Business Case
As we know nowadays because of the cost energy and make a friendly environment, peoplelooking for something new. This is about consumer requesting. Constructors are also verywelcome to find a way to sell better and most profitable way to sell. So green building it s anew way to make it happens . And we are as a designer, we design green building, this will befrom first sketch up to final proposal all in all, so we can sell our design to the constructors.
I designed
Construction of a Pasig Riverside Green Building condominium in downtownManila
as 3 different ideas.

Quality Function Deployment (QFD)
Radiant cooling (Idea 1)This method will absorb the heat inside the room and transform it to radiators under thefloor for chilled floor. The process of radiant exchange has a negligible effect on airtemperature, so this technology will absorb exceeded heat so air ventilation will be mucheasier with less energy. We have 2 options as our goal to QFD for clients:Option1 : comes with 15 radiators under the floor for every 20 square meters and that
helps reduce temperature up to 12% but absolutely cheaper than option 2.
Option 2: comes with 25 radiators under the floor for each 20 square meters and reducethe temperature up to 28%.
Shading Device (Idea 2)Shading device is one of the cheapest method that we can design in a building to keepcooling inside according to VOC, it will increase occupant thermal comfort, reduce the
glare, and increase architectural design.QFD options:Option 1 : we can do the shading devices in our design.Option 2 : we can specify each unit to use shading device for better performance butundoubtedly it will be exclusive for client and a bit expensive than option 1

Energy Efficiency Window (Idea 3)Energy Efficient windows are designed to keep cold air inside and saving energy inside byeliminating the need to overcompensate for air leakage and entry during both the summer andwinter months. Also it constructed to eliminate drafts. And protecting the home against leaks,drafts, and condensation.Energy Efficient Window don t require tinting in order to perform. Tinting can reduce visible lightand obstruct views. In the same way, The sun s harmful rays can fade artwork, paper, fabric,carpet, and wood. Energy efficient coatings on glass reduce ultraviolet (UV) rays by up to 75percent.Option1 : it comes with 2 layers of glass with Arcon inside that s why this window doesn t allowedto transfer temperature.Option2 :same window with option 1 but its require to have special frame that helps us to makebig and width window for towers and apartmentsOption3 : This method can be very cheap and popular for costumers it s a thin window and reducethe ray of sun 75% and we can use it in any house by changing window.

Design 3: Energy Efficacy Window
Energy efficient window are designed to keep cold air and those types of windowsare multiple-glazed and they have low- E coatings. High quality edge spacers andframes are also common with energy efficient windows.

Design for LEED Compliance
Focus on LEED cooling and ventilation
We should show our window to engineer before installation so they will know this special window needspecial frame according to the options that we proposed so we don t have any other special task forthem.

How engineers will produce the window:
1.ConceptualizationThe project team comes together at the earliest stage, they will talk about the size,form, thickness, length, width etc. of the window and they will predict the climateand the form of the building then according to that they will make decision.
2.DesignCollaboration between the architect, contractor, and engineers allows for betterdecision making, helping to improve quality and better cooling and ventilation.
3.implementation docs.Precise virtual models are automatically part of the design, helping to reduceuncertainty in documents and chose the best design of the window.
4.ProduceBecause of careful early planning, team members are able to use best option ofthe windows according to plan, climate , budget etc. Construction can becompleted on schedule and on budget.

What I appreciate are
six sigma is customer driven
Six Sigma addresses the entire process behind the production of an item orcompletion of a service, rather than just the final outcome
What should improve:
Six sigma is base on the statics or data so many people would fail to use real life experiences orcases to improve their own business.
