Existing Building Envelope
Existing Building Envelope
The building envelope serves as the interface between a building's interior and the external environment. Selection of appropriate building envelope is not only crucial to structural integrity and functionality of a building but also for its energy efficiency and sustainability.
The existing building envelope was constructed in 1970's and is in deteriorating condition now. Main feature of existing envelope and their cons are presented as under.
The existing blind wall on both side of the building and the blind portion between Plain Galvanized iron sheet have been treated with aluminum cladding. While aluminum cladding offers diverse range of design due to its flexible nature and shiny appearance but "Aluminum Composite Panels (ACPs) are flammable due to their polyethylene core and it is because of this combustible core that so many cladding fires have spread out of control" (Fire safe cladding).
While the dark brown Plain iron sheet offer contrast to building facade it also shows rust and fading color appearance.
The external beam column frame is exposed and have been treated with plaster only. The appearance is not very pleasing.
The external wall of projected portion is treated with plaster.
The external door and windows which leads to balcony at every floor are made of wood, the material has deteriorated and the glass between door and windows are broken. which presents pitiful condition.
In conclusion, the existing building envelope is not suitable for re adoption and maintenance due to several critical issues including fire safety risks, material degradation, higher maintenance cost, poor aesthetics, and lack of energy efficiency. In contrast to the proposed project the surrounding buildings including Mercedes-Benz Bank , Hampton / Hilton Hotel and Vision apartments have adopted modern, sustainable materials and design practices, resulting in safer, more attractive, and energy-efficient structures. while refurbishing the existing building upgradation of the building envelope to modern standards is essential to obtaining planning permission along with safety, sustainability, and visual harmony with its surroundings.

Proposed Building Envelope
Proposed Building Envelope
The proposed facade for the proposed building showcases a modern and sustainable design, integrating both aesthetic appeal and eco friendly features. Major exposed face of the building has been treated with energy efficient glazing. Granite marble stones will be used as finished material on blind wall portion of the building. This facade will add positive impact to the building surrounding, creating an eco friendly and sustainable place .
Here are some points highlighting different sustainability and aesthetic aspects of external building facade.
Energy-Efficient Glazing:
The extensive use of glass in the proposed facade promotes implementation of high-performance, energy-efficient glazing. This type of glazing minimizes heat gain during summer and heat loss during winter, reducing the building's overall energy consumption for heating and cooling.
It is recommended to use double glazed windows and Glass facade with U-values less then or equal to 1.3 W/m²K, according to "Minimum Energy Performance Requirements for Window Replacement in the 28 EU Member States" including Germany, the minimum requirements for windows is set at 1.3 W/m²K.
Natural Daylighting.
The large glass panels allow for maximum natural daylight to penetrate the building, resulting in reduction of need for artificial lightning during the day. This not only saves energy but also creates a more pleasant and productive indoor environment.
Ventilated Facade:
The proposed facade design supports a ventilated facade system, which will enhance thermal performance by allowing air to circulate between the building's exterior layer and the main structure. This will reduces energy consumption and will enhances occupant comfort.
Modern Aesthetics with Functionality:
The sleek and modern look of the proposed facade will not only enhances the building's visual appearance but will also serves functional purposes such as improved insulation and ventilation. This combination ensures that the building is not only beautiful but is also energy efficiency and sustainability in terms of performance.
Ceramic tile as facade material on some portion of building envelope has been proposed due to the reason that along with offering aesthetics and modern look, ceramic tiles also offer great resistance to extreme weather conditions and physical impacts. moreover along with durability, ceramic tiles are low maintenance as they are easy to clean.
while ceramic tiles have lower thermal resistivity its thermal performance is improved by external wall on which the ceramic tiles are resting. The cross section wall comprise of brick work as the main supporting membrane followed by insulation and internal block work, the block work is covered by a thick wooden sheet and plaster board is applied on internal most surface to provide a smooth face. This arrangement as shown in the picture below ensures a lower u-value as required by Building energy act in Germany. The ceramic tile add a layer of extra resistance to this value, which results in sustainable and energy conservative building envelope
Green Roofing
The flat roof of existing building offers space for installation of solar panels, a source of clean energy. Along with being eco friendly energy generation, it also offers cost reduction on energy spending. The flat roof will be utilized as Green roofs at the proposed building, which will provide insulation, reduce urban heat island effect, and support biodiversity. To lower u-values then 0.24 W/m2k , as required by Building energy Act of Germany for top roof, a detail cross section has already being explained, which will ensure efficient thermal performance.
Proposed Sustainability Features:
Proposed Sustainability Features:
Mechanical Systems including, Smart HVAC Systems, Energy Recovery Ventilation (EVR). Tankless Water Heaters and additional Systems such as , Low-Flow Plumbing Fixtures, Advanced Fire Protection Systems, Radiant Floor Heating, and Solar Water Heating System are the proposed sustainable features of the project.
Electrical Systems including ,Smart Lighting Systems, Energy-Efficient Appliances, LED Lighting, Advanced Circuit Breakers, Renewable Energy Integration, and Power Backup Systems along with, Low-Voltage Systems, EV Charging Stations and Energy Monitoring Systems are the proposed sustainable systems for the proposed project.
Sustainable features in Plumbing Systems for the proposed project have been incorporated through, High-Efficiency Fixtures and Appliances, Smart Plumbing Systems, Water Recirculation Systems, Eco-Friendly Materials and Grey Water Recycling.
Proposed step towards reduced carbon emissions and sustainability.
Proposed step towards reduced carbon emissions and sustainability.
Cost efficiency: The proposed sustainability features and use of high performance building envelope will ensure a cost and energy efficient design in long run. More over cost estimation, ghant chart and outlined detailed project program will keep the client inform in decision making, thus resulting in time , cost and resource savings.
Air Tightness: Small opening in the building envelope causes air leakage , resulting in raising the building's space heating or cooling requirement, thus uncontrolled leakage through gaps must be smaller than 0.6 of the total house volume per hour during a pressure test at 50 Pascal (both pressurized and depressurized). Which are 15 times more airtight than existing UK building regulations requirement. (Passive house institute .n.d.). such measures will restrict energy wastage.
Thermal bridge elimination: Reducing thermal bridges in a building increases insulation effectiveness, decreases heating and cooling costs, and advances long-term sustainability objectives along with prevention of structural damage. All thermal bridges must be less than 0.01W/m2K, known as a psi value. Thermal bridge elimination will result in effective energy utilization and eliminate unwanted carbon footprint.
. Solar Energy Gains: Proposed building envelope facilitate solar radiation to heat up building in winter season. This will result in lower enegy consumption during the long winter season in berlin. Moreover the proposed solar installation on building roof will generate green electricity thus reducing building carbon foot print. it is recommended to hire an electrical engineer to design an efficient solar system design.
