4.3.2 Other rooms.

4.3.2.1 - Facilities with preschools shall comply with Rules Regulating Child Care Centers (Less Than 24-Hour Care) 12 CCR 2509-8 and shall comply with the Colorado Department of Public Health and Safety's Regulations Governing Child Care, 6 CCR 1010-7.

4.3.2.2 - Special education classrooms. Special Education classrooms and facilities meeting or exceeding the accessibility and adaptive needs of the current and reasonably anticipated student population, in accordance with Section 504 and Title II of the Americans with Disabilities Act, the Exceptional Children's Educational Act, and Individuals with Disabilities Education Act.

4.4 Building performance standards and guidelines for green building and energy efficiency.

Section 24-30-1305.5 C.R.S., requires all new facilities, additions, and renovation projects funded with 25% or more of state funds to conform with the High Performance Certification Program (HPCP) policy adopted by the Office of the State Architect (OSA) if:

* The new facility, addition, or renovation project contains 5,000 or more building square feet; and

* The project includes an HVAC system; and

* If increased initial cost resulting from HPCP can be recouped by decreased operational costs within 15 years, and

* In the case of a renovation project, the cost of the renovation exceeds 25% of the current value of the property.

4.4.1 High Performance Certification Programs.

4.4.1.1 The Department of Personnel and Administration, Office of the State Architect has determined the following three guidelines as meeting the High Performance Certification Program (HPCP) requirements per C.R.S. 24-30-1305.5; the U.S. Green Building Council, Leadership in Energy and Environmental Design - New Construction (USGBC LEED[TM]-NC) guideline with Gold as the targeted certification level; and the Green Building Initiative (GBI), Green Globes guideline with Three Globes the targeted certification level; and for the Colorado Department of Education, K-12 construction, the Collaborative for High Performance Schools (US-CHPS) is an optional guideline with Verified Leader as the targeted certification level.

4.4.1.2 - LEED, or Leadership in Energy and Environmental Design (for schools) is a globally recognized symbol of excellence in green building.

4.4.1.2.1 LEED is an internationally recognized certification system that measures a building using several metrics, including: energy savings, water efficiency, sustainable land use, improved air quality, and stewardship of natural resources.

4.4.1.2.2 Points are awarded on a 100-point scale, and credits are weighted to reflect their potential environmental impacts. Different levels of certification are granted based on the total number of earned points. The four progressive levels of certification from lowest to highest are: certified, silver, gold and platinum.

4.4.1.3 United States Collaborative for High Performance Schools (US-CHPS). US-CHPS reflects the three priority outcomes of the Core Criteria. These are, in order of importance.

4.4.1.3.1 Maximize the health and performance of students and staff.

4.4.1.3.2 Conserve energy, water and other resources in order to save precious operating dollars.

4.4.1.3.3 Minimize material waste, pollution and environmental degradation created by a school.

4.4.1.3.4 The CHPS National Technical Committee has weighted the available point totals for prerequisites and credits in seven categories to reflect these three priorities.

4.4.2 Renewable energy strategies.

4.4.2.1 - Solar Photovoltaic / Solar Thermal.

4.4.2.1.1 SB 20-124 Requires consultation with the incumbent electric utility regarding energy efficiency; beneficial electrification, as defined in section 40-3.2-106(6)(a); and renewable distributed generation opportunities.

4.4.2.2 - Geothermal / Geo exchange.

4.4.2.3 - Wind.

4.4.2.4 - Passive Solar Design.

4.4.3 Energy management plan.

4.4.3.1 - Energy programs assist with creating a culture of energy efficiency within a school. Reference Energy Star Guidelines for Energy Management to help develop a plan.

4.4.4 Other energy efficient options.

4.4.4.1 - ENERGY STAR Labeled HVAC / mechanical systems.

4.4.4.2 - Windows, doors, and skylights (collectively known as fenestration).

4.4.4.3 - Building Envelope.

4.4.4.3.1 - The interface between the interior of the building and the outdoor environment, including the walls, roof, and foundation - serves as a thermal barrier and plays an important role in determining the amount of energy necessary to maintain a comfortable indoor environment relative to the outside environment.

4.4.4.3.2 - Roof. Roof design and materials can reduce the amount of air conditioning required in hot climates by increasing the amount of solar heat that is reflected, rather than absorbed, by the roof. For example, roofs that qualify for ENERGY STAR® are estimated to reduce the demand for peak cooling by 10 to 15 percent.

4.4.4.3.3 - Insulation is important throughout the building envelope.

4.4.4.4 - Lighting.

4.4.4.4.1 - Light emitting diodes (LEDs), compact fluorescents (CFLs) and fluorescent lighting should be considered over traditional incandescent lighting.

4.4.4.4.5 - Commissioning, retro commissioning and re-commissioning.

4.4.4.4.5.1 - Commissioning ensures that a new building operates initially as the owner intended and that building staff are prepared to operate and maintain its systems and equipment.

4.4.4.4.5.2 - Retro commissioning is the application of the commissioning process to existing buildings.

4.4.4.4.5.3 - Re-commissioning is another type of commissioning that occurs when a building that has already been commissioned, undergoes another commissioning process.

4.4.4.4.6 - Measurement and verification.

4.4.4.4.6.1 Measurement and verification (M&V) is the term given to the process for quantifying savings delivered by an Energy Conservation Measure (ECM), as well as the sub-sector of the energy industry involved with this practice. M & V demonstrates how much energy the ECM has avoided using, rather than the total cost saved.

4.4.4.4.7 - Landscaping

4.4.4.4.7.1 Irrigation: Consider water management which could include reducing storm-water run-off, preventing erosion and decreasing the effects of soil expansion.

4.4.4.4.7.2 Plant Materials: Consider Native materials, Xeriscaping.

4.4.4.4.7.3 Grass/ Sod Areas: Consider use of grass/ sod areas, consider water use, alternate options if planting sports fields.

4.4.4.4.8 - Permitting

4.4.4.4.8.1 Application for public school construction projects permits can be made at the DFPC website, www.colorado.gov/dfpc > Sections > Fire & Life Safety > Permits and Construction > School Construction.

4.4.4.4.8.2 If a local building department has entered into a memorandum of understanding (MOU) with DFPC, that local building department is considered a Prequalified Building Department (PBD). A School District may, at its discretion, choose to apply for permit through DFPC or the PBD that has jurisdiction of construction projects for the location of the school construction project. The list of PBD's is available on the DFPC website, School Construction.

4.5 The historic significance of existing public school facilities and their potential to meet current programming needs by rehabilitating such facilities.

4.5.1 Buildings that are 50 years or older at the time of application may be subject to the State Register Act 24-80.1-101 to 108 in determining if the affected properties have historical significance.

4.5.1.1 - Historical significance means having importance in the history, architecture, archaeology, or culture of this state or any political subdivision thereof or of the United States, as determined by the state historical society.

4.5.2 When determining if a facility should be replaced, the cost to rehabilitate versus the cost to replace should be evaluated.
