BUILDING FABRIC

The talk focuses on the crucial role of building fabric, also known as the building envelope, which remains relatively constant over time but holds immense influence over a building's comfort systems. This envelope acts as a shield against external weather conditions and microclimates, encompassing factors like solar radiation, wind, precipitation, temperature, and humidity. As our climate undergoes shifts, the quality of the building fabric becomes even more vital. It has the potential to greatly reduce the reliance on heating, cooling, lighting, and ventilation systems, effectively minimizing energy consumption and carbon footprint. Essential elements for designing in response to climate changes include weather protection, insulation, air tightness, and moisture management. Moreover, design choices should incorporate aesthetics, accessibility, and materials.

  • Options like sealed and permeable systems exist for effective weather protection. 

  • Insulation is a cornerstone consideration, recommending thicker insulation for colder climates and strategies like the passive house standard for comprehensive energy efficiency. 

  • Airtightness is paramount in temperate and cold climates to prevent heat loss, while a balanced ventilation system ensures optimal indoor air quality. Managing internal moisture is equally vital to avert issues like mold growth and material deterioration. 

  • Incorporating thermal mass, whether structural or non-structural, can enhance a building's capacity to absorb and release heat.
