Three certificates dominate the Polish office market: the British BREEAM (levels from Pass at 30% to Outstanding at 85%), the American LEED (Certified to Platinum) and WELL, which assesses occupant health and comfort in 10 categories rather than environmental impact. A certified building costs more to build, but lower service charges, lower vacancy and more lease renewals mean tenants knowingly choose green buildings.
Global climate change, urban development and growing environmental awareness have increased the importance of construction based on principles of respect for nature. What impacts a project's environmental performance and how can we identify a building that is truly environmentally friendly?
Building certificates
Several different building certification systems exist globally. However, there are no universal, international standards for assessing developments. Under EU Directive 2010/31/EU, from January 2021 every new development must demonstrate near-zero energy consumption.
Most popular office certificates in Poland
Poland ranks at the top of Central and Eastern European countries with the largest number of certified buildings. The most frequently awarded certificates are BREEAM, LEED and WELL.
BREEAM
BREEAM is the most frequently chosen method for certifying office buildings in Poland. Created in 1990 in Great Britain, it is applied in 77 countries. Buildings are rated at levels: Pass (30%), Good (45%), Very Good (55%), Excellent (70%), Outstanding (85%).
LEED
LEED is an American building certification method used in 168 countries. The system is similar to BREEAM. Buildings receive points at levels: Certified (40-49 pts), Silver (50-59), Gold (60-79), Platinum (90-110).
WELL
WELL Building Standard focuses on ensuring occupant comfort and health. It is applied in 48 countries and has 10 categories: Air, Nourishment, Water, Light, Movement, Acoustics, Thermal Comfort, Materials, Mind, Community. The certificate is awarded for 3 years.
Impact of certificates on rent levels
Costs associated with building a certified facility are significantly higher than for non-certified buildings. However, thanks to the technologies applied, it is possible to achieve lower service charges. Tenants knowingly pay more for green buildings.
Summary
Environmental building certificates have become the standard in Poland's real estate market over the past few years. Sustainable buildings are characterised by lower vacancy, and tenants are more inclined to renew their leases in such properties.
