“…Mokslinėje literatūroje akcentuojama, kad, be energinio efektyvumo, pastatų modernizavimas turi įtakos pastato fizinės būklės atnaujinimui, patalpų mikroklimatui (Martinaitis, Kazakevičius ir Vitkauskas, 2007;Hamid et al, 2018). Tačiau šių kriterijų naudos įvertinimas sudėtingas ir reikalauja nuolatinės esamos padėties stebėsenos.…”

The purpose of the study was to analyse the thermal characteristics of the microclimate parameters and envelope of the renovated 12 residential multi-storey buildings by assessing their impact on heat savings. The relevance of this work is related to a significant discrepancy between the theoretically simulated / estimated heat savings after the renovation and the actual measured values of heat meters. After the statistical analysis of the accumulated data, the average indoor temperature of the premises, relative humidity, and CO2 concentration were determined, and the distribution of frequency was assessed. The heat transfer coefficients of the walls, window glasses and window frames, measured according to the manufacturer’s recommended methodology, are reviewed in this work. The results are compared with the current requirements for microclimate. The results revealed that in the investigated buildings after the renovation the weighted average temperature of the premises was higher than the temperature under standard conditions, but the air quality (CO2 concentration) was insufficient. The air quality improvement measures increase heat demand and reduce the expected heat savings. Santrauka Tyrimo tikslas buvo atlikti modernizuotų 12 daugiabučių namų mikroklimato rodiklių ir atitvarų šiluminių charakteristikų analizę įvertinant jų įtaką sutaupytam šilumos kiekiui. Darbo aktualumas susijęs su pastebimu neatitikimu tarp teoriškai sumodeliuoto ar apskaičiuoto sutaupyto šilumos kiekio po modernizavimo ir faktinių užfiksuotų skaitiklių reikšmių. Darbe atlikus sukauptų duomenų statistinę analizę buvo nustatyta vidutinė patalpų vidaus temperatūra, santykinis drėgnis, CO2 koncentracija bei įvertintas reikšmių pasiskirstymo dažnis. Aptarti pagal gamintojų rekomenduojamą metodiką matuotų sienų, lango paketo ir lango rėmo šilumos perdavimo koeficientai. Gauti rezultatai palyginti su šiuo metu galiojančiais mikroklimatui keliamais reikalavimais. Rezultatai atskleidė, kad tirtuose pastatuose po modernizavimo patalpų svorinė vidutinė temperatūra buvo aukštesnė nei norminė, tačiau oro kokybė yra nepakankama. Oro kokybės gerinimo priemonės didina šilumos poreikį ir mažina tikėtiną sutaupytos šilumos kiekį.

“…Such intentions complied with the increased efforts of scientists towards improvements in the thermal performance of building envelopes. In this sense, many research studies aimed at the investigation of thermal insulation walls, heat transfer in porous building materials, application of different material layers including insulation materials, or utilization of various admixtures including phase change materials were carried out on this account [2][3][4][5][6][7][8][9][10][11][12][13][14][15].…”

Functional Properties of SAP-Based Humidity Control Plasters

et al. 2021

The application of materials with high moisture storage capacity close to the interior surface presents a prospective passive method for improving indoor relative humidity conditions. In this paper, lime-cement plasters containing three different types of superabsorbent polymers (SAPs) in varying dosages are introduced and their mechanical, hygric, and thermal characteristics are analyzed in a relation to microstructure. The experimental results show a significant effect of both SAP amount and chemical composition on all functional properties of studied plasters. The incorporation of 1.5% of SAP may induce up to 2.5 better moisture buffering, thus significantly improving the passive humidity control capability. Considering overall functional parameters of SAP-modified plasters, the dosage of 1 wt.% can thus be viewed as a rational compromise between the moisture storage capability and mechanical properties. The obtained wide sets of parameters can be utilized directly as input data of computational models suitable for the assessment of the interior microclimate of residential and administrative buildings.

“…Most previous research on housing renovation focuses on technical and economic aspects, in particular related to energy efficiency (Abdul Hamid et al 2018), whereas more socio-political studies on renovation often concern macro patterns of displacement and gentrification (e.g. Baeten et al 2017).…”

Tenant Voice – As Strong as It Gets. Exit, Voice and Loyalty in Housing Renovation

This article applies Hirschman's model of exit, voice and loyalty to a Swedish case of housing renovation in a building with comparatively well-off tenants. Hirschman's framework is particularly well suited for understanding the housing market with its heterogeneity and high transaction and attachment costs, and accordingly strong loyalty and voice. Our study indicates that the exit-voice-loyalty framework is a useful tool for analysing renovation processes, since these trigger both voice and exit behaviour. We argue that renovations can be considered as critical junctures to an existing tenant-landlord relation, thereby exposing power relations on the housing market. In the case studied, tenants were not able to affect the scope of the renovation directly, but tenant voice did affect the process as well as the outcome in other respects. The capable tenant group makes this a "most likely case" for testing the limits of tenant influence in housing renovation processes.
