What Are The Key Features Of A Passive House?

• No thermal bridging.
• Superior windows.
• Mechanical ventilation with heat recovery.
• Quality insulation.
• Airtight construction.

What are the 3 main things to consider when designing for passive solar?

The key to designing a passive solar building is to best take advantage of the local climate performing an accurate site analysis. Elements to be considered include

window placement and size, and glazing type, thermal insulation, thermal mass, and shading

.

What are the properties of a passive solar house?

• Insulation and air sealing.
• Window location, glazing type, and window shading.
• Thermal mass location and type.
• Auxiliary heating and cooling systems.

What are the basic elements of passive solar design?

The key aspects of passive solar design are:

thermal mass, insulation, angle and direction of the sun (orientation), windows (placement and operable), overhangs and shading, ventilation and circulation, surface colors, and geographical location

(see Figure 1).

What is the passive function of a house?

The Passive House is the world leading standard

in energy-efficient construction

: A Passive House requires as little as 10 percent of the energy used by typical Central European buildings – meaning an energy savings of up to 90 percent. Owners of Passive Houses are barely concerned with increasing energy prices.

What are the 5 Passive House principles?

• Airtightness.
• Thermal insulation.
• Mechanical ventilation heat recovery.
• High performance windows.
• Thermal bridge free construction.

Why is passive house important?

One of the main benefits of Passive Housing is

the energy cost savings

. These homes must adhere to strict building criteria, consuming up to 90% less heating and cooling energy when compared to conventional buildings. This results in energy cost savings of approximately 60 to 80% overall.

What are some examples of passive solar design?

Passive Solar Energy

Greenhouses and sunrooms

are examples of passive designs. The sun’s rays pass through the windows, and the structure’s interior absorbs and retains the heat. Homes, offices and industrial buildings can be designed with passive solar systems in mind, in order to gain the most benefit.

What is a passive solar technique?

Passive solar technologies

convert sunlight into usable heat and cause air movement for ventilating to heat and cool living spaces

without active mechanical or electrical devices.

What is the difference between active and passive solar?

Solar energy systems use the sun’s rays for electricity or thermal energy. … Passive systems are structures whose design, placement, or materials optimize the use of heat or light directly from the sun.

Active systems have devices to convert the sun’s energy into

a more usable form, such as hot water or electricity.

What are passive techniques?

Passive techniques employ

special surface geometries

(e.g., surface coatings, fins, inserts, curved tubing, surface tension devices) or additives (e.g., microparticles, nanoparticles, phase change materials, surfactants) for heat transfer enhancement.

What is passive solar home design?

In simple terms, a passive solar home

collects heat as the sun shines through south-facing windows and retains it in materials that store heat

, known as thermal mass. … Well-designed passive solar homes also provide daylight all year and comfort during the cooling season through the use of nighttime ventilation.

What are the passive design strategies?

• Emphasize Cross Ventilation. …
• Keep Spaces Open. …
• Rethink Mechanical Design. …
• Control Heat. …
• Have Optimal Insulation. …
• Use High-Performance Windows and Doors. …
• Have Proper Solar Orientation. …
• Design an Airtight Envelope.

How do you get a Passive House?

1. 1 – High quality insulation. Rule number one when it comes to Passive House is to get your building envelope in check. …
2. 2 – Heat control and robust windows. …
3. 3 – Airtight construction. …
4. 4 – Heat recovery ventilation. …
5. 5 – Thermal bridge free design.

Are passive houses expensive?

Currently, a

passive house typically costs about 5-10% more than a conventional home

. Larger projects benefit from the economy of scale: a multifamily passive building typically only costs 0-3% more than a building built to an energy star baseline.

How warm is a Passive House?

Passive House buildings are designed to be comfortable all year round – cozy and

warm in winter (20°C)

, comfortably cool in summer (25°C).
