Analysis on building envelope and building service equipment design specification using the input and output data from the calculation program to confirm compliance with building energy code (part 1): Identification of the design specification for newly built offices in Japan according to the evaluation result of the building energy code

It is essential to clarify the actual design specifications of buildings in order to plan future energy conservation measures. This paper focuses on the single purpose office buildings built in the financial year of 2018 and analyses the data on building envelope and equipment specifications from the calculation program to confirm compliance with building energy code. This paper shows that the office buildings can be classified into 5 groups according to the evaluation index of the building energy code and identifies the standard design specifications of building envelope, air-conditioning system, lighting system, and solar power generation for each group. © 2020 Architectural Institute of Japan.
