Can hollow-core slab buildings be equipped with photovoltaic power generation

A self-compacting concrete hollow slab solar pavement with micro photovoltaic can satisfy both traffic and power generation functions array was proposed; The finite element numerical simulation and power generation simulation of the pavement structure were carried out;.

Chen et al. [11] designed and modeled a building integrated photovoltaic/thermal (BIPV/T) system in a near zero energy building in cold climate of Canada. Accordingly, they have studied the effect of integrating a ventilated concrete slab (VCS) with BIPV/T system as an active TES system.

The analysis on this building operation data pointed out that an active hollow core slab-based building could be able to attain an energy target of between 50 and 70 kW h/m 2 per year with more efficient fans, better control and improved night heating, depending on the heat gains, heat loss characteristics and local weather.

The results show that the developed hollow slab of solar pavement based on light-guide concrete has high strength, and its working voltage and maximum output power increase with the increase.

The mechanical properties and the power generation efficiencies were tested for the model. The results show that the developed hollow slab of solar pavement based on light-

6 FAQs about [Can hollow-core slab buildings be equipped with photovoltaic power generation ]

How much energy does a hollow core slab based building produce?

Can a hollow core concrete slab save energy?

The results indicated that with respect to the conventional design, this system could provide energy savings of about 13% and a reduction of 30% in the peak cooling load. In a technical book by Croome and Robert , the hollow core concrete slab is introduced.

Can active hollow core slab be used for ventilation?

A review on the development and modeling of active hollow core slab is presented. The applications and performance evaluation of the slab in building are reviewed. Finite element or finite difference method is often used in multidimensional model. Performance evaluations of building using active slabs for ventilation are limited.

What is the cooling potential of active hollow core slabs?

In the like Sweden or Finland climate conditions, the cooling potential of using active hollow core slabs may be 10–50 W/m 2 depending on the ventilation air flow rates in the core slab. The measurements in a real building using active slabs as building structures in South Africa shows that the cooling load was reduced by about 50 W/m 2.

Why is a hollow core slab important for building system design?

Accurate models for the thermal behaviors in the hollow core slab is significantly important for the building system design using this slab for leveling indoor environment and development of the operation strategy for exerting the sufficient benefits of the hollow core slab for energy saving and indoor thermal comfort.

What is active hollow core slab?

For uniform description in this study, it is called “active hollow core slab” or “active slab” with hollow cores in the slab for air passage since ventilation in the core needs fans for transportation, and the ventilation has heat exchange with the slab. 2. Principle of hollow core slabs for air conditioning in building systems
