Setting a new standard for retrofitted offices

Case Study Savills Portugal

Savills is a global real estate services provider with a network of more than 39,000 people in over 600 offices across the Americas, Europe, Asia Pacific, Africa, and the Middle East. Savills advises corporate, institutional and private clients to acquire, lease, develop or realise the value of residential and commercial property in the world’s key locations. More recently, their focus in Portugal has shifted to sustainability and retrofitting buildings. Together with hello energy, they are adding value and engaging with the communities surrounding them. 

The challenge

Going net-zero is one of the main drivers for Savills and their clients. In order to make that transition, Savills wants to get their own reporting in order and create structures for accountability and governance. Moreover, they want to create a wider impact on society and the environment. They welcomed new expertise into their team, as Nuno Fideles, Associate Architect, became the first accredited BREEAM professional in Portugal, and Bárbara Clemente, Associate Architect, became accredited WELL professional, together with other colleagues in the team. Part of their local strategy is to retrofit a number of assets to create a new sustainability standard for both offices and residential buildings.

The solution

MB4 in Lisbon, owned by Avignon Capital and housing Savills Portugal offices, serves as a flagship example of inclusive and accessible amenities that have a positive impact on the environment and employee wellbeing, such as a work café, an installation for cyclists, daycare facilities and many more features such as photovoltaic plants that powers 20% of the building. hello energy’s data services assisted with the implementation of installation 20 indoor climate sensors, screen services in the building and connecting all energy data points. 

With all these insights gathered such as visualising the building’s consumption, hello energy helps to start a dialogue with the tenants by inspiring them to take simple and fun actions to improve.

Not just for MB4, but for many more buildings in Portugal.
