Nyaya Health

PROJECT DESCRIPTION:

This proposal aims to act not only like a mere physical entity, but a total investment program that has a potential to help the people of the region to cope with their problems, from the money flow processes up to post-construction consequences. That is why also project management concepts were shown in the presentation board. The proposal endeavors to select the best option to help the people of the region be a part of the construction process both to fulfill the public participation, and the financially horizontal distribution in order to bring a humble but important economic vitality to the region. In order to achieve these goals, the building materials have to be gathered from the closest radius. And materials were decided according to the local capabilities of Sanfe Bagar. Vernacular building techniques are intended to be promoted. However that does not mean that non-professional workers are not welcome, vice versa, the construction process aims to make people, particularly the women to take advantage of their construction experiences after the construction to add an income to their poor households. By having a large and local labor, possible alienation feeling is aimed to be avoided, as the builders will be the users themselves. The proposal even humbly have advices to Nyaya Health, since it is known that the health problems are caused by economical problems (lead to emigration) so Nyaya Health can upgrade the economical sustainability of the local people by letting them to gain new skills in the construction process and after…This participation can upgrade the social sustainability, which will hopefully result in a better relationship between the Nyaya complex and the local people. To conclude the social-economical aspect, the proposal mainly aspires to boost up the self-confidence, self-appreciation of the local people by a rational self-production. In addition the wages are thought to be relatively low in the region that makes the whole management concept economically profitable. This conception has its reflections in architectural composition, like the upwards movement which tries to promote dynamism and framing the familiar scenery which intends to let the local people appreciate the beauty of their own country. Also the courtyard plan, accentuates the user-centeredness. 

Physical features of the proposal are in fact totally in collaboration with the socio-economic and psychological sustainability since a physically sustainable architectural entity may positively affect the feeling of independency of its users. Physical sustainability has been given extreme importance and it is the main form giver. The roofs are inclined to meet perpendicularly with the summer sun which will heat up the roof and the large opening directed towards the north elevations will let the warm and exhaust air heated by the roof outside, this movement will cause a drift of cooler air from the lower levels ending in an air circulation in hot days. So actually solar power is used passively for air circulation which will provide cooling by evaporation on human skin. Also the wooden panels that are filled with straw insulation promise an extra space when the northern roofs are opened in hot days. In countries with hot climates, people sleep on their flat roofs, but here in summer days heavy monsoon rain prevents both flat roofs and the sleeps that could be done on them. So these mobile wooden panels promise a place to relax (particularly for staff quarters) with a strong air circulation without being effected by rain. Also driving rain is not a problem as the local dominant wind is known to blow from the south from which the panel-platforms are protected by inclined roofs towards north. Also wind is not directly let in to protect the desired air circulation based on air density, but the wind assists this circulation as the wind from south to north creates negative air pressure zones in the north facades which will end in even better air drift. Towers and stage al together forms a dynamic portal to the complex. The stage takes advantage of the courtyard as a gathering space and turns into a mini public square. The shorter tower houses a small storage for the stage and is the main place for internet connection equipment whatever technology is selected. The tall tower stores the monsoon rain water. With its roof panel shut, it also creates an air circulation and helps the water cool down. So in summer days the complex can have its cool water with potential power of the tower, so no extra plumbing engines are required. Counseling rooms are put near the portal for easy access, on the contrary the staff quarters are placed on the north of the courtyard for a better privacy but not isolation. The southern walls of the staff quarters are suitable for exhibitions for public and training reasons. These southern walls have mobile eaves to imprison the absorbed solar energy during winter days in order to take advantage of it at winter nights, as thermal mass. The building materials are:

1. Natural Stone for foundations

2. Adobe bricks for both structural and non-structural walls 

3. Wood for beams spanning 3 meters (larger sections for beams of the eaves and two exceptional wooden trusses of the meeting hall)

4. Twig+straw+reed matting panels for mobile units with insulation

5. Reed matting for groundcover. 

6. Slate for roof cover.

In case these materials cannot be produced, all of them can be altered with industrial materials like r.c. or concrete or baked bricks for adobe walls, metal roofing for slate, however in such an alteration all the social approach concepts will be harmed.

SHADED VILLAGE

 

PROJECT DESCRIPTION:

SHADED VILLAGE

How to create a production and technology complex in the middle of a rainforest? How to create a factory in a sustainable way? How to minimize the impact of a 1300 sqm unit while respecting and protecting a unique environment and biodiversity?

The Shaded Village project aims to integrate the traditions and culture of the indigenous community with the Fair-trade market needs in an environmentally responsible, profitable and healthy complex deep into the Ecuadorian Amazon.

In doing so, the Shaded Village project combines the advantages of a single building strategy (overall shading system/energy producer) with a more village-like strategy (local typologies, flexibility, ease of construction).

In terms of sustainability, the design of the Shaded Village intends to increase natural ventilation and use of alternative energies such as PV systems, biomass combustion (from cocoa waste), micro-hydro system, and waste/pure vegetable oil generator.

SITE PLAN

The complex is planned at the southern edge of the site to integrate a maximum of existing vegetation into it, while reducing the road access impact on the most level area.

The orientation of the buildings is totally dictated by the cardinal points to lower the interior solar gains and favor a natural N-S cross ventilation of the units. The N-S spacing in-between units is also regulated by Mahoney’s theory to maximize natural ventilation.

The implantation and typology of the buildings (perpendicular to the slope, and “lifted” from the ground) let the water run down the mountain to the river to the east.

BUILDING PLAN

Planned like a one-road village at the southern edge of the site, the complex is organized along a main path thought of as a main communication link. That link is part of a walk on the rest of the site, where organic gardens are developed. Plugged onto the path, all closed functions are allocated within several covered units built in traditional materials. The spacing in-between is wide enough to house public external spaces, such as picnic area, handcraft market, botanic gardens.

The design minimizes site disturbance by preserving existing relief and natural vegetation. The landscape design supports biodiversity and preserves natural habitats.

BUILDING ELEVATIONS

Unlike a one-building operation, such a fragmented ‘village-like’ organization does not only provide a regional look to the complex and a maximized contact with the environment while increasing natural ventilation, but also offers a useful flexibility in terms of adaptability to ground differences, easiness in building process and potential future extension.

To increase natural ventilation’s efficiency, the whole complex is covered by an overall efficient shading system made of bamboo and solar panels producing energy. This feature will help to maintain an enjoyable condition for workers and visitors, as well as those who view the complex from the overlooking surroundings.

SUSTAINABILITY – VENTILATION

The over-present concern about increase of natural ventilation is evidently encouraged to cool the different spaces and to avoid as much as possible the use of air conditioning systems. This operation has a double advantage: to lower operating costs and to obtain a more efficient sustainability. To achieve this, a specific design (roof/shading system) observable mainly in section has been implemented into the Kallari Association project.

SUSTAINABILITY – ENERGY

Definitely aiming for an autonomous energy strategy, the Shaded Village project has to adopt an hybrid solar system (PV system (photovoltaic) to produce electricity and Solar water heater systems to heat water), combined with one or several of those other possible techniques (to be developed in a future phase):

– Biomass fermentation/combustion (from the cocoa waste; via gasifier system)

– Micro-hydro power turbines or generator (from the river) 

– Waste / Pure Vegetable Oil generator (from industry / agricultural gardens)

Although probably being the most exciting technique for the Kallari Association project, the biomass combustion from cocoa waste is not yet operable. Nevertheless, learning from former experiences of controlled biomass combustion in remote communities in the Amazon basin, a specific project for a chocolate production community could be developed potentially in collaboration with the CDEAM – Federal University of Amazon (Brazil) (cf Dr. Ruben Souza). They have recently been in charge of some sustainable developments of Amazon remote communities living from the production of cupuacu and açai pulps (fruits from the Amazon). In that scope of work, they developed autonomous energy systems using the cupuacu and açai waste to produce electricity.

In addition to those energy supplier systems, a sustainable vision should be integrated within the operating management of the complex, by using, for instance, solar or high efficiency cookers, fluorescent lights (rather than incandescent), etc.

SUSTAINABILITY – WATER

A sustainable water system is achieved by: 

– collecting the rain water via the roofs design, in a central gutter, and then stored in a cistern (or pond at ground level)

– biological treatment (beds of plants and aquaria) that eliminate nutrients and bacteria and convert greywater and/or sewage into clear water (biological system as opposed to septic tank with biofilter combined to a tiled leach field)

– re-use of greywater to flush toilets

– storm water drainage system managed through buildings implantation/typology and landscaping as opposed to piping. The implantation and typology of the buildings (perpendicular to the slope, and “lifted” from the ground) let the water run down the mountain to the river to the east.

SATELLITE HUBS

The other concerns that were prevailing for the main complex are also implemented in the design of the satellite hubs: maximized natural ventilation, shading, energy autonomy (PV system), flexibility and ease of construction (or transportation) with local materials and labor.

The dimensions and the autonomous design of those standalone devices allows them to be transported and placed in every remote area.

MATERIALS

Main materials used in the Shaded Village project:
No VOC building products are used. The complex is built out of recycled (glass, tiles, painting) or sustainable – local building materials (bamboo, thatch and wood) using local labor to realize the design.
