Effect of Sky Discretization for Shading Device Calculation on Building Energy Performance Simulations [PDF]

, 2020
The calculation of sunlit surfaces in a building has always been a relevant aspect in building energy simulation programs. Due to the high computational cost, some programs use algorithms for shading calculation for certain solar positions after ...

Small-scale human-biometeorological impacts of shading by a large tree

Open Geosciences, 2016
This study provides evidences on the beneficial small-scale human-biometeorological effects of a large shade tree during the daytime in summer. We carried out detailed measurement from 10 am to 6 pm with two human-biometeorological stations on a popular ...

Agrivoltaic System and Modelling Simulation: A Case Study of Soybean (Glycine max L.) in Italy

Horticulturae, 2022
Agrivoltaic systems (AV) combine agricultural activities with the production of electricity from photovoltaic (PV) panels on the same land area. The concept of AV systems was introduced in 1982 by Goetzberger and Zastrow, but only more recently have the ...

Growth and Leaf Gas Exchange Upregulation by Elevated [CO₂] Is Light Dependent in Coffee Plants

Plants, 2023
Coffee (Coffea arabica L.) plants have been assorted as highly suitable to growth at elevated [CO2] (eCa), although such suitability is hypothesized to decrease under severe shade.

Optimal design of photovoltaic shading systems for multi-story buildings [PDF]

, 2019
This study provides new insights into the comprehensive energy and economic performances of photovoltaic shading systems (PVSS) in multi-story buildings. A numerical shading model was developed to evaluate the shading effect from an upper PVSS row on its

Towards Grower-friendly Apple Crop Thinning by Tree Shading [PDF]

, 2008
Light management with shading nets, which reduce sunlight by 74%, might be an alternative to chemicals commonly used for thinning on apple trees. To study the effect of shading on crop load and fruit quality, trials were conducted in field experiments ...

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
