Energie• Energie :
• En joule : 1 Watt pendant 1 seconde = 1 joule
• En kWh : 1 kWh = 3,6 Mégajoule (3,6 x 106 J)
• …mais aussi en calorie (1 kcal = 4180 J) ou en thermie (1 th = 1000 kcal)
• Permet selon le cas de produire un mouvement, de la lumière ou de lachaleur…

PuissancePuissance: En Watt
L’énergie est une puissance développée pendant uncertain temps : E = P x t
• Une lampe de 100 W fonctionnant pendant 1h nécessitera 100 Wh
• Une lampe de 100 W fonctionnant pendant 10h nécessitera 1000 Wh soit 1 kWh.

Température• Température : En degré Celsius (°C) ou en Kelvin (K)
• 0 K = -273°C : Zéro absolu
• Une hausse de température d’un corps correspond à un apport d’énergie.

Transfert thermique
• Définition simplifiée :• Un transfert thermique est un transfert d’énergie entre deux corps à
températures différentes.
• Le corps le plus chaud cède de la chaleur (de l’énergie) au corps leplus froid.
• Cela crée un flux de chaleur ou flux thermique.

Flux thermique
• Energie échangée entre deux milieux de températures différentes par unité de temps
• Le flux thermique H s’exprime en Watt (Puissance)
• On parle plus généralement de densité de flux h (en W/m²) : fluxthermique à travers une surface

2. Building Physics - Thermal Principles
![Page 12: CO - Wall Ace](https://reader036.vdocuments.us/reader036/viewer/2022062416/62ad665bfab2f212b627f620/html5/thumbnails/12.jpg)
3 types de transferts
• Conduction
• Convection
• Rayonnement
12
Les principes généraux de la transmission de la chaleur sont universels et les mêmes mécanismes se retrouvent, à différents niveaux d’importance, dans tous les échangesthermiques de l’enveloppe d’un bâtiment.
![Page 13: CO - Wall Ace](https://reader036.vdocuments.us/reader036/viewer/2022062416/62ad665bfab2f212b627f620/html5/thumbnails/13.jpg)
La conduction
La Transmission de la chaleur par conduction (concerneprincipalement les corps solides) et les fluides.
• La propagation de la chaleur dépend d’une propriété intrinsèque à chaque matériau – La conductivité thermique
13
• Conductivité thermique – (En W/m.K)
• Plus est élevé, plus le matériau conduit lachaleur.
![Page 14: CO - Wall Ace](https://reader036.vdocuments.us/reader036/viewer/2022062416/62ad665bfab2f212b627f620/html5/thumbnails/14.jpg)
La convection
Transmission de la chaleur par convection (concerneprincipalement les gaz et les fluides). L’air circule par différencede température entre deux points en raison de la variation demasse volumique. Par exemple, l’air chaud monte et la chaleurse dissipe en « frottant sur les parois »
14
![Page 15: CO - Wall Ace](https://reader036.vdocuments.us/reader036/viewer/2022062416/62ad665bfab2f212b627f620/html5/thumbnails/15.jpg)
Le rayonnement
Transmission de la chaleur par rayonnement (infrarouge).Toute matière absorbe et émet un rayonnement en fonction desa température et de son émissivité, l’échange de chaleur sefaisant en fonction du vecteur de propagation (air ou vide). Letransfert de chaleur par rayonnement ne nécessite pas devecteur de propagation.
• Tout corps chauffé émet un rayonnement infrarouge dont la
longueur d’onde dépend de la température.
• Un corps est chaud si sa température est supérieure à
273°C (0° K)

Le bâtiment: La qualité de l’enveloppe
• Une enveloppe de qualité pour une efficacité énergétique des bâtiments s’obtient par une stratégie de moyens économiques, accessibles, faciles à mettre en oeuvre et apportant des bénéfices conjugués autant pour le confort individuel que pour la préservation de la planète.
• Le bâtiment a tout à gagner.

• Les ponts thermiques entre parois verticales et horizontales
Plancher bas / mur Plancher intermédiaire / mur Plancher haut / mur
Les déperditions dues aux liaisons structurelles contribuent au
calcul des déperditions surfaciques au stade de la définition du
calcul du total des déperditions du bâtiment : Ubât projet.C’est aussi un coefficient linéique . Les ponts thermiques
correspondent aux liaisons, le plus souvent structurelles,
planchers refends, angles, fenêtres-parois, etc. Leurs valeurs
sont données dans les règles ThU ou par calcul.
L’intégration des ponts thermiques de liaison dans le calcul du
Ubât correspond à la moyenne pondérée des déperditions
thermiques de l’ensemble des parois d’un bâtiment. Le Ubât
permet d’exprimer de façon synthétique la performance globale
d’un bâtiment pour 1m² de paroi
Le pont thermique de liaison est calculé en fonction desa longueur et est ramené à une surface de paroi.

Notion of Thermal Confort

A subjective feeling…
28
• Confort thermique = Environnement thermique nous procurant une sensation de bien-être.
• Dépend de paramètres qui varient d’un individu à l’autre:
• Physiques• Physiologiques• Psychologiques
• Difficile de définir des conditions « optimales » dans un cas général.
![Page 29: CO - Wall Ace](https://reader036.vdocuments.us/reader036/viewer/2022062416/62ad665bfab2f212b627f620/html5/thumbnails/29.jpg)
Les échanges thermiques
• Notre corps échange avec son environnement selon les 3 principesde base :
• Convection : l’air qui nous entoure nous réchauffe ou nousrefroidit.
• Rayonnement : les objets, les murs qui nous entourentéchangent de la chaleur avec nous.
• Conduction (Négligeable) : on échange de l’énergie avec lesobjets que l’on touche (carrelage).

Internal high performance insulating plaster (VIMARK)
• SUBSTRATE PREPARATION / PRE-TREATMENTTHERMAL PLASTER can be used on any kind of masonry: brick, blockwork, expanded or lightweight
concrete, brick-cement, mineralized wooden boards, scrim or metal lath, old plaster, etc.
The surfaces must be resistant, clean, fixed, free from brittle parts, dust, bacterial proliferation, saline
efflorescence, oils, grease, wax, residues of previous work, etc. If necessary, clean the surface by
sandblasting or pressure washing.
Smooth concrete or non-absorbent and compact surfaces need to be treated first by applying a layer of
MICROGIRP to improve plaster mortar adhesion to supports. Plaster has to be applied after 2 hours from
the application of the primer coat.
Use THERMAL PLASTER for the preparation and application of intermediate layers. If wooden or metal
battens are used, remove them immediately after applying the thermal insulation render mortar, filling the
gaps with THERMAL PLASTER.
Prepare corner beads, level guides, etc. before applying the plaster layer on the wall. The edges and openings for doors and windows can be previously prepared with the installation of steel corner beads fastened by screw or plastered in. You can also use wooden battens for edges but with less effective results. In case you need to reinforce the edges obtained, apply on coating layer the PARASPIGOLO CAPPOTTO PVC.

Internal high performance insulating plaster (VIMARK)
• MIXING AND APPLICATION: THERMAL PLASTER can be applied by mechanical spraying, using a plastering machine for pre-mixed products, or by hand.
• For manual application, mix the product by adding approx. 30 litres of clean water per bag. Pour water into the cement mixer then add thepowder. Mix the product for about 5 minutes until the mixture is smooth and free of lumps. The mixed product is usable within 60minutes after mixing with water. Use a large trowel to install the product in several layers, until the desired thickness is obtained.
• For application by mechanical spray, set up the plastering machine with a large blade helical mixer of a rotor/stator group specific forlightweight products. Apply an initial layer of about 10 mm of product to the whole surface. Wait for it to set before proceeding with thenext layer of thickness (from 4 to 24 hours depending on the conditions of application). To achieving the desired thickness, proceed withthe application of successive layers between 20 and 30 mm thickness. Level out and finish the plaster layer with an aluminium screed bar.Any smudges or excess product is to be eliminated by scraping and sanding the supports. The prepared surfaces are then suitable fortreating with finishing products.
• Some undesired effect may also occur, such as the cracking of the first coat or of the intermediate layers but, note that they will not affectthermal and mechanical performances of the product. Cracking may be due to the water absorption by the substrate, that was notproperly treated before installation, or to the warm and dry air of the indoor room that speeds up evaporation and induces shrinkage ofthe product.
• Wait at least 10 days before proceeding with final coating. In order to guarantee a proper adhesion of the coats, a period of curing isnecessary to allow the evaporation of 90% of excess water, present in the plaster mortar.
• When the coating is applied to early, a web shape cracking may happen as well as the detachment of the coating from the plaster, due tothe release of the moisture content of THERMAL PLASTER, and the stress caused by the handmade levelling.
• The coating shall be applied to the whole area with a metal trowel in a even thickness of 3 mm minimum. Primed and certified fibreglassARMANET 4x4 mesh with alkali treatment shall be needed to reinforce the surface. Apply the mesh from top to bottom of the wall, takingcare of overlapping strips by at least 10 mm. Once the layer has set, apply a second coat to make the entire surface uniform.
• For the interiors, gypsum-based coating can be used. Products having a low breathability are not recommended. The indicated maximumthickness respects the maximum bearing capacity of the THERMAL PLASTER layer, and avoids risks of detachment from the support.
• The application of a coating finish is also recommended as mechanical protection in case of collisions or as base for the aesthetics finishinglayer, chosen by the customer.

Insulating thermal coating finishing (VIMARK)
• SUBSTRATE PREPARATION / PRE-TREATMENT
THERMAL COATING can be applied to any traditional mineral surface: traditional lime plaster, pre-mixed
plaster, lime-cement mortar, plasterboard, painted surfaces, or traditional supports.
The surfaces to be treated must be smooth, stable, clean, consistent, free of dust, bacteria proliferation,
efflorescence, salt, oil, grease, wax, residue of previous work etc. Before applying THERMAL COATING
make sure that the surface is solid, sufficiently resistant and seasoned and it is not subject to movement or
shrinking. Smooth and humid surfaces must be cleaned with specific products according to the type of
material on the substrate or properly sanded.
A layer of MONOGRIP is recommended to prepare the surface. The primer must be applied to the whole surface at least 12 hours before the installation of THERMAL COATING.

• MIXING AND APPLICATION:
Insulating thermal coating finishing (VIMARK)
• Mix a 30 litres bag of THERMAL COATING with approx. 30-31 litres of clean water using an electric mixer
until the blend is smooth and free of lumps. Let set for 3 minutes and mix again before applying.
• The product can be used within the next 60 minutes.
• Do not add water or mix to use the product after this period.
It is advisable to apply the first coat of THERMAL COATING using an 8x8 mm or a 10x10 mm trowel with rivets. Apply a thin layer first using the flat side of the trowel to the surface, then proceed to apply the successive coating with the riveted side of trowel. Setting phase completed, apply a second hand of coating to unify the whole surface. For the final layer, an even thickness and smoothness is reached by using a stainless steel trowel. Suggested coating thicknesses are between 5 and 10 mm. After 72 hours the surface will be ready for one of the Vimark’s finishes.
