(TheUrbanDeveloper.com‚ 2015). Concrete structures are known to exposed to harsh elements and in result it will eventually weakens the structure. Therefore‚ researchers from Delft Technical University in Netherlands created a formula of self healing material. They’ve called it the Bioconcrete. It is made up of two components; bacillus spores and calcium lactate nutrients. They are made in to pellets that are added in to the wet concrete mix. Years later when cracks begin to form and appear‚ water will

Radiant barriers are installed in buildings to reduce summer heat gain and winter heat loss. In new buildings‚ you can select foil-faced wood products for your roof sheathing (installed with the foil facing down into the attic) or other locations to provide the radiant barrier as an integral part of the structure. For existing buildings‚ the radiant barrier is typically fastened across the bottom of joists‚ as shown in this drawing. All radiant barriers must have a low emittance (0.1 or less) and

Loft insulation Loft insulation is needed to save heat energy and contain it within the building. It reduces heat because hot air is lighter than cool air therefore hot air rises. Therefore the hot air that rises will stay at the top. Meanwhile the air below begins to gain heat and in turn rises while the hot air above loses heat and falls. This cycle is called convection. Loft insulation acts like a blanket‚ helping prevent heat escaping through the roof. Insulating your home isn’t a one
