Sustainability in Architecture

Carbon Emissions and Architecture
- Architecture accounts for approximately a third of carbon emissions.
- The design of buildings can contribute to energy efficiency without relying solely on air conditioning (AC).

Passive Heating Strategies

Importance of Orientation
- Buildings should be oriented on the site to maximize exposure to the sun.
- Identify cardinal directions significant for sunlight exposure, especially in climates like Indiana.
- The proper orientation helps manage passive heating effectively.
Cooling Strategy
- The first rule for cooling a building is to prevent it from getting hot in the first place.
Shading Strategies
- Various shading strategies were discussed to manage heat within buildings. Examples include:
- Utilizing thick, dense building materials that provide effective insulation.

Concept of Thermal Mass
- Thermal mass is an essential concept that describes the ability of materials (e.g., adobe, concrete) to absorb and retain heat.
- These materials absorb heat from sunlight during the day and release it slowly when temperatures drop, thus maintaining indoor comfort.
- Thermal mass performs best in arid climates where there are significant temperature differences between day and night.
- Heat Movement
- Heat within thermal mass moves towards cooler areas, meaning the heat absorbed on one side of a wall eventually flows out.
Design Strategies
- High ceilings and increased exterior surface area enhance air circulation and cross-ventilation in buildings.
- Effective strategies may lead to lower reliance on mechanical ventilation.

Definition and Importance
- Adaptive reuse involves repurposing existing buildings for new uses rather than demolishing them.
- This strategy is significantly impactful for sustainable architecture by preserving resources and minimizing waste.

Definition
- Biophilic design incorporates natural elements to enhance well-being and connection
