Points Analysis ,[object Object],Urban Development Density SS c2 Relatively inexpensive Alternative Transport 5% Bicycle Storage & Change/Shower Room SS c4.2 * Alternative Transport Public Transportation Access SS c4.1 * Cost can be significant Brownfield Development SS c3 High credit attainment % Site Selection SS c1 * No or minimum additional cost, typical to project requirements Erosion & Sedimentation Control SS p1 Cost Implication ($) Points Description Ref.

Points Analysis ,[object Object],Minimum cost Alternative Transport Parking Capacity Reduction, Vanpools SS c4.4 * Cost depends on types of fuel etc., may become obsolete. Alternative Transport Alternative Fuel Refueling SS c4.3 Minimum cost or not achievable at all Reduced Site Disturbance Development footprint SS c5.2 * Minimum cost; Expensive if underground parking is used Reduced Disturbance Protect / Restore Open Space SS c5.1 Cost Implication ($) Points Description Ref.

Points Analysis ,[object Object],Relatively low cost for adding shade trees etc. Landscaping actions to reduce heat island effect Non-roof SS c7.1 * Swales – minimum cost impact; Retention / Detention Ponds - more expensive; Stormwater Collection Tank - costly Stormwater Management Treatment - remove TSS and TP contaminants SS c6.2 ,[object Object],[object Object],[object Object],[object Object],Stormwater Management no net increase in Rate & Quantity of Stormwater run off SS c6.1 Cost Implication ($) Points Description Ref.

Points Analysis ,[object Object],Energy Star compliant roofing – relatively inexpensive Green roof – can be costly Landscaping actions to reduce heat island effect, Roof SS c7.2 * Some premium cost – external lighting, added cost for sensor or light shades Light Pollution Reduction by eliminating light trespass from site SS c8 * Cost Implication ($) Points Description Ref.

Points Analysis ,[object Object],Low flow or waterless sanitary fixtures – premium cost Innovative Wastewater Technology WE c2 Waterless sanitary fixtures & reclaimed water system, either on site or through local water district 30% Water Use Reduction WE c3.2 * Sensors to plumbing fixture – premium cost 20% Water Use Reduction WE c3.1 * Use reclaimed water supplied by local water district – low cost Water Efficient Landscaping, no irrigation WE c1.2 * High efficiency irrigation and indigenous plants, minimum cost; rain water collection system can be more expensive Water Efficient Landscaping less potable use WE c1.1 * Cost Implication ($) Points Description Ref.

Points Analysis ,[object Object],No additional cost, standard practice CFC Reduction in HVAC&R EA p3 Cost varies – energy efficient lighting fixtures & HVAC equipment; efficient control system; low - E glazing; shading devices; soft cost for energy modeling Optimize Energy Performance 20 - 60% new 10 - 50% Existing Building EA c1.1-5 * Minimum Energy Performance per ASHRAE/IESNA 90.1-1999 EA p2 0.1-1.0% of total construction cost System Commissioning EA p1 Cost Implication ($) Points Description Ref.

Points Analysis ,[object Object],No additional cost, standard practice for new construction Ozone Depletion, no HCFC’s or Halons (including at Central plant) EA c4 Reasonable cost based on annual energy usage; operation cost rather than first cost Green Power, 2-year utility contract to buy energy from renewable sources EA c6 Can be costly System Measurement & Verification for accountability / optimization EA c5 Reasonable additional cost compared to system commissioning pre-requisite Additional Commissioning including during design process EA c3 * PV panel: 1KW - $8,000 - 8,500 Renewable Energy 5 - 20% of total building use EA c2.1-3 Cost Implication ($) Points Description Ref.

Points Analysis ,[object Object],Reuse, maintain 100% shell, 50% non-shell MR c1.3 May not achieve due to the high percentage, cost impact normally minimum Resource Re-use, Specify 5 -10% salvaged / refurbished, by cost. MR c3.1-2 Cost varies depending on project location and waste recycling program Construction Waste Management, Divert 50-75%, measured by weight MR c2.1-2 * For renovation projects only, might affect achieving energy use reduction Maintain 75 - 100% of Existing Structure MR c1.1-2 Reasonable cost Recyclable Collection / Storage MR p1 Cost Implication ($) Points Description Ref.

Points Analysis ,[object Object],High level of attainment on certified projects. Possible material cost premium due to limited resources. 50% of above Regional Materials were locally sourced / harvested MR c5.2 * High level of attainment on certified projects. Possible material cost premium due to limited resources. 20% total materials are Manufactured Regionally measured by cost MR c5.1 * High level of attainment on certified projects. Possible initial material cost premium. 25-50% total materials have Recycled Content post consumer/ post industrial - by cost MR c4.1-2 * Cost Implication ($) Points Description Ref.

Points Analysis ,[object Object],Cost Implication ($) Points Description Ref. More expensive than non-certified wood. 5 - 18% higher. 50% of wood-based materials to be from FSC-Certified wood MR c7 Few achieved this on certified project. Difficult to get percentage requirements Rapidly Renewable Materials - 5% of total materials measured by cost MR c6

Points Analysis ,[object Object],[object Object],Ventilation Effectiveness per ASHRAE 129-1997 EQ c2 Premium cost for sensors Carbon Dioxide Monitoring EQ c1 * Additional cost for temporary storage, replace filter, dehumidification equipment IAQ Plan During Construction EQ c3.1 * No (prohibition) or additional cost (designated smoking room), standard practice in CA Environmental Tobacco Smoke Control EQ p2 No additional cost Minimum IAQ Performance per ASHRAE 62-1999 EQ p1 Cost Implication ($) Points Description Ref.
