Modern timber frame, kit houses, modular construction, prefab, buildings have a number of advantages but are they particularly green?
Not necessarily. The thing is you generally have more control so they lend themselves to energy efficiency.
The question of embodied transport related energy needs to be asked. This needs to include transport of material from its source to the OSC manufacturer and from there to the site.
For the sake of clarity here are the advantages of off site construction which tend to make them energy efficient if they are managed properly:
• Better quality
• Increased productivity
• Controlled weather tight environment
• Pollution and waste controlled and minimised
• Water recycled
• Greater airtightness
• Less noise, traffic, pollution on site
• Lightweight = smaller foundations / less ground work / less concrete / less moving solid
