Vertical Gardens and Sustainable Building

Vertical Gardens

At Palo Santo Hotel, we are proud of being the first urban green hotel in Latin America. Our environmental commitment visually translates into a unique green architecture. Over 800 plants cover our façades, balconies, roof and patios, creating a one-of-a-kind vegetal structure. But, why exactly does this abundance of plants contribute to our green program?

Vertical gardens regulate inside temperatures

Hotel Verde

Plants help regulate temperatures inside the building, thus allowing to reduce energy consumption for heating and air conditioning.

Increased humidity brought by the vegetation significantly freshens the walls in summer. The gardens also provide a natural shade. Both effects considerably reduce inside temperatures during the warmest month. In Buenos Aires, where temperatures in summer often go beyond 90 ºF, it directly translates into large energy savings.

In winter, plants also bring a natural insulation. They protect the building from strong winds and create a more pleasant microclimate.

Plants absorb carbon dioxide emissions

Green Building

When plants grow, they absorb a significant volume of carbon dioxide. Estimates show that a small to medium-size plant like those growing on our walls capture about 3 kilograms of CO2 per year. Palo Santo Hotel is covered with over 800 plants, which translates into 2.5 tons of carbon dioxide absorption per year.

Vegetation and rainwater regulation

Vertical Gardens and Rainwater Absorbtion

In large cities such as Buenos Aires, most of the surface is covered with tarmac or constructions. There are no natural means of water absorption: rainwater goes directly to the city storm sewers. Buenos Aires suffers from sporadic yet very intense rain showers that regularly saturate the storm drains system. It results in temporary floods and difficulties to move around the city.

Plants naturally defer rainwater release to the sewers system. Rainwater is absorbed and only the surplus is gradually released. In addition to our plants, we also use a water tank that serves the same purpose.
