Double story or two story homes have many advantages. Liberty in choosing a floor plan as per your needs, spaciousness, storage, separation of living areas are some of its benefits. But a downside of these homes could be huge heating and cooling cost. If you are a duplex home lover and desires to build an energy efficient house, here are latest technologies and architectural trends to incorporate -
7 Latest Energy Efficiency Trends
- Green Roofing for 2-Story Homes
Green roofing is an easy and effective strategy for beautifying your home as well as it increases the homes resale value. Green roofs help to reduce the amount of energy needed to moderate the temperature of a building. Research published by the National Research Council of Canada found that green roofs can reduce the daily energy demand for air conditioning in the summer by over 75% (Liu 2003) and are able to cool cities during hot summer months and reduce the Urban Heat Island effect.
- Cool Roofs - Alternative Materials
Cool roofs are made from reflective materials (tiles, shingles, paint, etc.) that reflect sunlight and lower roofing temperatures. This energy-saving technique is best for warm climates where air conditioning costs are high all year around.
- Skylights In Two Story House Plans
Skylights are one of the most sought features in terms of improving homes' energy efficiency. Skylights have many benefits like - improving houses' heating, lighting and ventilation.
- Light Exterior Colors
A light exterior color will help the home stay cooler, whereas a darker shade will trap heat. Hence, homes in a warm climate must prefer a light-colored exterior and that in colder climates should opt darker outdoor shades.
- Options for Flooring
The type of flooring can largely help in saving energy and money. Carpet and rugs can trap heat and keep your home warmer. Natural materials such as stone, clay, timber, marble, granite and concrete flooring work best to keep homes cool during summer and warm in winter.
One of the greatest sources of heat gain in homes is unprotected glass, particularly for those who live in the hotter parts. By simply shading this glass with awnings, shutters or pergolas, one can dramatically reduce the heat load from direct sunlight.
- Passive Home Design
Passive home design helps to take the advantage of your environment to maintain a comfortable temperature. It helps to save up-to 40% off your energy use.
- > Passive Cooling
Passive cooling can effectively eliminate the need of AC when combined with shading.
“Natural ventilation, also called passive ventilation, uses natural outside air movement and pressure differences to both passively cool and ventilate a building. It can include design strategies like wind ventilation, the stack effect, and night purge ventilation.” Source: sustainabilityworkshop
- > Passive Solar Heating
For cooler climates, heating homes in winters can be notoriously expensive. Passive solar heating locks the heat in winter sun and creates a building envelope that keeps heat inside during winter. This reduces expense and damage to the environment.
