NSI’s three main sustainability ambitions

Future-proof investments

Expanding the total lifespan of assets by developing and redeveloping future-proof investments has been identified as a key element in driving long-term ESG performance. Future-proof investments are buildings that are adaptive and innovative by nature – buildings that anticipate market trends, offer a fluid mix of spaces, deploy new technology, have great accessibility and are located in multifunctional areas. Moreover, the impact on climate change should be a consideration in these buildings. Future-proof investments should be flexible for transformation and focus on circularity, both in the construction and exploitation phase. By applying these future-proof principles, NSI aims to provide healthy, inspiring and flexible working environments for its tenants with great accessibility and the necessary facilities nearby, while minimizing their impact on the environment.

That means that NSI’s investment criteria include ESG metrics that promote flexible building design (suitable for multi-tenant and potentially flexible in use) and sustainable innovations.

Energy & Carbon

NSI aims to minimise its impact on the climate and contribute to achieving the Paris Climate Agreement goals. In doing so NSI will reduce its carbon footprint in the coming years in its quest to
become carbon neutral by 2035. This reduction will be achieved by combining energy efficiency and green energy sources in the construction and exploitation phases.

Regular maintenance works are used to improve ESG metrics, including measures to reduce energy consumption such as more efficient lighting and heating systems, cooling generation systems, roof upgrades and improved insulation.

In the past four years we fully renovated around 80,000 sqm of office space, including a full upgrade of the lighting with 25,000 LED units with motion sensors. We have also started to minimise gas usage and over 40% of the portfolio by sqm currently uses sustainable district heating, heating pumps or ATES systems. We are committed to increasing the use of solar energy, but due to our recent disposals only 2.4% of our electricity usage is currently generated this way.

NSI managed to significantly upgrade the energy label of the assets in its portfolio in recent years. By value 85% of the office portfolio has an energy label of C or better. The Dutch government has stipulated that all office buildings in the Netherlands should have an energy performance certificate (EPC) with at least a C label by 2023. It is NSI’s ambition to not only achieve
but exceed this minimum EPC grade by 2023.

NSI engages with its tenants to improve their energy efficiency and help them reduce their carbon footprint. Green leases will be used to formalise agreements between NSI and its tenants aimed at improving energy efficiency and reducing their carbon footprint.

Energy consumption is mapped and analysed at the level of each asset, if possible at individual tenant level, in order to identify and prevent unnecessary usage. Sweco has been contracted as a
business partner to help NSI deliver annual energy savings of 7%. Also, employees are encouraged to help reduce NSI’s carbon footprint, both personally and with regard to their specific portfolio. NSI aims to minimise travel emissions and the impact of commuting.

NSI’s car fleet will migrate to a green car fleet. Expired lease contracts will be replaced by contracts stipulating electric cars. The non-electric car fleet will ultimately be phased out completely. 34% of the car fleet was electric at year-end 2018 and 25% is plugin hybrid.

Health & Well-being

NSI aims to create healthy, inspiring and flexible working environments for its tenants and promotes a healthy way of working for its employees. Moreover, NSI aims to have a positive
impact on the community.

People spend over 90% of their time indoors, which means that the ‘indoor environment has a significant impact on their health. NSI is committed to providing a healthy indoor environment by choosing materials and technologies that are designed to improve the indoor space in terms of air quality, comfort, installations, lighting and sound. And by designing public spaces and stairways in ways that entice people to walk and providing facilities and amenities that support and promote a healthy lifestyle.

NSI considers an active lifestyle important to the health and well-being of its employees, and it therefore promotes physical activity, healthy nutrition and a healthy work-life balance.
