FINAL COURSE ASSIGNMENT
SUSTAINABLE BUILDINGS

BUILDING DESIGN
Group 2 _ SUB CS1, Spring semester 2015
CONCLUSIONS
IDP
Inclusive
: Everyone, from the owner to the operator, has something critical to
contribute to the design and everyone must be heard.
Horizontal Team
: based on a multidisciplinary team that collaborate all with
each other in a horizontal line, not in a vertical discipline.
Flexible
. It´s not a closed system, is not a formula.
Each project it´s different. The system is not pre-determined, need to be adjust to each different project and his own singularity.
Adaptable
: for each part of the process. Is not a preordained sequence of
events.
Complete
: It covers all the life-cycle of the building: the next figure shows all
the key topics that EID achieve.
IDP in our building
1) Pre-design;
2) Schematic Design;
3) Design Development;
4) Construction Documentation;
5) Bidding, Construction, and Commissioning;
6) Building Operation (startup),
7) Post Occupancy (long-term operation).
IED
The IED is a new way of achieving high-performance buildings with low energy consumption and good indoor environment that allow buildings to reach very low energy use and reduced operating costs, just with at very little extra capital cost, if any.

BENEFITS IN BUILDINGS:

Buildings are built with 40-50% low energy consumption than conventional buildings.
The financial feasibility for the IED-measures is often more than 10%.
Allows the design team to focus on the passive performance of the building
(daylighting, glazing, natural ventilation, shading, thermal mass etc.) before
focusing on the mechanical and electrical installations, cooling etc.
Improved indoor environmental quality and thermal comfort, contributing to
human health;

BENEFITS FOR THE ENVIRONMENT

Reduced off-site impacts, such as stormwater runoff, greenhouse gases or other emissions;
Reduced energy and water consumption;
Increased material reuse and recycled content;
IED in our building
We will take special care in that key topics, that will affect to reach the sustainable goals: Programming, daylight, fire, thermal indoor environment, ventilation.
The 9 steps are:

1. Selecting a multi-disciplinary design team from day one.
2. Client’s needs and demands and formulate a set of specific goals for the project.
3. Making Quality Control Plan to follow-ups throughout the project.
4. Arranging a kick-off workshop to make sure that all team members have a common understanding of the design task.
5. Facilitating close cooperation between the architect, engineers and relevant experts through the concept design phase.
6. Updating the Quality Control Plan and document the energy performance at critical points (milestones) during the design.
7. Making contracts that encourage integrated design and construction.
8. Motivating and educating construction workers and apply appropriate quality tests.
9. Making a user manual for operation and maintenance of the building.

LEED
What is LEED (Leadership in Energy & Environmental Design)?

Is a program to obtain an ecology-oriented building certification for new construction and major renovations as well as existing buildings.

LEED certified buildings save money and resources and have a positive impact on the health of occupants, while promoting renewable, clean energy.



To receive LEED certification, building projects satisfy prerequisites and earn points to achieve different levels of certification. Prerequisites and credits differ for each rating system, and we have to choose the best fit for our project.
CATEGORIES
CATEGORIES
LOCATION AND TRANSPORTATION (30 points)
-> 17 points
SUSTAINABLE SITES (7 points)
-> 2 points
WATER EFFICIENCY (22 points)
-> 10 points
ENERGY & ATMOSPHERE (66 points)
-> 38 points
MATERIALS & RESOURCES (10 points)
-> 7 points
INDOOR ENVIRONMENT (16 points)
-> 8 points
INNOVATION (6 points)
-> 3 points
REGIONAL PRIORITY (4 points)
-> 1 point
TOTAL SCORE
93 POINTS
Platinum 80 to 110 points
After implement IDP and the IED we learnt how to get a
global vision of the building
,
covering all the life-cycle
and the
specifics needs
that every single step of the process need.

We also can conclude, after have followed the LEED and have done simulations with
Velux and BE10 software, that, made a building which is
fulfilling the Danish Building
Regulation is a challenge
,
especially
if we want to
fulfill
the
demands
of the class
2020
.

The frame demands in a
new building
is
more easy
than with a
renovation

of an

existing one
.

The
softwares
makes us
understanding in “real time”
the effects that every decision has on the energy consumption of the building.

Also, thanks to all that tools we can
achieve the social and sustainable targets and goals
that we need to implement in this new building era where taking care of the environment and decrease the energy consumption is something compulsory.

DAYLIGHT ANALYSIS

Practice of provides an adequate
amount of light in an enclosed space.
DAYLIGHTING:

comfort
productivity
energy consumption

Influence on:
BR 10 demand: DF ≥ 2%
SIMULATION ROOM 1
SIMULATION ROOM 2
"
amount of daylight available
in the interior compared to the amount of daylight outside under
overcast sky conditions
"
Luminance

VELUX CONCLUSIONS
The two rooms have
good lighting performances
The
visual indoor climate
for this space can be considered
good



DF average is reached
in the worst day of the year for both rooms, so in both orientations
The rooms have a
normal level of reflection
U VALUES
U-value: "
overall heat transfer co-efficient"
In the
Building Regulation
are listed the
requirements for the U-values
for the buildings’
elements.


DF
Luminance
"measure of the
amount of light reflected
or emitted from a surface"

HOW CAN I HAVE A LEED BUILDING CERTIFICATION?
"It is not possible to do creative, progressive sustainable design without a strong, like minded, integrated design team"
