Overview
This guide provides an examination of the issues relating to oversized heating, ventilation and air conditioning plant. It also presents a methodology for identifying where plant is oversized and for assessing the extent of this. It gives recommendations for remedial measures, and supplies plant monitoring tips and case studies. The guide also states the guidance will help reduce energy expenditure and will be an invaluable source of information for those considering plant refurbishment. By highlighting the origins of overdesign, aims to make designers more aware of their responsibility when it comes to sizing HVAC plant and systems. The main steps to reduce the energy consumption of oversized plant described are - targeting plant oversizing, assessing and optimising operation and maintenance practice, accurately quantifying plant overcapacity by plant monitoring and implementing remedial measures to improve system performance.
