Lighting Consultancy
Creative works directly with architects to facilitate integration of efficient lighting strategies with your designs. From an early stage, our engineers are being tasked with complex balance of energy efficiency and daylight optimization. We can help you with interior lighting design and outdoor illumination.
Benefits of Daylight Optimization
Daylighting is the use of natural light for primary interior illumination. This reduces your need for artificial light within the space, thus reducing internal heat gain and energy use. Natural light is the highest-quality and most efficient light source available and the source is free.
An effective daylighting design relies heavily on proper building orientation, massing, and envelope design. A fully integrated daylighting system can enhance the visual acuity, comfort, and beauty of a space while controlling external heat gain and glare.
Not only does natural daylight help light our interior spaces, but it also supplies us with a connection to the outdoors. Providing occupants with natural light and ties to the outside has been proven in a number of cases to have a positive effect on human health and productivity.
3D Analysis Optimization
Daylight analysis simulations gives us information on quantity of light, evenness of light, penetration of usable light, potential glare issues and ideal locations for automated sensors.
To ensure these positive results, we take into consideration specific factors when creating a daylit designed space:
- Solar access and natural shading
- External shading devices
- Interior space arrangement
- Eye adaptation to light
- Materials light reflectance values
- Glazing selection according to facade
- Positioning of automated lighting controls
- Compliance with minimum illuminance levels
- Appropriate light levels for tasks performed in the space
- Virtual Reality - Rendered images through lighting simulation
- Building Management System (BMS) integration
Energy Efficient Electric Lighting
Once daylighting has been properly integrated, what is needed is efficient light fixtures together with control systems. For more information on innovative lighting technologies you can visit this section.
It is estimated that lighting accounts for 30 to 40% of electricity usage and costs in a typical building. Therefore, unneeded and uncontrolled lighting in a building not only wastes energy but also increases facility operational costs. In addition, lighting can affect other building technology systems such as the need for and costs of cooling spaces where lighting has increased space temperature. Lighting control systems provide lighting for occupants of the building as needed in an efficient manner, consistent with any applicable building and energy codes.
Street Lighting
We highlight system advantages and include information on how we maximize savings with optimal design, proper selection of lamps and power sources based on local conditions and project requirements.
A full report for technical and economic evaluation can include a broad range of studies. Among them, we can list the following:
- Lighting levels/Duration of use and electric loads to meet
- Lamps selection (Compact Fluorescent, LED Lamps, etc ...)
- Site Survey, Positioning of the poles (Height of the poles and distance between them to respect specific Luminosity Levels)
- Drawings for installation by Local Technicians
- Visual Impact through Photomontage
- System connected ON, partially or OFF-grid
If OFF-grid:
- Climate analysis: Sun availability, Wind conditions, Soil resistance
- Production of Solar PV, Wind Turbines, Hybrid system (Solar+Wind+Grid)
- PV selection to fit batteries, Optimal orientation, Solar Panel Heat Fade
- Controls and Sizing of the batteries
