Regional climate change in cities is the most documented phenomenon of climate change . Higher urban temperatures are  documented experimentally for more than 450 major cities in the world.

Traffic sources contribute a large portion of the ambient nitrogen dioxide, particulate matter and ozone concentrations, the three ambient air pollutants with the largest impact on human health in Europe (EEA, 2018).

Smartness is all around us. The HVAC industry is developing more and more products that have sensors, are intelligent, are connected to the Internet and are being controlled via apps.

In future building regulations 2020, building performance is going to be extended to global performance, including indoor air quality (IAQ).
Gaëlle Guyot
In the field of energy performance, successive regulations pushed a "performance-based" approach, based at least on an energy consumption requirement at the design stage for heating and/or cooling systems (Spekkink 2005).
François Parsy, Gaëlle Guyot
As a consequence of the sustainable politics demanding regulations that allow the use of more efficient ventilation systems, the IAQ Spanish regulations were modified and enforced in 2017.
Pilar Linares, Sonia García
Performance based approached for ventilation started to be used in Belgium in 2008 in the context of EP regulation.
Samuel Caillou, Sébastien Pecceu
Demand controlled ventilation (DCV) seems to be the main way to comply with both energy and internal air quality (IAQ) concerns.

The building airtightness is essential to achieve a high energy performance. In most countries however, it is not mandatory to measure the airtightness. In the Netherlands it is common practice to just take a couple samples in a housing project.
Timothy Lanooy, Niek-Jan Bink, Wim Kornaat, Wouter Borsboom
Previous studies have compared the airtightness measurement of test enclosures utilising both the novel Pulse technique and the conventional blower door method.
Xiaofeng Zheng, Luke Smith, Adam Moring, Christopher J Wood
Building airtightness is a critical aspect for energy-efficient buildings as energy performance of a building can be reduced significantly by poor airtightness.
Yun-Sheng Hsu, Xiaofeng Zheng, Edward Cooper, Mark Gillott, Shin-Ku Lee, Christopher J Wood
Requirements for measuring the building airtightness have been proposed and included by many countries for national regulations or energy-efficient programs to address the negative effect of poor airtightness on building energy performance, durabi

Heating energy in buildings represents a significant proportion of the total global energy consumption. Uncontrolled airflow through the building envelope contributes significantly to its energy losses.  
Benedikt Kölsch, Björn Schiricke, Jacob Estevam Schmiedt, Bernhard Hoffschmidt
Mandatory building airtightness testing has come gradually into force in European countries, mostly because of the increasing impact of building leakage on the overall energy performance of low-energy buildings.
Valérie Leprince, Christophe Delmotte, Isabelle Caré
HVAC systems in newly built or extensively renovated dwellings were all developed with the aim for energy saving with equal or better comfort.
Klaas De Jonge, Jelle Laverge
Duct routing often poses a great challenge when planning the installation of a mechanical ventilation system with heat recovery.
Gabriel Rojas, Rainer Pfluger
Humidity-based DCV systems have been widely used in France for 35 years and are considered as a reference system, including for low-energy residential buildings.
Gaëlle Guyot
The present paper aims at illustrating the practical use of the Annex68 IAQ Dashboard. To this end, numerical simulations have been performed to provide useable data about the Indoor Air Quality (IAQ) of a low-energy detached house.
