DESIGN PROPOSAL

1. INTRODUCTION 1.1 SUMMARY This report is an outcome of the term 2 Refurbishing the City part II project of the MSc-MArch Sustainable environmental Design program, 2021-2023. Our aim for this term was to utilize the tools and analytical knowledge taught to enhance the environmental performance of the building and its surroundings. Understanding the demographics and the context played a vital role in structuring our design, followed by an attempt to achieve thermal and visual comfort for the users. Various passive design strategies were introduced in order to reduce heating load during winters and avoid overheating during summers. One of our major objectives was to achieve Net-zero carbon buildings with a detailed analysis of factors impacting the result like the properties of materials, compactness of the units, construction cost, etc. The site is located in the Battersea district, of Wandsworth borough, by the river Thames. The aim is to develop a housing project of affordable homes in the Battersea area. The report is structured in several parts, starting with a general overview of the site, understanding the climatic context. The report further moves into articulating a design proposal. This took into consideration the COVID situation, resulting in work from home spaces and other open green spaces for the health and well-being of the occupants. The idea was to create a strong sense of community for the people of Battersea. The report further dives into a series of indoor and outdoor studies, which involved daylight, wind, and thermal simulations which helped mold the design, keeping in mind occupancy comfort along with increased efficiency and environmental performance of the building. The main goal was to combine all the above aspects to create energy-efficient homes, taking into account the limitations and opportunities that the site has to offer along with our term 1 knowledge to optimize the performance of the building and create experiential spaces for the community of Battersea.

2. OVERVIEW 2.1 SITE INFORMATION The site is situated on the south bank of River Thames in Wandsworth Borough, with an area of 5993 m2, latitude of 51.4 N, and longitude of -0.17 W. Having a varied history of social housing Battersea has a large area of public housing states dating from the 20th century. The site connects the districts of Fulham and Chelsea (north of the river) to Clapham district (south of the site) and is accessible from the Battersea bridge road. Specifically, it is placed between Battersea Park and the riverfront and the pathway is used by the neighbours for various physical activities, with Wandsworth London borough as the local authority. Being surrounded by a mixture of high-rise structures varying from 7-21 stories in the southwest part and low-rise buildings in the northern parts, the site acts as a transitional zone between the two. Currently, the site has one-story storage blocks along with a basketball court accessed by the neighbours.

These two roads connect the Somerset Estate (SW11 3NE) to the rest of Northern London, while the other minor routes on the East and West provide comfortable pedestrian access to the site. These streets are essentially 4m wide and one-way, namely Bolingbroke Walk and Sunbury Lane. Furthermore, the site also offers direct access to River Thames on the North.

2. OVERVIEW 2.5 FACADES AND MATERIALITY Most of the recently built high-rise residential buildings in the surrounding context have higher glazing ratios and balconies in order to provide suitable views of the River Thames as evident in North-Acre Residence, Marsdex Apartments and Selworthy House. However, the predominant low-rise residences follow a more traditional scale of windows, along with few instances of glazed balconies. In addition, the material palette is primarily dictated by brick with tones of reds and browns.

2. OVERVIEW 2.6 ON-SITE IMAGES 1. BASKETBALL COURT The court is being currently used by the people of the surrounding neighbourhood; however, no proper provision is available to host a public gathering for the matches conducted if any. 2. PROXIMITY TO THE STREET A major part of the site is occupied by storage garages, it is the least overshadowed spot by the surrounding buildings. Adaptation of design strategies should be done in a way, where proximity to the street is not ignored pedestrian or vehicle. 3. VIEWS TO THE RIVER As seen in the image, due to the presence of high-rise structures around the site, the views of the river are obstructed. Design strategies should be implemented in order to provide a view to future dwellers. 4. URBAN FURNITURE The park is empty and does not seem to be lively throughout the day. There is an obstruction to access the park which can be seen as a potential vital usable space if provided with well-designed urban furniture and landscape.

5. PARKING It was observed that this was a meeting point for the students during sun hours, around 2.30 noon, close to the bicycle and scooter parking. However, no adequate provisions like urban furniture, landscape are available for the comfort of the users. 6. RECYCLE BINS Currently, there are recycle bins present for disposal, that can be used by the existing community. In the future design, provision of a designated waste disposal area should be maintained, that can be used not only by the site users but also for people living around.

2. OVERVIEW 2.10 STRATEGIES FOR CLIMATE CHANGE

In meeting the challenge of designing for a different summer climate, we needed to extend our design skills and develop innovative technologies and products. For instance: 1. SHADING SYSTEMS for both new build and the existing stock that could be progressively rolled out as circumstances change. Deciduous trees and plants can provide beautiful,effective, low-cost shade that benefits from the process of transpiration to significantly enhance its cooling effect. 2. GLAZING AND FILM TECHNOLOGIES to improve the performance of glass in terms of solar exclusion. 3. The development of REFLECTIVE SOLID MATERIALS to reflect heat off of building surfaces. 4. Secure NIGHT-TIME VENTILATION SYSTEMS to allow buildings to be purged of hot air whilst also excluding insects. 5. High levels of INTERNAL THERMAL MASS COUPLED WITH NIGHT-TIME VENTILATION to minimise heat gains through building fabric, especially in lightweight constructions.

Figure 2.10.1 This table summarises the relationships between aspects of climate change relating to thermal comfort and opportunitues for designers, and gives an indication of the necessary timescale for strategies.

3. DESIGN PROPOSAL 3.7 UNIT TYPOLOGY WINDOW & BALCONY DETAIL The WFR (Window Floor Ratio) on the South-East and South-West facade is 20% with three variations in the window sizes depicted in Fig 3.7.1 as B, C, and D. This enhances the thermal performance during summers well as winters. In NorthWest and North-East facade, the WFR is achieved to have less ratio of 5% as per the functions in the unit oriented towards the facade and is depicted as A in Fig.3.7.1. These sizes and placements of the windows as per the orientation help minimize heat loss.

3. DESIGN PROPOSAL 3.7 UNIT TYPOLOGY WINDOW & BALCONY DETAIL Fig 3.7.2 shows the sun angles during the specified period, which helped us derive the balcony's overhang depth. The balcony can be treated as a conservatory for an improved thermal performance in winter. Fig 3.7.1 shows the one bedroom dwelling units and the function of the glazing in the balcony during the summers and winters.

Overhang 1.2M

1. Summer During summer, the sun's rays heat the glazed surface of the balcony, warming the air if closed. Therefore, for better comfort, the glazed balcony surface is retracted, creating openess in the balcony. Since, people open their windows more often for natural ventilation in summers, the adaptive nature of the balcony provides enhanced comfort.

2. Winter On the other hand, in winter, the sun's rays heat the glazed surface of the balcony, warming the air and limiting heat loss from the dwelling. Hence, improving the thermal comfort.

3. DESIGN PROPOSAL 3.8 CONSTRUCTION DETAIL One of the potential materials considered for the design proposal is Cross Laminated Timber for its versatility, structural rigidity, sustainability, and strength. In addition, the aim is to avoid thermal bridging and have flexibility in modular construction.Additionally, Glued Laminated Timber has been considered for the post and beam superstructure, while reinforced concrete is considered for the core and substructure. Fig 3.8.3 shows the material for substructure and core (Reinforced concrete), Walls (Cross Laminated Timber), post and beams(Glued Laminated Timber). Fig 3.8.4 shows the potential of cross-laminated timber in terms of span and height. It can span up to 8m and go up to 40m in height.

3. DESIGN PROPOSAL 3.9 CARBON ANALYSIS A material study was conducted on the building materials chosen to deduce the potential carbon footprint of the materials. The performance of Embodied carbon was studied with soft computation over FCBS Carbon Calculator. The study takes into account the carbon footprint of each and every material used within the project in various components of the building within its lifespan, with their respective volumetric quantity in cubic meters and how much each contributes to the saving of CO2. Alongside the material specifications at various stages of the building construction as shown in Fig. 3.9.1, the computational inputs provided for the study are as follows: Glazing ratio: 25% Storeys above ground: 12 Floor to floor height: 3 Grid size: 6m Building width: 10m Building footprint: 520 m2 Building perimeter: 116 m2 Gross Internal Area: 5730m2 The computation results follows estimate of life cycle embodied carbon and biogenic carbon of various materials used in the components of the building. This study was conducted to give an idea of how the materials in themselves can help achieve carbon zero. Fig 3.9.2 depicts a typical 3 BHK unit in the building colour coded with the components of the building component’s materials in Fig 3.9.1. Additionally, Fig 3.9.3 depicts the life cycle embodied carbon within the different components of the building as a representative of the entire building’s proposal.

This is the benefit in carbon counting, as it gets subtracted from the rest of A1A3 as shown in the comparison graph in Fig. 3.9.8, where Case 2 has a smaller carbon footprint at the start of the life, as it already holds a large amount of carbon through its growing process. The graph helps in understanding that throughout the various stages of the carbon life-cycle as well, the case 2 proposal for the building proposes a low carbon footprint.

Cross Ventilation The narrow building and the unit depth ensure cross-ventilation across all the units. In addition, the corridors and the balconies are opened up for good ventilation to prevent molding and stale air to enhance good occupant health.

STACK VENTILATION

Stack Ventilation

TERRACE GARDEN

Double height units at certain building positions allow stack ventilation in the units allowing the lighter hot air to rise and the cool air to settle in the bottom. This strategy is also incorporated in the voids between the corridor and the unit, providing good ventilation and enhancement of occupant health. Solar Access Balconies are designed such that the sun enters units at all times of the year, however preventing excessive heat gain. Natural light is received from either side of the unit providing the occupant with good daylighting.

3. DESIGN PROPOSAL 3.11 ENERGY AND ENVIRONMENT RAIN WATER Rainfall amounts to 615 millimeters per year as per climate sources, and the perception as a rainy city is expected mainly to the frequency of the rains, which can occur quite often also in summer. Therefore, it is beneficial to use the roof surface of the building to collect the rainwater. The roofs can collect all the water needed for the inhabitant's uses (excluding drinking water) and the green spaces of the projects, which are the winter garden and communal gardens. As shown in the calculation the total area of 840 m2 of roof surfaces can collect 3,47,760 liters per year.

It is clear that London has the potential to generate more electricity from solar energy. Solar electricity panels, also known as photovoltaics (PV), capture the sun's energy and convert it into electricity that you can used.As shown in the calculation the total area of 840m2 of roof surfaces can generate 960KWh per day

4. OUTDOOR STUDIES 4.2 SOLAR ANALYSIS The solar radiation analysis on the facade of the building was performed by using the Grasshopper (Ladybug) plug-in software in Rhino 3D. Based on the latitude and the orientation of the building, it is the South-East and South-West facade that receives the biggest part of the solar radiation and daylight throughout the year. In order to maximize solar gain on the North facade, iterations were considered with experimentation with change in form and positioning of the blocks as depicted in Fig 4.2.1. Form 1 design iteration is considered with one bedroom unit block is placed on the south west. Form 2 is considered with the one bed room unit on the south east and form 3 was iterated with a change in the angle of the two bedroom unit block. Form 3 proves to the be the most optimized solution as it provides 13% higher solar radiation in comparision. The thermal simulation of units in the blocks, provides savings of 8% in annual heating demand in comparision to form 2 as depicted in Fig. 4.2.2 and 34% of the same in comparision with form 1 as depicted in Fig 4.2.3

An annual sunlight radiation analysis was performed on the developed form, as depicted in Fig. 4.2.4, Fig 4.2.5, Fig 4.2.6 and Fig 4.2.7. In Summer Period from May to August, there is a 45% reduction in Solar Gains due to the overhangs while in the Winter Period, there is minimal change of 12%. This is potentially due to the varying solar angles in both seasons.

4. OUTDOOR STUDIES 4.3 WIND ANALYSIS Ground Floor | LVL +5m

Wind simulations were carried out using Autodesk CFD software to visualize wind patterns and the airflow generated by the design proposal and on the surrounding buildings to ensure no severe wind disturbances were created. Based on data obtained by Central London Weather Station, the prevailing wind direction was set to Southwest, and the site has a major obstruction from the Selworthy tower. The study was conducted at three levels, the ground floor at Lvl +5m, the fifth floor at Lvl +18m, and the tenth floor at Lvl +33m, as depicted in Fig.4.3.2. Iterations were performed to conclude at the most optimum design decision for positioning the building blocks as discussed previously. The form of the buildings channels the strong Southwest wind from high-rise Selworthy Building to north and west directions, which gets stronger at certain curvatures. This influence diminishes, slowing down the wind at the inner parts of the site. As observed from Fig 4.3.2, the wind velocity is reduced further when the design proposal is in alignment with the Selworthy house as it behaves as a wind barrier. Hence, form 3 provides higher occupant comfort. First, on the pedestrian level at Lvl +5m, the wind analysis was conducted to understand how to organize the exterior spaces and confirm the building shapes. Then, the wind speeds were calculated at Lvl +18m, where the communal spaces are present. However, due to the change in angle in Form 3, there is a reduction in the wind speeds making it more comfortable. Finally, on top of the tower, at level +33m, as there is a 360° terrace above, the wind velocity can become an issue.

The sizes of the voids dedicated for the communal gardens range from 3m x 3m to 6m x 6m. It is observed that the illuminance levels range from 3000 - 4500 lux during the summer months and that in winter ranges from 1000-3000 lux. These illuminance levels are adequate for performing activities in an outdoor space.

5.1 DAYLIGHT ANALYSIS 5.1.1 Daylight Factor

To study the illuminance levels obtained for all the dwellings in the design proposal, a series of computational analyses were carried out using parametric tools on Grasshopper using Radiance plug-in. Based on the resources obtained from the Wandsworth Borough Coucil regarding daylight, the minimum Annual daylight factors necessary in a dwelling are as follows:

1 BHK | Type A Living 1%| Bedroom 1%

Living Room - 1.5% Kitchen- 2% Bedroom- 1%

1 BHK | Type A Living 3% | Bedroom 1% 1 BHK | Type B Living 5% Bedroom 3%

The study was performed for the dwellings on level 5 and level 10 in order to conclude the difference in daylight based on dwelling height. The following factors were provided as inputs for carrying out the analysis Windows Double Glazed | Visual Trasmittance : 0.70

2 BHK | Type A Living 3% | Bedroom 2%

2 BHK | Type A Living 2% | Bedroom 1%

Balcony Single Glazed | Visual Transmittance: 0.89

2 BHK | Type A Living 2% | Bedroom 1%

Walls CLT With Plaster Finish | Reflectance: 0.8

3 BHK | Type B Living 7% | Bedroom 2% 2 BHK | Type A Living 4% | Bedroom 2%

Floor And Ceiling CLT | Reflectance: 0.3

Fig 5.1.1.1 depicts the Annual Daylight Factor received by the dwellings on Level 5 of the building. The block facing North-West and South-East receives the recommended minimum daylight factors in the range from 1-3% in the dwelling's spaces. However, the 1 BHK dwellings facing North-East and SouthWest direction have a daylight factor of around 1%. Fig 5.1.1.2 depicts the Annual Daylight Factor received by the dwellings on Level 10 of the building which is comparitively higher than that of the lower levels. The block facing North-West and South-East receives the daylight factors in the range from 2-4% in the dwelling's spaces. However, the 1 BHK dwellings facing NorthEast and South-West direction have a daylight factor of around 3-5%. The dwellings which consist a living room of a double height receive larger daylight due to larger number of fenestrations on the facade.

5.1 DAYLIGHT ANALYSIS 5.1.2 Useful Daylight Illuminance

1 BHK | Type A Living 80% | Bedroom 78%

Digital simulations were further carried forward to understand the useful daylight illuminance in the space annually. The percentage of daylight received annually in the useful range from 100-2000 lux with consideration of glare and without the need for the use of artifical lighting during the day is accounted for in the analysis. The results observed are depicted in Fig.5.1.2.1 and Fig.5.1.2.2 for the 5th and the 10th floor respectively.

1 BHK | Type A Living 69% | Bedroom 77% 1 BHK | Type B Living 65% Bedroom 76%

The percentage of useful daylight ranges from about 75-80% annually in the dwellings on the 5th floor and that on the 10th floor ranges from 60-80%. This adequacy in the amount of useful daylight illuminance allows the occupant to experience visual comfort throughout the year.

As seen in the previous graph, figure 5.2.2.1 shows the indoor temperatures of the one-bedroom unit, however, it is observed that without the presence of a glazed balcony during this time there is a decrease in temperature by 20C due to the heat loss from the exposed rooms. Figure 5.2.2.2 shows heat gains and losses through different parameters involved in the process.

Figure 5.2.3.1 shows hourly indoor temperatures for a typical winter week dated from 1st to 7th march. It is observed that for a maximum outdoor temperature of 90C the temperature fluctuations for the glazed balcony are reaching up to 260C on one of the days in the week. This is due to the orientation of the onebedroom apartment blocks. It is also observed the indoor temperatures of the living and bedroom are significantly lower than the comfort zone temperatures, which would be improved with further iterations to the design strategies. Figure 5.2.3.2 shows the heat gains and losses by different parameters involved. It is observed the maximum gains to losses is through windows, which cover 20% SECTION 01 of the window to floor area.

Figure 5.2.4.1 shows the graph depicting hourly indoor temperatures for a typical winter week. After looking through various iterations, a solution case was developed, which involved the unit having retractable balconies along with night shutters and blinds of 40% transmittance which helped decrease the heating load to a significant 30% than the base case heating load. Although heating was introduced, the different parameters like the night shutters schedules, occupancy patterns, the relation of the outdoor temperature with the indoor helped reduce the heating load to 0.05 KWh/m2 Annual heat gains and losses from different parameters for this case can be seen in figure 5.2.4.2.

Figure 5.2.5.1 shows hourly indoor temperatures for a typical summer week dated from 7th – 13th July. It is observed that in the presence of a glazed balcony the temperatures on a free-running mode are well within the comfort band. However, the whole idea is to have adaptive strategies and these balconies are designed for the user’s benefit, and the occupant can choose whether or not to open the balcony according to the changing outdoor conditions.

Figure 5.3.3.1 shows hourly indoor temperatures for a typical winter week dated from 1st to 7th march. It is observed that for a maximum outdoor temperature of 90C the temperature fluctuations for the glazed balcony are reaching up to 240C on one of the days in the week. This is due to the orientation of the twobedroom apartment blocks. It is also observed the indoor temperatures of the living and bedrooms are significantly lower than the comfort zone temperatures, which would be improved with further iterations to the design strategies. Figure 5.3.3.2 shows the heat gains and losses by different parameters involved. It is observed the maximum SECTION 02gains to losses is through windows, which cover 20% of the window to floor area.

Figure 5.3.4.1 shows the graph depicting hourly indoor temperatures for a typical winter week. After looking through various iterations, a solution case was developed, which involved the unit having retractable balconies along with night shutters and blinds of 40% transmittance which helped decrease the heating load to a significant 30% than the base case heating load.

35 35

Although heating was introduced, the different parameters like the night shutters schedules, occupancy patterns, the relation of the outdoor temperature with the indoor helped reduce the heating load to 0.58 KWh/m2. Annual heat gains and 02 losses fromSECTION different parameters for this case can be seen in figure 5.3.4.2.

Figure 5.4.1.1 shows the annual hourly mean indoor temperatures predicted for the two bedroom apartment. The following simulations indicate the months of the year that are underheated and would require strategies to achieve comfort temperatures that are ranging from 19 to 25 degrees for the winter and 21 to 27 degrees for the summer. Figure 5.4.1.2 shows the annual heat gains and losses by different parameters involved. The bedroom chosen for the simulation was at a height of 18 meters from the ground level and it was observed that there is a minimal difference of 0.50C to 10C with the indoor temperatures for the apartments at the topmost floor.

Figure 5.4.5.1 shows the graph depicting hourly indoor temperatures for a typical winter week. After looking through various iterations, a solution case was developed, which involved the unit having retractable balconies along with night shutters and blinds of 40% transmittance which helped decrease the heating load to a significant 30% than the base case heating load. Although heating was introduced, the different parameters like the night shutters schedules, occupancy patterns, the relation of the outdoor temperature with the indoor helped reduce the heating load to 0.16 KWh/m2 Annual heat gains and losses from different parameters for this case can be seen in figure 5.4.5.2.

Through the analysis of thermal comfort for a one bed room unit oriented northeast and south-west direction as depicted in Fig.5.6.1.6, it was evident that with addition of a glazed balcony, the performance of the unit was enhanced. Additionally, with the introduction of mechanical heating in a mixed mode, the performance is enhanced towards the comfortband. The performance was further analysed for indoor microclimate in the unit using the ladybug plug-in for grasshopper in the typical winter(1st- 7th March) and summer week (7th - 13th July) considered for the analysis. Fig 5.6.1.1 depicts the temperature around 9-12oC, which then changes to range between 12-18oC with the addition of the glazed balcony as depicted in Fig.5.6.1.2 as it creates a winter garden and helps capture of heat. A mixed mode comfort with addition of mechanical heating affects the unit and provides a operative temperature around 18-20oC as depicted in Fig.5.6.1.3 providing comfort to the occupants.

Through the analysis of thermal comfort for a three bed room unit oriented north-west and south-east direction as depicted in Fig.5.6.3.6, it was evident that with addition of a glazed balcony, the performance of the unit was enhanced. Additionally, with the introduction of mechanical heating in a mixed mode, the performance is enhanced towards the comfortband. The performance was further analysed for indoor microclimate in the unit using the ladybug plug-in for grasshopper in the typical winter(1st- 7th March) and summer week (7th - 13th July) considered for the analysis.

5.6 INDOOR MICROCLIMATE ANALYSIS 5.6.3 Three Bedroom Unit

The summers provide an adaptive opportunity for the balcony glazing to be opened up based on user's requirements. Hence, on this basis, the operative temperature ranges in the comfort band from 20-24oC in either case as observed in fig 5.6.3.4 and fig 5.6.3.5. The argument holds true in the case for the units that the performance is enhanced during the winters with the addition of a glazed balcony due to its effect as a winter garden helping in capturing heat. The summers provide an adaptive solution allowing the occupants to change as per the requirement. Hence, utilizing passive design techniques to enhance the building's performance.

7. CONCLUSIONS 7.1 GENERAL CONCLUSIONS Term 2 was indeed a very interesting and challenging experience for us. Taking into consideration the lessons from the previous term, and using these tools as a part of the design process, the team was able to make better design decisions. We started by analyzing the existing proposals and the context to get a better picture of our design in terms of orientation, morphology materials, connectivity, open spaces, etc. Our previous term tutorials in terms of analytical work helped us understand optimizing sustainable features as architects and integrating these strategies in our design. After analyzing the site well, we started looking into different possibilities that could pan out by using computational tools. Designing various types of dwellings, taking into account the demographics and the occupancy schedule was one of the first steps. Taking the pandemic into account work from home spaces along with green open spaces for health and well-being were also proposed. Optimizing solar access without causing overheating during the summers through the orientation and other aspects was also detailed. One of our main design features was the adaptive approach of retractable balconies for different times of the year. The idea was to make it user-friendly and make changes as needed. We aimed to achieve net-zero carbon building through a detailed study of various elements in terms of materiality, depths, and heights of the unit was also a part of the design process, creating experiential spaces for the users along with enhancing the performance of the building.

7. CONCLUSIONS 7.2 PERSONAL OUTCOMES Ayushi Gupta

Ketan Naidu Kunapalli

Tanvi Patil

Deepthi Ravi

The opportunity to design the Battersea Church Road Development project provided me with a better insight into the complexity of sustainable environmental design and the role various elements comprising a space play in creating a thermally efficient and comfortable environment.

Term 2 project has allowed me to study in-depth design principles for sustainable environmental design, and the role of different elements composing a building in occupants' comfort has widened, and this term was an extension of term one in learning and gained more knowledge on design principles.

Working on a housing project like the one in term 2 has opened up many learning opportunities for me. The process of design has been an educational journey. Right from understanding the context and its needs to creating an experiential space, various architectural aspects came into play. One of the key factors was to understand who we are designing the space for and the functions required accordingly. This helped us get a vision of how the spaces would articulate as a whole. Moving to the computational tools that were taught to us during the first term, like studying the daylight or the wind patterns and optimizing them, we were able to induce these skills, which played a major role in enhancing the performance of the building in terms of orientation, the morphology, indoor thermal performance of the units as well as the microclimate of the surrounding area.

The project provided the opportunity to understand the integration of environmental factors into architectural design. The perception of being able to think critically and use features of passive strategies for the design at the initial stages to dictate the design was intriguing. It was a very informative and challenging journey to align the design process with substantial data on the site context and previous proposals and analysis the optimum solutions through the computational tools learned previously during the course.

In several ways, this project was both intriguing and challenging. First, trying to achieve net-zero design acquainted me with the importance of environmental constraints and material properties in correlation to the design process. The balance between the two proved crucial to several design decisions throughout the project. In addition, several simulations and computations like daylight analysis and thermal studies enabled me to understand the impact of different elements and solutions such as window to floor ratios, overhangs, and glazing properties on the layout. It was particularly helpful in developing different design strategies that could be valuable for various spaces in several conditions. Furthermore, throughout this project, I realized that it is not critical to use only sophisticated mechanisms, but even simple solutions and adaptive opportunities like opening windows could help achieve the required comfort levels. For example, in the case of the balconies, the use of glazed enclosures during winters to keep the apartments warm significantly impacted the thermal comfort while reducing energy consumption. In general, these analyses and studies widened my knowledge about eco-conscious designs and the importance of thermal efficiency while laying the foundation for further investigations.

Firstly, I mainly concentrated on designing from the concept massing to floor plans and units plans with knowledge on sustainable design principles, and it was challenging to incorporate the basic sustainable design strategies. In addition, wind analysis is performed to understand the impact of building orientation and improve the occupant's comfort by minimizing the wind chills and further work on design strategies to improve the thermal comfort. Secondly, a deeper analysis of existing studies helped me in the application of conservatories and balconies as a design feature. This feature had a significant impact on the thermal performance of the adjoining spaces, and the results helped to understand the spaces better. Design decisions were made based on the impact of several factors and was a continuous process. In Conclusion, this term was a great learning curve to understand how architectural design and sustainability work together. It gave me a more profound knowledge of how typical spaces perform under different scenarios and loads. The project is designed through the sustainability lens, which is good learning to take away.

Analyzing the existing proposals along with the proposals done by the earlier batch helped in structuring the whole project. Visiting the site also helped with better visualizations in terms of how the building would come up. One of the challenges we faced was working on the net-zero carbon buildings which made us dive into the study of materials, the compactness of the units, etc at the very initial stage, which lead us to make certain designs decisions. The idea was to improve the environmental conditions of the building along with making a design statement. Knowing that these aims can be achieved, if well analyzed was one of the objectives I would take from this experience. I would like to thank my teammates who worked and cooperated efficiently as a team to get the best outcome we could. It was interesting to collaborate and exchange various ideas and iterations that helped enhance the design and its performance.

The aim, however, was to provide adequate comfort to the occupants keeping in mind passive strategies. Therefore, the study of all simulations required patience and intelligence for inter-relation. Providing an adequate amount of natural daylighting into space but at the same time, controlling solar gains and internal thermal comfort was a task to look into. The simulations for the proposed indoor spaces to understand comfort at a microclimate level provided an understanding of the need for iterations in the window sizes and properties, balcony glazing operability, blinds, and shutters for enhancing the performance in the individual spaces in the unit. The performance of outdoor communal spaces in the public Daylight performance in the unit was carried out to understand that the units receive adequate daylight. Looking in-depth at the carbon analysis, helped me understand the means by which materiality plays an important role in the creation of a net-zero module using a design meant for disassembly through the massive use of cross-laminated timber in the building. One of the many struggles of a sustainable environment design is to be able to achieve a balance between user comfort and user needs. Ultimately, we have learned the basics of designing a practical and functional building that can help reduce energy consumption and carbon. Analytical and evaluation skills were strongly developed through this project which I further intend to utilize for all projects in the future.
