This case study examines how building design and glazing contribute to energy efficiency. It highlights the effectiveness of using optimized glazing solutions that include factors like solar control and insulation, resulting in significant energy savings and a quick return on investment. The findings demonstrate that strategic orientation and shading can enhance energy performance while allowing for relaxed glass specifications.
Optimal building design and glazing
- 1. AIS Optimal Building Design and Glazing Case Study
- 2. AIS This Case Study focuses on the relation of a building’s design with its achievement of energy efficiency through glazing. Introduction
- 3. AIS Glazing solutions • Normally, glazing solutions for energy efficiency make use of glass with a lower Solar Factor and lower U- Value. • It is successfully achieved energy efficiency using glass with an optimum Solar Factor and U-Value and higher VLT because of its optimal building design. • As glazing solutions are expensive, this meant big cost-savings and quicker recovery of investment.
- 4. AIS • Classrooms located on the north side received diffused light and no direct heat. • South-facing classrooms were provided with a shading device to prevent direct heat and glare. • Buffer zones, created by placing the service areas along the east façade and corridors along the west façade, prevented heat ingress in the offices. HEAT SOLUTION
- 5. AIS • Walls had good insulation properties to prevent long-wave radiations from entering into the building. • North light provided natural light to a portion of the building

- 8. • A detailed building energy analysis was conducted wherein various AIS products were considered, (Performance parameters given in Table 1.) • As shown in Fig 2, Spring SGU (Solar Control product from the Ecosense range) which has Solar Factor (SF) = 64%, Visual Light Transmission (VLT) = 65%, • And U-Value = 5.4 w/ m2k performs best out of all the glasses with 17% energy savings and 2 months’ payback period, when compared to base case Clear DGU (double glaze unit). The resultAIS
