Daylight performance of courtyard wall design at low-cost flat in the tropics

Courtyard in a low-cost flat in the tropics provides daylight but it is usually protected with a corridor to control the solar radiation. Surrounded by a shaded corridor, daylight level of the adjacent dwelling rooms around the courtyard are reduced. Modification of courtyard wall by integrating a sloped light shelf is proposed to improve the daylight level on dwelling room and control excessive light penetration at the corridor. Experiment with simulation as a tool was used as a research method. Illuminance value, Daylight Factor and uniformity ratio of the base case, a courtyard wall design in a typical low-cost flat in Surabaya (latitude 7�15�55��S) using louver and case, a proposed courtyard wall design using sloped light shelf were compared, simultaneously with daylighting standards. The results demonstrated that courtyard wall modification reduced excessive average illuminance on the corridor in the range of 41% to 57.1% and improved average illuminance in dwelling room in the range of 0.9% to 19.2%. The proposed courtyard wall also increased illuminance uniformity ratio in both corridor and dwelling room. In order to improve daylight quantity and quality, a courtyard wall with sloped light shelf can be applied on a low-cost flat in the tropics

PUMICE LAYER: A SOLUTION TO DIMINISH THERMAL ON HORIZONTAL LEFTOVER PLACE IN ROOFTOP

There are many ways to solve thermal on buildings, such as the installation of horizontal and vertical sun-shading devices on four-direction facades. However, rooftops are often ignored. In low-rise to high-rise buildings’ rooftop, there are leftover places exposed to solar heat radiation all day. Some rooftop places are equipped with polymer thermal roof insulation, and some are even without outer thermal insulation. The research aims to find a solution to diminish the horizontal thermal radiation by using eco-friendly material, pumice, as an outer thermal insulation. Exploiting method was used on one roof model as a conventional rooftop (without outer insulation), and another as a modified rooftop model covered with pumice. Couple HOBO data logger U12-012 temperature sensors were used to measure rooftop surface temperatures and room model temperatures. Results show that the thermal radiation were blocked efficiently: 26oC on pumice covered rooftop. It saved 8.4oC room temperature

Remarkable 3-in-1 Pakis-Stem Green Roofs for Saving Thermal Flat Rooftop

The green councils in the world are often promoting green buildings in terms of energy savings by mitigating the thermal load on buildings,especially thermal rooftop, into the room. Green roofs can be the most effective to lower roof thermal in tropical regions, but complicated and costly to build a perfect green roof even for a simple extensive green rooftop. This research looks for a remarkable growing medium for constructing green roof. Pakis-stem blocks can perform a 3-in-1 function: as a light-weight growing medium for green rooftops, an easy-to-form urban farming in private buildings or residences, and an eco-friendly external roof insulation. After a deep measurement on the rooftop surface and room thermal behaviour, the pakis-stem green rooftop can reduce 16.4oC of surface dry-bulk temperature and approximately 7oC ambient room dry-bulk temperature lower compared to conventional rooftops at noon. Furthermore, the surface temperature and ambient room air temperature difference between Pakis vegetative green rooftops and miana scrub green rooftop is approximately 7oC and 3oC respectively

Perception Study on Kinetic Recycled Compact Disc Facade in Tourism Hall, Jarak - Wonosalam

Indonesia is a country, rich with culture and natural resources that brings high tourism potential. Jarak village in Wonosalam is one of the villages in East Java that has these tourism potential, besides the religious harmony between the dwellers that initiates the construction of a tourism hall with the concept of sustainability. The hall reflects the harmony between man and nature. The tourism hall uses the kinetic panels from recycled compact discs as the facade, which is rotatable when blown by the wind. This research is meant to study peoples perception of the installed kinetic facade panel. Here, we divide the respondents into two groups, professionals (academician and architects), and non professionals (Jarak dwellers, visitors and general). The aspects observed are psychology, aesthetics, flexibility, impact to the environment and economics. The result is that there is a difference in perception regarding the flexibility, and also, the colour aspect of the installed kinetic facade is the most memorable aspect of the installed kinetic facade

The Value of Corridor in Flat as Place Attachment In the Life of the Dwellers

Abstract. Place attachment has been researched extensively in the behavioral and architecture studies over the past two decades. In the production of housing, designers mainly focus on the quality of the physical components. Place attachment is just the form of connection between a person and the environmental setting. However, it is challenging for this study to grasp the aspects of meanings and attachment, both in the level of personal, community and natural environment contexts, which are not adequately considered in the design process. In this study, three dimensional model of personal and community attachments to their corridor in flat, was conceptually and empirically examined. The aim is to testing an integrated approach to measurement of place attachment at corridor in flat in understanding the values of places in the life of the dwellers. Sample cases include examining attachment to corridor in three flats of Surabaya, Indonesia. It was evident that the value of corridor as a places was affected with their daily experience of the places, social bonding, neighborhood interaction and landscape values

Historical Old �Kampung� Toward Sustainable Green and Clean Habitat

The rapid develoment of modern city was not totally achieved by hundreds of old dwellings within it. Old settlements and residences, which are settled side-by-side, consisting of small-sized houses called �Kampung�, keep making a better living environment and socio-economical condition, even accomplishing creative remarkable programs toward green and clean sustainable habitats. These programs come from the Aga Khan Award for Architecture called �Kampung Improvement Programme [KIP] on 1968-1993, C-KIP (1995-2003) and Surabaya�s Government Green and Clean competition creativity agenda from 2005 to now. This paper explores the objective and the spectacular programs on old kampungs. Each kampung participated in achieving the highest award by introducing many programs such as planting greenaries and fruits, recycling dry and wet wastes, producing greenary gas and eco-friendly fertilizer, filtering and reusing grey water, and planting medical plants as well as conducting waste bank in order to increase the sosio-economic activity in the kampung by stimulating people to collect and separate daily waste
