Socio-economic assessment of rainwater harvesting systems considered as one of the efficient approaches in water resource management under deficit conditions, leads to a better management practice in the implementation of such systems. This work was aimed at analyzing the socio-economic limitations and potentials of rooftop catchment systems in Golestan province. The methodology was based on fi...

The world has a long experience of using harvested rainwater from rooftop catchments in urbanized regions. There are also many studies about the technical, health, and environmental details of such systems. The gradual prevalence of rainwater harvesting systems in the country exposes a necessity to determine and define some guidelines and instructions for health and environmental considerations...

The global freshwater and energy crisis have prompted worldwide investments in rainwater harvesting and solar energy systems. As the implementation of these two systems develops concurrently, they can easily become integrated into one rooftop structure. Photovoltaic systems have the potential to leach heavy metals and other toxins from newly installed, broken or aged modules. Since the type of ...

The retail price a household pays for the last unit of grid-supplied electricity consumed is an important driver of the decision to install a rooftop solar photovoltaic (PV) system. This price is the cost a household avoids by consuming a kilowatt-hour (KWh) from their rooftop solar system. Consequently, if the levelized cost of a KWh from a rooftop solar system is less than this retail price, ...

Make your home solar is going to be reality within few years. Rooftop PV has been developed by Germany, Spain and Italy with the encouragement Feedin -Tariff system for early attaining towards grid parity. The rates of solar PV has been drastically reduced in recent years and approaching towards the grid parity. There has been increasing trend of grid connected residential rooftop PV worldwide ...

The benefits of rooftop greening are ascertained in thermal perspective. It effectively reduces the near surface ambient temperature and the reflected irradiation from the rooftop slab, thus increasing the thermal comfort environment above the lawn and reduces the heat transferred through the rooftop slab. The former effect enables the potential usage of the rooftop spaces for human activity an...

We present an approach for detecting and describing complex buildings with flat or complex rooftops by using multiple, overlapping images of the scene. We find 3-D rooftop boundary hypotheses from the line and junction features of the images by applying consecutive grouping procedures. First, 3-D features are generated by grouping image features over multiple images, and rooftop hypotheses are ...

This paper presents a novel approach for extraction of rooftops in satellite/aerial imageries. This method is semiautomatic in which a point inside each rooftop must be identified by the user. The method utilizes corners and star algorithm to generate a set of rooftop outlines that are assessed and refined through an energy minimization process. The energy of each rooftop candidate is computed ...
