Workplace Health & Wellbeing Matrix™

This matrix compares workplace environments according to the opportunities they provide for interaction with daylight, fresh air, vegetation, natural views, outdoor access and restorative environmental exposure during the working day. It evaluates environmental opportunity rather than occupation, income, productivity or job satisfaction.

Purpose

The Workplace Health & Wellbeing Matrix™ provides a standardised framework for comparing workplace environments using the NRE Environmental Interaction Classification. It helps identify practical opportunities to increase healthy environmental exposure before work, during breaks and after work without changing occupation.

Scope

This matrix applies to general workplace environments including offices, commercial premises, industrial facilities, retail workplaces, public-sector workplaces and comparable employment settings. Occupation-specific matrices, including Night Shift, Healthcare Workers and Outdoor Workers, are addressed separately.

Standardised conditions

Unless otherwise stated, classifications assume:

• ordinary daytime employment
• lawful workplace access
• normal weather conditions
• routine break periods
• standard workplace safety procedures
• no emergency or abnormal operational conditions

Environmental opportunities may vary according to building design, local climate, employer policies, available outdoor areas, working hours and individual job responsibilities without changing the underlying environmental classification.

Important methodological boundary

This matrix does not measure job quality, salary, prestige, workload, productivity or employee satisfaction. Classification is based solely on the quality and accessibility of environmental interaction available to workers. A highly paid occupation in a windowless office may provide lower environmental opportunity than a modest workplace with frequent access to daylight, fresh air and natural surroundings.

Workplace Health & Wellbeing Matrix™

Workplaces are classified according to the quality, accessibility and continuity of environmental interaction available during the working day. Salary, occupation, building prestige, productivity and workplace popularity do not determine the grade.

General classification methodology

Workplaces are graded according to the environmental opportunity available during the working day, including authorised access before work, during breaks and immediately after work. The grade concerns the environment rather than the employment conditions or clothing choice.

  • Natural daylight
  • Fresh-air exposure
  • Natural views
  • Indoor vegetation
  • Accessible outdoor break areas
  • Mature tree canopy
  • Shade and thermal comfort
  • Walking routes
  • Water and biodiversity
  • Separation from traffic
  • Noise and mechanical disturbance
  • Continuity of environmental access
  • Frequency of practical access
  • Clothing and footwear as secondary conditions only

Protective clothing, uniforms and personal protective equipment do not reduce the environmental class where they are required for safety. Likewise, lighter or reduced clothing does not independently increase the class.

Quality-assurance review: Every Class D and E classification was challenged before publication. Outdoor work was not automatically rated highly because paved, industrial or traffic-dominated outdoor environments may provide only moderate interaction. Class E is restricted to an unusually integrated workplace campus combining multiple mature natural systems, extensive accessible routes and sustained environmental continuity that clearly exceeds an ordinary landscaped workplace.

How to read the Workplace Matrix

The matrix compares environmental interaction available within different workplace settings. It does not rank employers, occupations, income, productivity, employee satisfaction or professional status.

Read across each row

Each row represents one workplace environment. Reading across shows whether clothing conditions or authorised outdoor access meaningfully change interaction with daylight, airflow, vegetation, natural views or nearby outdoor space.

Read down each column

Reading down one column compares workplaces under approximately the same clothing or access condition. This keeps the environmental setting separate from occupation and dress requirements.

Practical access matters

A park beside a workplace only contributes strongly where workers can realistically access it before work, during authorised breaks or immediately after work. Nearby nature that cannot be reached provides a weaker practical opportunity.

Restrictions remain separate

Red notices identify workplace, safety, hygiene, legal and operational restrictions. They do not replace the environmental grade or convert the matrix into an employment or occupational-risk assessment.

Class A: Very limited The workplace provides little or no meaningful access to natural daylight, fresh air, vegetation, natural views or outdoor space during the working day.
Class B: Limited Some daylight, exterior views or brief outdoor contact is available, but the environment remains substantially enclosed, artificial or difficult to access.
Class C: Moderate Good daylight, planting, natural views, courtyards or regular outdoor exposure provide a useful but incomplete range of environmental interaction.
Class D: High Workers have practical and sustained access to mature vegetation, shaded routes, fresh air, outdoor seating or nearby parkland during the workday.
Class E: Exceptional An unusually rich and accessible workplace landscape combines multiple mature natural systems, long connected routes and minimal built disturbance in a way that clearly exceeds Class D.

Factors affecting classification

Grades reflect the combined quality, directness, frequency, duration and practical accessibility of environmental interaction. No single design feature or workplace benefit independently determines the classification.

  • Natural daylight at the work area
  • Fresh-air access
  • Natural views
  • Indoor vegetation
  • Windows that can be opened where appropriate
  • Accessible courtyards or terraces
  • Outdoor break areas
  • Mature tree canopy
  • Shade and thermal comfort
  • Walking routes
  • Water and biodiversity
  • Separation from traffic and machinery
  • Noise and air-quality conditions
  • Frequency of practical access
  • Duration of authorised access
  • Continuity between indoor and outdoor areas
  • Operational restrictions
  • Clothing as a secondary condition only

Employer prestige, building cost, salary, job title, landscaping expenditure and the number of workplace amenities are not environmental grading criteria. A prestigious workplace may remain Class A or B, while a modest workplace with direct access to mature vegetation may reach Class C or D.

Suggested progression

Progression is optional and should remain compatible with workplace duties, break entitlements, safety requirements, accessibility and individual health needs. It does not require changing occupation or reducing protective clothing.

Begin with daylight awareness

Identify whether your usual work area provides natural light or an exterior view. Where possible, use a lawful position that improves daylight exposure without disrupting duties.

Use available natural views

During brief pauses, look toward trees, sky, water or distant landscape where available rather than remaining focused continuously on artificial surfaces.

Improve the immediate work area

Where authorised, introduce suitable indoor planting or natural materials. These may improve environmental quality but do not replace outdoor access.

Use authorised outdoor breaks

Spend part of an existing break outside where a safe, lawful and practical area is available. Even a courtyard or shaded terrace may broaden environmental interaction.

Choose the greener route

Where practical, use a route to parking, public transport, amenities or another work area that includes daylight, trees or open air rather than remaining indoors throughout the day.

Walk during part of a break

Use an authorised path, courtyard or nearby public area for a short walk while remaining within break limits and personal capacity.

Use nearby parkland

Where time and access allow, use an adjoining park, greenway or landscaped campus before work, during a longer break or immediately after work.

Extend environmental continuity

Link workplace exposure with the journey to and from work by choosing shaded walking routes, outdoor waiting areas or green transport connections where practical.

Dress appropriately for the workplace

Wear clothing and protective equipment appropriate to your duties, workplace policies and environmental conditions. Environmental interaction should be increased through better access to nature rather than by reducing necessary clothing.

Seek stronger environmental access

Where workers, employers or facility managers are considering improvements, prioritise shade, usable outdoor areas, mature vegetation and practical access rather than decorative features alone.

Workplace environmental interaction does not require reduced clothing

Workers wearing standard uniforms, protective equipment or full work clothing can receive the strongest environmental opportunity available within a well-designed workplace. Higher classification comes from daylight, fresh air, mature vegetation, practical outdoor access and environmental continuity, not greater bodily exposure.
