### MLI Select mortgage loan insurance

MLI Select is a multi-unit mortgage loan insurance product that prioritizes affordability,
accessibility, and environmental friendliness. It operates on a point system, providing
insurance incentives that are determined by affordability, energy conservation, 
and accessibility. These incentives apply to both newly constructed and existing
properties. The more dedication you show towards social and environmental results,
the greater the rewards.

Only professionals such as engineers, architects, Certified Engineering Technicians(
CET), or Certified Energy Managers (CEM) are qualified to create an energy model
that complies with the requirements.

### BLOWER DOOR TEST

The blower door test is a diagnostic tool used by our energy advisors to measure
a home’s airtightness. During this test, a powerful fan is fitted into an exterior
doorframe and temporarily seals all other openings, such as windows and vents. The
fan then either depressurizes or pressurizes the house, causing air to flow through
any gaps, cracks, or openings. The primary goal of this test is to detect air leaks,
which helps reduce energy consumption and enhance home comfort. Additionally, the
blower door test provides data on air changes per hour (ACH) and the equivalent 
leakage surface (ELS), allowing comparison with other homes built during the same
era.
