Continuous Positive-Pressure Ventilation (PPV) Sample Clauses

Continuous Positive-Pressure Ventilation (PPV). Vapor intrusion primarily occurs when there is a lower pressure inside the building, i.e., causing soil gas to flow into a building through cracks in the floor (U.S. EPA, 2002b). As such, the vapor intrusion process may be mitigated by creating a positive pressure (i.e., a pressure slightly higher than the outside air pressure) inside the building. When there is a positive pressure inside a building, air inside the building will flow outward through any cracks in the floor, i.e., toward the lower outdoor pressure. The U.S. EPA recognizes this in its vapor intrusion guidance, indicating: “A building may be positively pressurized as an inherent design of the heating, ventilation, and air conditioning system. It may be possible to show that the [vapor intrusion] pathway, in this case, is incomplete, at the current time, by demonstrating a significant pressure differential from the building to the atmosphere.” (U.S. EPA, 2002b) Similarly, the California Building Code (“CBC”), Section 1202.2.7, requires positive pressure ventilation in ticket booths and other occupied spaces inside of parking garages. The purpose in that case is to prevent fumes from the parking garage from entering those spaces, i.e., to mitigate vapor intrusion from the parking garage into those occupied spaces.

  • Heating, Ventilation and Air Conditioning Landlord shall furnish to the Premises heating, ventilation and air-conditioning (“HVAC”) in accordance with the Design Standards set forth in Exhibit D during Ordinary Business Hours. Landlord shall have access to all air-cooling, fan, ventilating and machine rooms and electrical closets and all other mechanical installations of Landlord (collectively, “Mechanical Installations”), and Tenant shall not construct partitions or other obstructions which may interfere with Landlord’s access thereto or the moving of Landlord’s equipment to and from the Mechanical Installations. No Tenant Party shall at any time enter the Mechanical Installations or tamper with, adjust, or otherwise affect such Mechanical Installations. Landlord shall not be responsible if the HVAC System fails to provide cooled or heated air, as the case may be, to the Premises in accordance with the Design Standards by reason of (i) any equipment installed by, for or on behalf of Tenant, which has an electrical load in excess of the average electrical load and human occupancy factors for the HVAC System as designed, or (ii) any rearrangement of partitioning or other Alterations made or performed by, for or on behalf of Tenant. Tenant shall install, if missing, blinds or shades on all windows, which blinds and shades shall be subject to Landlord’s approval, and shall keep operable windows in the Premises closed, and lower the blinds when necessary because of the sun’s position, whenever the HVAC System is in operation or as and when required by any Requirement. Tenant shall cooperate with Landlord and shall abide by the rules and regulations which Landlord may reasonably prescribe for the proper functioning and protection of the HVAC System. Tenant acknowledges that the server room in the Premises currently has three heat pumps installed, being two 4-ton units, and one 2.5-ton unit (the “Existing Heat Pumps”). The 2.5-ton unit is currently connected and operational. Tenant shall determine whether it is satisfied with the condition of the Existing Heat Pumps and Landlord shall not have any responsibility or liability for the condition, operation, maintenance, repair or replacement of the Existing Heat Pumps. Tenant may operate the Existing Heat Pumps. Tenant shall be responsible for, and pay directly for, all necessary maintenance and repairs to the Existing Heat Pumps. Tenant shall reimburse Landlord monthly for the cost of all utility services used to operate the Existing Heat Pumps within 10 Business Days after receipt of Landlord’s invoice for such amount. Landlord may measure Tenant’s usage of such utility services by either a sub-meter or by other reasonable methods such as by temporary check meters or by survey. Tenant, at its cost, may replace the Existing Heat Pumps with one or more new heat pumps, provided, however, that the capacity of such replacement heat pump(s) shall not exceed the 10.5-ton capacity cooling capacity of the Existing Heat Pumps.

  • HEATING, VENTILATING AND AIR CONDITIONING The Tenant will operate and regulate those portions of the heating, ventilating, and air conditioning equipment within and serving the Leased Premises so as to maintain such reasonable conditions of temperature and humidity within the Leased Premises as are determined by the Landlord and its Architect and engineers so that no direct or indirect appropriation of the heating, ventilating and air conditioning from the other portions of the Building occurs. The Tenant shall comply with such stipulations and with all Rules and Regulations of the Landlord pertaining to the operation and regulation of such equipment. The Tenant shall immediately notify the Landlord in the event that any repairs are required to the heating, ventilating and air conditioning equipment serving the Leased Premises and shall reimburse the Landlord as part of its Proportionate Share of Operating Costs for the cost of any maintenance, repairs or replacements made by the Landlord in respect of the heating, ventilating and air conditioning equipment serving the Leased Premises. The Landlord acknowledges that the Tenant shall not be responsible for the cost of capital repairs and capital replacements in respect of the heating, ventilating and air conditioning equipment serving the Leased Premises provided that such capital repairs and capital replacements are not necessitated by the Tenant's incorrect or negligent use of equipment. The Tenant shall not under any circumstances go onto the roof of the Building or make any maintenance repairs or replacements to the heating, ventilating and air conditioning systems in the Building without the prior written consent of the Landlord. If the Tenant fails to comply with such stipulations and Rules and Regulations, the Landlord shall be entitled to take such steps as it deems advisable to correct such defaults (including, without limitation, entering upon the Leased Premises and assuming control of such equipment) without liability to the Tenant, and the Tenant will pay to the Landlord forthwith upon demand as Additional Rent all costs and expenses incurred by the Landlord in so doing. The Landlord represents and warrants to the Tenant that the heating, ventilating and air conditioning equipment serving the Leased Premises and required to be installed by the Landlord pursuant to Schedule "C" is and will be at the Commencement Date in good working order and condition.

  • Electrical Service Subject to the limitation of this Paragraph 4, furnish electrical service to the Premises, including providing and installing all Building standard replacement lighting tubes. If Tenant uses more electrical power than Landlord in good faith considers reasonable or normal for office use, Tenant will pay Landlord on a monthly basis the cost of such excess power consumed by Tenant. Consumption will be determined, at Landlord’s election, either (a) by a survey performed by a reputable consultant selected by Landlord, or (b) through separate meters or submeters installed, maintained and read by Landlord at Tenant’s cost. For purposes of this Paragraph 4 only, “month” and “monthly” shall mean any billing period used by the utility or other power provider supplying electricity. All installations of electrical futures, appliances and equipment within the Premises shall be subject to Landlord’s prior approval, and if they affect the temperature or humidity otherwise maintained, Landlord may, at Tenant’s sole cost and expense (to be paid within (30) days after delivery of written demand supported by invoices or other reasonably satisfactory evidence), install supplemental air conditioning units. Tenant’s use of electricity shall never exceed Tenant’s share of the capacity of existing feeders to the Building or of the risers, wiring installations and transformers serving the floor(s) containing the Premises. Landlord shall provide up to 3.5 xxxxx per usable square foot (demand) of riser and floor panel electrical capacity averaged over the floor being serviced. EXHIBIT C Tenant shall be allocated an approximate 2.0 xxxxx per usable square foot for power and 1.5 xxxxx per usable square foot for lighting. Any risers or wiring necessary to meet Tenant’s excess electrical requirements will be installed by Landlord on Tenant’s request, at Tenant’s sole cost and expense (to be paid in advance), but only if in Landlord’s reasonable good faith belief they are necessary and will not cause damage to the Building or a dangerous condition, entail excessive or unreasonable alterations, repairs or expense, or disturb other occupants.
