This course dwells upon the dynamic, energetic phenomena on Earth, and their impacts on how humans conceive and construct buildings and cities. Solar energy drives terrestrial, geologic, hydrologic, ecologic, and, increasingly erratic climatic systems. Beginning with introductions to basic phenomena such as daylighting, thermal comfort, and resilience to extreme weather, students will learn how such phenomena are intimately tied to architectural construction at multiple physical and temporal scales. In the first half of the course, a research project on world cities will allow students the opportunity to develop representations of non-visible phenomena, as well as research prototypical methods of human climate adaptation specific to their locale. In the second half of the course, students will develop a diagrammatic architectural form for post-environmental disaster multi-family housing in response to various energy systems, making use of various digital tools, notibly DIVA for Rhino. Throughout the course emphasis will be placed on â&#x20AC;&#x2DC;passive,â&#x20AC;&#x2122; or non-electro/mechanical methods for adapting buildings and cities to local (and increasingly variable / warming) climatic conditions. By the end of this course students should be familiar with a series of workflow methods for researching, analyzing, and optimizing architectural and urban form through the lens of energetic systems, and understand the underlying concepts so as to make informed design decisions using various data sources.

COBAR

SYDNEY

Average yearly rainfall in Cobar is 16” (compared to 43” for Boston). However, rainfall can be erratic as seen in the graph below. Winds are generally light throughout the year, averaging below 10mph. Solar radiation in Cobar is the most exergetic source of natural energy and should be the main influence for architecture. For comparison, Cobar receives almost twice as much solar radiation as Boston. With average summer highs near 95°F and average winter lows near 40°F, available solar radiation needs to be used for cooling in the summer and heating in the winter.

Cobar, Australia Khalil Farhat Renewable energy sources account for 13% of Australiaâ&#x20AC;&#x2122;s electricity generation. Even with high solar radiation levels, only 1.5% of electricity in Australia comes from solar Hydro power: 7.3% Wind power: 2.9% Solar PV: 1.5% Bioenergy: 1.3

This house in Cobar uses minimal sustainable strategies to cope with the local climate. It is not a good example of climate responsive architecture. The substantial paved area retains solar energy and creates a local heat island. The paving reduces rain water infiltration on the site and causes runoff

KUALA LAMPUR

Situated to the west of the Titiwangsa mountains and to the east of the Sumatra Island, Kuala Lumpur has a Köppen climate classification of Af which is a tropical rainforest climate. This climate classification entails warm and sunny days, along with copious rainfall, especially from October to March during the northeast monsoon season. Temperatures tend to remain constant. Maximums teeter around 88°F and 91 °F and have never exceeded 102.7 °F, while minimums teeter around 71.6°F and 74.3 °F and have never fallen below 57.9 °F. Kuala Lumpur typically receives minimum 100 in of rain annually; June and July are moderately arid, but even then rainfall typically exceeds 5.0 in per month. Flooding is a frequent incidence in Kuala Lumpur whenever there is a heavy downpour, particularly in the city center and downstream areas.

Accra DESIGN STRATEGIES 01 response to sun Large overhangs to reduce incident sun on the facade. This strategy also reduces incident radiation on the facade hereby reducing heat gain into the living spaces. Houses are equiped with manually controllable louvers to block out the sun.

02 response to wind Capitalising on natural ventilation, prevailant winds are channeled through the building via its orientation. Floors and roofs are raised to allow wind to flow. Strategic placement of the openings encourages cross ventilation.

SCheme mASSING EXPERIMENTATION

SCheme 01 The idea here is to design a project (which formally evokes a slum) with units stacked in such a way that the upper levels cast shadow on lower levels. That allow to create the a cool ground floor space where people can gather.

03 response to rain Floors are raised, keeping living spaces dry to adress possible flooding situations during the rain season from April to June. Rain water is collected from the roof and stored in tanks to provide non potable water. Some of the water may be used to irrigate greening on the facades.

design matrix / roof inclinations The goal in this study is to show the yearly solar radiation on differently oriented roofs. The worst surfaces in this region are those facing east at about 10 degrees (red), the best ones are at an angle of 60 degrees.

e 02 In this version we have two rows of units oriented N/S we can see that overhangs protect the south facade from direct sun light.

I rotated the units so they face the prevaling winds coming from SW. this approach allows natural cross ventilation in the units which is a key element in an hot-humid climate.

Prevailing Winds SW

To provide sufficient ventilation, bamboo vents have been designed. Built from smaller bamboo canes, they provide small openings to let air in the building, while keeping sunlight out. These elements can also be used to provide additional shading on the porch surrounding the building

section To prevent flooding, the floor was raised. This allows fresh air to cool down floors and also protects the inhabitants from pests, such as scorpions and snakes.

Typical plan

synthesis 13

South West angle

South Est angle

An outer and independant casing detached from walls acts as a protective box structure and creates voids that allow air to flow through the building. The large overhangs as well as the bamboo brise soleil protect the west and south elevations. This system provide a filter to the entrance of solar radiation without affecting natural ventilation. As we can see above all the walls receive around 0 to 500kw/m2 of solar radiation.

On the Western elevation most of the wall is protected by the sun. This can be enhanced if user use the brise soleil to grow some vegetation.

Bisbee is an old mining town in Southern Arizona, near the border with Mexico. A large billboard boasts that Bisbee has the best year-round climate in the world! Bisbee is relatively dry, with an average annual rainfall of 18.63 inches. Most of the rain occurs during monsoon season from July to September. Itâ&#x20AC;&#x2122;s high elevation (5538 ft) makes it cooler than nearby lowland areas. Bisbee was founded as a copper, silver, and gold mining town in 1880. The city flourished until 1950 when mining operations were stopped. The city was doomed to become a ghost-town! Thankfully, tourism of the mine and the relocation of Artists to the area relivened Bisbee to the quaint city it is today. Two main avenues fork through Bisbee, splitting it Southwest/Northeast along the valley of the Mule Mountains. Cloud Cover

Travelling through Morocco in 2012, I stayed with a nomadic Berber family. They housed and fed me in their clay and hay home. The families live in small oasis villages in the middle of the vast and barren Sahara Desert. The young men used to travel on camels through the desert for trade purposes, now they take travellers and tourists into the desert. During desert journeys, they stay in black tents around a fire. The fabric of the tents allows air to pass through in the heat and swells to protect from rain in its rare occurrence. The same fabric is used in the ceiling pictured.

Seattle is bound by the Olympic Mountains to the west and the Cascade Range to the east. Seattle’s proximity to the ocean makes for a moderate climate where temperatures do not fluctuate greatly. The summertime temperature trends support the sea breeze theory, with average highs each year in the mid-70s. Typically the summer months have lower amounts of rain, which could be due to the rain shadow effect from the Cascade Range and Olympic Mountains.

The Solar Envelope This is a model of the cubic footage that we can design within in order to not cast shadows on neighboring buildings. This is a good starting point for general building massing.

Looking at Louvers A simple test to see what 1 foot louvers would do to the quality of space.

Interior Light Study I wanted to see if light would be able to penetrate such a large square space, so I built a scale model and did some daylight testing. This was a great experience because it allowed me to get an idea of how the space would feel in different lighting conditions. I was also able to try out a louver system for the windows, though I found that working in section was a bit easier. Here are a few of the process photos and results. I found that this shape works because light is able to enter fairly deep into the interior. The most light enters the space during the winter when the sun is low. There are even points of the year and times of day when light hits the back wall.

9412

Rotational Study I hypothesized that rotating a structure on the site so that one wall was facing directly south would mean higher levels of solar radiation on that wall. However this rotational analysis made me realize that the difference in solar radiation is so minor between Southwest, South, and Southeast that it is best to use the square footage of the site efficiently by placing the building square to the perimeter to minimize

SEATTLE DESIGN PROCESS Massing Studies The images represent a study of four different massing options. This was an experimental process and required a lot of trial and error. The last model is the most notable option because it was created by cramming the program into the solar envelope as efficiently as possible. While each model has some positive attributes, I decided to move forward with the last one because the soalr radiation was most evenly distributed over the building and it doesn’t cast shadows on its neighbors. However there are some areas that receive no light and have no windows, so I set out to resolve the iteration into a more comprehensive solution.

Option 1: The ‘L’ Shape This shape works alright, but there is some space in the corner of the L that doesn’t get any southern exposure or crossventilation.

Option 2: Two Towers This configuration allows for maximum sun exposure but is not very efficient because it is two seperate buildings that cannot share vertical circulation.

Option 2: Leaning Stack The interio of these buildings would be fairly pleasant, but this massing creates an awkward overhang on the North side of the site, and the space underneat would receive little solar radiation.

Option 4: Solar Envelope Fit This massing was determined by squeezing the program into the solar envelope that was created at the start of my research. The radiation is more evenly distributed in this option.

9614

Pros and Cons Option 4 seems like the best option since the solar radiation is most evenly distributed. In addition, it fits within the solar envelope it will not cast any shadows on our neighbors. However, a closer look reveals that a few of the units would not receive any southern exposure or get a cross breeze in line with the prevailing winds.

Solution In order to make sure that each unit gets plenty of solar radiation I moved all units to the Southwest edge of the site and organized them all in a row. This way each unit gets a full wall of southern exposure and it allows for a cross breeze through each apartment. In this version no apartment is blocking another unit.

Rue des Grisons Quebec City, Quebec, Canada Design Objectives 1. To maximize the winter solar access of the site and new structure. 2. Prevent snow accumulation on neighboring buildings points of access. 3. Minimize the energy expended to heat and cool the building.

Program requirements 1. 10-20 1000 sf residential units. (approx. 10,000 to 20,000 sf total) 2. An exterior opportunity for residents of the area to experience the view of the major landmarks and the river in the form of a roof deck or park.

Design Process 1. Diva iteration 1: Find Form Through an iterative process, starting with a box filling the space, I used DIVA to test several forms for the best type of form that would maximize solar access in the small site. Massings 2 and 3 are examples of two different forms that are known to maximize solar access. Massing 2 is a tiered structures and Massing 3 uses the sun path at the winter solstice to create the form (allowing approx. 2 hours of direct sunlight on the neighboring buildings). Massing 4 uses the knowledge gained from the first 3 iterations to inform a new type of form, a tiered, pronged structure.

2. Diva Iteration 2: Test Rotation The second set of iterations use a two pronged structure. Going from 3 to 2 prongs accounts for objective #3 by decreasing the overall exterior surface area of the structure. Massings 5 - 7 test several different angles of rotation. From these tests, I learned that both the angle of the prong and the distance between the prongs has a large impact on solar access. Increasing the angle of the parallel prongs decreased the distance, creating a cavern that did not allow for much solar access and could be an opportunity for snow and debris accumulation due to wind patterns to negatively impact the site.

3. Diva Iteration 3: Maximize for solar access and The final set of tests rotated the prongs independently, allowing for more space between the prongs. The final iteration, number 10, proved to allow for the maximum solar access to each prong and the neighboring building. In addition, it allows for greater access to any snow accumulation and more ventilation throughout the site.

3. Using precedent studies and known technology to improve climate responsiveness Finally, using the precedent studies, I implemented further techniques that would increase the buildings effectiveness and livability. This included glazing, to offer views of the city and river, and a double wall glazing system that would allow for increased heating and cooling efficiency . Also, I identified areas for the addition of photovoltaic panels and rainwater collection.

Windows are placed on the three sides with both, the most solar access (E, SE, SW) and views of the city and river.

Design Objectives 1. To maximize the winter solar access of the site and new structure. This design maximizes solar access throughout the year to the structure and the neighboring buildings.

2. Prevent snow accumulation on neighboring buildings points of access. By opening the slot between the two prongs, I have increased the ability to manage precipitation and wind.

3. Minimize the energy expended to heat and cool the building. This design minimizes the overall exterior surface area, while maximizing the solar access to all units. In addition, the double wall glazing system will increase the buildings ability to cool in summer and heat in the winter with the aid of solar gain.

Source: Rhino 3D

Final Design Solution The North sides of the building would be mat-white, to reflect as much daylight into the interior spaces of the adjacent units and buildings as possible.

Annika B. Nilsson Ripps

Program requirements 1. 10-20 1000 sf residential units. (approx. 10,000 to 20,000 sf total) 1st Floor 2 units (each 1175 SF) 2nd Floor 2 units (each 1000 SF) 3rd Floor 2 units (each 900 SF) 4th Floor 2 units (each 775 SF) 5th Floor 2 units (each 1800 SF) A total of 11,662 SF of interior space.

2. An exterior opportunity for residents of the area to experience the view of the major landmarks and the river in the form of a roof deck or park. The roof deck is a total of 3,767 SF. This would allow for 3,000 SF of roof deck toward the north east edge and 700+ SF toward the south-west edge for photovoltaic panels and rainwater collection to further the energy efficiency of the building.

Summer As the prevailing winds run northeast/southwest, opening the slot between the prongs increases ventilation to all units.

Winter

The glazed walls are double-wall systems. This minimizes heat loss in the winter and allows ventilation to help cool the interior during the summer.

The house at 1630 Linkebeek uses strategically positioned skylights in conjunction with the central stairwell to daylight spaces that would otherwise rely on artiďŹ cial lighting. In order for the stairwell to act as a lightwell, porous materials and white ďŹ nishes were used.

222 Avenue Van Volxem is an interior retrofit project by Vanden Eeckhoud-Creyf Architects. Notably, the floor plates do not extend to the wall along significant portions of their perimeters. This allows air to flow freely throughout the interior. Being a row house typical of urban areas of Brussels, it is tall and thin. The two party walls minimize thermal losses through the envelope.

The row house is a ubiquitous typology in Brussels. The tall, narrow shape of the interior space makes it an ideal candidate to utilize the stack effect for passive ventilation. To capitalize on this opportunity, sizable sections of the floor plates on the second and third floors are set back from the perimeter, leaving generous openings for air flow.

The form of the house works with the prevailing winds in the area to assist ventilation, especially in warm weather. Being on the lee side of a row of similar structures creates a low pressure region that enhances the stack eﬀect when the roof window is open, drawing fresh air into the whole house.

THE MAJORITY OF THE WIND COMES FROMS THE SOUTH-EAST. THIS IS MOST LIKELY CAUSED FROM THE COLDER OCEAN AIR COLLIDING WITH THE WARMER AIR OVER LAND CAUSING CHANGES IN PRESSURE WHICH RESULTS IN A BREEZE.

Because of Osloâ&#x20AC;&#x2122;s Northern location, it receives more than 18 hours of sun during the mid-summer. During the winter, day light can be as short as 6 hours.

PROGRAM MY DESIGN WILL NEED TO CAPTURE AS MUCH SOLAR GAIN AS POSSIBLE BY POSITIONING MY WINDOWS IN PLACES THAT HAVE HIGH SOLAR RADIATION. THICK INSULATED WALLS WILL BE IN AREAS THAT RECEIVE LITTLE TO NO SOLAR RADTION AND HEAVY WINDS. TO GET LIGHT INTO THE DARK, COLDER LOCATIONS I WILL USE BRIGHT MATERIALS IN THE LIT AREA THAT REFLECT ONTO THE DARK SPACE. BECAUSE OF THE LEAVY AMOUNTS OF RAIN OSLO RECEIVES, THE SLANTED ROOFS WILL COLLECT THE GREY WATER TO BE REUSED.

EXTRA UNIT USED FOR STORING RAKFISK AND ACCESSED BY RESIDENTS

EXTRA RAKFISK IS A NORWEGIAN FISH DISH MADE FROM TROUT OR SOMETIMES CHAR, SALTED AND FERMENTED FOR TWO TO THREE MONTHS, OR EVEN UP TO A YEAR, THEN EATEN WITHOUT COOKING. THE FISH IS PLACED UNDER A PRESSURE SEAL RESULTING IN A BRINE BEING FORMED AS THE SALT DRAWS MOISTURE FROM THE FISH. THE RAKFISK BUCKET IS STORED AT 4–8 DEGREES CELSIUS FOR ONE TO THREE MONTHS. THE GREY WATER THAT DRAINS FROM THE BUILDING WILL BE FILTERED AND PUMPED INTO A TANK USED TO HOLD FISH THAT WILL BE USED TO COOK RAKFISK. THE TANK WILL BE HELD IN A SPECIAL ROOM THAT DOESNT RECEIVE MUCH CONTACT FROM SUN AND CAN KEEP COOL DURING SUMMER AND WINTER.

AFTER ADJUSTING MY MODEL TO CAPTURE THE SOLAR RADIATION, I WAS ABLE TO ACHIEVE THREE DIFFERENT CLIMATES IN MY BUILDING. THE SPACE THAT HAS THE HIGHEST SOLAR RADIATION IS A GREEN ROOF USED FOR OUTDOOR ACTIVITY. THE SECOND AREA THAT STILL RECEIVES PLENTYFUL LIGHT WILL FUNCTION AS THE PUBLIC SPACES; LIVING, DINING. THE THIRD, DARKER ZONE WILL ACT AS THE PRIVATE SPACES; BEDROOMS, BATHROOMS.
