CHARACTERISTICS
A healthy and sustainable house is healthy for it's occupants and the global environment and encompasses these main characteristics:
- Occupant health
- Energy efficiency
- Resource efficiency
- Environmental responsibility
- Affordability
- Sustainability
- Self-sufficiency
This house can be built anywhere as it does not depend on any services such as hydro, sewer, water, etc. When we build and/or renovate, we may or may not implement all of the characteristics of the Healthy and Sustainable House. The point is to be aware of this potential, and to know that we are at choice.
Characteristics of the Healthy and Sustainable House:
Occupant Health
Air quality through reduction-elimination of source emissions, and high efficiency ventilation-heat recovery system. Exterior vented central vacuum system.
Water quality through filtration, reverse osmosis, iodization, distillation, ultraviolet irradiation and ozonation
Natural and full spectrum lighting
Reduction of noise, electromagnetic fields (EMF) and radon gas
Usage of household plants helps remove common indoor airborne pollutants
Natural building materials and furnishings: low emission wool rugs, sofas-chairs made of untreated cotton and hardwood frames
Eliminate dust emitted from concrete floors by sealing them with a non-toxic water based sealer
When renovating the indoors, set-up a temporary ventilation strategy to protect all occupants
Gardening for organic fruits and vegetables all year round
Combustion air directly from outside, and all combustion appliances are sealed off the house, and a carbon monoxide (CO2) detector
Optimum air filtration
Chemical free insect/pest control
Energy Efficiency
Implement renewal power source program as much as possible
High efficiency radiant solar heated hot water heating system
Maximum insulation levels in walls and attic included in the maximum building envelope
Energy efficient appliances
Insulated hot water pipes
High efficiency windows and doors
Energy efficient lighting, compact fluorescent halogen bulbs
Large amount of windows and skylights, strategically placed for passive solar heating and lighting (30% of annual space heat)
Minimal or no electricity consumed from hydro
Solar photovoltaic thermopile and battery storage system, in the renewable power source program
Resource Efficiency
Natural water purification mimicking nature when it passes through the ground to a spring
Water conservation measures (Low flush toilets, etc.)
Efficient use of building material
Expand usage of recycled and re-used building materials
Use of domestic growing woods like spruce and maple
Locally produced materials
Durability of house components
Drip irrigation system and cistern collecting water for watering garden and domestic usage
Reducing embodied energy by 40% from currently 30 years
Automatic controls for furnace, air conditioner, heat recovery system
Environmental Responsibility
Reduce, eliminate fossil fuels usage, thus having less carbon dioxide emissions which affects global warming
Solar radiant floor and ceiling space heating
Natural cooling
Recycling of old building materials
Recycling centre in the kitchen
Build smaller spaces that are efficient-efficacious, thus using less resource and waste
Composting
Low in watering 2.5cm (1") per week. Do not over water. Also, plant drought resistant native plants and grasses.
Home office, to reduce travelling
Waste water and sewage treatment on site
Community and site planning
Management, reduction, elimination of hazardous materials
Affordability
Use of products readily available
Flexible designs to reduce future renovation costs and readily adaptable to multi-usage
Low maintenance long lasting materials
High indoor air quality, for happier life and lower health care costs
Energy efficiency for lower operating costs
Compact, efficient spaces for affordable up-front costs
