Special thanks to the University of Westminster for providing the required tools that were used to take measurements.

INTRODUCTION Regentâ&#x20AC;&#x2122;s place is a very unique site, occupying a 13 acre area in the London borough of Camden, just north of the Euston road, to the east of regent's Park and west of Euston station. The life style in the plaza summarizes a typical fast eventful life of a major city such as London. Observations were essential on weekdays and weekends to understand the urban layer, occupants behaviour, other spot parameters and their impact on our list of climatic investigations. The team conducting the study contains of three members. The work has been steered on few main stages that have been planned out on a mind map to manage the time frame given and fitful the requirements shown in figure -5-. According to the life style of the plaza the findings were related much to the occupants behaviour, the way they deal with regents place environmentally and socially. With that we concluded that managing the environmental aspects of the space would supply the design lots of benefits that are useful for both the occupants and the environment. This project has taught us that there is a strong association between social and environmental demands, it educated us to come up with solutions to deal with the environmental issues that are both ecofriendly and architecturally aesthetic.

PROPOSED INTERVENTIONS Noorihan Deraz The environmental and energy modelling module has enhanced my abilities in designing an environmentally friendly space that also contributes in the social aspect and lifestyle of the occupants today and in the future. Making the designs both suitable and architecturally aesthetic.

Lina Safarini The environmental energy modelling course is

challenging in a way that incorporate art and design into a new environmental awareness, responsive and efficient architecture. As it focuses on the theory and practice of developing low carbon and sustainable building designs. The regents place project was a great exercise to combine all the environmental thinking into an applicable design in real life.

Bilal Shibib After last terms analysis of a building and its

performance, this term we were able to design an environmental friendly facility. My group and I have chosen Regent's Place as a location because we recognized a lot of potential in it. I enjoyed working on the site, especially because it was on top of a building, making it challenging and exciting. I have learned strategies such as how the geometry of a building can influence the environment and how it can enhance a buildings performance as well as looking good. With the knowledge I have gained during the few months, I am looking forward to use to work on my upcoming dissertation to help create a better future.

INITIAL STEP For the sources of data we were able to speak to a total of 13 people,10 of them work at the is Santander head office bank, 3 of them from the reception desk and the rest are employees and 3 security grads of the plaza that have been working there for at least 5 years. The parameters considered in the study have been concluded from surveys and observations such as thermal comfort, daylight and visual comfort and their value to the employees of regents place. Spot measurements of the site have been also conducted using the following tools shown in the figures (1-4): 1. 3in1 Compact Vane Anemometer 2. Lux Meter 3. Infrared Thermometer 4. Sound meter

LOCATION London, England’s capital, set on the River Thames, is a 21st-century city with history stretching back to Roman times. At its centre stand the imposing Houses of Parliament, the iconic ‘Big Ben’ clock tower and Westminster Abbey, site of British monarch coronations. Population in London is approximately 8.539 million (2014) The selected site is located in north-west of London. Regents place sets in the London borough of Camden, just north of the Euston road, to the east of regent's Park and west of Euston station.

Figure -10- Regent’s Place 1970

Figure -9- Regent’s Place 1950

Figure -11- Regent’s Place 2016

Development of the site throughout the years is severe. In 1890 Regents Park was split into two lands named Park square and crescent gardens. Regents place block was a residential area. In 1950 the block was converted into a mix of business offices, houses, a school and a church. In 1970 Regents Park was still split into two sides and the block contained business and retail buildings. In the early 1990s, Regents place was a battleground. There was gang fighting and other disturbing events Houses were derelict. Before the master plan, Regent’s Place was a disconnected commercial enclave that contained Thames TV studios, after it has been demolished in 1996 after it closed down in 1993 because they lost their franchise. Through the Partnership happening in the early 1990’s, developers and investors joined with the council, local ward councillors, the police, University College London, the NHS, community organisations and other local stakeholders with one common aim, to make the area a better place to live and work. regents place development was between 1997 and 2013. In year 2000 2-3 Triton Square was built, a 7 storey building which is Santander UK Head Office.

LONDON WEATHER An A1B scenario of London and Camden weather have been prepared to understand the change as well as developing a design that is suitable for the future and all seasons. London weather predictions in 2050 expect higher participation levels especially during between July and December. A slight increase in the sunshine duration occurs in 2050 during summer specifically between June and September. Meanwhile the temperature difference is stable and doesn’t change drastically between the present case and 2050.

Site is located on a main road Euston road, making the traffic very slow at some parts of the week specially traffic directed towards Baker street to the west. The graphics demonstrate the traffic pattern during the weekday and on the weekends on three different times of the day. During the week, Euston road at 2pm is busy as it is a rush hour at between 5:00 pm and 6:00 pm. On the other hand during the weekend there are no office hours results in smoother traffic pattern or faster. Pedestrian walking pattern. Busy during the week specially during the day. The plaza shops operating result in continuous movement pattern on the other hand on the weekends since the office building do not operate it results in less movement around the and within the site.

EUSTON ROAD TRAFFIC IMPACT ON FEW CLIMATIC PARAMETERS The impact of Traffic and movement patterns on pollution, noise levels and humidity directly in the site as it is located on a main road Euston road. The impact of having a main tube station and 5 different bus stops around the plaza, also the amount of pedestrian movement in the plaza especially during the week resulted in high humidity rate especially during the weekdays. The air Pollution changes between a weekday (Moderate) and a weekend (Low) depending on traffic density. According to the Camden time histories regarding the noise levels that has high noise pollution in London

SOUND REDUCTION CALCULATIONS

According to the sound study conducted on the previous page figure -44- a sound study prepared to estimate the sound parameters on top of the roof for our site. The sound reduction formula used is as following: Each additional 1m height = increase 1.5 db in noise reduction. 33mx1.5= 49.5m Street noise level – proposal noise level height = 93 – 46.5 = 43.5 db Wall barrier reduces 5 db 43.5 db – 5 db = 38.5 db

PEDESTRIAN MOVEMENT IN RELATION TO HUMIDITY Due to the high human and vehicle traffic during the weekday. High humidity rates are shown in the plaza and the points closer to Euston road. Especially in the centre were many shops are operating, in addition to the northern side of the building were many facilities are happening such as some outdoor activities and food markets. On the weekend relative humidity has lower rates especially afternoon.

SHADOW ANALYSIS A sun path study in relation to shadow analysis showing the impact on the site and the plaza for further thermal and visual comfort studies. The result of this study is that the plaza is exposed to solar radiation depending on the season and the hour of the day. Meaning, the built form does not obstruct much of the solar radiation except certain hours specifically after 2:00 PM in the summer and the winter. The total radiation for a meter square is approx.. 685 kwh/m2. Figure -77- The Shadow analysis 10 am, July

According to observations, Employees are usually in a rush even during break times their routines were identified as very fast pace especially in the outdoor public plaza. Therefore, enhancing the social life in the plaza is essential. Users behavior vary according to seasons. In summer, many activities take place in the public plaza, gathering the public and the employees of the place during break times and after work. Some food markets and other events are held in the plaza including an open air cinema and mini golf events. In the winter, the plaza would be mainly busy with employees. Due to the weather conditions causing less outdoor activities.

DESIGN DEVELOPMENT The sun angles during seasons were considered as the building shape inclination is 6oâ&#x2014;Ś so maximise the amount of direct solar radiation in the winter but limit the access during summer time. The south faĂ§ade angles were more than 60 degrees in order to receive a higher amount of day light throughout the year. The external shape remained the same in order to create shading during summer time.

OUTDOOR EXPERIENCE - ROOF GARDEN

Figure -104 - Global solar radiation in Summer

Figure -101 – view from mesh of social library to roof garden

According to the roof surfaces analysis the roof garden was designed creating areas that control the high exposure of south solar radiation. To enhance being in that area a mesh structure was added to be a semi outdoor/indoor space for the library, Greenery demonstrated in trees in a pavilion taking the occupants few steps lower to be shaded by a specific choice of trees protecting from Euston road pollution specially during the week. These areas along with circulation between them are designed to enhance the social connection between employees and visitors if any. To improve the protection from the high air velocity a glass barrier with an inclination is added to allow a certain amount of breeze and fresh air required. Certain elements that are added for environmental proposes are boosted in a way that they can be socially used. Such as wooden/glass benches that act as lighting tunnels and ventilation openings from the sides for the space in the lower level. Surface studied during peak hours: Lunch breaks 12-2pm After office hours 17:00PM – 19:00PM Trees added to reduce Euston pollution and improve air quality:

THE HAMMOCK HALL – Daylight studies

AUTHOR: NOORIHAN DERAZ The Hammock hall is designed to be an escape from the hectic employees life everyday. It is located on the main level of the building with a direct connection to the roof garden. The idea of the hammock hall is a getaway where busy employees can enjoy sometime away from the busy office life to a green calm very nature friendly atmosphere as its objectives are to enhance the social life and enhance people’s connection with nature.

Figure – 108- Hammock hall daylight and ventilation summary

One of its main features is the dynamic ceiling that is adjustable according to seasonal responses. In the summer time, it can be opened to increase the amount of solar radiation, increase the level of illuminance and to improve the ventilation rate. The mesh that is attached to the ceiling functions as a support of the hammocks and controls the amount of solar radiation accessing the hall when the roof is opened in summer. Level 1

Peak hours: Lunch break: 12-14 After office hours: 17-19 The hammock hall was simulated in PDA in order to study its performance during different seasons. According to the number of occupants, zone area and occupancy hours, simulations have proved a positive percentage of comfort in comparison to discomfort. In summertime, the operative temperature is slightly above the comfort band, between the lunch break 12 pm to 2 pm that can be solved with increasing the ventilation rate. And, after work hours 5 pm to 7 pm. In winter, the indoor operative temperature is slightly under the comfort band, between lunch break yet tolerable.

NATURAL VENTILATION IN THE HAMMOCK HALL

AUTHOR: NOORIHAN DERAZ Cross ventilation strategy was implemented in the design proposal. Due to the propsal height +33, High wind driven is expected throughout the seasons. The dynamic roof can be opened during the summer time and mid season as it will create a semi outdoor experience that will improve the cross ventilation flow and create indoor temperature balance. Optivent results shows the amount of openings in the building design can almost achieve the required amount of cooling but achieved the required amount of fresh air. The amount of fresh air required per person is considered.

CASE 1 ZONE PERFORMANCE / HAMMOCK HALL – Basic number of windows Basic number of windows refers to having only one or two small openings in the facades to determine the amount of environmental requirements needed. After running this test it is concluded that the ventilation rate according to the aperture flow in and out would be very low specially in the warm season. Also, the temperature is severely affected by the amount of solar radiation getting. For instance choosing the cold season the temperature goes down to almost 6°C making it too cold. While in the summer temperature goes up to almost 28°C making it a bit out of the comfort band. So the next step would be adding the amount of windows required to reach comfort.

In this case windows needed and fixed double glazed facades have been added but without adding any shadings or blinds. The conclusion as expected is too hot in the summer and too cold in the winter making it out of the comfort zone for the occupants so in that case dynamic shadings are added to be fixed depending on the season. Considering that the hammock hall is a double height space of 6m with an inclination to the back wall goes down to about 4m.

CASE 3 ZONE PERFORMANCE / THE HAMMOCK HALL – No internal gains After adding the shading and the windows fulfilling the requirements the simulation is a space that has no internal gains. That includes human and equipment gain. In this simulation it is concluded that the humidity percentage is low except in the winter expecting that it becomes airless in the space. But the temperature is still controlled in the summer because of the dynamic louvers controlling the amount of solar gains accessing the space but too cold in both midseason and winter. For that in the next simulation a full study is done that includes internal gains calculated.

THE SOCIAL LIBRARY

AUTHOR: LINA SAFARINI The social library is located on the ground floor of the building, which is +38m above the street level on top of the roof of the bank building of Regent's Place. The Concept behind the social library is to have an outdoor and indoor space integrated into one social space, to endorse the connection with the outdoor social living, that will result in enhancing the social life and peoples connection with nature.

THE SOCIAL LIBRARY

AUTHOR: LINA SAFARINI

An architectural mesh is added to enrich the social relationship with shade and shadow to be able to use the outdoor space in the summer avoiding the high exposure to the south solar radiation. The main feature in the library design is the outdoor mesh that is located in front of its entrance. The dynamic feature of its vertical movement helps adjusting it during the seasons. This feature is mainly designed to create a connection between the library and the roof garden. The mesh can be lifted up so it creates a canopy during summer time. The mesh allows a certain amount of solar radiation to access. Therefore, it creates a dynamic lighting pattern under the canopy as well as a floor pattern and an atmosphere. The air movement creates a naturally ventilated space through the material used (wood). This component is designed to function during the summer time and warm days thru the mid-season. While in the winter time it will be closed down creating a semi outdoor space and a semi outdoor library extension.

CASE 2 ZONE PERFORMANCE / SOCIAL LIBRARY – No shading In this case openings needed and fixed double glazed facades have been added but without adding any shadings or blinds, as it shows that the indoor temperature during the summer season is extremely out of the comfort zone as it reaches 41°C due to high solar gains accessing the room. In comparison to winter season, the indoor temperature faces a severe decrease in temperature which requires additional heating devices. In that case dynamic shadings are added to be fixed depending on the season allowing flexibility in controlling the amount of direct solar radiation accessing the room.

After adding the external shadings and the openings fulfilling the requirements the simulation has been tested as the a space that has no internal gains. That includes human and equipment gains. In this case the results show during the summer time the indoor temperature is within the comfort zone, it starts decreasing towards the winter season where the temperature reaches 7°C indoors. By adding internals gains, the temperature will be increased and enhanced towards the comfort level. Higher ventilation rate is required during the summer time in order to balance the indoor temperature. Peak occupancy hours are highlighted in grey boxes.

THE QUIET ROOM – Daylight studies

AUTHOR: BILAL SHIBIB

It has been proven that power napping improves the concentration by 34%.The pod's promote blood circulation by elevating the feet, relaxing the lower back, and slightly bending the knees. The quiet zone is located on the first floor which is +41m on top of the existing site. After doing few interviews with few employees in the plaza during the lunch break many suggested a place where they can take a short nap during lunch hours. Therefore, this space is designed as a getaway where busy employees can enjoy some time away from hectic lives to a completely quiet semi dark zone. The main elements in this zone are sleeping pods. Space elements: I 1. Double façade with some greenery and dark glass allowing minimal daylight through the S façade 2. A narrow window along the north façade for warm daylight and

According to the number of occupants, zone area and occupancy hours, simulations have proved a positive percentage of comfort in comparison to discomfort. In summertime, the PDA results show that the operative temperature during the peak hours from 12 pm to 2 pm and from 5 pm to 7 pm are within the comfort band.

THE QUIET ROOM

AUTHOR: BILAL SHIBIB

The pods help boost productivity by providing 20-minute naps. Its spherical dome enclosure provides semi-privacy; a privacy visor provides additional seclusion. Controlled at the armrest, a built-in timer is set to a pre-programmed 20-minute nap, but can be set to any preferred nap time. The pod gently wakes nappers with slowly brightening light and vibration. The armrest remote also controls the heated mattress of the sleeping pod to provide the optimal thermal comfort. The double façade with some greenery functions as a cross ventilation strategy, where the wind enters from the south double façade and exits through the north opening. The room is rather kept dark to satisfy the relaxing atmosphere for the nappers. The north opening supports cross ventilation technique proposed.

Basic number of windows refers to having only one or two small openings in the facades to determine the amount of environmental requirements needed. During the summer months, the indoor temperature is slightly above the thermal comfort with an average humidity of 20%. As the weather gets cooler, the temperature goes below thermal comfort during mid-season as well as winter. Peak occupancy hours are highlighted in grey boxes.

After adding the shading and the windows achieving the requirements, the simulation is a space that has no internal gains. That includes human and equipment gain. In this simulation it is concluded that the humidity percentage is low except in the winter expecting that it becomes airless in the space. The temperature is slightly above the comfort zone but still cold in winter. For that in the next simulation a full study is done that includes internal gains calculated.

CASE 4 ZONE PERFORMANCE / THE QUIET ZONE – Improved results The improved results are obtained after applying the suggested environmental techniques and theories. The double façade in addition to the greenery that was applied on the inner side creates diffused solar radiation, that keeps the indoor temperature within the comfort zone during hot seasons on peak hours as well as throughout the day. As the weather gets cooler, the indoor temperature decreases and drops below the thermal comfort zone. This is done to achieve the required atmosphere in the quiet room. The idea is to create a cool area with sleeping pods that can be heated up as the individual napper requires. Peak occupancy hours are highlighted in grey boxes.

GAMEROOM – Daylight studies The game room and lounge take place on the -1 level and that is +33m from the ground level on top of the bank. The space is designed to serve the entertainment side of regent’s place. As it contains of few games, a TV corner and a snack bar. The game room is located in a very critical part of the proposed design as it is considered the lowest level comparing to the rest of the spaces. For that solar control techniques were processed on different stages to fitful the required illuminance and daylight.

GAMEROOM Cross ventilation strategy was implemented in the game room in order to enhance the air flow movement. Therefore, will improve not only the air quality but also cool down the space during the summer season. The shape of the openings in the ceiling are designed to have multi-purpose use. the three openings function as a skylight for the game room and on the roof the shape can be used by occupants as benches. High wind driven is expected due to the height of the building.

The simulations show that the indoor temperature during the summer season is within the comfort zone. Especially during the peak time of occupancy during the day.

Peak occupancy hours are highlighted in grey boxes.

CASE 4 ZONE PERFORMANCE / THE GAME ROOOM – Improved results This is the result obtained after applying the suggested environmental techniques and theories.

SUMMER

By applying shading devices that can be adjusted during seasons to limit the access of direct solar radiation, can improve in the quality of the thermal indoor space.

After simulations the graphs show positive results especially during the summer time. During the cold seasons additional it is expected that internal latent gains will be higher and that will help increasing the indoor temperature.

BUILDING PERFORMANCE – Ventilation

Figure – 146- ventilation performance Figure – 147- ventilation performance

Cross ventilation strategy was implemented in the design proposal. According to the rule of thumb, buildings with a height of less than 100 meters, would have air velocity across their roofs. Therefore, the assumption of natural ventilation, is wind driven. As the graphs demonstrate, the results of ventilation process during the summertime is achieved in comparison to required amount for cooling and fresh air. On the other hand, where there are less amount of openings, such as the closed ceiling of the hammock room, fresh air is still provided and the amount of cooling can be controlled according to the users desire. The geometry of the design along with the free standing glass that acts as a windbreaker which decreases the air velocity in the roof garden and creates a pleasant and comfortable outdoor experience for the users.

CONCLUSION

Figure – 151 – Model

The insights of the work obtained on this project can be summarized in the following: 1. Building on top of roofs requires managing the countless amount of solar radiation and wind received. 2. The getaway centre is designed upon the environmental aspects of the site such as solar and wind studies 3. There is a strong relationship between the social and the environmental demands. 4. Utilizing environmental factors and transforming them into environmental and architectural design strategies. 5. Taking the surrounding’s building typology into consideration in terms of sky view and over shadowing. 6. Choice of building fabric is upon sites condition, environmental performance and application time management. 7. Enhancing the relationship between the outdoor and the indoor spaces by transparent facades and seasonal architectural elements. 8. Enhancing the greenery indoors has improved the indoor environment and experience. 9. Multi-use elements that are designed in a way that serves multiple functions at a time. 10. Dynamic louvers that manage the solar access and thermal control. 11. The energy demand required over all is 148 KW/m²/year, the heating is only 39.1 KW/m²/year which is dealt with via renewable energy sources suggested previously. 12. In this proposal the main consideration was the design before the sources of the renewable energy and after running the studies and the simulations the design has shown success most of the year and it is gathered that using photovoltaic for a specific time of the year has been minimized as much as possible and only used when needed.
