“…In the work of Rosso et al [98], TiO 2 pigments were added as IR pigments since they are almost white, enhancing thermal-optical characteristics and "coolness". Cool pigments may mitigate urban heat islands [98], increase reflection and reduce energy consumption [99] and could be further obtained by combining iron oxide with TiO 2 [100].…”

Building envelopes coated with TiO2-based mortars benefit from depolluting, antibiological and self-cleaning effects. Therefore, photocatalytic renders are allies in the quest for sustainability in the built environment, potentially combatting atmospheric pollution, enhancing durability and reducing maintenance needs. Surface finishing characteristics of the renders influence their photocatalytic efficiency and esthetic and functional properties. In this context, this study reviews the existing literature, focusing on proven surface-affecting parameters, the surface and color of TiO2-based mortars, to explore their impacts on photoactive behavior. The incorporation of TiO2 within an additional surface layer and its mixture into the mortar in bulk were observed for surface roughness. Mainly the addition of TiO2 during casting was identified in colored mortars. Generally, a moderate surface roughness led to better photoactivity; microroughness affected self-cleaning by facilitating dirt deposition. The interaction between the surface roughness and the photocatalytic layer affected the water contact angle, regarding superhydrophilicity or superhydrophobicity. The photoactivity of colored mortars with TiO2 depended on the color and amount of the added pigments, which influenced electron–hole recombination, physically occupied active sites or, on the other hand, led to a higher formation of reactive radicals. Surface finishing can thus be designed to enhance the photoactivity of TiO2-based mortars, which is fundamental for current climate concerns and emphasizes the need for life cycle assessments and environmental protection.

This paper assesses the separate and simultaneous effects of utilizing cool paints (CPs) and phase change materials (PCMs) in the building envelope of high‐rise office buildings on energy demand. Dynamic building energy simulations are used to investigate these impacts. CPs are known to scatter solar radiation, while PCMs are utilized for thermal energy storage in the building envelope. The effects of three CPs with constant thickness and place of application and three PCMs with varying thicknesses on the inner and outer layers of external walls are investigated, resulting in a total of three and twelve conditions for CPs and PCMs, respectively. Additionally, the study considers 36 modes of the combined use of CPs and PCMs. The study envisages that applying a combination of white CP with ATP23 PCM in the inner layer of external walls reduces 10.11 kW·hr/m2·year energy demand in the building (6.49% and 1.29% decrease in gas and electricity demand, respectively). While CPs are most effective in reducing energy demand during hot seasons, PCMs can provide benefits year‐round. The economic analysis elucidates that the implementation of white CP yields a payback period of 3 years and an internal rate of return of 55% in the second scenario.
