Über dieses Buch

This is the first book to describe the development of and state of the art in solar shading devices in buildings, detailing all methods of evaluating shading systems according to thermal and visual comfort.

The issue of energy balance in buildings is gaining importance as conventional energy sources dwindle and become more expensive. As such, environmental concerns should be considered in overall design decisions.

The book discusses the role sun control “machines” play in controlling solar and thermal radiation. It examines their geometry, their position in relation to glazing and their operation (in the cases of movable systems) to control the heat and light entering a building, as well as how their material and color influence their performance.

This book appeals to architects and designers who are interested in efficient energy facade design.

Chapter 1. Introduction

Abstract
The issue of energy balance in buildings is of significant importance nowadays, since conventional energy sources are running out and becoming extremely expensive. In addition to the development of an environmentally friendly design is being a basic requirement for new EU directives, the above mentioned facts are the main reasons behind making the passive design of buildings one of the most crucial and fundamental factors in buildings’ energy savings. Basic environmental design parameters should be carefully implemented in the overall design decisions.

Chapter 2. Design of Shading Systems: The Basics

Abstract
Shading systems play a major role in buildings’ aesthetics and energy performance. For this reason, they are the focus of interest for various architects from their role as designers and researchers.

Chapter 3. Shading Systems: Their Relation to Thermal Conditions

Abstract
Although we cannot actually divide sunlight into heat and light, in this chapter we are going to focus on the basic quality of shading systems which is to reduce heat gains and ensure thermal comfort in the interior. We will analyze the quality of solar radiation and how sunlight behaves in relation to the building. We will analyze the methods, the parameters and the proposed shading systems according to them.

Chapter 4. Shading Systems: Relation to Daylighting

Abstract
Basics of shading design in relation to both daylight quality and energy savings, through decreasing the amount of electric light needed. More specific requirements for the case of office buildings is presented.

Chapter 5. Generating Energy Through the Use of SDs

Abstract
Additional parameters of energy production that shading systems with integrated PV can support are presented.

Chapter 6. Remarks on Shading Systems

Abstract
Over the last century, the proportion of the office buildings’ envelope that is transparent has increased significantly. Due to the low thermal insulation property of glass, in comparison to mass opaque building materials, the larger the transparent fraction of the building’s envelope, the more important is the control of solar energy inflow, in order to keep thermal and visual conditions indoors in acceptable levels. Transparent facades need an additional control system, one that helps avoid solar radiation during the overheated period, allows enough thermal loads during the underheated period and ensures comfortable visual conditions during operating hours. Due to the fact that passive design is most of the times not totally efficient for the control of solar and thermal gains, additional active systems are used to balance the interior thermal and visual comfort conditions. As a result, today’s buildings are dominated by technical systems for heating, cooling, ventilation and artificial lighting often resulting in high conventional energy consumption.
