The Netherlands Embassy – Amm Environmental Analysis Case
Agenda General information 3 Challenges 5 Design process 8 Green features & strategy 11 Summary 14
General Information Location: Abdoun, Amman Client: Dutch Ministry of Foreign Affairs Area: 1253 m² (including both existing and proposed areas) Architect: Rudy Uytenhaak Architects, Netherlands Program: Embassy offices, meeting and storage facilities, including the reuse of an existing single store residential villa with an addition of a "floating“ floor to the existing structure 3 3
General Information The site Average temperature
LEED Certified 2.2 silver 5 The Netherlands Embassy in Amman is an adaptive reuse project that was the first in the country to be awarded with the prestigious LEED Green Building Certification. It is considered to be a pioneering example of an interdisciplinary approach to design and construction, a key component to environmental design and engineering. 34 / 69 possible points certified at14 / 10 / 2010
Challenges are here !
What questions they asked ? Can we reduce energy consumption to current standards? How can we improve cooling, ventilation and comfort without increasing energy consumption? How can we make the best use of the existing structure, e.g : thermal mass? How can we retain the existing appearance of architecturally important buildings whilst improving energy and comfort? Can we make changes with occupants in place? Is the lifecycle CO assessment positive compared with demolition and rebuilding? 6
The challenges ! lack of natural sources in Jordan . Implementation of existing Jordanian policies related to design and construction is a challenge. Temperature increasing and lower rainfall levels Limited economic incentives exist for green building practices and applications (High investment cost) Greening Existing Buildings 8
Design process!

13 Section & zoning
Green features & strategies
Existing Building 15 Stone and concrete through out the building envelope to increase thermal mass Retaining existing small windows on ground floor Use of local materials (stone, concrete) for main structure
Existing Building 16 Existing structure reused for part of the design program High space double glazing on both floors
Shading parasol 17 Automatically controlled movable canvas shading features for 1st floor windows with manual overrides Movable “parasol” shading on the south façade to control solar heat gain
Movable shading 18 The roof and south portico, with their ‘parasol sheet’ and solar cells, act as a screen against the heat of the sun. The ‘parasol sheet’ on the eastern side can be opened up like a curtain in the afternoons once the morning sun has moved on
Movable shading 19 The roof and south portico, with their ‘parasol sheet’ and solar cells, act as a screen against the heat of the sun. The ‘parasol sheet’ on the eastern side can be opened up like a curtain in the afternoons once the morning sun has moved on
Ventilation 20 A number of ventilation holes for natural ventilation in the roof of the first floor, which also includes skylights to maximize daylight in the building “Parasol” on the roof: floating stone plates. Each plate is tilted in different directions so that there are enough spaces between them for natural ventilation
Pv panels usage 21 Photovoltaic panels providing approx. 3% of the building's lighting demand Solar collectors to provide hot water that is transferred directly to the building or stored in the thermal storage (existing pool) Original swimming pool space used as a thermal storage tank for HVAC systems
Usage of solar panels 22 If the daylight is harvested completely in offices at ground and first floors, 4.4 kW will be saved which is equal to 2.8% from the total load. When using PV panels to supply power to all building computers: 6.8 kW from grid will be saved which is equal to 4.3% from the total load. Running cost savings approximately equals to : 1,149 JD/year.
Green features 23 Fabric covering portions of the roof to reduce the building’s heat island effect Use of hard landscaping Preservation of existing trees and plants , including new soft landscaping focusing on low water consumption U-Value around 0.2W/m2k Such as : palm trees , acacia salicina
Office furniture 24 EMAS certified office furniture (The EU-Eco management and audit scheme is a management tool for companies to evaluate , report and improve their environmental performance) . Eco-friendly production materials, packing & transport . Reuse existing desk lighting .

The Summary !
29 re-using the existing building , use local materials . Adding a new & insulated floor. Make use of skylight to let daylight into the core of the building . Applying excellent external sun-screen to reduce heat adsorption and limited energy consumption. Using horizontal cavity between the existing & addition and use this colder air for ventilation. Re-using the existing heat pump . Sustainable Measures Summary : 7. Re-use the existing swimming pool by converting it to an underground thermal water storage ,which will be cooled by the heat pump at nighttime then the water will be used to cool the building at daytime . 8. Usage of solar panels to produce hot water for heating in wintertime . 9. Using PV panels on the roof , generating electric power which equal the consumption of the workstation in the building. 10. Preservation of the existing trees , including soft landscape focusing on low consumption. 11. Using sustainable office furniture, re-using existing desk lights .
