LoginComfort modelling is a critical scientific barrier to reaching better thermal satisfaction in buildings. It allows designers to combine different cooling systems better to target comfortable low-energy buildings in hot and tropical climates.
Bibliographic database Airbase
AIRBASE is the Bibliographic Database of the AIVC. It contains publications and abstracts of articles related to energy efficient ventilation. Where possible, sufficient detail is supplied in the bibliographic details for users to trace and order the material via their own libraries. Topics include: ventilation strategies, design and retrofit methods, calculation techniques, standards and regulations, measurement methods, indoor air quality and energy implications etc. Entries are based on articles and reports published in journals, internal publications and research reports, produced both by university departments and by building research institutions throughout the world. AIRBASE has grown and evolved over many years (1979 to present day, over 22000 references and 16000 documents available online). For most of the references, the full document is also available online.
Access to the publications is free of charge.
Airtightness is presented through various expression according to the standards and measurement methods of each country.
At hospitals and healthcare buildings, the ultimate objective is to save lives.
We need to improve the indoor air quality for the health of the building users, and we need to optimize and reduce energy consumption for heating, cooling, and ventilation for the sake of the global climate.
(numbered VIP 45.XX), detailing for both building and ductwork airtightness:
The ASHRAE Standard Project Committee on Ventilation and Acceptable Indoor Air Quality in Residential Buildings (62.2) has proposed an addendum to the standard that adds a harm-based Indoor Air Quality procedure as an alternative compliance method
Due to its high demands regarding indoor environmental conditions, healthcare facilities are associated with high energy consumption.
Airtight, highly insulated, and passively cooled buildings in the EU are designed under typical outdoor and indoor thermal conditions.
The AIVC is preparing a series of VIP on national regulations and trends in airtightness for various countries (numbered VIP 45.XX), detailing for both building and ductwork airtightness:
The importance of ventilation of spaces for occupants’ health has been known for many years. Ancient Egyptians used natural ventilation to remove dust and thus to reduce respiratory diseases of stone carvers working indoors (Janssen 1999).
The need for airtightness control is a reality given its impact on buildings’ energy use and IAQ. For the past few years, this fact has resulted in energy performance regulations being established in many countries in Europe and North America.
Airborne exposure has been highlighted during the COVID-19 pandemic as a probable infection route.
Due to the minimal energy requirement, the Passivhaus standard has been widely recognised and adopted to deliver low carbon buildings.
The Performance 2 project (2020-2024) is a French national research project that aims to evaluate the durability of Humidity-based Demand Controlled Ventilation (DCV) systems installed in two multi-family social housing buildings (Paris and Villeu
The installation of central mechanical ventilation with heat recovery (MVHR) in renovated apartment buildings presents considerable challenges, primarily due to insufficient space for ductwork.
In the United States, the realm of building enclosure design and commissioning is separate and distinct from the realm of mechanical design and commissioning.
We performed residential indoor fine particle (PM2.5) measurement from 26 homes and three outdoor monitoring locations.
Due to global warming, severe problems of buildings overheating during summer in temperate and hot climates arise. Thus, there is an increasing use of air conditioning.
Since 2018, Renson has introduced a range of cloud-connected residential ventilation systems, including central and decentral mechanical extract ventilation (MEV), as well as fully mechanical systems with heat recovery (MVHR) (see Fig. 1).
This manuscript discusses the energy-saving benefits of gas-phase air cleaning in Nordic buildings. Ventilation systems are crucial in creating a healthy and comfortable indoor environment.
