With the aim to limit the number of ineffective designs, this dissertation has investigated the impact of architectural design strategies on improving the energy performance of and thermal comfort in high-rise office buildings in temperate, sub-tropical and tropical climates. As the starting-point of this research, a comparative study between twelve high-rise office buildings in three climate groups was conducted. For each climate group, three sustainable high-rises were...

The main aim of this research is to reduce the energy demand of tall office buildings through architectural design. To achieve high levels of energy-saving, however, it is important to acquire a good understanding of how architectural design strategies can influence the total energy use (and different energy end-uses) individually and as a group. Energy simulations, if well-validated, can help us to correctly apply design strategies to achieve considerable energy-savings.

Tall buildings are being designed and built across a wide range of cities. A poorly designed tall building can tremendously increase the building’s appetite for energy. Therefore, this paper aims to determine the design strategies that help a high-rise office building to be more energy efficient. For this purpose, a comparative study on twelve case buildings in three climate groups (temperate, sub-tropical & tropical) was performed. The exterior envelope, building form and orientation,...

Decisions made at early stages of the design are of the utmost importance for the energy-efficiency of buildings. Wrong decisions and design failures related to a building’s general layout, shape, façade transparency or orientation can increase the operational energy tremendously. These failures can be avoided in advance through simple changes in the design. Using extensive parametric energy simulations by DesignBuilder, this paper investigates the impact of geometric factors for the...

The building envelope is the interface between the interior of the building and the outdoor environment. A building’s energy consumption to a large extent depends on certain envelope design elements. As a consequence, for achieving high levels of energysaving in buildings, design measures with high impact should be firstly defined and then optimised. This paper aims at finding energy-saving solutions for the envelope design of high-rise office buildings in temperate climates. For this...

The main objective of this study is to assess the role of building envelope design strategies on reducing the energy consumption of typical high-rise office buildings in tropical climates. For this purpose, the KOMTAR building was selected as a typical case building, and the energy usage pattern prior to and after the refurbishment was compared through a computer simulation. Through the simulations, the effect of each strategy was quantified as the percentage of reduction or increase in...
