These days, sustainability is a crucial topic in the construction and

real estate sectors. Increasingly, ecological, economical, and socio-cul-

tural issues are focal points in the planning, construction, and operation

of buildings. The German Sustainable Building Council (DGNB for

“Deutsche Gesellschaft für Nachhaltiges Bauen”) is the partner you

need to harmonize these aspects. With our certification system,

we help you optimize and document the quality of your projects.

Climate change, resource scarcity, and the financial crisis –

society faces a wide range of challenges today and has to

assume responsibility for current problems, rather than pass

them on to future generations. As a result, sustainability

has become a principal of our age. Nonetheless, sustainable

development is only possible if ecological, economic, and

social goals are simultaneously and equally pursued.

Buildings are responsible for approximately 30 % of raw

material use and 40 % of energy consumption and carbon

emissions worldwide. Sustainable building aims to systema-

tically reduce these figures by focusing on future develop-

ments in these fields. At the same time, sustainable building

provides social and economic benefits. In the summer of

2007, leading experts from various fields in the construc-

tion and real estate sectors therefore founded the German

Sustainable Building Council.

The DGNB‘s constantly growing community of members

mainly pursues one goal: the consistent pursuit of sustai-

nable, and therefore economically efficient, building. We

do so by systematically sharing expertise, providing further

training for market players, and raising awareness about

the issue among the general public. Furthermore, we work

with our members to gradually further develop the interna-

tionally acknowledged DGNB certificate for environmentally

friendly, economically efficient, and user-friendly buildings.

As a non-profit and non-governmental organization, the

DGNB‘s bylaws stipulate that it serves the general good.

To practice what we believe in, we primarily focus on deve-

loping criteria to increase the future building quality in ecolo-

gical, economic, socio-cultural, and technical terms. Building

owners and investors can then not only plan, construct, and

operate their projects affordably and with little environmental

impact, but also promote the well-being of building users.

The DGNB focuses on establishing and further developing

its certification system. As a high-performance, transparent,

and user-friendly tool for the assessment and certification

of sustainable buildings, it is one of the leading systems

worldwide, mainly because of its comprehensive quality

concept, which takes equal account of economics, eco-

logy, and socio-cultural aspects and is based on a holistic

view of the building‘s entire lifecycle. It is therefore possible

to define sustainability targets during the planning phase.

The result are buildings for the future with a high quality

standard documented by the DGNB certificate in gold, silver,

or bronze. This quality label is thus valuable for the const-

ruction and real estate sectors. Outside of Germany DGNB

can be used. Due to its conformity the present and future

EU regulations it is the perfect tool to ensure a high building

quality and performance.

certification and further training.the dgnb‘s core competence.

In its relatively short history, the DGNB has already man-

aged to establish itself as a leading organization in the field

of sustainable building. One major milestone on this path

was the successful market launch of the DGNB certification

system in 2009, followed shortly thereafter by the launch of

its internationalization. For instance, more than 80 projects

in Germany and abroad received the DGNB certificate in

the first 15 months. A second factor in our success is the

Setting standards. internationally.the dgnb worldwide.

As a leading cross-industry organization, the DGNB is the

main driver for sustainable development in its sector in

Germany. The DGNB is the hub at the center of the wheel.

Internationally, the DGNB also plays an important role. As

an active member of the World Green Building Council we

played an important role in setting up the European Net-

work. The European headquarters of the World Green Build-

ing Council in London and Stuttgart supports the work of

current and emerging European Green Building Councils.

Furthermore, we are integrated as researchers in major Eu-

ropean EU projects.

The internationalization of the DGNB goes hand in hand

with the further development of the DGNB certification

system. To optimally fulfill the specific requirements of

different parts of the world, we work closely with non-profit

modular training of DGNB auditors, in which we open up new

perspectives for participants in the promising future market

of sustainable building. We have come up with a modular

concept that takes account of the individual knowledge that

participants already have, their objectives, and the dyna-

mic development of the DGNB system. In the process, we

only work with renowned, third-party educational facilities,

allowing us to offer blanket training.

and non-governmental organizations abroad. These or-

ganizations will handle and adapt the DGNB system in

their countries. An DGNB international board has also been

established to ensure our high quality standard worldwide.

This board consists of representatives of the DGNB and its

partner organizations. The Austrian Green Building Coun-

cil (ÖGNI) was the first to adapt the system and awarded

the first certificates for the Austrian version of the DGNB

system in May 2010. Bulgaria, Switzerland and Thailand

have also founded their organizations. And with the Chinese

DGNB partner, we have entered one of the most promi-

sing future markets in the world. Other organizations in

Brazil and Russia have also entered into such partnerships.

Furthermore the new DGNB international system offers the

possibility to certify buildings all over the world without a

previous process.

was organized at the beginning of 2008, that figure had

risen to 121. Within just two years, the DGNB had around

900 members. At the same time, a growing number of

„As an international firm, the ECE supports the processes of

all renowned certification systems in order to demonstrate

the quality of its own real estate with measurable criteria. We

believe that the DGNB certificate, which was developed on

the basis of national and EU-wide regulations alongside DIN

standards, is currently the best certification system for shop-

ping centers in Germany. It covers the high standards that

the ECE places upon itself for planning, development, and

operation most comprehensively.“

„Ecologically, economically, and socially responsible actions

are a sign of conscientiousness and are becoming an econo-

mic factor. It is even affecting the development of our cities

and neighborhoods. Users and investors are taking a diffe-

rent look at things and basing their rental and purchasing

decisions on sustainability criteria. Certification is therefore

becoming an important marketing instrument for developers,

especially for real estate locations that attract international

clientele.

With DGNB certification for our urban projects, we pave the

way for sustainable urban and land-use development even

before actual construction has begun. We thereby provide

our customers – investors and project developers – with an

optimal starting point to flesh out the concept.“

„For REWE, sustainability in practice is especially important, as

are construction and building operations with little environ-

mental impact. With DGNB certification, we can also convince

investors in the retail real estate sector of this necessity. After

all, sustainable building will only become the norm over the

long term if providers and users of real estate are willing to in-

vest in innovation and the environment. The economic success

of our pilot market in Berlin and the great amount of attention

we have received with certification in industry, politics, and

society at large convince us that we are on the right path.“

„In less than two years, the DGNB certificate has become the

label for sustainable building in the German-speaking world.

The DGNB certificate is not only indispensable for the plan-

ning process. It is also attractive for investors, mainly because

it clearly reflects a building‘s overall quality – including its

economic performance. With the DGNB certificate, we can

offer our tenants proof of security going far beyond the clas-

sic features of „green buildings.“ Demonstration of sustain-

ability over the entire lifecycle, which the DGNB certificate

documents, will increasingly play an important role in tenants‘

decisions. We aim to use this marketing advantage, especially

in our investments in Germany.“

thE dgnb cErtificatE –your SyStEm for SuStainablE quality

The DGNB certificate is indispensable for everyone who plans sustainable

buildings and wishes to document their quality. The high-performance

system includes all relevant topics in the planning and assessment process

based on the knowledge of the DGNB‘s members. Thanks to its flexibility,

it is continually being further developed, with new occupancy profiles added

all the time. In this process, experts from different sectors work together

across disciplines to ensure the quality and wide scope of the system.

The construction and real estate sectors are subject to con-

stant change. In developing the DGNB certificate, we there-

fore made flexibility and practical application the highest

priorities. These two factors not only allow the system to

be adapted to different building types, but also smoothly

adjusted to accommodate future technical and societal con-

ditions. Furthermore, conditions pertaining to the climate,

construction, the law, and culture in other countries can

also be taken into account. As a result, projects around the

world can be certified on the same basis. That is the most

important factor in the successful internationalization of the

DGNB and its certification system.

Ensuring quality.broad expertise and clear processes.

In the ongoing further development of the DGNB certificate,

the DGNB places great store on practicability, transparency,

and a constantly high quality level. To this end, we pursue

a process in which every new occupancy profile in the

system undergoes various development phases (preparation,

pilot, evaluation, and comments) to get the broad expertise

of DGNB members and passes through DGNB committees

to ensure the high DGNB quality. On the basis of this broad

expertise, each occupancy profile is further optimized

incrementally to consistently ensure its quality. At the end

of the process, the new occupancy profile is launched on

the market.

The DGNB certificate is a tool developed from practice for

the straightforward assessment and planning of sustainable

buildings. One of its strengths is that it covers all essential

aspects of sustainable building. These aspects were defined

with broad consensus covering six fields: ecology, economics,

sociocultural and functional aspects, technology, processes,

and site. Each field contains special criteria that can be de-

signed and weighted differently depending on the occupancy

profile; each field is also viewed over the building‘s entire life-

cycle. If the building fulfills the criteria, it receives the DGNB

certificate in gold, silver, or bronze depending on the total

performance index. Building owners and investors can then

clearly document the high quality of their real estate.

Sustainable planning.with the dgnb pre-certificate.

The sooner DGNB criteria are incorporated in the planning

phase, the better. The DGNB certificate therefore covers the

building‘s entire lifecycle; with precertification, the sustain-

ability of real estate can be optimized from the outset. This

approach offers a number of benefits in planning, construc-

tion, and marketing. The early definition of all essential

sustainability criteria sets clear targets for everyone involv-

ed, which increases transparency, strengthens risk manage-

ment, and provides a safe basis for the planned performance

targets. The same holds true for financing. And of course,

the quality label also makes rentals and sales more success-

ful. For you, that means greater financial security at an

earlier stage.

Risk minimization

The DGNB certificate promotes integral building planning,

thereby capping optimization potential for construction,

operation, and the end-of-life phase. As a result, the risk of

not rented buildings is also reduced.

Greater market attractiveness

The award increases the chance of selling and renting since it

demonstrates a building’s holistic high quality to owners and

users. Furthermore, the DGNB certificate promotes greater

Focus on performance, not individual actions

The DGNB certificate assesses the building‘s overall perfor-

mance, not individual actions. Building owners and plan-

ners therefore have the greatest possible leeway in reaching

those targets. Innovative solutions are promoted.

International focus

The certification system can be updated thanks to its fle-

xibility. It can be easily adapted to new technical, societal,

or international developments.

Efficient optimization tool for planning

Along with precertification, the DGNB criteria can be used

to identify efficient, inexpensive steps during the planning

phase. Furthermore, the DGNB pre-certificate gives inves-

tors the confidence during the early planning stage that the

building‘s performance targets will be reached when it is

finished.

Risk minimization

The DGNB certificate promotes integral building planning,

thereby capping optimization potential for construction,

operation, and the end-of-life phase. As a result, the risk of

not rented buildings is also reduced.

Greater market attractiveness

The award increases the chance of selling and renting since it

demonstrates a building’s holistic high quality to owners and

users. Furthermore, the DGNB certificate promotes greater

quality and workmanship, reduces sick days, increases user-

friendliness, and improves re-rental ratios.

„It‘s good that architects are increasingly viewing sustainable

building as an opportunity rather than an obligation. This

new perspective represents a major opportunity for building

culture. We are living in an age in which the call for sustain-

ability, and especially for lower resource consumption, can

revolutionize material aesthetics, building services, and con-

struction technologies – just like the invention of reinforced

concrete did more than 100 years ago when it enabled mo-

dernity. Today, architects have to invent the architecture of

the post-fossil era. The foreseeable material revolution will

go hand-in-hand with new social demands for the usability

of our buildings and urban areas. Sustainable building once

again needs architects that think and design holistically –

a giant opportunity for our profession after decades of think-

ing in disciplines.“

„In 2007, HafenCity Hamburg GmbH began using the sus-

tainable building label in HafenCity Hamburg as an incentive

for project developers, investors, and users to become in-

volved in Europe‘s largest investment development project for

sustainable building.

Our goal was to enable sustainable urban development in all

major spheres – from urban construction to mobility, ener-

gy generation, and buildings. It was therefore natural for us

to be among the founding members of the DGNB and help

establish sustainable building throughout Germany.“

„The realization that architecture plays a major role in pro-

tecting our natural resources has brought about an important

change. Now, the goal is to harmonize people with space and

the environment. As planners, we have to develop buildings

that adapt to changing societal trends and will not be a bur-

den on future generations. We will only succeed if these buil-

dings fulfill people‘s basic needs and also have cultural value.

Architecture will then be defined by the quality of its content,

not by its stylistic appearance. This approach will bring about

a new trend in architecture that will have a positive impact on

all aspects of building.“

Heinz MornhinwegExecutive DirectorKSP Jürgen Engel Architekten GmbH

„Sustainability is not only an issue for our social responsibility

as architects; for us, it equally entails social, societal, and eco-

nomic aspects as well as questions of who should be involved

in urban development. Furthermore, flexible concepts are a

requirement for the long service life of completed construc-

tion projects. Our competence and more than 15 years of

experience in the field of sustainable planning is reflected in

recognized certifications and a number of awards.“

precise adjustments.the weighting of criteria.

To make the DGNB certificate as informative and precise as

possible, we have clearly defined targets values for all crite-

ria. Each criterion can receive a maximum of 10 points based

on its documented or calculated quality. At the same time,

it is possible to increase the weighting of each criterion as

much as threefold or to disregard it entirely based on its so-

cietal or political relevance and its importance for the specific

use profile (see the assessment matrix on page 23).

gold, silver, or bronze.performance-based scoring.

The points granted by the auditor, planner, or architect for

each individual criterion and the weighting of the criteria

collectively produce the score for the overall building and the

six topical categories. The score shows the extent to which

the requirements are fulfilled. If the score is 50 percent, for

instance, the building will receive a bronze certificate. The

score can also be based on grades, with 3.0 being required

for bronze. If the score is 65 percent, a silver certificate is

granted. A gold certificate requires a score of 80 percent.

The goal is to promote a standard of high quality for build-

ings. The performance in each of the topical categories rel-

evant for the score therefore has to be of a certain minimum

level for a certificate to be issued. For instance, gold requires

a score of at least 65 percent in the first five topical catego-

ries. Silver requires a score of at least 50 percent; bronze,

35 percent.

precise adjustments.the weighting of criteria.

To make the DGNB certificate as informative and precise as

possible, we have clearly defined targets values for all crite-

ria. Each criterion can receive a maximum of 10 points based

on its documented or calculated quality. At the same time,

it is possible to increase the weighting of each criterion as

much as threefold or to disregard it entirely based on its so-

cietal or political relevance and its importance for the specific

use profile (see the assessment matrix on page 23).

Consistent quality through the consideration of Total Performance as well as Nominal Performance Indices across all areas of evaluation

gold, silver, or bronze.performance-based scoring.

The points granted by the auditor, planner, or architect for

each individual criterion and the weighting of the criteria

collectively produce the score for the overall building and the

six topical categories. The score shows the extent to which

the requirements are fulfilled. If the score is 50 percent, for

instance, the building will receive a bronze certificate. The

score can also be based on grades, with 3.0 being required

for bronze. If the score is 65 percent, a silver certificate is

granted. A gold certificate requires a score of 80 percent.

The goal is to promote a standard of high quality for build-

ings. The performance in each of the topical categories rel-

evant for the score therefore has to be of a certain minimum

level for a certificate to be issued. For instance, gold requires

a score of at least 65 percent in the first five topical catego-

ries. Silver requires a score of at least 50 percent; bronze,

35 percent.

Dr.-Ing. Wolfram TriniusIngenieurbüro Trinius GmbH

„I was an auditor back when sustainable building was just get-

ting going, and I have already helped get a number of projects

certified. Since the beginning of the first pilot phase, I have

witnessed great interest in the possibility of having a building‘s

overall performance assessed. Contact with foreign business

partners shows that, in North America and the Anglo-Saxon

world, a sustainability certificate is part of an investor project

like a registration plate for a car. In industrial construction and

logistics, where every palette space is valuable, a sustainability

certificate for a building‘s entire lifecycle has commercial val-

ue by making different buildings comparable and by lowering

utility costs for the long-term, which represents clear addition-

al benefits for tenants and investors.“

„With training, auditors get qualifications far beyond certifi-

cations. They get comprehensive knowledge about sustain-

able building. Whether we are talking about development,

financing, planning, construction, or operation, sustainability

will be one of the main drivers in a building‘s lifecycle.“

„Sustainable building is becoming standard practice on the

German market – a clear sign that excellent building quality is a

good selling point even in times of crisis. I mainly have two hopes.

First, I‘d like for the trend to continue so that the sustain-

ability of buildings comes to represent greater quality on the

market. That would be an important incentive to successively

improve our buildings and our built environments. Second,

I‘d like for the construction sector to play its crucial role in

European and global targets for environmental and climate

policy. Through innovative, sustainable building, the construc-

tion sector can have a greater impact in the development and

implementation of future-proof solutions.“

Engineer (FH) Cornelia Jacobseningenieurbüro hausladen gmbh

„Integral planning focuses on energy efficiency, affordability,

and comfort. The DGNB certificate broadens that scope to

include other important aspects, such as the materials used

and the quality of the site. The wonderful thing about my role

as an auditor is that, on the one hand, I can document that

quality for the building owner. On the other, I also see myself

as a consultant who develops an optimal building concept in

collaboration with the entire planning team.“

and comfort. The DGNB certificate broadens that scope to

include other important aspects, such as the materials used

and the quality of the site. The wonderful thing about my role

as an auditor is that, on the one hand, I can document that

quality for the building owner. On the other, I also see myself

as a consultant who develops an optimal building concept in

collaboration with the entire planning team.“

grEat variEty on a Joint baSiS –crEating nEw occupancy profilES.

The DGNB certification system is quickly being expanded. To this end,

we have defined a transparent system development process to create

new occupancy profiles and variants as need be. The major strengths

of the process are its practicability and the inclusion of the bundled

expertise of the DGNB and its members.

Each of the system‘s new occupancy profiles goes through

different development phases. First, DGNB members (and

possibly third-party experts) come together to form a prepa-

ratory group. Without any deadline or other administrative

obligations, they set the foundations for the develop-

ment of a potential new occupancy profile for the DGNB

system. The results of the preparatory group then are passed

on to the various bodies within the DGNB. First, the DGNB

office checks whether the requirements for a new occu-

pancy profile are fulfilled. If so, the profile is passed on

to the certification system committee, which determines

whether the profile is a new, overriding type of occupancy

(main group) or a variation of an existing type of occupancy

(subcategory). In the first case, the DGNB Board of Directors

has to give its consent. Then, a working group is founded

to begin the actual development of the criteria of the new

occupancy profile. Each working group generally consists of

some 20 interdisciplinary, voluntary DGNB members who

have the explicit expert knowledge. Bundling the expertise

of architects, planners, researchers, and other representa-

tives of the real estate sector is one of the system‘s great

strengths. The experts partly try to see which criteria can

be taken over from the core system and where new criteria

need to be developed. In this way, they can incrementally

formulate a new occupancy profile, which will then be

presented to the DGNB certification system committee for

adoption.

This committee is the DGNB‘s central decision-making body

concerning the certification system. It ensures that the focal

points and targets of the DGNB certification system conform

to each other. In this task, it receives support from the

DGNB’s expert groups, each of which consists of some

10 proven experts, who ensure the quality of the DGNB cer-

tificate across occupancy profiles. They are also responsible

for the further development of the core system.

Once a new occupancy profile has been adopted, the pilot

phase begins. Here, the profile is tested on specific projects

to make sure it is practicable. At the same time, the auditors

involved are asked about their experience in applying the

profile. This evaluation process provides important informa-

tion to the working group, which optimizes the targets and

reference values used to determine a building‘s performance;

the working group also uses the information to minimize the

processing time for individual criteria. Once the feasibility of

the new occupancy profile has been demonstrated in the

pilot phase, the DGNB uses the expertise of its members for

further optimization. All members have eight weeks to pro-

vide comments and suggestions on all of the content and

results via a special online tool on our website.

„We sustainably develop with concepts adapted intelli-

gently to local conditions and the climate in order to take

advantage of specific local energy potential, which is al-

ways different because there is no single solution for eve-

ry situation. For us, sustainable architecture thus comes

about where such structural features as the site, function,

design, material, and the manufacturing process not only

cover and complement each other, but also merge to

create an overall composition of space, form, proportion,

and meaningful content.“

dynamic development.an overview of occupancy profiles.

The DGNB certification system is constantly being expanded.

Systems are already available for occupancy profiles in high

demand, such as office and administrative buildings, education-

al facilities, retail buildings, industrial buildings, and residential

buildings. While the focus has been mainly on new buildings,

the DGNB is incrementally laying the foundations for certifi-

cation of existing buildings. The DGNB working groups are

also currently working up a number of additional occupancy

profiles.

New retail buildings: consumer market

This occupancy profile includes supermarkets and retail chains.

The overall performance of the building and its annexes is in-

cluded in the assessment. The assessment focuses on energy

consumption and utilities because of the high level of such

consumption in retail buildings. The aspect of family friend-

liness was also integrated.

New retail buildings: shopping centers

Shopping centers are defined as centrally planned, large-sur-

face facilities with a concentration of retailers, restaurants,

and service firms. In assessing shopping centers, the focus

is primarily on media supply lines and retail areas, including

annexes. Changes made by individual tenants are only tak-

en into account to a limited extent, however. Furthermore,

energy consumption and family friendliness play a crucial

role in this occupancy profile.

New industrial buildings: logistics buildings

Logistics buildings are used for the distribution, delivery, and

sale of goods. The service life of logistics buildings is shorter

than that of other use profiles at 20 years. Furthermore, the

location plays a greater role in this occupancy profile. Accessi-

bility for people and goods is also an important aspect in the

assessment.

New industrial buildings: production sites

This occupancy profile covers all buildings where goods and

commodities are made from raw materials or precursor pro-

ducts with the input of labor and energy. A short service life

of 20 years is also used to assess such buildings. An impor-

tant feature of the DGNB assessment of production sites is

the separate assessment of labor/production areas and of-

fices.

New educational buildings

In the occupancy profile for educational buildings, the DGNB

provides another crucial variant of its certification system for

kindergartens, schools, adult educational facilities, universi-

ties, and rooms mainly used for seminars, lectures, and as

classrooms. The modular assessment also allows for the ad-

jacent use of offices, kitchens, cafeterias, libraries, and sports

facilities within the same building. In contrast, gymnasiums,

libraries, and cafeterias in separate buildings are not taken

into consideration. The design of external facilities is of great

importance for users and is therefore also assessed.

„The growing interest in sustainable building and such

certificates mainly shows that the focus in real estate will

increasingly be on quality and value growth. We see this

as a long-term trend that requires competent architects.

This is good news for the industry! And we see the DGNB

as an important partner that visualizes the importance of

planning in sustainable building, enables the sharing of

expertise, and performs important public relations work

and lobbying among politicians.“

„The State Capital Stuttgart has some 2,000 municipal

buildings, including schools, museums, kindergartens,

hospitals, administrative buildings, libraries, gymnasiums,

and swimming pools. These buildings have to be construc-

ted and operated affordably and with little environmental

impact in terms of materials, design, the possibility of con-

version, and expenses for energy, cleaning, and servicing.

The German Sustainable Building Council‘s (DGNB) certifi-

cation system has come up with an assessment scheme in

its certification system that also defines our demands for

sustainability and provides answers to decisive questions in

all phases of the building‘s lifecycle.“

New residential buildings

This certificate is awarded to residential buildings with,

ideally, more than six units. The focus of the assessment is on

the comfort and well-being of users. Such criteria as noise

protection, spatial flexibility, and indoor hygiene are there-

fore weighted more heavily. Likewise, low operating costs,

value retention, and the quality of the apartments them-

selves also play a crucial role in the assessment.

New office and administration buildings

This certificate is available for all buildings used mainly as

offices or for administrative purposes. Aside from ecological

and economic aspects, the focus of the assessment is on

user comfort – such as in terms of noise, temperature, and

appearance – which greatly affects the performance and

motivation of workers.

Modernized office and administration buildings

This occupancy profile was designed for existing buildings

used mainly as offices or administrative buildings with mod-

ernized façades, building services, etc. The assessment

focuses on operational costs and payback periods; in other

words, the certification system is especially suitable as an

optimization tool for architects and building owners in the

planning phase.

„What is green building? If you want to answer that

question, you quickly realize how useful a scoring sys-

tem based on professional, state-of-the-art technology

is. Certification systems like the DGNB‘s are helpful even

in the planning phase for the development of sustainable

buildings, environmentally friendly renovations, and the

tapping of ecological potential. After buildings have been

completed, certification also helps us to measure the extra

work done and assess the building‘s sustainability. Deut-

sche Bank uses a number of national and international

certifications and was a founding member of the DGNB

because we wanted to share our experience from the

renovation of the twin towers in Frankfurt, now known as

Green Towers. Our bank was the first building to receive a

pre-certificate in gold for a building that was modernized

building cultures, which increases acceptance and minimizes

the work required for an international portfolio to be certi-

compared to buildings in another. One important aspect in

the process is that the requirements for a DGNB bronze certi-

ficate are based on common building practice in the country

in question. In contrast, the DGNB gold certificate is based

on an international standard that is the same for all coun-

tries. In this way, the assessments are still meaningful on an

international scale.

The DGNB‘s approach allows its certification system to be eas-

and regulations, serves as the basis for future developments.

This approach offers a number of benefits. For instance, if a

country-specific adaptation does not include a standard for

a certain criterion, the European requirement in the core sys-

tem can be adopted. The process is similar to eco-balances.
