Abstract
The concept of redevelopment is accompanied by actions and forecasts to improve the quality of the physical-spatial environment inthe cities, that is by the emergence of new facilities and conditions, improving the spatial environment is achieved. This requirement occurs when the coherence, coordination and the performance of the urban area is diminishing and is not responsive to the requirements of that area. The brownfields are amongst the inefficient urban areas and require redevelopment, which mostly include Deteriorated buildings accompanied by environmental contamination. The main issue of the present study is the lack of a compiled and appropriate roadmap to redeveloping the brownfields in Iran. Accordingly this article is seeking to introduce and present the defining indicators of brownfields, adapt these indicators to Iran's condition and achieve the redevelopment roadmap of these lands in Iran. In this regard, the codification of this article has been done by the descriptive-analytical method. Results of the study show that the main problem of Iran's planning system is the lack of a regulatory and legal description of brownfields on one hand, and absence of a compiled roadmap to lead urban development into the zone and use the capable potentials and opportunities for redevelopment

Abstract
Today constructing high-rise buildings which consist of a great amount of surface area and also openings is prevalent and is continuing to rise. Therefore, the building’s envelope is among the most important elements that has a great effect on energy consumption and wastage. As a result, Responsive Architecture focuses on the design of the external skin of buildings which can change their physical properties in order to respond to various environmental conditions. These facades can play a significant role in reducing energy consumption produced by fossil fuels and maximizing the use of natural energies. This study aims to simply review and categorize the various solutions provided by responsive architecture in order to reduce energy consumption in contemporary high-rise building skins. To achieve this goal there has to be a clear image presented of the impact of these responsive systems on energy consumption and how they actually function. In this regard, comparative studies on some of the most basic studies concentrated on the subject, and also a few case studies well-known in this area of matter were precisely reviewed with a descriptive-analytical approach. Accordingly, a general assortment of responsive architecture solutions and performance in high-rises were attained and gathered which can be classified into two groups; those applicable for vertical facades including “Kinetic Facades”, “Double-Skin Facades”, “Smart Materials and Windows”, and those for horizontal facades including “Kinetic Roof” and a new type of “Ventilation Stacks and Exhaust Ducts”. These solutions can be operated in combination with each other or for the better performance of another system, depending on environmental conditions. moreover, they can be applied for either new buildings during their construction or even the old ones by installing them separately from the main facade. They can control the energy consumption of the building and minimize the use of mechanical systems by increasing the amount of received solar energy, reducing internal energy wastage, receiving optimum natural daylight, creating natural ventilation, controlling the amount of excess received heat, regulating temperature through energy storage and generating electricity. Responsive architecture solutions show that they can not only make it possible in getting the maximum advantage of renewable sources, but can also extend the useful life of buildings, and produce a quality of experience that reconnects people to the environment and provides delight in their lives.
