Energy Reductions

It is important to note that Passive House achieves huge energy reductions through high-tech, cutting edge design – not by sacrificing comfort.
Through the careful craftsmanship, specification of insulation, selection of better windows and the use of heat recovery ventilation, the energy consumption of a building can be reduced by up to 90% while maintaining, or more often than not, increasing the comfort of internal spaces.

Cost Effective

Unlike traditional buildings which can be energy-hungry beasts requiring costly heating and cooling throughout the year – once built Passive House construction requires very little energy to operate comfortably.

Even so, Passive House buildings can be surprisingly affordable to build – the cost of higher spec windows, insulation and ventilation, is often offset by the ability to install more modest heating and cooling systems. So far our projects have cost the same as typical construction – and once it’s complete you’re set to enjoy long term savings as the operating cost of the building year on year is reduced significantly.

More Comfort

Occupant comfort is at the forefront of Passive House design – as it is the benchmark against which the success of the building is measured. Throughout the design of these buildings every detail is carefully considered as to how it effects heat loss or gain, and therefore the comfort of the occupant. The goal is to meet this benchmark without the need to waste energy on unnecessary mechanical systems. The exclusion of these systems, combined with a carefully detailed, high-tech building envelope ensures that Passive House buildings provide the most comfortable, quiet, and draft-free environments.

Healthier Environments

In traditional houses air is filtered through the walls, which can contain mold, pollutants and allergens. In comparison the envelope of a Passive House is carefully sealed and heat recovery ventilation systems provide a steady flow of filtered air while exhausting stale air from service spaces. These high-spec envelopes also eliminate cold bridges, which can lead to condensation and the growth of mold.

By ensuring of air-tightness, continuous insulation and heat-recovery ventilation systems, Passive Houses can greatly contribute to providing clean, containment free environments.
