Malaysia is one of the countries having a large number of tall structures. This is one of the engineer’s initiatives to maximize land use due to the growing population. This rapid development endangered the environment through energy consumption and carbon emission in Malaysia. This study aims to design high-rise structure buildings using Esteem Software that differ in shape and to offer the most efficient models of high-rise buildings based on embodied energy (EE) and cost performance analysis. These analyses were divided into two categories: EE of a building which was calculated by considering the Hybrid life cycle assessment (LCA) method and the entire cost of the materials utilized in building construction. Furthermore, the study is limited to the cradle to gate phase only. The results demonstrate that as the number of sides increases, so does the value of EE and cost performance. It can be seen that the shape's performance while keeping the same value is significantly related to the number of sides of the shape.

Hydrological modelling is a conceptual representation of a complex characteristic of real hydrologic features which developed to understand, analyse, predict and manage water resources in a watershed. The simulation of surface runoff was developed in the catchment of centre in Perlis State by using Hydrologic Modelling System (HEC-HMS). Estimation and prediction the flow in ungauged catchment were carried out by transporting parameters from the gauged catchment. In this study, parameters for ungauged catchment were derived from information close to ungauged catchment. The percent difference of peak flow and runoff for calibration at donor catchment showed reduced from 8.9% to 5.9% (peak discharge) and from 29.19% to 6% (volume runoff). The model calibration was indicated the value of Curve Number is 60 and the recession constant is 0.8, respectively. The result showed that the model successfully predicted of gauged catchment runoff and peak flow for calibration (94% and 94.1%), and validation (85.12% and 79.95%). This study have a significant contribution for future development of water resource in Perlis State and in ungauged catchment of Perlis.
