This position paper gives a brief overview of opportunities and challenges for ventilative cooling solutions both:
To contribute to the 2020 objectives of the EU in the building sector with regard to energy savings and greenhouse gas emissions;
To contain the overheating risk, which is an increasing concern in low-energy buildings.
venticool partners believe policy makers and standard bodies should take steps together with the implementation of the EPBD recast to accelerate the uptake of this technology.

Many aspects of the Memorial Tunnel Fire Ventilation Test Program (MTFVTP) have made it the most comprehensive of its kind, but none more so than the test facility itself The Memorial Tunnel test facility was truly state of the art in fire ventilation testing. Starting with a two-lane mountain tunnel, the engineering consultants for the MTFVTP designed, managed construction for, and maintained a one-of-a-kind facility that allowed testing of seven ventilation concepts and was capable of withstanding nearly 100 fires-four of which were 100 megawatts (MW) (341 MBtu/h) .
The abstract submission deadline at the 36th AIVC Conference: “Effective ventilation in high performance buildings”, to be held in Madrid, Spain 23-24, 2015 has been extended.
The extended deadline for abstract submission is now April 15, 2015. Authors are kindly invited to submit their abstracts through the online submission system available on the Conference website. Authors will be notified regarding the acceptance of their abstracts by May 29, 2015. Full papers are due by June 30, 2015.
Around 55 participants from 16 countries attended the international workshop on “Ventilation and Airtightness in Buildings : Voluntary and Regulatory Frameworks to Improve Quality and Compliance” which was held in Lund, Sweden on March 16-17, 2015.
One topic of specific attention was schemes implemented in various countries to reduce errors in ventilation and airtightness input data used in energy performance certificates and to improve the quality of the works. Discussions were based on analyses of lessons learnt from field data.

Energy losses from forced air distribution systems have a significant impact on the energy efficiency of buildings. Little work has been done to quantify these losses in apartment buildings. In this paper we will discuss field measurements made on four forced air heating systems to evaluate the duct system energy losses to unconditioned basements. The apartments were heated by natural gas furnaces located in the basements. The systems had bare sheet metal ductwork exposed to the basement conditions.
