Animation - Wind Effect on Energy Efficiency
(24 Seconds  )

When the wind blows, it increases the pressure on the upwind side of the home and decreases the pressure on the downwind side.

 
Item LockedAnimation - Wind Effect on Energy Efficiency (Commerical)
(32 Seconds  )

When the wind blows, it increases the pressure on the upwind side of the building and decreases the pressure on the downwind side.

 
Animation - Stack Effect on Energy Efficiency
(1 Minute  28 Seconds  )

The stack effect occurs because air that is heated is lighter than cold air.

 
Item LockedAnimation - Stack Effect on Energy Efficiency (Commerical)
(53 Seconds  )

The stack effect occurs because air that is heated is lighter than cold air.

 
Animation - First Heat Flow : Conduction
(1 Minute  25 Seconds  )

Conduction occurs when a material separates an area of high temperature from an area of low temperature, such as a wall.

 
Item LockedAnimation - First Heat Flow : Conduction (Commercial)
(1 Minute  18 Seconds  )

Conduction occurs when a material separates an area of high temperature from an area of low temperature, such as a wall.

 
Animation - Second Heat Flow : Convection
(2 Minutes  48 Seconds  )

Heat transfer by convection occurs as a result of movement of liquid or gas over a surface. There are two types of convection, forced and natural.

 
Item LockedAnimation - Second Heat Flow : Convection (Commercial)
(2 Minutes  31 Seconds  )

Convection occurs as a result of movement of liquid or gas over a surface. There are two types of convection, forced and natural.

 
Animation - Third Heat Flow : Radiation
(1 Minute  32 Seconds  )

Radiation heat transfer is by invisible electromagnetic waves from one object to another.

 
Item LockedAnimation - Third Heat Flow : Radiation (Commerical)
(1 Minute  24 Seconds  )

Radiation heat transfer is by invisible electromagnetic waves from one object to another. Heat transfers from areas of higher temperature to areas of lower temperature.

 
Item LockedAnimation - Mechanical Effect on Energy Efficiency
(1 Minute  7 Seconds  )

The mechanical effect includes exhaust ventilation and room pressurization as a result of air movement caused by the HVAC system.

 
Animation - Flue & Ventilation Effects on Energy Efficiency
(1 Minute  13 Seconds  )

The flue effect occurs in all houses that have an open chimney serving some kind of combustion appliance. / The ventilation effect: Many homes are equipped with mechanical ventilation devices that exhaust air from the home, including bathroom and kitchen fans, clothes dryers and central vacuum systems.

 
Animation - System Effect on Energy Efficiency
(2 Minutes  23 Seconds  )

A forced air heating system uses a powerful fan to distribute heated and cooled air throughout the home.

 
Presentation - System Performance Testing
(1 Minute  52 Seconds  )

How to evaluate HVAC and building envelope systems to make sure they are performing properly.

 
Item LockedPresentation - Air Barriers Systems
(3 Minutes  0 Seconds  )

Item LockedPresentation - Air Flow Paths
(1 Minute  9 Seconds  )

Direct flow/ Diffuse flow/ Channel flow.

 
Item LockedPresentation - Minimize the Impact of Stack Effect
(5 Minutes  11 Seconds  )

The purpose of compartmentalization is to isolate connecting spaces to minimize the impact of stack effect.
