Lavasan House Inside: A Revolution in Sustainable Architecture & Eco-Friendly Homes

8.1 Passive Solar Design & Daylighting

One of the key sustainability principles is harnessing natural light and heat, which is particularly challenging but essential for underground homes. Strategies include:

• Strategic Site Orientation: Positioning windows, skylights, and light wells to maximize solar gain during winter, while minimizing overheating in summer.
• Light Tubes & Solar Skylights: Using reflective tubes or glass skylights to channel sunlight deep into interior spaces, reducing artificial lighting needs.
• Light-Colored Interiors & Reflective Surfaces: Enhancing interior brightness and diffuse natural light.

8.2 Ventilation & Indoor Air Quality

Ensuring good air quality requires:

• Natural Ventilation Pathways: Designing operable windows, vents, and air wells that utilize stack effect and wind pressure.
• Mechanical Ventilation with Heat Recovery (MVHR): Systems that supply fresh air while reclaiming heat, conserving energy.
• Air Purification Systems: Incorporating filters that remove pollutants, allergens, and moisture.

8.3 Thermal Regulation & Insulation

Earth’s thermal mass offers passive cooling and heating, but additional measures include:

• High-Performance Insulation: Using eco-friendly insulation materials such as cellulose, sheep’s wool, or aerogel-based options.
• Thermal Breaks: Implementing design features that prevent heat transfer through structural elements.
• Phase Change Materials (PCMs): Incorporating materials that absorb or release heat as they change phase, stabilizing indoor temperatures.

8.4 Green Roofs & Living Walls

Integrating vegetation on accessible roof areas or walls can:

• Improve insulation
• Reduce heat island effects
• Promote biodiversity
• Enhance aesthetics and mental health
