**Any home can be more energy-efficient**

Any home, no matter when it was built, can be energy-efficient. Modern construction
standards demand greater energy efficiency in new homes, but older homes can be 
upgraded to improve their energy performance. And the people living in these homes
can be energy-efficient in their habits, too.

**An energy-efficient home is…**

1024x738.jpg)

**Cost-effective**

It’s got a great EnerGuide rating. That means it’s well insulated and airtight, 
with high-efficiency heating and cooling equipment that helps keep utility bills
low. It’s outfitted with low-flow accessories to lower water consumption and water-
heating costs. The people living in this home keep inside temperatures reasonable,
use electricity wisely and buy ENERGY STAR^(®) certified products and appliances.

**Comfortable and healthy**

It’s warm in winter, cool in summer and free of drafts. The home has great ventilation
and excellent air quality; it’s never too humid or dry. The people living there 
use a programmable thermostat to manage heating and cooling at night and when they’re
away.

**Always adding value**

This home’s fixtures and upgrades show a commitment to energy efficiency that adds
resale value. Newer windows and doors, and high-efficiency lighting and appliances
not only save money and energy, they also look great to buyers. And investments 
in renewable energy like solar panels can pay off for years to come.

**Kind to the environment**

All the efficient features and elements work together to lower energy consumption,
reduce greenhouse gas emissions and shrink the home’s carbon footprint.

## Asbestos in drinking water, the norm in Quebec!

**On sait que l’eau est source de vie, mais peut-elle aussi être une source de fibre
d’amiante? L’amiante est un minéral fibreux qui a été largement utilisé par le passé
pour ses nombreuses utilisations, notamment dans le bâtiment. Le Québec occupait
d’ailleurs autrefois une place de choix dans l’extraction/exportation d’amiante 
chrysotile. Bien que l’encadrement de l’amiante fasse l’objet aujourd’hui d’un encadrement
relativement strict, il n’existe pas au Québec de norme sur la présence d’amiante
dans l’eau potable. Cette situation commence d’ailleurs à soulever l’intérêt dans
le public depuis le printemps.**

En effet, l’amiante peut se retrouver dans l’eau que l’on consomme. Il en existe
bien sûr de façon naturelle dans le sous-sol québécois, mais c’est surtout l’apport
des canalisations en fibrociment qui inquiète. La dégradation de ces canalisations
avec le temps peut relâcher des fibres dans le système de distribution d’eau potable
et être consommée par l’Homme.

**Risques pour la santé**

Les effets de l’exposition à l’amiante inhalée sont très bien connus. Cancer du 
poumon, mésothéliome, asbestose, l’amiante demeure la cause de décès professionnel
la plus fréquente chez nous. Toutefois, les effets de l’ingestion d’amiante, plutôt
que l’inhalation, restent mal connus. On sait que dans certains cas que l’on pourrait
qualifier d’extrêmes, l’amiante ingéré est lié à une incidence de cancers gastro-
intestinaux plus élevés. Le lien épidémiologique reste à confirmer, mais on se doute
donc qu’une ingestion continue de fibres pourrait causer une augmentation de ces
cancers (ex. : de l’estomac, rectal, de la rate, du colon, du pancréas, etc.).

L’agence américaine de protection de l’environnement possède, comme quelques autres
pays dans le monde, une norme sur la présence de fibres dans l’eau potable. C’est
de cette limite fixée à 7 millions de fibres par litre d’eau que le Québec pourrait
s’inspirer selon toute vraisemblance.

Cela peut sembler énorme, mais il faut se rappeler que ces fibres sont extrêmement
fines et que l’érosion des canalisations sépare les faisceaux de fibres d’amiantes
que l’on observe habituellement au microscope optique en fibrilles extrêmement fines
de l’ordre d’une vingtaine de nanomètres de côté (0.00002 mm). L’utilisation d’un
microscope à transmission d’électron est donc nécessaire pour cette analyse.

**Norme au Québec**

Pour se donner une échelle de comparaison avec la norme sur les fibres respirables(
1 fibre/ml pour le chrysotile), on doit d’abord se rapporter sur le même volume.

![](https://buildingexpert.ca/wp-content/uploads/2021/07/image-6.png)

| **Norme de l’eau **
 7 millions de fibres/litre = 7000 fibres/ml d’eau |

![](https://buildingexpert.ca/wp-content/uploads/2021/07/image-7.png)

| **Norme de l’air** 
1 fibre/ml d’air |

Ensuite, une « fibre respirable », ou plutôt « faisceau de fibres respirable », 
fait par définition jusqu’à 3 µm de largeur soit 0.003 mm. Si l’on considère, une
fibre unique d’amiante mesure 0.02 µm (0.00002mm), chaque faisceau de fibres respirable
contiendrait en réalité 60 000 fibres uniques parfaitement entassées les unes sur
les autres.

![L’attribut alt de cette image est vide, son nom de fichier est image-4.png.](https://
buildingexpert.ca/wp-content/uploads/2021/07/image-4.png)

| **Norme de l’eau**
 7 000 fibres /ml d’eau = Environ 0.00012 faisceau de fibres/ml |

![L’attribut alt de cette image est vide, son nom de fichier est image-5.png.](https://
buildingexpert.ca/wp-content/uploads/2021/07/image-5.png)

| **Norme de l’air** 
 1 fibre/ml d’air |

Cette comparaison est fortement biaisée par le fait que nous avons choisi les plus
gros faisceaux de fibres respirables permis par la définition et les plus petites
fibrilles décrites, mais ça démontre tout de même que la norme ne soit pas si permissive
qu’il n’y paraît et pourrait s’insérer logiquement dans une réglementation ayant
pour but de diminuer l’exposition de la population aux fibres d’amiante. Bref, vivement
un resserrement du contrôle sur l’eau que l’on consomme, pour la santé et la sécurité
des Québécois(es)!

## What you need to know about asbestos and its regulation.

**In recent years, Canada has finally followed the lead of most industrialized 
countries and banned the import and production of asbestos-containing materials,
decades after they were identified as the cause of many lung diseases. Although 
its use is now restricted or even banned, what about the remaining asbestos and 
its safety standards?**

First of all, asbestos refers to a group of commercially used minerals that have
the particularity of being highly fibrous. These minerals were mainly used for their
unique profile offering high malleability, strong resistance to heat, acids and 
moisture.

 **Where is asbestos found and why is it harmful?**

The different types of asbestos are likely to be found in just about any material
resulting from the mixing of several components. Insulation, flockings, cements 
and plasters as well as vinyl siding are some examples. It is also important to 
know that asbestos is sometimes found in certain products as a contaminant and not
because it has been added to benefit from its properties. Materials such as talc
or mica (vermiculite) may contain asbestos without being knowingly added.

The combination of properties that make asbestos a unique material is also the basis
of its harmfulness. Initially, asbestos can break down into fine fibrils that can
remain airborne for a long time and can easily travel far into the respiratory system.
Once in the alveoli, which are responsible for gas exchange (O2 and CO2), the fibers
persist despite the incessant attacks of the immune system thanks to their great
resistance. Physical damage, inflammation, and the accumulation of degradation enzymes
will, over time, cause significant damage that limits the efficiency of gas exchange
in the lungs and may encourage the development of certain cancers.

 **Stricter safety standards for asbestos removal workers**

Although Québec regulations are stricter than elsewhere in some respects, particularly
in the definition of what constitutes an asbestos-containing material, the exposure
limits to asbestos fibres are very high here.

Asbestos-producing countries, of which Canada was a member only a decade ago, are
generally more lax in their regulations and have historically defended the low toxicity
of asbestos at low doses. Now that Canada has aligned its position with that of 
the WHO and most of the European community, it goes without saying that we modify
the exposure thresholds accordingly. Des normes de sécurité plus strictes pour les
travailleurs chargés du désamiantage

Greater vigilance by authorities in enforcing existing rules should also be part
of a tightening plan. Examples of hazardous practices are legion, despite the presence
of a regulatory framework and the CNESST’s _Tolerance 0_ plan!

 **Does the presence of asbestos fibers automatically justify asbestos removal work
in a building?**

No, not necessarily. A building containing asbestos, but which is in good condition
and does not represent a high risk of degradation in the short or medium term, does
not require replacement work. Does the presence of asbestos fibers automatically
justify asbestos removal work in a building?

La présence de fibres d’amiante justifie-t-elle automatiquement des travaux de désamiantage
dans un bâtiment ?

Please note that when replacing insulation or sealing materials, owners can benefit
from grants for building improvements through energy efficiency programs such as
[Rénoclimat](https://buildingexpert.ca/en/energy/renoclimat/). However, there are
no specific programs for asbestos removal.

The presence of asbestos remains a major concern during renovation work and that
is why it is important to know its type and quantity. If you suspect the presence
of asbestos, you can call upon a competent laboratory in the identification of the
type of asbestos participating in an inter-laboratory testing program and being 
recognized by the Centre d’Expertise en Analyse Environnementale du Québec (CEAEQ),
as is the case for our laboratory, [LAB’EAU-AIR-SOL](https://labeauairsol.ca).
