The Problem of Energy Inefficiency in Buildings

The building sector presents an alarming reality today. Buildings are responsible for 37% of total global carbon emissions, which makes them major contributors to our climate crisis. A deeper analysis of the data reveals that building operations alone account for 30% of global final energy consumption and 26% of global energy-related emissions.

Statistics on building emissions

These numbers reveal a significant challenge in the building sector. The building sector’s total greenhouse gas emissions reached 12 GtCO2-eq in 2019, which made up 21% of global emissions. The situation looks more serious because global CO2 emissions from buildings rose by a staggering 50% between 1990 and 2019.

Common sources of energy leakage

Air leakage stands as a major cause of wasted energy in buildings. Several critical areas contribute to this energy loss:

• Building Envelope Issues: Buildings lose air through uncontrolled flow between outside and inside via cracks and fissures
• Heat Loss Through Infiltration: Buildings can lose 20% to 50% of their total heat through infiltration and exfiltration
• System Inefficiencies: HVAC systems, plumbing penetrations, and poorly sealed access points create significant problems

Effect on climate change

Climate change continues to have substantial and growing effects. Buildings must become energy efficient to solve the climate crisis. The quickest way to tackle climate change and reduce energy waste is through efficiency measures, and with good reason too.

Buildings present unique challenges because they rely on hard-to-abate industrial sectors like steel and cement. But energy-efficient designs and systems lead to major cost savings across the value chain. To name just one example, see how high-efficiency heating and cooling systems paired with advanced energy management deliver remarkable results. Beijing’s Taikoo Li Sanlitun’s air-conditioning upgrade cut energy use by 66%.

These inefficiencies need urgent attention. Buildings generate over one-third of global energy consumption and emissions, which calls for immediate action. The building sector’s energy needs grew by nearly 1% in 2022 compared to 2021, showing how this challenge keeps growing. Net-zero emissions require a 9% yearly drop in emissions until 2030 – a target that needs groundbreaking solutions right now.

Aeroseal: A Breakthrough Solution

A groundbreaking innovation in green technology has caught our attention with its revolutionary approach to building efficiency. Aeroseal, recognized as a proven air sealing solution in 30 countries, leads the way in building science. The U.S. Department of Energy praised this patented technology as “one of the best scientific and technological accomplishments since this department was first established”.

How Aeroseal’s technology works

Aeroseal uses a unique approach that tackles air leaks from the inside out. The technology combines a water-based, non-toxic solution with a pressurized system that warms and distributes it effectively. This impressive system knows how to detect and seal even the tiniest air leaks, which helps improve energy efficiency and indoor comfort.

The polymer sealing process

The precision and effectiveness of this sealing process amazes me. Let me explain how it works:

• The system starts by pressurizing the ductwork. Computer tools analyze and pinpoint all leaks
• Adhesive particles get injected and stay suspended in the airflow
• The escaping air pulls these particles toward the leak edges. They accumulate and create a complete seal

This innovative process seals leaks up to 5/8 inch wide. The sealant works with such precision that only 1-2 ounces stay in the ducts after completion. The computer-monitored system provides up-to-the-minute data analysis that tracks the sealing progress throughout the operation.

Applications in air ducts and building envelopes

Aeroseal’s versatility amazes us in both residential and commercial applications. This technology works exceptionally well in two key areas:

1. Duct Sealing: The system seals up to 99% of duct leakage without damaging walls. Traditional methods only seal 5-10% of existing duct leakage.
2. Building Envelope Sealing: The technology delivers impressive results in building envelopes.

This technology’s benefits go beyond energy savings. The sealing process needs minimal material and fits into standard construction schedules easily. The sealant takes just 60 to 90 minutes to apply and dries before equipment cleanup ends. This makes it the quickest way to seal both new construction and renovation projects.

Aeroseal increases building tightness by 75-85% above the newest energy code requirements. These performance levels and simple implementation make it a revolutionary solution for environmentally responsible building standards.
