In su-re.co, we work in a holistic way that reflects our concern towards the environment and climate change. Using too much electricity, especially if it is not derived from the renewable energy, is obviously something we are trying to avoid. Somehow some of our issues need instant solutions, but not all of them are sustainable enough. One of our problems in the office is the moisture control that attracts fungus and termites and produces odour. Therefore, we decided to build a ventilation system under the wooden floor to avoid moisture and fungus development.
Our office is a traditional Javanese building, mainly composed of wood. Since we are located around the equator and very close to the sea, the climate here is particularly humid. The average yearly temperature in Bali is 26° Celsius, with a relatively higher average humidity. In our case, the building floor is close to the ground, so we have observed the development of moisture and termites. For a wooden house with completed construction, it is possible to add ventilation under the floor to fix the problem. However, we need to consider various aspects of building the whole system to adjust with the existing building such as construction type, air-conditioner performance, indoor and outdoor space, and heat exchange.
Overall, this is how the airflow is designed to go through the pipeline to ease the air circulation system. This design was chosen as this does not interfere with the existing building and does not take up much space. The airflow system is also designed to obtain the solar heat to accelerate the air circulation system.
To make the whole system more effective and accelerated, we installed an extra blower system under the ground. It is useful to reduce the humidity to the most optimum level as possible to avoid termite attack to the office. The blower that we installed is based on Shiroko system, which produces less noise and has more energy efficiency, which means electricity need is relatively lower using this system.
We do not stop here. We still seek for more opportunities to bring more innovations for the more sustainable system for better air circulation in our office.
We found it quite problematic to keep standing water clean, especially with temperatures and air quality like those in Bali. It became a reason why it is extremely important to have the rainwater filtered before flowing it into the tank. It needs different levels of filtration to obtain stored clean water. This water will have to be drinkable as much as possible and at least clean enough for showering or brushing teeth.
Indeed, since the available space is limited, a model with a higher proportion between height and wide could be the best compromise. The most common and suitable for the location is the cylindrical shape. Besides that, the cylinder shape has a higher capacity to contain the pressures strengths due to the considerable water volume that will fill inside. Moreover, the round shape of the top part avoids stagnant water formation keep the top of the tank clean automatically.
Even though this project still needs some evaluations and further experiments, this project is a great initiation for better water availability in our office.
