“…For the energy efficiency of buildings in cold regions, the body shape coefficient and the window-wall area ratio are two very important controlling indexes, but the energysaving renovation of existing buildings cannot be optimized and strengthened from the two aspects of the body shape and the window-wall area ratio. It can only be renovated based on the aspect of changing the thermal insulation measures of the enclosure structure [28]. Therefore, enclosure structures such as walls, roofs, doors, and windows were the focus of this study on energy-saving renovation.…”

Concerning the double carbon national strategy, the energy-saving renovation of old buildings has become one of the most important tasks of energy conservation and emission reduction in construction in China. There are many problems, such as high energy consumption, thermal environment, and poor thermal comfort. Taking Lhasa as an example, this study adopts field research, questionnaire interviews, on-site measurements, numerical simulations, and other methods to propose suitable energy-saving potential excavation points and thermal optimization strategies for office building envelopes in Lhasa through software simulation. Additionally, typical office buildings are selected to carry out the energy-saving renovation of envelopes with the goal of improving indoor thermal comfort to validate the feasibility of the energy-saving renovation strategies. The results show the following: (1) The measured and predicted thermal neutral temperatures of the office population in Lhasa are 16.5 °C and 18.9 °C, respectively. The 90% acceptable temperature range is from 16.10 °C to 21.77 °C, and the occupants of the office buildings in Lhasa have a higher tolerance for cold than predicted. (2) The passive measures adapted to Lhasa are prioritized in the order of passive solar energy, high-heat-capacity materials, and nighttime ventilation. (3) Through the optimization of the enclosure structure of existing office buildings, the improvement of the heat storage capacity of the outer enclosure structure, and the increase in the window opening area to increase natural ventilation, the indoor thermal comfort of the renovated buildings is effectively improved.

“…The design phase concerning the implementation of environmental, social and economic aspects, related to the building process requires grouping and coordination of several specialists from different disciplines (He et al , 2009; Hansen and Augenbroe, 2002). This phase is characterized by continuous verification activities of design choices, at different scales, throughout the design and building process.…”

PurposeThe achievement of sustainable architectures, including control of energy relations between climate and built environment, in order to optimize energy consumption and reduce environmental impact, requires an integrated planning dealing with a multi‐scale and integral view of building‐plant system. The purpose of this paper is to describe the design of a multifunctional complex, namely “Solaria”.Design/methodology/approachThe proposed integrated approach focuses on comfort and healthy living, sustainability of building process, containment of energy consumption and use of renewable energy sources. The building object of this research has been designed including: a high‐efficiency tri‐generation plant (525kW of electric power) coupled with a distribution network for district heating/cooling; a photovoltaic generation system with 20kW of peak power and solar thermal panels for sanitary hot water production (able to supply over 50 per cent of needs); and passive solar systems (solar greenhouses and “heat cushions”) equipped with sliding brise‐soleils.FindingsThe proposed integrated design approach has enabled the achievement of important results, such as the avoidance of CO2 emissions, equal to nearly 500 tons per year. Moreover, energetic and environmental‐achievements have been certified by using various methodologies. Finally, environmental and costs analyses have been carried out in order to compare the proposed approach with traditional ones.Originality/valueThe case study proposed in this research represents a repeatable and practical application of European Directives on the energy performance of buildings (2002/91/EC) and energy end‐use efficiency and energy services (2006/32/EC). As a consequence, this research adds to the current body of knowledge.
