Dwelling, which is a basic human need (Maslow, 1970) should act as an object of technology that serves as a place for individuals or families to conduct all their daily activities in order to meet their needs in life. In case of sustainability, thermal comfort is one of the most important comfort conditions that must be achieved (Szokolay SV, 1980). Proper air movement control may lessen the demand for energy, thus reducing the expense of providing a comfortable home (Boutet, 1987). However, to ensure the acceleration of air movement, the availability of both inlet and outlet openings in the building or space become an absolute requirement (Olgyay Victor, 1973). Rusunawa is a typical rental-apartment in Indonesia that served for low income families. The types of existing space generally include: a multi-functional space, a kitchen, and a bathroom/WC, and sometimes is furnished by a balcony. There is only one living space in rusunawa that is the multi-functional space which is often used for: living, sleeping, studying, watching TV, eating, storing, child-caring, and probably more other functions. Not to mention if the family has a home-based business. Among rusunawa unit types that existed in all fourteen locations in Surabaya, some of them were built without a really outdoor balcony, meaning that the balconies were provided indoor, instead of in the cantilever system. These indoor balconies accommodate the same household activities as those of outdoor balconies. However, the contribution to the internal thermal comfort may not be the same. By using Ecotect analysis 2011 program, This research intends to investigate the comparison of thermal conditions of the inner space between rusunawa unit having a balcony (outdoor), and rusunawa unit without a balcony (indoor). The result of this comparison is meant to convince the contribution of unit having a balcony to the thermal comfort of inner space, to ensure whether the design of the future rusunawa units should be equipped with a balcony or not. To further reassure its contribution, this experiment is continued by comparing between unit having just a balcony and unit having a balcony that equipped with sun-devices.

This paper presents the results of “Upgrade and Save”, a program to upgrade the standard electric furnaces and air-conditioning units in Mobile Homes for energy-efficient heat pumps. This program is implemented in North Carolina, USA and pays about $700 through a rebate provided by the North Carolina State Energy Office to the Mobile Homes' owners. The goal of this project is to subsidize low-income families by lowering their heating cost in the winter as well as improving their homes' indoor thermal comfort. More than 300 mobile homes have participated in this program. Field measurements, meter readings of the actual electrical consumption, and annual building energy simulation were used to measure the dollar saving and the indoor thermal comfort improvement in the mobile homes after the heating system upgrade. This research proved that the dollar saving of using the heat pump for heating in mobile homes ranges from $51 to $128 annually.

Home-based asthma environmental education for parents of asthmatic children is needed since many health professionals lack the time to offer it. However, developing targeted and tailored education is important in order to address the individual needs of participants. This nonrandomized longitudinal study examined knowledge on asthma with an Asthma and Healthy Homes educational intervention training offered to parents of children from low income families who reside in the Rio Grande Valley of Texas. Eighty-nine parents received the training and pre- and posttest surveys were used to measure knowledge outcomes. A standardized assessment on asthma triggers was used to identify the different triggers each child was exposed to, and a follow-up survey was conducted 6 months after the educational intervention to identify how many parents reported household and behavior changes as a result of the training. Results showed significant changes in behavior by participants as a result of the training received. This study suggests that these behavioral changes are attributed to the dual “targeted” and “tailored” educational interventions delivered to parents which resulted in a greater understanding of how to manage asthma by eliminating asthma triggers in their respective homes.

Comfort Condition

People tend to maintain symmetry between comfort and economy while choosing essential commodities needed in their life. Families buy a house which may offer comfort condition, but at minimum in term expenses of energy throughout a life. Thus, it is most important to erect a house to provide comfortable condition and moderate the lifetime expenditure by saving energy consumption. Sensation of thermal comfort varies from people to people, even in an identical environment. To minimize the consumption of energy of building, cost of consumed energy and to provide a comfortable house, thermal comfort analysis in indoor environments have attracted many researchers. Fanger’s Predicted Mean Vote (PMV) - Predicted Percentage of Dissatisfied (PPD) model is widely accepted theory for assessment of building indoor thermal conditions. In the present work, thermal comfort of an LIG house in Chhattisgarh region of India has been analyzed based on PMV-PPD method for months representing three different seasons in a year i.e. May, September and December representing summer, post monsoon and winter respectively. Cooling, heating and actual energy load of LIG house has been calculated and reported for the above mentioned months. From analysis it is concluded that inhabitants are comfortable only during the winter.

Abstract The most direct causes of malnutrition are food consumption and infection. Yet the prolonged Covid-19 pandemic has limited low-income families’ ability to fulfil the need for nutrition consumption, particularly for children under five. Responding to this situation, we sought to develop home-based ready-to-use supplementary foods (RUSF-HB) from local ingredients that are energy-protein-dense, affordable, simple and easy to produce at home. We created three milk-free formulas (MFFs) and six standard formulas (STFs). Three cheap and abundant local foods: soybeans, cowpeas, and mung beans were combined with rice flour, refined sugar, and coconut oil. A cross-over study design was used to assess food organoleptic, which showed that the products were comparable in several sensory aspects except for the odour and the taste. Soybeans-based formulas contain slightly more energy and protein compared to mung beans or cowpeas-based ones. However, the mung beans-based formulas were more favourable to caregivers and children, particularly their taste and smell. The products contain slightly less energy than the recommended ones but high enough to supply macronutrient for those in need on a regular basis. The caregivers considered the total price for the products was affordable, and the formula was easy to follow.

Low Income Families

This study describes the implementation of a nurse home visiting asthma education program for low-income African American families of young children with asthma. Of 55 families, 71% completed the program consisting of eight lessons. The achievement of learning objectives was predicted by caregiver factors, such as education, presence of father or surrogate father in the household, and safety of the neighborhood, but not by child factors, such as age or severity of asthma as implied by the prescribed asthmamedication regimen. Incompatibility between the scheduling needs of the families and the nurse home visitors was a major obstacle in delivering the program on time, despite the flexibility of the nurse home visitors. The authors suggest that future home-based asthma education programs contain a more limited number of home visits but add telephone follow-ups and address the broader needs of low-income families that most likely function as barriers to program success.

Abstract- Indonesia with the characteristics of tropical climate requires control in design to achieve thermal comfort both in outside space and inside space. One of the factors that can affect thermal comfort is the pattern of air movement and air velocity. Landmark Residence Apartment is one of the new apartments in Bandung, with mass ‘U’ form in line up of new partially awakened. The newly constructed 'U' mass formation forms the characteristic of the two different masses, the space side in the closed A mass with the characteristic of the centered space as well as the side in the open mass B. this apartment become an object of research to determine the factors of order and mass form to the characteristics of air movement as well as thermal comfort in the outside space as a space of activities in residents. The method used in this research is descriptive-quantitative with simulation software Flow Design to know the air movement and measurement of thermal comfort factor at the point of population and sample which have been determined. This thermal factor will be analyzed using CET Nomogram method, so it generates thermal comfort level in outer space which will be associated with order and mass form of apartment. By using analysis of air movement patterns and CET Nomogram, it is seen that thermal comfort level in the outside space Landmark Residence apartment is more affected by wind velocity. The mass 'U' form with the back to wind direction will produce high wind velocity on the outside space of the building's side, while on the inner side of the 'U' form will form the shadow of the wind and the pattern of turbulence air movement affecting the achievement of different thermal conditions. The 'U' mass sequence lined up can also cause air movement on the inner side of closed A mass not getting enough air movement compared to open mass B with better airflow pattern. The pattern of air movement on the inner side of mass A can be at any time higher when the wind velocity enters the gap between the masses.  Key Words: apartment, outside space, mass ‘U’ form in line up, air movement, thermal comfort.

 This paper investigates the present situation of thermal comfort in typical low-income houses located in Betong and Saratok, Sarawak, Malaysia. Investigations were carried out by measuring airflow rate, temperature, relative humidity and mean radiant temperature at specific points in one chosen house of each district. Different low-income housing estates were chosen for comparisons due to the different location and position of each house. Although both of these low- income houses have similarity in design but differs in layout arrangement. Results are presented and analyzed using Corrected Effective Temperature (CET) index in two different window and door opening configurations. The results show that the modern low-income house is thermally uncomfortable under certain conditions. High internal air temperatures occurred when doors and windows were closed combined with low air velocity contributes to thermally uncomfortable environment. Once all doors and windows were opened, allowing the air movement to increase, thermal comfort was achieved although air temperatures remained high.

The South African Highveld is a portion on the inland plateau characterized by low winter ambient temperatures. Studies done in several climatic regions around the world have found a positive relationship between inadequate housing and low indoor temperatures during the winter season. Prolonged exposure to low indoor temperature is a threat to human physical health. This study characterizes indoor human thermal comfort conditions in typical low-income residential dwellings during the winter season. Mapping indoor human thermal comfort can assist in exploring the potential for domestic thermal insulation retrofits interventions. In-situ temperature measurements were done in 2014, 2016 and 2017 across three Highveld settlements of kwaZamokuhle, kwaDela, and Jouberton. The sample included a mixture of old (pre-1994), post 1994 Reconstruction and Development Programme (RDP) as well as non-RDP structures. Findings were that 88% of sampled dwellings in Jouberton 2016, 86% in Jouberton 2017, 62% in kwaDela and 58% in kwaZamokuhle had daily mean temperatures below the WHO guideline of 18°C. These low indoor temperatures indicate poor insulation in these sampled dwellings. Across all settlements, insulated dwellings had higher daily mean indoor temperatures than non-insulated dwellings. These findings indicate the potential to use thermal insulation retrofits in improving indoor thermal conditions as the majority of dwellings are non-insulated thereby exposing occupants to low indoor temperatures.
