Green Tech at a Glance

Although the proposed Tulsa Air and Space Museum Expansion is only in the schematic design phase, Tulsa-based KPI Architects Inc. has built a lot of green concepts into the building. With most of these concepts run through a building-wide Energy Management System, research is still ongoing for the technologies listed below and further technologies that may be utilized. This is a glance at the concepts being considered:
HVAC:
?%9Geothermal Heat Pumps – Utilizes ambient ground temperature to keep refrigerant at a constant temperature and allows heat dissipation into the soil.
??isplacement Ventilation – By introducing chilled air at floor level the system uses less energy to “blow” the air down and forces warm air towards the ceiling where the warm air is exhausted.
Lighting:
?%9Natural Light – The design uses natural light to provide indirect lighting, cutting the need for overhead lights and reducing energy usage, material costs and production input.
??ual Switching – Use of dual switches in overhead lighting gives the benefit of having three light levels to choose from.
?%9High-Efficiency T-8s – The most up-to-date and energy-efficient overhead lighting
?%9Occupancy Sensors – Sensors control lighting by switching lights on and off depending on occupants and movements in the room.
??aylight Sensors – Daylight sensors allow the user to maintain a constant light level in each room. The sensors work through the EMS to automatically dim the overhead lights depending on the amount of natural and indirect light available for a room throughout the day/night.
?%9LED Lighting – LED lighting provides indirect lighting at wall surfaces and at the LED screens with minimal heat transfer and low energy consumption.
Recycled / Reclaimed Materials
?%9Recycled Carpets – Carpets that meet and/or exceed specifications for the amount of recycled fabrics used to compose the material.
?%9Recycled Wall Coverings – Wall coverings that meet and/or exceed specifications for the amount of recycled fabrics used to compose the material.
?%9Reclaimed Water – A reclaimed water loop would be used for irrigation purposes.
Resilient Materials
??looring – Nora flooring would be utilized to provide a long-term high-impact flooring option to lower maintenance costs and to extend the life cycles of high traffic areas.
Innovative Design
?%9Orientation and tinting glass – The building is orientated to the northeast to provide maximum exposure to the public from Port Road and to minimize the exposure of to sunlight. The northeast side of the building also incorporate active tinting / frosting glass that assists in blocking direct light and minimizes solar heat transfer to the building envelope.
?%9LED Lights – LED lights will be used in the wall panels and other places to provide indirect lighting. This will minimize the number of traditional overhead lights required for the building.
?%9Solar Collection – Solar collecting technology will be used to power the LED lighting and water heaters.
??arth and Insulator – Portions of the building will be below grade allowing the spaces to use the natural insulating properties of the earth to help reduce heat and cooling loss.
??xterior Colors – Using light exterior colors and concrete allow the building to reflect solar radiation, lowering the net heat gain from solar heat transfer.
?%9Varying Overhangs – The window overhangs vary in size depending on their orientation and placement on the building in relation to the sun’s path. This allows the interior environment to receive maximum natural lighting with minimal direct lighting and heat gain.
