Special Issue Information

Dear Colleagues,

It is our pleasure to announce a new Special Issue “Healthy and Sustainable Built Environment Solutions towards Building Decarbonization” for the journal Sustainability.

The building sector accounts for the largest proportion of human-activity carbon emission in most countries all over the world. In order to create and maintain a healthy and sustainable built environment, both active and passive technologies are typically employed. The decarbonization campaign in response to severe climate change happening to our planet has shaped the technological means to create sustainable and resilient built environments. In urban planning and building science, solutions to improve the efficiency of active technologies, such as high-performance ventilation means, innovative heating/cooling systems, as well as the absorption/adsorption/infiltration means to improve indoor air quality are emerging rapidly. These are not only basic demands for the comfort and health of occupants, but also necessary in some industrial areas, such as pharmaceutical and chip production, not to mention human well-being during and post the COVID-19 pandemic era. In most climatic conditions, sustainable active solutions should be utilized to create better built environments in place of intensive carbon emission. As the collateral objectives of sustainability, built environments and decarbonization are both important. Practical and innovative progress in various engineering disciplines and cross-disciplines should be discussed to facilitate the imperative simultaneous solutions of built environments and decarbonization.

This Special Issue aims to discuss solutions towards a healthy and sustainable built environment within the context of building decarbonization. It is open to all sustainable science and engineering disciplines and research addressing the issues and progress for current and future built environments.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Ventilation systems and technology to create better indoor and outdoor environments and save energy for cooling (ventilative cooling);
  • High-energy-efficiency building science and technology towards decarbonization;
  • Innovations in the building envelope in extreme hot/cold climates to reduce building carbon emission;
  • Intelligent control and monitoring of built environments;
  • Healthy building environments;
  • Building integrated photovoltaic and indoor thermal environments;
  • City and building aerodynamics and indoor air quality.

Botanical garden greenhouses typically use solar radiation as an important heat source and meanwhile provide light for plants to survive. However, in the summertime, when the solar radiation is too strong, overheating will occur in the greenhouse and natural ventilation assisted with shading is used to cool it down. The modulation strategy of shading is very important not only to indoor temperature but also to the growth of plants. In order to determine the control strategy of the shading area in the design and installation stage, a CFD model of an exhibition greenhouse in Shanghai is established. During summer conditions, under the worst-case scenario of a windless day, the minimum shading area needed under different outdoor comprehensive temperatures is studied, and the correlation curve is fitted to guide the control of the shading to maintain appropriate thermal conditions. The decrease in indoor temperature under different shading areas is also explored when the outdoor comprehensive temperature is 34 °C. The annual carbon emission reduction of the greenhouse is about 500 t CO2, by adopting shading and natural ventilation. This study provides a reference value for shading control and energy saving and emission reduction of a botanical garden greenhouse. Full article

The literature showed many studies that evaluated single or multiple Phase change materials (PCMs) layers in passive, active, or in hybrid configurations for building applications. However, little attention has been given to evaluating the energy performance of buildings when PCMs are used together with other passive design strategies. In this work, the energy performance of an office building in a typical arid Saharan climate is simulated using EnergyPlus when a PCMs-embedded envelope is implemented. The office building was analyzed without/with PCMs using various thicknesses. Results indicated that the annual electrical energy for heating, ventilation and air conditioning (HVAC) could be reduced between 3.54% and 6.18%, depending on the PCM thickness. The performance of the office building, including PCMs, was then simulated using two practical architectural design strategies, namely windows-to-wall ratio (WWR) and rezoning of the interior spaces. Outcomes revealed that the annual energy consumption for HVAC can be reduced from 10% to 15.5% and from 6.1% and 8.54% when WWR is reduced by half to three-quarters, and the perimeter zones are enlarged by one-third to two-thirds of the original space area, respectively. By combining both architectural design strategies and PCM, the annual electrical HVAC energy can be reduced between 12.08% and 15.69%, depending on the design configuration and PCM thickness. This design option provides additional benefits also since it reduces the vulnerability of increasing the lighting and fuel gas heating energy because more perimeter zones are exposed to daylighting and solar radiation, respectively.
