Abstract

Global warming is an issue that trend today. Awareness needed to perform its main energy efficiency is the energy cooling operations. Its because energy is related to the operational life of the thermal comfort of occupants to perform daily activities. This paper identifies residential design typology of house type 60 as a building envelope design and configuration space. The research determines the thermal performance and explore a simple house type 60 for its energy efficiency. In general, this paper aims to identify the typology of house type 60 that is associated with the operational cooling energy savings, as well as opportunities for what can be done to conserve energy by using architecture bioclimatic approach. The main benefits expected is to provide guidance on design concepts (via the model) based energy efficient cooling for modest residential type 60 in the humid tropics in order to conserve energy and create a healthy neighborhood. It need the dweller to adopt what they want to be in their own house. The fourth dimension in housing is a strenght that enable people to materialise their house to what they envisioned and using it to achieved what they intended to be.

Abstract

The increase of waterfront buildings’ height has an effect on wind distribution in the urban canyon. On the other hand, the distribution of wind is needed in providing thermal balance in urban environments, especially in urban waterfront coastal areas. This study aimed at observing and analyzing the effect of building height (H) on waterfront buildings and aspects of the length to width (L/W) ratio related to the length of the canyon design. The observation was focused on the wind speed distribution. The research was an experimental research using ENVI-met V3.1 software for simulation. The results indicated that short canyon (low L/W value) results in lower wind speed changes compared to that of long one (higher L/W value) at all altitude levels. The short canyons provided more stability in wind speed reduction. The 15 meters wide of canyon design contributed to the highest average wind speed. Overall, the existence of a barrier building would result in a negative area of air flow and create a calm area within the distance of  ± 50 meters.
