A concept in the University Master Plan 2008 is creating “dream urban university” that is “A Promise Place to Live and Learn with Nature” by creating a suitable environment for living and studying in an environment conducing to learning with physical characteristics that harmoniously respond social and environmental conditions. A university is like the second home, and is a spiritual center for all Mahidol members. There are three factors for such development including social, physical, and environmental developments.
1. Promote more resources efficiency utilization
2. Promote low carbon society
3. Promote community engagement
The key principles are using natural resources for maximum efficiency and benefits, focusing on resources usage reduction, and being low-carbon society while connecting with co-operating communities sustainably.
At the present, the university is taking an action on becoming a sustainable university by driving the Mahidol University Sustainability Action according to the 17 Sustainable Development Goals (17 SDGs) which is a framework of global development in the United Nations general assembly, to together achieve goals of sustainable social development, economic, and environment.
As Mahidol University, Salaya has a large number of flora species and water sources, there needs to be balance between conservation and development. There is, therefore, a clear designation of environmental conservation, green spaces, and development area by maintaining no less than 70 percent of spaces and green areas of the total area, according to the University Master Plan, to support green spaces environment and maintain prolific conservation areas full of species of plants. Original ecosystem if each area was maintained as much as possible, while green spaces in new areas were added by planting more trees, developing unused lands, building exterior, balconies, roof deck, and interior halls, horizontally or vertically. Adding green spaces is a policy of the university to promote sustainable physical development to create beautiful scenery, allow Mahidol members to have environmental awareness, decrease heat while add more fresh air, absorbing and filtering air pollution, and also create landmarks for the university. All of these are approaches to solving sustainable environmental problems.
A vertical green space or vertical garden is an art of organic architecture that could be with or without structure, and diversity of plants could be determined to suit characteristics, environment, and ecosystem of the building and its surroundings. According to types of equipment used, vertical gardens can be divided into the following 5 types.
is used with small to medium-size plants in fabric bags containing suitable soil, being attached to a wall. Geotextile fabric bags are popular as they are light-weight, able to preserve humidity well, water permeable, do not support growth of fungus, but support plants roots to attach to them.
looks like panel or tray with holes to contain soil for plants. Material used could be plastic or light-weight metal attaching on hanging frame or hanging wall for building decoration.
are frames to put in flowering pots that tilt and stack vertically without soil spilling. Any shape of pots with water drainage holes could be applied. Popular plants for this system are those that can grow to cover the pots. Popular watering system is setting drip irrigation system in every layer for regular dripping.
are concrete or clay walls with holes for plants to adhere to the structure or it could be built as a permanent wall with water dripping system through the block in each layer to feed them with water and nutrients. This system is popular for indoor plants such as golden pothos, hoya, dischidia, rhipsalis, and outdoor plants such as dragon’s tongue, red and green sissle joyweed, weeping willow, purple heart, etc.
can effectively prevent the heat from entering buildings by planting climbing plants in trays or other containers and let them climb on the wall or structure until it is full. Popular plants for this system are coat buttons, skyflower, Javanese treebine, easter lily vine, etc.
1. Adds more green space
2. Promotes environment, supports ecosystem, absorbs carbon dioxide – the main cause of global warming, and reduces pollution and some toxins
3. Reduces interior heat, saving energy
4. Gives relaxing view and creates aesthetic atmosphere to the area
5. Creates homes to small organisms such as insects
