“…Additionally, it identified the optimal level at which the minimum life cycle energy demand was achieved. On the other hand, Fosas et al [34] presented a simple-to-use model, ZEBRA, aiming to scope zero-carbon buildings in the beginning stage of design. With 33 inputs from the user, the model yields results for both embodied and operational carbon.…”

The establishment of net-zero-energy and net-zero-carbon buildings can offer significant opportunities to reduce environmental impact in the building sector. Several successful net-zero-energy buildings highlight the feasibility of reducing energy consumption via energy-efficient strategies and the use of renewable energy technologies. To comprehend the existing innovatory designs, techniques, and practices employed to achieve net-zero-energy buildings, this research aims to review the up-to-date advancements in net-zero-energy building practices. The utilization of embodied carbon assessments to achieve the net-zero status of buildings is explored. The findings indicate an escalating global interest and participation in the field of study, and reveal three major areas related to net-zero-energy buildings: multidisciplinary approaches, energy systems, and guidance, which together cover thirteen subfields. The role of life cycle assessment in buildings is emphasized, offering insights into the role of embodied emissions relative to operational emissions over the entire life cycle of a building. In the end, possible future study directions are outlined, including balancing energy efficiency with sustainability, and assessing the impact of design on emissions and economic outcomes. These areas collectively contribute to transforming sustainable building concepts into reality.

“…(Approach 1:) The most common method minimizing building energy demand is to enhance thermal performance of building envelopes or adopting HVAC system with higher energy efficiency [16]. Increasing thermal resistance through insulation [17] [18], enhancing thermal stability through PCM [19], are common and effective means for lowering thermal load of buildings as passive design. And some active technologies [20] such as thermoelectric wall [21], or water flow window [22], are also contributing novel solutions for NZEBs.…”

“…With a primary pedagogical purpose, this tool needs approximately 33 inputs to generate a reliable building model. Among its drawbacks, the options for energy efficiency measures are limited; for example, implementing phase change materials in the envelope is not available, and energy generation is only calculated by photovoltaic systems [21]. In Mexico, there are two building assessment tools developed in relation to energy performance.…”

There is a need for stakeholders in the construction sector to evaluate energy efficiency and renewable energy generation alternatives appliable to buildings at early design stages. In this regard, public and private organizations have developed tools to compare different options. It was observed that when the objective was to create nearly Zero Energy Buildings (nZEB), the number of tools was still scarce. With this aim, this work presents a new, free digital tool that can predict, among others, energy consumption, energy generation, emissions savings, and payback time. For this purpose, different alternatives applicable to the roof, such as phase change material (PCM), insulation, and reflective paint, as well as to window-to-wall ratios (WWR), with four different glass technologies, can be evaluated. Furthermore, four renewable energy systems were available for comparison: the solar thermal collector (ST), photovoltaic (PV), flat hybrid solar collector (PVT), and low-concentration parabolic solar collector (LCPVT). Our tool was developed based on the results of transient dynamic building simulations of both residential and non-residential building models located in the hot semi-arid conditions of Monterrey, Mexico. Among the results, the small impact of using only reflective paint, the need to combine PCM with insulating material to obtain the best energy savings, and the large impact on emissions savings when using an LCPVT stand out.
