About us

We make it happen. Sustainable

BuildGreen is one of the leading ESG and sustainability consultancy firms in Central and Eastern Europe with a team of experts who provide specialist advice in sustainable design, carbon neutrality, decarbonization, audit and certification. We help clients to understand their material impacts and risks, establish ESG goals and build ESG strategies that drive change. We also help clients to calculate their Scope 1, Scope 2 and Scope 3 emissions, set goals and develop reduction strategies.

Founded in 2010 by Razvan Nica, BuildGreen was the first Romanian company to offer a range of green building certification services and has built a reputation as a very reliable partner having achieved over 350 certifications for some of the most reputable developers and asset managers in Central and Eastern Europe.

Following a similar path to BuildGreen, Czech based, green-gain were founded by Andrew Caistor in 2009. As the first BREEAM assessor organization in Central and Eastern Europe green-gain played a major role in raising awareness of BREEAM and in steering clients and project teams in its delivery.

After several years of collaboration, the 2 companies eventually merged and now operate under the brand name BuildGreen with offices in Bucharest and Prague. Building on their success and reputation as a leader in their field, BuildGreen has assembled a team of in-house specialists to offer a wide range of ESG and sustainability services. Our extensive knowledge and expertise are backed by a passion to serve those who share our values.
