Correlation between standards and the lifetime commissioning

Abstract

This paper reviews the applicability and drawbacks of available European and international standards related to lifetime commissioning, by structuring them into Norwegian commissioning procedures. The work describes research on lifetime commissioning that proposes a generic framework on building performances. The generic framework describes a component in HVAC system by performances. The results of the standard review show that there is a need for measurement and testing standards in hydronic systems. In addition, there is no generic framework on the definition of energyefficiency measure in the reviewed standards. Findings on a case study, where lifetime commissioning procedures were tested, are presented. After the performances of the case study were defined by the generic framework, it was found that 20% of all the performances can be monitored by a building energy management system. Due to good operation, the building managed to achieve 3% lower energy consumption than design a year after the building was taken in use. In addition, results show that energy signature curves can be used only in a modified way to predict heating consumption, while electricity consumption can not be described in that way.

Lifetime commissioning as a tool to achieve energy-efficient solutions

“…The method has been reported in [8]. The aim of the procedures is to create a good information system between all the participants during the building lifetime.…”

“…This framework describes building performance as a data model [8]. In our study, a generic framework on building performance is suggested.…”

“…Since the documentation of ventilation system is better than the documentation of other building systems [8], it was possible to find detailed data on each VAV damper and corresponding air diffuser. After these data were collected, it was possible to perform diverse inspections on available data.…”

“…Since a building process is typically split into fragments with different participants, information loss appears with performance degradation as a consequence [8]. Further, this information loss induces performance degradation as well.…”

Energy saving in the street lighting control system—a new approach based on the EN-15232 standard

“…This standard concerns the impact of the BACS and the TBM on energy performance and energy use in buildings. There are four BACS efficiency classes described in this document: (i) the class A corresponds to the BACS with very high impact on energy consumption, (ii) the class B-the BACS with high impact on energy use, (iii) the class C-the BACS with low impact on energy consumption and (iv) class D-the BACS without any impact on the energy consumption in buildings (Djuric and Novakovic 2010;Schönenberger 2015). Considering this, and taking into account the assumptions for the classes as well as the functions available in the street lighting control system, in our experiment, we propose four different functional strategies (EN 15232 Standard 2012):…”
