1 Key indicators of sustainability in Finland (figbc.fi) Markku Lappalainen Aalto University

2 1. E-value E –value (kWh/m2,a), energy consumption In one family house < 205 kWh/m2,a Apartment building < 130 kWh/m2,a School, office < 170 kWh/m2,a Hospital < 450 kWh/m2,a A Sustainable Building Design, Lecture 1: Introduction

3 Fuel factors in E- value Fossile fuels 1,0 x Distant heating 0,7 x Electricity 1,7 x Renewable energy 0,5 x (solar panels, wood- based fuel) A Sustainable Building Design, Lecture 1: Introduction

4 Energy consumption of building envilope Walls,roof,floor,windows Conduction; U-value (1/R), conductance of different insulation materials: – mineral wool 0,045 W/mK – Wood-based boards 0,045 W/mK – Polyuretan 0,026 W/mK – Light concrete 0,10 W/mK – Wood 0,12 W/mK A Sustainable Building Design, Lecture 1: Introduction

5 Energy consumption Heating of indoor air Warm water Lighting Electrical appliances Air conditioning A Sustainable Building Design, Lecture 1: Introduction

6 2.-8 Indicators Ecological footprint (kgCO2), EN Life cycle cost € Air quality (in Finland classes: S1,S2,.S3) Maximum energy consumpion= power (kW) Annual ecological footprint (kgCO2,a) % satisfied with air quality Realized energy consumpion (kwh/m2,a) A Sustainable Building Design, Lecture 1: Introduction
