A Passive House will have:
- Proper insulation
- No air leakages
- No thermal bridges
- Highly energy efficient windows
- Orientation and shading to take advantage of sun and shade in terms of heating and cooling
- Use of heat recovery ventilation to moderate heating and cooling
- Increased energy efficiency by up to 90 per cent compared to a conventional building, resulting in lower heating bills.
Cygnum employs two qualified and highly experienced Passive House designers – contact us now for more information.
Airtightness is the resistance to air unintentionally leaking in or out of a building through leakage points around its structure, between its internal and external surfaces.
An airtight building such as a timber frame home will result in lower heating bills, and have a well-performing ventilation system and fewer draughts.
The carbon footprint of a building is the total amount of CO2 (carbon dioxide) produced and emitted, directly and indirectly (eg embodied in all of the processes involved in manufacturing a product or producing a service) in its construction.
If a building with a low carbon footprint is your priority, Cygnum’s team of qualified and highly experienced specialists can help you achieve it.
Building Energy Rating
A Building Energy Rating (BER) is an indicator of the energy performance of a building.
BER is the calculated energy use for space and hot water heating, ventilation and lighting, based on standard occupancy.
The label has a scale from A to G, with A-rated homes being the most energy efficient, tending to have the lowest heating bills.
Building a Cygnum timber-frame home is the most financially and environmentally sound way of achieving the lowest possible BER for your dream home or next project.
It is estimated that up to 30% of the heat loss in a well-insulated building occurs where materials that are poor thermal insulators come into contact, allowing heat to flow through them.
Example: a balcony that extends a steel reinforced concrete floor (which is also the highest part of the ceiling of the room below) allows heat to transfer from inside to outside.
A well-designed timber frame building minimises thermal bridges and may feature none at all.
