HRV for redevelopment

HRV systems, energy requalification of buildings and healthiness

The market for real estate renovations and redevelopments has seen a real boom in recent years. Thanks also to the decarbonisation objectives at European level, a process of evolution and modernization of the existing building heritage is underway.

In energy efficiency interventions, especially with thermal insulation, it is essential to provide a mechanical ventilation system. In fact, the building’s high air tightness performance, given by the insulation of the envelope and the replacement of the fixtures, risk creating air stagnation problems in the absence of adequate and frequent ventilation.

Solve condensation, mold and indoor pollution problems

Poor or inadequate ventilation, i.e. the absence of regular and frequent air exchange in indoor environments, can cause various problems:

• Perception of stale air
• Condensation phenomena in critical points
• Formation of mold
• Malaise and drowsiness from excess CO2
• Accumulation of dust, allergens and pollutants such as VOCs

A HRV for building redevelopment with external insulation

The conversion of existing assets requires a design that takes into account energy performance without neglecting the quality of the air in increasingly hermetic environments. Air exchange systems with heat recovery are an essential ingredient to ensure a comfortable and healthy environment while respecting energy saving objectives.

Helty, which over the years has perfected a range of decentralized HRV solutions ideal for the redevelopment market, has designed a one-of-a-kind punctual ventilation system, designed for installation at the same time as the external cladding: Flow Manhattan.
