Sustainability is integral to our strategy and a guiding principle in our (re)development projects. ESG leadership is considered key to performance, and an important source of competitive advantage. We feel responsible for the long-term implications of what we do from both an environmental and a social perspective. Moreover, we are convinced that contemplating these long term implications ultimately deliver the best long-term value.

FOSTERING TENANTS’ WELL-BEING
Well-being relates to the health and happiness of tenants, which ultimately results in higher productivity, and is therefore an important guiding principle in NSI’s (re)development projects. It is the starting point of the design of both the exterior and the interior of the building. For example, by making optimal use of daylight.
A good example of such a feature, is optimising the use of daylight. In our Laanderpoort project, the transparent facades and the 11 spacious atria in the building will allow through a significant amount of natural daylight on the office floors, which is essential to how people feel and how productive they are. . Furthermore, the centrally located and aesthetically pleasing staircases are a constant invitation to forego the elevator and take the stairs more often.
Furthermore, NSI will install state of the art air treatment systems in all of its development projects. The systems monitor temperature, CO2 levels and humidity to optimize the thermal comfort and quality of the air. Through the buildings’ active and SMART climate ceilings, tenants are able to individually set the temperature and lighting they prefer at any given time. The lay-out and interior is designed to improve the state of mind of people by using bio-based materials and natural colours according to biophilic design principles. Greenery inside and around the building contribute to capture CO2 and improve the well-being of tenants.
In the Laanderpoort project these elements are combined with an extensive public indoor sport facility to provide an integral well-being offer.

USING SUSTAINABLE AND BIO-BASED BUILDING MATERIALS
Buildings represent a significant proportion of energy consumption and carbon emissions. Using sustainable and bio-based building materials are key to mitigate environmental damage. With its development activities NSI aims to minimise emissions in the
built environment.
For the development project Vivaldi III, a 86-metre high office tower, NSI is using timber as the main building material for the structure of the building-a novelty in the Dutch office market at this scale -, having significant impact on both the sustainability credentials of the building and the well-being of its occupants.
The use of certified timber from European forests is preferable to other traditional materials like steel and concrete (so-called abiotic materials). The total CO2 benefit of using timber instead of abiotic materials is based on the CO2 s captured by the timber added with the CO2 avoided by not building with abiotic materials. Trees take CO2 out of the air and convert it into other carbon compounds. Around 0.75 tonnes of CO2 are pulled from the air for each m3 of wood. The Vivaldi III project contains approximately 4.610 m3 of timber storing 3.480 tonnes of CO2 that will not contribute to the greenhouse effect during the lifespan of the building and the additional lifetime of the timber being used.
The use of timber also lowers the embodied carbon footprint by avoiding the production of steel and concrete using high energy consumption and related CO2 emissions.

CREATING COMMUNITIES
NSI strongly believes vibrant multifunctional and accessible urban areas will be the preferred future office location. This refers to not only the location itself but also the quality of the surroundings, safety and the facilities and services being offered. NSI has become a major stakeholder in some of the most attractive and growing urban areas in its target cities, allowing the company to play a role in the transformation of these districts.
Amsterdam Sloterdijk and Amsterdam Zuidoost are clear examples of up and coming locations undergoing rapid transformation. With multiple assets at these locations, NSI can take an active role in the development of these areas and is engaging with stakeholders to transform these areas into vibrant urban districts, where people not only work but also live and play. Mobility and accessibility are a key aspects in creating such environments. Optimal infrastructure for cyclists, pedestrians and a good public transport network are crucial.
At the asset level, NSI aims to have a strong connection from the outside to the inside of its buildings. Entrances are inviting, warm and publicly accessible, creating a lively atmosphere.
