Evidence by area
All eight areas, in the order this index reads them. Every line was read and placed by a person.
Air Ecology
The cooling strategy is published as a material one: local brick with a pale surface that reflects sunlight, used so rooms stay cool without air conditioning. No air change rate or reading is published.
In their words: “The volumes are constructed of local bricks – a material that helps keep interior rooms cool without the use of air conditioning. The bricks have a pale yellow hue that reflects sunlight and further aids in cooling.”

The architect describes the interiors as naturally ventilated, cooled by the thermal mass of the brick walls and ceilings, with the buildings sited to take the ocean breeze and offshore winds.
In their words: “More pragmatically, the thermal mass of the brick walls and ceilings help cool the naturally ventilated interiors.”
A third party publisher records the vault-and-arch construction as a passive cooling system that keeps rooms temperate without heavy air conditioning, with no ventilation figure given.
In their words: “Casona Sforza was designed by celebrated Mexican architect Alberto Kalach using ancient vault-and-arch construction in locally sourced brick, a passive cooling system that keeps rooms naturally temperate without heavy AC.”

Water Integrity
Wastewater is published as running through an activated charcoal treatment plant rather than septic tanks, with the stated reason of protecting the local aquifer. No volume or test result is published.
In their words: “Other sustainable features include a wastewater treatment plant operated with activated charcoal (in lieu of septic tanks that might damage the local aquifer)”
The circular pool at the centre of the hotel is published as salt chlorinated, which names the disinfection route. No residual level or water analysis is published.
In their words: “a long terrace and the brick barrel-vaulted roofs of guest suites intersect the salt-chlorinated pool's concentric circular forms”
Light Rhythm
Daylight and darkness in each suite are controlled by a named physical device: a custom wooden gate with small blinds on every archway, which shades the room without closing the view.
In their words: “A custom-made wooden gate is applied to each archway with small blinds that provide privacy without completely obscuring the view of the landscape, and that also allows air circulation to create a more pleasant climate inside each of the eleven rooms”

Suites are described as carrying clerestories above louvered doors, so daylight enters high in the vault. No colour temperature, lux level or blackout specification is published.
In their words: “The property's public spaces, at right, are completely open to the elements, while guest suites, behind, feature clerestories and louvered doors in Macuili and oak for privacy.”
EMF Harmony
Not published. We looked and found nothing on this, which is a gap in what we could read, not a finding about the building.
Materials and Textiles
The building material is named to its maker and its rule: sand-coloured bricks hand-crafted by local artisans, with synthetic products avoided wherever possible. No emissions class or finish chemistry is published.
In their words: “Hand-crafted by local artisans, the sandy-hued bricks represent the Casona's imperative to build with locally produced materials and avoid synthetic products wherever possible.”
Soft furnishings are named by craft and by place of making: rugs woven in Teotitlan del Valle, palm-leaf lamps from Veracruz, curtains, chairs and hammocks from the Yucatan.
In their words: “Rugs were woven in the small village of Teotitlán del Valle, and palm-leaf lamps came from the port city of Veracruz. Curtains, chairs and hammocks were fabricated in the Yucatán Peninsula.”

A third party publisher records the bathroom amenities as made in house by the Pueblo del Sol artisan community and the room textiles as raw linen and cotton.
In their words: “Organic bath products (honey soap, shampoo) are made in-house by the Pueblo del Sol indigenous artisan community, and raw linen and cotton textiles are in all rooms.”

The property states a sourcing rule for its furniture timber: no excessive logging, and wood taken from trees that have completed their natural cycle. No species or supplier is named.
In their words: “Following the statute of no excessive logging but rather using wood from trees that have completed their natural cycle.”
Food and Kitchen
Three kitchen ingredients are traced to a named growing project the hotel funds: honey, vanilla and coffee from Pueblo del Sol in the Oaxacan mountains.
In their words: “we use honey, vanilla, and coffee as ingredients grown in our sister project, Pueblo del Sol, in the Oaxacan mountains”
The fish handling method is named. Daily catch is dispatched by ikejime, and the produce is stated to be non-GMO and local. No grower, boat or certification is named.
In their words: “Daily fishing is carried out using the ikejime technique, promoting responsible and respectful fishing practices in the marine ecosystem.”
The kitchen is described as farm to table, drawing on the orchards of local producers who work seasonal and non-intensive harvest cycles, with no share of the menu quantified.
In their words: “Sforza House is committed to a culinary proposal based on the farm-to-table principle, guaranteeing the freshness of the ingredients of each dish, which come from the orchards of local producers that respect the seasonal and non-intensive harvest cycles.”

Biophilic and Healing Design
The siting rule is published as a number: less than 30 percent of the one-acre site was cleared, and the mangroves, oaks and cypress that were there were left standing.
In their words: “They cleared less than 30 percent of the natural landscape of mangroves, oaks, and cypress. "We sited the buildings to cause the least amount of intrusion and to take advantage of the views, ocean breezes, and offshore winds," notes Kalach”
The scheme is attributed to a named architect and studio, Alberto Kalach of Taller de Arquitectura X, and to a published form decision: ten brick vaults of varying height facing the Pacific, arranged around a circular pool.
In their words: “The resort consists of arched volumes of varying heights, which are arranged in an asymmetrical manner. The vaulted shape offers several benefits, including being able to withstand earthquakes and allowing positive energy to flow into the suites, the team said.”

The property states that only 30 percent of the land was built on and that the planted areas carry endemic vegetation, with the design described as following principles of bio-geometry.
In their words: “We have utilized only 30% of the land, allowing nature to retain its space. The design of our facilities is based on principles of bio-geometry, respecting the harmony between the built environment and the surrounding nature. Our green areas feature endemic vegetation, preserving local biodiversity.”

Disclosures
Compare what each stay offers, how it was checked and what still needs confirming. Assessment labels describe the review, not an overall quality rating.
A low score means a property has not published information. It does not mean the property is unsafe, unhealthy or poorly run.
A score describes proof: what a stay publishes and, on a Human Garage certified stay, what our assessor checked in person. It is not a quality rating of the property. Listings are free, and any commercial relationship is disclosed.
