The annual maintenance of gas boilers in France

This document, produced by Cegibat, the information center of the French gas distribution company GRDF (Gaz réseau distribution France), provides a detailed list of the operations that need to be performed during the annual maintenance of a domestic gas boiler, from 4 to 400 kW. It presents the operations required by the French regulation (heating systems inspection) and gives further recommendations. It covers checks, cleaning and adjusting of the appliance.

Boiler room commissioning

Commissioning of a boiler room is the process of assuring that all systems and components are designed, installed, tested, operated and maintained so that the awaited performance is reached. This document by Cegibat, the information center of the French gas distribution company GRDF (Gaz réseau distribution France), describes in 7 steps the commissioning of a boiler room, from the project design to the operation. A check list is also available showing in detail the unitary operations of the commissioning of a boiler room that can be used to ensure its traceability.  


The green light for green buildings: retrofitting Europe

Retrofitting public buildings is crucial to meeting Europe’s energy efficiency goals. But can new knowledge in retrofitting be replicated across the EU


The move to energy efficient buildings is on. Two European directives are gently nudging things along, by requiring that 3% of public buildings be renovated every year and that public buildings be almost energy zero by 2018.

Four University Teams Top Winners in ASHRAE Student Design Competitions

British Columbia, California, Florida and Regina Teams Top Winners in ASHRAE Student Design Competitions



ATLANTA, 31 August 2016 – Students from eight countries put their engineering skills to the test to design and select systems for a government building in China, as well as for a competition requiring them to “think globally, act locally.” Both competitions are held by ASHRAE.


AIVC September 2016 Newsletter

Following the approval by the Executive Committee of the International Energy Agency (IEA) Energy in Buildings and Communities (EBC) Programme regarding the continuation of Annex 5 - Air Infiltration and Ventilation Centre (AIVC) for the period 2017-2021, this tenth issue of the AIVC newsletter aims to provide information on the centre’s R&D related activities as well as its high impact dissemination activities involving the organisation of events, the production of publications, the cooperation with well-established organisations etc.

Strengthening energy security in South-East Europe by investing in buildings

An analysis of the vulnerability to gas supply disruptions concludes that Central and South East European (SEE) countries are facing a strategic choice. The latest BPIE report finds that Slovakia and Hungary face a severe risk, and Bulgaria a substantial risk to be unable to heat the national building stocks. The report presents a new Building Vulnerability Indicator and offers an alternative solution to mitigating supply risks through building renovation.

Going sustainable to rejuvenate the suburbs

Peripheral areas often face poverty, crime, waste, pollution and decay. A new trend, however, considers suburbs the best places to develop green initiatives and energy efficiency interventions. Now a social housing building in Zaragoza, Spain, is piloting the regeneration of a suburb


Peripheral neighbourhoods are often spaces of poverty, unemployment and urban decay. But now many peripheral areas are becoming laboratories of innovation, hosting initiatives for a sustainable future.


OVERVIEW – Ecodesign and Energy Labelling of gas and oil boilers

Two European Directives – the Ecodesign and Energy Labelling Directives – and their accompanying regulations have introduced new requirements for fossil fuel boilers, as well as a label to inform about their performances. This article presents these requirements and the foreseen label.
