promising approach in a comfort-centric design through the proper integration with the parametric design.
Therefore, this paper is to investigate the development process of ASF grounded on parametric design tools with
a focus towards its visual comfort indices through a controllable shading system. To that end, first, a comprehensive literature review was carried out to develop an origami-based dynamic system, and three numerical
timing patterns were then applied using Grasshopper plug-in for Rhino. In addition, the environmental plug-ins
of Honeybee and Ladybug were employed to determine indoor daylight quality via different geometrical and
physical properties. Thus, 1800 design models were prepared, based on several variables including rotation
motions, indoor view angles, time hours and transmittance properties in order to investigate the daylighting
performance and glare probability in a single office space located in the hot-arid climate representative; Tehran,
Iran. Furthermore, interactive correlations between the geometrical pattern and visual performance were investigated, leading to this fact that the proposed prototype can significantly improve the flexibility of the
shading system to control visual comfort. As the conclusion, all datasets were integrated into an algorithmic
workflow while converting its advantages and limitations into an optimization process. Finally, a full potential
hexagonal adaptive system was presented to achieve the maximum visual comfort level based on the users'
preferences that can be the basis for future investment on smart building envelopes.

Some people hope to conserve natural resources, while others my see the possibility for an endless stream of revenue. No matter the reason, most people seek some level of control over their environment, especially when it comes to personal comfort. Researchers around the world dedicate themselves to meeting the needs of human beings. One of our more basic needs, beyond food and shelter, is climate – literally making the air warm or cool. Ideally, this can be achieved using a minimum of non-renewables. Enter solar and wind, the biggest and cheapest natural sources of energy. Just these two naturally occurring phenomena are capable of responding to a major part of our human needs. Yet, only 16.7% of the globally used energy comes from renewables and only 23% of that is from the sun. Think about this: up to 90 percent of our lives are spent indoors (possibly more for an avid gamer). We always hear about the quality of the air outside, when proper ventilation and the quality of the internal air we breathe are vital for a healthy and comfortable life. Lack of proper ventilation and low quality of internal air often results in respiratory ailments such as asthma, and allergies, and can even impact the morale and productivity of those who spend most of their day in an office. One disadvantage of solar is that there may not ne enough space or suitable oriented roof area available. One solution? The facade integrated solar window. This invention is a window structure configured to form a principal chamber enclosing a base windowpane. It's actually installed on the exterior wall of the building. Besides producing energy for heat, it also provides effective natural ventilation, and can enhance the overall architectural expression of the building without actually affecting the normal function of the window. When it's cold outside, after warming the air, this air may be filtered and returned to the internal space of the building. In warmer seasons, the window structure allows for natural cooling of the space. The window structure includes a main frame, which includes a first frame portion, a second frame portion (located opposite the first frame portion), and a second windowpane located between the first two portions. An axial hinge allows the main frame to tilt on an axis away from the first windowpane. The main frame can be tilted between two positions. In the first position, it's a shorter distance from the first windowpane, and in the second position, it's further, as shown in the illustration. The surface configured to absorb solar rays is located adjacent to the second frame portion. When the main frame is tilted in the position, it allows the first surface to receive sunlight directly through the windowpane. When the main frame is tilted in the position, the first surface is prevented from directly receiving sunlight through the windowpane. Opening the second windowpane will cause air to circulate. Also, the energy-absorbing surface can warm the interior space of the principal chamber. The addition of a fan can force warm air through the rest of the building space, acting as a built-in air conditioner. We've always strived to create and maintain our creature comforts using all of our resources. The simplicity and aesthetics of something as basic as a window is just one of the many new methods we continue to develop to use as much of our planet as we can, without using it up.

Building Information Modeling (BIM) has been identified as an effective tool for building performance analysis virtually in the design stage. The main aims of this study were to assess various combinations of materials using BIM and identify alternative, sustainable solutions to reduce operational energy consumption. The amount of energy consumed by a double story bungalow house in Johor, Malaysia, and assessments of alternative material configurations to determine the best energy performance were evaluated by using Revit Architecture 2012 and Autodesk Ecotect Analysis software to show which of the materials helped in reducing the operational energy use of the building to the greatest extent throughout its annual life cycle. At the end, some alternative, sustainable designs in terms of energy savings have been suggested.

Scientists have progressed a lot in their capability to produce substances from available materials. Nanotechnology could change the construction sector by creating new materials and providing new building technologies such as energy efficiency in the buildings and also a new technical tool which can modulate the climate changes and help us to mitigate the green house gases emissions in the future. It helps the construction sector to improve new products, and to significantly enhance the material quality. The field of building materials has had its most improvement in the characteristics of concrete, steel, glass and insulating material, including resistance, durability, reduction of pollution and etc. Generally the main causes of pollution produced in the construction field are related to the producing of different construction materials. So by using nanotechnology in materials and improving their performance, pollution in materials production will be mitigated. On the other hand, in recent years, in spite of many efforts in developing the technology by using these materials, few of them have dealt with the ecological cycle due to applying them. However, during utilizing a new technology, the negative aspects and consequences should also be considered to help us to seek ways to resolve the negative impacts. In this paper, a synopsis of the application of nanotechnology and nano-material in the construction industry and also the negative aspects and consequences of nano particles which may have on living organism have been investigated.

Mazandaran is the name of a region located at the north of Iran with a mild and humid weather with high raining. The natives of this region like different regions of the word have achieved the most optimal form proportional to the climate over time, which has devoted a great portion of identity indication of this region to itself. People of this region where a mild and humid weather has, have used natural forage as a pattern in their roofs which is applied as green roof today. This green roof pattern in Mazandaran has been converted into green earthen roofs during its evolutionary steps. Green roof can be known as the result of a positive environmental, ecological procedure which attempts to balance the surrounding environment to decrease the load of abnormal environmental factors. The obvious and hidden positive effects which the green roofs in this region possess, have changed it into a unified factor in all buildings of Mazandaran. The main issue of the paper is written regarding to the survey researches, the study and recognition of different kinds of steep roofs in Mazandaran and its evolutionary direction and the effects which it has on the buildings of this region. The hypothesis of this paper is that there are equal semantic definitions in some components of building in mild and humid regions of the word but the method of facing with these components is different according to the culture of each region. Green roof in Mazandaran region has a different body but the equal meaning as like the other regions of the word.

High cost of primary requirements for constructing the houses in places on where people are under poverty line, is forming one of the most significant problems of people. On the other hand, urbanization growth will increase rubbish especially non-renewable ones. A suitable approach for this situation is using some part of urban rubbish as required materials for building construction and also providing comfortable situation and suitable thermal for building residents. Plastic bottle is considered as an urban junk with sustainability characteristic which can be used as a material instead of some conventional material such as brick in building construction. This paper intends to investigate the application of plastic bottles as one of the urban wastage in buildings construction and that how it can lead to sustainable development. It also mentions some ways for self-standing and insulating them in thermal and sound points of views and some positive points which this material have versus others. At the end, it concluded that in different factors such as time of execution, cost, load capacity, flexibility, reducing waste and energy efficiency, plastic bottles can be more effective compared to some conventional building materials such as brick, concrete and ceramic block.

The goal of this paper was to propose an external wall using a sustainable and innovative product with considering some factors, such as lack of energy waste, saving rainfall water, planting some plants in Isfahan located in central Iran, which has a semi-desert climate. This wall and a proposed product will create clean and pleasant air surrounding the building using the vegetation cover in addition to help for achieving comfortable temperatures inside the building. This paper consists of three steps, i.e., 1) selection of the most appropriate kind of insulation of external walls; 2) selection of the most appropriate kind of windows with minimum thermal losses, and 3) installation of the proposed product on the external wall and evaluation of its environmental effects inside and outside of the building.

This is known as one the first human actions for sustainable development. The ways that natives of each region have used to create an environment for developed life over the years. These methods have also become the culture of the region besides improving the lives of native people and have created a sense of belonging for them. Hence, green roofs are considered as one of the first and oldest of these methods. The green roofs can be built in different ways according to the place being used. These methods were specific to places that could be created based on native plants, materials available, and the culture of the region. The green roof technology can be considered as a solution for today’s poor environmental conditions of cities through reducing greenhouse gas, improving human health, and ecosystem. This book investigated the traditional green roofs in different regions of the world and also different impacts that these kinds of roof can have on the surrounding environment. This book aims to create a scientific background for the use of local pattern of each region as a potential solution for the problems of the region and the similar regions through introducing modern and traditional green roofs. Results and investigations can prepare grounds for researchers to express their ideas to build new green roofs.
1. Introduction
Usually everything around human is called environment [1]. The environment is consisted of a set of data that create reality. Set of perceptions that human acquires from the fact, forms objectivity. Objectivity varies in different humans. Different people can have different perceptions from environment.
Mental constant is a factor that contributes objectivity to be unit in a group of people. Having understood the environment and created objectivity humans will adapt it with their mental constant. In addition, whenever this adaptation happens, identity and sense of belonging will take place in the person. Unlike its name, mental constant can be composed of all the human senses. Perhaps a certain type of sound, smell, contexture, or view would remind a common message for a set of human beings that would not mean the same for others. Nevertheless, it can be said that we create a series of schemas or key words in mind when we are dealing with the environment, and we remember the event with reference to these key words. There are factors that bind us with the environment and culture. These factors are called environmental mechanisms which is consisted of a set of specific culture environmental factors (manufactured and non-manufactured), or taken from a culture, which human recognizes it as a symbol or sign. Each area has specific and clarified elements of culture and identity that have been developed throughout the history. A history that continually expresses these symbols as its particular identity, like the fingerprint of a person.
To create a new construction, considering spirit of the place was of high importance in traditional context of each region. Each place, as a living organism, has its own unique spirit that manufactured building, as new data, should be able to exchange information with the old data. New manufactured buildings’ non-compliance with the spirit of the place can make the place a sick existence that its organs are incompatible with each other and with its nature.
Different construction cultures through many years according to different reactions of people to their climate, regularly will become a symbol for that region.
As a result, the geographical location of that place will be recognized with these symbols. In addition to the physiological comfort which these symbols cause in the climate, it also creates a sense of belonging to the inhabitants of this region. It prepares the inhabitants for displaying consistent behaviors with the norms of the region as well. Due to the reason that people observe the same codes and sings in their private homes (with all those memories and backgrounds), they can also observe them in a larger scale of neighbor, neighborhood, and city.
As a result, in a larger scale, they do not consider themselves outside of their own home. Therefore, the same sense of belonging, which is the cause of peace, providing service, and controlling their own home affairs, will make sense in a scale larger than home.
