CERTIFYCATION-new

A certification (environmental classification) is an assessment of how environmentally sustainable a building is. Based on a certification the building receives a certificate confirming its environmental performance.
  • A Passive house is an extremely well insulated building that is mostly heated by energy already available in the building. People and household appliances generate large amounts of energy.

    Widespread application of the Passive House design would have a dramatic impact on energy conservation. Data from the U.S. Energy Information Administration shows that buildings are responsible for 48% of greenhouse gas emissions annually and 76% of all electricity generated by U.S. power plants goes to supply the Building Sector. It has been abundantly clear for some time that the Building Sector is a primary contributor of climate-changing pollutants, and the question is asked: How do we best square our building energy needs with those of our environment and of our pocketbook? In the realm of super energy efficiency, the Passive House presents an intriguing option for new and retrofit construction; in residential, commercial, and institutional projects.

    A Passive House is a very well-insulated, virtually air-tight building that is primarily heated by passive solar gain and by internal gains from people, electrical equipment, etc. Energy losses are minimized. Any remaining heat demand is provided by an extremely small source. Avoidance of heat gain through shading and window orientation also helps to limit any cooling load, which is similarly minimized. An energy recovery ventilator provides a constant, balanced fresh air supply. The result is an impressive system that not only saves up to 90% of space heating costs, but also provides a uniquely terrific indoor air quality.

    A Passive House is a comprehensive system. “Passive” describes well this system’s underlying receptivity and retention capacity. Working with natural resources, free solar energy is captured and applied efficiently, instead of relying predominantly on ‘active’ systems to bring a building to ‘zero’ energy. High performance triple-glazed windows, super-insulation, an airtight building shell, limitation of thermal bridging and balanced energy recovery ventilation make possible extraordinary reductions in energy use and carbon emission.

    Today, many in the building sector have applied this concept to design, and build towards a carbon-neutral future. Over the last 10 years more than 15,000 buildings in Europe – from single and multi-family residences, to schools, factories and office buildings – have been designed and built or re-modeled to the passive house standard.

    KKA has designed approximately twenty passive houses, of which five are built.

  • BREEAM (BRE Environmental Assessment Method) is the leading and most widely deployed sustainability certification in the world, for buildings and urban plans. It sets the standard for best practice in sustainable design and has become the de facto measure used to describe a building’s environmental performance. BREEAM provides clients, developers, designers and others with:

    • market recognition for low environmental impact buildings
    • assurance that best environmental practice is incorporated into a building
    • inspiration to find innovative solutions that minimise the environmental impact
    • a benchmark that is higher than regulation
    • a tool to help reduce running costs, improve working and living environments
    • a standard that demonstrates progress towards corporate and organisational environmen-tal objectives

    BREEAM addresses wide-ranging environmental and sustainability issues and enables developers and designers to prove the environmental credentials of their buildings to planners and clients. It:

    • uses a straightforward scoring system that is transparent, easy to understand and supported by evidence-based research
    • has a positive influence on the design, construction and management of buildings
    • sets and maintains a robust technical standard with rigorous quality assurance and certification

    Kjellgren Kaminsky Architcture is the first architectural firm in Sweden that has designed a renovated building as a certified BREEAM project with the level of: Very Good.
    Fredrik Kjellgren is responsible for project planning with BREEAM certification.
