A review of performance-based approaches to residential smart ventilation

In order to better address energy and indoor air quality issues, ventilation needs to become smarter. A key smart ventilation concept is to use controls to ventilate more at times it provides either an energy or IAQ advantage (or both) and less when it provides a disadvantage. This would be done in a manner that provides improved home energy and IAQ performance, relative to a “dumb” base case. This paper highlights that a favourable context exists in many countries, with regulations and standards proposing “performance-based approaches”.

Accuracy Improvement for Estimating Indoor Carbon Dioxide Concentration Produced by Occupants

Carbon dioxide included in exhaled breath is often used as a tracer gas when estimation of ventilation aspect in buildings with occupants is performed. Indoor carbon dioxide concentration is also adopted evaluation of ventilation commonly. It is needed for these investigations to grasp occupants’ carbon dioxide production rate accurately. 

Thamesmead Condensation, Damp and Mould Strategy. The use of smart thermostats to assess ventilation interventions with demand controlled ventilation

An implementation of a Condensation, Damp and Mould (CD&M) Strategy for the Thamesmead estate in south-east London Targeting 2000 homes. The evidence-based strategy is designed to manage CD&M systematically and focus on homes that will not be refurbished or replaced for some time. CD&M risk assessments and surveys are used to identify homes for a range of interventions, including energy advice, smart heating controllers and demand-controlled mechanical extract ventilation, in various combinations.

The assessment of surface condensation risk in dwellings. The influence of climate in Spain

Surface condensation risk is a fact that has to be dealt with when buildings are airtight. Airtight buildings with lower ventilation rates are the result of applying energy saving policies and criteria. Surface condensation risk depends greatly on the ventilation rates, as well as on another factors such as generation of water vapour, climate, envelope components and U value, etc.

Performance of a dual core energy recovery ventilation system for use in Arctic housing

The extremes of arctic climate pose severe challenges on housing ventilation systems, energy consumption and demand for space heating for northern remote community residential buildings. As a part of the overall effort to reduce space heating requirements, dwellings are built air tight to reduce heat losses. However, airtight homes require energy efficient and effective ventilation systems to maintain acceptable indoor air quality and comfort, and to protect the building envelope from moisture damage.

27-28 March, 2019 | Quality ventilation is the key to achieving low energy healthy buildings

Sustainable Energy Authority of Ireland (SEAI) together with the Air Infiltration and Ventilation Centre (AIVC) organised a symposium entitled “ Quality ventilation is the key to achieving low energy healthy buildings ” held on 27-28 March 2019 in Dublin, Ireland. 

The 2 day workshop provided a wealth of insights from experiences both nationally and internationally. It informed approach on ventilation as a key component of delivering both new buildings and deep retrofit low energy buildings.
