There are several commonly employed research methods to study the environmental impact of architectural designs. Some of them include:
1. Life Cycle Assessment (LCA): LCA is a commonly used method to assess the environmental impacts of a building throughout its entire life cycle, from raw material extraction to construction, use, and end-of-life. It considers factors such as energy consumption, water usage, material choices, and emissions.
2. Energy Modeling and Simulation: Energy modeling uses computer simulations to assess the energy performance and efficiency of a building design. It helps to evaluate factors like heating and cooling loads, energy consumption, and potential for renewable energy integration.
3. Carbon Footprint Analysis: This method is used to quantify the amount of greenhouse gas emissions produced by the entire life cycle of a building. It considers emissions from materials, construction, operation, and disposal.
4. Daylight and Sunlight Analysis: Daylight and sunlight analysis assess the natural light conditions within a building or its surroundings. These studies evaluate factors such as daylight availability, solar radiation, glare, and shading to optimize natural lighting and reduce the need for artificial lighting.
5. Water Efficiency Analysis: Water efficiency analysis evaluates the water usage and management strategies of a building design. It considers factors like rainwater harvesting, wastewater recycling, water-efficient fixtures, and landscaping strategies to reduce water consumption.
6. Environmental performance simulation software: Various software tools exist to simulate and forecast environmental impacts, energy usage, thermal performance, and occupant comfort in architectural design. These tools use algorithms and data inputs to compute and assess environmental indicators.
7. Material Selection and Sustainability Assessment: This method involves evaluating the environmental impact of construction materials, including their extraction, manufacturing, transportation, and disposal. It considers factors such as embodied energy, carbon footprint, recyclability, and toxicity to guide sustainable material choices.
8. Post-occupancy evaluation: Post-occupancy evaluations involve studying the actual performance of a building design after its construction. It includes monitoring energy consumption, user comfort, indoor air quality, and other environmental parameters to assess the design's effectiveness and identify areas for improvement.
These research methods are often used in combination to provide a comprehensive understanding of the environmental impact of architectural designs at different stages of a building's life cycle.
