The advantages and possible further use of the developed monitoring tool were also discussed in the Task Force Workshop “Ventilation and AC inspections in Cold Climate countries” organised during the Annual Meeting. The presentation of experts from Nordic countries showed that there is a clear need for further practical guidance for member states – including the ones considered as more advances in this field, which have already implemented the EBPD regulation on the monitoring of AC systems. In the following REHVA Technical and Research Committee it was agreed that the AC Inspection Task Force will include instructions and guidance about the monitoring of AC system based on iSERV in its upcoming AC inspection Guidebook.

Power Demands of Heating, Ventilating and Air Conditioning components in EU Buildings

The importance of understanding energy use at HVAC component level

A previous paper in the January 2104 REHVA Journal (Knight, 2014) proposed that detailed monitoring of energy use at HVAC component level was likely to be a key element in achieving sustained reductions in energy use in EU buildings. To use this detailed monitoring to its full potential it needs to have benchmarks against which it can be compared, and Power Demand benchmarks are a key component for identifying Energy Conservation Opportunities.

The iSERVcmb project (www.iservcmb.info) is producing what is believed to be the first public dataset of measured energy and power consumption of HVAC components operating in European Buildings. This paper presents a brief overview of a subset of this data, normalised Power Demands, to illustrate some of the forthcoming outputs from the project this summer.

The Power Demands presented here are from measured data obtained during the iSERVcmb project. It was taken from 1700+ HVAC systems and components drawn from across Europe, which are servicing a variety of activities and floor areas. This measured data is a key element in the HVAC system benchmarking process proposed and tested by iSERVcmb across 16 EU Member States.

With such a large dataset it is inevitable that the data covers a wide range of years, and as such will continue to be analysed at finer levels of detail before the end of iSERVcmb to explore different ways of examining the data. However, the full dataset present at the time of this paper is used to provide the largest data source possible for analysis here.

Due to the analysis work still to be completed, this paper therefore provides only an overview of the ranges of Power Demands being found in practice by HVAC Component Type normalised by Area serviced by that component. Note that this floor area is derived from the iSERV spreadsheet and is therefore much more accurate than simply relating power demand to total building floor area.

Measured Energy Use by HVAC components

The iSERVcmb process philosophy is based around physically quantifiable parameters i.e. energy, space, activity types, and HVAC system components. A HVAC component could be, for example, a fan, pump, air handling unit, cold generator, etc. There are subcomponents of these component types…..To read the full article, download the attachment below.

REHVA is pleased to invite you to its 2014 Seminar on Energy effective operation of HVAC systems jointly organised with the iSERV project consortium.

The seminar will cover a wide range of topics: updates from high level EC speakers on EU policies related to buildings energy efficiency including the new financing opportunities; how to increase the energy efficiency of HVAC systems through monitoring; results of the iSERVcmb project and a discussion about their deployment from a policy and an industrial perspective.

Come and share your experience and expectations. We will be delighted to welcome you at our event, which is a perfect networking opportunity with practitioners, companies and researchers working on buildings energy efficiency.

Our seminar is of particular interest of HVAC system manufactures, REHVA supporters, policy makers, academics in the field of HVAC, as well as consultants, practitioners and engineers in building services.
