Fresh Air Heat Recovery Ventilation

The lack of natural ventilation due to airtight spaces can lead to the build-up of moisture-laden stale air within the home. This is the perfect breeding ground for mould that can trigger allergy or respiratory problems.

Common places for mould to grow include window sills, curtains, carpets and walls. Controlling moisture and humidity levels in the home through constant ventilation is seen as the most important step you can take to ensure your home remains healthy, drier and mould free all year round.

Lossnay effectively helps to reduce moisture from your home by constantly bringing in fresh filtered air from the outside (not attic air) and directly removing damp stale, stagnant air that causes condensation. Furthermore Lossnay not only effectively manages humidity levels for better health and well-being, it also recovers heat energy from the stale outgoing air at the same time. This is then used to pre-heat (or cool) the incoming fresh air, maximising energy efficiencies.

Why choose Lossnay?
Mitsubishi Electric’s Lossnay Fresh Air Ventilation systems are designed in Japan for New Zealand conditions, featuring our patented Heat Exchanger options (the secret to either the Heat, or Total Energy Recovery capabilities our Lossnay units provide). Because Lossnay uses fresh air (not attic air) to ventilate your home, you get the best of both worlds – fresh air into the home whilst reducing dampness, without the excessive added heating costs that most alternative systems cannot prevent. Lossnay ensures the air in your home stays fresher, cleaner and drier. By recovering indoor heat you will also increase energy efficiency.

Lossnay is Designed for Today’s Modern Homes
The word “Lossnay” originated from the Japanese word “Loss-Nai”, meaning “No Loss”. Lossnay is a patented Balanced Pressure Heat Recovery Ventilation System ideal for more airtight homes built to the current New Zealand Building Code. Using Lossnay Ventilation Systems can achieve compliance with the Ventilation Standard NZS4303:1990 that specifically requires ventilation systems to draw fresh air from the outside and not the roof space to achieve acceptable indoor air quality.

Ventilation and Airtight Building Design
Creating a healthy living environment is important when renovating or building a new home – you will want the perfect indoor climate year-round. In addition to efficient heating and cooling, this should include the optimum amount of fresh air.
Current building regulations now demand homes to be built more airtight as they are subjected to higher insulation standards. The option of leaving doors or windows open to allow more fresh air to enter is often not the solution from an outdoor noise or security perspective.

Ventilation, Condensation and Moisture Management
The lack of natural ventilation due to airtight spaces can lead to the build-up of moisture-laden stale air within the home and creates the
perfect breeding ground for mould that can trigger allergy or respiratory problems. Mould and dampness can compromise both building materials as well as furnishings inside the home. Common places for mould to grow include window sills, curtains and carpets.

Energy Efficient Operation
Ventilating our indoor spaces is more important than ever, but we also need to be as energy efficient as possible. The new Vertical Lossnay will deliver filtered indoor air whilst recovering energy to minimise waste. Infact, Lossnay’s unique heat recovery technology recovers up to 85% of the heat energy from the outgoing stale air which is then used to pre-warm (or pre-cool) incoming fresh air.

The Lossnay Core
The Balanced Pressure Lossnay Heat Recovery Ventilation System removes stale, dirty air and draws in fresh air from outside. Lossnay also recovers heat energy from the air being transferred to pre-warm (or pre-cool) the fresh air being drawn into your home. Lossnay is ideal for small to large sized homes between 52m2 and 400m2.
