SDG 7.2.1: Policy for ensuring all renovations/new builds are following energy efficiency standards

The most important topics are the following:

Building Envelope

Buildings envelopes shall b e in accordance with the requirements of the “Thermal Standard for Buildings in Lebanon” (TSBL) issued by the Ministry of Public Works and Transport – General Directorate of Urban Planning – in year 2005. Included buildings are all air conditioned or heated buildings, residential and non-residential, except for the following: l Buildings and parts of buildings that are intended for uses other than basic human occupancy, such as manufacturing, industrial processing, storage, etc.; l Buildings and parts of buildings that require particular indoor environmental conditions such as greenhouses, warehouses, etc.; l Places of worship; These requirements shall apply to: l External walls, roofs, and floors (where one side of the floor is exposed to ambient conditions) l Glazed elements The characteristics and altitude thresholds of the climatic zones, as well as the administrative districts related to each climatic zone are presented in the “Technical Guide for the application of the Thermal Standard for Buildings in Lebanon”.

Energy Efficiency

All buildings installing one or more of the following HVAC and domestic water heating systems shall comply with the requirements below, as applicable: a) DX Air conditioners: For all DX air conditioned buildings, DX air conditioning equipment shall comply with the minimum energy efficiency requirements and test procedures as indicated in Table 1.1. b) Water chilling packages: Water chilling packages shall comply with the minimum energy efficiency requirements and test procedures as indicated in Tables 1.2 and 1.3. Note: Equipment types not listed in Tables 1.1,1.2 and 1.3 should not be greater than the values presented in ASHRAE 90.1-2007 Table 6.8.1 (where applicable, values for before 1/1/2010). Equivalent “Eurovent” certified ratings are acceptable. c) Fuel Boilers: Boilers shall comply with the minimum energy efficiency requirements and test procedures as indicated in Table 1.4. Note 1: Boilers compliant with the requirements of ASHRAE 90.1-2007 Table 6.8.1F are acceptable. Note 2: Gas boilers and biomass boilers, when used, are exempted from the minimum energy efficiency requirements request indicated in Table 1.4. d) Service Water Heating: Hot water heaters shall comply with the maximum energy losses per 24 hours as indicated in Table 1.5 depending on heater volume V in liters.

Webinar on Climate Action in Construction and Building Industry.

As part of the efforts to enhance climate action among arab youth, the Islamic University of Lebanon, Yarmouk University, and Tanta University in collaboration with the American Concrete Institute (ACI) and the United Nations Economic and Social Commission for Western Asia (UN ESCWA), are organizing a Webinar on Climate Action in Construction and Building Industry. The Webinar will convene experts on climate change, green urban planning, and Construction material with university students from Arab countries.

In the webinar the speakers will go over:

➢ Improve understanding on the importance of addressing climate change in the Construction and Building Industry and the role of Arab youth in enhancing climate action in the region.

➢ Promote a science-policy interface through showcasing a comprehensive scientific assessment of the impacts of climate change on key sectors in the Arab region, based on findings from RICCAR, and how it supports climate-informed policymaking.

➢ Highlight the role of climate-responsive, green economy policy frameworks at the national and city levels, with examples from Jordan.

➢ Raising awareness about the impacts of construction materials on climate change and discussing ways to mitigate the environmental footprint of construction materials using innovative methods and technologies.
