Good Nature Hotel Kyoto.

Good Nature Hotel Kyoto holds WELL v1 at Gold, certified 6 August 2020 and recertified 6 August 2023. Every feature named here is a v1 precondition, mandatory for certification at any award level, so the certificate proves it. Air carries twelve preconditions. 01 Air quality standards is performance tested for volatile substances, particulate matter, inorganic gases and radon. 05 Air filtration, 06 Microbe and mold control and 12 Moisture management are all mandatory in v1, where WELL v2 leaves filter grade and mould control to optional features, so a v1 certificate says more about air than a v2 one at the same level. 03 Ventilation effectiveness and 02 Smoking ban complete the relevant ones. The certificate does not publish the readings, only that the building met the limits.

Good Nature Hotel Kyoto holds WELL v1 at Gold, certified 6 August 2020 and recertified 6 August 2023. Every feature named here is a v1 precondition, mandatory for certification at any award level, so the certificate proves it. Water carries five preconditions, all of them testing: 30 Fundamental water quality, 31 Inorganic contaminants, 32 Organic contaminants, 33 Agricultural contaminants and 34 Public water additives. Four named contaminant classes is a wider mandatory panel than WELL v2 requires. Periodic retesting and treatment are optimizations, so this attests to a test rather than to an ongoing regime, and no result is published.

Good Nature Hotel Kyoto holds WELL v1 at Gold, certified 6 August 2020 and recertified 6 August 2023. Every feature named here is a v1 precondition, mandatory for certification at any award level, so the certificate proves it. Light carries four preconditions: 53 Visual lighting design, 54 Circadian lighting design, 55 Electric light glare control and 56 Solar glare control. Circadian lighting design is mandatory in v1, where in WELL v2 circadian performance is optional, so this certificate establishes something about the light after dark that most certified hotels on this index cannot show. No colour temperature or melanopic figure is published with it.

Good Nature Hotel Kyoto holds WELL v1 at Gold, certified 6 August 2020 and recertified 6 August 2023. Every feature named here is a v1 precondition, mandatory for certification at any award level, so the certificate proves it. Materials sit inside the Air concept in v1. Three preconditions apply: 04 VOC reduction, covering interior paints, coatings, adhesives, sealants, flooring and insulation; 11 Fundamental material safety, restricting legacy hazards; and 09 Cleaning protocol with 10 Pesticide management, which govern what is applied to surfaces afterwards. v1 sets no criterion on mattress composition, linen fibre content, or textile certification such as GOTS or OEKO-TEX.

Good Nature Hotel Kyoto holds WELL v1 at Gold, certified 6 August 2020 and recertified 6 August 2023. Every feature named here is a v1 precondition, mandatory for certification at any award level, so the certificate proves it. Nourishment carries eight preconditions: 38 Fruits and vegetables, 39 Processed foods, 40 Food allergies, 41 Hand washing, 42 Food contamination, 43 Artificial ingredients, 44 Nutritional information and 45 Food advertising. Artificial ingredients being mandatory is stronger than WELL v2, which leaves that to an optimization. Safe food preparation materials and responsible food production are optimizations, so the certificate says nothing about cookware, cooking oils or sourcing.

Good Nature Hotel Kyoto holds WELL v1 at Gold, certified 6 August 2020 and recertified 6 August 2023. Every feature named here is a v1 precondition, mandatory for certification at any award level, so the certificate proves it. Two of Mind's five preconditions read onto this: 87 Beauty and design I, and 88 Biophilia I, qualitative, which requires a design incorporating nature through environmental elements, lighting and layout. The quantitative biophilia feature, with its area and frequency thresholds, is an optimization, so the certificate establishes that nature was designed in rather than how much of it there is.

Good Nature Hotel Kyoto holds WELL v1 at Gold, certified 6 August 2020 and recertified 6 August 2023. Every feature named here is a v1 precondition, mandatory for certification at any award level, so the certificate proves it. Two of Comfort's five preconditions are acoustic and both carry numeric limits: 74 Exterior noise intrusion and 75 Internally generated noise. That is stronger than WELL v2, where measured background noise is an optimization and only sound mapping is mandatory. Reverberation time, sound masking and sound barriers remain optimizations, and 77 Olfactory comfort is an optimization, so the certificate says nothing about scent.
