LEED Green Associate and ASHRAE Standards: Energy, Atmosphere, and Indoor Environmental Quality in USGBC LEED
In the realm of sustainable building design, the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) plays a significant role. This organisation develops standards related to building systems, energy efficiency, indoor air quality, refrigeration, and sustainability.
When it comes to the Leadership in Energy and Environmental Design (LEED) certification programme, ASHRAE standards are particularly influential in three key categories: Energy and Atmosphere (EA), Indoor Environmental Quality (IEQ), and Water Efficiency.
The Energy and Atmosphere category is designed to address energy performance, efficiency, and the incorporation of renewable energy sources. It aligns with ASHRAE Standard 90.1 and 62.1, which focus on energy efficiency and ventilation, respectively. The primary objective of this category is to reduce energy consumption and greenhouse gas emissions.
On the other hand, the Indoor Environmental Quality (IEQ) category aims to create healthy, comfortable, and productive indoor environments for building occupants. This category focuses on four main areas: indoor air quality, thermal comfort, lighting quality, and acoustic performance. ASHRAE Standards 55, 62.1, and 52.2 are particularly relevant here, as they cover thermal comfort, ventilation, and air filter performance and efficiency, respectively.
While the Sustainable Sites and Materials and Resources LEED categories do not rely as heavily on ASHRAE standards and guidance compared to the EA and IEQ categories, they still play a role, particularly in terms of energy efficiency and indoor air quality.
For those preparing for the USGBC LEED Green Associate exam, practice questions and answers are available for free, aiding in passing the exam and earning certification.
It's also worth noting that ASHRAE Standard 189.1 is particularly relevant for high-performance green buildings. This standard provides minimum requirements for the design of high-performance green buildings, ensuring they are energy-efficient, healthy, and sustainable.
In conclusion, ASHRAE's standards play a crucial role in shaping the LEED certification programme, particularly in the Energy and Atmosphere and Indoor Environmental Quality categories. By focusing on energy efficiency, indoor air quality, and overall sustainability, these standards help to create buildings that are not only environmentally friendly but also beneficial for the health and wellbeing of their occupants.
