Energy performance tests for Shogakukan Building

Summary

Project description

The Shogakukan Building project raises the goal of establishing a more comfortable and energy-efficient space and system that befits a workplace for the creative undertakings of a publishing company. One approach taken to achieve this goal is the combination of thermo active building systems (TABS) using corrugated slabs and a convection air-conditioning system. In order for the air conditioning system to demonstrate its expected performance in the operation phase, we conducted performance tests using BEMS data and system simulations, and proposed improvements based on the results.

Technical features

Operational issues were clarified through quantitative analysis of the operations of the air conditioning system based on BEMS data. System simulations using LCEM were also carried out to provide advice on matters such as adjustments to the TABS supply water temperature and length of supply time, and the duration of operations of the external air conditioner. Proper operations based on this advice contributed to the reduction in annual primary energy consumption by 16 percent from the first year of operations.
