WindowMaster helps raise standards in education

WindowMaster, natural ventilation
Natural ventilation supplied and installed by WindowMaster will play a key role in the environmental strategy for this new school in Lambeth.

The first school in the Government’s Building Schools for the Future programme to receive an ‘Excellent’ rating from the Committee for Architecture and the Built Environment includes a natural-ventilation system supplied and installed by WindowMaster. The first phase of the new Stockwell Park High School is designed by architects Sheppard Robson and is being built by Wilmott Dixon. The £19 million project is due for completion in November 2010.

On the ground floor, natural ventilation is provided by opening windows and louvres, all controlled by NV Advance. There are opening windows on the first floor. This combination of products gave the school the security it needed.

The WindowMaster system controls 110 Velfac motorised windows, 128 louvres on the ground floor, Duplus windows and 30 roof windows. The 84 zones in the classrooms are controlled by carbon-dioxide sensors, with temperature sensors in other areas.

The control system understands and knows how wind speed and direction on all facades will influence airflow through the windows on each level and location in the facade. WindowMaster determines the pressure coefficient (Cp) for each window by calculating the relevant air pressures form different wind speeds and directions.

Computational fluid dynamic calculations are carried out for 16 wind directions for the specific building and its surroundings. Cp values are determined and programmed into the control system so that each window can be precisely controlled.
