Maire Tecnimont’s headquarters in Milan is an example of sustainable architecture with a high energy classification: it produces about 30,000 Kwh from installed photovoltaic panels and several energy saving systems in offices. Such systems have resulted in the achievement of an excellent level of zero local emissions of CO2 eq. To identify improvement areas, official energy audits were performed at the subsidiary KT – Kinetics Technology S.p.A. headquarters in compliance with Italian law. The Group’s energy intensity factors are calculated using both direct and indirect energy consumption as a numerator and man hours worked as a denominator. Worked hours have been acknowledged as representative of the Group’s overall activity.
In 2018, the Energy Intensity indicator reduced on 2017 both for Home office and Construction sites, from 12,451 in 2017 to 11,048 KJ in 2018 for Home Office and from 25,911 in 2017 to 23,849 kJ in 2018 for Construction Sites.
The main sources of water for sanitation and civil purposes (canteen, toilets, flushing wc…) used by the companies located in Maire Tecnimont Headquarters in Milan are provided via public supply network and, for a small portion, via the rainwater collection systems on the roof. The facilities of the complex use groundwater to feed Heating Ventilation Air Conditioning (HVAC) systems, both for heating and air conditioning; groundwater is returned to the soil without any significant chemical change, aside from a heat exchange. Wastewater products enter the urban sewerage network (as is the case for households) and thus no discharge authorization is needed in accordance with the current local law. Over the last three years, total water withdrawn from municipal water supplies or other public or private water utilities were: 65,610 m3 in 2016, 53,234 m3 in 2017 and 41,145 m3 in 2018. The same quantity of water was discharged to sewers over the last three years. In 2016, 954,600 m3 of water were withdrawn (and consequently discharged), while in 2017 the amount was 1,404,060 m3 and 1,494,510 m3 in 2018. During the construction phase, the topic of safeguarding water resources is part of the initial training and the environmental promotion campaign. In respecting Client rules and the local laws, no water discharge to the public sewer or directly to the sea and rivers is allowed.
