Dressing up the lighting for traditional homes and gardens...

The techniques of lighting have greatly evolved beyond simple table lamps and chandeliers, yet many homeowners have not updated their thinking much beyond this approach.  So much of what we see in current design magazines and books are the ultra modern, ultra clean interiors.  It’s true that progressive design is a hot topic, but it’s not for everyone.  How does the owner of a more traditionally styled house make use of today’s lighting techniques?  Can new lighting techniques be applied to non cutting edge spaces to enhance the sense of warmth and comfort that these cozy interiors inspire?

The answer is a resounding…yes

The trick is to keep the lighting upgrades subtle so that the decorative light sources can remain the architectural jewelry for a home.  Chandeliers and table lamps are an important element to most all styles of residences.  They are needed to provide the ambiance for a room without necessarily providing all the necessary illumination on their own.  This applies outside of a home as well.  Adding a layer of accent lights, hidden among the plantings, allows the lanterns at the front door and by the garage to provide the illusion of providing the main light without visually over powering the landscaping.

Sometimes residential lighting design takes a backseat to wondrous commercial projects as far as eye catching design goes.  Lighting for homes needs to be more subtle than what goes into public spaces.  A restaurant or theater project can dive headfirst into the realm of fantasy design.  Patrons want to be transported to a place that is a different world than what they experience at home.  Yet, when homeowners are in their personal spaces they want to be able to have various levels of functional illumination for the mundane, but ever so important tasks, that are a part of day-to-day living.

Lighting can be a tremendous force.  It’s the one factor that makes all the other elements in design work together.  Yet it has for so long been the last thing considered and the first item cut from budget.  The result has left many homes drab, uncomfortable, and dark.  Too often the blame goes elsewhere, when improper lighting is the true culprit.  Becoming better acquainted with the components of good lighting will allow homeowners to communicate their needs more clearly with the sales staff in lighting showrooms and the contractors whom they have hired to do the installation.

Light has four specific duties.  They are to provide decorative, accent, task, and ambient illumination.  No one light source can perform all the functions of lighting required for a specific space.  Understanding what these terms mean will help homeowners make better decisions that will integrate illumination into the overall design and give them what they want.  Here is a description of these four functions that puts them into terms that can be easily understood by everyone involved:

Decorative light

Light fixtures such as chandeliers, candlestick-type wall sconces, and table lamps work best when they are used to create the sparkle for a room.  They alone cannot adequately provide usable illumination for other functions without overpowering the rest of the design aspects of the space.  I call them the supermodels of illuminations.  Their only job is to look fantastic.

For example, a dining room, illuminated only by the chandelier over the table, creates a glare-bomb situation.  As you crank up the dimmer to provide enough illumination to see your guests, the intensity of the light source causes everything to fall into secondary importance.  This one supernova of uncomfortable bright light eclipses the wall color, the art, the carpeting, and especially the people sitting at the table.

By nature, any bright light source in a room or space immediately draws people’s attention.  They won’t see all the other elements, no matter how beautiful or expertly designed.  For example, linen shades on table lamps draw too much attention to themselves when they are the only light source in a room.  Consider using a shade with an opaque liner and possible a perforated lid to help direct the illumination downwards over the base, the tabletop and across your lap for reading.  We’ll cover this in a little more detail in the section on task lighting below.

Accent light

Accent light is directed illumination that highlights objects within an environment.  Light sources such as track and recessed adjustable fixtures are used to bring attention to art, sculpture, tabletops and plantings.  Just like any of the four functions, accent light cannot be the only source of illumination in a room.  If you use only accent light, you end up with the museum effect, where the art visually takes over the room, while the guests fall into darkness.  Subconsciously, the people will feel that the art is more important than they are.

Good accent lighting thrives on subtlety.  A focused beam of light directed at an orchid or highlighting an abstract painting above a primitive chest can create a marvelous effect.  People won’t notice the light itself; they see only the object being illuminated.  The lighting effect achieves its magic through its very invisibility.

In the movies, if we can tell how a special effect has been achieved, we feel cheated.  We don’t want to know, because we want to think it’s magic.  In lighting, it should be no less the case.  We want to see the effects of light, but the method needs to remain unseen.  That subtlety is what will give the design a cohesive wholeness, allowing the architecture, the furnishings and the landscape to become the focus in a particular space, not the decorative fixtures or the bulbs glaring out from within them.

Task light 

This is illumination for performing work-related activities in the home, such as reading, cutting vegetables, and sorting laundry.  The optimal task light is located between your head and your work surface.  That’s why illumination coming from above isn’t a good source of task light, because your head casts a shadow onto your book, computer keyboard, or recipe book.

Table lamps with solid shades often do the very best job for casual reading, because they better direct the light and don’t visually overpower the room when turned up to the correct intensity for the job at hand.  Fluorescent or incandescent linear shelf lights too, are a good source of task illumination at a desk with a shelf located above the work surface or in the kitchen when mounted under the overhead cabinets.

Ambient light

Ambient light is the soft, general illumination that fills the volume of a room with a glow of light, and softens the shadows on people’s faces.  It is the most important of the four functions of light, but is often the one element that is left out of the design of a room or space.

The best ambient light comes from sources that bounce illumination off the ceiling and walls.  Such light fixtures as opaque wall sconces, torches, indirect pendants and cove lighting can provide a subtle general illumination without drawing attention to the light source.  You could call is the open-hearth effect, where the room seems to be filled with the light of a glowing fire.

Just filling a room with table lamps is not an adequate source of illumination.  The space winds up looking like a lamp shade showroom.  Let these lamps be a decorative source, creating little islands of light.  Using opaque shades and perforated metal lids, as was mentioned earlier, can turn these fixtures into more effective reading lights (task lights) if that is their main purpose.

Utilizing other sources to provide the necessary ambient light lets the decorative fixtures create the illusion of illuminating the room, without dominating the design.  This inclusion of an ambient light source works only if the ceiling is light in color.  A rich plum colored ceiling in a Victorian-style dining room or a dark wooden ceiling in a cabin retreat would make indirect light sources ineffective, because the dark surfaces absorb light instead of reflecting it.

In situations such as these the solution may be to lighten the color of the ceiling.  Yes, what I am saying here is that sometimes the answer is to alter the environment rather than change the light source.  Instead of the whole ceiling being eggplant-colored, how about painting a wide border in that color with the rest of the ceiling done in a cream color or similar hue?  A wooden ceiling could be washed with an opaque stain that gives it a more weathered look without taking away from the wood feel itself, as simple painting would do.  In both cases, using a chandelier or pendant fixture with a hidden indirect source could provide the much needed ambient light while maintaining a traditional look.

Ambient light, too, just like the other three functions, should not be used by itself.  What you end up with is the cloudy day effect, where everything is of the same value, without depth or dimension.  Ambient light alone is a flat light.  It is only one component of well-designed lighting.

Light layering, the bottom line

A lighting design is succecssful when these four functions of light are layered within a room to create a fully usable, adaptive space.  Good lighting does not draw attention to itself, but to the other design aspects of the environment.  An entryway, for example, desperately needs ambient and accent light, but may not need any task light, because no work is going to be done in the entry.  However, there may be a coat closet, which would need some task-oriented illumination.  The addition of a ceiling mounted decorative fixture helps set the tone for the rest of the house.

What we often see in various design magazines is a house lighted for entertaining only.  It is a very dramatic, glitzy look.  Every vase, painting, sculpture and ashtray glistens in its own pool of illumination.  Yet, the seating area remains in darkness.  What are these people going to do for light when they want to go through the mail, do their taxes, or put a puzzle together with their kids?

In reality, people entertain only part of the time.  The rest of the time these rooms are used to do homework, clean, and interact with other family members or guests.  This doesn’t mean that you should eliminate accent lighting.  Just don’t make it the only option.  Simply putting ambient light on one dimmer and accent lighting on another provides a whole range of illumination level settings.  Don’t forget to add a layer of task light and decorative light to the mix as well.

If once the installation is done and someone walks in and says, “Oh, you put in track lighting, it means that hte lighting system itself is the first thing seen which kind of defeats the purpose.  If they walk in and say, “You look great!” or “Is that a new painting?” then you know the lighting is successfully integrated into the overall room design and that you have done a good job.

The Shape Of Green Buildings...

I have to say it’s an exciting time to be practicing architecture. Yes the economy has put all sorts of new pressures on us and challenges in our path. But the mainstreaming of environmental considerations is delivering architects much more enlightened clients and an abundance of new products, materials and strategies that will allow us to create bold new designs.


The early years of the green architecture movement largely produced buildings that single-mindedly wrestled with the technical issues of energy and resource conservation while neglecting larger design issues. As a result sustainable architecture gained a reputation as being clunky and funky. This led the next generation of designers and builders to try to hide their efforts, often placing solar panels or water catchment systems behind screening elements.


There is now emerging a new wave of green design that is treating the unique materials, systems and strategies of sustainable building as opportunities that can generate new and exciting forms. It took architects a while to figure out that steel from the industrial revolution would allow them to break from classic proportions of masonry columns and beams, and that steel could lead to magnificent new forms.  Today we are we beginning to see new structures that embrace and express our new building blocks. Let’s look at the beauty of what is possible when we choose to celebrate rather than hide our green.


Renzo Piano’s California Accadamy of Sciences integrates photo-voltaic panels to form an energy-harvesting sunshade.






 Glenn Murcutt uses water-harvesting tanks as bold forms to compliment the pure geometries of his buildings.tank3



This stunning Vertical Park by Jorge Hernandez de la Garza intends to infuse the city with much-needed green space in the form of a modular skyscraper made up of a series of stacking units. The solar-powered structure contains sky-gardens in addition to spaces for living and working, and recycles all of its own water.






Michael Jantzen’s Sun Rays Pavilion, consists of 12 massive columns that rise out of the earth like giant crystals reaching for the sun. Appropriate, because the acutely slanted building relies on the sun’s rays alone for power.





Designed in the shape of a drop of water, the Water Building Resort intends to become the first building ever to convert air into water with the help of solar power. It’s south facing facade made of photovoltaic glass will harness solar energy, allowing light to pass through. The northern facade features a latticed design for ventilation as well as Teex Micron equipment that will convert humid air and condensation into pure drinking water.






This new school of art, design, and media at Nanyang Technological University takes advantage of advanced green room technologies to add much needed structure while preserving scarce open space.




Vicent Callebaut’s Lilypad is a true amphibian – half aquatic and half terrestrial city – able to accommodate 50,000 inhabitants and inviting the biodiversity to develop its fauna and flora around a central lagoon of soft water collecting and purifying the rain waters. This artificial lagoon is entirely immersed, ballasting the city. It enables inhabitants to live in the heart of the sub aquatic depths.

The Dream of the All-Electric House, Revisited...


Not General Electric’s home of the future, this demonstration project, scheduled for construction in 2010, envisions a home that is completely energy neutral.  An eight kilowatt solar array, grid connected and net metered, will produce all power necessary for domestic and transportation purposes, without any on site carbon emissions.  The owner, who has been working in the solar industry for over twenty years, is committed to, ‘getting off the pipe, a house without a gas meter.” The basic design strategy is to create a responsible intervention in an historic setting, acknowledging the context while at the same time embracing a contemporary vision of space and function.  It includes a structure with ample roof area for the panels and a highly efficient envelope. The space planning places open living spaces at the rear of the house directly adjacent to the garden.  These rooms employ ample, south facing glazing for maximum solar gain. On mild days, exposed concrete floors with radiant tubes convey passively collected heat to the north facing portions of the house via a small re-circulating pump.  We have specified Marvin wood windows with High-R-Tripane glazing and sprayed, Biobase, soy foam insulation for R-19 walls and an R-40 roof.  This creates a tight enclosure while also accounting for existing, historic “blind walls” and the inherent problems with air and moisture infiltration that they present. A three-story stair well, topped with operable skylights is a dramatic vertical space and creates a “heat stack,” providing all cooling necessary for the moderate San Francisco climate. The mechanical systems are based on the “all electric” concept.  In the active heating mode, a 2/3 ton, electric heat pump provides hot water for the floor system.  A second heat pump provides domestic hot water.  LED fixtures and high efficiency appliances lower the total electrical load, while a plug-in hybrid charges in off hours to balance production and consumption cycles with the net metering approach.   In an effort to embrace a holistic approach to sustainability we have included a gray water reclamation system.  It will provide irrigation for a shared, backyard vegetable garden and for drought tolerant, landscape features both at the yard and the street.  In this urban setting, this project represents an initial attempt to do more than “green” the structure, we are working at the level of lifestyle, beginning to think about transportation, food production and community as component parts of the architectural response.

Serious Paper Play...

Paper bags and cardboard boxes, butchers’ paper and newsprint hats.  Paper plates, papier mache and the versatile matchbox, boxes for packing and moving and play Visionaries like Gehry and Shigeru Ban use it for structure but, whether the blame rests with neat stacking Lego and Lincoln Logs or span-worthy Meccano, most of us don’t consider cardboard as a construction basic.

With around 85% recycled content typically found in corrugated card, the material offers sustainable credentials that many other product and building materials cannot match.  Frank Gehry’s seminal 1969 Wiggle chair, featuring 60 layers of corrugated card “Edge Board” screwed into compression, is a plain sexy investigation of how to achieve strength and sculpture through the opposite layering of corrugations.  Shigeru Ban’s equally groundbreaking use of cardboard structure in halls, office buildings and houses epitomizes economy in use and lifecycle, marrying the strength of the helically wound paper tube with simple, repeatable, affordable connection details.  As the architect says, “I don’t like waste”.

More pedestrian in form but super useful, compressed paper panel materials like Paperstone and EcoTop provide a paper-based replacement for pulp boards like MDF, utilizing the density and strength of papers en mass.

The ultimate in DIY cardboard emersion and superior acoustics has to be Mafoombey, a corrugated space both poetic and functional, designed for listening to music as part of the Finnish Habitare Fair 2005 by students Martti Kalliala and Esa Ruskeepää.  In awarding Mafoombey first prize Jasper Morrison commended the design for simply “turning the humble material of cardboard into something so wonderful”.





California Poppy Reserve March 2009

 When excavation is required, take care to preserve existing top soils, to set them aside in the order in which they were removed. Value and protect site soils during the construction process and return them to the land as close to their original place as possible when construction allows. Cover site soils with organic mulch during the construction process to a depth of at least 6 inches to prevent the intrusion of invasive species. Keep the soils cool and encourage microbial activity.


Landscape with native plants, particularly plants selected from the plant communities of the region.  When soils are protected and allowed to return to their native state, we are designing for the protection of the natural world. Healthy native soil is a sponge. It absorbs rain and slows down run-off. It stores and releases water and nutrients as plants require them. It filters, traps and ultimately breaks down urban pollutants such as oil, metal and pesticides. It also filters and purifies the air and water that percolate through it. It perpetuates life on the Earth by supplying valuable nutrients and antioxidants to plants.


Disturbed soils invite invasive plant species to thrive. Invasive plants affect water quality, species diversity and populations, reduce favorability for species reproduction, and reduce available food sources. Invasive plants accelerate soil erosion and stream sedimentation, absorb precious water sources and affect water quality.



Disturbed site

 When an exotic plant invades a soil community, it can alter the links between the plants and organisms that are above the ground and the plant parts and organisms that are below the ground.


A billion soil microbes are found in one teaspoon of soil. Perhaps of those billion soil microbes, there are 4000 different species of bacteria, fungi, nematodes and protozoa. The bacteria bind the finer soil particles together. These become micro-aggregates bound together by fungal vegetative growth. The abundant presence of these symbiotic fungi leads to substantial increases in the nutrient uptake of host plants. Because mycorrhizal fungi can have affects on both individual plants and plant communities, when an invasive plant is able to alter their dynamic, this may affect the long-term relationships of many plant species in a forest.


Exotic plants can directly alter the physical properties of the soil and the attributes of an ecosystem. Certain invasive plant species literally transform ecological communities.

Ventilated and Insulated Rain Screen Cladding (V.I.R.S.C.)...

Information Based on Euro Panels Overseas Literature.

The basic section of an external wall construction composed in accordance to the VIRSC principle consists


1: a load bearing structure

2: a layer of thermal insulation on the outside of the load bearing structure

3: a ventilated air gap / cavity

4: intermediate supporting structure to connect the load bearing structure and the architectural panel

5: an architectural panel

The ventilation (circulation of air) is created in the cavity by leaving an open joint at the bottom and the

top of the cladding. This principle must be followed consistently meaning e.g. that air in- and outlets

should also be designed below and above windows




In cold seasons the partial vapor pressure inside the heated building is higher than outside, leading to a

transport of vapor through the outside wall. This vapor could condensate in the air gap against the back

of the architectural panel but the dry air that circulates through the cavity will eliminate this moisture.



A very large portion of the solar radiation energy is dispersed before it even reaches the thermal insulation


– Depending on the color used, some radiation will be reflected.

– The temperature of the panel itself increases, which consumes another part of the incoming energy.

– At last, the air in the air gap is heated up, creating a chimney effect that conveys continuously fresh

outside air into the cavity, cooling down the whole construction.



Because the insulation is applied outside the supporting structure, this creates a continuous thermal barrier,

so that thermal bridges and their associated problems – such as surface condensation and consecutive

creation of unhealthy mould growth – are avoided.




The outside wall cladding functions as an umbrella, so the internal construction remains dry. Moisture

penetrating the cavity either runs down the back of the architectural panels or is removed by natural



Normally one tries to achieve a stable interior temperature but can not influence the exterior temperature

variations. By installing the thermal insulation material on the outside of the load bearing construction, the

biggest variation of temperature will occur inside the insulation material leaving only minor temperature

variations in the interior wall. In this way the interior structure is protected from high thermal stresses and

so the risk of cracks is reduced.



Because the architectural panel is ventilated both at the front and at the back, there is almost no differential

hydrothermal load working on it. This results in a stable panel behavior.

The supporting structure onto which the architectural panels are fixed can be made of:

– wood

– galvanized steel

– aluminum

– stainless steel
