ABSTRACT The adverse climate conditions of Central Iran, characterized by long, hot and dry summers and cold winters, resulted in distinctive climateresponsive building traditions in cities such as Yazd, Shiraz and Esfahan. These vernacular traditions often take advantage of the thermal properties of locally available building materials, such as mud brick, coupled with a strong understanding of diurnal temperature shifts, seasonal wind temperatures and controlled access to solar radiation to create indoor micro-environments that often substantially deviate away from the thermal stress present in the outdoor environment. The most prevalent traditional housing typology in the region, the central courtyard house, is a notable example of such design traditions. The placement of the courtyard and its clear view of the sky provides each room (Persian: otagh) that surrounds the courtyard with varying degrees of exposure to the outdoor climate. These differentiations create a series of seasonal rooms with unique thermal responses to climatic variations over the course of the year. By creating a comprehensive thermal-comfort-based occupancy map of the seasonal rooms as an interconnected network of spaces within the central courtyard house, this study analyzes the effectiveness of the system, as a whole, in providing annual indoor thermal comfort through passive means in climates in which majority of outdoor hours are uncomfortable. The results are supplemented by an in-depth sensitivity analysis that illustrates the extent to which a seasonal room’s orientation, materiality and exposure to outside climate elements affects its thermal behavior over the course of the year.

INTRODUCTION
THE TRADITIONAL CENTRAL COURTYARD HOUSES OF IRAN The adverse climate conditions of Central Iran, characterized by long, hot and dry summers and cold winters, resulted in distinctive climateresponsive building traditions evident in the vernacular dwellings of cities such as Yazd, Shiraz, and Esfahan. The process took advantage of the thermal properties of locally available building material, such as mud bricks, coupled with a strong understanding of diurnal shifts, seasonal wind temperatures and directions and controlled access to solar radiation to improve indoor thermal conditions. The results were mosques, bazaars, caravanserais and houses with indoor microenvironments that often substantially deviated away from the thermal stress present in the outdoor environment. The most prevalent housing typology in the region (Foruzanmehr, 2014), the central courtyard house, is a notable example of the local building design traditions imbued with Persian culture’s intricacies. On an urban scale, Iranian central courtyard houses, often single-story, form clusters of dense buildings with touching perimeters accessible with narrow alleys from the main streets (Memarian & Brown, 2003). The dense formation of the buildings helps shade the public alleys while minimizing the surface area exposed to solar radiation. Traditionally, adobe and mud brick were the main building materials, supplemented by baked bricks in the past century (Memarian & Brown, 2003).

The central courtyard, open to the sky, is enclosed by rooms (Persian: otaghs) that typically open up into the courtyard (Foruzanmehr, 2014; Memarian & Brown, 2003) on two, three or all four sides. Many spaces, such as the talar and the ivan have specific climate-related functions (Memarian & Brown, 2003). The shaded semi-outdoor talar on the south of the courtyard acts as a transitional space into a summer room and has a basement (Persian: zirzamin) underneath (Memarian & Brown, 2003). The zirzamin, often the coolest space in the house, acts as a thermal shelter for the family in the hottest days of summer (Memarian & Brown, 2003). Because of their modularity and the small amount of furniture, rooms offered the flexibility to change function according to daily or seasonal variations (Memarian & Brown, 2003) expanding the adaptability of the house in response to climate and programmatic usability. These vernacular strategies, refined over centuries of cultural and architectural adaptations, are currently in a state of decline and negligence. Over the past few decades, the central courtyard typology has quickly disappeared from the local building palette in favor of other ‘modern’ counterparts (Foruzanmehr & Vellinga, 2011). The outcome is an urban fabric with generic buildings that hardly respond to the cultural context, the climate and the geographical location that are constructed in. Failing to mitigate the outside, the new buildings rely on tremendous amounts of resources to provide thermally comfortable indoor environments. Source: arthut.co

INTRODUCTION
KNOWLEDGE GAP The existing literature on the thermal properties of the traditional Iranian central courtyard house is often divided into two main categories. One commonly found viewpoint, seen over the past few decades, describes this vernacular typology as a response to the local climatic conditions and focuses on the architecture and the building traditions of the culture. Von Hardenberg (1982) intricately defines his observations of the design principles of the Lari house in Yazd and the Mosavarolmolki house in Esfahan in regards to solar response and airflow control (Von Hardenberg, 1982). Taghi (1990) describes the characteristics on traditional houses in Ardakan in response to the desert climate (Taghi, 1990). Memarian and Brown (2003) look into a number of historic dwellings is Shiraz and Yazd to identify the link between the impacts of climate and religion in shaping the central courtyard typology (Memarian & Brown, 2003). While this body of work provides essential insights into the climate-responsive design strategies of the typology, it does not support the findings with appropriate thermal data or measurements.

A second more scientific approach, rising in the recent years, aims to quantify the thermal performance of these structures through modern techniques and analysis tools. Majority of the research in this area has been conducted by Bahadori, Yaghoobi and Foruzanmehr. Bahadori and Yaghoobi (2007) analyze the thermal effects of ventilation and natural cooling systems in the traditional buildings of Iran. Foruzanmehr (2012)

evaluates summer-time thermal comfort in a series of central courtyard houses in Yazd at two typically hot periods of the year (Foruzanmehr, 2012). Additionally, Foruzanmehr (2014) investigates the practicality of separate summer and winter rooms present in the typology (Foruzanmehr, 2014). Because of the rapid disappearance of the central courtyard typology in modern architecture of Iran, these investigations on the thermal performance of such houses is often based on short durations (e.g. weekly) of thermal data collected from still standing historic structures in their present form. As a result, annual analysis is typically not present. Without thermal data covering the course of the whole year, the complex thermal behavior of the typology could be greatly distorted. For instance measurements from ‘the design weeks’, perhaps biased based on modern day energy needs and requirements, provide a undervalued image of the central courtyard house as a combination of isolated spaces.

INTRODUCTION
PROPOSAL In order to bridge the present knowledge gap, this research aims to link thermal comfort to not only the climate and the architectural characteristics of the typology but also to the specific usage patterns and seasonal adaptations of the culture that inhabited the building. On-site thermal measurements (Foruzanmehr, 2012; Foruzanmehr, 2014) and preliminary thermal simulations by the author suggest that as an isolated element, a single space within the house is thermally comfortable only at certain times but not throughout the year. Considering that inhabitants traditionally followed a micro-migratory pattern between different spaces within the house, the goal of this thesis study is: A. Develop an appropriate methodology for analyzing the thermal behavior of the traditional Iranian central courtyard typology. B. Create a comprehensive comfort map of the seasonal rooms as a network of spaces to understand whether such seasonal spaces, as a whole system, succeed in providing annual thermal comfort in a climate where majority of the outdoor hours are uncomfortable. C. Analyze the design flexibility of the typology (e.g. building orientation, materiality, glazing ratio) through an in-depth sensitivity study while maintaining its intended thermal behavior. D. Examine the validity of the methodology in a different climate.

METHODOLOGY
THERMAL COMFORT This study relies on linking thermal comfort to overall spatial occupancy and migratory patterns of the inhabitants. As a result, a clear understanding of the concepts related to thermal comfort play a crucial role throughout the research. Thermal comfort is defined as “that condition of mind which expresses satisfaction with the thermal environment� (ASHRAE, 2013). This means that the person would be unconscious of how the body is losing heat to the environment (Grondzik, Kwok, Stein, & Reynolds, 2009). According to Povl Ole Fanger, air temperature, mean radiant temperature, relative air velocity and humidity (vapor pressure in ambient air) are the four main measurable environmental factors constituting the thermal environment. Measurable personal factors that influence the human thermal comfort include activity level and thermal resistance of clothing (Fanger, 1973; Grondzik et al., 2009). In addition to measurable environmental and personal factors, other personal factors such as the ability to migrate to a more comfortable place also affect our thermal comfort but are more difficult to quantify (Grondzik et al., 2009). These factors, while being familiar tools of the designer, are neglected because of difficulty in quantification (Grondzik et al., 2009) and often ignored in thermal analysis and simulations. While in the state of thermal discomfort, transitioning away from the thermal stress resulted
15
by the uncomfortable environment is felt as pleasant (ASHRAE, 2013). As a result, a person’s ability to adapt to the thermal environment is another aspect influencing the human thermal comfort. These adaptations include a series of three processes: physiological adaptations, psychological adaptations and behavioral adjustments (Yau & Chew, 2014). Because of the biological processes, the human body generates heat as a by-product. This additional heat must be dissipated from the system in order to maintain almost constant internal temperatures and prevent overheating or hyperthermia (ASHRAE, 2013; Lechner, 2009). Similarly, excessive heat loss can result in unnecessary body cooling or hypothermia (ASHRAE, 2013). An internal temperature of approximately 37°C (98.6°F) is constantly maintained by the hypothalamus, an area at the base of the brain that produces hormones that, among many other tasks, regulate body temperature (Lechner, 2009; Wisse, 2013). The hypothalamus’s hot and cold sensors read the average internal body temperature from arterial blood and through additional sensors in the skin (ASHRAE, 2013). Controlling blood flow to the skin in response to deviations from set-point temperatures is the most common physiological process used in order to regulate body temperature (ASHRAE, 2013). While it is critical that core body temperatures be maintained at approximately 37°C, the temperature of the skin and extremities can vary largely (Blazejczyk et al., 2013). When internal temperatures go above the set point, vasodilation increases blood flood to
16
the skin to maximize heat loss to the environment. Reversely, when internal temperatures fall below the set point, vasoconstriction minimizes heat loss to the environment through reduced blood flow to the skin (ASHRAE, 2013). Heat Loss from the human body is through a combination sensible and latent heat losses. As internal temperatures raise farther about the setpoints, sweating promotes heat loss through latent processes (ASHRAE, 2013). After the water in sweat evaporates, the remaining salt on the skin reduces the vapor pressure of water and delays evaporation of additional sweat (ASHRAE, 2013). This results in increased wetness of the skin. Energy Balance Formula (ASHRAE, 2013) M - W = q_sk + q_res + S M - W = (C+ R+E_sk ) + (C_res+E_res ) + (S_sk+S_cr) Where M= rate of metabolic heat production, W/m2 W= rate of mechanical work accomplished, W/m2 Q_sk= total rate of heat loss from skin, W/m2 Q_res= total rate of heat loss through respiration, W/m2 C+R= sensible heat loss from skin, W/m2 E_sk= total rate of evaporative heat loss from skin, W/m2 C_res= rate of convective heat loss from respiration, W/m2 E_res= rate of evaporative heat loss from respiration, W/m2 S_sk= rate of heat storage in skin compartment, W/

METHODOLOGY
PERSONAL FACTORS Most of the heat produced because of the human body’s biological processes is released to the environment through the skin; as a result, metabolic activity is characterized by the amount of heat produced per unit area of skin (ASHRAE, 2013). This heat is approximately 100 W for a resting adult male. Since the average European male has a body surface area of approximately 1.8 m2, he dissipates about 58.1 W/m2 of body surface area at rest (Lechner, 2009). 58.1 W/m2 defines 1 met, the unit of metabolic rate. The chart here shows some of the common activities performed in a house and their corresponding heat generations and metabolic rates.

Clothing minimizes heat transfer through conduction, convection and radiation from the body to the surrounding environment. Insulation properties of clothing are measured in clo units (Grondzik et al., 2009). The concept of clo was developed in 1941 based on the clothing insulation value of the typical American man’s business suit during that period and is equal to 1.55 m2 K/W (Grondzik et al., 2009). Insulation value of clothing can be estimated based on weight at 0.35 clo per kilogram of clothing (Grondzik et al., 2009). As mentioned, this methodology introduces migration to a more comfortable space as a third personal factor affecting

METHODOLOGY
PMV VS. ADAPTIVE COMFORT In this section, we compare two widely accepted thermal comfort models to understand their benefits and downfalls. Taking into account the characteristics of each model together with the intentions of the research, we then identify the adaptive comfort model as the most appropriate method for this study. Povl Ole Fanger (1934-2006) created the Predicted Mean Vote (PMV) in 1970 based on climate chamber and laboratory studies on human subjects (Charles, 2003). An advantage of the PMV model is that it has the flexibility to take into account the four major environmental variables (air temperature, mean radiant temperature, relative air velocity and humidity) and the two main personal factors (activity level and clothing) that affect thermal sensation (Charles, 2003; Fanger & Toftum, 2002). The physiological scale used in the PMV model ranges from cold (-3) to hot (+3) in which neutral (0) is the midpoint of the scale (Fanger, 1973). The Predicted Percentage of Dissatisfied (PPD), which quantifies the degree of discomfort, is then determined as a function of PMV (Fanger, 1973). The PPD curve created by Fanger in 1970 is based on studies compromising 1300 human subjects (Fanger, 1973). According to Fanger, because of the biological variance in a group of people, it may not be possible to provide thermal satisfaction for everyone at the same time in the same space (Fanger, 1973). The minimum value in the PPD curve, five percent, is the lowest percentage of dissatisfied persons that can be expected from this model (Fanger, 1973).
19
Therefore, the aim is to provide the highest possible percentage of thermally comfortable occupants. The adaptive comfort model was first proposed in the 1970s and is based on findings of field surveys of human subjects in their normal surroundings (Yao, Li, & Liu, 2009). It relies on the following adaptive principle: If a change occurs such as to produce discomfort, people react in ways which tend to restore their comfort (Nicol, 2011; Yao et al., 2009). Field studies have shown that the PMV method does not provide an accurate thermal sensation for occupants of naturally ventilated buildings (Brager & de Dear, 1998; Nicol, 2011; Yau & Chew, 2014). The adaptive comfort model aims to present a solution to concerns regarding the failure of the heat balance comfort models to define a range of comfortable temperatures in naturally ventilated buildings where indoor temperature are more variable (Nicol, 2011). This method takes into account a series of three adaptive processes: physiological adaptations, psychological adaptations and behavioral adjustments (Yau & Chew, 2014). Physiological adaptation includes vasodilation, vasoconstriction and perspiration (Yao et al., 2009; Yau & Chew, 2014). Psychological adaptation is based on thermal perception shaped by past experiences and the reduction of thermal sensitivity over a period of exposure to a certain thermal level (de Dear & Brager, 2002; Yau & Chew, 2014). Behavioral adjustments are possible personal actions that change the body’s heat balance in order to achieve
20
thermal comfort (Yau & Chew, 2014).

METHODOLOGY
WHY COMPUTERIZED SIMULATIONS? In order to obtain appropriate thermal data for the study, the base case is to be analyzed in conditions comparable to the typology’s original design, occupancy and building use conditions. As a result, it is necessary to have access to hourly thermal data over the course of a full year throughout the study. Through a series of precedent studies, it became evident that for the remaining stock of the traditional central courtyard typology, the original conditions have been modified in various forms. A. Building layout: because of the old age of these structures, some have fallen into despair. In many of the still occupied examples, the architectural layout and physical characteristics of the building have been modified. B. Building occupancy and use: present occupancy and buildings use is different. C. Building systems: mechanical cooling and heating systems have replaced the passive systems and the building is not operated as originally intended. To resolve these complications, computerized methods are used to simulate the thermal behavior of the typology based on the original use (residential), occupancy and without active mechanical systems.

SEASONAL ROOMS
SECTION OVERVIEW This section provide a detailed insight into the year-round thermal behavior of each seasonal room. The five seasonal rooms include the summer room, the east facing room, the winter room, the west facing room and the basement. The thermal behavior of each seasonal space is often unique reflecting the characteristics of the traditional central courtyard typology. Hourly operative temperature is calculated based on hourly air temperature and mean radiant temperature for each space over the course of the whole year. Outdoor air temperatures and operative temperatures are then used to calculate adaptive thermal comfort for each space.
3.1
SEASONAL ROOMS
THE SUMMER ROOM
THERMAL BEHAVIOR AND COMFORT Traditionally, the thermal intentions behind the design of the summer room or the summer section (Persian: tabestan neshin) of a larger house has been to deviate away from the high thermal stress of the outside during the months of June to September when nearly all other spaces within the house fail to do so. The summer room takes advantage of different strategies to reduce heat gains. Because of its placement to the south of the courtyard and the adjacent semi-outdoor transitional space, the north facing summer room is self-shading throughout the year and diffused daylight access ensures minimal solar heat gains. Having the highest floor to ceiling height among all the spaces within the house further results in an optimal temperature gradient as hot air rises above the occupied portion of the room. The effect of the thermally massive walls together with night cooling and diurnal shifts result in mean radiant temperatures that are often below the air temperature during the summer. Accordingly, as illustrated in the graphs, the summer room’s operative temperature is often lower than the indoor air temperature during the hottest months of the year. The number of hours in the lower range of below 16°C indicates an annual percentage decrease from 45.1% (outdoor air) to 23.9% (summer room operative) with majority of hours during coldest periods of the year from December to March. The number of hours in the mid-lower range of 16°C to 20°C show an annual percentage increase from 11.7% (outdoor air) to 17.8% (summer

This shows an improvement in indoor conditions as majority of the outdoor hours during these colder months of the year fall below 16°. The number of hours in the optimum range of 20°C to 26°C indicates an annual percentage increase from 18.2% (outdoor air) to 33.3% (summer room operative) with majority of hours from April to June and September To November.

During the spring, majority of the indoor hours meet the adaptive comfort criteria resulting in a seasonal comfort of 79.0%. During the summer, the thermal behavior of the summer room shows a clear seasonal differentiation compared to the rest of the year with the largest percentage of comfortable hours at 89.5%. The results prove that the summer roomâ&#x20AC;&#x2122;s thermal behavior is as intended providing thermal comfort for majority of the hours during the hot periods of the year. As shown in the adaptive comfort chart, the space fails to meet the adaptive comfort criteria only in approximately 10.5% of the hours of the summer belonging to the hottest afternoons in July and August. During the fall, the summer roomâ&#x20AC;&#x2122;s seasonal comfort is at 63.2%. From mid-November as majority of the outdoor hours begin to fall below 16°C, the summer room starts to feel cold.

SEASONAL ROOMS
THE EAST FACING ROOM
THERMAL BEHAVIOR AND COMFORT Traditionally, the east and west facing sections of the central courtyard house were allocated to secondary functions such as sleeping areas and storage. The orientation of the east facing room results in a non-symmetrical thermal behavior as it receives maximum solar exposure during the morning hours with no direct exposure during the afternoon hours. Because of their less significant programmatic functions, the east and west facing rooms are often smaller in size and have the lowest floor to ceiling height among all above ground spaces. When we compare the thermal behavior of the east facing room to the outside, the number of hours in the lower range of 16°C and below indicates an annual percentage decrease from 45.1% (outdoor air) to 24.3% (east facing room operative) with majority of hours belonging to the coldest periods of the year from December to March. The number of hours in the mid-lower range of 16°C to 20°C shows a slight annual percentage increase from 11.7% (outdoor air) to 12.7% (east facing room operative) with majority of hours during the early mornings and evenings from March to April and during the afternoons from mid-November to December. The number of hours in the optimum range of 20°C to 26°C indicates an annual percentage increase from 18.2% (outdoor air) to 30.7% (east facing room operative) with majority of hours from April to mid-May and mid-September to mid-

The number of hours in the upper range of above 30°C has a slight annual percentage decrease from 14.8% (outdoor air) to 12.3% (east facing room operative) with majority of hours during the afternoons and early-evenings of June to September. By comparing the outdoor air temperature chart to the operative temperature chart, it becomes evident that during the hottest periods of the summer, the east facing room drastically underperforms compared to the summer room and at points creates indoor conditions that are worse than the outside. The adaptive comfort calculations for the east facing room show that the majority of thermally comfortable hours are from March to midNovember. When compared to the summer room, the east facing room begins to provide comfortable conditions earlier in the year beginning in the last month of winter. In the winter, the east facing room has a low seasonal comfort percentage of 18.9% with no hours meeting the adaptive comfort criteria during from December to late-February. However, this percentage is still higher than the summer room’s performance (14.2%) during the same period.

During the spring, the east facing room shows its highest percentage of comfortable hours compared to the rest of the year at 85.5% of the season outperforming the summer room (79.0%) during the same period. This indicates that the east facing room can act as one of the most comfortable spaces in the central courtyard house during majority of the spring. Throughout the summer, the east facing room fails to meet the adaptive comfort criteria during the hot afternoon hours resulting in a seasonal comfort of 55.2% drastically underperforming compared to the summer room (89.5%). During the fall, the east facing roomâ&#x20AC;&#x2122;s seasonal comfort is at 66.3%. This does not match performance of the space during the spring because of the lower fall temperatures but is still slightly higher than the summer roomâ&#x20AC;&#x2122;s performance (63.2%) during the same period.

SEASONAL ROOMS
THE WINTER ROOM
THERMAL BEHAVIOR AND COMFORT Traditionally, the thermal design of the winter room or the winter section (Persian: zemestan neshin) of a larger house aims to minimize or eliminate the need for space heating in the cold periods of the year. This is achieved through the placement of the space to the north of the central courtyard resulting in a south-facing orientation that maximizes solar exposure during the coldest months of the year by allowing the low-angle winter sun to penetrate deep into the space. The thermally massive envelope helps keep the heat from sun and other internal gains (e.g. occupancy) for a longer period of time. Additionally, because of the thermal mass effect, the operative temperature is typically higher than the air temperature during the coldest periods of the year. In contrast to the summer room, the winter room takes advantage of a lower ceiling height in order to keep the hot air from rising above the occupied portion of the room. Comparing the thermal behavior of the winter room to the outside, the number of hours in the lower range of below 16°C shows a significant annual percentage reduction from 45.1% (outdoor air) to 1.9% (winter room operative) minimizing the lower range of temperatures that contribute to the need for space heating. This percentage (1.9%) is drastically different than those of the summer room (23.9%) and the east facing room (24.3%). These figures prove the effectiveness of the winter room in increasing and maintaining higher indoor temperatures in the coldest months of the year during which other seasonal rooms fall well below 16°C.

Overall, the winter room has the largest percentage of overall annual comfort compared to the summer room and the east facing room. During the winter, the winter room has a seasonal comfort percentage of 68.2% highly outperforming the summer room (14.2%) and the east facing room (18.9%) during the same period but still unable to eliminate the need for heating throughout the whole season. During the spring, the winter room shows a very high percentage of comfortable hours at 95.2% of the season outperforming the summer room (79.0%) and the east facing room (85.5%). In the summer, the winter room fails to meet the adaptive comfort criteria during most of the hot afternoon hours resulting in a seasonal comfort of 69.0% with a much lower performance compared to the summer room (89.5%); however, the winter room still outperforms the east facing room (55.2%) during the summer. In the fall, the winter room reaches a substantial seasonal comfort of 97.9% practically maintaining comfortable temperatures throughout the whole season which is significantly higher than the summer room (63.2%) and the east facing room (66.3%) during the same period.

SEASONAL ROOMS
THE WEST FACING ROOM
THERMAL BEHAVIOR AND COMFORT Similar to the east facing room, the west facing section of the central courtyard house often serves secondary functions. Because of its west facing orientation, it has a non-symmetrical thermal behavior as it receives minimal solar exposure during the morning hours but maximized direct exposure during the late afternoon hours. Because of its less significant programmatic functions, the west facing room follows the same spatial design characteristics as the east facing room and is often smaller in size and has a low ceiling height. In some examples, the west facing section of the courtyard house is completely omitted and replaced by false walls. When we compare the thermal behavior of the west facing room to the outside, the number of hours in the lower range of 16°C and below shows an annual percentage reduction from 45.1% (outdoor air) to 19.2% (west facing room operative) reducing the lower range of temperatures that contribute to the need for space heating. The majority of the hours for this range are from mid-December to lateFebruary. The number of hours in the mid-lower range of 16°C to 20°C has a annual percentage increase from 11.7% (outdoor air) to 15.8% (west facing room operative) with majority of the hours from midNovember to mid-December and during the early mornings and late-evenings in March.

The number of hours in the mid-upper range of 26°C to 30°C shows an annual percentage increase from 10.2% (outdoor air) to 19.6% (west facing room operative) with majority of the hours beginning from the afternoons in April and ending during the afternoons in October. The number of hours in the upper range of above 30°C shows a slight annual percentage decrease from 14.8% (outdoor air) to 13.2% (west facing room operative) with majority of hours during the afternoons and evenings of June to early September. This indicates that similar to the east facing room, the west facing room severely underperforms in reducing temperature ranges during the hottest hours of summer. As illustrated in the adaptive comfort graph for the west facing room, annually, the majority of thermally comfortable hours are from March to midNovember as well as some afternoon hours until mid-December. In the winter, the west facing room has a comfort percentage of 21.5% of the hours of the season outperforming the summer room (14.2%) and the east facing room (18.9%) while underperforming compared to the winter room (68.2%) during the same period.

However, the roomâ&#x20AC;&#x2122;s spring comfort percentage is well below that of the winter room (95.2%). In the summer, the west facing room does not meet the adaptive comfort criteria during majority of the afternoon and early-evening hours resulting in a seasonal comfort of 55.3%. This is well below the performance of the summer room (89.5%) yet nearly identical to the east facing room (55.2%). The west facing roomâ&#x20AC;&#x2122;s summer comfort percentage is also lower than the winter room (69.0%). During the fall, the west facing room has a seasonal comfort of 71.8%.

SEASONAL ROOMS
THE BASEMENT
THERMAL BEHAVIOR AND COMFORT Among the seasonal spaces within the central courtyard house, the basement has a unique thermal behavior. Traditionally, the basement acts as a thermal shelter in the hottest afternoons of the summer during which no other space is thermally comfortable. Deeper into the ground, soil temperatures become more uniform throughout the year nearing the mean annual outdoor air temperature. Because of the adjacency of its walls and floors to the ground, thermally massive surfaces and minimal to no exposure to direct sun, the basement maintains uniform temperatures throughout the year. As illustrated in the operative temperature graph, the basement practically eliminates the lower range of below 16°C, the mid-upper range of 26°C to 30°C and the upper range of above 30°C and reduces the mid-lower range of 16°C to 20° form 11.7% (outdoor air) to 6.7% (basement operative) of the hours of the year. The most impressive improvement is the increase in the optimum range of 20°C to 26°C from 18.2% (outdoor air) to 93.3% (basement operative) of the hours of the year. This results in the near uniform annual temperature range that the basement benefits from. Based on the adaptive comfort calculations for the basement, annually the majority of thermally comfortable hours are from late-August to late May. In the winter, the basement reaches a comfort percentage of 100.0% of the hours of the season outperforming the summer room (14.2%), the

During the spring, the basement has a seasonal comfort percentage of 86.7% outperforming the summer room (79.0%) and showing a slight improvement compared to the east facing room (85.5%) and west facing room (83.7%) during the same period; however, the basement’s spring comfort percentage is below the 95.2% for the winter room. Interestingly, in the summer, the basement shows the low percentage of comfort at 43.7% of the season. This is well below the performance of the summer room (89.5%), the east facing room (55.2%), the winter room (69.0%) and the west facing room (55.3%) during the same period; however, a drastic difference in this case is that based on the adaptive comfort criteria, the basement is the only space that feels too cold during the hottest hours of the year. This is a significant deviation separating the basement’s thermal behavior from other seasonal spaces as all others do not meet the adaptive comfort criteria because of overheating. In a way, in this specific case, the basement still acts as a cool shelter during the hottest hours of the summer. During the fall, the basement once again reaches a seasonal comfort percentage of 100% outperforming the summer room (63.2%), the east facing room (66.3%), the west facing room (71.8%) and even the winter room (97.9%) during the same

period of the year. Analyzing the seasonal comfort percentage, it is crucial to take into consideration that while the basement often manges to outperform the thermal behavior of other seasonal rooms, because of its less-than-optimal spatial qualities such as minimal access to daylight, it may not permanently replace the spatial functions of the above ground spaces. The ultimate spatial purpose of the basement is to fill the thermal comfort gap during the times in which all other above ground rooms fail to do so. Traditionally, because of its low temperatures, the basement also served as a space for storing food and perishable material. Thermally, the existence of the basement further contributes to an improvement in the thermal performance of the above ground rooms as a result of its uniform temperatures throughout the year.

Comparing the indoor operative temperature ranges for all spaces to the outdoor air temperature ranges, it becomes evident that overall all seasonal rooms provide indoor environments that largely deviate away from the thermal stress present in the outdoor environment. This level of deviation, however, is dependent on the thermal and design characteristics of each room.

When comparing the lower temperature range of below 16°C, which often results in the need for heating, the outdoor percentage of 45.1% is reduced to 23.9% in the summer room, 24.3% in the east facing room, 1.9% in the winter room, 19.2% in the west facing room and 0.0% in the basement. The results indicate that while all rooms have an improved thermal condition compared to the outside environment, the winter room and the basement have the most optimum performance in reducing the number of hours that contribute to the need for heating. When comparing the upper temperature range of above 30°C, which often results in the need for cooling, the outdoor percentage of 14.8% is reduced to 4.7% in the summer room, 12.3% in the east facing room, 8.5% in the winter room, 13.2% in the west facing room and 0.0% in the basement. Accordingly, the summer room and the basement have the most optimum performance in reducing the number of hours that contribute to the need for cooling.

The product of the developed methodology that takes into account a thermal-comfort-based migration pattern in the central courtyard house together with thermal and comfort data for all seasonal rooms is the whole system comfort-based occupancy map shown at the top left. Using the chart, we can test out the original thesis question of whether the central courtyard house as a whole system can provide annual thermal comfort. As observed in the graph, the system, as a whole, provides thermal comfort for 98.9% of the year practically covering

ORIENTATION
SECTION OVERVIEW Traditionally, the Iranian central courtyard typology relies only on passive climate-responsive strategies to mediate the outside climate. Accordingly, the typologyâ&#x20AC;&#x2122;s construction on a north-south axis plays an important role in its thermal behavior. The north facing summer room is exposed to minimal direct solar radiation to reduce unwanted heat gains while the winter roomâ&#x20AC;&#x2122;s south facing orientation allows for maximum direct solar exposure. The east facing room has a greater solar heat gain in the mornings while the west facing room is exposed to direct sun in late afternoons. As a result, solar orientation is one of the primary elements that shapes the daily and seasonal thermal variations in each space. This section analyzes the thermal effects of solar orientation and a deviation from the north-south for each seasonal room. The aim is to understand how limitation in selecting the most optimum orientation, for instance in a dense urban fabric or grid system, can affect the overall performance of the system. The provided adaptive comfort charts in the following sections provide details on the thermal effects of a deviation from the true north-south access. The chart at the top of the page or the base case is based on an exact north-south orientation for the central courtyard house. The three charts show the effects of orientation deviations at 15 degree increments on seasonal thermal comfort.

Among all the above ground seasonal rooms, the summer room receives minimal to no direct solar radiation throughout the year. As explained in the Seasonal Rooms section, this is one of the reasons behind the space’s minimal overheating during the hot summer months. However, the north facing orientation also contributes to the room’s lower than average temperatures during the colder months. As a result, seasonal thermal comfort in the summer room shows minimal to no changes as a result of 15, 30 or 45 degree deviations of the central courtyard house from the north-south axis toward the east direction. The space’s base winter occupancy of 14.2% (true N-S) shows minimal to no change at 15° E (14.2%) or 30° E (14.1%) and a slight increase to 15.0% at 45° E. The space’s base spring occupancy of 79.0% has a slight increase to 79.3% at 15° E, 80.2% at 30° E and 81.1% at 45° E.

Overall, seasonal thermal comfort in the summer room, especially during the summer, shows greater differences as a result of deviations of the central courtyard house toward the west direction. This is most likely the result of overheating due to exposure to the west sun during the hot lateafternoons in the summer. On the other hand, the smaller percentage change caused by a deviation toward the east direction is most likely the result of the lower morning temperatures that reduce the risk of overheating even after exposure to the morning sun. As a result of an orientation deviation toward west, the summer room’s winter occupancy of 14.2% in the base case (true N-S) shows a slight decrease to 14.0% at 15° W and 13.9% at 30° W. Winter comfort shows a slight increase to 15.9% at 45° W. The summer room’s spring comfort of 79.0% in the base case has a slight decrease to 78.7% at 15° W. Spring comfort has a slight increase to 79.8% at 30° W and 82.6% at 45° W.

Because of its orientation, the east facing room receives a larger amount of direct solar exposure in the morning and minimal exposure in the evening. As a result of a deviation of the central courtyard house from the north-south axis toward the east direction, the space’s seasonal thermal comfort shows an overall improvement leading to increased seasonal occupancy percentages. This is a result of a greater exposure of the space to direct radiation during the cooler morning hours as the sun rises in the sky. The room’s summer comfort shows negligible changes as a result of these deviations.

Overall, the basement’s seasonal comfortbased occupancy shows insignificant differences throughout the year except for the summer during which the space largely benefits from a deviation of the central courtyard house from the north-south axis toward the west direction. This is a result of higher temperatures with additional heat gains from the above-ground spaces that transform some of the summer hours in the basement from cold to thermally comfortable. As a result of a deviation of the central courtyard house from the north-south axis toward the west direction, the thermal comfort calculations for the basement indicate the following results: The space’s base winter occupancy of 100.0% (true N-S) remains unchanged with 100.0% at 15° W, 100.0% at 30° W and 100.0% at 45° W.

THE SUMMER ROOM
INCREASE IN THERMAL MASS The thermal analysis data for the summer room indicates that as a result of an increase in the amount of thermal mass, the seasonal comfort based occupancy in the space is improved except during the coldest months of the year in which a reduction in performance is observed. The largest improvements are during summer and spring occupancy. The increase in summer occupancy is specifically notable as it makes the summer room practically comfortable throughout the whole season. The thermal comfort and occupancy findings are illustrated in the graphs on the left and can be summarized as follows:
SUMMER ROOM | 25% INCREASE IN THERMAL MASS | OCCUPANCY BASED ON THERMAL COMFORT EVENING
The space’s base winter occupancy of 14.2% (500mm brick envelope) shows a reduction to 12.1% at +25%, 9.2% at +50% and 6.0% at +75%.

REDUCTION IN THERMAL MASS The thermal analysis data for the summer room indicates that as a result of a reduction in the amount of thermal mass, the seasonal comfort based occupancy in the space shows an overall decline with significant drop at 75% reduction in thermal mass. The decline in thermal comfort is a result of larger fluctuations in indoor temperatures because of smaller amounts of thermal mass compared to the base case scenario. The thermal comfort and occupancy findings are illustrated in the graphs on the left and can be summarized as follows: SUMMER ROOM | 25% REDUCTION IN THERMAL MASS | OCCUPANCY BASED ON THERMAL COMFORT
The space’s base winter occupancy of 14.2% (500mm brick envelope) shows a slight increase to 15.3% at -25%, 14.4% at -50% and a slight reduction to 13.2% at -75%.

THERMAL MASS
THE EAST FACING ROOM
INCREASE IN THERMAL MASS The thermal analysis data for the east facing room indicates that as a result of an increase in the amount of thermal mass, the seasonal comfort based occupancy in the space shows insignificant changes throughout the year except during the winter in which a larger reduction in performance is observed. As a result, the space does not seem to benefit enough from the additional material and resources required for the increased thermal mass. The thermal comfort and occupancy findings are illustrated in the graphs on the left and can be summarized as follows: EAST FACING ROOM | 25% INCREASE IN THERMAL MASS | OCCUPANCY BASED ON THERMAL COMFORT
The space’s base winter occupancy of 18.9% (500mm brick envelope) shows a reduction to 17.6% at +25%, 15.8% at +50% and 13.2% at +75%.

THERMAL MASS
THE WINTER ROOM
INCREASE IN THERMAL MASS The thermal analysis data for the winter room indicates that as a result of an increase in the amount of thermal mass, the seasonal comfort based occupancy in the space is largely improved especially during the coldest months of the year in which a significant increase in performance is observed. The largest improvement is during winter occupancy and is specifically notable as it makes the winter room comfortable almost throughout the whole cold season. As a result of the improvements, the winter room’s occupancy practically covers the whole spring and fall seasons with minimal to no need for additional heating. The thermal comfort and occupancy findings are illustrated in the graphs on the left and can be summarized as follows:

REDUCTION IN THERMAL MASS The thermal analysis data for the winter room indicates that as a result of a reduction in the amount of thermal mass, the seasonal comfort based occupancy in the space shows an overall decline. In contrast to the other seasonal rooms, there is a large drop in winter occupancy even with 25% reduction in thermal mass; however, spring, summer and fall occupancy remain practically unchanged with a small reduction in thermal mass. The thermal comfort and occupancy findings are illustrated in the graphs on the left and can be summarized as follows: WINTER ROOM | 25% REDUCTION IN THERMAL MASS | OCCUPANCY BASED ON THERMAL COMFORT
The space’s base winter occupancy of 68.2% (500mm brick envelope) shows a considerable reduction to 59.2% at -25%, 48.0% at -50% and 41.6% at -75%.

THERMAL MASS
THE WEST FACING ROOM
INCREASE IN THERMAL MASS The thermal analysis data for the west facing room indicates that as a result of an increase in the amount of thermal mass, the seasonal comfort based occupancy in the space shows insignificant changes throughout the year except during the fall in which a slightly larger change in thermal performance is observed. Similar to the east facing room, the west facing room does not appear to benefit enough from the additional material and resources required for the increased thermal mass. The thermal comfort and occupancy findings are illustrated in the graphs on the left and can be summarized as follows:

THERMAL MASS THE BASEMENT
INCREASE IN THERMAL MASS The thermal analysis data for the basement indicates that as a result of an increase in the amount of thermal mass, the seasonal comfort based occupancy in the space is significantly improved. The largest increase in comfort based occupancy is during the summer making the basement practically comfortable throughout the whole season. At 75% increase in thermal mass, the basement is capable of providing adaptive comfort almost throughout the whole year. As a result, the basement appears to show the largest benefit in occupancy compared to the other rooms from the additional materials and resources required for an increase in thermal mass. The thermal comfort and occupancy findings are illustrated in the graphs on the left and can be summarized as follows:

REDUCTION IN THERMAL MASS The thermal analysis data for the basement indicates that as a result of a reduction in the amount of thermal mass, the seasonal comfort based occupancy in the space shows an overall significant decline with a reduction in thermal mass. The reduction in performance is visible even at a 25% reduction in thermal mass. At a 75% reduction in thermal mass, the basement becomes practically uncomfortable throughout the whole summer and shows a highly significant drop in spring occupancy. The thermal comfort and occupancy findings are illustrated in the graphs on the left and can be summarized as follows:

GLAZING RATIO
SECTION OVERVIEW In this section, we perform a sensitivity analysis based on incremental changes in the window to wall ratio for every seasonal room. The amount of glazing often has a direct impact on the amount of solar heat gains and internal heat losses which contribute to changes in indoor temperature ranges. As a design guideline, the results from the analysis can inform how aesthetic requirements or design limitations in terms of glazing percentage might affect the thermal performance of a seasonal room.

REDUCTION IN WINDOW TO WALL RATIO The thermal analysis data for the winter room indicates that through a reduction in the window to wall ratio, the comfort based occupancy in the space shows contrasting seasonal results. Winter occupancy sees a considerable decline from the reduced solar heat gains while summer occupancy sees a considerable improvement because of less overheating during the hot period. Overall, since winter occupancy is the main intention behind the thermal design of the winter room, a reduction in window to wall ratio would not be not beneficial to the thermal performance of the whole system.

INCREASE IN WINDOW TO WALL RATIO OF ABOVE GROUND SPACES The thermal analysis data for the basement indicates that as a result of an increase in the window to wall ratio of the above ground spaces, the seasonal comfort based occupancy has a considerable improvement during the summer. The increase in comfort is a result of the additional heat gains from the above ground spaces which makes the summer hours that previously felt too cold based on the adaptive comfort criteria, fall within the comfort criteria. Overall, the basement would benefit from an increase in glazing ratio of the above ground spaces. The thermal comfort and occupancy findings are illustrated in the graphs on the left and can be summarized as follows:

THERMAL INSULATION
SECTION OVERVIEW This section goes through an experimental analysis with thermally insulating materials that were not available during the time in which the central courtyard house was the prevailing housing typology in Central Iran. The experiments explore how the addition of insulation on the inside or the outside layer of the thermal mass changes the thermal behavior of each seasonal room compared to its original construction conditions. The aim of the insulation integration analysis is to understand the applicability of thermal properties of modern material in improving the performance of seasonal rooms. The findings can help guide a material optimization process that may lead to, for instance, a smaller amount of thermal mass required and thinner walls in exchange for minimal amounts of thermal insulation.

THERMAL INSULATION
THE SUMMER ROOM
THERMAL INSULATION ON EXPOSED EXTERIOR SURFACES The thermal analysis data for the summer room indicates that the addition of thermal insulation on its exposed exterior surfaces results in considerable improvements in the seasonal comfort based occupancy in the space especially during the summer and spring months. Interestingly, even the addition of a 25 mm EPS insulation on the outside layer of the thermal mass, increases the summer occupancy to practically the whole season. Overall, the summer room would largely benefit from the addition of thermal insulation on its exposed exterior surfaces. The thermal comfort and occupancy findings are illustrated in the graphs on the left and can be summarized as follows:

THERMAL INSULATION ON EXPOSED INTERIOR SURFACES The thermal analysis data for the summer room indicates that the addition of thermal insulation on its exposed interior surfaces results in considerable reduction in the comfort based occupancy in the space during the summer months. Since this change is negatively affecting the main seasonal occupancy (summer) for the space, the summer room would not benefit from the addition of thermal insulation on its exposed interior surfaces. The thermal comfort and occupancy findings are illustrated in the graphs on the left and can be summarized as follows:

THERMAL INSULATION
THE WINTER ROOM
THERMAL INSULATION ON EXPOSED EXTERIOR SURFACES The thermal analysis data for the winter room indicates that the addition of thermal insulation on its exposed exterior surfaces results in highly significant improvements in the seasonal comfort based occupancy over the course of the whole year. Interestingly, by adding enough insulation on the outside layer of the thermal mass, the reduced internal heat loss in the cold months and the reduced solar heat gain in the hot months can make the winter room thermally comfortable practically throughout the whole year. Overall, the winter room would largely benefit from the addition of thermal insulation on its exposed exterior surfaces. The thermal comfort and occupancy findings are illustrated in the graphs on the left and can be summarized as follows:

THERMAL INSULATION ON EXPOSED INTERIOR SURFACES The thermal analysis data for the basement indicates that the addition of thermal insulation on its exposed interior surfaces results in highly significant improvement making the basement the only seasonal room that is thermally comfortable for 100.0% of the year. Interestingly, the results are achievable even with the addition of the smallest amount of thermal insulation. Overall, the basement, in contrast to other seasonal rooms, would massively benefit from the addition of thermal insulation on its exposed interior surfaces. The thermal comfort and occupancy findings are illustrated in the graphs on the left and can be summarized as follows:

Comparing the indoor operative temperature ranges for all spaces to the outdoor air temperature ranges, it becomes evident that overall all seasonal rooms provide indoor environments that largely deviate away from the thermal stress present in the outdoor environment. This level of deviation, however, is dependent on the thermal and design characteristics of each room.

When comparing the lower temperature range of below 16°C, which often results in the need for heating, the outdoor percentage of 45.1% is reduced to 23.9% in the summer room, 24.3% in the east facing room, 1.9% in the winter room, 19.2% in the west facing room and 0.0% in the basement. The results indicate that while all rooms have an improved thermal condition compared to the outside environment, the winter room and the basement have the most optimum performance in reducing the number of hours that contribute to the need for heating. When comparing the upper temperature range of above 30°C, which often results in the need for cooling, the outdoor percentage of 14.8% is reduced to 4.7% in the summer room, 12.3% in the east facing room, 8.5% in the winter room, 13.2% in the west facing room and 0.0% in the basement. Accordingly, the summer room and the basement have the most optimum performance in reducing the number of hours that contribute to the need for cooling.

winter room has the highest percentage winter occupancy. However, among all seasonal spaces, the basement has the highest percentage of winter occupancy. Considering spring occupancy, with the summer room at 79.0%, the east facing room at 85.5%, the winter room at 95.2%, the west facing room at 83.7% and the basement at 86.7%, we observe that among all seasonal spaces, above and below ground, the winter room has the highest percentage of spring occupancy. In terms of summer occupancy, with the summer room at 89.5%, the east facing room at 55.2%, the winter room at 69.0%, the west facing room at 55.3% and the basement at 43.7%, we realize that among all seasonal spaces, above and below ground, the summer room has the highest percentage of summer occupancy. For fall occupancy, with the summer room at 63.2%, the east facing room at 66.3%, the winter room at 97.9%, the west facing room at 71.8% and the basement at 100.0%, we realize that among the above ground spaces, the winter room has the highest fall occupancy. However, among all seasonal spaces, the basement has the highest percentage of fall occupancy.

The product of the developed methodology that takes into account a thermal-comfort-based migration pattern in the central courtyard house together with thermal and comfort data for all seasonal rooms is the whole system comfort-based occupancy map shown at the top left. Using the chart, we can test out the original thesis question of whether the central courtyard house as a whole system can provide annual thermal comfort. As observed in the graph, the system, as a whole, provides thermal comfort for 98.9% of the year practically covering

every hour of the year. As discussed before, to reach this percentage occupants follow a micro-migratory pattern to the most thermally comfortable spaces within the house. Overall, for 98.9% of the year, occupants have access to at least one thermally comfortable space with no need for heating or cooling. Additionally, for 38.9% of the year all seasonal spaces are comfortable at the same time giving the occupants the choice to choose which space to occupy. For only 1.1%, all seasonal spaces fail to provide thermally comfortable conditions. In order to understand the impact of a design deviation from the base characteristics of the central courtyard house typology, a series of sensitivity analyses were performed. These analyses respond to common design requirements or limitations that result in changes in building orientation such as a different urban grid layout, variations in the amount of thermal mass such as changes in wall thickness and variations in the percentage of windows to wall ratio such as aesthetic requirements. In addition to the traditional characteristics, the changes in performance and thermal behavior based on the addition of thermal insulation to the exposed exterior/interior surfaces were also analyzed. The observations indicate that seasonal rooms very often have different thermal responses to the same change. As a result, resources should be appropriately distributed to the appropriate room based on specific thermal design requirements. For instance, while the summer room benefits from the addition of thermal insulation on the exposed exterior surfaces, the same design modification does not have the same impact on the basement and in contrast, the basement benefits from the

addition of insulation on exposed interior surfaces. In order to provide a framework for future housing design projects that aim to provide annual thermal comfort based on the methodology introduced in this research, the results from the thermal sensitivity analyses are summarized into simple charts that illustrate the effect of a specific design change or deviation on the thermal behavior and seasonal occupancy of each seasonal space. The framework can guide a designer to put emphasis on appropriate design changes that respond to the local climate and thermal needs of the building. In a cold climate, the emphasis would be on winter occupancy while in a hot climate summer occupancy plays a more crucial role. In moderate climates with all four seasons, all seasonal rooms might have the same weigh. To reach an optimal thermal solution, the design of a building should first be analyzed through the proposed methodology as a base case that provides thermal data for each seasonal room. Next, the designer would go through an optimization process based on the framework provided here to create the maximum thermal comfort possible through the least amount of resources required. The results for the whole system could then be tested against the thermal and comfort requirements. As originally hypothesized, the results from this research indicate that if analyzed and understood appropriately, the central courtyard house and its network of seasonal rooms can provide year-round thermal comfort, through only passive means, in climates where majority of outdoor hours are uncomfortable. This requires the inhabitants of the building to follow a comfort-based

migratory pattern and occupy to different spaces within the house based on daily or seasonal climate variations. The base case study indicates that for a considerable percentage of the year all seasonal spaces are comfortable at the same time giving the inhabitants the option to choose any space within the house. The sensitivity analyses indicate that this percentage could be increased through an thermal design optimization process that minimizes the need for moving from one space into another.
