The following case studies are compiled from the ESEC Building Energy Services WeChat official account and on-site project records


“The sunlight is still there, but the heat and harsh glare have been quietly kept outside the window.”—— Client feedback at on-site acceptance
Untreated Side · Harsh, Glaring Sun
After Installation · Soft and Comfortable
Shot in the same private office at the same moment: the treated side is evenly lit and soft, while the untreated side is washed out by direct sunlight. No instruments needed — the difference is plain to the eye.
Certified crews · Standards-compliant work
Precision installation · A perfect fit
Certified crews for work at height and zero-damage installation in finished interiors. Once delivered, the window curtain blends seamlessly with wood paneling and greenery (see completed project photos on our About Us page).
Before Installation · Direct West-Facing Sun
After Installation · Clear and Comfortable
Half-lowered window curtain on a curved floor-to-ceiling curtain wall: heat and glare stay outside the glass, bedding no longer feels scorching, and the city view remains clear — the room that drew complaints now earns praise.
