance the PUE (Power Usage Effectiveness). From the PUE mean of 1.8 for a traditional machine room to an annual mean of 1.16, the electricity consumption efficiency was enhanced by 35%.
