LEED (Leadership in Energy and Environmental Design) is a certification program for quantitatively assessing the qualifications of homes, non-residential buildings, or neighborhoods terms sustainability. supported by U.S. Green Building Council (USGBC), nonprofit membership-based organization. Worldwide, thousands projects received one four levels certification. One five rating systems (or specialties) covered Design Construction (BD + C), representing buildings. This system further divided into eight adaptations. The adaptation (New Major Renovation) NC applies to newly constructed as well those going through major renovation. has six credit categories, addition three minor ones. nine categories together have total 110 attainable points. Atmosphere (EA) category dominant adaptation, with 33 points under it. important addresses topics commissioning, energy consumption records, efficiency, use refrigerants, utilization onsite offsite renewable energy, real-time electric load management. study aims highlight some differences EA BD C:NC it evolved from version 4 (LEED v4, 2013) 4.1 v4.1, 2019). For example, updated includes metric greenhouse gas reduction. Also, no longer permits hydrochlorofluorocarbon (HFC) refrigerants new heating, ventilating, air-conditioning, refrigeration (HVAC & R). In addition, classifies tiers, differentiating between onsite, new-asset offsite, old-asset types.

The development of porous materials exhibiting steep and stepwise adsorption water vapor at desired humidity is crucial for implementing diverse applications such as control, heat allocation, atmospheric harvesting. precise molecular-level elucidation structural characteristics chemical components that dictate the sorption behaviors in confined nanospaces, metal-organic frameworks (MOFs) particular, fundamentally important, but this has yet to be largely explored. In work, by leveraging isoreticular principle, we crafted two pairs isostructural Zr-MOFs with linker backbones benzene pyrazine acting hydrogen-bonding donor acceptor, respectively. outstanding cyclic durability four permits persuasive investigation correlation inflection point steepness (the central figures-of-merit sorption) functionality. pyrazine-carrying both show uptake lower relative pressure slightly decreased steepness, which are quantitatively described Dubinin-Astakhov relation. We deciphered privileged clusters through single-crystal X-ray diffraction studies moiety formed stronger interactions guest molecules favored formation pentamers instead hexamers observed analog. donor/acceptor manipulation approach presented work may facilitate future research endeavors focusing on molecular attribute engineering predeterminedly ultrawater-resistant MOF platforms efficient regulation toward customized applications.
