by François Durier (CETIAT)   Advanced controls for heating, ventilation and air conditioning (HVAC) systems can reduce consumption in unoccupied zones of a building. They can also continuously adapt the operation to fit the demand and detect needs for maintenance. They are based on sensors and use control strategies adapted to the technology of the system, by modulating temperatures, flow rates, capacity, etc.

IEA Technology Collaboration Programme on Heat Pumping Technologies - Annex 36 - Quality installation / quality maintenance sensitivity studies - Executive Summary  
Post date: 12 Dec 2017
Type: Publication

Numerous studies and surveys indicate that typically-installed HVAC equipment operate inefficiently and waste considerable energy due to varied installation errors (faults) such as improper refrigerant charge, incorrect airflow, oversized equipment, and leaky ducts. This article summarises the results of a large United States (U.S.) experimental/analytical study of the impact that different faults have on the performance of an air-source, single-speed heat pump (ASHP) in a typical U.S. single-family house.

The Energy Efficiency Indicators database contains annual data from 2000 to 2015, covering end use energy consumption for 8 energy products, end use energy efficiency indicators, and carbon intensity indicators for 4 sectors (residential, services, industry and transport) for the IEA member countries. The indicators are computed by using key sectorial activity data, for example, passenger kilometre energy intensity by mode/vehicle type (MJ/pkm).

This statistical report by the International Energy Agency (IEA), is designed to help understand what drives final energy use in IEA member countries in order to improve and track national energy efficiency policies. It is the second edition of a comprehensive selection of data that the IEA has been collecting each year, after its member states recognised in 2009 the need to better monitor energy efficiency policies. The report includes country-specific analysis of end uses across the largest sectors – residential, services, industry and transport. It answers questions such as:

  The Indian Society of Heating, Refrigerating and Air Conditioning Engineers (ISHRAE), was founded in 1981 at New Delhi by a group of eminent HVAC&R professionals. Today, ISHRAE has more than 12,000 HVAC&R professionals as members and additionally there are 7,500 Student-members.   ISHRAE operates from 41 Chapters and sub Chapters spread all over India, with headquarters in Delhi. It is led by a team of elected officers, who are members of the Society, working on a voluntary basis, and collectively called the Board of Governors.
