Bulk airflow measurements in a large naturally ventilated atrium in a mild climate | 2017 | English | 9 pp
In recent years, concerns about global warming and greenhouse gas emissions have motivated designers to reduce building energy consumption through the implementation of passive solutions without compromising users’ thermal comfort.
Design and performance of ventilative cooling: a review of principals, strategies and components from International case studies | 2017 | English | 11 pp
Overheating is an unwanted consequence of modern building designs and internal gains that will be aggravated by the effects of climate change on local climates within urban and suburban areas.
A comparison study of the blower door and novel pulse technique on measuring enclosure airtightness in a controlled environment | 2017 | English | 10 pp
This paper introduces a comparison study of measuring the airtightness of a house sized test chamber using the novel pulse technique and the standard blower door method in a controlled environment.
Recirculation hoods equipped with carbon and plasma filters are becoming more and more popular.
A novel algorithm for demand-control of a single-room ventilation unit with a rotary heat exchanger | 2017 | English | 10 pp
Energy renovations seek to improve the airtightness of dwellings and thus require ventilation and heat recovery to maintain or improve energy-efficiency, indoor climate, and durability.
Experimental evidence of effective single sided natural ventilation beyond 20ft or 2.5 floor to ceiling heights in open plan office spaces | 2017 | English | 2 pp
Most natural ventilation (NV) systems used in non-residential buildings are single sided (SS).
A longitudinal field study of thermal comfort and air quality in naturally ventilated office buildings in UK | 2017 | English | 9 pp
Natural ventilation has the potential to provide cooling and fresh air and cut 40% of the total energy consumption of European office buildings.
The effect of refurbishment and trickle vents on airtightness: the case of a 1930s semi-detached house | 2017 | English
As UK homes are insulated and draught proofed in an attempt to reduce wintertime heating demand they become more airtight. Any reduction in infiltration could have a detrimental effect on indoor air quality.
The lack of indicators assessing ventilative cooling effectiveness in a way to compare it with active cooling technics, makes its acceptance more difficult.
Method development for measuring volatile organic compound (VOC) emission rates from spray foam insulation (SPF) and their interrelationship with indoor air quality (IAQ), human health and ventilation strategies | 2017 | English | 12 pp
The polyurethane foam industry is projected to reach a worldwide value of up to $74bn by 2022 and with airtightness of new and retrofitted properties continually increasing, an important question arises: what is the impact of these materials on th
Ventilative cooling potential based on climatic condition and building thermal characteristics | 2017 | English | 9 pp
We introduce a new method for defining ventilative cooling potential (VCP) for office buildings that depends not only on the climatic conditions but also on building thermal characteristics.
Towards Real-Time Model-Based Monitoring and Adoptive Controlling of Indoor Thermal Comfort | 2017 | English | 7 pp
Thermal comfort is an important aspect of the building design and indoor climate control as modern man spends most of the day indoors.
The flow interaction of air distribution with thermal plumes and the effect on the air velocity fluctuation under increased heat load conditions | 2017 | English | 10 pp
Flow interaction between thermal plumes and vertical air distribution and the resulting airflow structures were investigated under increasing heat load conditions.
Inter-model comparison of indoor overheating risk prediction for English dwellings | 2017 | English | 10 pp
According to the 2016 Household Projections report, England’s housing stock could reach 28 million households by 2039 with approximately one fifth being new constructions.
An interface of night ventilation and mass structure for passive cooling design strategy in Ghadames traditional dwellings | 2017 | English | 7 pp
The effectiveness of night ventilation strategy for residential buildings in the old town of Ghadames has been investigated in this study.
Field measurement of carbonyl compound and particles in South Korea residential spaces | 2017 | English | 8 pp
In Korea, a large amount of fine dust and carbonyl compounds is generated during cooking in the kitchen.

The Royal Wanganui Opera House (RWOH), in Whanganui, New Zealand, was constructed in 1899, and now seats 830 people.
Indoor air quality in mechanically ventilated residential dwellings/low-rise buildings: A review of existing information | 2017 | English | 10 pp
Mechanical ventilation has become a mandatory requirement in multiple European standards addressing indoor air quality (IAQ) and ventilation in residential dwellings (single family houses and low-rise apartment buildings).
Pollutant exposure of the occupants of dwellings that complies with the Spanish indoor air quality regulations | 2017 | English | 6 pp
The Spanish Technical Building Code establishes the criteria for indoor air quality fixing minimum and constant ventilation rates per local.
