When designing and building our Hostal/Homestay Un Mundo in Santa Catalina, Soná, Veraguas, Panama I had sustainability and environmental impact in the forefront of my mind.

| there’s only 1 world. we have only 1 planet to live on. we’re only 1 people. let’s all work together, not against each other! |
Hostalworld, which is one of the booking site on which we are listed, sent an email today encouraging their partners to think more about these topics. The recommendations they gave are good, yet only a small part of what we tried to do here. I thought I write a little bit about these topics various ways we made sustainability and impact a driving and deciding factor…
They also did some research comparing hostals with hotels, and found, based on their estimates, that hotels have 4 times as much of a negative impact. This report can be found here. The exact number, of course, is dependent on the quality of the estimates. But, it’s pretty obvious that if the average persons per room (and bathroom) is higher, the per bed amount of material and energy used for construction is smaller, and operations and maintenance of that space is less involved as well.
In our case, though, we applied a building style and used materials during construction that have a much better sustainability score than the typical or average construction.
Here some aspects:
* We don’t use concrete walls, but wood - concrete is a very strong CO2 source. Also, concrete soaks up the heat of the sun, turning rooms into baking ovens. Wood, on the other hand, acts as an insulation!
* Our walls are not solid, but are mostly thin lattice with quite wide gaps. There’s always a breeze in the room. And the cool night air can easily enter the room. To protect against mosquitoes we wrapped the whole house in insect screens.
* Roofs in Panama are mostly made of sheet metal. Ever touched some metal that was laying in the sun for a while? It gets very quickly very hot! If the roof touches the concrete all that heat gets absorbed and stored by the concrete. We have the roof far removed from concrete. Although the mansard apartment gets very hot during the day, by 18:00 it’s already cooled down enough to be comfortable again. And during the night I need a sheet to cover because it’s too cold without it!
* Our wood was resourced at the closest sawmill, which gets its wood from the forest behind their house. With that the transportation distances for the wood was minimal.

* We use only local wood (except the doors, which are prefabricated, made of pine, and transported). For walls that can get wet from the rain we use teak. For other purposes we used whatever type the sawmill had available that day.
* While we bought lots of normal boards, too, we also used many “chapones” - these are the first pieces of wood sawed off a log. They are rounded and with bark. Usually, these boards are discarded. We removed the bark, and cut lattice from them, with which we built the side walls. That wood, thus, is not rotting putting the carbon in the form of CO2 back into the atmosphere, instead the carbon stays bound as wood in our walls.
* Virtually all other hotels and hostals in the area need air conditioning to achieve a comfortable sleeping environment. We don’t need a/c - thus, our electricity bill is around 40$/month, instead of 300$ or more.
* The high humidity in the air causes mold and mildew, if there’s no air is not moving. Usually, people fight this by using harsh chemicals frequently on all surfaces. By having a very airy wall design, the air is always moving, so we do not need to apply such chemicals - which is healthier for the inhabitants and better for the environment, too.
