Tropical house

The idea is to create healthy habitation space at one of crowded area at Klender, Jakarta.

Creates naturally lightfull rooms, and well cross ventilated was the first target.

Then considering to prevent flood, that many of people suffer at rainy season, i propose to reduce the land covering. it means we tried to build open grounded area in side the house. and also water collection chambers which allows rain water absorbtion to the ground. To make water cycle.This is a chamber with clay wall, non cemented. which allows water absorption back to soil. located at inner courtyard/garden. collecting water from rain, and grey water from shower, bathing water, and overflow from septic tank. Which may keep the ground water keep stabilized.

My client cares about the micro climate in side The house.
The glass doors big and wide openings, Transparency let the light penetrate deep inside the rooms.
and for more, i add 'bovenlicht' an upper windows lets the bouncing of light thru from the perimeter room.

the program was:
*grounded master bed room, (i add : which has direct access to inner courtyard)
*spacious living room(i add : which can be combined with reception room, to add more space)
*neat kitchen and dining table.
*the bathroom is no need too close to the bedroom. preferred not detached or same wall, worrying humudity
*for more, ai add that, the social space such as living room, family room has opening to inner garden/courtyard. to get better fresh air circulation and natural light.
*2 bed room on upper level, with sitting room.
*the service washing and drying area is located at top rear area.
*water tank located under roof.

this is the ground floor layout:

can't wait to be built...

Bio Climatic Approach in High rise Building

Natural Ventilation systems rely on natural driving forces, such as wind and temperature difference between a building and its environment, to drive the flow of fresh air through a building. Both work on the principle of air moving from a high pressure to a low pressure zone. Natural ventilation systems are usually integrated into building systems where there is some mechanical support; these are called mixed mode or hybrid ventilation buildings. The main benefit of some augmentation by mechanical systems is that there is less unpredictability with indoor environment conditions, though it will result in greater energy use.

Natural ventilation can be an appropriate choice when compared to air conditioning in the temperate climate of Victoria, particularly as the nights are cool and this can be used to pre-cool the building (see CH2 for case study of natural ventilation used for night purge www.ch2.com.au). It can save substantial amounts of energy by decreasing or eliminating the need for mechanical cooling. It may also improve the building’s indoor air quality. Buildings with well-designed natural ventilation systems often provide very comfortable and pleasant environments for the occupants.

There are two fundamental approaches to designing for natural ventilation that will be effective in most Victorian situations:

> Cross ventilation which uses air-pressure differentials caused by wind

> Stack ventilation which uses the increased buoyancy of air as it warms up

Depending on the approach when using natural ventilation, a conscious choice may need to be made by the building users to have greater fluctuations in indoor thermal conditions. The temperature will not always be predictable to plus or minus half a degree, as the use of external air will, if it is not tempered using mechanical systems, mean that temperature and humidity vary.

Design issues to consider with cross ventilation

Using cross ventilation will have a strong influence on building aesthetics and site planning. To maximize the effectiveness of openings, narrow buildings with open plans and well placed openings work best (particularly if the longest faces of the building are perpendicular to the typical wind direction). Furthermore, single-loaded corridors (rooms only on one side of a corridor) will provide better airflow than double-loaded ones as it makes it easier to provide openings on opposite walls. Building elements like fins, wing walls, parapets and balconies may be designed to enhance wind speeds and should be an integral part of cross-ventilation design though caution needs to be taken that they do not cause turbulence and block air flow)4

In one of my high rise project, we are determine to apply bioclimatic approach.

At the attic -crown, we attempt to provide natural cross ventilation, for the hot air which reheated under the glass room.

these ventilation will drawn the hot air out, to be replaced by fresh air.

Although the outside natural air is not cool at midday, but its flowing and changes effects the temperature of the glass or the building skin.

Concept Jatibening

a friend , Bonis, ask me to design his house at jatibening Bekasi.
he gave me a site with west facing side most. 26m length and 8.5m width. Jatibening is a dusty area, so i sugget to put screen vegetation at front.

the innercourt house concept, which can enhance the cross ventlation, provide natural lighting and innercourt vistas.

this open space which also generate distance for master bedroom privacy to communal space such as living & gathering room. whilst the guess room is outside the main house, connected to Pendopo as receiving area.
this pendopo, was ment to be 'lawasan' javanese pendopo from [old] joglo.
the eclectic nuances explore in this area, which re-romancing the childhood of the owner.

the position was rotated to match the site, and facing the road/entrance.
this pendopo will be the focal point of this house from beginning.

Living-dining room, was the heart of this house, the spaciousness created from it's open & transparent wall. the main vista is the inner courtyard.
The upper level of this house, at the same sleeping area, two kids
bedroom and one toilet are prepared for their kids.
the service area located over the living & pantry, the maid's room, one toilet and washing area, also drying area under roof. which has louvre wall at west side.

these would be all for now, still waiting for their respond for this design.

Apa Kabar Rumah Ocha?

Apa kabar rumah Ocha?

Client : mamanya Rosa Yulita

Status : Built 2007

Progress :

akhir 2006 pernah survey ke rumah ocha, masih bangunan lama.

awal 2007 baru brainstorming sama temen2 bla; van, hendro, adit.

tiba-tiba saja lapangan sudah mulai tanpa konfirmasi, gambar malah menyusul.

untung saja sempat melakukan revisi di lapangan. sehingga kamar mamanya tidak kekecilan.

masukin gambar facadenya susah banget, karena gagal terus di attach.
