Fundamentals of Building Energy Management and Conservations-Green Building-Part II

Building as an Energy System, Energy Saving Approaches for Building, Passive Design: Passive designs take advantage of local climates and reduce energy consumption for heating or cooling the building by optimizing insulation, ventilation, orientation, and shade of a building.

Outline:

1. Building as an Energy System
2. Energy Saving Approaches for Building
3. Passive Design
   • Form and Orientation
   • Minimizing heat gain through roofs: Cool roofs, Green roofs, External shading
   • Fenestration, the properties relevant to daylight harvesting and energy efficiency: Solar Heat Gain Coefficient (SHGC), Visual Light Transmission (VLT), U value, Light to Solar Gain Ratio (LSG)
   • Effective building material sealing, High performance glass, Windows with low solar heat gain coefficient (SHGC), Low-E Glass, Double-glazed units, Triple-glazed units, Thermochromic and Electrochromic Glass, Double skin facades
   • Low energy cooling: Natural ventilation, Stack-Effect ventilation, Passive downdraft evaporative cooling (PDEC)
   • Thermal insulation
   • Lighting: Daylighting, Light Shelves
