Ecoprofile is a method for simplistic environmental assessment of buildings and gives a good picture of the buildings resource and environmental profile. A good environmental classification can lead to a market advantage in the sale and rental of commercial buildings. Ecoprofile can also be used as an internal management and steering tool for the building owner. The Ecoprofile of a building is divided into three principal components. These components consist of the External environment, Resources and Indoor climate. The principal components are divided into sub-areas that have different consequences for the principal components and are therefore weighted. Several of the sub-areas also have underlying sub-areas. Each sub-area and underlying sub-area contains a number of parameters. There are currently 82 parameters included in the method. Each of the parameters is individually evaluated and given a grade. A description of the classes is similar to that found in NS 3424 Condition Evaluation of Structures. The grading scale is from 1 to 3 where: Class 1 = Lesser environmental impact Class 2 = Medium environmental impact Class 3 = Greater environmental impact Eventually a class 0 is going to be included that will represent a sustainable construction, but there is currently no basis for defining such a level. Currently there are levels worked out for parameters that are important for office and residential buildings.

Todays Ecoprofile is based on two earlier methods: Ecoprofile for Buildings and Environmental and Resource Effective Commercial Buildings (ERCB). The history behind these methods and their incorporation into the current Ecoprofile method are presented below. (FRSURILOH IRU %XLOGLQJV

In 1994 the Environmental Protection Department created a branch based, public steering committee for the development of a national method for environmental assessment of buildings. The method was meant to be used in the purchase and take-over of existing buildings, in connection with project engineering and renovations, additions and building of new buildings. A workshop was arranged in Oslo in June 1995 in which the framework for an environmental assessment method for buildings was discussed. The method was tested on 11 large commercial buildings in a pilot project in the fall of 1995 (Fossdal et. al., 1995). In April 1996 the steering committee delivered the report Ecoprofile for Buildings to the Environmental Protection Minister1. The report summarised their experiences in development of the method and gave recommendations for further work.1

In the course of the development work, the method has been variously called Green Appraisal, Environmental Facts, Environmental Profile and Ecoprofile for buildings.

The Environmental Protection Department evaluated the Ecoprofile for buildings concept in consultation with other affected departments. The Departments conclusions concerning Ecoprofile were summarised in a letter sent to the GRIP Centre in December 1996. The letter gives guidelines for further work, and the GRIP Centre was given among other things the responsibility for implementation of an operating organisation for Ecoprofile for buildings. In December 1997 NBI was given the job of completing Ecoprofile for commercial buildings. The projects contents were however changed in the spring of 1998 when it became relevant to combine Ecoprofile with the environmental assessment method Environmental and Resource Effective Commercial Buildings that Storebrand and Gjensidige (two Norwegian insurance companies) had developed on their own initiative.

In the spring of 1995, Storebrand and four other insurance companies took an environmental/political initiative on behalf of the insurance industry. Storebrand followed up this initiative by evaluating a possible pre-project associated with real estate management and environmental conditions. In February 1996, two meetings were held with participation of representatives from Storebrand, Norwegian Watershed and Energy works, the Building Services Dept. from Norwegian Technical University, SINTEF Energy Research Inc. And Enk Trondheim Inc2. After these meetings it was decided that a pre-project entitled Environmental and Resource Effective Commercial Buildings would be established. The goal of the pre-project was to develop a tool to map the three principal areas Energy/Power, Indoor Climate and External Environment for commercial buildings. The mapping should result in a classification of status for the three main areas, with an associated identification and prioritisation of measures to improve the condition. The pre-project report was finished in October 1996 (Viken et. al. 1996). The tool that was developed included the three principal areas Energy/Power, Indoor Climate and External Environment, with underlying sub-areas and parameters. The method was tested on four Storebrand buildings as part of the pre-project. The pre-project was transformed into a full-fledged project in January 1997 (Garli et. al. 1998). The larger project included parallel surveys to test the method on experts that hadnt been involved in the development of ERCB and to test the user manual for External Environment. The project also included a comprehensive test of the method on 14 Storebrand buildings and 10 Gjensidige buildings, followed by a thorough statistical treatment and evaluation of the results. &RPELQLQJ RI (FRSURILOH IRU %XLOGLQJV DQG (5&% The earlier Ecoprofile for buildings and ERCB have many common threads. The structure in the two methods is relatively similar, and many parameters are common. Both methods operate moreover with principal areas (components), sub-areas and parameters. The new Ecoprofile is divided into three principal components: ([WHUQDO (QYLURQPHQW 5HVRXUFHV DQG ,QGRRU &OLPDWH and includes 82 parameters. Each parameter is based on a classification scale (1,2 or 3 or larger, medium or lesser environmental impact. These form the basis for the classification of the sub-areas.2

For most of the sub-areas, the classification is just the average of the classifications of the parameters that make up the sub-area. This type of averaging implies similar weighting for all of the parameters within a sub-area. In some cases, however, matrix tables are used to define the classification of a sub-area. The sub-areas are thereafter weighted such that each principal component can be given a classification. The three principal components are not weighted. All parameters in version 1 of the new Ecoprofile are taken from ECRB or the earlier Ecoprofile. An Ecoprofile classification does not require use of measuring instruments during the on-site inspection. Interpretation of the results is best accomplished using the computer programs Enk Normtall3 and Indoor climate in office buildings (IMK)4. Enk Normtall is used to calculate recommended values for energy use in a building. Actual energy use in the building is compared with the recommended value. The IMK program is used to calculate the thermal and atmospheric climate in the building.

An environmental evaluation method such as Ecoprofile can in principal be used for three different applications: 1. To HQYLURQPHQWDOO\ FODVVLI\ EXLOGLQJV. A good environmental classification can lead to a market advantage in connection with the sale or rental of a commercial building. 2. As an LQWHUQDO PDQDJHPHQW DQG VWHHULQJ WRRO, where the building owner, through environmental classification, gets a good overview of the buildings environmental condition and what needs to be done to improve that condition. 3. As an DLG LQ SURMHFW HQJLQHHULQJ, where the goal is to create a building in a way that the requirements for best classification are achieved for each and every parameter. It is important to keep separate these three use areas in the development of Ecoprofi
