In Part 2, we continue our exploration of resiliency in architecture with Sadaf Jafari, Director of Sustainability at SGA, an architecture and design firm with offices in Boston and New York, that specializes in innovative and sustainable solutions for complex urban and waterfront environments.
Jafari provides insight into how SGA’s approach to climate adaptability emphasizes proactive solutions and innovative design techniques, from conducting thorough climate risk assessments to implementing regenerative design principles.
Q: How should design teams approach the challenge of integrating climate change projections, such as rising flood plains and temperature fluctuations, into the planning and construction of new buildings?
Design teams should approach the integration of climate change projections into building planning and construction with a multifaceted and proactive strategy. Some key steps are:
- Climate risk assessment; gather and analyze location-specific climate data, developing climate scenarios for potential impacts.
- Conduct a site selection and analysis to avoid high-risk areas for flooding and extreme weather. This should include studying topography and hydrology for water movement for the medium risk sites that they would be chosen for construction.
- Practice resilient design strategies to elevate structures in flood-prone areas. Use durable materials and construction methods, incorporating passive design for natural temperature regulation and advanced stormwater management systems and build flood defenses. Designers should also prioritize flexible and adaptive design. Modular systems, for example, offer easy upgrades and ensure infrastructure can accommodate future changes.
- Urban planning strategies can be utilized to reduce waste heat and greenhouse gas emissions through designs that promote transit access and walkability. Additionally, enhancing resilience by modifying urban layouts and increasing vegetative cover.
- Finally, it’s essential to have early investment in resilience. These strategies must never be an afterthought but must be incorporated from the beginning of the planning process.
Q: What specific considerations are crucial for designing buildings that can withstand regional climate variations, such as droughts, heat waves, and increased flooding? How can architects balance these factors across different geographic locations?
Designing buildings to withstand regional climate variations involves crucial considerations such as water-efficient systems and rainwater harvesting, drought-tolerant landscaping, enhanced insulation, natural ventilation, shading, structure elevations, use of flood-resistant materials, effective drainage and stormwater management systems. The core goal is to make your building as regenerative as possible.
Architects can balance these factors across different geographic locations by tailoring strategies to specific climate risks, using local climate data and applying universal principles of energy efficiency and durability. For example, areas in New England and the Northeast are more concerned with flooding and mitigating the risks of rising flood plains, while California prioritizes water conservation efforts. Collaboration with multidisciplinary teams and adhering to local building codes and sustainability standards are also essential.
Q: How does thorough dew point analysis contribute to preventing insulation issues and ensuring the long-term durability of buildings in varying climates? Can you provide examples of how this analysis has influenced your design projects?
Dew point analysis affects the type and amount of insulation, the placement of the vapor barrier, and even the window performance rating needed for the project.
Addressing dew point analysis in the design phase ensures that insulation remains effective, prevents moisture-related issues, and contributes to building longevity. Architects integrate this analysis into their designs to create resilient, energy-efficient structures.
Q: What are some effective stormwater management strategies that can be integrated into building designs to mitigate flooding risks, especially in areas like New England that are prone to heavy rainfall and storms?
Effective stormwater management strategies are crucial for mitigating flooding risks, especially in regions like New England, which experience heavy rainfall and storms. Some key approaches we integrate into building designs include:
- Low Impact Development (LID): Uses decentralized techniques to manage rainfall at the source.
- Preserving Natural Features: Protects existing landscapes to maintain natural water absorption.
- Minimizing Impervious Surfaces: Reduces surfaces like concrete to allow more water infiltration.
- Bioretention and Rain Gardens: Captures and treats runoff through landscaped depressions.
- Permeable Pavements: Allows water to infiltrate, reducing surface runoff.
- Green Roofs: Absorbs rainfall and reduces runoff.
- Rainwater Harvesting: Collects and stores rainwater for non-potable uses.
- Native Landscaping: Uses plants with deep roots to absorb and filter stormwater.
- Constructed Wetlands: Mimics natural wetlands to filter and absorb stormwater.
These features help absorb and slow down stormwater runoff, reducing pressure on drainage systems and minimizing flood risks during heavy rainfall and storms.
Q: How do you incorporate future climate models and projections into your design process to ensure buildings are not only fit for current conditions but also adaptable to potential changes over the next 20-50 years?
We incorporate future climate models and projections into our design process to ensure buildings are resilient to potential changes. But our main goal is to design buildings that are adaptable to potential changes over the next 600 years, not 20-50 years and that is why SGA is trying to address principles of Regenerative Design. This model encourages that design should mimic nature, which heals itself and regenerates.
Regenerative Design gives back to the grid and allows developers, architects, and project owners to achieve climate goals. It requires a mindset shift. Regenerative Design recognizes that even today’s best-case scenarios leave tremendous room for improvement and energy savings.
Another trend we’re seeing is more utilization of the Passive House model, a certification with PHIUS (Passive House Institute US Certified) that outlines a set of design principles used to attain a quantifiable and rigorous level of energy efficiency within a specific comfort level. Using this model, energy efficiency stems from continuous insulation throughout an airtight building envelope, high-performance windows, balanced heat- and moisture-recovery ventilation, management of solar gain, and elimination of thermal bridging. SGA designed the first “Passive Building” residence hall In Massachusetts at Wheaton College, successfully cutting operating costs by 50%. We also designed Williams College’s Garfield House in Williamstown, MA, a 40-bed suite-style residence hall, to meet the strict PHIUS criteria, implementing passive ventilation and phase change materials for cooling such as enhanced wood framing and structural insulated panel systems.
Q: What are the key elements of resilient design that you prioritize to ensure buildings can endure and recover from catastrophic weather events? How do these elements contribute to long-term sustainability and community resilience?
To ensure buildings can endure and recover from catastrophic weather events, several key elements of resilient design must be prioritized. These elements contribute significantly to long-term sustainability and community resilience:
- Robust Structural Systems: Withstand extreme weather events.
- Climate-Adaptive Building Envelope: Protects against weather extremes.
- Resilient Infrastructure and Utilities: Keeps critical systems functional during disasters.
- Adaptive Design Strategies: Flexible designs that adapt to changing conditions.
- Community Engagement and Preparedness: Involves the community in planning and preparedness.
- Integration of Green and Sustainable Practices: Reduces environmental impact and enhances independent operation during crises.
These elements contribute to sustainability by reducing environmental impact, improving energy efficiency, and conserving resources. They build community resilience by ensuring essential infrastructure remains operational during disasters and by fostering community unity and preparedness. Resilient design not only protects buildings from severe weather but also strengthens the well-being and resilience of local communities, ensuring they can recover and thrive in the face of adversity.
Q: How can architects and design firms effectively collaborate with clients and stakeholders to incorporate resiliency and climate adaptability into projects from the outset? What best practices have you found to be most successful in these collaborations?
