2 GREEN VALUE A STUDY OF THE VALUE OF GREEN BUILDING AND SUSTAINABLE PRACTICES IN THE CZECH REPUBLIC presented by the COSTS, BENEFITS AND VALUES OF GREEN BUILDING TASK GROUP of the Czech Green Building Council Eric Johnson Executive Cost Manager, Gardiner & Theobald Cory Benson Managing Director, Made Sustainable Jíří Kubias Design Director, Optimal Engineering

3 The GREEN VALUE group was created from a multidisciplinary group of council members to prepare a professional design study specific to the Czech Republic, which would quantify the differences in the up-front cost and both short and longterm values of new green buildings relative to typical regional practices. A major hurdle for the implementation of sustainable development practices locally has been the lack of a RELIABLE AND COMPREHENSIVE ASSESSMENT OF GREEN BUILDINGS specifically addressing the Czech market. Our study aims to provide a reputable comparison of office building valuation between more sustainable green building practice and typical Czech practice, to guide developers in this interim period before more green projects are realized, and direct data can be compiled. KEY CRITERIA of the GREEN VALUE STUDY include: realistic review of typical local specific projects sample of regional-specific design solutions and modifications accurate energy savings anticipated to be achieved estimated effects of green building on operating costs expected impacts to the leasing of green office space projected resale or long-term value to be created

4 While many INTERNATIONAL STUDIES HAVE CONFIRMED THE VALUE of Green Building worldwide, our GREEN VALUE STUDY will focus on the Czech market. Sustainability and the Dynamics of Green Building - Eichholtz, Kok, and Quigley The selling prices of green buildings relative to comparable buildings nearby are higher by more than 13 percent. The Value of Green Buildings New Evidence from the United Kingdom Chegut, Eichholtz, Kok, and Quigley Results suggest a positive impact of green characteristics on sales and rental prices in the order of 8 percent and 16 to 20 percent, respectively. The Economics of Green Building - Eichholtz, Kok, and Quigley It appears that LEED registration is associated with an effective rent increase of 7.9 percent.a LEED-certified building with a normalized score of 60 (GOLD, or about one standard deviation above the average score of certified buildings) has an incremental rent almost ten times as large, 20.1 percent. Green Noise or Green Value? Measuring the Effects of Environmental Certification on Office Property Values - Fuerst and McAllister 2008 The results suggest that certified buildings have an average rental premium of 4-5%. Furthermore, based on a sample of sale prices for 559 Energy Star and 127 LEED-certified buildings, we find price premia of 26% and 25% respectively with higher levels of certification achieving higher premia. Does Green Pay Off? By Norm Miller, Jay Spivey and Andy Florance 2008 The average LEED impact on sales price per square foot is a positive 9.94% or roughly 10%.

5 The GREEN VALUE group is a VOLUNTEER TASK GROUP of the professional general members of the CZGBC working in design, project management, and consulting. The development of the GREEN VALUE STUDY is overseen by: Task Group Chairman - ERIC JOHNSON, Executive Cost Manager for Gardiner & Theobald Mr. Johnson, both a LEED and BREEAM Accredited Professional, specializes in the planning, cost management, and delivery of green commercial development projects, and brings his experience on real world, efficient control over project development to the task group to ensure its inclusiveness and professional credibility. Sustainable Strategies Vice-chairman - CORY BENSON, Director of Made Sustainable Mr. Benson, also a LEED Accredited Professional, is an Architect specializing in independent sustainability review and green building project management. He brings a design management perspective and extensive experience with construction practice and management to the group.

6 The GREEN VALUE group is made up of volunteers from a broad range of professionals practicing in the Czech design and real estate development market. Our group is comprised of ARCHITECTS, ENGINEERS, SUSTAINABILITY CONSULTANTS, QUANTITY SURVEYORS, CONTRACTORS, REAL ESTATE CONSULTANTS, CONSTRUCTION MANAGERS, and PRODUCT SUPPLIERS from many locally represented companies. Each active member company has and continues to provide assistance in their area of expertise as we develop the study, whether it is the building and system designs of the Architects & Engineers, or the cost and value estimating of the Quantity Surveyors and Real Estate Specialists. The GREEN VALUE team:

7 The GREEN VALUE STUDY was conceived of in the early stages following the founding of the CZGBC when it became clear that more needed to be done to promote the ADVANCEMENT of SUSTAINABLE BUILDING in the Czech Republic. STUDY PLANNING ARCH DESIGN MEP DESIGN COST ESTIMATES FINAL REPORTING 9/2010 5/ /2011 work began on the study in the Autumn of 2010 architectural design was completed in early Spring 2011 design engineering completed in the late Spring 2011 cost analysis to be completed late Summer 2011 final report to be compiled late Autumn 2011

8 The GREEN VALUE STUDY is a VALUATION REVIEW of three building designs. Our concept is to evaluate the ACTUAL ESTIMATED COSTS of a Green Building relative to typical local construction. Recent Czech development can often be divided into 2 categories: basic minimum code compliance and a higher standard of best practice. It is therefore the two typologies that provide the control for our study. Each design proposes a REALISTIC POTENTIAL SOLUTION that could develop independently to meet a simple Client Brief, theoretical but common in practice: CLASS A OFFICE BUILDING of 13,000 m 2 GLA, with ~2,000m 2 floor plates, 5-7 stories Site: 6,000 m 2, previously developed, BORDERING THE CITY CENTER, near public transit Provide on-site parking, opportunity for ground floor retail, and flexible open plan floor plates CODE TYP. BEST GREEN Base Code Compliant Typical Best Practice Green Building THREE INDEPENDENT design teams and design SOLUTIONS were selected to represent actual project development and to avoid the inaccuracies of individual costing or value engineering of independent design solutions or building systems.

9 To understand the ENVIRONMENTAL or GREEN character of three solutions, 57 SUSTAINABLE STRATEGIES were defined in 8 categories taking cues from some of the more popular certification systems such as LEED, BREEAM, and SB Tools. The solutions were then evaluated relative to these strategies. PRE DESIGN ex. Integrated Design, Building Geometry, & Site Location SITE IMPACT ex. Pervious Paving, Reduced Parking, & Bicycling Infrastructure DESIGN IMPACT ex. Glazing Ratio, External Shading, Landscaping,& Green Roofs ENERGY PERFORMANCE ex. Performance Targets & Building Commissioning

10 Each of the 3 separate design solutions then incorporated the SUSTAINABLE STRATEGIES to the degree which our group established as appropriate to their typology. This allowed each project to develop naturally and independently, much like a traditional office project. MATERIALS ex. Local, Low Embodied Energy, Low Maintenance, & Low VOC MEP SYSTEMS ex. Natural Ventilation, Heat Recovery, Smart BMS, & Renewables CONSTRUCTION PROCESS ex. Waste Recycling & Landfill Diversion POST OCCUPANCY ex. Occupant Education, Optimization, & Interior Flexibility

11 CODE The CODE solution is seen as the lowcost building option indicative of projects where minimizing capitol investment is t h e C l i e n t s h i g h e s t c o n c e r n. Technologies and design solutions are utilized ONLY to meet minimum code compliance, with NO or little effort to provide ADDITIONAL design or equipment EFFICIENCY. Areas; GEA: 3,380m 2 Typ. Floor; GIF: 2,850m 2 / NLA: 2,250m 2 Total; GIF: 17,320m 2 / NLA:13,325m 2

12 CODE

13 CODE Each solution provided key features improving on the base Code standard: Raised floors: 150 mm 4 pipe fan coil HVAC system Reception desk & 24 hour security Card Access security Parking: 1 space per 80m 2 Landscaped courtyard Operable windows External fixed louver sun blinds

14 TYP. BEST The BEST PRACTICE solution is seen as the typical high quality building, most often used for Class A office locally. Control of capitol investment is a concern, yet the quality of a MORE INTEGRATED DESIGN often allows design and system solutions to be developed to increase p r o j e c t q u a l i t y a n d v a l u e. INCREASINGLY EFFORTS are made TO IMPROVE building EFFICIENCY. Areas; GEA: 2,967m 2 Typ. Floor; GIF: 2,543m 2 / NLA: 2,416m 2 Total; GIF: 14,166m 2 / NLA:13,298m 2

15 TYP. BEST

16 TYP. BEST The Best Practice solution increased the quality standard and MEP system capacity and efficiency, and includes: Intelligent Lighting Control system Bike Parking in the Garage Extensive Exterior Sun-blinds Conf. Room Demand Control Ventilation Naturally Ventilated Car Parking Extra Parking: 1 space per 70m 2 Operable Windows Active Cooling Beams Air and Water-side Free Cooling Small amount of Green Roofing specification of Low VOC finishes

17 GREEN The GREEN BUILDING solution is seen a s t h e c u r r e n t t r e n d w h e r e a n INTEGRATED DESIGN, REALIZATION, AND OPERATION is used to deliver a more sustainable building, both from ENVIRONMENTAL AND ECONOMIC perspectives. These buildings include interconnected design and system solutions to IMPROVE EFFICIENCY AND VALUE and often seek independent certifications verifying their sustainability. Areas; GEA: 3,490m 2 Typ. Floor; GIF: 3,100m 2 / NLA: 2,470m 2 Total; GIF: 17,060m 2 / NLA:13,585m 2

18 GREEN

19 GREEN The Green Building solution exceeds the standard of both other projects, making building efficiency the priority, including: Activated Slab Heating & Cooling LED Lighting specified throughout Smart Building Management System Large Atrium with Passive Cooling Increased Bike Parking capacity Reduced Parking: 1 space per 100m 2 Intelligent Exterior Sun-louvers Thickened Exterior Insulation Increased amount of Green Roofing Ground-source Heat Exchange

20 A key metric to the sustainable and economic evaluation of the GREEN VALUE of each building is ENERGY CONSUMPTION and the resulting building operating costs. To ensure valid comparison our 3 engineering teams conducted a detailed ENERGY SIMULATION according to the CZECH EPBD METHODOLOGY agreeing on the common simulation inputs (all areas m 2 are GIF). Heating/Cooling set points: 20/26 C Ventilation: m 3 /occupant, depending on use group 15m 2 /occupant Internal Gains of 5.3 W/m 2 occupant, 15 W/m 2 appliances Linear Fluorescent Lighting: 7 W/m 2 Local Electric Hot Water at 2800 m 3 /year Typical 2 zones per floor CODE TYP. BEST GREEN Base Code Compliant Typical Best Practice Green Building

21 The detailed ENERGY SIMULATION according to the CZECH EPBD METHODOLOGY, undergoing final revision and coordination for each design has provided general energy consumption and annual utility costs estimates for comparison. CODE TYP. BEST GREEN Base Code Compliant Typical Best Practice Green Building kwh/m 2 ~300 kč/m 2, 12 /m kwh/m 2 ~275 kč/m 2, 12 /m 2 estimated whole building savings: ~150 MWh 346,000 kč, 13, kwh/m 2 ~230 kč/m 2, 9 /m 2 estimated whole building savings: ~450 MWh 1,039,000 kč, 41,600 These preliminary results with our three designs, confirm that most GREEN BUILDINGS OUTPERFORM typical buildings, both in energy consumption and in reduction of operational utility costs.

22 The NEXT STEPS towards the completion of the GREEN VALUE STUDY remain the detailed quantity surveying of all anticipated construction costs, the remaining estimation of additional costs and values, and the compilation of the final report. STUDY PLANNING ARCH DESIGN MEP DESIGN DETAILED COST AND VALUE ANALYIS FINAL REPORTING 9/2010 5/ /2011 These remaining steps are anticipated to be completed by the end of this coming Autumn, with the report being made PUBLICLY AVAILABLE at the END OF 2011: complete quantity surveys, estimating construction costs, for each the 3 proposed solutions outline the operational cost implications of each design solution provide a real estate (leasing and potential sale) analysis of each solution review of any perceived or real additional design and consulting fees ultimately summarize the analysis of the true cost impact of green building and certifications
