5 Government (EU) regulations and opportunities for solar

6 nzeb: Origin and Objectives BENG: 50% Renewable Recast of the Directive 2010/31/UE of 19/05/2010 on Buildings Energy Performance (EPBD II) Article 9 - Nearly zero-energy buildings - 1 Member States shall ensure that: a) by 31-Dec-2020, all new buildings are nearly zero-energy buildings; and b) after 31-Dec-2018, new buildings occupied and owned by public authorities are nearly zero-energy buildings. Member States shall draw up national plans for increasing the number of nearly zero-energy buildings. These national plans may include targets differentiated according to the category of building.

7 BENG: Origin and Objectives Building feature houses and residential buildings Energy demand kwh/m2jr Primare fossil energy usage kwh/m2/jr Utility buildings Education building Health care buildings share renewable energy %

8 MARKET: It s time to plan and act now! 2016 Site identification Design Phase Construction Phase 6 months 18 months 20 months Delivery 2021 Evolution of regulation risk of anticipated obsolescence to be avoided Plan today the performances of tomorrow 2020 is in less than 4 years!

9 Kwh / m2 / Year Changing the Design Approach Before and Until now Improve EFFICIENCY Introduce RENEWABLES

10 Changing the Design Approach Adopting Soon! kwh of non renewable energy Target «0» kwh of renewable energy Site RENEWABLE energy POTENTIAL Building real OPTIMIZED RENEWABLE potential ENVELOPE & SYSTEMS installed

11 Tightening of the regulation for energy labels leads to urgency in existing estate Tightening regulations To satisfy the goals of the energy agreement, a mandatory for energy labels is entered for existing estate. This mandatory comes on top of the energysaving measures which are in the law environmental control. This means specific for the existing estate that these need to have at least energy label C in 2023 and at least energy label A in Energy label C 2030 Energy label A

Impact The Netherlands counts a office supply of more than 67000 buildings with a joint surface of more than 85 million m 2.

12 Impact The Netherlands counts a office supply of more than buildings with a joint surface of more than 85 million m 2. More than half of the existing offices asks for measures to achieve energy label C (requirement 2023). With energy label A (2030) as goal, 75% of the commercial estate needs to be addressed. 52% of the existing offices should take measures to achieve energy label C (goal 2023) 75% of the existing offices should take measures to achieve energy label A (goal 2030) = Requires adjustments to achieve at least energy label C Cijfers afkomstig uit de rapportage Verplicht energielabel voor Kantoren (november 2016) van Stichting Economisch Instituut voor de Bouw.

Emphasis on installation technique Of the total building-related energy usage less than 30% is impressionable by architectural measures(consisting of a part heating and a part cooling).

In most cases the installation technical measures are necessary in order to meet the stated objectives.

13 Emphasis on installation technique Of the total building-related energy usage less than 30% is impressionable by architectural measures(consisting of a part heating and a part cooling). Installation technical however the impact is much larger, the whole building-related energy usage is namely within the sphere of influence of the installation. In most cases the installation technical measures are necessary in order to meet the stated objectives. In particular, lighting and ventilation systems have the greatest impact on the improvement of the energy label Less than 30% Of the building-related energy usage is impressionable by architectural measures (heating and cooling) From a installation technical perspective, this percentage amounts 100% Lighting and ventilation have the largest impact on the energy usage Additional solar panels

14 Market driven methodologies and opportunities for solar

15 Solar opportunities in Environmental Rating Schemes Solar important driver to reach BREEAM Excellent (>70%) or higher Renewable energy 3% Energy efficiency 10% Low Nox heating 3% Solar important driver to reach LEED v4 Gold (60 points) or higher Renewable energy only sun and wind 3 points Optimize Energy Performance 18 points Green Power 2 points

16 Solar consequences on Environmental Rating Schemes If Roofs covered with photovoltaic panels: Less vegetation and local biodiversity? Rainwater management? Heat Island effect? Solaris

20 Thermal Storage Solar Panels Technology: : vacuum tube collector 325m² active solar panel Vertical installation on the south façade

21 Inter-seasonal Thermal Storage The Water Tanks: 2 tanks with litres total capacity Insulated with 10cm of rock wool + 30cm of polyurethane = 80cm of mineral wool Tanks are installed in series and vertically Various hydraulic connection points are judiciously placed at different levels of the tanks Heat excess is sold back to the district heating network (CPCU) Goal: Maximise Heat Stratification
