Dynamic daylight simulations: Impact of weather file’s choice
2015
Abstract This paper is the second step of a research project aimed at investigating the impact of the use of different weather data files on daylight simulations’ results. Simulations were carried out for a simple standalone office using three weather files (IWEC, Meteonorm and Satel-Light) for two European locations (Copenhagen and Rome); moreover the office’s exposure was changed according to the four main orientations (North, East, South and West). Results were analyzed both in terms of Annual and Monthly Light Exposures, dynamic daylight performance metrics (DA, DAcon, UDI) and sunlight’s incidence. It was demonstrated that differences between the results obtained with the different wea…
Decoupling Office Energy Efficiency From Employees' Well-Being and Performance: A Systematic Review
2019
Energy efficiency (i.e., the ratio of output of performance to input of energy) in office buildings can reduce energy costs and CO2 emissions, but there are barriers to widespread adoption of energy efficient solutions in offices because they are often perceived as a potential threat to perceived comfort, well-being, and performance of office users. However, the links between offices' energy efficiency and users' performance and well-being through their moderators are neither necessary nor empirically confirmed. The purpose of this study is to carry out a systematic review to identify the existing empirical evidence regarding the relationships between energy-efficient solutions in sustainab…
Iekštelpu vides kvalitātes novērtējums pirmsskolas un skolas vecuma bērnu izglītības iestādēs
2017
Bakalaura darba “Iekštelpu vides kvalitātes novērtējums pirmsskolas un skolas vecuma bērnu izglītības iestādēs” ietvaros veikts iekštelpu mikroklimata un piesārņojuma līmeņa novērtējums trīs izglītības iestādēs (PII Rīgas Valdorfskolas bērnudārzs, Rīgas Valdorfskolā un Rīgas 49. vidusskolā) laika posmā no 2016. gada rudens līdz 2017. gada pavasarim. Novērtēšana veikta izmantojot tiešo mērījumu metodi, atsevišķu parametru atbilstība vērtēta salīdzinājumā ar noteiktajiem normatīvajiem lielumiem, savukārt citi, kuriem normatīvu nav, salīdzināti ar Pasaules veselības organizācijas vadlīnijās iekļautajiem lielumiem.
Students' school‐level symptoms mediate the relationship between a school's observed moisture problems and students’ subjective perceptions of indoor…
2020
Moisture damage can influence the subjective assessment of indoor air quality (subjective IAQ) in various ways. We studied whether the frequency of symptoms reported across students at school level mediates the relationship between observed mold and dampness in a school building and students' subjective IAQ. To answer this research question, we tested a multilevel path model. The analyzed data were created by merging two nationwide data sets: (a) survey data from students, including information on subjective IAQ (N = 24,786 students); (b) data from schools, including information on mold and dampness in a school building (N = 222). After the background variables were adjusted, schools' obser…

Historic additional stories in the cultural heritage of Palermo: critical analysis for the purpose of structural and energy improvement
2018
This paper analyses construction features and performances of additional storeys in historic buildings. The recurring characteristics of these historic accretions are investigated by focusing on the cultural heritage of Palermo, where the practice of extending buildings by raising new levels was widespread both in monumental and vernacular architecture, in public and private constructions. The performance deficiencies of additional storeys are examined in terms of structural safety, thermal comfort and building energy demand. On this basis, the utility of mapping these structures, their morphology and their location in the urban fabric is discussed.
Dampness and student-reported social climate: two multilevel mediation models.
2021
Background Little previous research has analysed the relationship between schools' indoor air problems and schools' social climate. In this study, we analysed a) whether observed mould and dampness in a school building relates to students' perceptions of school climate (i.e. teacher-student relationships and class spirit) and b) whether reported subjective indoor air quality (IAQ) at the school level mediates this relationship. Methods The data analysed was created by merging two nationwide data sets: survey data from students, including information on subjective IAQ (N = 25,101 students), and data from schools, including information on mould and dampness in school buildings (N = 222). The …
Creating Office Spaces in the Mediterranean. The importance of well-being, health and performance of office users
2018
Recent research has studied the influence of office buildings indoor environment quality (IEQ) on employees’ well-being, health and performance. However, it seems that it has not been explicitly explored what are the appropriate environmental conditions to different work patterns that coexist in these spaces. This paper presents results of an empirical research, based on the synchronized measurements of different IEQ parameters (i.e., noise, lighting and temperature), and well-being, health and performance of 71 employees in twelve office spaces in the Valencian Community along three periods, considering winter and summer conditions. Findings of the first winter period data, suggest the exi…
