What is the policy for energy-saving, CO2 reduction,
sustainablity at Maeda Corporation?
Maeda Corporation works to be recognized as“Environmental Corporate Management #1 inconstructions.”
Architectural Designing Division
included “Corporate Assesment System for Building
Environment Efficiency (CASBEE)” (http://www.ibec.or.jp/CASBEE/english/index.htm) in
ISO14001 implementation. We are now preparing
menues for environmental treatments and technology
proposals for CASBEE evaluation. One of the mostimportant aspect is to visualize the CASBEE levels.
This helps promoting environmental technologies inearly stages of planning and designing.
In building designing, directions of buildings andplacements, insulation of external walls, shading ofopenings are important. In equipment designing, using
more efficient equipments, selecting proper heat load, andmost effective arrangements of equipments are considered
to optimize the cost-performance. We utilize the tool
called “E Qualtet” which we developped 8 years ago. “EQualtet” is the energy-saving technology proposing tool.
It combines various architectural and equipmental
technologies to propose economical yet environmentallyfriendly solutions. It utilizes accurate simulations toevaluate in terms of Life Cycle cost (LCC) for cost
concerns and Life Cycle CO2 (LCCO2) for environmentalload concerns. We also start using “E-Entry” from lastyear. This lets us to “entry” conditions through interviews
with clients. This calculates energy consumption of thebuilding and suggests some energy-saving techniques.
This is the work horse for early stage of sales. This
complies to the Japanese Energy-saving law revised in
April and Tokyo’s Environment Preservation Pact andsuggest most cost effective solutions to save energy. This
tool makes the solution and its effectiveness easy tounderstand for clients.

How do you use FlowDesigner in your daily
duties. What do you think about FlowDesigner?
We use FlowDesigner from planning stages
to renewals in many different stages. For instance,
if a client is considering to upgrade the airconditioning unit and he wants to know how thecondition will be, we utilize FlowDesigner toconvince the client. Indoor heating condition,
temperature distribution in working spaces, flow
distribution, ventillations, cooling efficiency of theoutdoor units, are some examples we use
FlowDesigner for. Recently we analyzed fumefrom trash disposal area.
Before FlowDesigner, it was given bynumbers. However, it was not easy to understandfor most non-technical clients. Their complains
were; “hard to evaluate” and “hard to understand.”Viaualization of FlowDesigner with false-color
maps and vector representations is the key to makethe convincing easier.
And it makes huge
impression on clients.
FlowDesigner has been improving as version
number grows. Actual users commented that. Most
analysis have no trouble but some complicated cases
we get thorough user supports. User support isalways timely. That makes our jobs easier.

What are you planning for energy-saving, CO2
reduction, sustainablity in daily duties?
Architecture Designing Division will keep
working on “environmentally friendly proposals” fromearly planning stages. We will make sure to consider
every possible aspect of building life to be costeffectively ecological, including CO2 emission
reduction, services and renewals. Total evaluation isimpportant. Regretably, still many people think the“environment conservation” is the equipment’sresponsibility. Good energy-saving requires all aspect ofbuilding working together. Using all energy-saving
technologies with equipments do not work out if thebuilding design is not compliant to the equipments. I
hope FlowDesigner becoming to be used more widely
specially with early planning stages. The ease of use
should let more people utilize this tool for effective
communications.

Please give us comment.
I am a part of equipment designing team, mymain job is in deveopment. FlowDesigner is aneffective tool for my presentations. I will keep
utilizing FlowDesigner to make my preseatation easirfor my clients to understand.
Environmental
concerns are necessary for buildings and most clients
have extensive knowledge. So, we need to keep
updating our knowledge.
I want people to know Meada Corporation’s
attitude towards environment. I will do my best to bea good representation of our effort.
