Translucent Vs. Transparent Daylighting

When Should You Use Transparent Daylighting and When Should You Use Translucent?

Proper daylighting design requires use of both translucent vs. transparent daylighting. Glass or other transparent glazings provide a view of the outside, making the room feel larger and bringing the outdoors in. However, glass also brings in solar heat and causes glare, making the space uncomfortable and difficult to work in.

Translucent Vs. Transparent Daylighting

Translucent Daylighting Is the Most Cost Effective

Utilizing translucent daylighting is the most efficient and effective way to provide natural daylighting. Translucent panels are far more effective at blocking heat, providing savings in energy usage. Translucent panels also scatter the light, eliminating glare and reducing the amount of both artificial light and amount of daylighting needed, reducing both operating costs and installation costs. Translucent panels are cheaper to manufacture and install than glass, providing the best cost to usage ratio.

CPI Daylighting’s translucent polycarbonate, like their UniQuad or QuadWall products, provide highly diffused light without glare or solar heat gain. Diffuse light is like light on a cloudy day; small shadows, no spotlighting, low heat and easy on the eyes.

Transparent Daylighting Provides a View

Glass on the other hand provides a view. However the tradeoff is that it also delivers glare and solar heat gain. Glass is also expensive, and to get similar U-values, the glass has to be coated, triple pane, and insulated with argon gases, all adding to the costs. The seals will eventually break down, the gases leak out, and performance drops, and either replacements are expensive and difficult, or impossible.

But, there are areas that a view is necessary. No one wants to work in a building without a window or view outside. So the key is to balance the translucent vs. transparent daylighting in the design.

Translucent Vs. Transparent Daylighting Usage

For general use, walls at eye height (6 feet – 8 feet) should have some transparent glazing, allowing for views outside. In almost all other cases translucent daylighting provides the best performance at the best price. It really depends upon the usage: gymnasiums work best with translucent daylighting, and office buildings do well with translucent daylighting, as glare and heat can drop productivity quickly.

Richmond Olympic Oval Is Awarded with IAKS/IOC All Time Award

New Oval Feature

The Richmond Olympic Oval Is Only North American Sports Facility Awarded with IAKS/IOC All Time Award

The Richmond Olympic Oval, the signature venue from the 2010 Vancouver Olympic Winter Games – and a venue that has 63,000 sq. ft. of CPI’s Quadwall® – has received the All Time Award from the International Association of Sports and Leisure Facilities (IAKS) and the International Olympic Committee (IOC) – an award reserved for landmark sports facilities from the past half-century.

I don’t think this is anything close to an (overstatement) – this building has no equal anywhere in the world. No building in Olympic history looks anything like this and will do anything like this.
John Furlong, CEO – VANOC

The All Time Award is only awarded once every 50 years, in conjunction with IAKS 50th anniversary, and will not be awarded again until 2065. The Richmond Oval is the only award winner in North America, and is only one of ten to win.

We have always been remarkably proud of the visionary work that helped make the Richmond Olympic Oval a stand out facility during the 2010 Games, a cultural treasure for the community and region in the years since, and now with this award from IAKS, one of the best sports facilities of our time.
CannonDesign Principal Ken Wiseman

The Richmond Olympic Oval is the first speed skating facility ever designed with long term use in mind. Built within a new urban revitalization project in Richmond, BC, it continues to enrich and support the community as a sports community center and international sports venue.

Olympic-Oval-Skate

Speed skating venues face significant hurdles after olympic games, their size, specific use, and cost of operations make maintaining them long term problematic.

The Richmond Oval was designed for multi-sport use and convertibility. The main space allows for both ice sports to operate with other sports or community uses simultaneously, and it can always be reverted to a speed skating oval at any time. To keep operating costs down, the building was designed for and achieved LEED Silver status, aided by the inclusion of CPI Quadwall to provide both daylighting and insulation.

DOD and LEED Certified Buildings

The Defense Department will not be allowed to use any money to certify its buildings LEED Gold or Platinum, under a law President Obama signed Dec. 31 2012

The National Defense Authorization Act also requires DoD to submit a report to Congress analyzing the cost-effectiveness of LEED certifications and the standards set by the American Society of Heating, Refrigerating and Air-Conditioning Engineers.

The law allows the Defense secretary to proceed with LEED certification if a project is cost effective and DoD proves it can make back the project cost in energy savings.

The federal government has 641 LEED-certified buildings and 3,954 in the certification process, according to the Green Building Council. Government buildings make up 27 percent of all LEED projects.

Federal agencies are working to meet a 2009 executive order to make 15 percent of their buildings “green” by the end of fiscal 2015. To be considered green, a newly constructed building must use 30 percent less energy than a typical building of the same size. Renovated buildings must use 20 percent less energy. Also, they must meet specific standards for water efficiency, recycling, indoor air quality and low-emission paints and sealants, among other things.
