Energy Efficient Homes

You may have heard of the phrase ‘Net-Zero Energy Building (NZEB)’ or ‘Zero Energy Building (ZEB)’, these are concepts that move us closer to a renewable energy future as it applies to residential and commercial buildings. All new buildings in California will need to meet the Zero Net Energy standard starting in 2020 for new residential constructions.
 
Passive House Institute (PHI) has developed a very low energy construction standard reduction by 90% the heating and cooling load. Recent PHI research has  introduced to the existing standard Passive House ‘Classic’ 2 additional classes taking renewable energy into consideration: Passive House Plus and Passive House Premium. 

This equitable assessment of energy  will help to guide us towards 100% renewable energy future in California and eventually the whole nation. All of the new Passive House standards now calculate Primary Energy using Primary Energy Renewable (PER) factors.  These are designed to encourage the use of renewable energy sources.

To achieve net-zero Energy, a building team first reduces use as much as possible the heating and cooling loads using the Passive House principals: continuous insulation, airtightness, high efficiency windows,


thermal bridge free and a proper ventilation system. Then to account for planned energy use, the building team focuses on planning for and utilizing sufficient renewable energy sources like solar panels, solar hot water and wind power.

​Currently only an estimated 1% of commercial buildings are built to net-zero energy criteria. One reason for this small number, according to National Renewable Energy Laboratory or NREL’s researchers, is the diffuse nature of the commercial building sector, which makes it difficult for new research to reach and impact the buildings market.  As a result, many practitioners in the commercial buildings sector remain unaware of the accessibility of net-zero annual energy design, assuming that it is too expensive.
We at Nico Designs are currently in the process of building and retrofitting a Passive House designed home in Los Angeles, if you are interested in learning more about this concept and make California a greener state, please contact us for a free consultation meeting.
