The covered atrium/lobby, with its sliding gridded glass roof, partially opens to aid passive, stack ventilation cooling during hot days, while sliding closed on cooler days to increase heat gain, thus warming the untreated atrium space, creating a more temperate buffer space between the chilly exterior and the warm interior spaces. South-facing photovoltaic panels line the stepped roofscapes to maximize southern exposure for energy collection. Also, the photovoltaic cells seasonally adjust their angles to optimize solar energy collection, which offsets electrical loads. Underground water storage cisterns are used to collect and reuse as much water as possible, though rainfall is sparse in the Long Beach climate. All spaces are excellent for daylighting and perform as purely daylit places in most climate conditions. The building, in essence, is the site.

The largest loss through the building’s envelope is through the north side windows. This is due to a higher U- Factor in the glazing. This was chosen strategically and allows for a greater amount of ambient or diffused light to enter from the north since the south is primarily concerned with preventing heat gain.

The design submitted for the competition further investigates the use of externally shaded windows and the amount of heat gain that can be avoided by choosing a glazing with a high U- Factor and a small SHGC. Also, the building utilizes high thermal mass walls which collect heat from the intense sun during the day and then releases the heat into the building at night lowering heat gain.

Technical Task 2.2 : Description of External Shading Wooden Trellis

Summer Conditions A wooden trellis, located on the south facade of the classrooms and shop rooms, not only gives the space an aesthetic character, but is also a strategic element in design. During the summer months, the trellis ZRXOGEHDSULPHORFDWLRQIRUVPDOOĂ&#x20AC;RZHULQJYLQHVWRJURZ:KHQ the vines are full, direct heat gain is greatly reduced and the space becomes an exterior place on the site that is thermally acceptable during a time when temperatures can be a bit warm . Since this area is cooler, the users within the classrooms can then open the doors to cool the internally loaded rooms through cross ventilation. The vines also diffuse GD\OLJKWUHGXFLQJWKHOLJKWLQJORDGLQWKHÂżUVWĂ&#x20AC;RRUVSDFHV

Winter Conditions During the winter, the trellis still blocks the direct solar gain from hitting the internally loaded spaces from the south. Since most of the vines ZLOOKDYHORVWWKHLUĂ&#x20AC;RZHUVRUIUXLWGXULQJWKHUDLQ\DQGVOLJKWO\FROGHU months, the ability arises to gain some solar heat, still making the space an ideal spot. Since the sun angles are low during the winter months, there is a screen provided to be completely operated by users. This screen will pull down to diffuse the direct beams and prevent an excess amount of heat gain.

Technical Task #2

Technical Analysis Task


Moveable Louvers and Windows

One of the main designed features throughout the building is the operable window system located on the south facades. This system contains moveable louvers as well as moveable window panes along a permeable track. This systems offers a variety of treatments depending on the environmental conditions. During the winter, for instance, the louvers may want to be moved out of the way to allow for solar heat gain to warm up the classroom spaces. When the louvers are moved during the winter, it allows for the low angle of the sun to penetrate directly into the classroom. To avoid glare, a rolled screen can be pulled down in the classroom, making desk area usable. However, since the outdoor temperature may not be ideal during the winter, the glass pane can remain closed, trapping the warmer air inside.

During summer months, it may be necessary to use the louvers to catch some of the solar heat before it enters the building. Since the classrooms and shop rooms are internally load dominated it is important that the building be able to breathe and release some of the heat. When this happens, the windows can slide out of place and cross ventilation can begin to happen throughout the building, cooling the spaces and the users.

Similarly to the previous louvers, these shading devices utilize VRPHRIWKHVDPHTXDOLWLHV,QVWHDGRIWKHKRUL]RQWDOVODQWV WKDWERXQFHDQGUHĂ&#x20AC;HFWOLJKWRQWKHVRXWKHUQZDOOWKHVHYHUWLFDO louvers are placed on the east and the west facing walls. Although it is typically not advised to place windows on these walls to begin with, some are unavoidable When open, these windows allow for both direct sunlight and solar heat gain to penetrate into a space to either warm or give daylight.

When closed, the louvers trap unwanted heat gain from entering the interior spaces. Also, direct daylight that can sometimes cause unwanted glare on desk surfaces is also differed by closing the louvers. Any additional unwanted daylight can then be caught by an interior pull down screen. Also, the large doors that close off the atria from the street, utilize the vertical louvers. This allows for sunlight and ventilation to reach these spaces even when the building is closed.

Passive Cooling Strategies may include:  

1. Shading the building from direct solar heat 8VLQJIDQVFDQFRRODVSDFHE\DOPRVW¿YHGHJUHHVWKLVUHTXLUHVWKHEXLOGLQJWRUHO\OHVVRQFRQYHQWLRQDODLUFRQGLWLRQLQJ %\RSHQLQJXSZLQGRZVDQGDOORZLQJWKHEXLOGLQJWR³EUHDWKH´RXWGRRUDLULVDOORZHGWRFLUFXODWHWKURXJKWKHVSDFH  cooling the building 4. Using a high thermal mass, absorbs a majority of the solar heat throughout the day and then releases it into the building at night, allowing space to not get overheated throughout the day when occupants are inside



Design Guidelines for Long Beach, California:

 

1. Heat gain from equipment, lights, and occupants will greatly reduce heating needs so keep home tight, well insulated (use ventilation in summer) 2. On hot days ceiling fans or indoor air motion can make it seem cooler by at least 5 degrees F thus less air conditioning is needed 3. For passive solar heating face most of the glass area south to maximize winter sun exposure, but design overhangs to fully shade in summer 4. This is one of the more comfortable climates, so shade to prevent overheating, open to breezes in summer, and use passive solar gain in winter 5. Window overhangs (designed for this latitude) or operable sunshades (extend in summer, retract in winter) can reduce or eliminate air conditioning 6. Sunny wind-protected outdoor spaces can extend living areas in cool weather 7. Lower the indoor comfort temperature at night to reduce heating energy consumption 8. Provide double pane high performance glazing (Low-E) on west, north, and east, but clear on south for maximum passive solar gain 9. A whole-house fan or natural ventilation can store nighttime â&#x20AC;&#x2DC;coolthâ&#x20AC;&#x2122; in high mass interior surfaces, thus reducing or eliminating air conditioning 2UJDQL]HĂ&#x20AC;RRUSODQVRZLQWHUVXQSHQHWUDWHVLQWRGD\WLPHXVHVSDFHVZLWKVSHFLÂżFIXQFWLRQVWKDWFRLQFLGHZLWKVRODURULHQWDWLRQ 11.

Good natural ventilation can reduce or eliminate air conditioning in warm weather, if windows are well shaded and oriented to prevailing breezes 14. Locate garages or storage areas on the side of the building facing the coldest wind to help insulate 15. Locate door and window openings on opposite sides of building to facilitate cross ventilation, with larger areas facing up-wind 16. Use light colored building materials and cool roofs (with high emissivity) to minimize conducted heat gain 17. High mass interior surfaces like stone, brick, tile, or slate, feel naturally cool on hot days and can reduce day-to-night temperature swings

The building really starts to work and breathe in the climate of Long Beach, California. By using thermal mass on the south facades, the building collects much of the solar heat throughout the day and then releases it back into the building during the night. This keeps the building from overheating when the occupants are using the space. Operability is also key. Not only do the louvers and windows move to allow for natural ventilation in the classrooms, but the roof and large doors on the atrium space do as well. When the building LVQRWEHLQJRFFXSLHGRUWKHZHDWKHULVUDLQ\DQGFROGWKHEXLOGLQJDQG³FORVH´XSDQGIXQFWLRQRQLWVRZQ+RZHYHUGXULQJDPDMRULW\ of the year, the building can operate without the use of conventional heating and cooling. The atria work with the windows and louvers to create shading devices and to help prevent overheated corridors.

Technical Task 3.3 : Analysis and Summary One goal of any net-zero building is the utilization of glazing and shading systems that will allow for high quality natural lighting while minimizing the negative thermal impact of the sun. Our building is no different in its goal, but varies in the execution. As many buildings will have, at minimum, a set system for shading and glazing systems, and occasionally will have a system that mechanically responds WRVSHFLÂżFHQYLURQPHQWDOHOHPHQWV2XUEXLOGLQJSXWVWKLVFRQWUROLQWKHKDQGVRIWKHXVHUV7KURXJKRXWWKHEXLOGLQJWKHUHDUHYDULRXV â&#x20AC;&#x2DC;hands-onâ&#x20AC;&#x2122; ways that the user can adjust their environments. This not only starts to account for human comfort variations, but also emphasizes the education of users on how the buildingâ&#x20AC;&#x2122;s systems work - a goal of an environmental training center. A student will learn hands-on that setting the system up in one orientation will cause the environment of the classroom to shift in comparison to another option (spaces can warm quickly, glare can strike on desk surfaces, etc.). Our building started as a response to the solar angles on the site, and has steadily maintained that course in keeping the sun as one of the primary driving forces in the design. Aside from rotating the building forms for late morning sun exposure, we have taken other steps LQDGDSWDWLRQRIIRUPWRDGGUHVVWKHVXQ%\VWHSSLQJXSWKHEXLOGLQJZHKDYHFUHDWHGDWULXPVSDFHVWKDWEHQHÂżWIURPDPELHQWOLJKWEXW rarely have to respond to the heat intensive, direct rays. Programmed spaces that are highest in interior heat gain like the auditorium and shop spaces, have been placed deep inside the space to completely eliminate direct solar gain. The building also responds to the need for daylight without solar heat gain by utilizing various shading systems through out the building. These systems are dependant not only RQWKHIDFDGHGLUHFWLRQEXWDOVREDVHGRQWKHORFDWLRQLQWKHIDFDGH$QH[DPSOHZRXOGEHWKHVWXGHQWORXQJHÂżUVWĂ&#x20AC;RRURQWKHQRUWK side of the atrium.

This allows for the classroom spaces to be warmed by direct solar gain when needed. To offset the potential glare produced by the sun, the shade screen can be pulled down from the interior side of the wall.

86.4 Btu/ ft2 per day x (area of glazing) = Total Heat Loss 86.4 Btu/ ft2 per day x (3,410 ft2) = 294,624 Btu/ day

Total Heat Gain - 4,085,180 Btu/day Total Heat Loss - 294,624 Btu/ day

Technical Task 4.3 : Analysis and Summary After doing these calculations on heat gain and loss through the southern glazing, it became clear that the amount of gain through the windows is exceptionally large relative to the loss through the same glazing surface.

The numbers highlighted in gray are design variables used to compare and contrast between the base case building and the competition case designs. These variables informed our architectural decisions. Further changes and adjustments were made during the design and development of the building. These excel tools were used in the preliminary development of the sustainable, architectural features, such as an exterior screen differing solar heat gain from the interior spaces.

1. January conditions include Atrium Spaces that are enclosed but not conditioned creating a warmer winter temperature in the Atrium Spaces. July conditions open the Atrium Spaces causing the temperatures inside the Atriums to be equal to the exterior temperatures. 2. Grouping the materials into north + east and south + west categories allows for variation in façade construction and glazing type. This allows for systems to maximize the efficiency of the façade with respect to orientation to the sun. sun See Part I: Technical Task #1 for U-Value Tables and Wall Assemblies. 3. Temperatures for January Exterior, January Interior, July Exterior, and July Interior are collected from Section 6 of the competition description. January Atrium temperature assumes a moderate winter temperature for the enclosed and unconditioned Atrium Spaces. This value was taken from MEEB (10th ed., Appendix Table B.1 p.1489) from Los Angeles that has a slightly warmer winter temperature.

1. January conditions include Atrium Spaces that are enclosed but not conditioned creating a warmer winter temperature in the Atrium Spaces. July conditions open the Atrium Spaces causing the temperatures inside the Atriums to be equal to the exterior temperatures. 2. Grouping the materials into north + east and south + west categories allows for variation in façade construction and glazing type. This allows for systems to maximize the efficiency of the façade with respect to orientation to the sun. sun See Part I: Technical Task #1 for U-Value Tables and Wall Assemblies. 3. Temperatures for January Exterior, January Interior, July Exterior, and July Interior are collected from Section 6 of the competition description. January Atrium temperature assumes a moderate winter temperature for the enclosed and unconditioned Atrium Spaces. This value was taken from MEEB (10th ed., Appendix Table B.1 p.1489) from Los Angeles that has a slightly warmer winter temperature.

4. Equation from MEEB (10th ed., Section 7.8(a) Design Heat Loss, p.203-204). 5. January exterior temperature for north and south facades are determined based on the room location. Facades that separate interior space from Atrium Space use the January Atrium temperature, facades located on an exterior surface use the January Exterior temperature. 6.

1. January conditions include Atrium Spaces that are enclosed but not conditioned creating a warmer winter temperature in the Atrium Spaces. July conditions open the Atrium Spaces causing the temperatures inside the Atriums to be equal to the exterior temperatures. 2. Grouping the materials into north + east and south + west categories allows for variation in façade construction and glazing type. This allows for systems to maximize the efficiency of the façade with respect to orientation to the sun. sun See Part I: Technical Task #1 for U-Value Tables and Wall Assemblies. 3. Temperatures for January Exterior, January Interior, July Exterior, and July Interior are collected from Section 6 of the competition description. January Atrium temperature assumes a moderate winter temperature for the enclosed and unconditioned Atrium Spaces. This value was taken from MEEB (10th ed., Appendix Table B.1 p.1489) from Los Angeles that has a slightly warmer winter temperature.

4. Equation from MEEB (10th ed., Section 7.8(a) Design Heat Loss, p.203-204). 5. January exterior temperature for north and south facades are determined based on the room location. Facades that separate interior space from Atrium Space use the January Atrium temperature, facades located on an exterior surface use the January Exterior temperature. 6.

January conditions include Atrium Spaces that are enclosed but not conditioned creating a warmer winter temperature in the Atrium Spaces. July conditions open the Atrium Spaces causing the temperatures inside the Atriums to be equal to the exterior temperatures. Grouping the materials into north + east and south + west categories allows for variation in façade construction and glazing type. This allows for systems to maximize the efficiency of the façade with respect to orientation to the sun. sun See Part I: Technical Task #1 for U-Value Tables and Wall Assemblies. Temperatures for January Exterior, January Interior, July Exterior, and July Interior are collected from Section 6 of the competition description. January Atrium temperature assumes a moderate winter temperature for the enclosed and unconditioned Atrium Spaces. This value was taken from MEEB (10th ed., Appendix Table B.1 p.1489) from Los Angeles that has a slightly warmer winter temperature.

January conditions include Atrium Spaces that are enclosed but not conditioned creating a warmer winter temperature in the Atrium Spaces. July conditions open the Atrium Spaces causing the temperatures inside the Atriums to be equal to the exterior temperatures. Grouping the materials into north + east and south + west categories allows for variation in façade construction and glazing type. This allows for systems to maximize the efficiency of the façade with respect to orientation to the sun. sun See Part I: Technical Task #1 for U-Value Tables and Wall Assemblies. Temperatures for January Exterior, January Interior, July Exterior, and July Interior are collected from Section 6 of the competition description. January Atrium temperature assumes a moderate winter temperature for the enclosed and unconditioned Atrium Spaces. This value was taken from MEEB (10th ed., Appendix Table B.1 p.1489) from Los Angeles that has a slightly warmer winter temperature.

1. January conditions include Atrium Spaces that are enclosed but not conditioned creating a warmer winter temperature in the Atrium Spaces. July conditions open the Atrium Spaces causing the temperatures inside the Atriums to be equal to the exterior temperatures. 2. Grouping the materials into north + east and south + west categories allows for variation in façade construction and glazing type. This allows for systems to maximize the efficiency of the façade with respect to orientation to the sun. sun See Part I: Technical Task #1 for U-Value Tables and Wall Assemblies. 3. Temperatures for January Exterior, January Interior, July Exterior, and July Interior are collected from Section 6 of the competition description. January Atrium temperature assumes a moderate winter temperature for the enclosed and unconditioned Atrium Spaces. This value was taken from MEEB (10th ed., Appendix Table B.1 p.1489) from Los Angeles that has a slightly warmer winter temperature.

4. Equation from MEEB (10th ed., Section 7.8(a) Design Heat Loss, p.203-204). 5. January exterior temperature for north and south facades are determined based on the room location. Facades that separate interior space from Atrium Space use the January Atrium temperature, facades located on an exterior surface use the January Exterior temperature. 6.

1. January conditions include Atrium Spaces that are enclosed but not conditioned creating a warmer winter temperature in the Atrium Spaces. July conditions open the Atrium Spaces causing the temperatures inside the Atriums to be equal to the exterior temperatures. 2. Grouping the materials into north + east and south + west categories allows for variation in façade construction and glazing type. This allows for systems to maximize the efficiency of the façade with respect to orientation to the sun. sun See Part I: Technical Task #1 for U-Value Tables and Wall Assemblies. 3. Temperatures for January Exterior, January Interior, July Exterior, and July Interior are collected from Section 6 of the competition description. January Atrium temperature assumes a moderate winter temperature for the enclosed and unconditioned Atrium Spaces. This value was taken from MEEB (10th ed., Appendix Table B.1 p.1489) from Los Angeles that has a slightly warmer winter temperature.

4. Equation from MEEB (10th ed., Section 7.8(a) Design Heat Loss, p.203-204). 5. January exterior temperature for north and south facades are determined based on the room location. Facades that separate interior space from Atrium Space use the January Atrium temperature, facades located on an exterior surface use the January Exterior temperature. 6.

January conditions include Atrium Spaces that are enclosed but not conditioned creating a warmer winter temperature in the Atrium Spaces. July conditions open the Atrium Spaces causing the temperatures inside the Atriums to be equal to the exterior temperatures. Grouping the materials into north + east and south + west categories allows for variation in façade construction and glazing type. This allows for systems to maximize the efficiency of the façade with respect to orientation to the sun. sun See Part I: Technical Task #1 for U-Value Tables and Wall Assemblies. Temperatures for January Exterior, January Interior, July Exterior, and July Interior are collected from Section 6 of the competition description. January Atrium temperature assumes a moderate winter temperature for the enclosed and unconditioned Atrium Spaces. This value was taken from MEEB (10th ed., Appendix Table B.1 p.1489) from Los Angeles that has a slightly warmer winter temperature.

January conditions include Atrium Spaces that are enclosed but not conditioned creating a warmer winter temperature in the Atrium Spaces. July conditions open the Atrium Spaces causing the temperatures inside the Atriums to be equal to the exterior temperatures. Grouping the materials into north + east and south + west categories allows for variation in façade construction and glazing type. This allows for systems to maximize the efficiency of the façade with respect to orientation to the sun. sun See Part I: Technical Task #1 for U-Value Tables and Wall Assemblies. Temperatures for January Exterior, January Interior, July Exterior, and July Interior are collected from Section 6 of the competition description. January Atrium temperature assumes a moderate winter temperature for the enclosed and unconditioned Atrium Spaces. This value was taken from MEEB (10th ed., Appendix Table B.1 p.1489) from Los Angeles that has a slightly warmer winter temperature.

Analysis: According the Base Case calculations, the building would actually be overheated for the month of January. By implementing simple design strategies (for example: wall systems with higher R - Values, shading devices over glazing, and increase the Daylight Factor) the building needs to be heated during the winter months. Additional fine tuning could be done to offset the heating need with solar heat gain.

*most gallons collected /month. Use for sizing.

Average rainfall by month is according to Climate Consultant, as listed in the Competition Statement, and then verified by www.weather.com. The average in inches was divided by 12 to turn the number into feet; after that, multiplied by an approximate roof area of 18,000 square feet to get the over all cubic feet of rain per month. Finally, that number was multiplied by the conversation rate of 7.5 to transform cubic feet into gallons. The gray bar denotes the months that receive the most rainfall and would require the largest cistern to collect and hold the precipitation.

Rounding up to 40,000 from 33,863 is quite a jump. However, with the months of January and February both receiving the most rainfall throughout the year, it is important to create space for overflow incase Long Beach receives more precipitation than the average. To keep sizing estimates simple, the overall 40,000 gallons was divided by five since there are five major rooftops which will be collecting a majority of the rainfall.

Part 2.2 : Why Xeriscaping? How the landscape of a site is designed can make or break the overall aesthetic of a building. For this site in Long Beach, California the site begs for a certain amount of local and native landscape to act and feel according to its surrounding climate. To accomplish this, xeriscaping techniques have been implemented into the design of the landscaping throughout the site. The word xeriscaping comes IURPWKH*UHHNZRUGV³[HURV´PHDQLQJGU\DQG³VFDSH´PHDQLQJ D YLHZ RU VFHQH  7UDQVODWHG WR OLWHUDOO\ PHDQ ³GU\ VFHQH´ xeriscaping is much more than dried dirt and cacti. Southern California receives a little more than 11 inches of rainfall annually with a high concentration of the precipitation falling during the winter months. This means that most all plants in this area must be draught tolerant to last through the summer. By using native plants that were made to sustain in these harsh conditions, owners do not have to worry about watering or tending to plants on a daily basis. By not watering during the dry season, owners will see an immediate cost savings through lower water bills. Also, xeriscaping typically requires less fertilizing and pest control measures than traditional landscapes. Using less of these, not only saves money, but does not introduce harmful toxins into the air and water stream.

The -DVPLQXP0XOWLĂ&#x20AC;RUXP is a shrubby and very fragrant vine found in Southern California. The Jasmine, as it is more commonly known as, is an evergreen shrubby vine that can grow up to ten feet tall and wide. This plant species tolerates draught to an extent, but would prefer to be watered in the summer, if possible. Placing this vine, and others in the smaller, open atrium near the shop classes will allow for an outdoor aesthetic but will provide shade and coverage to the students walking to and from class. By integrating a trellis and living plants into this space, it will also create interesting sun patterns in this space.

The Vitus Californica is known more commonly as the California Wild Grape. This deciduous vine adds a warm, vibrant color of red to any outdoor garden or trellis during the fall months. This vigorous vine can grow anywhere from three to six feet per year and also produces an abundance of fruit. However, while typically tasty, the grapes contain seeds and make for a better snack for animals and birds, rather than humans.

The Bougainvillea or the Paper Flower has a very burly type of vine and can be typically found in lower Florida and Southern California. Although this colorful vine adds character and color to any space, it does come with thorns that run up and down the burly vine; pruning can be an issue.
