sustainable energy conservations strategies that could be used in the bank branch
Sustainable energy conservations strategies that could be used in the bank branch:
  • Smart ventilation – to reduce HVAC (transitional seasons)
  • Overhangs – to reduce cooling load (cooling season)
  • Daylighting – to reduce electricity use (all year)
  • High performance windows – to reduce HVAC (all year)
  • Passive heating – to reduce heat load (heating season)
sustainable energy conservations strategies that could be used in the bank branch2
Sustainable energy conservations strategies that could be used in the bank branch:
  • Photovoltaic energy production and solar hot water (all year – made attractive by new tax incentives)
  • High reflectivity, high emissivity roof – to reduce cooling load (cooling season).
doe energy star building designation
DOE Energy-Star Building Designation
  • Leed’s certification is too expensive.
  • US Dept. of Energy now has a designation for buildings that meet energy conservation criteria.
    • Less burdensome than Leed’s
  • See: http://www.energystar.gov/index.cfm?c=small_business.sb_index
new jan 2006 tax incentives for energy conserving technologies
New (Jan 2006) tax incentives for energy conserving technologies:
  • $1.80/sq ft for commercial buildings that are constructed to save at least 50% of the heating, cooling, water heating, and interior lighting energy cost of a building that meets ASHRAE Standard 90.1-2001.
  • Solar Energy Systems - The tax credits are for 30% of the cost of the system (PV & hot water).

  • Maximize reflection and radiation heat loss.
  • Reduce cooling load, energy use, and equipment sizing
  • Longer life span
  • Options: PVC – TPO – EPDM – Spray
technologies daylighting
Technologies: Daylighting
  • Features:
  • Many options available
  • Drive light deep into the room
  • Unobtrusive
  • Inexpensive

six keys to daylight design
Six Keys to Daylight design:
  • Prevent direct sunlight penetration
  • Provide gentle uniform light
  • Avoid glare
  • Control
  • Electric lights work with the daylight
  • Plan the layout of interior spaces
skylights and solar tubes
Skylights and Solar Tubes
  • Specific applications
  • Gets light far into a building
  • Saves lighting energy
design options
Design options:
  • Roof Monitors
  • Clerestories
  • Lightshelves
  • Controls
  • Lightwell
  • Surface color
  • Visible Light Transmission
slide11

Keeping light diffuse, minimizing direct heat gain,

and maximizing penetration are critical.

building cost of daylighting
Building cost of daylighting:
  • One example: Daylighting cost = $1.23/ft² (about half of building is daylit).
    • Includes roof monitors, light shelves, lighting controls, cloth baffles, etc.
  • Reductions in peak cooling load, electric lighting needs, and electric lighting energy cost more than offset cost of installation.
energy savings
Energy Savings
  • Reduction in annual lighting energy of daylit spaces: 70%
  • Reduction in annual cooling energy: 19%
  • Increase in annual heating energy due to reduced internal heat from lighting: 20%
  • (cooling load > heating load in our region)
paying for daylighting
Paying for daylighting:
  • Construction cost: $1.23/ft²
  • Operation:
    • Annual lighting & cooling savings: $0.33/ft²
    • Annual heating cost increase: $0.04/ft²
    • Total annual energy savings: $0.29/ft²
  • Simple payback = 1.23/0.29 = 4.2 years
demand reduction
Demand Reduction:
  • Little electrical lighting on clear days.
  • Intermittent on/off cycling on overcast days
  • Few complaints about cycling
