“…The use of a BIPV/T system to heat the air temperature around an ASHP's outdoor unit -namely the evaporator -can extend ASHP working hours and raise the COP, offering energy savings. Tardif et al (2017) showed that when combining a BIPV/T system with an ASHP, the total energy saving in heating was 41% compared to the base case. Li et al (2015) showed that when combined with a BIPV/T system, the COP of an ASHP could be increased from 3.72 to 4.6.…”

“…Energy systems are often augmented by supplementary electric or natural gas heating to improve system economics and meet design constraints [22,23]. Furthermore, thermal energy storage systems (e.g., floor concrete systems) in combination with geothermal, ground, or air source heat pumps are used to reduce a building's heating and cooling demands and to enhance the COP hp of heat pumps [22][23][24][25][26].…”

“…By energy modeling, another study found that use of an air-based PVT system alone does not provide any energy savings, while combining the PVT system with an air source heat pump results in 62% energy savings in comparison to an all-electric base case. Furthermore, the addition of thermal energy storage enhanced the performance of the system, mainly by addressing the time shift between a building's heating demand and solar energy availability [26]. Another study investigated the performance of an air source heat pump when configured using building-integrated solar thermal collectors and concrete slab or gravel bed thermal energy storage.…”

“…Among many, standard building energy modeling software include the Transient System (TRNSYS) simulation tool (http://www.trnsys.com/ (accessed 17 May 2021)), EnergyPlus (https://energyplus.net/ (accessed 17 May 2021)), and Integrated Environmental Solutions Virtual Environment (IESVE) (https://www.iesve.com/ (accessed 19 May 2021)) [1,2,26,28], which mainly focus on the integration of system-components with limited feedback interaction to outdoor conditions. Accounting for renewable and alternative energy options in standard building simulation tools poses limitations due to non-uniqueness and various objectives of system integration.…”

How Much Building Renewable Energy Is Enough? The Vertical City Weather Generator (VCWG v1.4.4)

A challenge in the integration of renewable and alternative energy systems for buildings is the determination of the renewable energy ratio, which involves the selection and sizing of appropriate building systems. To address this need, a micro climate-weather software titled the Vertical City Weather Generator (VCWG) is further developed to include renewable and alternative energy systems and account for full two-way interaction between the building system and outdoor environment. VCWG is forced to simulate performance of a residential building in Guelph, Canada, for an entire year in 2015. Various energy options are considered and further optimized for the building to reduce natural gas consumption, electricity consumption, and cost. On an annual basis using the global cost method, and compared to a building with no such renewable or alternative energy systems, the optimized system resulted in 80.3% savings in natural gas consumption, 73.4% savings in electricity consumption, and 3% savings is annualized cost. According to this analysis, some technologies, such as photovoltaics are more favorable in the Canadian climate than other technologies. It is suggested that the building optimization process is not unique, and it depends on background climate, optimization weighing factors, and assumptions used in the economic analysis, which require further research.

“…For a collector system, if the irradiance decreases and the flowrate through the system remains constant, the outlet temperature would decline and result in a lower COP. Furthermore, Tardif et. al (2017) found that over their study period, the fan power used to operate the BIPV/T coupled ASHP system greatly diminished their heating consumption savings largely due to the use of supplying a constant 30% of the HP's required air flow from the PVT; hence, the source temperature was low (close to the ambient).…”

Enhancements of a building integrated photovoltaic/thermal (BIPV/T) system intended for coupling with an air source multispeed heat pump (MSHP) is presented. The systems were analyzed using a modified version of EnergyPlus, a quasi-steady state building energy simulation program. A sensitivity analysis of the internal channel surface and cover emissivity parameters of the Opaque BIPV/T, transparent BIPV/T, and building integrated solar air heater collectors (BISAH) was conducted. In addition, collector arrangement analyses were performed. A BIPV/T- BISAH array design was selected based on the results of the analyses and evaluated using a net-zero energy house and an energy efficient house. The integrated BIPV/T-BISAH coupled ASHP system reduced space heating electricity consumption of the net-zero house by 6.5% and the energy efficient house by 3.4%. These low levels of savings were largely due to the passive design of the houses that reduced heating loads during sunny hours; this resulted in a mismatch between the hours when the integrated system could provide energy savings and the need for space heating.
