ENVIRONMENTAL PERFORMANCE INDICATORS (EPI) for the real estate and construction industry in Finland
✔ Life cycle planning ✔ Eco-efficiency ✔ Energy saving ✔ Life cycle cost ✔ Environmental impact category ✔ Environmental performance reporting
TOOLS TESTED for the purpose of developing environmental and life cycle expertise A vision shared by the Finnish construction and real estate industry is that its environmental expertise will represent the leading edge of international knowhow by 2010. To this end, a broad-based project called ”Environmental Performance Indicators for Construction Industry EPI” was launched to work out a set of indicators for the environmental and life cycle performance of buildings in order to provide a basis for a high standard of eco-efficiency for activities in the Finnish construction and real estate sector. The EPI Project was carried out by the Confederation of Finnish Construction Industries RT in collaboration with Technical Research Centre of Finland (VTT), other central organizations and companies representing the construction and real estate fields. When the indicators were defined, due consideration was given to the standards for evaluating the environmental impact of buildings and building components, official regulations, directives, international conventions and the national environmental strategy adopted by Finland.
The EPI indicators can be applied to •
manage and control building construction and maintenance from the project planning stage to final decommissioning
•
allow property owners and contractors to carry out the environmental impact calculations over the entire life cycle of the buildings
•
classify new and existing buildings according to environmental impact category based on generally accepted rules to enable service life planning of buildings
•
evaluate the inter-dependence between environmental and financial considerations more accurately and to report on the environmental impact of the activities carried out by companies.
LAURI RATIA CEO, Lohja Rudus Oy Ab Chairman of the Confederation of Finnish Construction Industries RT in 2004 ”Practical application of the environmental performance indicators calls not only for a strong commitment on the part of the whole industry but also for sound self-interest because environmental and life cycle expertise is becoming an increasingly important competitive advantage.”
The EPI indicators and tools developed in the course of the project will be tested in several real-life building projects. To make it easier to use the indicators, specific instructions have been prepared for property owners, developers, designers, contractors, the building products industry and the building engineering systems sector. The instructions give a presentation of the main stages and critical interfaces of the process, including decision-making criteria. Calculation examples are provided to show how eco-efficiency is linked to finances. The EPI indicators and tools complete with instructions are posted on the Internet portal at www.rakennusteollisuus.fi/rem.

LIFE CYCLE PLANNING ensures sustainable solutions By means of life cycle planning, it is possible to construct a building in a sustainable manner and thereby ensure that it satisfies the requirements imposed by owners, users and society throughout its life. In designing the structure, due consideration must be given to the functionality of spaces, indoor conditions, service life, adaptability, safety, easy access, environmental pressures, and life cycle costs.
EcoProP is an Excel-based tool developed by VTT Building and Transport for the planning and documentation of functionality requirements for buildings. This tool allows the user to assign requirements to three classes, the point of departure being the current regulatory framework and the highest the Eco Level.
LEVELS OF LIFE CYCLE ASSESSMENT Corporate level, building stock level Owner’s or user’s life cycle strategy, such as environmental indicators for the real estate business • Life cycle strategies, environmental values, management and decision-making systems.
Property level Life-cycle features of buildings, such as the environmental impact category • Productive, usability, health, natural resources flows, emissions and wastes, risks, etc.
Systems and structurels level Life cycle and environmental features of systems and structures • Energy economy solutions, durable materials, adaptability, etc.
Equipment and product level Environmental features of equipment and products • Material selections, manufacturing process, recycling, transportation, etc.e

Using this Internet-based tool, it is possible to evaluate the main environmental impacts of the building by means of simple and reliable indicators. By assigning scores to various environmental properties, an overall grade is obtained reflecting the standard of the building’s environmental features. The main criteria used for classification are the users’ health, natural resources flows, ecological impacts, and environmental risks.All in all, there are close to 40 individual environmental indicators.

ENVIRONMENTAL RISKS Environments risks posed by the site
By means of the PromisE Environmental Classification System, buyers or lessees can evaluate the ”environmentally friendly” of the building very much the same way as the energy performance of household appliances. The top grade ”A” requires an extremely high standard of quality. Only a couple of per cent of all buildings in Finland achieve this level. An estimated 10% of Finnish properties may qualify for the second highest grade ”B”. The lowest level ”E” is equivalent to the standard required under current building regulations. The PromisE Environmental Classification System is a tool for marketing and property improvement. Using this system, the property owner can evaluate the environmental performance and eco-efficiency of his building stock, set ambitious goals for reducing environmental impact and to instruct the staff in the environmental impact exerted by buildings and ways of reducing it. Environmental classification can be applied at any stage of construction from project planning onwards, making it possible to use it as a design and planning control tool. The Internet-based PromisE tool is available at www.promiseweb.net.

Environmental product declarations for building products In 2003 the EU Commission initiated the preparation of harmonized CEN standards concerning the environmental product declarations for building products and the environmental impact of buildings. Voluntary procedures have already been put in place in several countries based on the ISO 14000 series standards, etc. Environmental product declarations and building life-cycle assessments (LCA) have been made in Finland for about 5 years. For building materials and products, RT environmental declarations will be available before the harmonized international standards are adopted. To some extent, they are also applicable to building services equipment.
For more details, see www.rts.fi.
The environmental product declaration of a building product lists its environmental impacts, such as energy consumption, raw material consumption, emissions into the atmosphere, and use of natural resources. The declarations also address the main environmental aspects, such as health risks and recycling considerations when the construction work is in progress, the structure is in service and when it is demolished. The environmental product declarations make no judgement about the service life of the products or place them in any ranking order in terms of environmental impact. Instead, the environmental declarations seek to promote the use of building products that have less impact on the environment than equivalent products. Environmental product declarations and public databases are used to calculate the environmental profiles of individual structures and these results are then applied to work out the life cycle assessment for the entire building. Service conditions and energy consumption are included in the calculations at this point.

Senate Properties has carried out a number of pilot projects as part of the EPI programme. One of the tasks was to complete the LCC and LCA calculations for the Medi Project of the University of Kuopio pictured here.
Service life planning means looking ahead Service life planning ensures that the structures retain the required performance characteristics throughout their foreseen service life. The LifePlan Project carried out by VTT in collaboration with construction companies and organizations produced an extensive service life and life cycle file for building products. Using this file, the client can now select structures and materials based also on as maintenance requirements and costs.
Guide for calculating building heating requirements The Building Energy Calculations Project launched by the Confederation of Finnish Construction Industries RT was carried out to develop a method for computing the heating capacity required by various spaces. The calculation is based on zoning with due regard to heat losses, preferred indoor temperatures, internal thermal energies and the rates at which they can be used.
Calculation of the energy efficiency of building services systems The Project for Calculation of Energy Efficiency of Buildings and Related Indicators coordinated by the Finnish Development Centre for Building Services Ltd (TAKE) is developing methods for calculating energy efficiencies from the standpoint of building engineering systems.
Instructions and software for computing life cycle costs The life cycle costs of a building consist of construction, maintenance, modifications and repairs, and demolition. A calculation guide for LCCs complete with examples was prepared as part of the Environmental Performance Indicators Project. Additionally, a survey of existing LCC software was carried out. The purpose of LCC methods is to support investors to compare the efficiency of investment alternatives.
ENVIRONMENTAL REPORTING – instructions and indicators A guide was prepared in connection with the EPI Project providing guidelines for voluntary reporting on environmental performance by real estate and construction companies and organizations. Typical issues to be addressed in the reports include • environmental policy and management system • environmental impact exerted by the activity (raw material and energy flows, emissions, recycling, wastes, land use) • environmental risks • corrective action taken • measures to ensure eco-efficiency in the operation and maintenance of properties (owners, users) • measures to ensure eco-efficiency in the construction supply chain • other environmental responsibilities. The environmental report can be presented as a separate report or as part of a broader corporate citizenship report. The environmental report can be in a hardcopy or electronic format. The indicators developed in the course of the EPI Project can be used to monitor the company’s eco-efficiency. The indicators are subdivided into three main categories: Internal efficiency and expertise • Environmental management • Environmental impact of own activities • Environmental training • Expertise in methods to improve management of environmental impacts. Customers, stakeholder groups and eco-networking • Environmental reporting • Environment-classified products • Requirements imposed on service providers Profitability management • Environmental investments • R&D investments in improving environmental performance
