ENHANCED PASSIVE DESIGN INTEGRATION OF PASSIVE AND ACTIVE DESIGN INTO LOW ENERGY SYSTEMS FOR SUSTAINABLE ARCHITECTURE

Abstract

This paper aims to examine various types of passive low energy systems as an enhanced system to integrate passive and active design. The focus is on passive low energy systems as another alternative in approaching sustainable architecture. Low energy systems are studied intensively with precedent studies to construct a taxonomy of these systems, thus providing a better understanding of how the systems work. After which, the systems are discussed further in relation with human comfort and energy consumption where its potentials and limitations are explored and how an architect can and benefit from implementing such systems. Chapter 1 introduces and explains the need in passive low-energy design and the reasons of integrating both passive and active design strategies with low energy systems. Chapter 2 identifies the definition of passive low-energy systems and the selection process. Chapter 3 sets up a taxonomy of low energy systems and presents case studies to further understand the implementation of low energy systems. Low energy systems: Evaporative cooling, geothermal systems, Earth cooling tubes, Cooling slabs, Automated sun shading device, low energy day lighting systems, night ventilation and double façade. Chapter 4 creates an understanding of low energy system in relation to human comfort and needs. In addition, low energy systems are discussed showing the relationship between passive low energy systems with human comfort and the climate in general. The method of representation of the systems will include the psychrometric in ECO TECT program Chapter 6 discusses about the architect’s role in implementing such systems in design, its limitation and possible future directions
