Personal control is one of the influential factors for user satisfaction and environmental comfort due to its physical and psychological impacts. This paper aims to identify the relationship between the degree of personal control over indoor environmental conditions and user satisfaction with thermal and visual comfort. Trying to answer the...

The glazed envelopes on buildings play a major role in operational energy consumption as they define the boundary conditions between climate and thermal comfort. Such a façade is viewed as an uncontrolled load that sets the operational performance requirements for artificial lighting and air-cooling mechanical systems. This is in contrast to...

Increasing cooling demands in the built environment call for innovative technical solutions and systems for application in buildings. Cooling loads represent an important share of the total energy consumption in warm climates, especially in commercial and office buildings. Moreover, mechanical systems will still be needed in most cases to cope...

The high and increasing requirements concerning energy consumption and the interior comfort of buildings result in a demand for more efficient façade constructions. In its role as a mediator between the exterior and interior of a building, the façade takes on a multitude of functions with effect on the building’s performance. Intelligent...

One of the geometrical restrictions associated with printed paste materials such as concrete, is that material must be self-supporting during printing. In this research paper a new methodology for 3D Printing Concrete onto a temporary freeform surface is presented. This is achieved by setting up a workflow for combining a Flexible Mould...

Cooling demands of commercial buildings present a relevant challenge for a sustainable future. They account for over half of the overall energy needs for the operation of an average office building in warm climates, and this situation is expected to become more pressing due to increasing temperatures in cities worldwide. To tackle this issue, it...

Buildings are characterised as some of the greatest consumers and pollutants of the planet. However, the genesis of environmental design, in the context of its modern meaning, as shown in this paper, is not so much based on initial requests to reduce the negative pressure on the environment, but more on the tendency to ensure the continuity of...

Small-scale systems and integrated concepts are currently being explored to promote the widespread application of solar cooling technologies in buildings. This article seeks to expand application possibilities by exploring the feasibility of solar cooling integrated façades, as decentralized self-sufficient cooling modules on different warm...

Cooling demands in buildings have drastically increased in recent decades and this trend is set to continue into the near future, due to increasing standards of living and global climate change, among the most relevant factors. Besides energy consumption, the use of refrigerants in common vapour compression cooling technologies is a source of...

The radical change in architectural design transcends the individuality of design towards multivarious individuation. The immersion of parametric diagrams in the representation of architectural objects leads into a process that could be grasped and manipulated with a high degree of efficiency. Computational advanced design techniques are...

Today's society needs to face challenging targets relating to environment and energy efficiency, and therefore the development of efficient façade systems is essential. Innovative concepts such as Adaptive Building Façades might play a role in the near future, as their dynamic behaviour could optimise the performance of a building. For their...

The first law of thermodynamics defines: Energy can neither be produced nor destroyed, but only converted into other types of energy [1]. From this it follows for us and our topic of circularity in the building industry that we must deal with the energy that the earth receives or has received, the solar radiation, and can feed our requirements...

Currently, several research projects investigate Additive Manufacturing (AM) technology as possible construction method for future buildings. AM methods have some advantages over other production processes, such as great freedom of form, shape complexity, scale and material use. These characteristics are relevant for façade applications, which...

The increasing migration into cities leads to an increasing number of people stressed by noise. More and more people are moving into urban settings comprised of multiple noise sources and hard reflective glass and steel facades. The omnidirectional arrangement of noise sources like airborne noise or car traffic noise and their reflection on the...

Additive manufacturing (AM) technology is currently being investigated as possible construction method for future buildings. AM methods have advantages over other production processes, such as great freedom of form, shape complexity, scale and material use. Because the freedom in geometric complexity applies also to the inner part of the...

Many offices have been renovated to improve building performance. However, the user’s perception after renovation has not been evaluated. This paper presents user satisfaction with indoor environmental quality in façade renovated offices in the Netherlands. The study explored the correlation between facade renovation strategies and indoor...
