Method: each source value is adjusted from its valuation date to current prices using the CBS price index for existing owner-occupied homes (by province, or by city for Amsterdam, Rotterdam, Den Haag and Utrecht; the national monthly index is used for the most recent months). The midpoint is the weighted average; the range reflects the variation between sources (at least 5%). The home's condition, location along the street, ground lease and individual features are not taken into account. This is not a valuation.

In the neighbourhood of Academiewijk, 73% of homes have higher noise levels than at this address; the average there is 54 dB.
Quiet: typical noise levels for a residential street. Noticeable during the day if you listen for it, but quiet enough at night to leave a window open. The main source is road traffic (45 dB).
Source and methodology
Lden: annual average noise exposure across the day, evening and night (RIVM noise maps 2020, air traffic 2022, wind turbines 2024, 10 m grid). A rough guide, not a measurement at the façade. The WHO recommends a maximum of 53 dB for road traffic and 45 dB for air traffic.
Flooding
0,16 m Limited
If this area floods, the maximum water depth map shows that water here could reach a depth of 0,16 m.
- Homes in Academiewijk that could flood
- 41%
- Of these: water depths over 0.5 m
- 10%
- Maximum depth in the neighbourhood
- 0,60 m
Limited: floodwater can reach knee height in the street. This means wet crawl spaces and gardens, but rarely damage to living areas. A raised threshold and a dry crawl space help limit the damage.
Source and methodology
LIWO (Rijkswaterstaat), maximum flood depth map, 25 m grid; flood probability: Klimaateffectatlas. The depth does not indicate how likely flooding is; dykes and flood barriers are designed to account for that probability.
Air quality
- NO₂ 16,1 µg/m³ above WHO guidelines
- PM2,5 8,7 µg/m³ above WHO guidelines
- PM10 15,9 µg/m³ above WHO guidelines
Polluted air: above the European limits for 2030, usually due to a nearby busy road, industry or intensive livestock farming. This matters for people with respiratory problems and for young children; ventilating on the quieter side of the home helps.
Average in Academiewijk: NO₂ 16,5, PM2.5 8,7 µg/m³.
Source and methodology
Annual average concentrations at 25 m resolution (RIVM, latest map). Marker on the bar: WHO guideline value (NO₂ 10, PM2.5 5, PM10 15 µg/m³); the colour shows the comparison with the WHO guideline and the EU limit for 2030.
Light at night
Very bright
darkvery bright
Average in Academiewijk: very bright.
Very bright: among the brightest 10% of places in the Netherlands, usually near greenhouses, industry, major roads or a city centre. Expect an orange night sky and a need for blackout curtains or blinds.
Source and methodology
Upward artificial light measured by satellites (RIVM light emission map 2023, 375 m grid), classified relative to all homes in the Netherlands: dark means the darkest 20%, very bright the brightest 10%.
Green space in the neighbourhood
31% green space within 500 m
Average in Academiewijk: 35%.
Little greenery: mostly paving and rooftops, with few gardens or trees. These neighbourhoods heat up more in summer and feel busier; adding greenery yourself, such as a planting strip along the front wall or trees, makes an immediate difference.
Source and methodology
Proportion of green space (grass, shrubs and trees) in the 500 m grid cell around this address (RIVM green space map 2022). Half of homes in the Netherlands have more than 52% green space within 500 m; one in ten has less than 32%.

As a rule of thumb, a passenger aircraft at an altitude of 1,000 m produces a peak outdoor noise level of around 60–65 dB (a loud conversation), rising to 75–80 dB at 300 m. Above 3,000 m, it blends into the background noise.
