1. 1. Ventilation for reduced indoor spread of Covid 19 and similar diseases : A literature review focusing on hospital environments

   University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

   Author : Cyrus Ourak Pour; [2023]
   Keywords : COVID-19; SARS-CoV-2; Ventilation system; Mixing ventilation MV ; Displacement ventilation DV ; Under floor air distribution UFAD ; Ultraviolet light UV ; HEPA filter; COVID-19; SARS-CoV-2; Ventilationssystem; Blandningsventilation; Deplacementventilation; Luftfördelning under golv; Ultraviolett ljus; HEPA-filter;

   Abstract : Today, a significant portion of individuals’ time is spent indoors, estimated at approximately 90% of their total time. This raises concerns about the transmission of Coronavirus Disease 2019 (COVID-19) instigating Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and similar viruses and highlights the critical role of ventilation systems in indoor environments, which this study aims to investigate.

3. 2. Investigation of different ventilation profiles to avoid stratification in Nearly Zero Energy Buildings

   University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

   Author : Alazne Irene Varela Santana; [2023]
   Keywords : stratification; water model; comfort; mixing; temperature; potential energy; net zero energy building;

   Abstract : This research paper examines possible solutions for the problems that warm air heating is suffering in Nearly Zero Energy Buildings. These NZEBs are passive houses constructed to have high energy efficiency where the quantity of power used is equal to the power created annually, produced locally or in the surroundings by renewable energy sources.

4. 3. Ventilation systems in Low Energy Houses: augmentation of mixing in a small-scale water model by generating resonance

   University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

   Author : Borja Chocarro de Erauso; [2022]
   Keywords : Stratification; buoyancy frequency; resonance; mixing; passive house; water model;

   Abstract : Some passive houses are provided a warm supply flow inlet coming from a mechanical ventilation system, creating issues of shortcut ventilation as a result of an originated density layer stratification, since the supplied warm air is confined to the ceiling level. In this way, there exist several complaints of thermal discomfort and poor indoor environmental quality in passive houses. READ MORE

5. 4. Experimental investigation of ventilation performance of corner placed stratum ventilation in an office environment

   University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

   Author : Gasper Choonya; [2019]
   Keywords : Stratum ventilation; local air change index; air change efficiency; ventilation effectiveness; draught rate; percentage dissatisfied; heat removal effectiveness;

   Abstract : Energy use in buildings account for about one third of the total global energy supply and contributes as much as 30% of the anthropogenic greenhouse gas emissions. It is estimated that energy use in buildings will increase to 67% by 2030. READ MORE

6. 5. THE PROSPECT OF LIVING FILTERS : Reducing building sector energy demands by improving indoor air quality

   University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Author : Joel Berglund; [2018]
   Keywords : Biological filters; air quality; ventilation engineering;

   Abstract : Today people spend all the more time indoors. Asthma, allergies and Sick Building Syndrome (SBS) are affecting an increasing number of people. READ MORE
