The draft of the European prestandard 17 52, entitled "Ventilation for buildings – Design criteria for the indoor environment" is intended to be a flexible tool for assisting the designer in providing a proper indoor environment for people in ventilated buildings. It specifies how the quality of the indoor environment, comprising the thermal environment, the air quality and the acoustic environment can be expressed.
Controlled ventilation in the workplace offers significant benefits to employee and employer alike, both physical and psychological, says Andrew Saxon.
If a proposed European standard on indoor air quality gets the green light, architects and engineers could face the biggest upheaval in design practice since the invention of air conditioning. Dogged by constant controversy, the so-called Fanger standard is now out for a European vote. The Scandinavians say it will work, the UK says not. Who is right? Building Services Journal and the BRE convened a top team of designers and architects to find out.
Uncontrolled air infiltration in buildings is compromising energy efficiency and wrecking attempts to reduce CO2 emissions. The time is right to act. This month, Building Services Journal announces a joint initiative involving the CIBSE, BRE and the BSRIA, aimed at improving building airtightness. In an exclusive report, ClBSE president Geoffrey Brundrett launches the airtightness campaign.
A knowledge of Russian building thermal-energy codes in effect in the post-World War II era is necessary for estimating the performance of the existing building stock, quantifying the impact of energy conservation retrofits, and estimating the benefits of more stringent codes. This paper begins with a thorough review of the prescriptive-based national codes that applied to heated buildings constructed in the Soviet era. The codes defined all envelope thermal performance requirements for space heating.
