Passive Design

Energy efficient house

A passive house will keep warm for a long period of time without having to consistently put on the heating.

Concept ? The idea of a passive house is to ? Maximise heat gain and minimise heat loss

Subtopic

Comfortable environment

We do not want to rely on FOSSIL fuels to heat the house

Active Heating = Oil boilers or heating systems that are not renewable.

Key Principles of passive design

Compact form

Airtightness

MVHR

Super Insulation

Solar Gain/Heat Gain

Preventing Thermal Bridging

Thermal Mass

Energy efficiency

Reduction in heating and cooling loads

Lower energy consumption

Comfort and well-being

Improved thermal comfort

Enhanced natural lighting

Better indoor air quality

Cost savings

Decreased energy bills

Potential for government incentives and rebates

Orientation and layout

Taking advantage of solar angles

Minimizing exposure to prevailing winds

Insulation and thermal mass

Proper insulation materials and installation

Utilizing thermal mass for heat storage

Natural ventilation

Cross-ventilation through strategic window placement

Utilizing stack effect for airflow

Daylighting

Incorporating skylights and light shelves

Using reflective surfaces to maximize natural light

Shading and sun control

Designing overhangs and awnings

Implementing shading devices such as blinds or curtains

Residential buildings

Example 1: Passive solar house in a cold climate

Use of south-facing windows for solar heat gain

Insulated foundation and walls

Example 2: Passive cooling strategies in a hot climate

Ventilation through building orientation and natural airflow

Use of shading devices to reduce solar heat gain

Commercial buildings

Example 1: Passive design in an office building

Daylighting strategies to reduce artificial lighting use

Insulation and thermal mass for temperature control

Example 2: Passive design in a shopping center

Efficient HVAC systems and natural ventilation
