Notes on Building Health and Environmental Design

Introduction

  • Focus on strategies to improve lives of people inside buildings.
  • Discussing air quality and factors affecting it in our classroom.

Key Concepts of Green Buildings

  • Business Case for Green Buildings:
    • Tenants benefit more in green buildings than non-green buildings.
    • Benefits include:
      • Lower energy costs
      • Reduced environmental damages
      • Increased employee productivity, health, and comfort.
  • Market Dynamics:
    • Exploration of whether market conditions support these theories.
    • Different regions may have varying degrees of appreciation for green buildings.
  • Historical Context of Green Building Certification:
    • Early focus on energy saving in response to the 1970s energy crisis.
    • Increasing emphasis on health and well-being.
    • Expansion of certification standards to prioritize health post-COVID-19.

Health Impacts of Buildings

  • Studies on Sick Days and Health:
    • Research indicates healthier buildings correlate with fewer sick days.
    • Harvard School of Public Health is conducting relevant studies on the impact of buildings on human health.

Importance of Indoor Air Quality

  • Historical Issues:
    • Issues from the 1970s/80s led to "Sick Building Syndrome" due to poor air quality.
    • Lower ventilation rates historically used to save energy led to compromises in air quality.
  • Current Guidelines:
    • WHO data indicates high levels of air pollution leading to serious health risks.
    • Need for buildings to filter outdoor air effectively to reduce exposure pollutants (e.g., from transportation).

Environmental Threats to Health

  • Air Quality Monitoring:
    • Use of sensors to monitor air quality in real-time.
  • Temperature Control:
    • Buildings help manage heat exposure and cold discomfort.
  • Designing Healthy Buildings:
    • Concepts of building creating environments better than external conditions.
    • Importance of facilities promoting movement and air quality management.

Building Design Insights

  • Indoor Environment Factors:
    • Majority of time spent indoors affects temperature, light, and overall well-being.
    • Statistical Insight:
      • 5% population lives in unhealthy housing; the situation worsens in low-income renters.
  • Investment in Healthier Spaces:
    • Consideration of health implications of investment strategies for building technologies will yield significant returns.

Financial Implications of Building Health Investments

  • Healthcare Spending:
    • Healthcare spending in various countries is substantial, underlining the importance of healthy environments.
    • Costs associated with unhealthy workers and sick building syndrome can be significant.

The Role of Market Trends in Healthy Buildings

  • Investor Outlook:
    • Connection between employee health and corporate spending.
    • 10% of GDP in the U.S. is tied to healthcare, implicating large financial balance sheet impacts from health-determinant buildings.

Key Factors for Building Impact Assessment

  • Exposure and Concentration Understanding:
    • Importance of evaluating both exposure levels and harmful concentrations when assessing health benefits of building investment.
  • Conducting Studies:
    • Utilization of research techniques to observe impacts of ventilation and air quality on health, cognitive performance, and productivity.

Summary

  • Longitudinal studies can substantiate the connection between healthy buildings and lower healthcare costs, absenteeism, sustainability, rent pricing, and ultimately the overall market valuation.

Questions for Further Discussion

  • Insights into ventilation effects, lighting, ergonomics, and sustainable materials in building design.
  • Understanding market decisions regarding public and private sector adaptations to health-focused investments.
