On Tuesday 19 December 2017, the Estonian presidency reached a provisional agreement with the European Parliament on a revised directive on the energy performance of buildings. The outcome of the trilogue will be presented to EU ambassadors on December 20, with the final analysis and approval of the agreement expected to take place at the beginning of 2018.

15 December 2017, 10:30-12:00 Brussels time (CET)   We spend 90% of our life indoors in buildings, so the quality of the indoor environment has a major impact on our health, well-being, and productivity. The health, comfort and well-being of building occupants are basic requirements and a human right, therefore both policy makers and the building industry have to take their role in ensuring healthy and comfortable living conditions for people.

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.
