Double envelopes, also known as double facades, are building facades with multiple layers or skins. They are used to maximize daylighting while controlling solar gain and temperature. There are four main types of double envelope configurations: box windows, corridor facades, multi-story facades, and shaft boxes. Double envelopes provide benefits like increased insulation, natural ventilation, and shading/sun control. Their performance must be considered in the context of a specific building and climate. Case studies demonstrate how double envelopes allow interior control of light and views while providing energy benefits.

Façades in South-East Asia are well understood using typical performance metrics such as ETTV.
Using the centre of pane performance values of shading coefficients (SC) and U-values, we can get a feel for the performance of façades but can these truly be determined as high performance if the conductive elements (thermal bridging) of framing and shading details are ignored?
This presentation aims to illustrate the case for higher performing façade systems and hopes to be of value for those looking to fully integrate the design of such systems in South-East Asian commercial buildings. It is also aimed at those looking to understand façade framing performance and testing, to gain a greater knowledge of façade detailing and performance.
Sustainable Design Part Two: Climate Related IssuesTerri Meyer Boake
What is Sustainable Design Part Two: Climate Related Issues looks at the bioclimatic regions and how they affect the approach to environmental building design. This also looks at the comfort zone as a way to reduce energy consumption.
The façade type closed cavity facade (CCF) avoids the pollution of its inside surfaces as it is not exposed to ventilation. Condensation is suppressed with the supply of dried air to the inside, but the amount is very low, as the unit is constructed to be almost air tight

Impact of Climate and Environment Changes on the Sustainability of the Coastal Areas: The Case of Ain Sukhna, Red Sea, Egypt
This paper investigates the impact of climate and environmental changes on the sustainability of the coastal area of Ain Sukhna, Red Sea, Egypt. Ain Sukhna sea shores and Galala mountain region have witnessed rapid change and modifications during the past 50 years. Climate changes are expected to impact this area through the increase in the amount and intensity of rainfall and the rise of seawater tides. Modifications applied to the topography of the mountains through grading and levelling are spreading excavation debris on the sides of the mountains creating a new hazard if swept away by the rainwater. The paper analyzes the design and construction of the coastal and mountain developments and assesses their capacity to withstand these changes. The negative impact of these changes is not only ecological but also physical and socioeconomic. Climate change impacts are becoming more instantaneous and intensified. Place-based strategies for reducing the negative impact of climate change are required to reduce the physical and ecological vulnerabilities and manage the impacts of climate change.

Typologies of Urban Development in Sukhna-Zaafarana Area.pdfGalala University
Development of Sukhna-Zaafarana stretch went several forms and intensities during different periods of time. It is currently witnessing another wave of rapid development resulting in more stress on the natural and urban environment. This paper analyses the typologies of its urban development and their resilience to potential risks of climate change using urban design techniques to analyze the area in terms of character, continuity and quality of the public realm, ease of movement, legibility, adaptability and diversity. In addition, the research analyzes the different natural sites, such as the shoreline, the floodplains, the Galala mountains, and the valleys. Methods used in this study included: survey and analysis of the built and natural environments based on maps and site visits; and SWOT analysis to identify the potential risks and challenges in the area. Maps and tables of typologies based on the date of construction, environmental characteristics, neighborhood planning, architectural design elements, urban design features, landscape design, greenery, and water features are produced. The results of the study indicate the absence of visual connectivity, architectural identity, public services and facilities, and overlapping vehicular and pedestrian circulation. Moreover, the built environment is vulnerable to climate change risks, since most structures on the coast are built either close to the shoreline or on floodplains, hence threatened by sea-level rise and extreme flush floods respectively. The study concludes by suggesting a set of urban design guidelines based on the three principles of sustainability; environmental, economic and equity to achieve a more sustainable and resilient environment.

AI-Human Dialogue for Architectural Design Concept Generation presentation
Architectural design concept generation is the process of coming up with the initial ideas for a new building or structure.
It is an essential part of the architectural design process, as it provides the foundation for the rest of the design.
AI-human dialogue for architectural design concept generation is a process where an architect and an AI system collaborate to generate architectural design concepts.
The AI system can be used to:
Generate ideas: The AI system can be used to generate a wide range of design ideas
Evaluate ideas: The AI system can also be used to evaluate design ideas. This can be done by considering factors such as functionality, aesthetics, and sustainability. This can help the architect to make informed decisions about the design.
Collaborate with the architect: The AI system can also be used to collaborate with the architect. This can be done by providing feedback on the architect's ideas or by generating new ideas based on the architect's input.

Editor's Notes
In terms of thermal insulation the double envelope is known as This means that The shading device within the double envelope absorbs the solar gain and re-radiates it in the cavity
As we hav mention double envelobe are used to maxmize daylight while controling solar gains which is tipical in office blding \ And int his pictures these operable shading devices
Since the double envelope reduces the temp of the interior skin, it reduces the overall mechanical intervention (cooling equipment) in turn lessens energy use Night time ventilation: During the hot summer days, the interior spaces can easily be overheated. In this case, it may be energy saving to pre-cool the offices during the night using natural ventilation. The indoor temperatures will then be lower during the early morning hours providing thermal comfort and improved air quality for the occupants.
Box windows: self contained with air intake and exhaust ports for cavity ventilation. (natural convection) , punched in , great for privacy and high noise level
the surface temperature of the inner glass is kept close to room temperature, leading to increased occupant comfort in the perimeter zone, near the facade. This type of facade is recommended for cold climates, because of the increased comfort during the cold season and the possible recovery of solar energy.
Done to maximize usable floor area The outer glass leaf is suspended beyond the edge of the primary structure. Fire escape: The glazed space of a Double Skin Facade may be used as a fire escape.
Cavity is ventilated through large openings at the base and parapet. (natural convection) Lighter as opposed to heavy 80’s shading systems
Architects should keep in mind the points that they can get for implementing green strategies These are the three main categories, double envelope strategies can achieve in
We should keep in mind the maintenance requirements of the double envelope: In utilization we must be aware that the…. Other maintenance requirements include Maintaining ventilation controls Cleaning inside the cavity
If this operable glass can provide access to each façade unit, the depth can be greatly reduced for efficient maintenance and material considerations. North America: fixed insulating glass on the outer leaf with a hinged plate of glass added to create a thin double envelope. Heat absorbed is removed by drawing out the stale air.
Large-scale vs significant floor area underutilized: Cost comparisons must take into account the maintenance factor Acoustic insulation: In view of some authors the sound insulation can be one of the most important reasons to use a Double Skin Façade Effective double envelope applications are sometimes actually Poor energy performers
Corridor multi-story Transparency/ architectural design: In almost all the literature, the desire of the architects to use larger glazed facades is mentioned.
