Industry Views with Respect to Smart Ventilation as an Enabler of Indoor Air Quality

What if all the devices in your life could connect to the internet? Not just computers and smartphones, but everything: clocks, speakers, lights, door bells, cameras, windows, window blinds, hot water heaters, appliances, cooking utensils, you name it. And what if those devices could all communicate, send you information, and take your commands. 

Energy labeling system for residential building in China

Residential Building Energy Efficiency (RBEE) becomes more important in recent years in China. From 1986, Chinese government has carried out a series of codes of RBEE, but for kinds of reasons, the effect is not perfect enough. One important reason is In order to promote the development of RBEE, an energy labeling system was presented in this paper. In this labeling system, the real estate company was requested to label the energy consumption data of the houses to be sold on the sales documents, and show this data to the consumers.

Control of airtightness quality management scheme in France: Results, lessons and future developments

Since January 1st 2013, the French energy performance (EP) regulation requires building airtightness level to be justified to a lower-than-required value. These requirements represent an important change in the airtightness market. As a consequence, it is the State’s responsibility to accompany this market evolution and to supervise the implementation of the quality in building airtightness. French regulation allows two ways to justify the airtightness value for the building envelope.

Airtightness Quality Management scheme in France: Assessment after 5 years operation

From 2006 till 2012, the 2005 energy performance (EP) regulation (RT 2005) did not entail any obligation to justify the envelope airtightness level. As a consequence, asking for the certification of airtightness quality management approaches was a voluntary request from constructors. Thus, they might be allowed to take into account a better-than-default value into the thermal calculation. Since 2012, French 2012 EP regulation (RT 2012) requires building airtightness level to be justified, with two ways of justification.
