Thermal Comfort Assessment of Underfloor vs. Overhead Air Distribution System

Thermal Comfort in Offices – Natural Ventilation vs. Air Conditioning

Based on both subjective and objective data, a study was carried out in order to identify differences in the perception of thermal comfort of office workers in naturally ventilated and air-conditioned buildings. The analysis of the interviews shows that occupants of naturally ventilated office buildings are significantly more satisfied with their thermal environment than occupants in air-condit...

Alternative Air Conditioning Technologies: Underfloor Air Distribution (UFAD): Technology Focus

Introduction and Background Recent trends in today’s office environment make it increasingly more difficult for conventional centralized HVAC systems to satisfy the environmental preferences of individual office workers using the standardized approach of providing a single uniform thermal and ventilation environment. Since its original introduction in West Germany during the 1950s, the open pla...

Thermal comfort assessment in comfort-prone workplaces.

This paper's main issue is a strong advocacy in favour of an a priori classification of thermal environments that can be really functional to comfort assessment: Class 1, environments where comfort conditions can be established (comfort-prone environments), and Class 2, environments where this is not practically feasible. The former, which are also identified here as 'thermally unconstrained' e...
