This study, a randomized controlled trial, evaluated the effectiveness of free-standing air filters and window conditioners (ACs) in 126 low-income households children with asthma. Households were into control group, group receiving HEPA filter placed child's sleeping area, window-mounted AC. Indoor quality (IAQ) was monitored for week-long periods over three to four seasons. High concentrations particulate matter (PM) carbon dioxide frequently seen. When IAQ monitored, reduced PM levels...
Air change rates (ACRs) and interzonal flows are key determinants of indoor air quality (IAQ) building energy use. This paper characterizes ACRs in 126 houses, evaluates effects these parameters on IAQ. measured using weeklong tracer measurements several seasons averaged 0.73 ± 0.76 h−1 (median = 0.57 h−1, n 263) the general living area, much higher, 1.66 1.50 1.23 253) bedrooms. Living area were highest winter lowest spring; bedroom summer spring. Bedrooms received an average 55 18% from...
Basements can influence indoor air quality by affecting exchange rates (AERs) and the presence of emission sources volatile organic compounds (VOCs) other pollutants. We characterized VOC levels, AERs, interzonal flows between basements occupied spaces in 74 residences Detroit, Michigan. Flows were measured using a steady-state multitracer system, 7-day measurements collected passive samplers both living areas basements. A walk-through survey/inspection was conducted each residence. AERs...
We assessed 45 multifamily buildings (240 apartments) from Finland and 20 (96 Lithuania, out of which 37 in 15 Lithuania underwent energy retrofits. Building characteristics, retrofit activities, consumption data were collected, Indoor Air Quality (IAQ) parameters, including carbon monoxide (CO), nitrogen dioxide (NO2), formaldehyde (CH2O), selected volatile organic compounds (benzene, toluene, ethylbenzene, xylenes (BTEX), radon, microbial content settled dust measured before after the...
Amid the backdrop of carbon neutrality, traditional energy production is transitioning towards integrated systems (IES), where model-based scheduling key in scenarios with multiple uncertainties on both supply and demand sides. The development artificial intelligence algorithms, has resolved issues related to model accuracy. However, under conditions high proportion renewable integration, component load adjustments require increased flexibility, so mathematical must adapt constantly changing...
INSULAtE-project assessed impacts of energy retrofits on indoor environmental quality and occupants' satisfaction. Most common retrofit actions included changing new windows installing heat recovery into exhaust ventilation system. This paper presents results related to in Finnish apartment buildings before after the retrofits. Average rates (from vents) with mechanical were 0.43 ACH 0.48 CO2 concentrations 750 ppm 715 retrofits, correspondingly. Percentage occupants satisfied IAQ was 22%...
We have conducted a project to develop common protocol for indoor environmental quality (IEQ) assessment and assess the effects of energy retrofits on IEQ. This paper focuses thermal comfort, which was first assessed based 2-month continuous monitoring in 16 multi-family buildings (94 apartments) Finland 20 (96 Lithuania during heating season before retrofits. In addition, corresponding data after were available from three (17 seven (30 Lithuania. Two loggers per apartment placed evaluate Tw...
A smart energy platform for the large-space stadium based on Internet of Things (IoT) is proposed. The could realize safe and stable operation system in various scenarios promote low-carbon, efficient sustainable development. In this paper, constructed IoT device data collection, time series storage, front-end platform, back-end optimization modules. architecture framework are explained details. This study takes a building Hangzhou as an example to explain how works real site. real-time...
For the building load prediction in district heating systems, traditional methods cover mechanism models and data-driven model. However, data of systems was often low quality or partly missing, thus cannot present high accuracy due to insufficient available for training. This paper proposed a model based on integration systems. The considered heat transfer process trained by historical data. As training results scenario data, presented remarkable improvement decreasing MAPE RMSE 7.34% 7.74%,...
