A numerical model of a solar wall (SW) with transparent insulation (TI) is proposed in this article. The model is based on the finite-difference method and thermal conductivity equation, with a heat source term for the absorber. Using this model, the energy efficiency of a solar wall with transparent insulation (SW-TI) with honeycomb insulation made of modified cellulose acetate was analyzed in the case of different climatic conditions prevailing in Poland, different orientations of the envelope, and different insulation thicknesses. Simulations were carried out throughout the whole heating period. Monthly energy balances and temperature distributions for the analyzed envelopes at individual moments of the heating period are the basic results of the simulations. It was found that the use of 108 and 88 mm thick insulation was the most recommended in the considered temperate climate. Placing transparent insulation on a wall with an eastern or western orientation caused the annual heat balance of the envelope to decrease by 24–31% in relation to the value of this balance in the case of a southern orientation. The monthly heat balances obtained using the proposed model give results consistent with the method of calculating heat gains for opaque building envelopes with transparent insulation included in the PN-EN ISO 13790:2008 standard.

The building sector in Malaysia consumes up to half of the electricity generated in the country. Therefore, there are needs to have a continuous effort to promote microalgae as part of an innovative building envelope system. This paper intends to investigate the potentiality of implementing the microalgae photobioreactor (PBR) in building envelopes in Malaysia. The findings from the precedent studies are synthesised into ten (10) parameters and translated into four (4) design modules. In conclusion, the suggested parameters are crucial in establishing microalgae photobioreactor (PBR) as a suitable prospect for energy efficiency in building envelopes in the tropical climate.
