A HOUSING FOR THE COMMUNITY OF WANATHAMULLA

Project

Site Wanathamulla Sri Lanka

Duration Oct 2021 Nov 2021

Software

PROJECT SUMMARY

Housing is a collection of dwellings where people seek shelter, comfort and security, where it is also a collection of people creating bonds to form a community.

The proposed housing given in an urban setting part of urban renewal project It about program a land redevelopment of given context The proposing design is expect to clear out blighted areas of the context and create new opportunities for better housing and economy by creating various activities to improve the quality of life in urban context.

RANMASU

A CONTEMPORARY LEISURE GARDEN @ ANURADHAPURA

PROJECT SUMMARY

Ranmasu Uyana is a well known historical site in the secret city of Anuradhapura, which located along with the built element comprising the complex of Isurumuniya and Thisa wewa tank It is believed to have been first laid out in 3rd century BCE Ranmasu Uyana is well planed and large park complete with its own irrigation elements, pavilions, bathing pools and some other unique architectural features, and stand as a fine example of landscape driven architecture of ancient Sri Lanka.

SPECIALIST STUDY

A STUDY ON PASSIVE THERMAL COMFORT: CLIMATERESPONSIVE VERNACULAR ARCHITECTURE IN TROPICS

Project type Dessertation

Site Location Central province Sri Lanka

Duration Jan 2022 Apl 2022

Abstract

This study depends on investigating and surveying passive solar design procedures that advance high warm solace in vernacular houses in a tropical setting. The contextual investigations give valuable knowledge to planning energy effective spaces that offer a thermally agreeable environment. An examination depends on focal Sri Lanka in the Kandyan(Central Sri Lanka) setting to address tropical vernacular architecture.

The author has chosen vernacular structures constructed with different construction materials such as stones, earth-compressed bricks, sunburnt bricks, clay, and timber. The developments are done as a reaction to the area's microclimate to give the most significant degree of indoor thermal comfort. The data collection is done through instruments that measure temperature, humidity, wind speed, and solar intensity to analyze the thermal comfort standards. Furthermore, a survey was conducted among the inhabitants of each house in March 2022.

Results showed that every one of the houses displayed a lower surrounding temperature than outside during the day. Clay and lime mortar were critical materials for developing higher thermal capacity walls. Sufficient ventilation is enormous in creating a comfortable environment A higher aperture to volume ratio is essential to cool the thermal mass of these houses. Solar radiation is the primary thermal gain for a structure. The importance of thermal buffer zones can be seen. This is an all inclusive way to deal with understanding and characterizing solace conditions fizzles. The inhabitants of these houses were agreeable in conditions described as awkward by ASHRAE and Nicol's comfortability standards

Vernacular Architecture

• Architectural styles that are purposely introduced for aesthetic motives beyond utilitarian needs distinguish vernacular architecture from polite architecture

• Vernacular architecture is broadly defined, The non professional architectural practice encompasses a wide range of activities, from the construction of simple huts for nomadic tribes

• Many diverse behaviors and theoretical stances are referred to by this term, and it is often used as a shorthand or a synonym for them A few examples of these are "primitive or indigenous," "indigenous," "traditional," "ethnic," "ethnic ," "non pedigree" and so on: primitive or aboriginal architecture, indigenous architecture, ancestral architecture, folk architecture, popular architecture, and rural architecture (Fathy, 1986).

• Local demands, construction materials, and customs are all taken into consideration when designing vernacular architecture.

• It is believed that that vernacular architecture makes up at least 90% of all buildings in the world, it's safe to say that the vast majority of us were reared in one.

Thermal Comfort Standards

• Standard 55 2017 Thermal Environmental Conditions for Human Occupancy (ANSI/ASHRAE Approved)

Thermal Environmental Conditions for Human Occupancy, notes that for thermal comfort purposes, temperature range from between approximately 67 °F(19.4°C) and 82 °F(27.8°C). A more specific range can be determined from the standard but depends on relative humidity, season, clothing worn, activity levels, and other factors The recommended relative humidity for comfortability is between approximately 30% and 60%.

• Nicol thermal comfortability predictions

Humphrey in 1981 determined a numerical connection between the comfortable temperature (Tc) and open-air temperature (To) for an inactive structure: Tc = 12.1 + 0.53 To (Nicol, 2001). He gathered information from solace studies from the whole way across the world and plotted the temperature revealed as agreeable against outside temperatures for the long stretch of the review. Afterward, Nicol and others (2001) finished up after comparable exploration in the Indian sub-landmass: Tc = 17.0 + 0.38 To.

Conclusion

"There is a clear need to further develop the traditional systems based on natural resources. Before inventing or proposing a new mechanical solution, traditional solutions in vernacular architecture should be evaluated, and then adopted or modified and developed to make them compatible with modern requirements". (Fathy. H., 1986)

• As in the above quotation referred from Fathy, development based on traditional systems should be prioritized before mechanical solutions, which vernacular and modern society tackle the same problems differently.

• Where vernacular people are solved by climatic responding and contemporary designers solve by machinery creating overconsumption, damaging the natural climatic ecosystem

• Moreover, the research reflects how mechanical energy can be replaced in extremely straightforward and tiny structures for an contemporary structure to accomplish a safe place for its tenants.

• Hence, to decrease energy utilization and contamination, utilizing clean energy sources like a breeze, water, and Sun, which have no contamination and minimal expense creation, could be a brilliant other option.

• Previously, petroleum products were not as accessible as they could in current times, and engineers were utilizing basic yet intelligent techniques to involve existing average energy in their planned structures.

• The Study that has been attempted on these vernacular structure types exhibits that vernacular structures offer a diminished utilization of energy with a massive hole contrasted and current structures.

Recommendations

1. The use of high thermal mass materials for residential construction such as earth-compressed bricks, sunburnt bricks, stones/granites, and clay over lower thermal mass materials such as timber and cement blocks for flooring and walls in favor of a passive cooling strategy.

2. Thicker external walls with high thermal materials for even better indoor and outdoor thermal filtration in an outdoor high thermal tropical environment.

3. The design of a higher aperture area to volume ratio within the structures helps effectively cool the indoor environment.

4. An efficient air movement within the structure for better regulation of temperature and humidity within the building as humidity is higher inside a building compared to outdoors.

5. Design thermal and solar radiation buffer zones facing building orientation with the highest solar gain. A buffer zone significantly reduces the indoor thermal gain, and solar radiation is the primary thermal gain within a structure in tropical climatic conditions
