- Label spirit

True Cleanliness Should Not Only Be Seen.
It Must Also Be Explained and Measured.

The Clean Label begins with what people actually encounter while using a space. Through appropriate testing methods, clearly defined assessment criteria, and continuous quality management, it makes environmental information about air and water understandable, accessible, and traceable.

- Our approach

A Label Represents More Than a Result. It Also Reflects the Method and Principles Behind That Result.

Environmental quality cannot be assessed solely through appearance, odour, or a single number. The same space may present different conditions depending on occupancy, ventilation, fit-outs, equipment, water-storage tanks, pipework, seasons, and everyday operations.

For this reason, the Clean Label considers more than whether one test has been passed. It also considers whether the testing scope is clear, whether the methods are appropriate, how the data are interpreted, and whether the results are explained within the correct conditions.

Together, these principles form the spirit of the Clean Label and guide how environmental quality is understood, assessed, and communicated to the public.

A credible label should not only tell people the result. It should also explain where the result came from, where it applies, and how it should be understood.

-Actual exposure

Beginning with the Air People Breathe and the Water They Actually Use

Environmental quality is not an abstract building condition. It is the air people breathe every day, the water they come into contact with or use, and the environmental conditions they actually experience while spending time in a space.

Even when a building meets relevant requirements during design or upon completion, its conditions may still be affected after occupancy by human activity, ventilation, equipment, fit-outs, cleaning, water storage, and pipework systems.

The Clean Label therefore begins with how a space is actually being used. It focuses on real exposure within the certification scope, rather than relying only on building appearance, design documents, or data collected at the building entry point.

What We Focus On

  • The indoor air people actually breathe

  • Point-of-use water that people actually come into contact with or use

  • Environmental differences created by different uses of a space

  • Environmental conditions that may affect children, older people, and other sensitive groups

  • The effect of everyday space management on quality conditions

The focus of testing is not an abstract building, but what people actually encounter within the space.

- Continuous management

Environmental Conditions Change, So Quality Management Must Continue

Air and water quality do not remain permanently unchanged after a single test. Occupancy, ventilation practices, finishing materials, cleaning activities, equipment condition, water-storage tanks, pipework, seasons, and operating conditions can all cause environmental data to change.

The Clean Label promotes more than a one-time photograph, inspection, or declaration. It promotes a quality-management approach supported by standards, records, interpretation, retesting, and improvement. A single test presents conditions at a specific time and under specific circumstances; subsequent records and retesting help determine whether the space has changed and whether further management or improvement is needed.

→ 01

Define the Scope

Specify the space, parameters, and testing conditions.

→ 02

Maintain Records

Retain testing information that can be consulted.

→ 03

Interpret Changes

Understand anomalies, differences, and their potential effects.

→ 04

Retest as Required

Conduct follow-up verification in accordance with scheme requirements.

→ 05

Track Improvements

Take action when necessary and continue to verify the outcome.

Just as health management depends on periodic monitoring, the quality of a space should not rely on a single inspection.

Actual retesting cycles and follow-up requirements are governed by the officially issued certification criteria and certification documents.

- Scientific methods

Different Quality Parameters Require Different Testing Methods

Environmental quality encompasses pollutants and quality indicators with different characteristics. It cannot be summarised using a single device or number.

Some parameters can be measured immediately on site. Others require sampling, culture, or sample preparation, while some must be analysed by a laboratory with the appropriate technical capability.

The Clean Label selects corresponding sampling, measurement, and analytical methods according to the characteristics of each parameter, the conditions of the space, and applicable requirements. Equipment calibration, sampling location, and data representativeness are also considered when results are interpreted.

01

On-site Measurement

Suitable for observing environmental conditions at a specific time and location or for understanding trends in measured values.


02

Sampling and Analysis

Samples are collected using appropriate methods and then cultured, prepared, or analysed according to the requirements of each parameter.


03

Laboratory Testing

Parameters requiring specialised equipment and analytical capability are tested by laboratories with the appropriate competence.


Important Notice

Sensors can provide trend information, but sensor readings do not constitute a complete certification result. Device drift, calibration, installation location, and sampling representativeness still require appropriate management and interpretation.

04


- Standards & sources

Different Sources Serve Different Purposes and Should Not Be Treated as Equivalent

The Clean Label gives priority to local laws, requirements of competent authorities, and applicable mandatory provisions. Where appropriate, it may also refer to international health guidelines, indoor-air measurement methods, drinking-water safety guidance, building-ventilation standards, and other publicly available technical references.

Regulations, certification standards, health guidelines, and method standards differ in legal status and intended use. Reference to international material does not automatically make it a statutory limit in the local jurisdiction, and a health guideline should not be described directly as a certification pass criterion.

The website should clearly identify the title, issuing body, version, applicable jurisdiction, source type, and update date of each reference, helping users understand the role that each source plays.

01

Laws and Requirements of Competent Authorities

Requirements that have legal effect in the applicable jurisdiction or must be followed by law.

02

Certification Standards and Certification Criteria

Define the Clean Label’s certification scope, process, assessment, and management requirements.

03

Health and Environmental Guidelines

Provide reference directions for health protection or environmental quality but may not be legally binding.

04

Testing and Method Standards

Describe technical methods for sampling, measurement, analysis, equipment, or quality control.

05


- Responsible communication|負責任溝通

Explain the Results Clearly—and Explain Their Boundaries Just as Clearly

Meeting the relevant assessment requirements does not mean that every pollutant is entirely absent, nor does it constitute a guarantee of permanent safety or individual health.

Every test result corresponds to a defined space, parameter, method, condition, and time. Outside these boundaries, the result should not be extended to untested areas, pollutants that were not included, or all future periods.

The value of the Clean Label lies in completing an assessment within a clearly defined scope and against applicable standards, then explaining the results in an accessible and understandable way—not in using absolute language to create an unrealistic sense of security.

PUBLIC PRINCIPLE 01

Explain What Was Tested

Clearly identify the testing parameters and certification scope. Do not use a limited result to represent the entire space.

PUBLIC PRINCIPLE 02

Identify the Basis and Date

Identify the standards used for assessment and the dates applicable to the testing, certification, or updated information.

PUBLIC PRINCIPLE 03

Explain the Limitations of the Result

Do not use absolute statements such as “zero pollution,” “absolute safety,” “permanently valid,” or similar claims.

Take environmental risks seriously without replacing professional interpretation with exaggerated language.

- From principle to practice

Five Principles Put into Practice Through Four Verifiable Actions


01

Clear Scope

Explain the premises, areas, testing content, and applicable conditions covered by the label.

02

Appropriate Methods

Select suitable on-site measurement, sampling, or laboratory-analysis methods according to the testing parameter.

03

Traceable Basis

Identify the regulations, standards, technical methods, issuing bodies, and document versions used.

04

Results That Support Continuous Management

Use records, retesting, anomaly interpretation, and improvement tracking to understand changes in the quality of a space.


The Clean Label does not treat a one-time declaration as the endpoint. It seeks to establish a shared language through which environmental quality can be tested, explained, tracked, and continuously improved.
