Shade, Water and Seating: How Basic Comfort Increases Footfall

Why basic comfort is a business problem, not an aesthetic one

Every city has a plaza that is beautiful on a drawing board but empty in August. The explanation is rarely design quality — it is basic physical comfort. Project for Public Spaces, which has evaluated thousands of public places worldwide, defines comfort as one of four essential qualities of a successful space, alongside access, uses, and sociability. Comfort includes safety perception, cleanliness, and a factor the organisation singles out as chronically underrated: availability and variety of seating.

The physiological mechanism is now backed by quantitative evidence. A 2025 study of five parks in Tucson, Arizona — where summer highs reach 37–43°C — combined thermal sensors, infrared surface-temperature cameras and systematic behavioural observation using the SOPARC tool. The authors found a consistent negative association between relative surface temperature and park visits in all seasons (coefficient −0.02, p < 0.001). Zones with shade structures — ramadas, pavilions, dense canopies — received significantly more visits than uncovered areas, even after controlling for park type and accessibility.

For facility managers and city administrators the implication is direct: comfort is quantifiable, and it predicts visitor behaviour better than architectural merit alone. A surface that burns through thin shoes will repel visitors regardless of the beauty of surrounding plantings.

• Comfort is a measurable variable, not a subjective preference
• Surface temperature predicts visit counts independently of other park features
• Seating choice — sun or shade — is a quality marker managers can audit

Shade: the most powerful single metric in hot climates

In hot regions, shade functions as a currency. A Japanese study of bench users in Osaka's Hamadera Park measured Wet Bulb Globe Temperature alongside seating choices. The authors found that for every one-degree rise in WBGT, the proportion of people deliberately choosing shaded benches increased by about ten percent. Their recommendation: aim for a ratio of roughly 87.5 percent shaded benches to 12.5 percent sun-exposed ones — not because every seat must be dark, but because unshaded seats sit empty during peak hours and waste space.

Shade can be delivered in many ways, with very different cost curves. Trees offer the best long-term value: they cool the air through evapotranspiration, not merely by blocking radiation, and they appreciate over decades. But they take years to mature. Shade sails, ramadas and green pergolas deliver immediate effect at higher upfront cost and ongoing maintenance liabilities. A mixed strategy is typical: trees along main paths, tensile structures over seating clusters, and adjacent buildings' arcades as free marginal shade.

Time-of-day modelling matters. An east-facing wall may provide relief at noon but leave a bench exposed at 16:00, precisely when families arrive. Climate-sensitive street design work in New York's High Line demonstrated that pedestrian activity exhibits quantifiable thermal breakpoints: once a threshold of heat exposure is crossed, people abandon open zones and concentrate in shaded micro-environments. Managers should map shade by hour, not by annual average, and adjust furniture or plantings to cover the patterns observed.

• A 1°C rise in heat stress increases shade preference by about 10% (Osaka evidence)
• Trees cool through evapotranspiration, not just by blocking sun
• Design shade for the hours people actually arrive — not for the noon average

Water: from drinking fountain to family magnet

Water serves two separate roles in public spaces — utility (drinking, cooling) and attraction (splash pads, fountains, misting). The utility function is severely under-invested. A 2026 review by the Public Health Communication Centre in New Zealand synthesised five studies from 2014–2018 showing that only 19–20 percent of parks and children's playgrounds had any drinking fountain. A targeted public-health campaign in the Taranaki region — local data plus media advocacy — was followed by a 2.1-fold increase in fountains, from 25 to 52 across three councils, at a cost of roughly NZ$6,500 per unit.

Drinking fountains remove the most ordinary barrier to long visits on a hot day: thirst. Research on park-based physical activity shows that access to free water is a precondition for sustained exercise, particularly among children and older adults. A University of Otago study of Wellington playgrounds found that only 6 percent had working fountains within 100 metres — and noted that fountains near splash areas convert short cooling visits into two-hour stays.

The attraction function — splash pads, interactive fountains — drives visitation in a different way. A peer-reviewed experiment using photo-realistic simulations of plazas found that adding a water fountain and storefronts significantly increased rated 'visitability'; the effect was strongest for adults aged 25–44, while floor-fountains scored lower with both younger (18–24) and older (45+) participants. For operators, the practical lesson is to offer water at different scales: bottle-filling stations for joggers, small basin-level elements for toddlers, and one signature fountain for identity.

• Only 1 in 5 studied parks had drinking fountains; targeted campaigns can double provision
• Water elements appeal unevenly across age groups — design for segments, not averages
• A bottle-filler plus splash pad can convert a transit stop into a two-hour stay

Seating: the silent lever on dwell time and economics

Seating is the most direct instrument a manager has to convert walking people into staying people. Project for Public Spaces states that "the importance of giving people the choice to sit where they want is generally underestimated." The evidence supports this. Stated-preference research on urban spaces found that increasing the seat-to-area ratio raises both intended stay duration and stated willingness to pay for the experience.

Real-world interventions confirm the mechanism. Arup's FitzPark — a temporary parklet in central London with new seating, planting and improved walkability — was evaluated before and after with structured surveys. Results showed a 23 percent increase in street users, a 41 percent rise in self-reported wellbeing among visitors, and 100 percent support from local businesses. In Copenhagen, Gehl's multi-method evaluation of Town Hall Square documented a 120 percent increase in people present after the site became genuinely comfortable for lingering.

Configuration matters as much as quantity. Field experiments in a compact Japanese city during summer festivals tested multiple bench layouts. A single row of chairs connected by tables produced consistently longer dwell times than all alternatives — the layout allowed groups to face activity while maintaining personal space. Comfort is also physical: materials that absorb heat (dark metal) repel users, while timber and stone remain usable; back support increases sitting duration; distance between adjacent groups must preserve personal comfort zones.

• Seating ratio predicts both dwell time and willingness to pay
• FitzPark: +23% users, +41% wellbeing, 100% business support — from a temporary parklet
• Layout of chairs and tables affects behaviour more than the headline number of seats

The economics of comfort: from footfall to retail value

The connection between physical comfort and commercial performance is visible in major redevelopment cases. When New York's Times Square was partially converted from road space to pedestrian plazas with seating, trees and tables, daily pedestrian volumes rose from roughly 356,000 in 2008 to 482,000 in 2013 — a 23 percent increase. Retail rental values in the district more than doubled over the same period. Multiple simultaneous factors were at play, but designers and economists point to the physical transformation as the enabling condition: the same tourism growth would not have produced equivalent retail value if people had nowhere comfortable to stand.

The causal chain runs: comfort → dwell time → spending. Visitors who sit for ten minutes spend differently from those who pass for thirty seconds. The Copenhagen Town Hall Square data explains why: new metro connections brought people to the area, but the 120 percent increase in people present (not merely passing) was achieved because the redesigned square offered shade, water, seating and activity throughout the day.

For a facility manager, the practical metric is not 'total visitors' but 'people present per square metre per hour' and 'average dwell time'. Track these two numbers before and after adding shade structures, benches or a drinking fountain. Gehl's methodology — observational counts combined with sensor data — is now used routinely in Copenhagen and elsewhere to identify zones where comfort interventions will produce the highest return on investment.

• Comfort converts transit flows into staying flows; only staying flows generate retail value
• Track dwell time and presence per square metre, not raw gate counts
• Times Square: +23% pedestrian volume accompanied by 2x+ retail rents (multi-factor effect)

Where to start: a five-step action plan for managers

Step one — audit during peak heat. Visit the space on the year's hottest clear day between 12:00 and 16:00. Map where people sit, stand and walk; note where the space is empty. Measure surface temperature of key materials with a non-contact thermometer. Any zone above roughly 50°C surface temperature will be deserted in summer.

Step two — prioritise by cost-per-visitor-impact. The cheapest intervention is repositioning existing benches into shade or adding a few mobile chairs; cost is negligible and it can happen within a day. Next is a drinking fountain at US$3,000–8,000 installed, with verified public-health justification. Most expensive is new shade infrastructure: trees take years, while sails cost $5,000–20,000 per cluster. Do the cheap moves first while budgeting the slow ones.

Step three — design for choice, not uniformity. Provide fully shaded, lightly shaded and open sunny seating. Mix bench types: backs for older users, flat ledges for lounging, individual chairs for flexible groups. Place seating near activity edges and facing flow paths. Keep at least one seat orientation that permits people-watching.

Step four — measure before and after. Establish baseline counts for one week before intervention: total flow, dwell time, proportion stopping versus passing, gender balance. Repeat at one month and three months post-intervention. Without a baseline, no impact claim can be defended to funders or politicians.

Step five — budget maintenance from day one. Shade sails need annual replacement or re-tensioning; drinking fountains need nozzle cleaning and winterisation; wooden benches require re-oiling. Industry practice suggests allocating 5–10 percent of capital cost per year for upkeep. An unmaintained fountain is worse than no fountain, because it signals neglect and breeds distrust.

• Run the audit on the hottest, clearest day — that is your worst-case scenario
• Sequence: reposition benches (free) → add fountain ($5k) → plan trees (slow)
• Dwell time and demonstration data make your budget case to councils and BIDs
