When Norbert and Robin were designing their retirement dream home in southeastern New Hampshire, they were inspired by the concept of dynamic energy efficiency. Four energy-efficient systems were used to ensure comfort throughout the year while promoting indoor air quality.
Think for a moment about how the experience of breathing fresh air cleans your mind, calms your mood, and revitalizes your body. Now imagine that feeling every minute in your home, the temperature is comfortable, and that freshness is always there.
Last month I attended the conference of the North American Passive House Network in New York City. Here are the three products that most caught my eye at the NAPHN passive house conference.
Homes are being more tightly built than ever to prevent air leakage and promote energy efficiency. High humidity levels can encourage mold growth, and indoor pollutant levels are commonly two to five times higher than outdoors, compromising health.
Although people may feel healthy despite exposure to pollution, Lyme disease or other illnesses can act as a trigger, significantly degrading health.
Property assessed clean energy (PACE) is a means of finance energy-saving home improvement projects in California through property tax bills, making it affordable to many homeowners. Air sealing a home can, however, cause air quality issues to arise, increasing the importance of mechanical ventilation.
The quality of the air inside of offices, retail stores, restaurants and other types of workplaces can have an impact on the health and comfort of the workers. Fortunately, there are steps that can be taken to improve indoor air quality in workplaces.
Although it is commonly known that poor indoor air quality can cause major health issues such as asthma and lung cancer, it is a less known fact that it can degrade productivity, the ability to concentrate, energy levels, and even mood.
According to a recent study published by Environmental Health Perspectives, associations between ventilation and cognitive function were found to be quite strong.
Many historic neighborhoods across the United States are being renovated and revived. When done effectively, both charm and history can be captured, while making the homes more energy efficient.
When Norbert and Robin were envisioning a retirement home, they aspired to live in a high-performance home, powered by renewable energy. This would help protect them from unpredictable energy costs in the future.
When building a new home, design and material selection greatly impact the operating costs for decades. Is it financially savvy to construct a super efficient home over a code-built home because of the reduction in operating costs?
The core of heat recovery is the heat exchanger. There are various types of heat exchangers available including cross-flow, counter-flow (includes rotary/wheel) and cross-counter-flow.
With the cold temperatures of winter descending upon most areas of the United States, there is a desire to keep as much heat as possible in the home. Ventilation systems can sometimes make it difficult to retain the heat in the home.
There are many green building guidelines, programs, standards and certifications available in the US and Canada. The best green building approaches cover many elements of the building such as energy efficiency, water efficiency, resource efficiency, responsible site management and improved indoor air quality.
High and low levels of relative humidity within the home can have adverse effects for the occupants as well as the dwelling itself. Hygiene, health, retention of value, aesthetics and comfort are all areas which can be affected by a failure to maintain an optimal level of relative humidity.
Proper ventilation is a critical consideration for homes and buildings. Poor ventilation can cause a buildup in indoor air pollutants like dust, pollen, mold, and household chemicals. An efficient and reliable ventilation system works to remove polluted air while continuously introducing fresh, clean air.
Ventilation strategy at Proud Green Home of St. Louis is key to increased air quality, comfort, and durability
The Zehnder system provides a constant air flow bringing in fresh air from the outside and exhausting stale air from the inside at a very low velocity so it is hardly noticeable
