This paper provides a review of research that addresses the relationship between indoor temperatures and health outcomes, taking into consideration studies that focus heat or cold exposure within the household context. It aims to extend previous research by considering both indoor temperatures from existing housing, and empirical studies that focus on energy efficiency measures and subsequent health impacts. To achieve this aim, a literature review was undertaken, combining engineering and health databases. The review established that, overall, inadequate indoor temperatures are associated with poor health status, whereas energy efficiency measures have been associated to improved indoor temperatures and occupant’s health namely regarding cardiovascular, respiratory and mental health disorders. These health conditions are among the most prevalent non-communicable diseases (NCD). The review also highlighted the need for more empirical studies with an extended timeframe to deal with climate change challenges. It underlined the potential advantages of the convergence between health and energy efficiency studies, for better modelling and planning.

“…In terms of lighting systems, because of their instantaneous system response, the development and implementation of occupancy-based control have been relatively straightforward. As a result, various building standards and green building rating programs have requested or recommended occupancy-based lighting control [30]. Literature has reported that the energy-saving potential of using occupancy information ranges from 20 to 75% [31][32][33][34].…”

“…A 1999 research from Bond et al [47] correlates thermal and lighting comfort level with energy consumption. Two decades later, the excellent review of Jung e Jazizadeh [48] includes the relevant role of users in occupancy and comfort with relation to building energy efficiency. The work of Krokas et al [49] proposes an algorithm to correlate the cumulative energy costs with the thermal comfort score (in PPD, Predicted Percentage of Dissatisfied) in order to optimize building energy management system.…”

“…The survey was prepared following standards ISO 10551 [57]. Several studies adopt the subjecting approach by submitting surveys [48][49][50][51][52][53][54][55][56][57][58][59][60][61][62]. Sometimes, particular conditions or particular users, such as children in a 4-5 years age range [15,63], require the survey to be integrated or adapted to facilitate the understanding and the filling procedure.…”

Indoor Thermal Comfort of Pregnant Women in Hospital: A Case Study Evidence

Despite studies on thermal comfort being consolidated in the scientific literature, people’s well-being in some specific conditions and places, such as hospitals, requires to be further explored. The paper describes the methodological approach adopted to evaluate thermal comfort level and perception of pregnant women hosted in the obstetric ward of a test-bed case (Sant’Orsola hospital in Bologna, Italy). The methodology adopts a mixed approach that compares the results of on-site monitoring by probe (as quantitative data) with the ones of a survey (questionnaire form) delivered to the involved subjects (as qualitative data) to understand if metabolic alteration may influence the pregnant women’s perception of comfort conditions. The first follows ISO 7730, the second, ISO 10551. The comparison between the instrumental collected data and the outcomes of the survey revealed a wide gap between TSV (Thermal Sensation Vote) and PMVm (Predicted Mean Vote, measured on-site). The reason can be identified in the use of a standardized metabolic unit from ISO that does not correctly reflect the physiologic condition of pregnant women. Following a trial and error methodology, a met value for pregnant women is accordingly proposed. Moreover, an adaptive thermal comfort approach is adopted. This research is a first step towards the definition of specific thermal comfort in a hospital ward hosting pregnant women and more generally offers a reflection about the need to define specific met in the standards for some particular categories (children, elderly, pregnant women, etc.) when investigating thermal comfort.
