DAYLIGHTING STARATEGY FOR A MANUFACTURING UNIT

Abstract

Daylighting in a building means utilizing available sunlight by applying certain strategies

while designing a building such as placement of windows and fixtures using for windows, room

dimensions and building orientation. Effective day lighting techniques create indirect sunlight

that reduces the glare of conventional windows. Day lighting designs helps to minimize the need

of artificial lighting while also improving the general health and attitude of the occupants. With

the help of Building Information Modeling we can analyze the effect of lighting and its intensity

within the conceptual model we are using during development in all the spaces of a building and

improvise the design by making necessary changes to make it work in a more efficient way.

Background

The daylight strategy that is not typically superior to electric lighting in a building will

create a negative energy situation. Improper or insufficient day lighting results in the electric

lights being turned on which in turn increases the energy cost for the building. In the present day

situation where energy efficiency is been given the prime importance because of reasons like

natural resources becoming deficient because of the increase in population, day lighting strategy

can be considered as one of the most extremely efficient methods to reduce energy consumption

for a building. If designed in an efficient way, daylight strategy can reduce electricity for lighting

and peak electrical demand, cooling energy and peak cooling loads and maintenance cost

associated with lamp replacement and electrical service to the building. The future designs

should implement these kinds of strategies in their working process and BIM is the key tool that

can be used to understand the solar path in different seasons throughout the year after virtual

model has been designed. By such kind of approach a designer can alter their designs, which can

work in a more efficient manner utilizing all the benefits of the natural recourses on the site one

of it being day lighting to its maximum possible extent.

Case studies

1.Zausner Residence,Waldoboro, Maine.

Leed Architect: Cynthia A.Wheelock, RA,NCARB,Principal,Barba+ Wheelock

CHALLENGE:

The owner was looking for a new classic-revival style home with modern amenities that looked

like it had a sense of history and had been around for a long time. The architects, Barba +

Wheelock, wanted to maximize the use of daylighting because of the cooler northern climate and

wonderful quality of light in Maine. Additionally, the design needed to appear traditional from

the exterior. Choosing the right daylighting system for this home was a key to the design.

Daylighting exerts a profound effect on a person's mood and productivity. Poorly designed

skylights can be uncomfortable to be under. They're sometimes hot, and the glare can be too

intense if not designed properly.

SOLUTION:

This innovative Barba +Wheelock design featured “skylight dormers” which created dramatic

lighting effects and allowed daylight to bathe the rooms from above while maintaining privacy in

private areas such as bathrooms. In some areas, glass blocks set into wood surrounds enabled

rooms to glow from above and below. The skylights are on the east and west sides of the roof.

The house was designed for southwest exposure for the main living areas.

Barba + Wheelock used the Wasco CPYH – Classic Extended Pyramid Skylight.

The units are 4’-2” x 7’-9” (custom sizing) the sloped glazing was 1 1/16” I.G. – 1/4” Clear

tempered over 5/16” clear, H.S. Laminated w/Low-E (3). The light wells them- selves are 4’-2”x

7’-9” x 4’-7” (w,d,h) Some of the light wells use sloped walls to reflect the light down into the

space. While the skylights themselves are not vented, there are operable windows in the light

wells

ANALYSIS:

The key concepts to attain daylight strategies for this design include, providing large

clear glass windows and skylights for the light to enter into the space. This case study was useful

because I used the same techniques of skylights to let in more daylight into the manufacturing

unit in my design. But comparatively the scale of this residential space is much smaller to that of

manufacturing unit yet the method is similar. So, I consider this to be a successful strategy when

it comes to design and I am using Energy Analysis in BIM to verify the result.

• Architect: DesignGroup

• Civil Engineer: Burgess & Niple

• MEP Engineer: Heapy Engineering

• Landscape Architect: Kinzelman Kline Gossman

• Structural Engineer: Shelley Metz Baumann Hawk

• Ecological Consultant: Williams Creek Consulting

Project Data

• Opened: August 2009

• Building Area: 18,400 s.f.

• Construction Cost: $5.1 million

• Pursuing LEED Silver Certification.

• Energy Performance to exceed ASHRAE 90.1 standard by 56%.

• Water conserving measures will result in 48% less water usage.

• Annual energy savings expected to be $25,000.

Minimal use of interior finishes reduces environmental impact, construction costs, and

maintenance costs.

Analysis

There were several design strategies for energy efficiency used in designing this building

like the site selection, weather resistant cedar siding, store front glazing, passive solar design,

exterior shading devices, class room flex space, use of weathering steel and geothermal wells

and heat pumps. This was a helpful case study for my design because of the area of this

project is almost equal to the manufacturing unit of my design. Energy analysis of this

building has been done with the help of BIM during conceptual stages to achieve LEED

platinum rating for this building. The way in which this building has been designed to

achieve daylight strategies to offset electric usage is one thing similar to what I am focusing

to attain in my design.

Project:

I am analyzing a portion of my studio project, which is a digital manufacturing unit in a

mixed-use development space, which includes residential, retail, restaurant and office spaces.

Main focus would be on the manufacturing space, which is surrounded by office and

residential spaces. As manufacturing space requires maximum daylight considering it as a

workspace where there is different types of work carried out I and in different stages right

from receiving the raw materials and processing it a final finished product. First I have

designed my building using Revit and then an energy analysis test has been made using the

energy analysis software. The result is “FAIL” because of too much glare in the space which

would be an inconvenience for the users.So, a few changes were made in the design by which

the amount of light entering the space would be modified. And this time the designed

manufacturing space “PASSED” the energy analysis daylighting test for LEED as the

required amount of light was entering the building which is not less neither more than

required for the area. These design corrections would help me to maintain a high quality

indoor environment by minimizing the need of artificial lighting, which in turn reduce the

energy bills.

MANUFACTURING AREA: 80,000 SQ.FT

LOCATION: CHICAGO, ILLINOIS

SITE CONDITIONS: AN UNDERUTILISED INDUSTRIAL ZONE, NO TALL

BUILDINGS AROUND THE SITE

Result

The first design failed because of too much of glare. This means that more light is entering the

space than required. (Yellow portion in the energy analysis result)

Result:

The designed space passed the energy analysis test of daylighting by making changes i.e.

removing the skylights from the design, which are the prime cause for excess glare in the area.
