4.5 Maintenance
For the G‐SEED maintenance category, we believe that health‐friendly buildings can be achieved
by preventing discoloration and contamination of materials through duct protection, filter replacement,
and moisture absorption management during construction.
4.6 Natural Environment
In this category, we believe it is necessary to distinguish between the standards for assessment of
the natural environment, such as green land formation, natural ground green rate, and biotop
formation without modifying the standards for improving health. The use of health‐friendly
technologies can simultaneously preserve the natural environment and help humans to increase their
psychological sense of well‐being that results from contact with nature.
4.7 Indoor Environment
Table 1 compares the G‐SEED standards to the WELL building standards as they relate to human
health systems. The analysis focuses on non‐residential projects. For standard 7.1 ‐ Application of
Indoor Air Pollutants Low Emission Products, it seems to consider the transition from the method for
evaluating the use of certified materials to the assessment of whether the level of indoor air pollutants
exceeds acceptable levels. Additional standards and measures such as high‐efficiency air filtration
systems and real time monitoring systems for PM10 and PM2.5 should be considered to protect the
health of building users from particulate matter. For noise reduction, exterior noise intrusion from
vehicle traffic or internally generated noise from mechanical equipment, on‐site performance tests
should be employed. Exterior sound pressure levels can be measured in decibels (DB)and noise criteria
(NC) for sound pressure limits of the octave band spectra ranging from 63 Hz to 8,000 Hz could be used
for mechanical equipment.
5. Results and discussion
It looks that G‐SEED is encouragement system to provide opportunities for physical activity or
spaces that enhance human health. It is likely that high level of G‐SEED has a more holistic knowledge
of the impact of buildings on the health of their occupants. Implementing and maintaining healthy
techniques seems to require the introduction of a policy system that can effectively maintain and utilize
the health building technologies applied to the building in the operational stage.
