Sustainable Urban Development in International Cities

Reshaping Mithi river, Mumbai

To learn about the complex interaction of key instruments, actors and procedures in urban sustainability planning in the city of Mumbai in India. Proposing a suitable future scenario based on the issues and the current state of the river as a group project.

The sections on the show the current and ideal states of the river. Current state of the river is extremely deteriorated and the water is far from being usable due to the constant misuse by the Dharavi slum area residents as a sewage. Similarly the industrial areas in Bandra-Kurla complex (see page 12) have been dumping industrial waste in the river.

Mithi river runs alongside the Chhatrapati Shivaji Maharaj International airport (CSMIA) which is still expanding as the requirement for runway length increases. The river runs through Dharavi (largest slum in India) that is treating the river as a domestic waste dumping site. BKC was developed on marshy land area that, once upon a time was a part of Mithi river bank that has poor surface drainage and the current drainage lines are crossing the river span in an unplanned way obstructing the flow of the water in the river.

A stretch of Mithi river flowing through various building typologies.

Neighbourhood Analysis and Urban Regeneration

Alsterdorf, Hamburg

Analysing the neighbourhood for weaknesses and potentials in urban regeneration specifically catering to access to allotment gardens (Kleingartenverein). Proposing a suitable scenario based on the findings to avail access to the allotment gardens.

The area holds a tremendous potential to develop a strong bicycle network as well. The open areas in the district are very well maintained and the prime reason behind it is that they are private. This shows an opportunity to create new open spaces that serve all the residents of the district and not just a focused group.

Proposal for allotment gardens: Creating more spaces accessible to everyone and not just the lease holders of the allotment gardens. Open space barbecues, community garden spaces, children’s play area were some of the ideas to create a more inclusive feeling. The design also lets people rent a bike close to the boat renting hub to have continuous flow of commute and have mobile pods as flexible spaces for multiple uses such as enjoying the river-front and community gardens in chilly winters and hot summers.

Mexico City has a climate that allows to solve cooling with natural ventilation systems. According to the monthly Diurnal Average, heating is only needed in the early mornings and late afternoons, because between 11:00 and 14:00 temperature is in the comfort zone. According to the sun path, the west side of the building will get higher sun exposure and temperature. Natural ventilation for cooling is strategically convenient from east to west, because the strongest winds come from this direction.

The sun rises at 90º in March and September reaching an altitude of 70º. Its minimum rise angle is 70º in December and 110º in June. This means that buildings have a strong direct sun angle in the afternoon creating overheat while in the morning they lack sunlight.

The values for global horizontal radiation indicate a high potential for PV harvest. Even in December there is over 100kWh/m2. This indicates that even in winter, pv panels can generate electricity for the building use.

These strategies are in favour of increasing the cross ventilation in small scale nonresidential buildings. For ample, addition of ceiling fans is a sensible solution for hot summer days. Although in the case of Mexico the heating demand of 463 hours should not be ignored. The guidelines suggested by software seem to focus on problems faced during winter days with lowest temperature and therefore still pose dependency on mechani cal heating. In addition, suggesting light weight construction (strategy 66) will not be a suitable preference construction.

The chosen design guidelines speak for both summer and winter seasons. They target to minimize internal heat gain and increase cross ventilation in summer months. They also advise to have tight interior planning to prevent temperature drop in winter months. Due to these guidelines, the human and overall adaptive comfort is achievable. With the help of these guidelines Mexico city has the potential to be independent from heavy mechanical ventilation.

On the other hand, they allow flexibility in planning of spaces and advise on designing a facade according to orientation of building. For example, strategy and also advise on percentage of glazing in a facade. The strategies should also suggest alternatives or other categories for construction material for subtropical climate.

COMMENTS

An important input from the software is related to the orientation of the building. The software guidelines right fully suggest that west facade has an vital role in ventilation and that it needs shading during summer. The facade can have a larger share of glazing to retain light in the morning hours when it is more needed according to the sun shading diagrams.

The optimal building distance calculated through excel was of 20 meters. Since the building has an elongated proportion, this distance to neighbouring buildings was adjusted in each of its sides. The shorter facades face each other at a distance of 10 meters, while on the longer sides, the distance of 20 meters remains. With this disposition, a better control of overshadowing is achieved.

Inspired by the concept of megablocks in Catalunya main vehicle streets are proposed between blocks, and between the grid of 9 buildings within the block, pedestrian streets can enhance better livability through frequent connections and less cars.

Project overview and stakeholders

The greatest assumptions of this project come from the legal, social, economic and technical perspective. For this reason it is understandable the importance of finding responses for each case, in order to guarantee its success. The first one is the community’s willingness to embrace such an idea and to actively participate. The preparation of the community with soft tools is something that should happen through the constituency and guidance of a neighborhood association or a cooperative.

Kindergarden School

By NGK Studio, Pune

This is a project in the Elpro India company campus in Pune. There was a need to refurbish the structure and build a school for the children of the employees working in the same campus. But the space was small and poorly built. Under the budget assigned for the project, it was not possible to demolish the entire existing building and reconstruct it. Hence, there was an effort from our side to turn a pure RCC corporate construction into more green & kid friendly environment.

USP: Strong concept, passive cooling strategies, xeriscaping.
