Energy Efficiency Improvement Project

Thursday, April 23, 2015

Purpose of the project:

The following case study is an example of the energy efficiency improvements carried out in Wihlborgs’ existing portfolio in 2013. At the end of 2012 we acquired the St.Jorgen 20 (Baltzar City in Malmo) property. Baltzar City is an office building with shops on the ground floor. It covers an area of 11,350 m2. Via a combination of our experienced operating personnel and Wihlborgs’ energy statistics software, we established that better use could be made of the existing technology. The potential lays in the existing control and regulation system.

Approach:

The following measures were implemented:

  • Reprogramming of functions to optimize the entire cooling system
  • Adjustment, set correct temperature for transmitters and correct humidity for sensors
  • Adjustment of pumps connected to the heating system

Results:
