Introduction: Thermal comfort is a crucial factor in the design and operation of buildings, as it directly affects the well-being and productivity of occupants. To ensure optimal thermal comfort, various standards and guidelines have been developed, and one widely recognized standard is ASHRAE 55. ASHRAE 55 is a widely used Read more…
Introduction: Acoustic comfort, or the quality of the acoustic environment within a building, is a crucial factor that impacts the comfort and well-being of occupants. Unwanted noise can lead to annoyance, stress, reduced productivity, and even health issues, while a well-designed acoustic environment can contribute to a sense of calm, Read more…
“While gravity energy storage technology is still in the early stages of development and no commercial-scale projects exist, the potential for large-scale, low-cost energy storage using this technology is immense.” Gravity energy storage (GES) is an emerging technology that has the potential to revolutionize the energy storage landscape. GES relies Read more…
LEED (Leadership in Energy and Environmental Design) certification is an internationally recognized green building rating system. One of the LEED EBOM (Existing Buildings: Operations and Maintenance) credits that buildings can earn is the SUSTAINABLE SITE Credit: Rainwater Management. This credit is intended to reduce the volume of runoff and improve Read more…
Solar Heat Gain Coefficient (SHGC) is the amount of solar radiation that transmits through a window in the form of heat via three forms of thermodynamic heat transfer, i.e., conduction, convection, and radiation. the coefficient is expressed as a value between 0 and 1. the lower the SHGC, the lower Read more…
The VCS VM0018 methodology, also known as the “Energy Efficiency and Fuel Switching Project Protocol”, provides a standardized approach to quantify and verify GHG emissions reductions from energy efficiency and fuel switching projects. This methodology is applicable to a wide range of sectors, including buildings and waste management programs. In Read more…
Solid waste management is a crucial aspect of modern urban living. As cities continue to grow, the amount of waste generated also increases, leading to a significant environmental impact. Solid waste management also presents an opportunity to reduce greenhouse gas (GHG) emissions through the implementation of carbon credit projects. In Read more…
The TRUE Advisor Examination is a professional certification program for individuals working in the green building industry. The program is administered by GBCI (Green Business Certification Inc.), the same organization that administers the LEED (Leadership in Energy and Environmental Design) certification program. TRUE (Total Resource Use and Efficiency) is a Read more…
Water is a valuable resource that must be preserved and managed efficiently, especially in buildings. The Leadership in Energy and Environmental Design (LEED) program developed by the U.S. Green Building Council (USGBC) includes a Water Performance prerequisite for existing buildings (O+M) and interiors. The intent of this prerequisite is to Read more…
The Energy and Atmosphere Prerequisite for LEED Existing building (O+M) is designed to promote continuity of information to ensure that energy-efficient operating strategies are maintained and provide a foundation for training and system analysis. This prerequisite applies to O+M: Existing Buildings and O+M: Interiors. To meet this prerequisite, building owners Read more…
