Many people wonder how they can integrate a skylight into their metal roofs, and whether the investment really pay off. The answer is yes!
Lighting plays a vital role in workers' performance and attitude, and incorporating natural light has proven to be a smart move with a fast return on the investment.
Let's examine a couple of cases:
Production hall, Haifa, Israel
This production hall used to be illuminated during the day with artificial lighting.
It took 60 projectors to light the work area during the day, as it is covered with industrial insulated panels.
The 3,000m² (32,300 ft²) hall includes production and logistical areas that operate 7 days a week and require full and uniformed lighting throughout the workday.
Project description:
| Structure type | Production hall |
| Size | 3000m² |
| Roofing system | Industrial insulated panels |
| Solution | SUNBOX factory assembled insulated skylights |
| Light intensity before SUNBOX | 600 LUX |
To introduce natural sunlight without losing the thermal insulation properties, SUNBOX insulated skylights were chosen:
10% of the roof area was replaced by the SUNBOX skylight system. This led to a reduction in the electric bill of more thanUS$7,000 annually.
The $19,860 investment was returned within 32 months. The projected lifetime of the system is 20 years.
Results:
| Skylight area of the roof | 10% |
| Annual power saving | US$7,586 |
| Cost of SUNBOX insulated skylights system | US$19,860 |
| Light intensity with SUNBOX | 1,100 Lux |
| Period required for ROI | 32 months |
With its flexibility, the SUNBOX system fits a wide range of regional specifications, taking into account the corrugated roofing panels' model, the level of light required, the desired insulation properties, the roof structure, and the given budget.
Above all, the environmentally friendly system enables financial savings and an improved work environment.
Storage warehouse, Mexico City, Mexico
This 5,500m² (59,200 ft²) warehouse was covered entirely with industrial insulated panels.
To introduce natural sunlight into the work area, a SUNBOX insulated skylights system was specified replacing 12% of the roof area.
Project description:
| Structure type | Warehouse |
| Size | 5,500m² (59,200 ft²) |
| Roofing system | Industrial insulated panels |
| Solution | SUNBOX Lite, factory assembled insulated skylights |
| Light intensity before SUNBOX | 550 LUX |
Annual savings of more than US$10,000 led to a ROI within 26 months!
Results:
| Skylight area of the roof | 10% |
| Annual power saving | US$1,320 |
| Cost of SUNBOX insulated skylights system | US$2,800 |
| Light intensity with SUNBOX | 900Lux |
| Period required for ROI | 26 months |
It is clear that the use of natural lighting in industrial buildings is a feasible, efficient investment that pays off rapidly.
