8 Walls and roof of the first floor of the villa, central staircase and a small piece of the first floor are removed, and the existing concrete structure of the villa is made stronger. New official entrance: A glass box was placed between the two existing stone boxes of the existing villa, then a two storey, central hall, an elevator and a staircase leading to the new first floor. A new glazed pavilion containing new office spaces is then added above the existing structure The structure and four facades of the Parasol system is then added to the new building 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 Preliminary Design Concept Copyright 2009 A/E Business Council.

19 GREEN FEATURES & STRATEGIES ENERGY Retaining existing small windows on ground floor Automatically controlled movable canvas shading features for 1st floor windows with manual overrides Hard landscaping features materials with high SRI value Solar units on roof - PV and water heaters High spec glazing on both floors Stone and concrete through out the building envelope to increase thermal mass Mechanical indoor air management system (heating and cooling) with individual controls for thermal comfort (thermostats) Original swimming pool space used as a thermal storage tank for HVAC systems Use of energy efficient lighting and electrical equipment Copyright 2009 A/E Business Council. All Rights Reserved. slide 25

20 GREEN FEATURES & STRATEGIES WATER Target 30% reduction in water use Low flow fixtures Use of hard landscaping Considering use of low water use plants OTHER SUSTAINABLE FEATURES Reusing existing building Use of local materials (stone, concrete) for main structure Furniture selection to include items with high recycled content Limiting building footprint to the boundaries of existing structure Copyright 2009 A/E Business Council. All Rights Reserved. slide 26

21 GREEN FEATURES & STRATEGIES ELECTRICAL SYSTEMS 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.

25 THE CHALLENGE FOR EXISTING BUILDINGS 8 Challenges Facing the Green Building Industry**: 1. Lack of Integrated Design 2. Green Education 3. Resistance to Change 4. Greening Existing Buildings 5. Limited Post Occupancy Evaluation 6. Lack of Transit Oriented Development 7. Split Incentives for Owner-Tenant 8. Separate Capital and Operating Budgets ** Bilau G., 8 Challenges Facing the Green Building Industry, July/August 2008 Copyright 2009 A/E Business Council. All Rights Reserved. slide 31

26 THE CHALLENGE FOR EXISTING BUILDINGS The greenest building is still the one that s already built Justin Doak of the USGBC A 2006 study conducted by the USGBC reveals that by retrofitting existing buildings, owners could save, on average 90 cents per square foot annually in energy and other costs. Furthermore, these savings can earn back the investment in 2 to 2.5 years according to the study. Copyright 2009 A/E Business Council. All Rights Reserved. slide 32

27 THE CHALLENGE FOR EXISTING BUILDINGS 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 2 assessment positive compared with demolition and rebuilding? For multiple building owners, how do modifications change the overall CO 2 emissions of their building stock? Copyright 2009 A/E Business Council. All Rights Reserved. slide 33

28 GREEN BUILDING DESIGN IN JORDAN OPPORTUNITIES: Unique climate and microclimate conditions Limited natural resources Abundance of renewable energy resources including solar and wind energy Governmental and public sector support Private sector resources and expertise International market transformation Copyright 2009 A/E Business Council. All Rights Reserved. slide 34

29 GREEN BUILDING DESIGN IN JORDAN CHALLENGES: Research, development and funding for renewable energy sector Clear legislative framework for green building practice Spreading further green awareness to different stakeholders Dissemination of technical know-how among stakeholders Perception of green design as an add-on rather than an integrated process Green Washing of projects to reflect a more positive image Development of specialized curricula, programs and research in universities and educational institutions Copyright 2009 A/E Business Council. All Rights Reserved. slide 35

32 QUESTIONS 1. What are the constraints and opportunities presented by this project? 2. How do we address the issues of contextual integration and reuse in green design? What can we do with the existing stock of buildings (i.e. working with what we already have)? 3. What incentives can we give to developers and building owners to make their buildings more energy efficient? 4. What is the added value of greening this project from a social, economic, and environmental point of view? Copyright 2009 A/E Business Council. All Rights Reserved. slide 38

34 LESSONS LEARNED Introduce green goals and objectives as early as possible in the design process, preferably even before the A/E contract is signed for the project Include specific green requirements in RFP s and contracts Get everyone on board, particularly top decision makers to establish clarity of commitment by all stakeholders Involve experienced and confident team members and project managers who are familiar with the special requirements of environmental design if possible. Work with the design team to create realistic performance goals and targets for building systems Determine at early stages of the project if the client and building users support potential innovative changes that may affect the way they manage and use the building. KEEP IT SIMPLE AND DO IT RIGHT! Copyright 2009 A/E Business Council. All Rights Reserved. slide 40

35 LESSONS LEARNED The need to adopt an integrated approach to design where all stakeholders are involved from early stages of the project and are part of the decision making process Any future Green Building Regulation or Rating System must reflect the particular needs of the region in general and Jordan in specific with the proper legislative framework to support it. All elements of the built environment on both micro and macro levels must be considered It is not only about credit points The need to consider the entire lifecycle of a project from design to post occupancy and beyond The importance of creating baseline scenarios where necessary data must be collected and documented on a national level for various building types.
