Summary This project presents the findings of the work done as part of the Term 2 project of the AA SED MSc/March programme, on the Royal Docks of the city of London. The brief developed by the team consists of a Promenade, a Restaurant and two blocks of buildings for Student Housing. Given the different background of the team during the first term, the process was developed from both indoor and outdoor perspectives. One of the main challenges of the project was the overheating that many buildings old and new have in London suffer due to the necessity to supply enough heat during the winter, which can lead to the actual overheating during the summer and even worse during the winter. As well as this, the provision of reasonable comfort in outdoor spaces was also tackled.

Introduction

Introduction The Royal Docks in the East part of London are currently under a long and difficult process of regeneration, as since, it was gradually abandoned after the 80â&#x20AC;&#x2122;s because of the shift in the needs of the trading market that gave it life in the first place, after the introduction of the metal container as primary unit serving the business and the big ships needed to carry them that wouldnâ&#x20AC;&#x2122;t fit in the docks. Many projects have been developed for Silvertown and the entire Royal Docks area, most of them satisfying the needs of the developers more than the end users. While at present, high densities and compactness are desirable by big cities, the necessity for quality public space has been relegated to a residual space complying just with the bear minimum regulatios. In the project this kind of space was proposed to provide the community with areas for family recreation, sports and leisure, that can be used all year round as they offer flexibility and adaptive opportunities to the public. On the one hand the Promenade which includes an outdoor GYM with different pavilions for each kind of exercise gives protection for different weather scenarios having wooden movable panels with adaptable louvers, that serve as well as a connection to all the different architectural elements of the brief, which also includes a CafĂŠ that doubles as an outdoor space for the summer and an indoor space for the winter, designed for casual users of the GYM, the sport facilities and the Student Housing also proposed to complete the strategies, considering the necessity of an anchor to produce a more plausible project. Learning outcomes from Term 1 and previous years projects where carried out as a start point for the design process, complemented by simulations with different pieces of software (TAS, Radiance and Ecotect, as well as the spread sheets and tools developed by the AA SED tutors team) to assess the thermal and visual comfort.

Royal Docks Census Data The Royal Docks has around 60% of its population employed, including working-students and according to the projections of 2050 that number will rise (Figure 7). The population of this site is primarily between 30-59 followed by young adults of 20-29 years of age and under 16. Thereâ&#x20AC;&#x2122;s a small percentage that include the elders and students between 16-19 years of age. (Figure 8) There is an equal balance of the sexes being 50% male and 50% female (Figure 10). It was important for the team to know what was the number of households in the site and we learned that 45.5% reside in a terrace accommodation followed by flats with 41.5%. Detached and semidetaches residences are less preferred by the occupants of the Royal Docks (Figure 9).

Figure 10 Population at Royal Docks (Source: www.ukcensusdata.com)

Silvertown Census Data The team then decided to look at Silvertown, since that it the location of our project to have a better understanding of that community. In this location there are 374 residents, being 172 male and 202 female (Figure 12) with 139 households to accommodate the 374 residents with an average household size of 2.7 (Figure 11) with a population density of 10.1 people per hectare in a 37ha area (Figure 13). At Sivertown, the total number of employed residents if 208 where the majority is working full-time and the number of unemployed is 24 (Figure 14). Acording to Figure 15, there are 62 residents that are economically inactive, most of them being students. Silvertwon is a very industrial area. The majority of the industrial sectors are for wholesale and retail trade, followed by accommodation and food services, education as well as financial and insurance activities. (Figure 18) The team believes that the future will rely more on public transportation and walking, so we felt a need to see what was the car or van availability in the area. On Figure 19, we can see that the majority of the residents do not own a car followed by just one car in a household. So, it was concluded that the community relies on public transportation and that will be good according to the projections of the future.

Weather Data & Climate Change

Weather Data Analysis PRESENT The weather data selected for the analysis of the project was obtained from the station located at London City Airport, using the Meteonorm and weather tools, making possible the obtention of yearly values for wind (Figure 22) , solar radiation, daily temperatures etc. That enabled us to stablish the Adaptive Thermal Confort Band specific to the site (Figure 21) and to assess the future performance of the buildings through simulation. The overall weather conditions of the site follow London’s general conditions with the known seasonal variations in solar radiation, rain and wind speed, all of this elements were taken into consideration for the design proposals developed.

Master Plan

2. Master Plan This Master Plan (Figure 41) programme is originates from two different backgrounds. On one hand two students focused their first term project on outdoor spaces and pavilions. On the other hand, two other students focused their first term research in housing apartments. The aim of this project is to combine both learnings of the first term research in one single project.

2.1 Observation

One of the main purpose of this project is to have a green space in the center and develop the project around it. The team decided to go to a park in London and analyse the activities and life style during the day (Figure 39). Clapham Park (Figure 40) was selected and we started a period of observation to find out which people occupied the park during different hours of the day. These observations allowed us to define the target of our site (Figure 38). This observation allowed us to understand the diversity of people that may occupy our project and that the students and young adults are the majority of occupants in the park.

2.2 Programme

The programme of this project consists of a outdoor wooden path, with controlled wind and light, which is fulfilled by a several number of experiences and sensations that end on a student housing (Figure 42). The path is developed in its length by different inclinations of louvers and roofs, which generate rhythm and different situations for people to adapt (Figure 43). The first stop of the path is one protected zone to drop off the bike. This area is placed next to the first building: the silo. The existing structure is a classified building with just a few windows in the facade. The team decide to choose a program for students and the community that fits with these characteristics, such as a grocery store, cinema, multipurpose rooms, top floor restaurant, etc. After passing the silo the visitors will arrive at the Outdoor Gym. This structure consists in a sequence of pavilions with different types of exercises. In the middle of these pavilions it is possible to find a quiet interior garden, for people that prefer to read or to relax. In the middle of the path, it is proposed a cafe. This equipment is an important element to connect people and to service the gym and the pool. Close to the cafe it is possible to access the pool and the outdoor showers. This facility also provides a relaxing zone, south oriented, with umbrellas to protect from solar radiation. Lastly, we have a play area with Ping-Pong tables and subsequently the path ends with a student housing building with 60 rooms and colective living rooms. Complementary to the path, the team decided to create three other zones. The first zone, located in the south entrance, shaped by â&#x20AC;&#x153;green dunesâ&#x20AC;? to protect from the wind and create a new dynamic landscape. In addition, we designed a concrete zone with tennis courts for students and external visitors. Finally, and as it was observed in Clapham Park, the team decided to leave a grass area in the centre, which can be used during the day by schools to practice football, rugby and cricket and in the afternoon by students and adults. Figure 42 Masterplan Programme

2.3 Alternative Paths The team proposes a dynamic wooden path to access our programme, but also provides different alternatives for people to choose. It is aimed that people can experience the main path, and at the same time have the freedom to change and come back from other alternatives ones. It is provided three other paths: The green path, the water path and the concrete path (Figure 43).

Outdoor Gym

3. Outdoor Gym The “Outdoor Gym” is composed by light wooden structures connected to the main path presented in the previous chapter. These structures aim to provide outdoor comfort in fitness activities and attract people that usually go to the typical enclosed gyms to these new outdoor equipments. Nowadays, the main alternatives to typical enclosed gyms are park gyms (Figure 44), which do not offer any type of specific protection. These park gyms are normally exposed to climate conditions and do not take into consideration the different seasons of the year. In what concerns physical exercise, it’s important to keep in mind that each exercise has a different metabolic rate and requires a specific microclimate to achieve outdoor comfort. The main questions raised by these design facilities are: (i) how to achieve outdoor comfort during the practice of fitness exercises in a London climate?; and (ii) how can adaptive strategies and flexible structures at a small scale provide outdoor comfort to fitness practitioners across the year? These questions will be properly answered in the design form. 3.1 Precedents The first step before starting the design process of the outdoor gym was Figure 44 Traditionelle Outdoor Gym Source: www.elgt.org.uk to look into the precedents studies and designs. The London Pier Gazebo (Figure 46) is an open program structure, mainly used as a place to take photographs of the views and to find protection against rain. The conclusions of the study demonstrate the importance of urban surroundings, especially for southern facing (the gazebo is not shaded only in the summer). In addition, the wind analysis allowed to conclude that openings in all four sides of the gazebo had a high susceptibility to wind and rain. The second example studied was the Vauxhall “gazebos“ (Figure 45). This project aimed to solve several problems, namely: the intensity of solar radiation, which is annoying during hot warm periods; the excessive radiation during late hours; the lack of connection in different zones of the park; and the turbulence created by southwest wind. Some of these problems were also identified in our Outdoor Gym project. The strategies applied in the Vauxhall “gazebos“ study were the following: rotating vertical panels with semi-transparent materials to filter excessive radiation during late hours; rotating panels facing west to protect from the wind to offer more possibilities both in warm and cold periods; use gazebos in different spots to connect different zones of the park.

3.2 Observation After studding the precedent work and learning from their conclusions, we started the observation process. The objective was to identify how people used the gazebos and which places were chosen to practice sports. To perform the observation process, the team selected the Clapham Park, since this is a flat park (as is the site of the project) and is used for different activities. In the gazebo observation (Figure 47), we found that parents and their children felt protected underneath the structure and that people enjoyed to practice exercises near the gazebo. In a second observation (Figure 48), we concluded that the path near the water was the most used one. According to our analysis, families and casual athletes tend to feel more confortable walking in this environment. To complete the observation process, we interviewed a personal trainer to better understand the requirements for fitness practice in outdoor spaces such as this. The team want to find out the needs of cardio fitness and the perfect conditions to practice it. Figure 47 Clapham Park ouverlayer - Gazebo

Figure 48 Clapham Park ouverlayer - Water path

3.3 Materials The main material used in our Outdoor Gym structures was wood (Figure 49). As we studied in previous works, this material has a positive psychological impact in the perception of outdoor comfort. In addition, wooden structures are warmer than other materials normally used in these outdoor facilities, such as concrete and metal. Indeed, with a wooden structure it is possible to increase the naturalness of the space. The louvers (Figure 50) of each gym pavilion were also made of wood and have a manual system to give users the flexibility they need to adapt to the climate. On the roof of each gym, a glass screen protected by louvers was placed(Figure 51); this design strategy will provide lighter ambience inside the pavilion when the louvers are nearly closed, avoiding a dark atmosphere. Furthermore, they will also serve as a protection from rain and other undesired climate situations.

3.4 Gym Plan Having studied how gyms work, and using precedents learnings, the goal now was to develop a gym with the required exercises, and set the gym as an independent path across the main path. In our Outdoor Gym (Figure 52), athletes can do several exercises, such as weightlifting, biking and rowing, and there are outdoor platforms for users to use as they like (Figure 53). The gym path is strategically organized to allow for a complete training and each gym pavilion is placed in a key point to ensure that the athletes can change from one to another in less then 50 seconds. As it is possible to see in the next section, the dimensions of each gym pavilion were carefully chosen to create a microclimate inside and to welcome small groups of athletes. Each pavilion is composed by two to five gym machines to do the same exercise. Users can start at the beginning of the proposed sequence of exercises, can choose their own order or simply practice randomly. Across the gym path, in order to achieve psychological comfort, the pavilions are surrounded by water and vegetation. Benches are also provided, for users to take a rest.

3.5 Gym design Taking into consideration the learnings from the previous sub-chapters, we moved forward to the gym design. The aim of this design, as mentioned earlier, was to achieve outdoor comfort in fitness practice across the year. The first strategy was to place relatively opaque panels to control the entrance of west winds inside the gym. The second was to select the size of each pavilion; sizes were selected to grant the necessary space for different types of exercises and, at the same time, to create a microclimate inside each pavilion. Lastly, to avoid a dark ambiance inside the structure and to protect from adverse climate conditions, glass screens, protected by louvers, were used for the roof. (Figure 54) These strategies seek to allow users to adapt to dockland climate. To help in this adaptation, we provide guidelines along the floors, for example, explaining how louvers should be turned and positioned at different hours and in different seasons (Figure 55). These guidelines were written taking into account studies presented later in this chapter.

Figure 54 Outdoor Gym 3D Renders Figure 55 Louvers guidelines

3.5 Performance of Gym and Comfort Analysis

To test the performance of the aforementioned design strategies, the team used multiple simulations, so as to achieve the desired wind inside the gym pavilion in the different exercise zones. We selected the simulations that offered the correct angle for louvers across the year, so as to obtain outdoor comfort during the exercise all along. In this subchapter we present the test runs we performed in three different gym pavilions, which correspond to three exercises: weightlifting (metabolic rate 3); biking (metabolic rate 8) and rowing (metabolic rate 5.2). the team performed the test runs to test the outdoor comfort of practitioners while exercising in hot, cold and mid seasons, taking into consideration the appropriate clothing for each period of the year. We present our tests below.

3.5.1 Weightlifting (Metabolic Rate 3) This pavilion has the lowest metabolic rate of the three examples (Figure 57). The two machine areas are exposed to multiple louvers orientation. As we can extract from the simulations, on the summer the most adequate louver orientation to achieve neutral comfort (Figure 59) during the exercise is around 60ยบ (Figure 58). On the other hand, in mid seasons the angle should be around 45ยบ (Figure 60) (Figure 61). Finally, in the winter the louvers should be closed (180ยบ) (Figure 62) (Figure 63) to avoid wind completely and achieve outdoor conform during the practice of weightlifting (Figure 64).

3.5.2 Biking (Metabolic Rate 8) Biking has the highest metabolic rate of the three examples (Figure 65). The five machines (Figure 66) are exposed to multiple louvers orientation. As it is possible to extract from the simulations, it is very dificult to achieve neutral confor. However it is possible to minimise the warmer state. Both summer season (Figure 67) and mid season (Figure 69) have a similar wind requierments (1.2 m/s and 1.1 m/s)(Figure 68)(Figure 70). With a louver orientation angle around 120ยบ, it is possible to archive slightly warm confort during the exercise in both seasons. On the other hand, on winter season whem the louvers are oriented with an angle of 105ยบ (Figure 71) (Figure 72) is possible to archive neutral confort in the top of the machine during the exercise (Figure 73).

3.5.3 Rowing (Metabolic Rate 5.2)

This pavilion has a metabolic rate of 5.2 (rowing) (Figure 82). The three machine (Figure 75) areas are exposed to multiple louvers orientation (Figure 74). As we can extract from the simulations, on the summer is dificult to achieve wind values of 1.4m/s, however it is possible to have wind of 1.1m/s. With 75ยบ louvers orientation (Figure 77) users will be between slightly warm to neutral comfort during the exercise (Figure 76). On the other hand, in mid seasons (Figure 78) and winter (Figure 80) the requierd wind value inside the pavilion to archive neutral confort is very similar (0.8m/s and 0.7 m/s). The louvers should be oriented in 105ยบ (Figure 79) (Figure 81). It is also possible to observe that, in both cases one of the machines will not preform as well as the other two.

Cafe

4. Cafe 4.1. Overview of the Cafe The team felt strongly about creating a space that could provide services for the pool, outdoor gyms and for those visiting the park, therefore there was a need to create a cafe area. This structure will provide a quick grab-and-go bar with indoor and outdoor seating, as well as restrooms ans showers for the visitors. Severeal tests and designs were studied and simulated (For more information on those tests please refere to the appendix). The cafe is intended to be interpreted as an indoor space during the winter, when it would be almost completely enclosed and outdoor space during the summer, where the glazing areas would be open creating a more outdoor feel to the space. The Figure 84 shows the location of the cafe on the masterplan and the Figure 83 is a more detailed image of the floor plan. Figure 85 shows how the shadow during Winter and Summer Solstices hit the building at 15h00.

Figure 85 Rendered images showing shadow during winter and summer solistices

4. Cafe 4.2. Precedent Study The project called “Living and working outdoors, vauxhall, London” from AA SED 2013 was studied and the design was taken into consideration when designing our cafe (Figure 86). The previous team had found that their location and orientation on the site may overheat during summer months, losses of heat during the winter if too much glass is used and may have a high wind speed due to lack of obstructions, which was very similar to our site. These concerns were taken into consideration when placing our cafe on the site and masterplan. The previous team concluded that good directionality and size of windows as well as shading devices would help with the overheating and heat loss problems. Their pavilion has a movable glass wall that would separate the left side of the structure forming smaller spaces in the cool period (Figure 87). The lower side of the roof is retractable to allow for solar access to provide warmth inside the space during the winter. One way the group found to resolve the problem of the wind speed was by sinking the structure just enough to avoid the wind gusts. The findings and understandings from this previous student project were very deeply thought about and helped the performance of the cafe that we are presenting.

Figure 87 Axon diagram of materials considered (Source: “Design of outdoor spaces:Vauxhall, London” AA SED Project 2013)

4. Cafe 4.3. Analytic Studies The cafe is a free running building, with the versatility of opening the glazing areas to provide a better comfort for the indoors. The bathrooms natural light comes from the windows located on the roof, allowing for the occupants to open and close it as they need, permitting that way cross ventilation (Figure 90). Because of its window to floor ratio of 85%, there was a need to set the windows to open when the dry-bulb temperature reaches 22oC both in the winter and summer, allowing this way a very comfortable temperature inside all year round. (Figure 89), shows the U-Values that were used for all the simulations. On (Figure 91), we can see how the louvers on the east facade operate. During the night they are meant to be located infront of the glazing area, in order to protect the space from undesired solar gains that happen during sunrise, and during the day it should be pushed back to allow the occupants to have a view to the water. Thereâ&#x20AC;&#x2122;s an occupancy schedule set from 10h00 to 20h00 with an average occupancy of 40 people.

4. Cafe 4.3. Analytic Studies As mentioned earlier, the cafe went through a series of simulations including Useful Daylight Illumination and Daylight Autonomy (Figure 93). The cafe area has a Mean Daylight Autonomy of 74.26% of time occupied for (Daylight Autonomy) and 67.60% of time occupied (for Useful Daylight Illumination)

4. Cafe 4.3. Analytic Studies When running the simulations the team took in consideration how it will respond in 2050. The cafe has a good response in terms of thermal comfort during the summer, as it can be seen on Figure 95 and Figure 97 as well as on Figure 100 and Figure 102. The team is designed this project to respond to the future, and by taking that into consideration, the way the cafe was designed will respond very well with the increase d temperature of 2050. (Refere to Figure 94 and Figure 96 as well as Figure Figure 99 and Figure 101 for that comparison). The team believes that this design is able to accommodate to future climate changes, giving this structure a longer longevity in terms of life time.

4. Cafe 4.3. Analytic Studies

There maybe times when the temperatures go above 22oC, but when that happens the windows will gradually open in order to keep a comfortable temperature indoors. (Figure 106 and Figure 107). The windows will open gradually, eventually reaching 100% opening. There are vents on all of the glazed areas that are open 24hrs, and this is to prevent overheating during the night and sunrise times. Due to the the window to floor ratio of 85%, there was a termendous concern about it overheating (Figure Figure 106 Aperture Flow In graph of a Typical Winter Week (2011) (Source: TAS) 104 and Figure 105) or having to much glare, therefore louvers were added to the East, South and West facades at 30o to protect the indoor space as well as double low-e glass on all of the glazed surfaces.

Figure 104 Solar Gains graph of a Typical Winter Week (2011) (Source: TAS)

The louvers play a very important role in the desing of the cafe. The occupant would be able to operate them so that a better comfort can be achieved according to the occupants needs. This interaction between human and building is very important and it can be seen throughout the entire project. The approach for 2050 is the same as is if it was 2011. The windows would still be set to open when the indoor temperature reaches 22oC, so it will not compromise the indoor comfort (Figure 108 and Figure 109).

4. Cafe 4.3. Analytic Studies The parameters used for the simulations in terms of internal gains can be found on Figure 117 as well as the appliances schedules on Figure 118. As it was mentioned before, the building is free-running, therefore it relies only on the internal and solar gains to provide heating for the space. Most of the gains are generated by the occupants, and by creating an enjoyable space, we can guarantee that it will be occuppied for most of the time. During the summer (Figure 114) thereâ&#x20AC;&#x2122;s a higher number of Solar Gains than in the winter (Figure 112), which is very important to understand. That was one of the reasons that drove the team to introduce vents and operable windows.

Comparing to 2050, what changes the most is the Solar Gains. The future of London is expected to have higher solar gains and a increase in temperature both in winter and summer. Lighting and Equipment Gains stay the same. (Figure 115 and Figure 116)

Housing

Introduction The growing educational demand of the city of London requires also housing for all the local and international students coming to the city each year. The Mayor of Londonâ&#x20AC;&#x2122;s office established the Mayorâ&#x20AC;&#x2122;s Academic Forum in 2011 to address the necessity to provide Student Housing without compromising the present house stock which many times gets overcrowded by students increasing rent prices. The mentioned document gives figures of a total of full-time students PhD and Undergraduate between 2011 and 2012 of 343,124 students, and predicts on the lowest scenario a population of 484,515 students by 2026 with annual increments of 9,436 students. With this numbers and the proximity to our site of the East London University, The Royal Greenwich University Tech London and the Ravensbourne Design and Communication College, as well as the personal experience of the team members who are aware of the high pricing of the rents and the difficulty to find appropriate accommodation, it can be concluded that the proposal of student housing as an anchor for the success of the scheme would benefit the entire project. Precedents from previous SED projects are analysed in (Figure 119).

Questionnaire The team questioned 60 students living in London to respond to a survey about their accommodations. The purpose was to find out the most common types of accommodation and how tese respond to the student’s daily behaviour. The responses were all given by full-time students where, closely to 80% are Master’s students, 20% are PhD students and a small percentage is undergraduates, as represented on Figure 121. It’s clear, from Figure 122, that the most common accommodation is the shared/flat type, followed by student accommodation buildings. In order for the team to have a better perception of the students’ lifestyle, they were asked if they usually go to school on the weekends, to which 63% said yes (please refere to Figure 120) The time graphs (Figure 123 to Figure 126), represent the times during the week when students are at school or at home. Most students arrive at school between 8h30 and 11h and leave after 15h30. Those that go to school on the weekends prefere to go a little later and leave earlier.

The most commons accommodations are either individual housing or shared between 2 to 5 people (Figure 129). There wsa a very low number of people that share with more than 9 persons. 40 people responded to this qeustions, and those that skipped it were assumed as living independently (Figure 127) The team wanted to know if the occupants were aware of the size of their bedrooms in m2, so that we could have a better understanting of what is common and how that can influence the future design (Figure 128). The most popular answer according to Figure 130 was between 11m2 and 20m2 followed by 0m2 to 10m2 (more specifically between 5m2 to 10m2) In order to better understand the importance of communal areas including kitchen and living areas, the team asked â&#x20AC;&#x153;how much time to you spend in communal areas...â&#x20AC;?. The response was not surprising due to the occupation of the people of answered it. Most people have access to a kitchen, living and laundry room which are only occupied between 30min to 3 hours a day (Figure 132).

and living?

Figure 132 How much time do you spend in communal areas everyday including kitchen and living?

Figure 133 Besides your room and bathroom to which of these spaces or services do you have access to?

Only a very small percentage has access to more luxurious spaces such as gym, communal areas and terraces. (Figure 133) Finally, the group asked how the occupants felt overall, about their living accommodations and it seems that most of the students are happy with their living arrangements. (Figure 134).

Figure 134 On a scale from 1 to 10 how satisfied are you with your accommodation? 78

Building Form The shaping of the Studio Unit (Figure 135) proposed for the Student acomodation building responds to the idea of the inclusion of PV panels in the facade, giving them the best performing orientation to south and tilting the front wall 45 degrees starting from a height of 2.20m, , (Figure 136) another key element is the design of the windows that responds to sun trajectorie through the day along the building and its occupancy schedules (from 12am to 10am and from 6pm to 12am) obtained from the survey previously described. The one on the south (Figure 137) facade with a South-East orientation in order to let the mornig sun in before students depart to school, and the back window (Figure 138) with a North-West orientation to admit afternoon sun at the return of the students during winter. A preliminary run of Daylight Autonomy (Figure 139) was performed using radiance to test the effectiveness of this strategyv. Obtaining levels avobe 75% percent of time occupied on both windows were the kitchen is proposed in the South-East one and the study space at the North West one. Further studies will be done to assess the thermal performance of this scheme.

Base Case Unit A theoretical unit and living room were proposed as a start point for the thermal and visual comfort studies to be carried out using TAS. As can be seen in (Figure 143) the resultant temperatures for the typical summer week rise as soon as the users get in the room and start using the equipment causing overheating at some points when the external temperature gets higher, making evident the need for a more effective natural ventilation strategy, while during the night the temperature drops and stays in the comfort zone until mid-day of the next day when solar gains get higher. On the other hand during the typical winter week (Figure 144)the temperature stays out of the comfort zone due to the drops in outdoor temperature during the night and the lack of internal gains during the day. Internal gains are described in (Figure 145), and the materials listed in (Figure 140). Living Room The base case livingroom due to its highly glazed area, its inadequate distribution to south and north and the lack of shading devices in the south facade presents overheating over 40 degrees during the summer (Figure 150) and temperatures below 10 degrees for long periods of time and overheating in some peak periods when solar radiation get unusually high during winter (Figure 151).Internal gains are described in (Figure 149), and the materials listed in (Figure 148).

Illuminance Yearly analysis. Illuminance studies where carried out through radiance for a typical unit and livingroom. (Figure 160) shows a typical plan for one floor of the west block of units and the localization of the spaces analized. Yearly values for Useful Daylight Illuminance between 100-2000 Lx, considering the spaces always occuppied to assess the light conditions througout the day were obtained showing results ranging from 23 to 40% of time occupied as can be seen in (Figure 154), Daylight Atonomy was calculated as well (Figure 155) with a target of 200 Lx with the same occupancy as UDI, resulting on values from 18 to 44% of time occupied. The kitchen and the desk inside each unit and the window to floor ratio of 22% were configured in order to have good access to natural light.

Illuminance Point in time illuminance. Illuminance runs for significant times according to the occupancy schedules of the building show that it has an overall acceptable natural light acces during the mornings before students usually go to school (Figure 158), (Figure 159), and during the afternoon once they come back during the summer (Figure 157). Mouvable louvered panels will be proposed for the south facing windows to provide users with adaptive opportunities whenever they are occupying the spaces during the day.

A window to floor ratio of 22% was established, proposing double glazed argon filled windows as a way to avoid overheating caused by undesired solar gain while maintaining good light levels. Careful attention was paid to the ventilation strategy designing a vent that will dissipate the excess of heat during the summer and improving the cross ventilation with a window on the north side next to the bed. The internal layout was improved moving the bathroom to the north side of the unit to give better light access to the study area and the kitchen, having the possibility to separate both spaces while cooking with movable partition panels. Internal gains are described in (Figure 164), and the materials listed in (Figure 163), along with the sections.

PV Panels Electricity Production Calculations. PV panels are proposed as the main renewable energy source for the building due to the mostly unobstructed access to solar radiation of the site and its south orientation. As explained in the Building Form section of this document the design of the scheme gives preference to the instalation of this system by giving a 45ยบ inclination to one section of the facade of each unit, 70ยบ for the livingrooms and the use of the promenade and cafe ceilings at 0ยบ inclination. (Figure 192) shows the analysis of the Annual Solar Radiation incidence in the surfaces covered in panels, making evident the areas not adecuate for this purpose as they are overshadowed by the Silo D listed building.

500

As seen in (Figure 193) a web based PV panel calculator by the UK Energy Saving Trust was used to calculate the amount of electricity generated by the system. An estimated 109, 532.55 kWh/yr value was obtained as result. Please refer to the apendix of this document for the full set of calculations. A comparison between the entire building consuption ( 60 Studio Units and 20 Living rooms) and the electricity produced by PV Panels is shown in (Figure 194).

Conclusions & Personal Statements

Conclusions GYM

The objective of this project was to continue the outdoor study of Central Saint Giles and the Pavilions. The aim of this project is to provide different microclimates in each pavilion, which allowed users to achieve outdoor comfort during the practice of their exercises. The big challenge of this design process is that each type of exercise has its own metabolic rate and requires a specific design. This reason obliged us to design each pavilion with a different size. One of the biggest challenge was to design for such a variety of exercises which required different outdoor comforts across the year.

CAFE

The cafĂŠ is a free-running building, requiring no mechanical heating or cooling, relying only on cross-ventilation and internal gains. While designing this project we had in consideration the future of London and how it will be in 2050, hence the fact that the cafĂŠ performs better then. The cafe is part of several stop along our path, and therefore there was a need to incorportate it, and that was achieved architecturally by keeping the same language of the louvers but also by allowing it to become an outdoor space when wanted. That way there is a sense of connection between the gyms (located west) and the pool (located northeast).

By adding vents and allowing for the glazing areas to open accordingly The strategy applied was to design a concept based which offer to the to the weather, permitted the occupants to adjust the structure as they user the possibility to adapt I many different situations. This strategy feel, creating an interaction between human and built form. consists in a system of flexible louvers that can be changed for each user. The architectural design of the building was also important, in the In order to help this process, it was designing some guidelines on the sense that it needed to be integrated with the surroundings and allow floor to help users to choose the correct angle in different periods of for views to the water, due to its prime location. the year. These design options helped us to answer the design research question of this chapter: how to achieve outdoor comfort during the Having a very big glazing area facing south the team ran into some practice of sport during the different seasons of the year? issues with overheating and glare as it was exppected, but that situation only made us work harder to find ways solve the situation.

106

HOUSING

The housing units started out as en-suite rooms with no kitchen, and the occupants share a communal kitchen in the living room. The indoor temperature for the units falls below the comfort zone during the winter. Therefore the team decided to make each en-suite rooms into studios with kitchen, which increased the internal gains and heat up the room. Although winter heating is still required, the internal gains reduce the heating loads to 19 kWh/mÂ˛ for the units and 12 kWh/mÂ˛ for the living rooms. This is to be compensated by having PV panels on the building and the roof of the promenade. Insulation is also a key, in the base case the building had double glazed glass with 2.8 U-Value, once the double glazed glass is replaced by argon filled glazing, the room temperature increased by 2Â°C.

Both the units and living room perform well in the summer. With natural ventilation and moveable louvers on the south side, the building stays in the comfort band throughout the summer in free running.

Having the building facing south gives the team a chance to explore the opportunities provided by solar access and hence the utilization of PV panels. There was a moment when the units are in risk of over-heating in the summer due to the solar gains, however that risks is minimized by reducing the window size and making the windows on the north side horizontal instead of vertical. This in the end also gives the building a more evenly distributed daylight.

Personal Statements ANTONIO

This term 2 project was great to assimilate the lessons from outdoor spaces I had arrived to in the research project from term 1. In addition, it was also good to learn from my colleagues’ strategies about indoor comfort in housing.

MARIANA

Half of the team studied outdoors in the previous term and the other half studied indoors spaces, therefore we felt strongly about merging the two fields of study into one project. I aimed to create a semi outdoor space, by designing a structure that could respond to indoor conditions as well as outdoors.

Starting a project from scratch is always a challenge. In this particular case, we planned a strategy to approach the site as a group, starting The café was designed to provide service to the spaces that surround it, with several field visits to understand the atmosphere of the area. We such as the pool and the outdoor gyms. performed fieldwork using the instruments that were introduced in The site was a closed location, so we couldn’t go inside to perform the previous term, we did research about the history of the site, we spot measurements; therefore we had to rely on the weather data from observed and interviewed people, and all of this helped us to determine Meteonorm’s weather station (London City Airport). The process started the research questions that should be addressed by this project. by taking the lessons learned from the Term 1 Project and introduce and As mentioned above, I had already some knowledge about outdoor taking them into consideration. spaces and pavilions that I had acquired in phase 1. Here, I concentrated Several designs for the structure were made and scenarios were my efforts on the outdoor comfort of the wooden promenade design, simulated in order to arrive at a design that falls within the topic of particularly of the Outdoor Gym. We decided to make an Outdoor Gym Sustainable Environmental Design. due to the fact that students usually cannot afford gym fees. We though the Outdoor Gym would offer people a great alternative to practice In this project I had the opportunity to design a structure and understand exercise. the importance of the tools that we have been taught at this program. The research questions addressed by the Outdoor Gym were the As a result of this project I have learned a lot about how sustainable following: (a) how to achieve outdoor comfort during the practice of sport design actually works and several types of environmental strategies to during the different seasons of the year?; (b) how adaptive strategies provide a good and comfortable space for its occupants. can play during all year? To answer these questions we employed two different tools, Ecotec and CBE. The result of my work was the design of this gym, which interacts with users and requires them to adapt. Finally, and regarding the outcome of my work, I would like to highlight the importance of several enthusiastic and inspiring lectures provided during this term.

108

ARTURO REYES During this short period of time that is Term 2 of the AA MSc SED programme, I gained a great amount of knowledge about the specific subjects being taught, with all the amazing lectures we had with exceptional people working and leading the field of Sustainable Environmental Design and also about the complexities of team design, understanding the importance of predesign analysis and research as the base of any successful project in academia and in life outside of it. Recognising the invaluable help and assistance from all of our tutors. One of the most important challenges of this term for me was the application of last terms gained knowledge to a design proposed from scratch and one improvement I would propose is the earlier teaching of alternative software like Open Studio, which will be undoubtedly beneficial for our future work but was introduce late in the term for us to be able to use it in the term 2 project given the fact that TAS can only be used by one person at a time and reduces the chance for the others to learn the software. Without wanting to sound repetitive I would like to personally thank Mariam Kapsali and Herman Calleja for their after hours assistance during the tem. They helped me understand somo key factor of the SED methodology.

MICHELLE KUEI Term 2 project started with us combining our previous experiences from Term 1, two of our teammates were studying outdoor spaces in Term 1, and the other two studied more on residential spaces. As a result we decided to design a housing project with large outdoor area around it; the size of the area we decided to take on was ambitiously large.

I focused more on the housing project, and since the project is located in London, my teammate and I wanted to give the housing units as much solar access as possible. However once the project is put into TAS simulation we quickly found out that even though the housing units have their majority of windows facing South, the units still suffer from under heating in the winter once the sun sets. Heating is assigned to winter occupied times. Since the building is facing south, it gives us a chance to compensate the energy consumption of heating by applying PV panels. However we do had to constrains ourselves in building forms in order to give the PV panels the maximum access to solar. The communal living room also is under heated in winter nights, although it could be noted that those are the times the living rooms are not occupied and without any internal gains. Since our objective was to give more solar access, we will have much solar gains during the summerâ&#x20AC;&#x201D;ventilation and louvers do effective jobs in naturally cooling the spaces in summer when there is a temperature peak. Given more time, our next step is to look into interior materials and try to find a combination that will help retain more heat for the winter.

On a final and more personal note, this term is the first time I begin to rely on TAS substantially, the program is complicated and requires a lot of knowledge on SED to model the project properly. Nonetheless I am happy to say that in the end I set up a fairly complex TAS model and through the long, at times painful modeling process Iâ&#x20AC;&#x2122;ve gain a clearer knowledge on how things work with each other in a space.

You can earn money from your panels in three ways: 1. Income from the generation tariff: you will be paid for every unit of electricity that your panels generate as part of the Feed-in Tariff. 2. Money saved on your electricity bill: a proportion of the electricity generated by your panels will be used directly in your home, reducing the amount of electricity that you need to buy. 3. Income earned from export tariff: some of the electricity generated by your panels may not be used directly in your home. You will be paid for every unit of electricity that you are able to export to the grid as part of the Feed-in Tariff.
