Low energy strategies in urban areas.

            

The big friendly giant.

The new headquarters of the Commerzbank in Frankfurt - the tallest office building in Europe - has proved one thing conclusively: it is possible to build a vast high rise in the middle of a busy city and use passive techniques to control its internal environment

NatVent European project: guidance on technical solutions for low energy ventilation in office buildings.

NatVent™ is a seven nation pan-European project which aims to reduce primary energy consumption (and consequently C02 emissions) in buildings by providing solutions to barriers which prevent the uptake of natural ventilation and low-energy cooling in countries with moderate and cold climates. It also aims to encourage and accelerate the use of natural ventilation and 'smart' controls as the main design option in new-designs and major refurbishments of office-type buildings.

Air flow distribution in a naturally ventilated light weight room.

The objective of this research is to investigate air flow distribution inside a light weight test room which is single sided naturally ventilated. The ventilation rate into the room is controlled by adjusting four sets of louvres. The local outside air temperature, humidity, pressure, wind velocity and direction were measured. Inside the room the velocity and direction of the inflow air across the high and low level openings, temperature and velocity distribution at four locations and six levels across the room were recorded.

Thermal comfort simulations for different structured naturally ventilated room.

The objective of this research was to investigate thermal comfort with respect to the mass of the building inside a test room which is naturally ventilated. The room is an existing portable cabin of light mass, located at Loughborough University. The comfort parameters for different mass of the cabin were predicted. For this purpose a simulation package, is used to calculate the thermal parameters defined by Fanger. Medium and high thermal masses were added to the test room and their effects on thermal comfort were investigated.

A novel thermal simulation model and its application on naturally ventilated desert buildings.

A new thermal simulation model, QUICK II, is presented and numerous verification case studies performed on naturally ventilated buildings are discussed. Four new case studies performed on two buildings located in the Negev desert in Israel are discussed in detail. All the measurements pertaining to these new case studies were taken independently by the Desert Architecture Unit of the Jacob Blaustein Institute for Desert Research. These measurements are provided, along with a description of the buildings.
