The YKK 80 building located in central Tokyo aims to realise better energy saving and thermal comfort compared to a conventional radiant cooling system by utilising a slight airflow to improve comfort criteria and relaxation. This paper presents the actual performance of an advanced radiant cooling system based on a mock-up experimental study and on-site investigations into the occupied building. As a result of investigations, the actual performance of the system is verified.

The YKK 80 building was awarded first place in the ASHRAE Technology Award 2017 and was certificated as LEED CS Platinum in 2016.

The ideology of Passivhaus is clear. It is a building standard associated with a really well insulated and airtight building that saves energy – in both hot and cold climates. There is evidence from that shows how important this approach to building is in achieving carbon reduction targets. Passivhaus is a credible way for large scale energy reduction in the built environment and has gained in popularity with policy makers tasked with meeting the internationally agreed climate change targets. The reality of living in a Passivhaus is not so clear. There is evidence of some Passivhaus projects using much more energy than the design models anticipate. There is also emerging evidence of the difficulties some people face in living in a Passivhaus. Issues of air quality, systems control problems, inadequate technical knowledge and skills. While the overall picture is positive there are clearly issues to be overcome in the delivery of a promising carbon reduction strategy for the built environment. This research explores the limitation of the PHPP software in addressing the lived experience of Passivhaus. The emerging issues with some PH projects suggest a better understanding of the interactions between people and the building is required.

Despite the recent pursuit towards Zero Energy Buildings (ZEB), their global adaptation is far from complete, mostly in cooling dominated climates which are still poorly prepared for their integration. This paper reports on a research project aiming to build a road map for the local adaptation of the ZEB concept in Israel. The methodology of this research was based on a statistical top-down feasibility analysis which explored the possibility of 10 different urban typologies to achieve zero energy balance using the Load Match Index as the performance metric. Results demonstrated large potential variations between residential and office uses as well as between different typologies to deliver zero energy balance in the Israeli context. Findings helped generate detailed criteria and four different models for Zero Energy Buildings in Israel towards new policy.

With the upgrading of education mode and the architecture discipline development in the informatization context, modern architecture education has gradually shifted from top-down elitism education to bottom-up humanism education, the contradiction between the traditional enclosed space and the growing demand of the Architecture Department Building's environment is the key to the development of architecture education. For cities in cold region, the quality of the architecture education space is threatened by severe cold climate. In the informatization context, optimizing spatial environments is facing severe challenges. Based on the theory of interaction demand and bioclimatology, this paper takes the School of Architecture of Harbin Institute of Technology (HIT) as an example, proposes regeneration strategies and conducts CFD simulation to verify the effectiveness of the design which provides reference to the traditional Architecture Department Building's redevelopment in the cold region.
