Impact of Humidity on Light

Some areas have almost 90% humidity through several months of the year. The humidity in the air coupled with water in the ground means that all components of a lighting system need to be addressed as a complete system to ensure proper functioning. The water/ humidity finds the weakest link in the system and creeps through to the other parts via capillary action which has an adverse impact on the functioning and life of the components.

Choice of hardware must also be informed by whether the environment is near the ocean, as the salines will then have an adverse impact on the componentry.

Creating Sustainable Lighting Solutions

Bushwick Park: project by AWA Lighting Designers

Over time, the architectural community has become increasingly invested in the realization of environmentally sustainable design, and this trend shows no sign of abating. This is a global movement. Sustainable solutions acting in a major metropolis can save building owners significantly on operational costs and cut back in vast quantities on the carbon emissions that would otherwise pervade. And, in other parts of the world, sustainable lighting solutions can make the difference between continuing one’s day, be that education, work or home tasks, or allowing darkness to swallow up needed hours of productivity. Thus, sustainability touches us all.

From low impact materials to energy efficiency, to design for reuse and recycling, there is much to be done. In this context, design connects architects with their partners and consultants, as they work toward their common goal of defining and creating structures that live up to the promise of sustainability. With architecture, technologies, materials and products all merge to create the tangible pieces of lighting design. In their collective application we see the final effects, and the success or failure of strategies and visions. How these pieces are put to use by installers and later by building occupants has tremendous importance on their visual comfort, efficiency performance, function and beauty that must be considered carefully from design inception.

Able to realize the vision of their architectural partners, lighting designers are critical members of the process. For, it is very true that one of the most efficient ways to reduce the overall carbon footprint of a structure is to amend its lighting design with smartly conceived and realized design. And, in the developing world, sustainable lighting nourishes the very essence of life. Thus, although it is just one piece of the puzzle, lighting has an outsized effect on sustainability. Understanding what is possible in this arena only serves to invigorate a practice and encourage new paradigms.

Light triggers critical physiological and psychological responses within human beings. And, since most of us spend the majority of our lives in the built environment, the level and quality of light within these buildings has real implications for our health and wellness. Luckily, today’s architect is armed with sophisticated structural options that allow for more lighting choices than at any point in architecture’s history. In today’s design world, it is no longer a question of whether to design with light in mind, but how to design with light in mind. As we become more aware of light’s implications on our physiological and psychological selves, and as technology affords a greater range of options, architects and their partners are left with an increased repertoire to draw from.  As it relates to health and wellness, the key points to consider are the quality, the quantity and the type of light being delivered within the space. 

Consider first how light comes into play in a health-oriented society. Many functions necessary for growth and well being such as breathing, sleeping, blood pressure, body temperature, appetite, moods, mental acuity, and the immune system are governed by the endocrine system, which is strongly impacted and affected by light, both natural & created by electric sources. There is also evidence suggesting that proper quantities of visually perceived light are needed for healthy functioning of the cerebral cortex, the part of the brain that controls motivation, learning, and creativity; the limbic system, the part of the brain that stores emotional impressions of the world; and the motor cortex and the brain stem, the parts of the brain that coordinate body movement and the maintenance of life.

Lighting Control Systems

A lighting control system consists of a device that controls electric lighting and devices, alone or as part of a daylight harvesting system, for a public, commercial, or residential building or property, or the theater. Lighting control systems are used for working, aesthetic, and security illumination for interior, exterior, and landscape lighting, and theater stage lighting productions. They are often part of sustainable architecture and lighting design for integrated green building energy conservation programs.

Lighting control systems, with an embedded processor or industrial computer device, usually include one or more portable or mounted keypad or touch screen console interfaces, and can include mobile phone operation. These control interfaces allow users the ability to remotely toggle (on-off) power to individual or groups of lights (and ceiling fans and other devices), operate dimmers, and pre-program space lighting levels. A major advantage of a lighting control system over conventional individual switching is the ability to control any light, group of lights, or all lights in a building from a single user interface device. Any light or device can be controlled from any location. This ability to control multiple light sources from a user device allows complex “light scenes” to be created. A room may have multiple scenes available, each one created for different activities in the room. A lighting scene can create dramatic changes in atmosphere, for a residence or the stage, by a simple button press. In landscape design, in addition to landscape lighting, fountain pumps, water spa heating, swimming pool covers, motorized gates, and outdoor fireplace ignition; can be remotely or automatically controlled.

Lighting control systems provide the ability to automatically power a device based on:

• Chronological time (time of day)

• Astronomical time (sunrise/sunset)

• Room or outdoor space occupancy (motion sensors)

• Presence of daylight (lighting costs and energy conservation,and daylight harvesting)

• Events

• Alarm conditions

• Program logic (any combination of events)

Chronological time is a specific time of day as pre-set timers use. Astronomical times includes sunrise, sunset, a specific day of the week or days in a month or year. Room occupancy might be determined with motion detectors or RFID tags, and is part of security and energy conservation programs. Artificial lighting energy use can be reduced by automatically dimming and/or switching electric lights in response to the level of daylighting, a technology known as daylight harvesting. Mobile phone operated controls can turn on a basic group of circulation—safety fixtures serving exterior—interior locations on approach, or to preheat a “water spa” in advance of returning. Events might include special fixtures for social occasions and holiday lighting, or overall brightness for cleaning. Alarm conditions can include doors opening and motion detected in a protected area, or manual “panic buttons-all lights on” for occupants sensing a possible intrusion. Program logic can tie all of the above elements together using constructs such as if-then-else statements and logical operators.

Visualisation of the Urban Algae Canopy by ecoLogicStudio

London architecture practice ecoLogicStudio’s Urban Algae Canopy, which was unveiled at the 2015 Milan Expo, is a pavilion made from an ETFE (Ethylene Tetrafluoroethylene) skin that has been adapted to grow algae inside it. It takes an existing architectural technology and readapts it to host microalgal cultures. The system works by pumping oxygen and a solution of water, algae and nutrients through the ETFE cushions. The rate of the algae’s growth inside the system will vary with the strength of the sun.

First Zero Net Energy Community In California Announced

meritagehomes-e1430160890755

First Zero Net Energy Community In California

There are several ZNE homes throughout California, but none clustered at one community. This community not only allows the value of operation cost reduction to the homeowners, but provides much-needed data to the utilities about kW production and demand at each home, and cumulatively at the transformer level to provide needed data to design service for community level Zero Energy as California building code progresses toward this standard. Meritage Homes is opening the first zero net energy community in California in Fontana, which is about 50 miles east of Los Angeles. Twenty of their Sierra Crest homes comprise the community. It is expected that 6 of the 20 will be ready by July of this year.

UN Global Efficient Lighting Forum held in Beijing

Beijing hosted a global energy-saving forum from Monday to Tuesday, bringing together governments, the private sector, financial institutions and international agencies to reaffirm their commitment to implementing a worldwide transition to energy efficient lighting.

The Global Efficient Lighting Forum was spearheaded by the United Nations Environment Program (UNEP) and inspired by the United Nations Secretary General’s Sustainable Energy for All (SE4ALL) initiative, which prioritized lighting as one of its five energy efficiency accelerators. Among the various measures, investing in efficient lighting instead of building new power plants is the cleanest, fastest and most cost-effective way to reduce climate change, the UNEP said.

UNEP estimates that replacing all inefficient on-grid lighting globally with innovative, energy-efficient alternatives would result in over 1,000 terawatt hours (TWh) of electricity savings annually, which is equivalent to the annual use of India and the United Kingdom combined. This electricity savings is equivalent to over 120 billion U.S dollars in avoided electricity bills and the reduction of over 530 million tonnes of CO2 annually.

LED lighting and digital control systems are revolutionizing lighting services by delivering improved levels of energy efficiency to all sectors. If there were a global transition to LED, it would reduce electricity consumption by 1550 TWh worldwide, which could provide 1.5 billion household with electricity. Representatives attending the forum have reached an agreement to double the global rate of energy efficiency and make sustainable energy for all a reality by 2030.

The forum was hosted by the Global Efficient Lighting Centre (GELC)-UNEP Collaborating Centre, with support from China’s National Development and Reform Commission, Industry and Information Technology Ministry, and the government of Beijing Municipality.
