Robust and reliable deep renovation by advanced prefabricated façade elements. Air-tightness performance and assessment of a demo case
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)Deep renovation of the existing building mass is an important task to reach the target of energy efficient buildings and neighbourhood. However, the current renovation rate is only 1% of the European building stock each ... -
Demand-controlled ventilation in schools: Influence of base ventilation rates on subjective symptoms, perceived indoor environment and young adults' learning performance
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)The ventilation airflow rates in a demand-controlled ventilation strategy typically vary between a base (Vmin) and a maximum ventilation rate (Vmax). Classrooms have relatively short but intense hours of occupancy and a ... -
Development and Application of a Ventilation System Based on Vertical Descendent Confluent Jets
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)This paper presents the development and application of a ventilation system based on vertical confluent jets. The thermal comfort and indoor air quality levels, Air Distribution Index and energy consumption are evaluated ... -
Investigation of work-practices, skills and everyday challenges of building operators with respect to indoor climate and energy
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)Focus on sustainable construction brings many requirements and standards to ensure energy efficiency and high indoor environmental quality (IEQ). However, these are mainly used in design phase. Commissioning becomes ... -
Measurements of indoor air quality in four Norwegian schools
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)Children spend a minimum of six hours per day in Norwegian schools. Their exposure to different indoor air quality it is known to affect their performance. It is very common to use demand-controlled ventilation ... -
Prediction of Electricity Consumption of a HVAC System in a Multi-Complex Building Using Back Propagation and Radial Basis Function Neural Networks
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)This study examined approaches to predict electricity consumption of a Heating, Ventilation and Air- Conditioning (HVAC) system in a multi-complex building using two neural network models: Back Propagation (BP) and Radial ... -
Thermal Comfort Level of Patients and Surgical Staff in Operating Rooms at Nordic Hospital
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)In healthcare facilities and hospital environment, it is essential to enable thermal comfort for occupants. Unstable thermal conditions in the operating room (OR) will influence the performance of surgical staff and ... -
The influence of indoor air quality in classrooms on the short-term academic performance of students in higher education; a field study during a regular academic course
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)The indoor air quality (IAQ) in classrooms in higher education can influence in-class activities positively. In this context, the actual IAQ and students’ perceived IAQ (PIAQ), perceived cognitive performance (PCP), and ... -
Operation status and improvement of the integrated hybrid VRF system
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)In recent years, the demand for energy conservation, the best energy mix, and thus air conditioning with energy options has increased. For this purpose, an integrated hybrid Variable refrigerant flow system (called hybrid ... -
Better building operation, maintenance and well-being in apartments with smart indoor climate meters
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)The justification of energy consumption in dwellings is to maintain comfortable and healthy indoor climate. Sufficient air exchange and comfortable temperatures protect building structures against mould growth caused by ... -
Can we trust what humans report? – myths and realities
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)Human information is crucial for efforts in the field of buildings, health and experiences. Despite this, there is strikingly little focus on how it is created and may be understood. Division between e.g. “subjective”/ ... -
Experimental study on the thermal plume from a surgeon in an operating room with mixing ventilation during COVID-19 pandemic
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)Following the outbreak of COVID-19 (SARS-CoV-2) in 2019, studies show positive results in protecting the surgical staff from patients infected by COVID-19 in operating rooms (ORs) with negative pressure. A negative pressure ... -
Schools on hold – how simple measures can help improving the indoor environment in schools
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)This work presents the lessons-learned from a Norwegian project called "Skoler på vent" – "Schools on hold" – which is aiming at finding simple and effective measures for improving the indoor climate in schools that have ... -
Indoor Environment and Energy Consumption of an Elementary School in a Subtropical Region
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)Indoor thermal environment and air quality in an elementary school were measured and examined for the basic data of net Zero Energy Buildings (ZEBs) and the adaptation to the impacts of climate change. The target school ... -
Assessing the indoor air quality of natural-ventilated bedrooms in renovated Norwegian houses using detailed field measurements
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)The objective of this work is to investigate the indoor environment in bedrooms ventilated by window opening during night-time.
