07 Environmental Consideration (ZEB) [Design and Construction Supervision] [Consulting]

ZEB proposal and application process

With the government's goal of achieving ZEB standards for the average stock by 2050 and the increasing asset value of environmentally friendly buildings, an increasing number of companies are aiming to obtain ZEB certification for existing buildings. Based on the extensive know-how we have cultivated through our track record of energy conservation through many Renovation, we will realize ZEB and handle the various applications that accompany it.

ZEB is an abbreviation for Net Zero Energy Building, and refers to a building that aims to reduce the energy consumption of the building to zero through 1) energy conservation and 2) the use of energy creation, while providing a comfortable indoor environment.

STEP 1: Understanding the current situation and extracting ZEB candidates

We grasp the current situation based on existing building data and existing drawings, identify the possibility of ZEB conversion, and select candidate properties if the company owns multiple buildings.

STEP 2: Consider ZEB renovation methods

Using our unique simplified energy-saving calculations, we will consider ZEB renovation methods from a design perspective.

STEP 3 Energy saving calculation and application

We will carry out a performance evaluation using energy-saving calculations, and based on the determined ZEB renovation method, we will create drawings and apply for ZEB certification in accordance with the Building Energy Efficiency Labeling Scheme (BELS).
