Many serious illnesses are linked to everyday exposures to toxic chemicals. In the U.S., most chemical exposure comes from common consumer products such as pesticides, fragranced products, cleaning supplies, and building materials--products so widely used that people consider them "safe." As the links between everyday toxic exposures and potential health effects become better understood, evidence increasingly shows that reducing exposures can create a healthier society. Although some individuals may choose to build a healthy home and maintain a healthy household, they are still exposed to pollutants at their residences from the actions of others, such as to pesticides that are used by neighbors, businesses, and governments. They need healthy residential developments in environmentally healthy communities. This research investigates "healthy residential developments," defined as a property that aims to reduce pollutant exposures to the extent required by vulnerable populations, which for this research are individuals with multiple chemical sensitivities (MCS). Through a case study approach, this research investigates two exemplars of healthy residential developments, and explains how and why they form and continue. It also examines their implementation methods, and implications for planning and policy. Primary data collection methods included in-person interviews, telephone interviews, and site visits. Research strategies included the analysis of interview data, and categorical aggregation using thematic categories within and across cases. The categories focused on factors of formation and continuation for the two healthy residential developments. Findings include the challenges of people disabled with MCS to find safe housing; the importance of planning to address these challenges; the role of individuals, funding, and zoning in the formation of healthy residential developments; the role of funding, safe maintenance, and property management in their continuation; and, the need for affordable and safe housing for vulnerable populations. Future research can address the need to develop methods to create and sustain healthy residential developments, understand and reduce sources of exposure that initiate and trigger chemical sensitivity, and investigate experiences and implementation strategies in other countries.

This diploma thesis is focused on nearly zero energy buildings, which are a mandatory part of construction of the buildings in Czech republic after 2020. It also deals with HVAC and its design as part of these buildings. The theoretical part deals with legal and technical regulations and possible savings in HVAC systems. The computational part is focused on two solution of HVAC systems in given object. The project part is about the given object, which is otevřená zahrada Brno. This building was founded by Nadace Partnerství s.r.o.. This third part of diploma thesis deals with the quality of indoor microclimate and evaluation of the heat recovery system effiency, which is applied in local HVAC unit.

This project investigated the sustainability of homes within three intentional communities. Semi-structured interview and photographic walkthroughs examined the variability of architectural and technological approaches toward sustainability. These include: passive solar design, green roofs, radiant flooring, composting toilets, ground assist heat pumps, solar water heaters, multiamily units and modular construction. It was hypothesized that variation in sustainable construction is related to socioeconomic status and that economics would be a constraint. This project investigated whether communities were transmitting their practices to wider society, if individuals were copying vernacular architecture and if architectural practices followed individual beliefs regarding sustainability. It was found that the Internet is the main method of conveying these practices; that variability was tied less to individual beliefs than to the communities’ institutional documents; and that copying vernacular architecture was for aesthetics not sustainability. Intentional communities are good models for sustainable development, but knowledge transmission is limited.

The subject of this graduation thesis is a conceptual architectural study of the former house of correction extension, annex and reconstruction and also a new ideological solution of adjacent areas and total building plan . The house is located in the Brno’s Bronx district. The reconstruction is focused on the use of alternative housing concepts with the general target at the whole city quarter reneration – address change.
