why do we need energy efficient housing
It may seem like a strange question, why build an energy efficient home, but nevertheless, there are some people out there who are asking it. The case for energy efficient homes is pretty straightforward. They provide their owners with:
In addition to the reasons listed above, an is also better for the environment; for example, 16% of all greenhouse gases produced in the United States come from residential dwellings. As the economy continues to struggle, many homeowners в and homebuyers в in their search to reduce costs, are becoming more aware of the benefits of energy efficient homes, which is why the demand for them has increased significantly. As a result, homeowners are getting their houses rated for energy efficiency in order to understand where they rank and what they need to do to improve. The вs (RESNET) (HERS) is the nationally recognized system for inspecting and calculating a home s energy performance.
When a conducts an energy rating, it results in a for that home, based on its energy performance. The HERS Index is the industry standard by which a homeвs energy efficiency is measured. The way it works is: A certified RESNET HERS Rater assesses the energy efficiency of a home, assigning it a relative performance score. The lower the number, the more energy efficient the home. The U. S. Department of Energy has determined that a typical resale home scores 130 on the HERS Index while a standard new home is awarded a rating of 100. And the HERS Index Score is like a MPG (miles-per-gallon) sticker for houses. It lets a in comparison to other similar homes. The next question is once youвve decided to build an energy efficient home, how would you do it? As it happens, builders are doing just that в building energy efficient homes. Because demand is rising, increasing numbers of builders are entering into Memorandums of Understanding (MoUs) with RESNET to have their.
Buyers can then compare houses based on HERS Index scores, allowing them to make informed decisions about homes they want to purchase. When you look at all the facts, the answer to the question of why build an energy efficient home is simple really: because itвs the smart thing to do. More broadly, we need to realise that a high thermal performance home (with good insulation, draught proofing and well-designed glazing) above the outdoor temperatureБ in both winter and summer. Extra internal mass or phase-change materials can help to stabilise the temperature, duration of hot spells, so thermal mass is becoming less effective. The houses they built up here in FNQ are mostly timberframe/steelframe with insulation in the walls. Outside is usually some sort of cladding like hardiflex or even worse brick veneer (thermal mass outside). I don t know if they put insulation into the ceiling, but it s definitely under the roof sheeting, which doesn t help avoiding heat build up under the roof.
Next thing then are standard air cons without any humidity control, unless you can do with the ac at 19 deg to get the humidity out П Oh and the roof layout on modern homes is the most idiotic thing of it all. I mean, just look at google earth and see for your self how stupid most of them are as the roof is so jagged up into small pieces that go into all directions so you won t be able to fill it efficiently with solar panels. total madness this. My dream home would be made from internal concrete wall, nice insulation on the outside with hardiflex on top and a flat roof, no eaves (two story) and a HAVC system for the whole house that extracts heat/cold from the air it exchanges with the outside (recuperation) at 90% efficiency. Heating or cooling something like that will be easy peasy.
