Grocery shopping analogyHow much would you spend on groceries if you only got the bill at the end of the month? How much energy do you use?
Kwh per month?
Kwh per day?

Insulated Concrete Form (ICF)• is a system of formwork for
concrete that stays in place as permanent building insulation for energy-efficient, cast-in-place, reinforced concrete walls, floors, and roofs.
• Needs exterior and interior finishing.
• Resistant to hurricanes, also earthquakes if reinforced.

Infiltration
• Infiltration is the unintentional or accidental introduction of outside air into a building

How to prevent mold and save money

Variable Refrigerant Flow Systems
• They can provide thermal comfort for building occupants. In order of importance:1. Ventilation2. Humidity Control3. Cooling
• VRF is easier to design and offers space-saving features. Its modular format lends itself to phased installations.
• Humidity Control – by actively controlling the humidity and temperature at the same time, mold growth can be prevented. Traditional air conditioner systems overcool the spaces in order to remove the humidity.
• Energy Efficiency – the compressors on these units vary the speed up and down to meet the requirements, keeping the space at constant conditions and preventing duct loss.
• Zoned Comfort - each individual zone can have personalized comfort.• Quiet Operation – many Indoor and outdoor units are very quiet so they can be
placed just about anywhere.• Lower Lifecycle Cost - operate with minimum energy usage. Only service the
zones that need it, which allows for less required maintenance.

Energy Efficiency & Renewable Energy can help
• Incandescent light bulb = 40 watts/hour $2 life 20,000 hours• =
• LED light bulb = 8.7 watts (40 watts equivalent) /hour at $18 life 50,000 hours
• =$200.7
• Renewable energy (solar) = $6 watt installed @ 20% efficiency
• In order to power 40 watt light bulb @ 20% efficiency 200 watts are necessary = $1200 vs. $261
• Total costs $1205 vs. $279

Rent or Own?
Own• If you plan to keep the home
and appliances for just a few years it makes sense to invest.
• The initial investment is steep, but return on the investment is better than keeping the money in the bank.
• Some financial incentives are available: rebates, loans, tax credits.
• The value of the building will also go up.
Rent• When entering into a lease,
request an energy assessment of the property.
• When renewing a lease, negotiate with the landlord, it benefits both if the usage is the same.
• Landlords can set electricity consumption limits for leases with power included.
