Naturally Tokyo: found in translation?: A case study of Dutch Earth, Wind, and Fire system integration & optimization in an office building in Tokyo

Earth, Wind, and Fire (EWF) is a natural ventilation system developed by Dr Ben Bronsema for office buildings in the Western European climate. Powered by nature: ground temperature & gravity for cooling, wind for energy generation & ventilation, and sun for the heat and natural draft, this system claims not only to use little energy but...

Refurbishment of an office building in the Netherlands using the Earth, Wind and Fire system

The built environment is the largest energy consumer in the European Union in which the non-domestic sector accounts for 13% of the total energy consumption and the office buildings account for 50% of the energy consumption. The office buildings in the Netherlands exhibit poor energy performance and thermal comfort. There is an urgent need to...

Thermal and Electric Performance of PV/T Solar Chimney System

The residential and service sectors are responsible for the 39% of the total energy consumption. 80% of this energy is used for heating purposes. Achieving nearly zero energy buildings is a major goal for the near future. The design of an integrated electrical and thermal system can substantially help to reach such objective. The façade is the...

Photovoltaic chimney: Thermal modeling and concept demonstration for integration in buildings

This work presents the concept of a photovoltaic (PV)-powered solar chimney. We modeled and experimentally studied the integration of a PV system within a naturally ventilated façade (NVF), attempting to use the inherent cavity as a ventilation channel to transfer heat. Thermodynamic models were created to study the thermal and, therefore,...

Façade for wind and stack driven ventilation in tropical high-rise office

Cooling load reduction for high-rises is a necessity for further developement for the densification of urban areas. This study describest the approach for HVAC cooling reduction potential for tall-office buildings in Singapore. Via passive ventilation strategies and adaptive thermal comfort the comfort temperature is increased what leads to a...

Earth, Wind & Fire: Natuurlijke Airconditioning

Collaboration between the Universities of Technology in Delft and Eindhoven has resulted in the development of a new concept for natural air conditioning of buildings. According to the so-called Climate Responsive Architecture developed in this research, the design of the indoor climate system, building physics, and services are linked to an...

A naturally ventilated office building through solar chimneys and 'venturi' exhausts

At the Faculty of Architecture, Urbanism & Building sciences of the Technical University in Delft, research is being executed on the specific characteristics and performance of the driving ventilation components: solar chimneys and wind-induced exhausts. Along with this development the performance of a natural ventilated office building model...
