In Tokyo, the urban heat island (UHI) effect induce buildings to greater equipment dependance to regulate their indoor comfort, leading to large amount of anthropogenic heat released and trapped into the urban fabric, disrupting the natural cooling thermostat. In order to deal with the climatic and energetic issues, and to reach our sustainable commitments for 2050, it is of interest to understand the UHI phenomenon on a yearly and daily scale and its relation to the urban form, density and population, before introducing later on passive strategies for medium-rise office buildings, typology that is mostly responsible for microclimatic anomalies in Tokyo.

During their cold winters, they warm small amount of spaces to avoid energy losses and in the warm humid seasons they largely open the envelope and partitions to maximise the air flow. This vernacular architecture is well known by western designers and touists from the world.
With the last century’s conflicts and following rapid economic growth, those principles have been replaced by energy consuming constructions and maintenance systems, reflected by high fossil fuel imports, the pre-2011 nuclear power dependence and the state-of-the-art technology industry. The massive use of air-conditioning and its resulting waste heat is the one of the main cause of the urban heat island effect. This effect have increased Tokyo’s temperature by 3 degrees Celsius since the last hundred years, and is not only responsible for human discomfort and health issues, but also for increasing cooling loads and climatic disruptions.
This naturally leads into the global interest of dealing with the urban heat island effect and building cooling strategies, but unequal considerations are given within the office building sector. Implemented in the small scale building typology, passive strategies such as natural ventilation inspired by the vernacular traditions and tolerant adaptive opportunities could help in greatly reducing microclimatic anomalies, as well as giving a stronger identity to the Japanese built environment.
