People's subjective response to any thermal environment is commonly investigated by using rating scales describing the degree of sensation, comfort, and acceptability. Subsequent analyses results collected in this way rely on assumption that specific distances between verbal anchors placed scale exist relationships from different dimensions are assessed (e.g. sensation comfort) do not change. Another inherent such independent context which they used (climate zone, season, etc.). Despite...
Metallic nanoparticles are used to improve solar cell efficiency due plasmon mediated photo-voltaic effect. We present various channels of this phenomenon in semiconductor cells with p−n junction and chemical-type exciton photovoltaic mechanism. Besides previously known by strengthening sun light absorption metalized we have described the influence plasmonic onto internal electricity cells. The latter case analyze on example hybridized perovskite regarded as most promising III-rd generation....
Abstract Thermal discomfort is one of the main triggers for occupants’ interactions with components built environment such as adjustments thermostats and/or opening windows and strongly related to energy use in buildings. Understanding causes thermal (dis-)comfort crucial design operation any type building. The assessment human perception through rating scales, example post-occupancy studies, has been applied several decades; however, long-existing assumptions these scales had questioned by...
The residential sector of existing buildings has great potential in energy savings and the improvement indoor conditions. modernization is particular concern to policies European Union, local governments, building users. aim this paper present an analysis parameters consumption for heating apartment located a pre-war tenement before after thermomodernization. was conducted winter conditions based on measurements simulations. Originally, had not undergone any thermomodernization actions since...
Naturally ventilated buildings especially dedicated for educational purposes need to be design achieve required level of thermal comfort and indoor air quality. It is crucial in terms both: health productivity the room users. Higher requirements environment are important due students concentration, their ability acquire new knowledge willingness interact with lecturer. The article presents results experimental study surveys undertaken naturally lecture room. data analysed CO2 concentration...
Of all the European Union's member states, Poland has most acute ambient air pollution problem. An urgent transition from solid-fuel heating (<em>e.g.</em> coal and wood) in housing sector is required to improve quality country. National regulations still allow sale of solid fuels for heating, but some municipalities impose local resolutions with binding deadlines bans. A real-world study covering 422 apartments heritage tenements Wrocław presented. link between domestic usage tenure type...
Energy and economic assessments are of great relevance in the context decision processes for most optimal solutions building renovations. Following method recommended by UNIDO, analyses thermal modernization options carried out based on Simple Payback Time (SPBT), Net Present Value Ratio (NPVR) Internal Rate Return (IRR) indices. Incorporating these indicators a new approach that involves aggregating thermomodernization activities not only cold warm seasons separately, but throughout whole...
Research towards understanding the relationship between maintaining thermal comfort and energy efficiency in public utility buildings was undertaken among 323 1st year students during class hours. Questionnaires surveys measurements of indoor conditions were performed. The article identified students’ sensations perceptions concerning conditions. Temperature, relative humidity, air velocity CO2 concentration measured to assess room showed that auditorium had almost comfortable according...
Water consumption in hall buildings is substantial and characterised by variability over the time: yearly, seasonality, monthly, weekly, daily, hourly second. Both, water their irregularity, influence on many processes technical issues. Purposes for which consumed are various. Beyond technological processes, one of most water-intensive demand need hygienic sanitary purposes, especially production with high degree soiling work. The paper presents study hot (DHW) its profile purposes two...
It is well known that people spend about 90% of their lifetime in buildings where the indoor environment strongly influences health and productivity. Therefore it crucial to maintain proper internal conditions, thus ensure comfort for building users. Due nature complexity thermal difficult describe with physical parameters. However there a number available methods assess conditions define level - from simplified based on measurement basic parameters complex approach – use computational fluid...
People living in urban areas are exposed to a number of threats related with dense tissue and high vehicles. These include air pollutions, traffic noise temperatures. In addition, large cities struggling energy consumption for heating cooling purposes. One the possibilities reduce mentioned undesirable effects is use vegetation on walls. Plants absorbs pollutants air, produced oxygen, mounted external walls create thermal insulation positively affect psychological aspect. Green can be used...
The proper level of comfort conditions is one the main goal when designing HVAC systems in buildings. It influences our self-being, health and productivity. Thermal a complex issue relates to indoor air parameters personal factors. publication presents outcome research undertaken lecture room at Wroclaw University Science Technology, Poland. consisted measurements parameters, questionnaire survey PMV PPD calculations based on different approaches.
Abstract In winter thermally inefficient building envelopes of pre-retrofit historical housing allow for ca. sevenfold higher heat loss from heated apartments than the new built in Poland. As a result space heating tenements is regarded to be highly energy demanding and costly if internal temperatures were kept on average at standard 20 °C assumed regulations. this field study, carried out January-March 2020, we investigated circadian thermal profiles associated comfort both pre-and...
Stand-alone buildings operated periodically require heat supply for hot water and heating purposes to be carefully analyzed in terms of the technical capabilities, energy financial outlays. The paper presents analysis central stand-alone cloakroom building located Poland. is undertaken different variants delivery a from electric heaters, gas boiler district solutions renewable sources applications, namely solar panels pumps. For each solution, usage usable, final primary was calculated. Also...
The energy consumption for space heating and domestic hot water preparation are significant burdens of a polish household budget, especially in old tenement houses. Simultaneously, lowering the emission pollutants is under great importance one main goals to achieve big cities. This policy results need elimination systems based on solid fuels. article analyses environmental social consequences exchange heat sources such buildings quarters Wroclaw. It presents how this change will affect...
The revitalization of historical buildings is a subject that increasingly being discussed around the world. This connected with goal set by European and thus Polish local policy to reduce energy consumption in existing buildings. publication presents an unconventional solution for thermal modernization utilization green walls. article literature legal acts review on walls, their construction impact It describes benefits disadvantages resulting from use vegetation external Additionally...
