  • The energy crisis of the mid 1970’s gave birth to a movement to conserve energy. Over the ensuing years much has been done to reduce the energy consumption of new and existing buildings. Lighting efficiency has improved so much that today we use ½ the wattage without sacrificing lumens. Improved construction methods, better insulation and high efficiency windows have also helped reduce energy consumption. However, all of these measures have resulted in a reduction of Sensible heat gains while Latent heat gains have increased.

  • The late afternoon sun hid behind gray banks of snow clouds and a cold wind whipped loose leaves across the drill field in front of the Philadelphia Barracks of the North American Continental Thruway Patrol. There was the feel of snow in the air but the thermometer hovered just at the freezing mark and the clouds could turn either into icy rain or snow.

  • Inasmuch as adenoids are tucked away up behind the palate, and are therefore out of sight, it may be well to study the picture shown above. The air passes into the lungs as shown by the arrows. At the place marked "A T" nature has provided a kind of moist cushion which helps to filter impurities out of the air. This cushion is formed of what doctors call "adenoid tissue" and is similar to that which makes up the tonsils. When this adenoid tissue grows abnormally large it forms what are known as "adenoids." From the position of these adenoids as shown on the diagram...

  • Many Roman villas had under-floor heating which would have been especially useful in the British winter! The Roman name, hypocaust, is Ancient Greek meaning ‘fire beneath’. The floor was supported on short columns made of stacked tiles. A fire would be kept burning (very hard work for the slaves!) in the furnace room, and the hot air would move through the under-floor area, heating the rooms above. The hot air and smoke escaped through channels in the walls. To make your hypocaust system, you will need to raise up your whole villa by around 6cm.
