One key building block in the property industry’s sustainability initiatives is certifications. Essentially all new major office blocks and logistics buildings have some form of certification today.
Environmentally certifying an office building means taking responsibility for a sustainable future. But it is much, much more than that. An environmentally certified building has lower energy consumption, has a higher value on the market, and is more attractive to tenants and employees who are becoming increasingly environmentally aware. There are several different kinds of sustainability certifications, which involve third-party audits of sustainability programs and the building’s sustainability performance. Castellum has chosen to work with the following:
Miljöbyggnad is a Swedish system for the environmental certification of buildings. The system is owned and developed by the Sweden Green Building Council, which also issues the certifications. Miljöbyggnad has three levels: Bronze, Silver, and Gold.
Castellum certifies all newly built office properties under Miljöbyggnad level Gold. All newly constructed warehouse and logistics properties are certified under Miljöbyggnad level Silver.
BREEAM, from the United Kingdom, is the world’s most frequently used system for the environmental assessment and environmental certification of buildings. BREEAM-SE is an adaptation of the system to Swedish conditions. The system is used to certify newly produced buildings in a number of areas such as energy consumption, indoor climate, water management, and waste management. Stringent requirements are set on everything from biodiversity to construction materials and energy efficiency. Extra points can be awarded for the level of innovation used in a building’s technical solutions.
BREEAM In-Use was created in 2009 to improve existing buildings and targets primarily property owners, investors, property managers, and tenants.
The LEED system, from the United States, ranks as the best-known assessment system internationally and has the Sweden Green Building Council as a partner. There are several different LEED systems, from individual residences to entire cities. The certification is divided into four levels: Certified, Silver, Gold, and Platinum. LEED aims at a transformation of the construction industry through strategies for achieving seven priority goals:
Using LEED (O+M), property companies can certify existing buildings and focus on their operation and maintenance.
NollCO2 is a supplementary certification for Miljöbyggnad, BREEAM-SE, LEED, and the Nordic Swan ecolabel that is used to help new constructions achieve a net-zero climate impact. NollCO2 is a highly demanding standard that will make it possible for Sweden to achieve its goal of climate neutrality by 2045.
The certification, which is managed by the Sweden Green Building Council, means that the climate impact of a property during its production phase is to be reduced by at least 30 per cent compared with traditional construction. Throughout its entire life cycle, the climate impact of the building will be reported and balanced using measures that lead to a net-zero climate impact. Achieving this requires precise initiatives early on in everything from choice of materials and technical systems to suppliers and contractors.
The WELL Building Standard is a global certification system that is aimed at improving health and wellness for people living, working, and using various built environments. The certification system is science based.
With new construction of offices, the possibility of WELL certification for the property is always investigated. By working with the system, Castellum can create positive health effects that help its tenants and their employees perform and be at their best.
EU GreenBuilding focuses on improving the efficiency of energy usage. The requirement is to improve energy efficiency by 25 per cent, or to use 25 per cent less energy compared with new construction requirements in the building regulations (BBR) of the National Board of Housing, Building and Planning.
