“…Many literatures reported that in commercial building, air conditioning systems account almost half of the total power consumption, and being the single biggest consumers [1][2][3][4][5][6]. It is also found that another building consumes more than 50%-70% for HVAC (Heating, Ventilating, and Air Conditioning) of total electrical energy use [7][8][9]. Therefore, their efficiencies has a significant effect on the overall energy performance of these buildings.…”

Split air conditioning systems produce reasonable amount of condensate which is usually not utilized and thrown away to the environment. On the other hand, it consumes a lot of energy during operation. The aim of this study is to investigate the improvement of air conditioning systems performance utilizing condensate. A direct evaporative cooling using condensate is incorporated on a 0.74 ton-cooling capacity of split air conditioning to decrease the air temperature before entering the condenser. Performances of the split air conditioning with and without direct evaporative cooling are compared and presented in this paper. The results show that the use of direct evaporative cooling using condensate into the air before passing through the condenser reduces the compressor discharge pressure. The decrease of the condenser pressure led to 4.7% and 7% reduction of power consumption for air conditioner without cooling load and air conditioner with 2000 W cooling load, respectively. The cooling effect and coefficient of performance (COP) increase with the decrease of compressor power. The use of direct evaporative cooling with condensate into the air before entering the condensing system can enhance the system performance and protect the environment.

“…However, an hourly analysis of the energy performance indicated that there is a mismatch between energy demand and supply. To reduce the energy deficit in Cameroon, a rooftop BIPV system was analyzed considering a daily energy need of 3 kW . It was found that the primary energy consumption can be reduced with the technology by about 66 kWh/m 2 .…”

The integration of solar energy systems into buildings via photovoltaic (PV) and other technologies can curb the amount of greenhouse gas emissions produced by buildings. However, the performance of solar energy systems is highly dependent on climatic and economic conditions. In this regard, the techno‐economic feasibility of building attached PV systems are studied for three scenarios considering three cities of Iran namely Tehran, Tabriz, and Kish Island, which have different climatic conditions. The result shows that the PV systems can annually meet 4.5–20% of the electricity needs for Tehran, 3.0–13% for Tabriz and 2.0–11.5% for Kish Island. Moreover, roof mounted PV systems were found to be a better alternative to envelope attached systems in technical and economic terms. The payback period for the solar energy systems was found to be between 8.7 and 14.3 years for Tehran, 14.2 and 22.6 years for Tabriz, and 11.6 and 21.1 for Kish Island.

“…The definition generally accepted for BIPV, is contextualising the definition by the product's power generation abilities and impact on the building's integrity if the BIPV product was removed. In contrast, traditional rack mounted modules are not integral to the building's infrastructure and can be removed with minimal impact [4], [5]. BIPV products are considered a functional part of the building structure, or architecturally integrated into the building's design.…”

Assessing the potential of steel as a substrate for building integrated photovoltaic applications

Government edicts and national time bound policy directives are shaping the drive toward cost effective renewables such as photovoltaics (PV). Building Integrated Photovoltaics (BIPV) has the potential to provide significant energy generation by utilising the existing building infrastructure as a power generator, engendering a transformation shift from traditional energy sources. This research presents an innovative study on the industrial viability of utilising "rough" low carbon steel integrated with an Intermediate Layer (IL) to develop lower cost thin film BIPV products and is compared to existing commercial products. Consideration of the final product cost is given and potential business models to enter the BIPV are identified. The lab scale and upscaling elements of the research support the significant benefits of an approach that extends beyond the use of expensive solar grade steel. A stateof-the-art review of existing steel-based BIPV products is given and used as a benchmark to compare the new products. The results demonstrate that a competitively commercial product is viable and also highlight the strong potential for the adoption of a "rough" steel + IL focused approach to BIPV manufacture and a potential new direction to develop cost efficiencies in an increasingly competitive market.
