Why Solar Shading
Shading against heat gain is one of the most flexible methods of cooling and can be applied to almost all modern buildings.
Solar Shading fitted to a School in Chester
Correctly designed and installed solar shading panels / brise soleil will wholly or partially prevent the ingress of solar radiation which in turn will reduce solar gain.
Great Yarmouth Council Building
The sensation of direct sunlight through a window onto the skin can make occupants feel overheated, as well as direct sunlight reflecting off internal surfaces which can cause glare and eye strain.
Oxford University
Solar Shading systems can be retrofitted onto existing buildings to great advantage, particularly as part of an overall energy reduction scheme or carbon reduction programme.
Correctly designed external solar shading systems both protect against solar radiation and redistribute daylight reducing cooling loads and the reduction of artificial lighting.

Principles of Natural Ventilation
For air to move into and out of a building, a pressure difference between the inside and outside of the building is required. The resistance to flow of air through the building will affect the actual air flow rate. In general, controlled natural ventilation and infiltration are driven by pressure difference across the building envelope. The pressure difference is caused by:
wind (or wind effect);
difference in air density due to temperature difference between indoor and outdoor air (stack or chimney effect); or
combination of both wind and stack effects.
Flow caused by wind
Louvre
Major factors affecting ventilation wind forces include:
average wind speed;
prevailing wind direction;
seasonal and daily variation in wind speed and direction;
local obstructing objects, such as nearby buildings and trees;
position and characteristics of openings through which air flows; and
distribution of surface pressure coefficients for the wind.

Guidelines for natural ventilation
The following guidelines are important for planning and designing natural ventilation systems in buildings:
a natural ventilation system should be effective regardless of wind direction and there must be adequate ventilation even when the wind does not blow from the prevailing direction;
inlet and outlet openings should not be obstructed by nearby objects;
windows should be located in opposing pressure zones since this usually will increase ventilation rate;
a certain vertical distance should be kept between openings for temperature to produce stack effect;
openings at the same level and near the ceiling should be avoided since much of the air flow may bypass the occupied zone;
architectural elements like wingwalls, parapets and overhangs may be used to promote air flow into the building;
topography, landscaping, and surrounding buildings should be used to redirect airflow and give maximum exposure to breezes;
in hot, humid climates, air velocities should be maximised in the occupied zones for bodily cooling;
to admit wind air flow, the long faηade of the building and the door and window openings should be oriented with respect to the prevailing wind direction;
if possible, window openings should be accessible to and operable by occupants;
vertical shafts and open staircases may be used to increase and generate stack effect;
openings in the vicinity of the neutral pressure level may be reduced since they are less effective for thermally induced ventilation;
if inlet and outlet openings are of nearly equal areas, a balanced and greater ventilation can be obtained.
