Minimum energy performance

Key contribution

ISOVER offers the broadest range of insulation solutions directed at energy efficiency, allowing you to make significant energy savings in heating and air conditioning.

Aim

To reduce the environmental and economic harms of excessive energy use by achieving a minimum level of energy efficiency for the building and its systems.

Detailed requirement

Option 1 “Whole-building energy simulation”:

Demonstrate a 5% improvement (for new construction) in the proposed building performance rating compared with the baseline building performance rating (using ANSI/ASHRAE/IESNA Standard 90.1–2010 to make the simulation). A USGBC-approved equivalent standard for projects outside the U.S. may be used.

Option 2 “Prescriptive compliance”: ASHRAE 50% Advanced Energy Design Guide

Comply with the mandatory and prescriptive provisions of ANSI/ASHRAE/IESNA Standard 90.1–2010, with errata (or a USGBC-approved equivalent standard for projects outside the U.S.).

Option 3 “Prescriptive compliance”: Advanced BuildingsTM Core PerformanceTM Guide

Comply with the mandatory and prescriptive provisions of ANSI/ASHRAE/IESNA Standard 90.1-2010, with errata (or USGBC approved equivalent standard for projects outside the U.S.).

Our contribution

Buildings account for some 40% of energy use in developed countries, so: there is huge savings potential in making them more energy efficient. Heating and cooling account for two thirds of buildings’ total energy consumption.
A large amount of this energy is typically wasted due to a poorly insulated building envelope that lacks air - tightness.

Insulation is the most cost effective way to reduce energy consumption in buildings and cut associated greenhouse gas emissions. The most inexpensive energy is the one that is not consumed in the first place. It does not need to be generated, imported, or paid for. Naturally, this also doesn’t have any harmful effects, either on human beings or the environment.

Compared to an uninsulated building, an insulated construction ensures up to 80% reduction in energy consumption.
