The goal of building High Performance properties is to reduce energy usage and increase the use of sustainable materials. Air tight construction is of primary importance, we work to limit the volume of air infiltration, provide exceptional insulation, healthier buildings and reduse annual energy useage.
WHAT IS “LEED” (Courtesy US Green Building Council)
LEED, or Leadership in Energy & Environmental Design, is a third party certification program and the nationally accepted benchmark for the design, construction and operation of high performance green buildings. Developed by the U.S. Green Building Council in 2000 through a consensus based process, LEED serves as a tool for buildings of all types and sizes. LEED certification offers third party validation of a project’s green features and verifies that the building is operating exactly the way it was designed.
To receive LEED certification, building projects satisfy prerequisites and earn points to achieve different levels of certification. Prerequisites and credits differ for each rating system, and teams choose the best fit for their project.
WHAT IS “NETZERO”
A zero-energy building, also known as a zero net energy (ZNE) building, net-zero energy building (NZEB), or net zero building, is a building with zero net energy consumption, meaning the total amount of energy used by the building on an annual basis is roughly equal to the amount of renewable energy created on the site. These buildings still produce greenhouse gases because on cloudy (or non-windy) days, at night when the sun isn't shining, and on short winter days, conventional grid power is still the main energy source.
Traditional buildings consume 40% of the total fossil fuel energy in the US and European Union and are significant contributors of greenhouse gases. The zero net energy consumption principle is viewed as a means to reduce carbon emissions and reduce dependence on fossil fuels and although zero-energy buildings remain uncommon even in developed countries, they are gaining importance and popularity.
WHAT IS “PASSIVE HOUSE” (Courtesy Passive House Alliance, US)
Passive House is both a building energy performance standard and a set of design and construction principles used to achieve that standard. The passive house standard is the most stringent building energy standard in the world: buildings that meet the standard use 80 percent less energy than conventional equivalent buildings, and provide superior air quality and comfort.
A systems-based design strategy carefully models and balances a comprehensive set of factors including heat emissions from appliances and occupants--to keep the building at comfortable and consistent indoor temperatures throughout the heating and cooling seasons. Continuous mechanical ventilation of fresh filtered air, assures superb air quality.
