1 Responsive Architecture

2 Buildings need modification
Buildings need to change and modify in their long lifespan since the demands of their users and their environmental and social context change in their lifecycle. Although change is a constant part of a building, it is not easy to design and build for change It is hard to anticipate the change, so it is hard to design for it It is more costly to build with the ability of alternation than traditional way of building The concept of responsive architecture comes form the fact that buildings need change in their lifespan.

3 Approaches to building need for change
Open building concept: Architect only design the fix core of the building that is constant and the rest of the building ((infill part)) is changeable by the occupants Building composed of different structures that each have a different change cycle Site, structure, skin, services, space plan and stuff Consist buildings are a recent phenomenon and there is a variety of light- weight and dynamic structures in architecture history Mobile homes and houseboats Interactive architecture Newest approach in this area which came available by new developments in computing and emergence of new materials

4 Buildings behavior Traditional buildings Interactive buildings
Optimal bandwidth of performance for limited conditions Condition change make them perform poorly Running cost is low Change cost is High Interactive buildings They curve the bandwidth of performance, change of the condition does not affect their performance Running cost high Change cost zero Different between traditional building and interactive building Change cost in interactive building count as run cost, so the change cost is zero

5 What is interactive building?
Building as a whole cannot be interactive It consist of many parts, some of them are interactive and some of them are constant Combination of this parts make a building interactive A system that take user into account and is more complex than turning on or off is an interactive system An interactive system consist of sensor – controller – actuator - material Sensor register the environment Controller decide what kind of action need to be taken Actuator make the desire change happen Material realize the physical parts of the system

6 Interactive System Interactive System Consist of:
Sensor which register the environment Controller that decide what kind of action need to be taken Actuator, make the desire change happen Material which realize the physical parts of the system

7 Classification Environmental interaction: User based interaction:
Architectural uses consume 48% of total energy in U.S. Façade of the building is responsible for 40% of heat loss. User based interaction: Redefining architectural elements to such as window, wall, door, etc. A shift form static and single goal elements to dynamic multi functional elements to make the whole building smoother and intelligent. I am investigating interactive architecture based on these two classification. Adaptive Facades are one of the answers to these problems

8 Environmental interaction
4 dominant physical parameters that responsive facades interact with : Thermal - Optical - Air-flow - Electrical 4 dominant physical parameters that responsive facades interact with: Thermal: adaptation causes changes in the temperature balance of the building. Optical: adaptation influences influences occupants visual perception. Air-flow: adaptation to provide natural air circulation. Electrical: adaptation generates electrical energy. (photovoltaic panels).

9 Environmental interaction
Most examples of responsive facades influence more than one of 4 domains. 4 domains along with all possible multi physical overlaps together, create fifteen different combination which is shown here.

10 User based interaction
The key characteristic is that it take user into account. Occupants and building elements exchange information. It is believed that in less than a decade more than one billion people will spend half as many hours in front of the computer screen as they will in physical space. One of the main ideas is communicate information through architecture. The example is ambient room. In the end, I want to examine social improvements and behavior influences of responsive architecture. Is it possible to improve sense of belongness of a space along with environmental suitability ?
