PurposeIn many countries, innovation in building design for improving energy performance, reducing CO2 emissions and minimizing life cycle cost has received much attention for sustainable development. This paper investigates the importance of optimization tools for enhancing the design performance in the early stages of Vietnam's cooling-dominated buildings in hot and humid climates using an integrated building design approach.Design/methodology/approachThe methodology of this study exploits the non-dominated sorting genetic algorithm (NSGA-II) optimization algorithm coupled with building simulation to research a trade-off between the optimization of investment cost and energy consumption. Our approach focuses on the whole optimization problem of thermal envelope, glazing and energy systems from preliminary design phases. The methodology is then tested for a case study of a non-residential building located in Hanoi.FindingsThe results show a considerable improvement in design performance by our method compared to current building design. The optimal solutions present the trade-off between energy consumption and capital cost in the form of a Pareto front. This helps architects, engineers and investors make important decisions in the early design stages with a large view of impacts of all factors on energy performance and cost.Originality/valueThis is one of the original research to study integrated building design applying the simulation-based genetic optimization algorithm for cooling-dominated buildings in Vietnam. The case study in this article is for a non-residential building in the north of Vietnam but the methodology can also be applied to residential buildings and other regions.

Design And Construction

The conventional building design and construction have detrimental impact onto the environment. With the current pace of development of the contemporary society, these issues cannot be fully addressed with the concept of sustainable design and construction, which is based on causing less harm to the environment. Thus, the regenerative concept is gaining relevance, as it is changing the construction paradigm toward the delivery of a human-centric environment, which, when coupled with the circular economy, aims to enable the natural environment to evolve. In order to have a more frequent delivery of regenerative buildings, it is necessary to broaden the knowledge on regenerative design, which is the objective of this paper. The aim is to investigate the design process, strategies, and technologies that are applied during the design and construction of a refurbished residential building, which is intended to be the first regenerative building in Spain, and is currently in the process of certification as per the Living Building Challenge (LBC) standard. Therefore, a literature review was performed, followed by a site visit of the case-study building. The research is organized according to the seven categories (petals) of the Living Building Challenge standard, and all 20 imperatives of the LBC are discussed. Additionally, the aspects of costs and project management are investigated. The findings point out the main design features and challenges toward the realization of regenerative refurbishment, in order to fully adhere to the demands of the LBC, and discusses their potential for a broader application in rural as well as urban settings. The analysis of the case-study design and construction can serve as a valuable insight to deliver future regenerative buildings and accelerate their implementation in the construction industry. This article is based upon the work of COST Action RESTORE CA16114, supported by COST (European Cooperation in Science and Technology).

Abstract In this paper, transient analysis on heat transfer across the residential building roof having various materials like wood wool, phase change material and weathering tile is performed by numerical simulation technique. 2-dimensional roof model is created, checked for grid independency and validated with the experimental results. Three different roof structures are included in this study namely roof with (i). Concrete and weathering tile, (ii). Concrete, phase change material and weathering tile and (iii). Concrete, phase change material, wood wool and weathering tile. Roof type 3 restricts 13% of heat entering the room in comparison with roof having only concrete and weathering tile. Also the effect of various roof layers’ thickness in the roof type 3 is investigated and identified that the wood wool plays the major role in arresting the entry of heat in to the room. The average reduction of heat is about 10 % for an increase of a unit thickness of wood wool layer.

Potential Damage

Damaging factors such as airborne microorganisms, relative humidity, ventilation, temperature and air pollutants are the major concerns of the tropical climate of Kolkata, India where our study site, 172-year-old St. Paul’s Cathedral is located. In this context, the aim was to develop an equation to assess the management priority and which factors would be more responsible for potentially damaging the heritage building. The temperature varied from 28°C to 31°C, relative humidity was recorded 72% over a period of 14 days in the prayer hall whereas almost constant temperature (27°C) and relative humidity (55%) were recorded in crypt. Air movement was recorded 0.5–3 m s−1 in both crypt and prayer hall. Sulphur dioxide and oxide of nitrogen concentration were lower than the standard mentioned by the Central Pollution Control Board, India. The fungal load was lower inside the crypt (237 CFU m−3) than in the prayer hall (793 CFU m−3). Calculated potential damage for prayer hall and crypt was found to be 48.75% and 37.08%, respectively. Results revealed that microbial load and relative humidity were the potent factors for damage to the building. Continuous air movement, that is, ventilation and building design here played significant roles. The Heritage Conservation Committee can use the data for better management.

There are six basic control items, land saving, energy saving, water saving, material saving, indoor environment and operation, among which, only material saving are related to structure design. We followed the green building design concept and the control items list in those standards during structure design of one of the residential area in Sino-Singapore Tianjin Eco-city, which consist of 15~18-story residential building connected to a large underground garage, as is shown below.
