Benefits

BenefitsLiving Public Space is good for people, climate, nature, and the economy. Investing in green public spaces facilitates sustainable recovery after a crisis and reduces the risk of future crises.

The benefits of greenery are not all equally measurable. Estimating the contribution to healthy mobility and fewer traffic jams may be unclear. The benefits, therefore, are not always included, which makes the business case more complicated.

A joint business case in which stakeholders and multiple departments of municipalities (green, water, health, social, education, transport) work together and contribute to overall costs and to achieving shared outcomes, often turns out to be feasible and successful in practice.

In the urban space, the use of greenery can deliver significant reductions in healthcare costs, a reduction in heat stress and damage due to flooding, According to social cost-benefit analyses, it contributes to social cohesion. Positive economic effects are common. Biodiversity enhancement improves the opportunities for insects that pollinate our food. It also reduces the chance of pests and diseases in the green infrastructure.

Green pays off directly and indirectly. This profit can be stacked and can be realised in different phases of the project. In this chapter you will see how a number of benefits of greenery can be valued in economic transactions. The (indirect) benefits with examples from various other themes can be found under the other green tabs.

Innovation

Green is a sustainable investment that leads to innovation and employment. New/green jobs and revenue models are emerging. Green can be used in many crossovers with other sectors. It lends itself perfectly to integrated solutions that contribute to liveable, resilient cities.

Think of greenery as an investment and not as a cost.

Green investment

Some advantages that can be seen are that green locations are more often awarded in tenders. Plans may be approved more quickly. Greenery may have a positive effect on the buying and selling time of buildings.

Real estate is worth 5 to 15% more in a well-maintained green environment. Both a short walk to greenery and a view of greenery affect the value.

Green façades and (collective) roof gardens can lead to an increase in the value of buildings. Soundproofing by greenery may positively impact the value of real estate.

Green locations can exhibit very different stakeholder and revenue streams than expected. Consider police and security services and insurance companies – there is a noticeable reduction in crime, and damage due to (water) nuisance in an area due to high quality designed urban green spaces.

Project developers are increasingly realising that investing in greenery is not only good for the climate, but that it also promotes the sale of real estate and returns. The occupancy rate of real estate in a pleasant green environment is higher. Higher rents may also be charged. Public investments in green spaces can be recouped through higher tax revenues (WOZ, house value lump sum).

Multiple use of space

A green outdoor space creates new living space in densely populated areas. Public rooftops and collective courtyards are excellent locations to create more living space without using scarce and expensive square meters elsewhere.

Energy costs

Greenery on the roof and façade increases the insulation value of buildings. It can save energy costs: up to 70% in summer for cooling and up to 20% in winter for heating. Green roofing tends to protect roofs better and preserve them for longer. A green roof extends the lifespan of the roof. On average, an extensive green roof lasts three times as long.

Solar panels on a green roof are 6% more efficient due to the heat reduction delivered by evapotranspiration. Trees in the parking lot provide shade and cooling. This leads to less evaporation of fuel from the fuel tank and less energy consumption of the air conditioner.

Well-placed windbreaks protect places and buildings from strong winds. Adequately constructed tree bands can lead to energy savings of up to 10% in adjacent buildings, even if they are already optimally insulated.
